Description

Resource allocation method, rate matching method, transmission receiving point, and terminal

technical field

This application relates to the technical field of communication, and in particular to a resource configuration method, a transmission method in multi-connection mode, a method for rate matching by a terminal in multi-connection mode, a transmission receiving point, and a terminal supporting multi-connection mode.

Background technique

In the future fifth-generation (5th-Generation, 5G) mobile communication technology, with the rapid development of mobile communication, there are many aspects such as system capacity, instantaneous peak rate, spectrum efficiency, cell edge user throughput and delay. higher requirement. Therefore, a coordinated multiple points transmission/reception (CoMP) technology is proposed.

The CoMP technology aims to realize coordinated transmission between transmission receive points (TRP) in different geographic locations. At present, the CoMP technology can improve the system performance no matter in the uplink or the downlink, especially improve the spectrum efficiency at the edge of the cell. The current mainstream CoMP technology implementation methods can be divided into Joint Processing (Joint Processing, JP) technology and Coordinated Scheduling/Beamforming (Coordinated Scheduling/Beamforming, CS/CB) technology.

Non-coherent joint transmission (NCJT) is one of the important coordinated multi-point transmission schemes. In the NCJT scheme, two or more TRPs may serve the same terminal at the same time. When multiple TRPs cooperate, the control signaling supports multiple downlink control information (DCI), that is, the terminal can receive two DCIs indicating a physical downlink shared channel (PDSCH) at the same time.

In some cases, such as in non-ideal backhaul scenarios, the information transmission of two TRPs has a delay and cannot interact in real time, that is, at the same time, each TRP is in its own time-frequency resource To send data to the terminal, one TRP cannot know whether the other TRP is sending data to the terminal at this time, nor does it know which time-frequency resources the other TRP uses to send the data.

The terminal will send rate matching indication information to it according to the TRP to perform rate matching, that is, to perform puncturing processing on the time-frequency resources indicated by the rate matching indication information that are not used to transmit data information, because one TRP does not know another TRP Whether to send data, and on which time-frequency resources to send the data, so when each TRP sends a rate matching instruction to the terminal, it only considers its own situation, which will cause the terminal to make decisions based on the rate matching instruction information sent by multiple TRPs. When the rate is matched, a conflict occurs, so that the data information cannot be demodulated correctly.

Contents of the invention

This application provides a resource configuration scheme, a transmission scheme in multi-connection mode, and a rate matching scheme for terminals supporting multi-connection mode, which can solve the above-mentioned technical problems existing in the existing cooperative transmission scheme of multiple transmission receiving points, and can coordinate multiple The transmission and receiving point provides a rate matching instruction to the terminal, so that the terminal can perform rate matching correctly and avoid the failure to correctly demodulate data information.

A terminal in a multi-transmission receiving point (multi-TRP) scenario is usually configured with two downlink control configuration parameters, such as the first downlink control configuration parameter and the second downlink control configuration parameter; of course, the terminal may also be configured with two For the above downlink control configuration parameters, the first and second in the embodiment of the present application do not limit the number, but only indicate that they are not the same downlink control configuration parameter, which may refer to any two downlink control configuration parameters. The values of the first downlink control configuration parameter and the second downlink control configuration parameter may be the same or different.

The design of this embodiment of the present application to solve the technical problem is to configure or associate the first resource for transmitting non-data information to the terminal with the first downlink control configuration parameter as the configuration associated with the second downlink control configuration parameter A subset of the second resources indicated by the rate matching indication information to the terminal.

The "association" mentioned in the embodiment of this application can have a clear relationship, such as a one-to-one relationship, or an implicit relationship, such as from the downlink control configuration parameters and some related parameters, such as downlink control Information can be derived to correspond to resources.

Therefore, when configuring resources in this application, one way is: configure the resource for sending non-data information configured or associated in one of the downlink control configuration parameters as the rate matching indication information associated with another downlink control configuration parameter to the A subset of resources indicated by the endpoint. Another way is: configure a resource for sending data information configured in a downlink control configuration parameter or association as one of the resources indicated by the rate matching indication information associated with another downlink control configuration parameter and other resources for transmitting non-data information A subset of external resources.

This application is mainly described in the former way. Since resources for transmitting data information or resources for transmitting non-data information are often complementary to each other, the technical principles of the two methods are the same. As long as the above-mentioned purpose of limiting resources is met, All belong to the protection scope of this application.

The downlink control configuration parameters mentioned in all the embodiments of this application include physical downlink control channel configuration, or control resource set group, or search space group.

In the embodiment of this application, for multiple transmission and receiving point scenarios, when configuring downlink control configuration parameters to the terminal, the following three configuration methods can be used:

2. Configure a physical downlink control channel configuration to the terminal, which includes two control resource set groups (control resource set group, CORESE group), each control resource set group contains several control resource sets, and each control resource set is associated with multiple search space.

3. Configuring a physical downlink control channel configuration for the terminal, which includes two search space groups, each search space group includes several search spaces, and each search space is associated with a control resource set.

Generally, in the scenario of multiple transmission and receiving points, if two physical downlink control channel configurations are configured to the terminal in method 1, the terminal can detect two downlink control information from the two physical downlink control channel configuration indication control information resources respectively .

Alternatively, in mode 2, when two control resource sets are configured to the terminal, the terminal can respectively detect two downlink control information from the control information resources indicated by the two control resource sets.

Another way is: configure the resources for transmitting data information at one transmission and reception point as a subset of resources other than the resources indicated by another transmission and reception point to the terminal through rate matching indication information and other resources for transmitting non-data information .

