Description

RS transmission method, user equipment and network equipment

technical field

This document relates to the field of communications, and in particular, to a reference signal (Reference Signal, RS for short) transmission method, user equipment, and network equipment.

Background technique

In the prior art, a network device sends control signaling to a user equipment (User Equipment, UE for short), notifying the UE of uplink and/or downlink resources allocated by the network device for the UE, or notifying the UE of configuration information, so that The UE performs corresponding transmission or reception.

In the prior art, different types of RS are designed for different purposes. For example, in a Long Term Evolution (Long Term Evolution, LTE for short) system, the uplink RS includes a demodulation reference signal (Demodulation Reference Signal) for demodulation. , referred to as DM RS) and the Sounding Reference Signal (Sounding Reference Signal, referred to as SRS) for measuring wireless channels, etc. The downlink RS includes DM RS for demodulation and Channel State Information Reference Signal (Channel State Information Reference Signal) for measuring wireless channels State Information-Reference Signal, referred to as CSI-RS) and so on.

In the above example, the network device sends Radio Resource Control (RRC) signaling to the UE to notify the UE of the SRS configuration (that is, after the network device sends the SRS configuration to the UE, until the next time a new SRS is sent Before the configuration of the SRS, the configuration of the SRS is always used), and the UE is dynamically triggered to send the SRS through dynamic scheduling signaling, for example, the aperiodic SRS in the LTE system; for the DM RS, the DM RS is accompanied by the data channel physical uplink shared channel ( PhysicalUplink Shared CHannel, referred to as PUSCH) is sent together, and occupies the same frequency resources as PUSCH, while PUSCH is scheduled by the dynamic scheduling signaling sent by the network device to the UE, that is, usually, the network device sends a dynamic scheduling signaling once. The PUSCH is scheduled once, and the configuration of the DM RS is notified to the UE in the dynamic scheduling signaling.

It can be seen that, for the uplink RS, the configuration scheme is more complicated, and more resources need to be occupied, resulting in a large overhead and low system efficiency. Similarly, a similar problem exists in downlink RS scheduling.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention. The following embodiments or features of the embodiments may be combined with each other without inconsistency.

In this application, the network equipment may be a base station (Base Station, referred to as BS), an access point (Access Point, referred to as AP), a remote radio equipment (Remote Radio Equipment, referred to as RRE), a remote radio port (Remote A Radio Head (RRH for short), a remote radio unit (Remote Radio Unit, RRU for short), or a relay node (Relay node). The relationship between the network device and the cell is not limited, and one network device may correspond to one or more cells, or one cell may correspond to one or more network devices. User equipment can be a mobile terminal (Mobile Terminal, referred to as MT), mobile user equipment, etc., and can communicate with one or more core networks via a radio access network (for example, Radio Access Network, referred to as RAN). User equipment can be A mobile terminal, such as a mobile telephone (or "cellular" telephone) or a computer having a mobile terminal, for example, may be a portable, pocket-sized, hand-held, computer-built-in or vehicle-mounted mobile device.

The RS in this application can be used to detect the wireless environment (including wireless channel fading, interference conditions, or Signal to Interference plus Noise Ratio (SINR), etc.) or signals for demodulation purposes, and is not used for to transmit any data. Transmission in this application includes sending or receiving, eg, transmitting an RS includes sending or receiving an RS.

This embodiment provides a method for transmitting a reference signal RS, which can reduce the signaling overhead for notifying the UE of the RS configuration, thereby improving system efficiency.

This embodiment provides a method for transmitting an RS, which can be implemented by a UE or a relay. FIG. 1 is a flowchart of a method for transmitting an RS according to an embodiment of the present invention. As shown in FIG. 1 , the method includes:

Step 101, receiving control signaling from a network device, wherein the control signaling includes orthogonal resource information;

Step 102: Determine, according to the orthogonal resource information, orthogonal resources corresponding to each of the at least two types of RSs;

Step 103, using the orthogonal resource determined in step 102 to transmit the RS corresponding to the determined orthogonal resource.

In this embodiment, the control signaling of the network device is received, and according to the orthogonal resource information in the control signaling, orthogonal resources of multiple types of RSs are determined, and the determined orthogonal resources are used to transmit the corresponding types of RSs. It can be seen that, in this embodiment, orthogonal resources of different types of RSs can be determined only according to one field of one signaling, thereby saving the overhead of notifying the RS configuration and improving the system efficiency. In addition, since the control resources carry orthogonal resource information, that is, the resources determined according to the resource information sent to each UE and the resources determined according to the resource information sent to other UEs are orthogonal. Less resources allocate orthogonal resources to different UEs, reducing interference between RSs sent by each UE.

