[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to the Chinese patent application filed with the State Intellectual Property Office of the People's Republic of China on December 18, 2023, with application number 202311751848.3 and application name "A Communication Method and Device", the entire contents of which are incorporated by reference into this application. Technical Field

[0003] The present application relates to the field of communication technology, and in particular to a communication method and device. Background Art

[0004] To improve coverage and reduce interference, beamforming technology is introduced. Based on beamforming technology, devices can transmit signals using multiple beams. Where possible, multi-beam spatial division transmission is supported, meaning multi-user (MU) multiplexing / transmission using multiple beams is supported. Multi-beam MU transmission can also be understood as the ability of a transmitter to communicate with multiple receivers simultaneously using multiple beams.

[0005] Improper selection of user pairs for multi-beam MU transmission can cause interference between them, leading to communication anomalies. Determining which user pairs are suitable for multi-beam MU transmission is an urgent problem that needs to be solved. Summary of the Invention

[0006] Embodiments of the present application provide a communication method and apparatus for determining user pairs capable of multi-beam MU transmission to reduce communication anomalies.

[0007] To achieve the above objectives, the present invention adopts the following technical solutions:

[0008] In a first aspect, embodiments of the present application provide a communication method that can be performed by a first communication device. The first communication device can be a combination of components, parts, etc. used to implement the functions of a terminal device. For example, the first communication device is a terminal device, or the first communication device is a unit / module, circuit, or chip within the terminal device. The method provided in the first aspect is described below using the first communication device as an example, wherein the terminal device itself is the first communication device.

[0009] The communication method includes: a terminal device receives first information, where the first information is used to indicate a first threshold and a second threshold; and the terminal device sends N measurement results out of M measurement results. The M measurement results are results obtained by measuring reference signals received based on M measurement resources, and one measurement resource corresponds to one reference signal. The N measurement results include a first measurement result, where the signal strength of the first measurement result is the largest among the M measurement results. Both M and N are integers greater than 1. The signal strength corresponding to the first measurement result is greater than or equal to the first threshold, and the difference between the signal strengths corresponding to the remaining N-1 measurement results in the N measurement results and the signal strength corresponding to the first measurement result is greater than or equal to the second threshold.

[0010] The first threshold may be a signal strength threshold. If the signal strength corresponding to the measurement result of a resource is greater than the first threshold, the communication quality of the resource may be considered to be good. If the difference between the signal strengths corresponding to the measurement results of two resources is large, it may be considered that the interference between the two resources is low or even non-existent. In this method, the terminal device reports the measurement results to the network device based on the first threshold and the second threshold. For example, the terminal device reports to the network device a first measurement result whose signal strength is greater than or equal to the first threshold, and N-1 measurement results whose signal strength has a difference with the signal strength corresponding to the first measurement result greater than or equal to the second threshold. In this way, the resources corresponding to the first measurement result and the N-1 measurement results are used as candidate resources for MU pairing (also called candidate service resources), which allows the network device to identify resources with better communication quality and resources with lower interference to the resources, thereby allowing the network device to determine more suitable multiple terminal devices for MU transmission, reducing communication anomalies. Moreover, compared to the terminal device reporting the measurement results of all resources, the amount of data reported by each terminal device can be reduced, reducing resource overhead.

[0011] In one implementation, the N measurement results are a first measurement result and a second measurement result. The second measurement result is a measurement result with the highest signal strength among the T measurement results, the T measurement results belong to the M measurement results, and differences between the signal strengths corresponding to the T measurement results and the signal strength corresponding to the first measurement result are all greater than or equal to a second threshold, where T is a positive integer.

[0012] In this method, the N-1 measurement results are second measurement results, i.e., the measurement result having the highest signal strength among the T measurement results whose difference between the signal strength and the signal strength corresponding to the first measurement result is greater than or equal to a second threshold. Using the resource corresponding to the second measurement result as a candidate service resource for the terminal device can improve the probability of MU pairing, compared to using only the first measurement result as a candidate service resource for the terminal device.