In this way, it is possible to avoid failure to correctly demodulate data information due to the overlapping of resources for sending data information and resources for sending non-data information at two transmission and reception points, and conflicts when the terminal performs rate matching.

Detailed ways

The technical scheme of the present application can be specifically applied in various communication systems, such as: Global system for mobile communications (Global system for mobile communications, GSM), code division multiple access (Code Division Multiple Access, CDMA), wideband code division multiple access (Wideband Code Division Multiple Access, WCDMA), Time Division-Synchronous Code Division Multiple Access (Time Division-Synchronous Code Division Multiple Access, TD-SCDMA), Universal Mobile Telecommunications System (Universal Mobile Telecommunications System, UMTS), Long Term Evolution (LTE ) system, etc. With the continuous development of communication technology, the technical solution of the present application can also be used in future networks, such as 5G system, which can also be called New Radio (New Radio, NR) system, or can be used for device to device (device to device device, D2D) system, machine to machine (machine to machine, M2M) system and so on.

The network equipment involved in this application may refer to an entity on the network side for sending or receiving information, such as a base station, or a transmission point (transmission point, TP), transmission and reception point (transmission and reception point, TRP) , relay equipment, or other network equipment with base station functions, etc., are not limited in this application. The communication device involved in this application may be a centralized control module, or other network devices.

In this application, a terminal device is a device with a communication function, which may include a handheld device with a wireless communication function, a vehicle-mounted device, a wearable device, a computing device or other processing devices connected to a wireless modem, and the like. Terminal equipment can be called different names in different networks, for example: terminal (terminal), user equipment (userequipment, UE), mobile station, subscriber unit, relay, station, cellular phone, personal digital assistant, wireless modem, wireless Communication equipment, handheld devices, laptop computers, cordless phones, wireless local loop stations, etc. The terminal device may refer to a wireless terminal or a wired terminal. The wireless terminal can be a device that provides voice and/or data connectivity to the user, a handheld device with a wireless connection function, or other processing devices connected to a wireless modem, which can be connected via a wireless access network (such as RAN, radio access network) communicates with one or more core networks.

As shown in Figure 1, Figure 1 is a schematic diagram of multi-transmission receiving point cooperative transmission provided by the embodiment of the present application. Figure 1 uses transmission receiving point 1 (TRP1) and transmission receiving point 2 (TRP2) to transmit data for the terminal respectively As an example, it is not ruled out that in the scenario where multiple transmission and receiving points coordinate transmission, there are more than two TRPs that transmit data for the terminal respectively. The technical solution described in the application.

TRP1 and TRP2 shown in FIG. 1 communicate with the terminal respectively, and there is no real-time intercommunication between them. TRP1 and TRP2 do not know each other's resources for sending data information to the terminal and resources for transmitting non-data information. For example, TRP1 in Figure 1 transmits data information to the terminal on the data transmission resource shown on the left side of Figure 1, and TRP2 transmits non-data information to the terminal on the resource where the "channel state information reference signal" shown on the right side of Figure 1 is located Or do not send data information. Wherein, a square in FIG. 1 represents a resource element (resource element, RE), and the resource indicated by the rate matching indication information is the resource represented by the black square shown on the right. The resources outside the black square part indicate the resources that TRP2 can transmit data to the terminal. The terminal will perform punching operations on the corresponding resources (resources indicated by the square part on the right) according to the rate matching instruction information sent to it by TRP2. TRP2 will not transmit data information to the terminal on these resources, and the terminal will also use these resources. data demodulation.

Comparing the resources for TRP1 to transmit data to the terminal and the resources for TRP2 to transmit data information and non-data information to the terminal, it can be seen that when the terminal performs rate matching, after punching out the resources for TRP2 to transmit non-data information, TRP1 is still transmitting on these resources Data information, so it will affect the terminal to perform data demodulation.

Therefore, it is necessary to configure resources for sending data information or non-data information by TRP1.

A terminal in a multi-transmission receiving point (multi-TRP) scenario is usually configured with two downlink control configuration parameters, such as the first downlink control configuration parameter and the second downlink control configuration parameter; of course, the terminal may also be configured with two For the above downlink control configuration parameters, the first and second in the embodiment of the present application do not limit the number, but only indicate that they are not the same downlink control configuration parameter, which may refer to any two downlink control configuration parameters. The values of the first downlink control configuration parameter and the second downlink control configuration parameter may be the same or different.

The design of this embodiment of the present application to solve the technical problem is to configure or associate the first resource for transmitting non-data information to the terminal with the first downlink control configuration parameter as the configuration associated with the second downlink control configuration parameter A subset of the second resources indicated by the rate matching indication information to the terminal.

The "association" mentioned in the embodiment of this application may have a clear relationship, such as a one-to-one relationship, or an implicit relationship, such as from the downlink control configuration parameters and some related parameters, such as downlink The control information can deduce the corresponding resource.

From the perspective of resource allocation:

One way is: configure the resources for sending non-data information configured or associated in one of the downlink control configuration parameters as a subset of the resources indicated to the terminal by the rate matching indication information associated with another downlink control configuration parameter. Another way is: configure the resources for sending data information configured or associated in one downlink control configuration parameter as one of the resources indicated by the rate matching indication information associated with another downlink control configuration parameter and other resources for transmitting non-data information A subset of external resources.

This application is mainly described in the former way. Since resources for transmitting data information or resources for transmitting non-data information are often complementary to each other, the technical principles of the two methods are the same. As long as the above-mentioned purpose of limiting resources is met, All belong to the protection scope of this application.