Preferably, when the at least two types of RS are the first type of RS and the second type of RS, the first orthogonal resource corresponding to the first type of RS and the second orthogonal corresponding to the second type of RS are determined according to the orthogonal resource information. resources; then, the first type of RS may be transmitted using the first orthogonal resource, and the second type of RS may be transmitted using the second orthogonal resource.

In this embodiment, at least two types of RSs are the first type of RSs and the second type of RSs. With this embodiment, when determining orthogonal resources for the two types of RSs, it is not necessary to use different signaling for determination, thereby saving energy The overhead of notifying the RS configuration is reduced, and the system efficiency is improved.

Optionally, the above-mentioned orthogonal resource (for example: the first orthogonal resource and/or the second orthogonal resource) includes at least one of the following: a cyclic shift (Cyclic Shift, CS for short) resource, an orthogonal mask (Orthogonal Cover Code, referred to as OCC) and comb teeth. Since the RS uses orthogonal resource information, the resources corresponding to each UE and the resources corresponding to other UEs are orthogonal, so that the interference between the RSs sent by the UEs can be reduced.

Preferably, determining the first orthogonal resource corresponding to the first type of RS and the second orthogonal resource corresponding to the second type of RS according to the orthogonal resource information includes: according to the orthogonal resource information and the relationship between the first orthogonal resource The first correspondence is to determine the first orthogonal resource, and the second orthogonal resource is determined according to the second correspondence between the orthogonal resource information and the second orthogonal resource. The first correspondence and the second correspondence may be a one-to-one correspondence, a one-to-many correspondence, a many-to-one correspondence, or a many-to-many correspondence, and the correspondence may be embodied by a functional relationship , which can be implemented by presetting, for example, by presetting a corresponding relationship table, which can be implemented by looking up the table.

As a preferred way, if the above-mentioned control signaling is used for uplink scheduling, the above-mentioned orthogonal resources are CS resources, and the above-mentioned orthogonal resource information includes CS number information n_CS, then according to the orthogonal resource information and For the first correspondence between the information of the first orthogonal resource, determining the first orthogonal resource may be: determining the CS number of the first orthogonal resource as: and determining the first orthogonal resource according to the CS number of the first orthogonal resource; and/or, determining the first orthogonal resource according to the second functional relationship between the information of the orthogonal resource and the information of the second orthogonal resource The two orthogonal resources may be: determining the CS number of the second orthogonal resource as: n_CS mod N_2, and determining the second orthogonal resource according to the CS number of the second orthogonal resource. Among them, N_1 is the total number of resources of the first orthogonal resource, N_2 is the total number of resources of the second orthogonal resource, mod represents the modulo operation, Indicates a round-down operation.

The implementation process of this embodiment will be described below by taking the first type of RS as SRS and the second type of RS as DM RS as an example. Other types of RSs can implement this embodiment in a similar manner, and details are not described here. The network device sends the orthogonal code resource information n_CS to the UE. After receiving the orthogonal code resource information n_CS, the UE determines the CS value of the SRS (the first type of RS) and the CS value of the DM RS (the second type of RS) according to n_CS. ; Since the value range of the CS value of SRS and DM RS is different, it can be determined according to To determine the CS value of the SRS, determine the CS value of the DM RS according to n_C Smod N-, where N_1 is the number of available resources of the SRS (8), and N_2 is the number of available resources of the DM RS (12). UE1 assigns a CS value of 0 and assigns a CS value of 6 to UE2, then UE1 can determine according to the above formula that the CS values used by UE1 to send SRS and DM RS are both 0, and UE2 can determine according to the above formula that UE2 sends SRS and DM RS according to the above formula. The CS values used for the DM RS are 4 and 6, respectively.

The SRS can be located on the time domain symbol numbered 13 in a Transmission Time Interval (TTI), the UE determines the length N2 of the SRS sequence, and determines a base sequence with the length N2 from the base sequence group corresponding to the cell , perform cyclic shift (hereinafter referred to as cyclic shift, the length after cyclic shift is still N2), map the sequence to the corresponding comb, and then perform Inverse Discrete Fourier Transform (Inverse Discrete Fourier Transform) , referred to as IDFT) transform (the length is still N2), and finally generate a 1-symbol SRS.

The DM RS can be located on the time-domain symbols numbered 3 and 10 in a TTI. The UE determines the length N1 of the DM RS sequence transmitted on each symbol, and determines a base sequence of length N1 from the base sequence group corresponding to the cell. , perform cyclic shift (the length is still N1), and then perform IDFT transformation (the length is still N1). In particular, when the dynamic scheduling signaling can also include OCC information, the UE also needs to load the OCC on the two DM RSs in the time domain. For example, the OCC includes [+1, +1] and [+1, -1] , if the OCC allocated by the network device to the UE is [+1, -1], the UE multiplies the first DM RS in the TTI by +1 and the second DM RS by -1, and finally generates two symbol DM RS.