[0013] In one implementation, the first information is further used to indicate one or more of the following: M measurement resources, a value of N, or a first resource set, where the first resource set includes M measurement resources.

[0014] In one implementation, the method further includes: the terminal device receives second information, where the second information is used to indicate the value of the first resource set and / or N, and the first resource set includes M measurement resources.

[0015] In a second aspect, embodiments of the present application provide a communication method that can be performed by a first communication device. The first communication device can be a combination of components, parts, etc. used to implement the functions of a terminal device. For example, the first communication device is a terminal device, or the first communication device is a unit / module, circuit, or chip within the terminal device. The method provided in the second aspect is described below using the first communication device as an example of the terminal device itself.

[0016] The communication method includes: a terminal device receiving first information, where the first information is used to indicate a first threshold; and the terminal device sending N measurement results out of M measurement results. The M measurement results are results obtained by measuring reference signals received based on M measurement resources, where one measurement resource corresponds to one reference signal. The N measurement results include a first measurement result. The signal strength corresponding to the first measurement result is less than or equal to the first threshold, and the N measurement results are the first N measurement results in the M measurement results sorted from largest to smallest according to signal strength. Both M and N are integers greater than 1.

[0017] The first threshold may be a signal strength threshold. In this method, when the signal strength corresponding to the first measurement result is less than or equal to the first threshold, the terminal device still reports N measurement results with greater signal strength to the network device, so that the network device can determine multiple terminal devices that are more suitable for MU transmission, thereby reducing communication anomalies.

[0018] In one implementation, the first information is further used to indicate one or more of the following: M measurement resources, a value of N, or a first resource set, where the first resource set includes M measurement resources.

[0019] In one implementation, the method further includes: the terminal device receives second information, where the second information is used to indicate the value of the first resource set and / or N, and the first resource set includes M measurement resources.

[0020] In a third aspect, embodiments of the present application provide a communication method that can be performed by a first communication device. The first communication device can be a combination of components, parts, etc. used to implement the functions of a terminal device. For example, the first communication device is a terminal device, or the first communication device is a unit / module, circuit, or chip within the terminal device. The method provided in the third aspect is described below using the first communication device as an example of the terminal device itself.

[0021] The communication method includes: a terminal device receives third information and sends fourth information. The third information is used to indicate a first threshold and a second resource set. The second resource set includes S resources for interference measurement, and S is an integer greater than or equal to 1. The fourth information indicates Q measurement results among P measurement results. The P measurement results are the results obtained by measuring the reference signals received based on the P measurement resources. One measurement resource corresponds to one reference signal. The Q measurement results include a first measurement result, and the first measurement result has the largest signal strength among the P measurement results. P and Q are both integers greater than 1. The signal strength corresponding to the first measurement result is greater than or equal to the first threshold. The fourth information includes S values. The i-th value among the S values ​​is the difference between the i-th measurement result and the first measurement result among the S measurement results. The S measurement results belong to the Q measurement results.

[0022] The first threshold may be a signal strength threshold. In this method, when the signal strength corresponding to the first measurement result is greater than or equal to the first threshold, the terminal device reports the first measurement result and S values ​​to the network device, and the network device performs MU pairing according to the S values. The S values ​​correspond to the measurement results of S resources (i.e., interference resources), so the network device can determine the resources that interfere with the service beam through the S values, thereby determining the resources that are not suitable for MU transmission. Compared to the case where the network device performs MU pairing using the service beam of each terminal device as a candidate resource, it can reduce interference between multiple users of the determined MU transmission and reduce communication anomalies. In addition, based on reporting the first measurement result and S values, the terminal device can reduce the amount of data reported by each terminal device and reduce resource overhead compared to the case where the terminal device reports the measurement results of all resources.

[0023] In one implementation, S is less than Q-1, and the Q measurement results further include R measurement results, where R is the difference between Q-1 and S. If the number of interfering resources is small, the terminal device may further report measurement results of more measurement resources so that the network device can obtain measurement results of more resources and determine a more appropriate MU pairing.