The downlink control configuration parameters mentioned in all the embodiments of this application include physical downlink control channel configuration, or control resource set group, or search space group.

For a single transmission and receiving point, configure downlink control configuration parameters to the terminal, usually a physical downlink control channel configuration, in which multiple control resource sets and multiple search spaces are configured; one control resource set Multiple search spaces can be associated. Specifically, a search space includes a field used to indicate its associated control resource set. For example, a PDCCH-config configures 3 CORESETs and 10 search spaces, the first CORESET among the 3 CORESETs is associated with the first search space, the second search space, the third search space, the first search space, The second search space and the third search space include identifiers (identifiers, IDs), for example, ID=1, indicating that they are associated with the first CORESET.

For the scenario of multiple transmission and receiving points, when configuring the downlink control configuration parameters to the terminal, there are the following three configuration methods:

1. Configure two physical downlink control channel configurations (PDCCH-config) to the terminal, and each physical downlink control channel configuration (PDCCH-config) is configured with multiple control resource sets (CORESET) and multiple search spaces, wherein one A control resource set can be associated with multiple search spaces.

2. Configure a physical downlink control channel configuration (PDCCH-config) to the terminal, which includes two control resource set groups (CORESE groups), each control resource set group (CORESET group) contains several control resource sets (CORESET), Each control resource set is associated with multiple search spaces.

For example, configure PDCCH-config-1 to the terminal, PDCCH-config-1 configures CORESET group-1, CORESET group-2, CORESET group-1 includes CORESET-1, CORESET-2, CORESET-3, CORESET-1 associated search space -1, search space1-2, search space-3; CORESET group-2 includes CORESET-4, CORESET-5, CORESET-6, CORESET-4 associated search space-4, search space1-5, search space-6, etc. . Others and so on.

3. Configure a physical downlink control channel configuration (PDCCH-config) for the terminal, which includes two search space groups, each search space group includes several search spaces, and each search space is associated with a control resource set.

For example, configure PDCCH-config-1 to the terminal, PDCCH-config-1 configures search space group-1, search space group-2; search space group-1 includes search space-1, search space1-2, search space-3; search space group-2 includes search space-4, search space-5, and searchspace-6; among them, search space-1 is associated with CORESET-1, search space-2 is associated with CORESET-2, and so on.

Generally, in the scenario of multiple transmission and receiving points, if two physical downlink control channel configurations are configured to the terminal in method 1, the terminal can detect two downlink control information from the two physical downlink control channel configuration indication control information resources respectively . For example, PDCCH-config-1 and PDCCH-config-2 may be directly indicated to the terminal, and DCI-1 and DCI-2 are respectively detected from control information resources respectively indicated by PDCCH-config-1 and PDCCH-config-2.

Alternatively, in mode 2, when two control resource sets are configured to the terminal, the terminal can respectively detect two downlink control information from the control information resources indicated by the two control resource sets. For example, CORESET group-1 and CORESET group-2 may be directly indicated to the terminal, and DCI-1 and DCI-2 are respectively detected from the control information resources respectively indicated by CORESET group-1 and CORESET group-2.

Alternatively, in mode 3, when two search space groups are configured to the terminal, the terminal can respectively detect two downlink control information from the control information resources indicated by the two search space groups. For example, searchspace group-1 and search space group-2 may be directly indicated to the terminal, and DCI-1 and DCI-2 are respectively detected from the control information resources respectively indicated by search space group-1 and search space group-2.

Here, two physical downlink control channel configurations or two control resource set groups or two search space groups are taken as an example for illustration, and the case of more than one can be deduced by analogy.

From the point of view of the transmission and receiving point: One way is to limit the resources for TRP1 to send non-data information to the resources indicated by TRP2 to the terminal through the rate matching indication information, which may be the same as the resources indicated by the rate matching indication information, or It is a subset of resources indicated by the rate matching indication information. For example, as shown in Figure 2, the resource that TRP1 sends non-data information (the resource shown in the white square on the left) is the resource that does not send data information or the resource that sends non-data information. In short, it is the resource that does not send data information. The resources that do not send data information or do not send data information (resources shown in the black square part on the right) are the same. With this design, TRP1 does not send data information on resources where TRP2 sends non-data information, and the terminal can normally perform rate matching according to the rate matching instruction information of TRP2, so as to correctly demodulate data.

Another way is to limit the resources for TRP1 to transmit data information to a subset of resources other than the resources indicated by TRP2 to the terminal through the rate matching indication information. For example, as shown in Figure 2, the resources for TRP1 to send data information (resources shown in the left square part) are the same as the resources other than the resources indicated by TRP2 through the rate matching indication information, that is, the resources for TRP2 to send data information (right white The resources shown in the boxed section) are the same. Certainly, the resource for sending data information by TRP1 may also be a subset of the resource for sending data information by TRP2. This design makes TRP1 not send data information on resources where TRP2 sends non-data information, and the terminal can normally perform rate matching according to the rate matching indication information of TRP2, so as to correctly demodulate data.

Another way is to restrict the TRP1 from sending data information on the resources indicated by the TRP2 to the terminal through the rate matching indication information. For example, as shown in Figure 2, the resources indicated by TRP2 to the terminal through the rate matching indication information (resources shown in the square part on the right) are resources for transmitting non-data information or not sending data information between TRP2 and the terminal, directly restricting TRP1 in these resources. Data cannot be sent on the resource, and the purpose of rate matching in this application can also be achieved, helping the terminal to demodulate data correctly.

