Description

Method and device for sending information and receiving information

Technical Field

The present application relates to the field of mobile communications technologies, and in particular, to a method and an apparatus for sending and receiving information.

Background

In a long term evolution (Long term evolution, LTE) system, a terminal device supports simultaneous access to two network devices, which access is referred to as dual connectivity (Dual Connectivity, DC), where one network device is a primary network device and the other network device is a secondary network device. In the evolution process of the wireless communication system, operators may deploy a fifth generation (5th generation,5G) new air interface (New radio interface, NR) system and a long term evolution (Long term evolution, LTE) system at the same time, so that in a dual-connection scenario, terminal devices support network devices that access LTE and NR simultaneously, because LTE is also called evolved universal terrestrial radio access (Evolved Universal Terrestrial Radio Access, E-UTRA), this access mode is called evolved universal terrestrial radio access and new air interface dual-connection (E-UTRA NR Dual Connectivity, EN-DC). In EN-DC mode, the network device of LTE is a primary network device and the network device of NR is a secondary network device. In yet another dual connectivity scenario, a new air interface and evolved universal terrestrial radio access dual connectivity (NR E-UTRADual Connectivity, NE-DC) may also be supported, i.e. the network device of NR is the primary network device and the network device of LTE is the secondary network device. Since both EN-DC and NE-DC terminals will access network devices of two different radio access technologies, these DC modes may also be collectively referred to as multiple radio access technology dual connectivity (Multi-RAT Dual Connectivity, MR-DC). Of course, other dual connectivity scenarios exist, such as a terminal device supporting simultaneous access to a network device of LTE and a network device of LTE, or a terminal device supporting simultaneous access to a network device of NR and a network device of NR.

However, at present, when the terminal device and the network device communicate by adopting the dual-connection technology, there is a problem that communication efficiency needs to be improved.

It should be noted that the primary network device and the secondary network device may be deployed on the same site, or may be deployed on different sites. And when the main network device and the auxiliary network device can be deployed at the same site, the main network device and the auxiliary network device can share the same set of hardware devices, and can also use different hardware devices.

The wireless terminal device may also be referred to as a system, subscriber unit (subscriber unit), subscriber station (subscriber station), mobile Station (MS), remote station (remote station), access Point (AP), remote terminal device (remote terminal), access terminal device (ACCESS TERMINAL), user terminal device (user terminal), user agent (user agent), subscriber station (subscriber station, SS), user terminal device (customer premises equipment, CPE), terminal (terminal), user Equipment (UE), mobile Terminal (MT), etc. Further, the terminal device may also be a vehicle, an in-vehicle device, or a wearable device, etc. capable of communicating with the network device.

The network device (including the primary network device and the secondary network device) is an entity for transmitting or receiving signals in the network side, and may be an access network device. The network device may be a device for communicating with a mobile device. The network device may be an Access Point (AP) in a wireless local area network (wireless local area networks, WLAN), an evolved Node B (eNB or eNodeB) in LTE, or a relay station or Access Point, or a new generation base station (generation Node B, gNodeB) in a 5G new air interface (New radio interface, NR) system, or a network device in a future evolved public land mobile network (public land mobile network, PLMN) network, etc.

In the embodiment of the application, the network equipment provides service for the cell, the terminal equipment communicates with the network equipment through the communication resource (such as frequency domain resource or spectrum resource) used by the cell, the cell can be a cell corresponding to the network equipment (such as a base station), the cell can belong to a macro base station or a base station corresponding to a small cell (SMALL CELL), the small cell can comprise a urban cell (Metro cell), a Micro cell (Micro cell), a Pico cell (Pico cell), a Femto cell (Femto cell) and the like, and the small cells have the characteristics of small coverage area and low transmitting power and are suitable for providing high-rate data transmission service. Furthermore, the network device may be other means of providing wireless communication functionality for the terminal device, as other possibilities. The embodiment of the application does not limit the specific technology and the specific equipment form adopted by the network equipment. For convenience of description, in the embodiment of the present application, a device that provides a wireless communication function for a terminal device is referred to as a network device.

In the dual connectivity scenario, there are two cell groups, namely a primary cell Group (MASTER CELL Group, MCG) and a secondary cell Group (Secondary Cell Group, SCG). Wherein the MCG comprises a primary Cell (PRIMARY CELL, PCELL), optionally one or more Secondary cells (scells), and the SCG comprises a primary Secondary Cell (Primary Secondary Cell, PSCell), optionally one or more scells. The network device managing the MCG is referred to as a primary network device, and the network device managing the SCG is referred to as a secondary network device.