[0024] In one implementation, the R measurement results are the first R measurement results, sorted in descending order of signal strength, from the P measurement results excluding the first measurement result. In this solution, the terminal device preferentially reports the R measurement results with stronger signal strengths. Thus, using the R measurement results as candidate service resources for the terminal device can improve the probability of MU pairing compared to using only the first measurement result as a candidate service resource for the terminal device.

[0025] In one implementation, when the second resource set fails, the Q measurement results are the first Q measurement results from the P measurement results, sorted by signal strength in descending order. If the second resource set fails, the terminal device defaults to reporting the first Q measurement results from the P measurement results, sorted by signal strength in descending order. This allows the network device to use the resources corresponding to the Q measurement results as candidate service resources, ensuring good communication quality.

[0026] In one implementation, the third information is further used to indicate one or more of the following: P measurement resources, a value of Q, or a first resource set, where the first resource set includes P measurement resources.

[0027] In one implementation, the method further includes: the terminal device receives fifth information, where the fifth information is used to indicate the value of the first resource set and / or Q, and the first resource set includes P measurement resources.

[0028] In a fourth aspect, embodiments of the present application provide a communication method that can be performed by a first communication device. The first communication device can be a combination of components, parts, etc. used to implement the functions of a terminal device. For example, the first communication device is a terminal device, or the first communication device is a unit / module, circuit, or chip within the terminal device. The method provided in the fourth aspect is described below using the first communication device as an example of the terminal device itself.

[0029] The communication method includes: the terminal device receives third information and sends fourth information. The third information is used to indicate a first threshold and a second resource set, the second resource set including S resources for interference measurement, and S is an integer greater than or equal to 1. The fourth information indicates Q measurement results among P measurement results, the P measurement results are the results obtained by measuring the reference signals received based on the P measurement resources, and one measurement resource corresponds to one reference signal. The Q measurement results include a first measurement result, which has the largest signal strength among the P measurement results, and P and Q are both integers greater than 1. The signal strength corresponding to the first measurement result is less than or equal to the first threshold, and the fourth information includes Q measurement results, which are the first Q measurement results among the P measurement results sorted from large to small according to signal strength.

[0030] The first threshold may be a signal strength threshold. In this method, when the signal strength corresponding to the first measurement result is less than or equal to the first threshold, the terminal device will still report Q measurement results with greater signal strength to the network device, so that the network device can determine multiple terminal devices that are more suitable for MU transmission, thereby reducing communication anomalies.

[0031] In one implementation, the third information is further used to indicate one or more of the following: P measurement resources, a value of Q, or a first resource set, where the first resource set includes P measurement resources.

[0032] In one implementation, the method further includes: the terminal device receives fifth information, where the fifth information is used to indicate the value of the first resource set and / or Q, and the first resource set includes P measurement resources.

[0033] In a fifth aspect, embodiments of the present application provide a communication method that can be performed by a second communication device. The second communication device can be a combination of components, parts, etc. used to implement the functions of a network device. For example, the second communication device is a network device, or the second communication device is a unit / module, circuit, or chip within the network device. The method provided in the fifth aspect is described below using the second communication device being the network device itself as an example.

[0034] The communication method includes: a network device sends first information and receives N measurement results. The first information is used to indicate a first threshold and a second threshold. The N measurement results belong to M measurement results, and the M measurement results are obtained by measuring reference signals received based on M measurement resources, and one measurement resource corresponds to one reference signal. The N measurement results include a first measurement result, which has the highest signal strength among the M measurement results. M and N are both integers greater than 1. The signal strength corresponding to the first measurement result is greater than or equal to the first threshold, and the difference between the signal strength corresponding to the remaining N-1 measurement results in the N measurement results and the signal strength corresponding to the first measurement result is greater than or equal to the second threshold.

[0035] In one implementation, the N measurement results are a first measurement result and a second measurement result. The second measurement result is a measurement result having the highest signal strength among the T measurement results, the T measurement results belong to the M measurement results, and differences between signal strengths corresponding to the T measurement results and signal strengths corresponding to the first measurement result are all greater than or equal to a second threshold.