Another way is to restrict TRP1 from sending data information to the terminal on resources other than those indicated by the rate matching indication information to the terminal in TRP2. For example, as shown in FIG. 2 , TRP2 sends data information transmitted between TRP2 and the terminal to resources (resources shown in the square part on the right) other than the resources (resources shown in the square part on the right) indicated by the rate matching indication information to the terminal. resources, directly restricting TRP1 from sending data on these resources can also achieve the purpose of rate matching in this application and help the terminal to demodulate data correctly.

This application is mainly described in the former way. Since the resources for transmitting data information or the resources for transmitting non-data information are often complementary to each other, the technical principles of the several ways are the same, as long as the above-mentioned purpose of limiting resources is met, All belong to the protection scope of this application.

The above-mentioned limitation of resources for TR1 and TRP2 to send data or non-data information can be performed by limiting their corresponding downlink control configuration parameters, specifically as the above-mentioned resource configuration method, which will not be repeated here.

In this way, it is possible to avoid failure to correctly demodulate data information due to the overlapping of resources for sending data information and resources for sending non-data information at two transmission and reception points, and conflicts when the terminal performs rate matching.

The meanings of transmission and sending mentioned in this application are the same, unless otherwise specified, the two can be interchanged.

The technical solutions provided in this application can be applied to non-ideal backhaul scenarios with multiple transmission and reception points, and can also be applied to ideal backhaul (ideal backhaul) scenarios. In the non-ideal backhaul scenario, there is a delay in the information transmission of the two TRPs, and they cannot interact in real time. Therefore, if one TRP sends data information on the resource where the other TRP sends non-data information or does not send data information, it will affect the terminal. Demodulate the data. In an ideal backhaul scenario, although two TRPs interact in real time, similar technical problems may occur. Therefore, the technical solution of this application is also applicable to an ideal backhaul scenario.

Based on this, the present application designs both resource configuration for the terminal and rate matching technology for the terminal, so as to achieve the above purpose.

Referring to FIG. 3 , it is a schematic flowchart of a method for resource configuration and rate matching by a terminal in multi-connection mode provided by the present application.

Step 100, configure at least two downlink control configuration parameters to the terminal; in other words, the terminal is configured with at least two downlink control configuration parameters; the downlink control configuration parameters include physical downlink control channel configuration or search space group; for the convenience of description, It is assumed that the at least two downlink control configuration parameters include a first downlink control configuration parameter and a second downlink control configuration parameter.

Step 101, configure the first resource configured or associated with the first downlink control configuration parameter for transmitting non-data information to the terminal as the rate matching instruction information associated with the second downlink control configuration parameter indicated to the terminal A subset of the second resource. In other words, the first resource configured by the terminal is a subset of the second resource; wherein, the first resource is a resource for transmitting non-data information configured or associated with the first downlink control configuration parameter, and the second resource is the second resource The resource indicated by the rate matching indication information associated with the downlink control configuration parameter to the terminal.

The configuration related operations of configuring at least two downlink control configuration parameters to the terminal; configuring the first resource for the terminal to transmit non-data information, and configuring the first resource as a subset of the second resource may be as shown in FIG. 2 It may be performed by the first transmission receiving point TRP1, or may be performed by the second transmission receiving point TRP2, or may be performed by other TRPs except TRP1 and TRP2.

That is to say, the first transmission reception point TRP1 can configure at least two downlink control configuration parameters for the terminal, configure resources for transmitting non-data information to the terminal for itself, and co-locate multiple transmission reception points with the first transmission reception point TRP1 for coordinated transmission The second transmission reception point TRP2 in the scenario can also configure resources for the transmission of non-data information for the first transmission reception point TRP1, where the second transmission reception point TRP2 is one of the multiple transmission reception points other than the first transmission reception point TRP1 Either one, in this embodiment of the application, the first transmission reception point TRP1 or the second transmission reception point TRP2 indicates a certain transmission reception point, and does not limit its number or order.

Of course, the first transmission and reception point TRP1 may also configure at least two downlink control configuration parameters for the terminal, and configure resources for the second transmission and reception point TRP2 to transmit data or non-data information to the terminal. In short, any one of the multiple transmission and reception points in the multi-connection mode can configure at least two downlink control configuration parameters for the terminal in the multi-connection mode, and then configure itself or other transmission and reception points to transmit to the terminal. A resource of data information or non-data information. The manner of configuring the first resource may also be that the transmission receiving point configures the terminal through high-level signaling, such as radio resource control (radio resource control, RRC) signaling, or through other downlink signaling, such as media access control control element ( Media access control control element, MAC-CE) signaling, select one or more indications from multiple resources configured by RRC to the terminal.

The resources mentioned in all the embodiments of this application may be time-domain resources, frequency-domain resources, or air-domain resources, or a combination of any two or more of the three resources.

Wherein, the second resource indicated by the second transmission and reception point TRP2 to the terminal through the rate matching indication information is a resource that does not send data information or a resource that sends non-data information.

Step 102, the terminal receives non-data information on the subset of the second resource; wherein, the subset of the second resource is the first resource, and the first resource is the first downlink configured by the terminal A control configuration parameter configures or associates a resource that transmits non-data information. The first downlink control configuration parameters include any one or more items of the first physical downlink control channel configuration, the first control resource set group, and the first search space group.

Step 103, the terminal receives the rate matching indication information carried in the second downlink control information; the rate matching indication information indicates the second resource; wherein, the second downlink control information is the second resource configured by the terminal detected in the control information resource indicated by two downlink control configuration parameters; wherein, the second downlink control configuration parameter includes any one of the second physical downlink control channel configuration or the second control resource set group or the second search space group or more; that is, the second downlink control information is any one or more indications of the second physical downlink control channel configuration, the second control resource set group, and the second search space group configured by the terminal It is detected in the control information resource of , optionally, the second physical downlink control channel configuration or the second search space group is related to the second transmission reception point TRP2.