Therefore, when the CS values corresponding to the SRS and the DM RS are obtained by calculation, the resources used for transmitting the SRS and the DM RS can be determined in the above manner. It should be noted that the above-mentioned generation methods of SRS and DM RS are for illustrative purposes, and are not used to limit the present application, and other generation methods of SRS and DM RS can also be used in this embodiment, as long as the method needs to use orthogonal resources. information.

Since both the SRS and the DM RS have a characteristic: the larger the cyclic distance of the CS value, the better the orthogonality, so through such a design, it is ensured that both the SRS and the DM RS have good orthogonality. The cyclic distance corresponds to the mod operation, e.g. for SRS, the cyclic distance between CS values of 0 and 1 is the same as the cyclic distance between 0 and 7. Therefore, the present embodiment can reduce the interference between various types of RSs.

This embodiment of the present invention further provides another RS transmission method, and this embodiment may be implemented by a network device (for example, a base station). FIG. 2 is a flowchart of another RS transmission method according to an embodiment of the present invention. As shown in FIG. 2 , the method includes:

Step 201, determining orthogonal resources corresponding to each type of RS in at least two types of RS;

Step 202, sending control signaling including orthogonal resource information to the UE, where the orthogonal resource information is used to determine the orthogonal resource corresponding to each type of RS in the at least two types of RS;

Step 203: Use the determined orthogonal resource to transmit the RS corresponding to the determined orthogonal resource with the UE.

Preferably, the first type of RS of the UE is transmitted using the first orthogonal resource determined according to the resource information, and the second type of RS of the UE is transmitted using the second orthogonal resource determined according to the orthogonal resource information.

In this embodiment, the control signaling carrying the orthogonal resource information is sent to the UE, the first type of RS is transmitted using the first orthogonal resource determined by the orthogonal resource information, and the second type of RS is transmitted using the first orthogonal resource determined by the orthogonal resource information. The second type of RS is transmitted over resources. It can be seen that in this embodiment, it is not necessary to use different signaling to determine the orthogonal resources of different types of RSs, thereby saving the overhead of notifying the RS configuration and improving the system efficiency.

Preferably, orthogonal resources corresponding to each of the at least two types of RS are determined for each of the at least two UEs, and control signaling is sent to the at least two UEs at the same TTI, wherein the The orthogonal resource information carried in the control signaling of the UE is different from the orthogonal resource information carried in the control signaling sent to other UEs; the determined orthogonal resource is used to transmit the RS corresponding to the orthogonal resource with the corresponding UE. . For example, use the determined first orthogonal resource and the corresponding UE to transmit the first type of RS corresponding to the determined first orthogonal resource, and use the determined second orthogonal resource and the corresponding UE to transmit the first type of RS corresponding to the determined first orthogonal resource. The second type of RS corresponding to the second orthogonal resource.

Optionally, if the above-mentioned at least two UEs are the first UE and the second UE, the control signaling carrying the first orthogonal resource information is sent to the first UE in the same TTI, and the control signaling carrying the second orthogonal resource information is sent to the second UE. Control signaling of orthogonal resource information, wherein the first orthogonal resource information and the second orthogonal resource information are different; the first orthogonal resource determined according to the first orthogonal resource information is used to transmit the first UE's RS of the first type, using the first orthogonal resource determined according to the information of the second orthogonal resource to transmit the RS of the first type of the second UE, and using the second orthogonal resource determined according to the information of the first orthogonal resource resources to transmit the RS of the second type of the first UE, using the second orthogonal resource determined according to the second orthogonal resource information to transmit the RS of the second UE of the second UE, for example, using the RS according to the first orthogonal The first orthogonal resource corresponding to the resource information receives the first type of RS from the first UE, uses the first orthogonal resource determined according to the second orthogonal resource information to receive the first type of RS from the second UE, and uses the first orthogonal resource determined according to the second orthogonal resource information to receive the first type of RS from the second UE. The second orthogonal resource determined by the orthogonal resource information receives the second type of RS from the first UE, and the second orthogonal resource determined according to the second orthogonal resource information is used to receive the second type of RS from the second UE; or, using the first orthogonal resource determined according to the first orthogonal resource information to send the first type of RS to the first UE, and using the first orthogonal resource determined according to the second orthogonal resource information to send the first type of RS to the second UE, The second type of RS is sent to the first UE using the second orthogonal resource determined according to the first orthogonal resource information, and the second type of RS is sent to the second UE using the second orthogonal resource determined according to the second orthogonal resource information.