[0086] The technical solutions provided in the embodiments of the present application can be applied to communication systems related to the 3rd Generation Partnership Project (3GPP), such as the Long Term Evolution (LTE) communication system, the sixth generation (5G) mobile communication system, or can also be applied to other next-generation mobile communication systems, such as the sixth generation (6G) communication system, or other similar communication systems. Other similar communication systems may include wireless fidelity (WIFI), vehicle to everything (V2X), Internet of Things (IoT) system, narrowband Internet of Things (NB-IoT) system, and the like.

[0087] Please refer to Figure 1, which shows a communication system applicable to an embodiment of the present application. The communication system includes a radio access network 100 and a core network 200. Optionally, the communication system may also include the Internet (Figure 1 takes this as an example).

[0088] The wireless access network 100 may include at least one network device and at least one terminal device. For example, the wireless access network 100 includes two network devices 110a and 110b and terminal devices 120a through 120j. The network architecture shown in FIG1 is merely illustrative, and the number of terminal devices and / or network devices may be fewer or greater. The communication system described in the embodiments of the present application is intended to more clearly illustrate the technical solutions of the embodiments of the present application and does not constitute a limitation on the communication systems to which the embodiments of the present application are applicable. For example, the communication system may also include other devices, such as wireless relay devices and wireless backhaul devices, which are not shown in FIG1. ​​Persons skilled in the art will appreciate that as network architecture evolves, the technical solutions provided in the embodiments of the present application will remain applicable to similar technical problems. When applying the technical solutions of the embodiments of the present application to other communication systems, the devices, components, and modules in the embodiments may be replaced with corresponding devices, components, and modules in other communication systems without limitation.

[0089] In the embodiments of the present application, the network device refers to a radio access network (RAN) device. The RAN may be a 3GPP-related cellular system, such as a 5G / new radio (NR) mobile communication system, or a future-oriented evolution system (such as a 6G mobile communication system). The RAN may also be an open access network (open RAN, O-RAN or ORAN), a cloud radio access network (CRAN), or a virtualized RAN (vRAN). The RAN may also be a communication system that is a fusion of two or more of the above systems. The RAN device may also be referred to as a RAN node, a RAN entity, or an access node.

[0090] In one possible scenario, a RAN node can be a base station, an evolved NodeB (eNodeB), an access point (AP), a transmission reception point (TRP), a next-generation NodeB (gNB), a next-generation base station in a 6G mobile communication system, or a base station in a future mobile communication system. A RAN node can be a macro base station, a micro base station, an indoor station, a relay node, a donor node / host node, or a wireless controller. A RAN node can also be a server, a wearable device, a vehicle, or an onboard device. For example, a RAN node in V2X technology can be a roadside unit (RSU).

[0091] In another possible scenario, the RAN node may be a module or unit that performs part of the functions of the base station; or multiple RAN nodes collaborate to assist terminal devices in achieving wireless access, and different RAN nodes respectively perform part of the functions of the base station. For example, the RAN node may be a centralized unit (CU), a distributed unit (DU), or a radio unit (RU). The functions of the CU may be implemented by one entity, or by different entities. For example, the functions of the CU may be further divided, that is, the control plane and the user plane may be separated and implemented by different entities, namely the control plane CU entity (i.e., CU-control plane (CP) entity) and the user plane CU entity (i.e., CU-user plane (UP) entity). The CU-CP entity and the CU-UP entity may be coupled with the DU to jointly perform the functions of the RAN node. The CU and DU may be set separately, or may be included in the same network element, such as the baseband unit (BBU).

[0092] In different systems, CU (or CU-CP and CU-UP), DU or RU may also have different names, but those skilled in the art can understand their meanings. For example, in the ORAN system, CU may also be called O-CU (Open CU), DU may also be called O-DU, CU-CP may also be called O-CU-CP, CU-UP may also be called O-CU-UP, and RU may also be called O-RU. For the convenience of description, this application uses CU, CU-CP, CU-UP, DU and RU as examples for description. Any unit of CU (or CU-CP, CU-UP), DU and RU in this application can be implemented by a software module, a hardware module, or a combination of a software module and a hardware module.