In the embodiment of the present application, the primary network device is one of an LTE network device (e.g., eNB), a 5G network device (e.g., gNB), or a network device in a future communication system, and the secondary network device is also one of an LTE network device, a 5G network device, or a network device in a future communication system. And the main network device and the auxiliary network device may be network devices of the same system, for example, all are enbs, or may be network devices of different systems, for example, the main network device is an eNB, and the auxiliary network device is a gNB. The application does not limit the communication modes of the main network equipment and the auxiliary network equipment.

It should be noted that a cell may include one downlink carrier and at least one uplink carrier. In one case, a cell includes a downlink carrier and an uplink carrier, where the downlink carrier and the uplink carrier may correspond to the same frequency band, or may correspond to different frequency bands. In another case, a cell includes a downlink carrier and two uplink carriers, where the downlink carrier and one of the two uplink carriers use the same frequency band and the other uplink carrier use a different frequency band. Thus, the cell in the present application corresponds to a downlink carrier.

A cell group may include at least one cell, and typically different cell groups may be considered to correspond to different network devices, and different cells in the same cell group may correspond to the same network device or may correspond to different network devices, which is not a limitation of the present application.

In the application, the terminal equipment can simultaneously transmit signals on at least two uplink carriers. These uplink carriers may be from different cell groups or from the same cell group. When from the same cell group, the at least two uplink carriers may correspond to the same downlink carrier, i.e. belong to the same cell, or may correspond to different downlink carriers, i.e. belong to different cells.

For example, when the terminal device transmits signals on two uplink carriers simultaneously, the two uplink carriers may be referred to as a first uplink carrier and a second uplink carrier, respectively. When the first uplink carrier and the second uplink carrier in the method of the present application are from the same cell group, the method can be applied to a non-DC scenario, for example, a carrier aggregation scenario or a supplementary uplink carrier (supplementary uplink, SUL) scenario, etc. When the first uplink carrier and the second uplink carrier are from the same cell group, it may be considered that there is no cell group and only different uplink carriers.

The terminal equipment supporting MR-DC has the following three antenna configurations at present, or is called terminal equipment corresponding to three different transmitting antenna capabilities:

1) Configuration 1K 1 transmit antennas (Tx) are allocated to NR and K2 transmit antennas are allocated to LTE.

Based on this configuration 1, the terminal device can transmit signals on the uplink carrier of NR and the uplink carrier of LTE at the same time. The uplink carrier of NR is called a first uplink carrier, the uplink carrier of LTE is called a second uplink carrier, or the uplink carrier of NR is called a second uplink carrier, and the uplink carrier of LTE is called a first uplink carrier.

The number of first maximum transmitting antennas supported by the terminal device when transmitting signals on the first uplink carrier is denoted as M1, the number of second maximum transmitting antennas supported by the terminal device when transmitting signals on the second uplink carrier is denoted as M2, and the total number of maximum transmitting antennas supported by the terminal device when transmitting signals on both the first uplink carrier and the second uplink sub-carrier is denoted as M.

Taking the case that the uplink carrier of NR is referred to as the first uplink carrier and the uplink carrier of LTE is referred to as the second uplink carrier, m1=k1, m2=k2, and m=m1+m2=k1+k2.

It can be seen that in this configuration 1, the transmission antennas allocated to NR and the transmission antennas allocated to LTE are not shared.

2) And (2) allocating K3 transmitting antennas to NR, wherein K4 transmitting antennas can be shared by LTE and NR in a time division manner.

Based on this configuration 2, taking the uplink carrier of NR as the first uplink carrier and the uplink carrier of LTE as the second uplink carrier as an example, m1=k3+k4, m2=k4, m=k3+k4, and M < m1+m2.

It can be seen that in this configuration 2, the transmission antennas allocated to NR and LTE are shared between each other.

3) And 3, allocating K5 transmitting antennas to NR and K6 transmitting antennas to LTE.

The main difference between this configuration 3 and the above configuration 1 is that the values of K5 and K1 are different and/or the values of K6 and K2 are different.

Taking the case that the uplink carrier of NR is called the first uplink carrier and the uplink carrier of LTE is called the second uplink carrier, m1=k5, m2=k6, and m=m1+m2=k5+k6.

It can be seen that in this configuration 3, the transmission antennas allocated to NR and the transmission antennas allocated to LTE are not shared.

However, the terminal device communicating based on the above scenario has a need of switching between LTE uplink carrier and NR uplink carrier to transmit uplink signals, but in the prior art, because the network device cannot know the configuration of the transmitting antenna of the terminal device, the network device cannot distinguish the terminal devices with different transmitting antenna capabilities, so that the network device cannot adopt an adaptive scheduling policy for the terminal device, and the communication efficiency between the terminal device and the network device is affected.