It should be noted that there is no limitation on the order of the above steps 102 and 103.

Step 104, the terminal performs rate matching according to the second resource indicated by the rate matching indication information.

It should be noted that step 104 is executed after step 103, but there is no sequence limitation between step 104 and step 102.

Wherein, when the terminal performs rate matching, no data information will be transmitted on the aforementioned resources that do not send data information or resources that send non-data information, so they need to be punctured, and the terminal does not demodulate data on these resources. The transmission of non-data information mentioned in this application may refer to resources for transmission of reference signals, resources for transmission of control channels or resources for transmission of control signals, or resources for transmission of no data information.

The above-mentioned configuration resources of this application and the technical solution for terminal rate matching in multi-connection mode can be applied to the scenario where multiple transmission and reception points need to perform rate matching when multiple transmission and reception points coordinate transmission, for example, the transmission and reception points pass the channel state The scenario where the information reference signal instructs the terminal to perform rate matching, or the scenario where the transmission and receiving point instructs the terminal to perform rate matching through a rate matching pattern, or the scenario where the transmission and receiving point instructs the terminal to perform rate matching through a demodulation reference signal, the application provides The scenarios where the technical solution can be implemented are not limited to this.

In the following, the scenario where the transmission and reception point instructs the terminal to perform rate matching through the channel state information reference signal, the scenario in which the transmission and reception point instructs the terminal to perform rate matching through the rate matching pattern, and the transmission and reception point to instruct the terminal to perform rate matching through the demodulation reference signal The matching scenario is taken as an example to introduce the embodiment of this application.

Embodiment one

In the first embodiment, the transmission and receiving point instructs the terminal to perform rate matching through the channel state information reference signal as an example for illustration.

In the multi-transmission reception point (multi-TRP) scenario shown in Figure 2, it is assumed that the rate matching indication information sent by the second transmission reception point TRP2 to the terminal indicates an aperiodic zero power channel state information reference signal resource set (aperiodic zero power channel state information-reference signal resource set, aperiodicZP CSI-RS resource set); the resource in the aperiodic zero-power channel state information reference signal resource set is called the second resource; the non-data information transmitted by the first transmission and reception point TRP1 to the terminal It is: aperiodic non-zero power channel state information-reference signal (aperiodic non-zero power channel state information-reference signal, aperiodic NZP-CSI-RS), and the resource for transmitting the aperiodic non-zero power channel state information-reference signal is called the first resource.

Referring to FIG. 4, there are multiple aperiodic zero-power channel state information reference signal resource sets sent by the second transmission and reception point TRP2 to the terminal, such as pattern 1 (pattern1), pattern 2 (pattern2), and pattern 3 ( The three sets shown in the black square part of pattern3). As shown in the lower left corner of Figure 4, in all transmission time units, such as time slots (slots), when TRP2 sends PDSCH to the terminal, it punches holes in all aperiodic ZP CSI-RS resource sets, that is, does not send PDSCH on these resource positions, Referring to the lower left corner of Figure 4, the black squares are resource elements (resource elements, REs) for sending PDSCH, and the white squares are punched REs. Here, the resource of the aperiodic zero-power channel state reference signal is the union of the three sets shown in pattern 1, pattern 2, and pattern 3.

The lower right corner of Figure 4 is the resource (shown in black square) for TRP1 to send aperiodic non-zero power channel state information reference signal to the terminal. Here, the resource that restricts TRP1 to send aperiodic non-zero power channel state information reference signal to the terminal is TRP2 A subset of resources for transmitting an aperiodic zero-power channel state reference signal to the terminal. Of course, restricting the resources for TRP1 to send aperiodic non-zero-power channel state information reference signals to terminals is all the resources for TRP2 to send aperiodic zero-power channel state reference signals to terminals, and the same technical effect can also be achieved. In other words, the resource corresponding to the aperiodic non-zero power channel state information reference signal sent by TRP1 to the terminal is a subset of the resource corresponding to the union of multiple aperiodic zero power channel state information reference signal resource sets sent by TRP2 to the terminal.

After the above configuration, TRP1 does not need to notify TRP2 of the NZP-CSI-RS resource to be sent by TRP1, and the resource of NZP-CSI-RS to be sent by TRP1 will not conflict with the resource of PDSCH sent by TRP2 to the terminal. TRP2 instructs the terminal to puncture the REs that transmit the ZP-CSI-RS corresponding to all the patterns (such as pattern1, pattern2, pattern3).

In this embodiment, TRP2 instructs the terminal to puncture REs that transmit ZP-CSI-RS in all patterns indicated in the RRC signaling, and independent signaling can be added to indicate, or downlink control information can be multiplexed (downcontrol information, DCI) existing reserved (reserved) signaling to indicate. The terminal thinks that all the resource REs that transmit ZP-CSI-RS corresponding to all patterns (such as pattern1, pattern2, pattern3) have not sent PDSCH, and the terminal performs rate matching (ratematching) according to all aperiodic ZP CSI-RS resource sets sent to it by TRP2 .

Referring to Figure 5, the set of aperiodic zero-power channel state information reference signal resources sent by the second transmission and reception point TRP2 to the terminal is one, that is, when resources are configured for the terminal, it is in a multi-transmission reception point (multi-TRP) scenario Only one aperiodic ZP CSI-RS resource set is configured for the terminal through RRC signaling for any one of the TRPs, or multiple Choose one from the aperiodic ZP CSI-RS resource set. If such configuration is not performed, TRP1 needs to notify TRP2 in advance of the resource and time of the NZP-CSI-RS to be sent by TRP1 through a backhaul.