[0093] The CU and DU can be configured according to the protocol layer functions of the wireless network they implement: for example, the CU is configured to implement the functions of the packet data convergence protocol (PDCP) layer and the protocol layers above it (such as the radio resource control (RRC) layer and / or the service data adaptation protocol (SDAP) layer, etc.); the DU is configured to implement the functions of the protocol layers below the PDCP layer (such as the radio link control (RLC), the media access control (MAC) layer, and / or the physical (PHY) layer, etc.). For another example, the CU is configured to implement the functions of the protocol layers above the PDCP layer (such as the RRC layer and / or the SDAP layer), and the DU is configured to implement the functions of the PDCP layer and the protocol layers below it (such as the RLC layer, the MAC layer, and / or the PHY layer, etc.). For a detailed description of the above-mentioned protocol layers, please refer to the relevant technical specifications of 3GPP or the technical specifications of other applicable communication protocols. The above division of the processing functions of the CU and DU according to the protocol layer is only an example, and can also be divided in other ways, which is not limited by this application. For example, in one design, the CU or DU can also be divided into parts with partial processing functions of the protocol layer. In one design, part of the RLC layer functions and the functions of the protocol layers above the RLC layer are set in the CU, and the remaining functions of the RLC layer and the functions of the protocol layers below the RLC layer are set in the DU.

[0094] In the embodiments of the present application, the device for implementing the functions of the network device can be the network device itself, or a device that can support the network device to implement the functions, such as a chip system or a combination of devices or components that can implement the functions of the network device, and the device can be installed in the network device. The embodiments of the present application do not limit the specific technology and specific device form used by the network device.

[0095] In the embodiments of the present application, any device that can communicate data with a base station can be considered a terminal device. Terminal devices are also referred to as terminals, terminal devices, user equipment (UE), mobile stations, or mobile terminals. Terminal devices can be widely used in various scenarios. For example, terminal devices can be: mobile phones, computers, mobile internet devices (MIDs), wearable devices, virtual reality (VR) devices, augmented reality (AR) devices, stations (STAs), robotic arms, cameras, robots, vehicles, drones, helicopters, airplanes, ships, or smart home devices (such as TVs, air conditioners, sweepers, speakers, set-top boxes), relays, customer premise equipment (CPEs), smart cars (smart cars or intelligent cars), roadside units (RSUs), etc. Terminal devices can also be terminal devices in IoT systems, such as water meters, electricity meters, etc.

[0096] The various terminal devices introduced above, if located on a vehicle (for example, placed / installed in a vehicle), can be considered as vehicle-mounted terminal devices. The vehicle-mounted terminal device can be an on-board module, on-board module, on-board component, on-board chip or on-board unit built into the vehicle as one or more components or units, and the vehicle can implement the method of the present application through the built-in on-board module, on-board module, on-board component, on-board chip or on-board unit. The on-board terminal device can be a complete vehicle device, an on-board module, a vehicle, an on-board unit (OBU), a roadside unit (RSU), a vehicle-mounted system (or a vehicle-mounted sending unit) (telematics box, T-box), a chip or a system on chip (SOC), etc. The above chip or SOC can be installed in a vehicle, OBU, RSU or T-box.

[0097] In the embodiments of the present application, the device for implementing the functions of the terminal device can be the terminal device itself, or a device capable of supporting the terminal device in implementing the functions, such as a chip system or a combination of devices or components capable of implementing the functions of the terminal device, which can be installed in the terminal device. The embodiments of the present application do not limit the specific technology and specific device form used by the terminal device.