In this embodiment, the orthogonal resource information sent to each UE is different. Therefore, the first orthogonal resource and the second orthogonal resource determined by each UE according to the orthogonal resource information are also different from those determined by other UEs. When When different UEs can generate mutually orthogonal RSs by using different resources, the interference between the RSs sent by the UEs is avoided or the interference between them is approached to zero.

FIG. 3 is a method for determining orthogonal resources of a reference signal RS according to an embodiment of the present invention. As shown in Figure 3, the method includes:

Step 301, the network device sends control signaling to the UE, where the control signaling includes orthogonal resource information. The control signaling sent by the network device may be, for example, physical layer signaling (for example, dynamic scheduling signaling, a physical downlink control channel (Physical Downlink Control Channel, referred to as PDCCH) for indicating uplink transmission in the LTE system), or For high-layer signaling (for example, RRC signaling), the following mainly takes the PDCCH as an example to describe the implementation process of this embodiment.

Step 302, the UE obtains orthogonal resource information from the control signaling. Preferably, the orthogonal resource information is a field of control signaling.

Step 303, the UE determines, according to the orthogonal resource information, orthogonal resources with each type of RS in the at least two types of RSs.

Step 304, the UE and the network device use the determined orthogonal resource to transmit the RS corresponding to the determined orthogonal resource. For example, the UE uses the determined orthogonal resource to send the RS corresponding to the determined orthogonal resource to the network device, and the network device uses the determined orthogonal resource to receive the RS corresponding to the determined orthogonal resource sent by the UE; Or, the network device uses the determined orthogonal resource to send the RS corresponding to the determined orthogonal resource to the UE, and the UE receives the RS corresponding to the determined orthogonal resource sent by the network device using the determined orthogonal resource RS.

In this embodiment, the network device can transmit the orthogonal resource information of at least two types of RSs to the UE only by sending orthogonal resource information to the UE through one control signaling, thereby reducing overhead and improving system efficiency. In addition, since the control resources carry orthogonal resource information, that is, the resources determined according to the resource information sent to each UE and the resources determined according to the resource information sent to other UEs are orthogonal. Less resources allocate orthogonal resources to different UEs, reducing interference between RSs sent by each UE.

Preferably, when the at least two types of RS are the first type of RS and the second type of RS, the first orthogonal resource corresponding to the first type of RS and the second orthogonal corresponding to the second type of RS are determined according to the orthogonal resource information. Resource; use the first orthogonal resource to transmit the first type of RS, and use the second orthogonal resource to transmit the second type of RS. In this embodiment, at least two types of RSs are the first type of RSs and the second type of RSs. With this embodiment, when determining orthogonal resources for the two types of RSs, it is not necessary to use different signaling for determination, thereby saving energy The overhead of notifying the RS configuration is reduced, and the system efficiency is improved.

For example, in the uplink direction, the UE determines the first orthogonal resource for sending the first type of RS and the second orthogonal resource for sending the second type of RS according to the orthogonal resource information; The device sends the first type of RS, and uses the second orthogonal resource to send the second type of RS to the network device. Various types of RSs used in the uplink direction include: SRSs, DMRSs, and/or RSs for interference detection or SINR purposes (ie, Interference Measurement Reference Signals (IRS or IMRS for short)). The uplink RS in the prior art only includes the SRS and the DM RS, and the present embodiment also supports the IRS. Using this embodiment, the signaling overhead required for this type of uplink RS can be reduced.

Optionally, in the downlink direction, the UE determines a first orthogonal resource for receiving the first type of RS and a second orthogonal resource for receiving the second type of RS according to the orthogonal resource information; the UE uses the first orthogonal resource. The first type of RS sent by the network device is received, and the second type of RS sent by the network device is received by using the second orthogonal resource. The RS used in the downlink direction includes at least one of the following: CSI-RS, DM RS, and IRS.

In this embodiment, regardless of the uplink direction or the downlink direction, the first type of RS and the second type of RS represent any two types of RSs of different types. The first type of RS and the second type of RS are different types of RS with different purposes. For example, the first type of RS is SRS, which is used for sounding wireless channels; the second type of RS is DM RS, which is used for demodulating PUSCH. The orthogonal resource information used in this embodiment to determine the orthogonal resources of the first type of RS and the second type of RS may be the same field.

Optionally, the above-mentioned orthogonal resource (for example: the first orthogonal resource and/or the second orthogonal resource) includes at least one of the following: cyclic shift (Cyclic Shift, CS for short) resource, orthogonal mask OCC, and comb teeth. Since the RS uses orthogonal resource information, the resources corresponding to each UE and the resources corresponding to other UEs are orthogonal, so that the interference between the RSs sent by the UEs can be reduced.