In this scenario, the resource that needs to be restricted from the first transmission and reception point TRP1 to send the aperiodic non-zero-power channel state information reference signal to the terminal is the resources in an aperiodic zero-power channel state information reference signal resource set sent by TRP2 to the terminal Subset.

In a specified time unit, for example, in a certain time slot (slot), when TRP2 communicates with the terminal, the resource corresponding to pattern 2 (pattern2) is used, and TRP2 transmits the ZP CSI-RS corresponding to pattern 2 (pattern2) RE. Punch. As shown in the lower left corner of Figure 5, the black squares represent the REs that TRP2 sends PDSCH to the terminal, and the white squares represent the REs that TRP2 sends ZP CSI-RS to the terminal.

TRP2 instructs the terminal to perform rate matching through the zero power channel state information reference signal trigger (ZP CSI-RS trigger) field of DCI, and the ZP CSI-RS trigger field indicates at most 3 aperiodic ZP CSI-RS resource sets that have been configured. One (such as the aperiodic ZP CSI-RS resource set corresponding to pattern2), and the PDSCH is not sent on the RE corresponding to the aperiodic ZP CSI-RS resource set. At this time, TRP1 sends aperiodic NZP CSI-RS resources to the terminal, which is a subset of resources in an aperiodic ZP CSI-RS resource set corresponding to pattern2 sent by TRP2 to the terminal. As shown in the lower right corner of Figure 5, TRP1 represented by the black square sends REs of aperiodic NZP CSI-RS to the terminal, which is a subset of resources in an aperiodic ZP CSI-RS resource set corresponding to pattern2. Of course, TRP1 sends the RE of aperiodic NZP CSI-RS to the terminal, which is all the resources in an aperiodic ZP CSI-RS resourceset corresponding to pattern2, and can also achieve the technical effect of this embodiment.

The terminal performs rate matching according to the instructions of the DCI, that is, the terminal believes that no PDSCH is sent on the aperiodic ZP CSI-RS resource set indicated by the ZP CSI-RS trigger field, so the terminal sends the pattern indicated by the ZP CSI-RS trigger field The corresponding RE that transmits the ZP CSI-RS performs puncturing.

In the first embodiment, one TRP can avoid sending data information on the resource where another TRP sends a channel state information reference signal to the terminal, and the terminal can perform rate matching according to the channel state information reference signal resource or resource set indicated to it by the transmission receiving point , data demodulation is not performed on resources for transmitting channel state information reference signals, but data is correctly demodulated on other resources.

Embodiment two

The second embodiment is described by taking the transmission receiving point instructing the terminal to perform rate matching through a rate matching pattern as an example.

First, for a single TRP, the downlink control information it sends to the terminal includes a field rate matching indicator (rate matching indicator), which indicates multiple rate matching pattern groups configured for the terminal in the form of a bitmap (bitmap) ( rateMatchPatternGroup) is activated.

As shown in Figure 6, TRP configures multiple rate matching patterns (rateMatchPattern) and multiple (usually one or two) rate matching pattern groups (rateMatchPatternGroup) through PDSCH-config in RRC signaling, and each rateMatchPatternGroup indicates several rateMatchPattern, of course, there may also be some configured rateMatchPatterns that are not indicated by any rateMatchPatternGroup, such as the rate matching patterns in the rate matching pattern list outside the rate matching pattern group shown in Figure 6 (in Figure 6, each small A square represents a rateMatchPattern).

Normally, each rate matching pattern (rateMatchPattern) may have two ways to indicate resources. One way is to indicate the frequency domain and time domain respectively through the resource block (resource block, RB) and the bitmap (bitmap) corresponding to the symbol. The resource location of the domain, another way is to indicate a control resource set (CORESET).

After receiving the DCI sent by the TRP, the terminal performs rate matching according to the indication of the rate matching indicator field in the DCI. The specific method of rate matching is:

One way is: the terminal uses the rate matching pattern (rateMatchPattern) indicated in the rate matching pattern group (rateMatchPatternGroup) indicated by the DCI rate matching indication field, and the two rate matching pattern groups 1 and 2 (Group 1 and Group2) None of the rate matching patterns included are punched. As shown in Figure 7, adding the value of the rate matching indication field to 10 indicates the rate matching pattern indicated in Group 1 (Group1) in the rate matching pattern group, and the rate matching pattern that is not included in the two rate matching pattern groups. All the resources indicated by the rate matching patterns in the matching pattern list (rateMatchPatternList) need to be punctured, specifically as shown in FIG. 7 , the black square indicates that the resources indicated by the rate matching pattern are punctured.

Another way is that, if the resource indicated by the rate matching pattern (rateMatchPattern) is a CORESET, all control information resources indicated by the search space (search space) associated with this CORESET are punctured.

Referring to FIG. 2 , in the second embodiment, TRP1 , TRP2 and the terminal are in a multi-transmission reception point (multi-TRP) scenario. The terminal will receive downlink control information from TRP1 and downlink control information from TRP2. For the sake of clear description, the first downlink control information indicates the downlink control information sent by the first transmission receiving point to the terminal, and the second downlink control information indicates the downlink control information sent by the second transmission receiving point to the terminal, and the terminal The downlink control information is not distinguished from which transmission and reception point, and the "first" and "second" here do not indicate the number of downlink control information, nor the number of downlink control information.