[0098] The fifth generation mobile communication system (5G) supports beamforming technology. A beam can be understood as a spatial filter or spatial parameters. The beam used to send signals can be called a transmission beam (Tx beam), a spatial domain transmit filter, or spatial transmit parameters (spatial Tx parameters). A transmit beam can also refer to the distribution of signal strength in different directions in space after the signal is transmitted by the antenna. From this perspective, a transmit beam can also be a spatial transmission angle (such as azimuth, zenith) or a spatial transmission angle range (such as azimuth center angle and offset, azimuth uncertainty, azimuth protection range, zenith center angle and offset, zenith angle uncertainty, zenith angle protection range), etc. Correspondingly, a beam used to receive signals can be called a reception beam (Rx beam), a spatial domain receive filter, or spatial receive parameters (spatial Rx parameters). The receive beam can also refer to the signal strength distribution of wireless signals received from an antenna in different spatial directions. From this perspective, the receive beam can also be a spatial receive angle (such as azimuth and zenith) or a spatial receive angle range (such as azimuth center angle and offset, azimuth uncertainty, azimuth protection range, zenith center angle and offset, zenith angle uncertainty, and zenith angle protection range).

[0099] Beamforming technology is also known as beamforming technology, and can be specifically referred to as digital beamforming, analog beamforming, or hybrid digital / analog beamforming. Based on beamforming technology, a device may transmit signals using multiple beams. To do this, the transmitter and receiver must use specifically paired beams to achieve maximum beamforming gain between the transmit and receive beams. The beam pair link (BPL) between the transmitter and receiver, or the pairing between the transmit and receive beams, can also be referred to as the pairing between the spatial transmit filter and the spatial receive filter.

[0100] A beam pairing process between a transmitter and a receiver: the transmitter sends a reference signal by beam scanning and polls on multiple beams with different directivities; the receiver can also form receiving beams corresponding to different spatial directions and directivities by beam forming, and can poll on multiple beams with different directivities to receive reference signals through beams with different directivities. During the process, the receiver can perform measurements based on the received reference signals and report the measurement results to the transmitter to determine the beam pairing relationship between the transmitter and the receiver. For example, the receiver can report a reference signal resource with a larger reference signal receiving power (RSRP) to the transmitter, so that the transmitter determines the beam pairing relationship with the receiver based on the reference signal resource with a larger RSRP.

[0101] For example, if the transmitting end is a network device and the receiving end is a terminal device, the network device configures a measurement resource set for the terminal device. This measurement resource set includes multiple beams and a reporting quantity F. These multiple beams are the measurement resources, where F is a positive integer. The reporting quantity refers to the number of measured resources that the terminal device needs to report. The terminal device measures the multiple measurement resources and obtains measurement results for each measurement resource. These measurement results can be RSRP. The terminal device sorts the obtained measurement results from high to low and reports the first F measurement results to the network device. The network device determines the final beam pairing with the terminal device based on these F measurement results. For example, the network device selects the beam corresponding to the measurement result above the RSRP threshold from the F measurement results as the serving beam to achieve higher communication quality. The terminal device reports at least one measurement result to the network device in a differential manner. For example, if the terminal device reports four measurement results, the first measurement result reported by the terminal device and the differences between the first measurement result and the remaining three measurement results are reported by the terminal device. In NR, this difference can be up to 30dB.

[0102] Taking into account that interference is inevitable during the communication process, the network device can be configured with at least one channel measurement resource and at least one interference measurement resource. Among them, one channel measurement resource corresponds to one interference measurement resource, and the channel measurement resource and the interference measurement resource are configured through semi-static signaling. The terminal device measures the channel measurement resource and the interference measurement resource to obtain a measurement result, which can be a signal to interference plus noise ratio (SINR). The terminal device reports the measurement result to the network device in a differential manner. The terminal device can report the measurement result that is higher than the SINR threshold to the network device, so that the SINR of the beam finally paired between the network device and the terminal device is higher, so as to obtain higher communication quality. This process requires RRC reconfiguration to configure the measurement resource pair, and the delay is relatively large.

[0103] In possible scenarios, multi-beam space division transmission is supported, that is, multi-beam MU multiplexing / transmission is supported. Multi-beam MU transmission can also be understood as the transmitter can communicate with multiple receivers through multiple beams at the same time. For example, please refer to Figure 2, which is a schematic diagram of multi-beam MU transmission provided in an embodiment of the present application. Figure 2 takes the example where the transmitter is a network device and the receiver includes terminal devices 1 to 4. Among them, terminal devices 1 to 4 correspond one to one to beams 1 to 4. For example, the network device communicates with terminal device 1 through beam 1, communicates with terminal device 2 through beam 2, and so on.