In the present application, the transmitting antenna may also be referred to as a transmitting link, a radio frequency channel, or the like.

The values of K1, K2, K3, K4, K5, and K6 are not limited, and may be partially equal to each other.

As shown in fig. 2, a schematic diagram of an antenna configuration of a terminal device is shown. In this example:

For configuration 1, k1=1, k2=1, a total of 2 transmit antennas, and m1=1, m2=1, m=2.

For configuration 2, k3=1, k4=1, a total of 2 transmit antennas, and m1=2, m2=1, m=2.

For configuration 3, k5=2, k6=1, a total of 3 transmit antennas, and m1=2, m2=1, m=3.

The three antenna configurations correspond to three transmitting antenna capabilities of the terminal device respectively. In order to enable the network device to distinguish the terminal devices with different transmitting antenna capabilities, so as to adopt adaptive scheduling strategies for different terminal devices, the network device needs to know the transmitting antenna capabilities of the terminal devices.

The application provides a method for reporting the capacity of a transmitting antenna by a terminal device, namely the terminal device informs a network device that the terminal device supports any one of the three configurations.

As shown in fig. 3, a method for transmitting information and receiving information for a party provided by the present application includes the following steps:

in step 301, the terminal device generates a first message, the first message comprising first indication information.

The first indication information may also be referred to as transmit antenna capability indication information, or as antenna configuration indication information, etc. It should be noted that, the antenna herein may be replaced by a description of "radio frequency channel" or "radio frequency link" or "power amplifier" and the like that is related to the transmitting antenna, that is, the first indication information may also be referred to as radio frequency channel capability indication information, radio frequency link capability indication information, or power amplifier capability indication information. The present embodiment does not limit the name of the first indication information.

The first message may be, for example, a message of reporting a capability of the terminal device, where the message includes the first indication information in the present application, and may also include indication information of other capabilities, such as capability indication information of a modulation mode supported by the terminal device, capability indication information of uplink multi-antenna precoding supported by the terminal device, and so on. Therefore, the terminal device will generally determine the first indication information according to its own capability, and then encapsulate the first indication information into the first message to generate the first message.

The first indication information is used for indicating the total maximum number of transmitting antennas (denoted by M) supported by the terminal device when transmitting signals on at least two uplink carriers simultaneously, or is used for indicating whether the transmitting antennas for transmitting signals on at least two uplink carriers are shared by the terminal device.

In step 302, the terminal device sends a first message to the network device. Accordingly, the network device may receive the first message.

In step 303, the network device obtains the first indication information in the first message.

After the network device acquires the first indication information, the maximum number of transmitting antennas supported by the terminal device in total can be determined according to the first indication information. Further, the network device may determine which of the above three configurations the antenna configuration of the terminal device belongs to, based on the maximum number of transmission antennas supported by the terminal device in total.

For example, when the first indication information is used to indicate the maximum number of transmission antennas M that the terminal device supports in total when transmitting signals on the first uplink carrier and the second uplink carrier simultaneously, or to indicate whether the terminal device is shared between the transmission antennas that transmit signals on the first uplink carrier and the second uplink carrier, the network device may determine which of the three configurations the antenna configuration of the terminal device belongs to according to the first maximum number of antennas (denoted by M1) that the terminal device supports when transmitting signals on the first uplink carrier only, the second maximum number of antennas (denoted by M2) that the terminal device supports when transmitting signals on the second uplink carrier only, and the maximum number of transmission antennas M that the terminal device supports in total. The first maximum antenna number M1 supported by the terminal device only when transmitting signals on the first uplink carrier, and the second maximum antenna number M2 supported by the terminal device only when transmitting signals on the second uplink carrier may be predefined by a protocol, or may be reported to the network device in advance by the terminal device.

It should be noted that, the first uplink carrier and the second uplink carrier in this embodiment may be uplink carriers from different cell groups. For example, the first uplink carrier is from the primary cell group and the second uplink carrier is from the secondary cell group, although the reverse is also possible. Further, the cell groups corresponding to the first uplink carrier and the second uplink carrier may belong to the same radio access technology, or may correspond to different radio access technologies, for example, the first uplink carrier corresponds to LTE, and the second uplink carrier corresponds to NR, which may be the reverse. The first uplink carrier and the second uplink carrier in this embodiment may be different uplink carriers from the same cell group.