The first downlink control information is associated with the first physical downlink control channel configuration (PDCCH-config-1), and the second downlink control information is associated with the second physical downlink control channel configuration (PDCCH-config-2).

For the first transmission reception point TRP1, the rate matching indication information sent to the terminal is carried in the first downlink control information; for the second transmission reception point TRP2, the rate matching indication information sent to the terminal is carried in the In the second downlink control information.

For the first transmission and reception point TRP1 or the second transmission and reception point TRP2, there are corresponding physical downlink shared channel configuration and physical downlink control channel configuration, and the physical downlink shared channel configuration and physical downlink control channel configuration of the same transmission and reception point are mutually exclusive. associated.

In this embodiment, it is necessary to configure the resources for TRP1 and TRP2 to communicate with the terminal, specifically, limit the resources indicated by the physical downlink control channel configuration (PDCCH-config) associated with a physical downlink shared channel configuration (PDSCH-config), Or the resource indicated by the control resource set group (CORESET group), or the resource indicated in the search space group (search spacegroup), is the rate matching pattern (rateMatchPattern) indicated in another physical downlink shared channel configuration (PDSCH-config), but not in A subset of resources indicated by a rate matching pattern (rateMatchPattern) in any rate matching pattern group (rateMatchPatternGroup).

As shown in Figure 8, the terminal is configured with two PDSCH-configs, PDSCH-config-1 and PDSCH-config-2 respectively; each PDSCH-config indicates several rateMatchPatterns and at most two rateMatchPatternGroups.

The terminal is also configured with two PDCCH-configs, namely PDCCH-config-1 and PDCCH-config-2; or the terminal is also configured with two CORESET groups under one PDCCH-config, or the terminal is also configured with Two search space groups under one PDCCH-config.

Moreover, the terminal is also configured with two PDCCH-configs (or two CORESET groups, or two searchspace groups) respectively associated with two PDSCH-configs, and one PDCCH-config is associated with one PDSCH-config respectively. For example, PDCCH-config-1 is associated with PDSCH-config-1, which are related to TRP1. PDCCH-config-2 is associated with PDSCH-config-2, which are related to TRP2.

In this embodiment, the rate matching instruction information sent by the second transmission and reception point TRP2 to the terminal directly indicates the rate matching pattern in the rate matching pattern group configured in the second physical downlink shared channel configuration (PDSCH-config-2), That is to say, which rate matching pattern in the rate matching pattern group should be punctured; and the second resource referred to in this embodiment is configured in the second physical downlink shared channel configuration, except that the rate matching indication information is not The resource corresponding to the rate matching pattern outside the activated rate matching pattern group, so the rate matching indication information indirectly indicates the configuration in the second physical downlink shared channel configuration by indicating the rate matching pattern group configured in the second physical downlink shared channel configuration The second resource corresponding to the other rate matching pattern.

Correspondingly, as indicated by the first physical downlink control channel configuration (PDCCH-config) or the first control resource set group (CORESET group) or the first search space group (search spacegroup) associated with the first physical downlink shared channel configuration The resource is configured as a subset of resources corresponding to rate matching patterns configured in the second physical downlink shared channel configuration except for the rate matching pattern group for which the rate matching indication information is not activated.

Specifically, in this embodiment, the resources indicated by the PDCCH-config-1 associated with the PDSCH-config-1, or the resources indicated by the control resource set group (CORESET group), or the resources indicated by the search space group (search space group) are limited. Resource 1 is the rate matching pattern (rateMatchPattern) indicated in PDSCH-config-2, but not a subset of resource 2 indicated by the rate matching pattern (rateMatchPattern) in any rate matching pattern group (rateMatchPatternGroup). At the same time, restrict the PDCCH-config-2 associated with PDSCH-config-2 or the control resource set group (CORESET group), or the resource 2 indicated in the search space group (search space group), which is the rate indicated in PDSCH-config-1 A subset of resource 1 indicated by a rateMatchPattern that matches the pattern (rateMatchPattern), but is not in any rateMatchPatternGroup.

Wherein, the above-mentioned physical downlink control channel configuration may include one or more physical control channel configuration parameters or index numbers of physical control channel configuration parameters; the control resource set group may include one or more control resource set parameters or control resource set parameters Index number; a search space group can include one or more search spaces or index numbers of search spaces.

During specific implementation, TRP1 and TRP2 send DCI to the terminal respectively, and indicate a rate matching indicator (rate matching indicator) in the respective DCIs, and at the same time perform puncturing on the PDSCH sent respectively according to the indication of the rate matching indicator (rate matching indicator) ( That is, no PDSCH is sent on the resource indicated by the rate matching indicator)

For the PDSCH indicated by the DCI detected in the control information resource indicated by each PDCCH-config (or CORESET group or CORESET, or search spacegroup, or search space), the terminal uses the PDSCH-config associated with the PDCCH-config The indicated rateMatchPatternGroup and rateMatchPattern are combined with the indication of the Rate matching indicator field in the DCI for rate matching.

The specific method for the terminal to perform rate matching is as follows: the terminal indicates the rate matching pattern (rateMatchPattern) indicated in the rate matching pattern group (rateMatchPatternGroup) of 1 in the rate matching indicator field of DCI, and two rate The rate matching patterns (rateMatchPattern) not included in the matching pattern group (rateMatchPatternGroup) are all punched. Wherein, if the resource indicated by the rate matching pattern (rateMatchPattern) is a control resource set (CORESET), all search space (search space) resources associated with the control resource set (CORESET) are punched.