[0104] It's understandable that interference may occur between one beam and another. For example, in Figure 2, if Beam 2 interferes with Beam 1, then Terminal Devices 1 and 2 cannot perform multi-beam MU transmission. Otherwise, they will interfere with each other and cause communication anomalies. Therefore, network devices need to determine which terminal devices can perform multi-beam MU transmission. Determining which terminal devices can perform multi-beam MU transmission can also be understood as determining MU pairing.

[0105] In one implementation, the network device configures a measurement resource set for MU pairing to candidate paired terminal devices. Candidate paired terminal devices refer to multiple terminal devices that can perform multi-beam MU transmission. The measurement resource set may include the service beam corresponding to each candidate paired terminal device. Taking Figure 2 as an example, the candidate paired terminal devices are terminal devices 1 to 4, and the measurement resource set configured by the network device for these four devices includes the service beams of these four terminal devices, for example, beams 1 to 4. Each terminal device can measure beams 1 to 4, and the network device determines which terminal devices can perform multi-beam MU transmission based on the measurement results of each terminal device on beams 1 to 4.

[0106] The serving beam for each terminal device is selected by the network device based on the measurement results reported by the terminal device during the beam pairing process. For example, a terminal device measures 64 beams and reports the measurement results of four candidate beams to the network device. Typically, these four candidate beams are the first four beams among the 64 beams, sorted from highest to lowest RSRP. Continuing with the example in Figure 2, for terminal device 1, the four candidate beams are beams 1 through 4, with beam 1 having the highest RSRP. However, since each terminal device reports its own measurement results separately, and these measurement results do not involve interference measurement, the network device does not know whether beams 2 through 4 will interfere with beam 1. Therefore, using the serving beams of each terminal device as the measurement beam set for MU pairing may result in significant interference between the multiple users of the determined MU transmissions, leading to communication anomalies. If MU pairing is performed based on the measurement results of all resources reported by each terminal device, each terminal device will report a large amount of data, resulting in high resource overhead.

[0107] In view of this, a technical solution of an embodiment of the present application is provided. In an embodiment of the present application, a terminal device reports resource measurement results that meet specific conditions, which are used by a network device to perform MU pairing, so that there is less interference or even no interference between multiple users of MU transmission, thereby improving communication quality. For example, the terminal device may report a first measurement result in which the RSRP is higher than a threshold (i.e., the first threshold in this article), and at least one measurement result in which the difference between the reported RSRP and the RSRP corresponding to the first measurement result is higher than a threshold (i.e., the second threshold in this article). When the RSRP of a beam is higher than the first threshold, it can be considered that the communication quality of the beam is good; when the difference between the RSRP corresponding to one beam and the RSRP corresponding to another beam is large, it can be considered that the interference between the two beams is low. Since the resources corresponding to the measurement results included by the terminal device include both resources with good communication quality and resources with low interference with the resources, the network device performs MU pairing based on the measurement results reported by the terminal device, and can obtain MU pairing with low interference and good communication quality, thereby reducing communication anomalies. In addition, compared to the terminal device reporting all measurement results, the terminal device only reports the resource measurement results that meet specific conditions, which can reduce resource overhead.

[0108] In an embodiment of the present application, measurement resources may include synchronization signal and physical broadcast channel (PBCH) block (synchronization signal and PBCH block, SSB) resources or channel state information reference signal (CSI-RS) resources. Measurement resources include measurement resources in the spatial domain, such as beam resources / beams. Measuring a resource refers to measuring a signal received on the resource.

[0109] In the embodiments of this application, "when," "if," and "if" all indicate that the device will perform a corresponding action under certain objective circumstances. They do not limit the time, do not require the device to perform a judgment action when implemented, and do not imply any other limitations. Unless otherwise specified, "if" and "if" are interchangeable, and "when" and "under the circumstances" are interchangeable. "When" and "if" are interchangeable.

[0110] In the embodiments of this application, words such as "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described in this application as "exemplary" or "for example" should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "exemplary" or "for example" is intended to present the relevant concepts in a concrete manner.