In this embodiment, the RS using CS resources may be generated by performing cyclic shift and mathematical transformation on a base sequence of a certain length, where the length of the base sequence is the length of the RS. Therefore, in this embodiment, Cyclic shift is an orthogonal code resource (CS resource). In the LTE system, the process of generating the RS may include: the base station sends the CS number information n_CS to the UE, the UE obtains the final CS value k _CS according to k _CS =(n_CS+n(1)+n_PN)mod 12, and then passes base sequence Perform cyclic shift, and finally perform IDFT transformation on r(m) to generate RS. Wherein, M is the length of the base sequence, n(1) is the CS offset configured by the base station for all UEs in the cell, and n_PN is the CS variation value over time.

Preferably, the UE may determine the first orthogonal resource corresponding to the first type of RS and the second orthogonal resource corresponding to the second type of RS in the following manner: Corresponding relationship, the first orthogonal resource is determined, and the second orthogonal resource is determined according to the second corresponding relationship between the orthogonal resource information and the second orthogonal resource. The correspondence (eg, the first correspondence and/or the second correspondence) may be a functional relationship.

Optionally, the UE and the base station may also pre-store the correspondence between the orthogonal resource information and the orthogonal resources corresponding to various types of RSs, and the UE determines the orthogonal resources corresponding to the various types of RSs according to the orthogonal resource information and the correspondence. . For example, the UE and the base station store in advance the correspondence between the orthogonal resource information, the first orthogonal resource, and the second orthogonal resource, and the UE determines the first orthogonal resource and the second orthogonal resource according to the orthogonal resource information and the correspondence. Two orthogonal resources.

Through the above two preferred embodiments, the UE can determine the orthogonal resources of different types of RSs through only one signaling, thereby saving the system orthogonal resources.

Preferably, the above-mentioned first correspondence and the above-mentioned second correspondence are different. The method of determining the orthogonal resources of the RS of the first type according to the orthogonal resource information is different from the method of determining the orthogonal resources of the RS of the second type. For example, the function for determining the RS of the first type and the function for determining the orthogonal resources of the RS of the second type are different.

Due to the different uses of different types of RS, there are also differences in their design criteria. For example, in the LTE system, the minimum frequency band granularity of the uplink SRS is 4 physical resource blocks (Physical Resource Blocks, PRBs for short), and the minimum frequency band granularity of the uplink DM RS is 1 PRB. Therefore, in this embodiment, according to the same The orthogonal resource information of the first type of RS and the second type of RS are determined by different methods, so that the determined orthogonal resources can match the design of the first type of RS and the second type of RS, and more The reasonable allocation of orthogonal resources is guaranteed to a large extent.

Optionally, if the control signaling is control signaling for uplink scheduling, the orthogonal resources are CS resources, and the orthogonal resource information includes CS number information n_CS; then the UE determines that the CS number of the first orthogonal resource is: The first orthogonal resource is determined according to the CS number of the first orthogonal resource; and/or, the UE determines that the CS number of the second orthogonal resource is: n_CS mod N_2, and the second orthogonal resource is determined according to the CS number of the second orthogonal resource. resources, where N_1 is the total number of resources of the first orthogonal resource, N_2 is the total number of resources of the second orthogonal resource, mod represents the modulo operation, Indicates a round-down operation.

In the prior art, the generation methods of SRS and DM RS are similar, both of which are generated by performing a cyclic shift on a base sequence of a certain length and performing IDFT, wherein the length of the base sequence is the length of the SRS and the DM RS, Cyclic shift is an orthogonal code resource. If the network equipment allocates the same frequency band and different CS values to different UEs, the RSs sent by the two UEs are orthogonal, that is, there is no mutual interference or interference with each other. approaching 0.

In the LTE system, the network device sends the CS information n_CS_SRS of the SRS to the UE through RRC signaling, and the UE uses n_CS_SRS as the orthogonal code resource of the SRS, where the value range of n_CS_SRS is 0~7; for DM RS, the network The device sends 3 bits to the UE in the dynamic scheduling signaling to convey the CS value n_CS_DMRS, and the UE determines the orthogonal code resource of the DM RS according to the n_CS_DMRS, where the value of n_CS_DMRS ranges from 0 to 11.

In this embodiment, the network device sends the orthogonal code resource information n_CS to the UE, and after receiving the orthogonal code resource information n_CS, the UE determines the CS value of the SRS and the CS value of the DM RS according to n_CS; The value range of the CS value is different, therefore, according to To determine the CS value of the SRS, the CS value of the DMRS is determined according to n_CS mod N_2, where N_1 is the number of available resources of the SRS (8), and N_2 is the number of available resources of the DM RS (12). Allocate resources with a CS value of 0, and allocate resources with a CS value of 6 to UE2, then UE1 can determine according to the above formula that the CS values used by UE1 to send SRS and DM RS are both 0, and UE2 can determine UE2 according to the above formula. The CS values used for sending SRS and DM RS are 4 and 6, respectively. Since the cyclic shift of both SRS and DM RS has a characteristic: the larger the cyclic distance of the CS value, the better the orthogonality, and the cyclic distance corresponds to the mod operation, for example, for SRS, the CS value between 0 and 1 is between The cyclic distance of is the same as the cyclic distance between 0 and 7. Therefore, the resources of SRS and DM RS determined by the above function can ensure that both SRS and DM RS have good orthogonality.