If the terminal detects DCI in both resource sets configured by the PDCCH-config, it performs the above processing on the two PDSCHs indicated by the two DCIs. In this way, the resources used by one TRP to send the PDCCH can ensure that holes are punched in the PDSCH of another TRP.

In the second embodiment, one TRP can prevent one TRP from sending data information on the resource for rate matching indicated by another TRP, and the terminal can perform rate matching according to the rate matching pattern indicated by any TRP, so as to correctly demodulate data.

Embodiment Three

In the third embodiment, the rate matching indication information sent by the second transmission and reception point to the terminal is carried in the second downlink control information; the second downlink control information is the second physical downlink control channel with the second transmission and reception point Configure corresponding. The difference from the scenario of the above-mentioned embodiment is that in the third embodiment, the rate matching indication information indicates a code division multiplexing group (code division multiplexing, CDM), and the code division multiplexing group is a code division multiplexing group that does not carry data information. group; the second resource is the resource indicated by the code division multiplexing group. The first resource is the resource indicated by the demodulation reference signal port scheduled by the first downlink control information; the first downlink control information is related to the first physical downlink control channel configuration configured by the terminal or the second Corresponding to a search space group, the first physical downlink control channel configuration or the first search space group is related to the first transmission receiving point.

Correspondingly, the resource indicated by the demodulation reference signal (demodulation reference signal, DMRS) port scheduled by the first downlink control information is configured as the code indicated by the rate matching indication information carried in the second downlink control information A subset of resources indicated by a multiplexing group.

In the specific implementation, the two TRPs shown in Figure 2 send DCI to the terminal respectively, and indicate the antenna port (antenna port) in the respective DCI, and at the same time, the code division multiplexing of the code not transmitting data indicated by the antenna port (antenna port) Use groups (CDM groups without data) for puncturing (that is, do not send PDSCH on the indicated resources), and the antenna port indicated by the TRP to the terminal is the rate matching indication information.

After receiving one or more DCIs, the terminal obtains the number of DMRS CDM groups without data (number of DMRS CDM group without data) CDM groups according to the antenna port (antenna port) field of each DCI, and The resources corresponding to the CDM group are punctured, that is, it is considered that the PDSCH indicated by the DCI is not sent on these resources.

For example, as shown in Figure 9, a codeword is used as an example for illustration, assuming that TRP2 sends DCI to the terminal, the value (value) indicated in the DCI is 2, and the corresponding number of CDM groups that do not send data is 1, means that no data is sent on CDM group 0. This CDM group 0 may be used to send DMRS, or it may be occupied or scheduled by the system. In short, it is a CDM group that does not send data, so the terminal is not in the CDM Data demodulation is performed on group 0. In this embodiment, the resource indicated by the demodulation reference signal port scheduled by TRP1 to send DCI to the terminal is limited to the subset of resources corresponding to the CDM group indicated by the number of CDM groups that do not send data.

The situation of the two-code word as shown in FIG. 9 is similar and will not be repeated here.

The third embodiment can prevent one TRP from sending data information on the resource indicated by the DMRS port scheduled by another TRP, and the terminal can perform rate matching according to the CDM groups without data indicated by the transmission receiving point. , the data is not demodulated on the CDM group that does not transmit data, but the data is correctly demodulated on the other CDM groups.

If the terminal detects DCI in the resource sets configured by the two physical downlink control channel configurations (PDCCH-config), it performs the above-mentioned processing on the two PDSCHs indicated by the two DCIs. In this way, the resources used by one TRP to send the PDSCH DMRS can ensure that holes are punched in the PDSCH of another TRP.

In the first to third embodiments above, a physical downlink shared channel configuration (PDSCH-config) and a physical downlink control channel configuration (PDCCH-config) are associated with each other; that is, a physical downlink shared channel configuration corresponds to a physical downlink control channel Configuration, wherein, the configuration methods of the association relationship between PDSCH-config and PDCCH-config can be as follows:

1. Configure a bandwidth part downlink dedicated (BWP-Downlink Dedicated) parameter for the terminal, including two PDCCH-configs and two PDSCH-configs, and configure mutual associations.

2. Configuring a bandwidth part downlink (BWP-Downlink) parameter for the terminal includes two bandwidth part downlink specific parameters, and each bandwidth part downlink specific parameter includes a PDCCH-config and a PDSCH-config. At this time, the association relationship between the PDCCH-config and the PDSCH-config is reflected by the downlink dedicated parameters belonging to the same bandwidth part.

3. Configure a serving cell configuration (ServingCellConfig) parameter for the terminal that includes two bandwidth part downlink parameters, each bandwidth part downlink parameter includes a bandwidth part downlink dedicated parameter, and each bandwidth part downlink dedicated parameter includes a PDCCH-config and A PDSCH-config, at this time, the association relationship between the PDCCH-config and the PDSCH-config is reflected by the downlink parameters belonging to the same bandwidth part.

4. Configure two serving cell configuration parameters for the terminal, each serving cell configuration parameter includes a bandwidth part downlink parameter, each bandwidth part downlink parameter includes a bandwidth part downlink dedicated parameter, and the bandwidth part downlink dedicated parameter includes a PDCCH -config and a PDSCH-config, at this time, the association relationship between the PDCCH-config and the PDSCH-config is reflected by the configuration parameters belonging to the same serving cell.

The configuration of the relationship between the first resource and the second resource described in Embodiment 1 to Embodiment 3 above, in one case, the transmission receiving point configures it to the terminal through signaling, and in another case, it is predefined in the protocol. In other words, it is predefined by the protocol, and the transmission receiving point directly performs related transmission according to the relationship between the first resource and the second resource predefined by the protocol.