It should be noted that, the network device in the embodiment of fig. 3 may be a primary network device or a secondary network device, which is not limited by the present application.

Based on the scheme, the terminal equipment can distinguish the terminal equipment with different transmitting antenna capacities through the first indication information, so that the network equipment can adopt adaptive scheduling strategies for the terminal equipment with different transmitting antenna capacities, and the communication efficiency between the terminal equipment and the network equipment is improved.

Several different implementations of the first indication information are given below.

In the first method, the first indication information is used for indicating the total supported maximum transmitting antenna number M when the terminal equipment simultaneously transmits signals on the first uplink carrier and the second uplink carrier.

For the first method, the following two cases are classified:

In case 1, the maximum number of transmit antennas M indicated by the first indication information is smaller than the sum of the first maximum number of transmit antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier and the second maximum number of transmit antennas M2 supported by the terminal device when transmitting signals only on the second uplink carrier, i.e. M < m1+m2.

For this case 1, since M < m1+m2, the network device can determine that the antenna configuration of the terminal device should belong to configuration 2 described above. I.e. the terminal device is shared between the transmit antennas transmitting signals on the first and second uplink carriers.

In case 2, the maximum number of transmit antennas indicated by the first indication information M is equal to the sum of the first maximum number of transmit antennas M1 supported by the terminal device when transmitting signals on only the first uplink carrier and the second maximum number of transmit antennas M2 supported by the terminal device when transmitting signals on only the second uplink carrier, i.e. m=m1+m2.

For this case 2, since m=m1+m2, the network device may determine that the antenna configuration of the terminal device should belong to the above configuration 1or configuration 3, i.e., the terminal device is not shared between the transmitting antennas that transmit signals on the first uplink carrier and the second uplink carrier.

Further, the network device may determine that the antenna configuration of the terminal device is configured to be 1 or 3 according to a first maximum number of transmit antennas M1 supported by the terminal device when the terminal device transmits signals only on the first uplink carrier and a second maximum number of transmit antennas M2 supported by the terminal device when the terminal device transmits signals only on the second uplink carrier. For example, m1=k1, m2=k2, the network device determines that the antenna configuration of the terminal device is configuration 1. For another example, m1=k5, m2=k6, the network device determines that the antenna configuration of the terminal device is configuration 3.

The second method includes that the first indication information is used for indicating whether the terminal equipment is shared between transmitting antennas for transmitting signals on the first uplink carrier and the second uplink carrier.

For the second method, the following two cases are classified:

in case 1, the first indication information indicates that the terminal device is shared between transmit antennas transmitting signals on the first uplink carrier and the second uplink carrier.

For this case 1, since the terminal device is shared between the transmission antennas transmitting signals on the first uplink carrier and the second uplink carrier, the network device may determine that the antenna configuration of the terminal device should belong to the above-described configuration 2.

In case 2, the first indication information indicates that the terminal device is not shared between the transmitting antennas transmitting signals on the first uplink carrier and the second uplink carrier.

For this case 2, since the terminal device is not shared between the transmission antennas transmitting signals on the first uplink carrier and the second uplink carrier, the network device may determine that the antenna configuration of the terminal device should belong to the above-described configuration 1 or configuration 3.

For the case 1 of the first method or the case 1 of the second method, as an implementation method, the switching time when the terminal device switches between the first uplink carrier and the second uplink carrier is equal to t1, where t1 is greater than 0. For example, when the first uplink carrier and the second uplink carrier are from different cell groups and the cell groups correspond to different radio access technologies, the switching time t1 is used for the terminal device to switch the shared antenna from LTE uplink to NR uplink, or for the terminal device to switch the shared antenna from NR uplink to LTE uplink. The switching time t1 may be reported to the network device by the terminal device or may be predefined by a protocol. For example, when the switching time t1 includes one or more values, the switching time t1 may be reported to the network device by the terminal device, e.g., the switching time t1 may be one or more of 35us,120us, etc. For another example, when the switching time t1 has only one value, the terminal device may not need to report. In this scheme, the terminal device switches according to the same switching time t1, regardless of how many transmit antennas are actually used in the first uplink carrier and how many transmit antennas are actually used in the second uplink carrier.