Therefore, this embodiment can make SRSs of different UEs and DM RSs of different UEs have good orthogonality, and can ensure that the mutual interference between RSs sent by different UEs is the same for the two types of RSs. , so that the network device can obtain channel information by measuring the SRS.

In addition, an embodiment in which the first type of RS and the second type of RS are respectively SRS and DM RS are given above. Since the designs of IRS and SRS are similar, the first type of RS and the second type of RS are respectively IRS and DM RS. The embodiment of the RS, based on the same reason, the use of this embodiment can also ensure that the interference between the RSs sent by different UEs is the same for the two types of RSs. Therefore, the network device can obtain the interference or SINR by measuring the IRS. .

In addition, the above functional relationship can also be simply modified. For example, the CS number of the first orthogonal resource is added to the above function by 1, and the CS number of the second orthogonal resource can also be modified similarly.

Optionally, in the uplink direction, the first type of RS may be a sounding reference signal SRS, and the second type of RS may be a demodulation reference signal DM RS.

In this embodiment, the first type of RS is SRS, and the second type of RS is DM RS, which saves the signaling overhead of notifying the UE of SRS resources, that is, the network device does not need to send RRC signaling to the UE to notify SRS resource information.

Semi-static signaling includes broadcast signaling or RRC signaling, that is, after the network device sends the broadcast signaling or RRC signaling to the UE, the UE always uses the broadcast signaling or RRC signaling until the next time a new broadcast signaling or RRC signaling is sent. Configuration of signaling or RRC signaling. The present invention can also send orthogonal resource information to the UE through semi-static signaling.

As another embodiment of the present invention, the following examples are described here. In the LTE system, the network device sends the PDCCH to the UE, which includes OCC information to indicate the OCC allocated for the UE to receive the DM RS. With the present invention, the UE determines the first orthogonal resource for the RS of the first type and the second orthogonal resource for the RS of the second type according to an orthogonal resource information sent by the network device, thereby using the first orthogonal resource to receive the first orthogonal resource. One type of RS, the second type of RS is received using the second orthogonal resource, for example, when the control signaling is control signaling for downlink scheduling, the orthogonal resource is OCC, and the orthogonal resource information includes the OCC number information n_OCC. , the UE determines that the number of the first orthogonal resource OCC is: The UE determines that the number of the second orthogonal resource OCC is: n_OCC mod N_2, where N_1 is the total number of resources of the first orthogonal resource, N_2 is the total number of resources of the second orthogonal resource, mod represents a modulo operation, Indicates a round-down operation.

Through this embodiment, RSs sent by different UEs can be made orthogonal.

Preferably, the first type of RS is channel state information reference signal CSI-RS, and the second type of RS is DM RS.

Optionally, the first type of RS is an IRS, and the second type of RS is a DM RS.

In a preferred implementation of this embodiment, the first type of RS and the second type of RS use at least one of the same base sequence, base sequence group, sequence hopping rule, sequence group hopping rule, and CS hopping rule For example, in the transmission process of the uplink RS, the IRS and the DM RS use the same base sequence, base sequence group, sequence hopping rule, sequence group hopping rule, or CS hopping rule. During the transmission process of the downlink RS, IRS and DM RS use the same base sequence, base sequence group, sequence hopping rule, or sequence group hopping rule.

In the LTE system, usually all UEs in one cell use the same base sequence group when sending RS, and different cells use different base sequence groups. In this way, since the interference between different base sequence groups is small, the inter-cell interference is reduced. Interference between RSs. In addition, the network device can also enable the sequence hopping function or the sequence group hopping function by sending signaling to the UE, so that the DM RSs sent by the UE at different times use different base sequences or different base sequence groups, which can further Randomize the interference between the RSs in the cells (the RSs sent by the UE will be interfered by the RSs of different base sequences or base sequence groups at different times, so that the interference will not always be strong or weak, ensuring the interference level over time). The principle of CS hopping is similar to that of sequence group hopping, that is, different CSs are used for DM RSs sent by the UE at different times, which can also achieve the benefit of interference randomization.

Through this embodiment, the IRS and the DM RS can use the same base sequence, base sequence group, sequence hopping rule, sequence group hopping rule or CS hopping rule, so that if the IRS is sent before the DM RS, and the IRS Occupying the same frequency band as the DM RS, the result obtained by the network device in estimating the interference according to the IRS is similar to the interference actually received by the DM RS, and the interference can be estimated more accurately.