For the case 1 of the first method or the case 1 of the second method, as a further implementation method, the switching time when the terminal device uses N1 transmit antennas to transmit signals on the first uplink carrier and uses N2 transmit antennas to transmit signals on the second uplink carrier is equal to t1, where t1 is greater than 0. Wherein n1+n2> M, n1< =k3, n2< =k4. And/or the switching time when the terminal equipment adopts N3 transmitting antennas to transmit signals on the first uplink carrier and adopts N4 transmitting antennas to transmit signals on the second uplink carrier is equal to t2, t2 is greater than or equal to 0, N3+N4< = M, N3< = K3, and N3< = K4. Here, description of the switching time t1 referring to the foregoing description, the switching time t2 may be equal to 0 or close to 0. In this scheme, when the sum of the number N1 of the transmitting antennas actually used by the terminal device on the first uplink carrier and the number N2 of the transmitting antennas actually used on the second uplink carrier is greater than M, the switching time is t1, that is, the transmitting antennas cannot simultaneously satisfy the NR transmission and the LTE transmission, so that switching is required. When the sum of the number N3 of the transmitting antennas actually used by the terminal device on the first uplink carrier and the number N4 of the transmitting antennas actually used on the second uplink carrier is less than or equal to M, the switching time is t2, that is, the transmitting antennas can simultaneously satisfy the NR transmission and the LTE transmission, so that switching is not required.

For the case 2 of the first method or the case 2 of the second method, the switching time when the terminal device switches between the first uplink carrier and the second uplink carrier is equal to t2. The switching time t2 may be equal to 0 or close to 0. In this scheme, since the terminal device does not share the transmitting antenna between the transmitting antenna of the first uplink carrier transmitting signal and the transmitting antenna of the second uplink carrier transmitting signal, the switching time is t2, that is, switching is not required.

The third method includes that the first indication information is used for indicating switching time between transmitting antennas for transmitting signals on the first uplink carrier and the second uplink carrier by the terminal equipment.

For the third method, the following two cases are classified:

In case 1, the switching time between the transmitting antennas of the terminal device indicated by the first indication information for transmitting signals on the first uplink carrier and the second uplink carrier is equal to t1, and t1 is greater than 0.

For this case 1, since the switching time is equal to t1, indicating that the terminal device is shared between the transmitting antennas transmitting signals on the first uplink carrier and the second uplink carrier, the network device may determine that the antenna configuration of the terminal device should belong to the above configuration 2.

Case 2, the switching time between the transmitting antennas of the terminal device indicated by the first indication information to transmit signals on the first uplink carrier and the second uplink carrier is equal to t2, and t2 is equal to or close to 0.

For this case 2, since the switching time is equal to t2, indicating that the terminal device is not shared between the transmitting antennas transmitting signals on the first uplink carrier and the second uplink carrier, the network device may determine that the antenna configuration of the terminal device should belong to the above configuration 1 or configuration 3.

The fourth method is that the first indication information is used for indicating the antenna configuration type of the terminal equipment.

For example, 2 bits may be used to indicate three antenna configuration types. As an example, use 00 indicates the above configuration 1,01 indicates the above configuration 2,10 indicates the above configuration 3.

For the first to fourth methods, as an implementation method, the first message in step 301 further includes second indication information, where the second indication information is used to indicate the number X of transmission antennas shared between the transmission antennas for transmitting signals on the first uplink carrier and the transmission antennas for transmitting signals on the second uplink carrier by the terminal device.

It should be noted that, the above scheme of the present application is not limited to antenna sharing between different carriers, and may also be applied to antenna sharing between different frequency bands.

The indication information reported by the existing terminal device may be multiplexed when the terminal device reports to the network device the first maximum number of antennas M1 supported by the terminal device when the terminal device transmits only the signal on the first uplink carrier. Here, the first uplink carrier refers to an uplink carrier in NR.

For example, a field supportedSRS-TxPortSwitch in the SRS-TxSwitch unit in the prior art directly indicates the capability of SRS antenna switching of the terminal device, such as 1 transmit-4 receive (1 transmit antenna and 4 receive antennas), 2 transmit-4 receive, etc., so as to indirectly indicate that the first maximum number of antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier is equal to the number of transmit antennas in the Sounding REFERENCE SIGNAL, SRS antenna switching capability.

For another example, in the prior art, the MIMO-Layers field directly indicates the maximum number of spatial Layers, such as one of Layers 1, 2, and 4, for uplink transmission by the terminal device, so as to indirectly indicate that the first maximum number of antennas M1 supported by the terminal device when transmitting signals only on the first uplink carrier is equal to the maximum number of spatial Layers.

For another example, a maxNumberSRS-Ports-PerResource field in the prior art directly indicates the maximum number of SRS Ports in one SRS resource, which may be one of 1,2 and 4, so as to indirectly indicate that the first maximum number of antennas M1 supported by the terminal device when transmitting signals on the first uplink carrier only is equal to the maximum number of SRS Ports in one SRS resource.