As another embodiment of the present invention, the first orthogonal resource is a comb tooth, and the second orthogonal resource is an OCC; the UE determines the comb tooth according to the first correspondence between the orthogonal resource information and the comb tooth; according to the orthogonal resource The second correspondence between the information and the OCC determines the OCC.

The second type of RS may be DM RS, and the first type of RS may be SRS or IRS.

The following embodiments can be used for RS transmission in the uplink direction and can also be used for RS transmission in the downlink direction.

In the uplink transmission of LTE, the network equipment can notify the UE of the OCC information, and after the UE receives the OCC information, it loads the DM RS with the OCC; however, the SRS or IRS usually has only one RS symbol in the time domain, so it cannot be used. The same method loads OCC in the time domain.

In this embodiment, the network device may send orthogonal resource information to the UE, and the UE may determine the comb teeth of the SRS or IRS according to the orthogonal resource information, and determine the OCC of the DM RS according to the orthogonal resource information. In this way, when the network device sends different orthogonal resource information to different UEs, these different UEs use different OCCs to ensure the orthogonality of DM RSs, while for SRS or IRS, different comb teeth are used to ensure orthogonality . For example, the network device sends the first orthogonal resource information to UE1, and sends the second orthogonal resource information to UE2, where the first orthogonal information may instruct UE1 to use odd comb teeth and OCC[+1,+1], The first orthogonal information may indicate that UE2 uses an even comb and OCC[+1,-1], then UE1 and UE2 use OCC[+1,+1] and OCC[+1,-1] to generate DM RSs, respectively, The odd-numbered comb teeth and the even-numbered comb teeth are respectively used to generate the SRS, thus ensuring that the two types of RSs sent by different UEs are orthogonal.

The correspondence between different OCCs and comb teeth may be preset on the UE and the network device side, or may be notified by the network device sending signaling to the UE, and the signaling may be broadcast signaling or RRC signaling. In this way, only through the OCC information, the UE can learn the OCC and the comb teeth, so as to determine the resources corresponding to different RSs.

Optionally, the above-mentioned comb teeth include at least one of the following: odd-numbered comb teeth, even-numbered comb teeth, sub-comb teeth of odd-numbered comb teeth, and sub-comb teeth of even-numbered comb teeth.

In a system, SRS and IRS have different purposes and may both need to be sent by the UE. If the UE uses all combs to transmit SRS, there is no comb resource for transmitting IRS, and vice versa. Therefore, the UE may be allocated a first comb tooth for sending SRS and a second comb tooth for sending IRS.

For the IRS, in order to keep the IRS sent by the different UEs orthogonal when the network device allocates different orthogonal resources to different UEs, different OCCs of the DM RS may correspond to different sub-comb teeth. For example, an odd-numbered comb is used to send IRS (that is, the UE sends IRS using subcarriers numbered 1, 3, 5...), if the network device sends the 1st and 2nd orthogonal resource information to UE1 and UE2, then UE1 and UE2 UE2 uses OCC[+1, +1] and OCC[+1, -1] to generate DMRS, respectively, and uses two sub-combs of odd-numbered combs to send IRS, that is, using numbers 1, 5, 9... ... and sub-carriers numbered 3, 7, 11, ... to transmit IRS, which ensures that when the IRS occupies only one comb tooth, the IRSs sent by different UEs remain orthogonal.

Preferably, the control signaling further includes a layer number indication, which is used to instruct the UE to transmit with n_layer layers; the UE determines the orthogonal resource information corresponding to each of the n_layer antenna ports according to the orthogonal resource information and the number of each layer, The first orthogonal resource corresponding to the first type of RS transmitted by each antenna port is determined according to the orthogonal resource information corresponding to each antenna port, and the second orthogonal resource transmitted by each antenna port is determined according to the orthogonal resource information corresponding to each antenna port. The second orthogonal resource corresponding to the class RS; use the determined first orthogonal resource to transmit the corresponding first class RS through the corresponding n_layer antenna ports, and use the determined second orthogonal resource to transmit the corresponding n_layer antenna port through the corresponding The second type of RS.

This embodiment can be applied to uplink or downlink MIMO scenarios. The following description will be given by taking the uplink MIMO as an example. In the prior art, the network device may send control signaling to the UE to instruct the UE to send n_layer layer data, which can improve efficiency by utilizing spatial characteristics. This embodiment extends to the multi-layer transmission scenario. For example, if the network device instructs the UE to send layer 2 data, the UE determines the CS values of the SRS and DM RS of the two antenna ports according to the orthogonal resource information, and sends them to the network device. The method for determining the CS value is not limited. For example, the orthogonal resource information includes CS number information n_CS, and the UE can determine the CS value corresponding to the two antenna ports according to n_CS as n_CSi (for example, n_CSi=(n_CS+i×N_2/n_layer) mod N_2), where i=0, 1 represents the number of the layer, and the CS values of the orthogonal resources of the first type RS corresponding to the two antenna ports are further determined as It is determined that the CS values of the orthogonal resources of the second type RS corresponding to the two antenna ports are respectively n_CSi mod N_2. The same method can be used for downlink MIMO, which is not repeated here.

Optionally, the first period during which the UE sends the first type of RS and the second period during which the UE sends the second type of RS belong to different transmission time intervals (TTIs).

The first time period and the second time period are usually preset on the side of the UE and the network device. For example, if the network device sends control signaling to the UE on the TTI numbered n, the UE sends the first type of RS on the TTI numbered n+n1. , the second type of RS is sent on the TTI numbered n+n2, where n1 and n2 are fixed values.

For example, the first period is the last symbol of the TTI numbered n+1, and the second period is the two symbols numbered 3 and 10 of the TTI numbered n+4, which is convenient for the UE to use after the arrival of the first period The interval between the first period and the second period is to process the first type of RS first, and process the second type of RS after the arrival of the second period, which can facilitate the implementation of the UE; in addition, if the first type of RS can help to adjust the PUSCH scheduling ( PUSCH and DM RS are sent in the same TTI), then the first period and the second period belong to different TTIs, that is, the first type of RS and the second type of RS are respectively sent in different TTIs, which is beneficial for the network device to receive After the RS of the first type, the scheduling of the PUSCH is adjusted according to the measurement result of the RS of the first type, so that the scheduling of the PUSCH better matches the change of the channel environment. The downlink transmission is similar and will not be repeated here.

Preferably, the above-mentioned orthogonal resource information includes at least one of the following: code orthogonal resource information and comb tooth resource information.

Usually, for the sake of convenience, the relationship between the time when the network device sends the control signaling and the time when the UE sends the RS is fixed. For example, in the LTE system, when the network device sends the control signaling at the TTI numbered n, the UE will The DM RS is sent in the TTI numbered n+4. Therefore, the orthogonal resource information in this embodiment does not include time resource information, and this embodiment has the advantage of being easy to implement.

Assuming that the first type of RS is an SRS, the second type of RS is a DM RS, and the network device sends control signaling to the UE at the TTI numbered n, the UE can send the PUSCH including the DM RS at the TTI numbered n+4, and Send the SRS at the first TTI greater than n+6 that can be used to send the SRS, wherein the control signaling may include: code orthogonal resources, and the UE uses the corresponding code resources to send the SRS and the DM RS according to the control signaling; The codes include orthogonal codes; in the uplink direction of the LTE system, as mentioned above, the code resources can be CS resources. When different UEs send DM RSs or SRSs corresponding to different CS resources on the same frequency band, the signals sent by these UEs are mutually exclusive. can be orthogonal.

Optionally, the network device sends control signaling to at least two UEs at the same TTI, wherein the orthogonal resource information carried in the control signaling sent to each of the at least two UEs is the same as the information sent to other UEs of the at least two UEs. The orthogonal resource information carried in the control signaling of the UE is different; the network device uses the first orthogonal resource determined according to the orthogonal resource information sent to each UE to transmit the first type of RS corresponding to the determined first orthogonal resource, The second type of RS corresponding to the determined second orthogonal resource is transmitted using the second orthogonal resource determined according to the orthogonal resource information sent to each UE.

For example, if the at least two UEs are the first UE and the second UE, the network device sends the control signaling carrying the first orthogonal resource information to the first UE, and sends the control signaling carrying the second orthogonal resource information to the second UE at the same TTI. The control signaling of the cross-resource information, the first orthogonal resource information and the second orthogonal resource information are different; the network device uses the first orthogonal resource determined according to the first orthogonal resource information to receive the first type RS from the first UE , using the first orthogonal resource determined according to the second orthogonal resource information to receive the first type RS from the second UE, and using the second orthogonal resource determined according to the first orthogonal resource information to receive the second RS from the first UE type RS, using the second orthogonal resource determined according to the second orthogonal resource information to receive the second type RS from the second UE; or, the network device uses the first orthogonal resource determined according to the first orthogonal resource information to the first A UE sends the first type of RS, uses the first orthogonal resource determined according to the second orthogonal resource information to send the first type of RS to the second UE, and uses the second orthogonal resource determined according to the first orthogonal resource information to the second UE. A UE sends the second type of RS, and uses the second orthogonal resource determined according to the second orthogonal resource information to send the second type of RS to the second UE.