[0111] In the embodiments of the present application, "sending" and "receiving" indicate the direction of signal transmission. For example, "sending information to XX" can be understood as the destination of the information being XX, which can include direct sending through the air interface, and indirect sending through the air interface by other units or modules. "Receiving information from YY" can be understood as the source of the information being YY, which can include direct receiving from YY through the air interface, and indirect receiving from YY through the air interface from other units or modules. "Sending" can also be understood as the "output" of the chip interface, and "receiving" can also be understood as the "input" of the chip interface.

[0112] In other words, sending and receiving can be performed between devices, for example, between a network device and a terminal device, or can be performed within a device, for example, sending or receiving between components, modules, chips, software modules or hardware modules within the device through a bus, wiring or interface.

[0113] It is understandable that information may be processed between the source and destination of information transmission, such as coding, modulation, etc., but the destination can understand the valid information from the source. Similar expressions in this application can be understood similarly and will not be repeated.

[0114] In the embodiments of the present application, the number of nouns, unless otherwise specified, means "singular noun or plural noun", that is, "one or more". "At least one" means one or more, and "plural" means two or more. "And / or" describes the association relationship of associated objects, indicating that there may be three relationships. For example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone, where A and B can be singular or plural. The character " / " generally indicates that the previous and next associated objects are in an "or" relationship. For example, A / B means: A or B. "At least one of the following items" or similar expressions refers to any combination of these items, including any combination of single items or plural items. For example, at least one of a, b, or c means: a, b, c, a and b, a and c, b and c, or a and b and c, where a, b, c can be single or multiple.

[0115] In the embodiments of this application, ordinal numbers such as "first" and "second" are used to distinguish between multiple objects and are not used to define the size, content, sequence, timing, priority, or importance of the multiple objects. For example, the first threshold and the second threshold refer to two different thresholds, but do not indicate differences in the content, priority, or importance of the two thresholds.

[0116] The solution provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings. In the following introduction, the communication method provided by the embodiment of the present application is applied to the network architecture shown in Figure 1 or Figure 2 as an example. The network architecture and application scenarios described in the embodiment of the present application are for the purpose of more clearly illustrating the technical solution of the embodiment of the present application, and do not constitute a limitation on the technical solution provided by the embodiment of the present application. It is known to those skilled in the art that with the evolution of the network architecture and the emergence of new application scenarios, the technical solution provided by the embodiment of the present application is also applicable to similar technical problems.

[0117] The following describes the communication method provided in the embodiment of the present application by taking the communication method performed by a network device and a terminal device as an example. The steps performed by the network device can be implemented by the RAN device itself, or by components in the RAN device (such as a baseband chip, or other processing units or processor modules). For example, the network device can be the network device in Figure 1, such as the network device 110a, or it can be a chip (system) in the network device in Figure 1. The steps performed by the terminal device can be implemented by the terminal device itself, or by components in the terminal device (such as a chip, a processing unit, or a processor module). The terminal device can be the terminal device shown in Figure 1, such as the terminal device 120a, or it can be a chip (system) in the terminal device in Figure 1.

[0118] Please refer to Figure 3, which is a flow chart of the communication method 300 provided in an embodiment of the present application. Figure 3 introduces the method from the perspective of the interaction between a network device and a terminal device. It should be understood that the communication method 300 can also be implemented by other devices, such as a chip or communication device with communication functions. It should be noted that the embodiment of the present application only takes execution by a network device and a terminal device as an example, and is not limited to a network device and a terminal device. For example, the embodiment of the present application can also be executed by more terminal devices. When more terminal devices are involved, the execution process of each terminal device in these more terminal devices is the same. As shown in Figure 3, the process of the communication method 300 includes the following steps.

[0119] S301. A network device sends first information to a terminal device, where the first information is used to indicate a first threshold and a second threshold.

[0120] The first threshold may indicate that the terminal device reports a measurement result with a signal strength greater than or equal to the first threshold. If the signal strength corresponding to a measurement result is greater than or equal to the first threshold, then the terminal device may report the measurement result. The embodiment of the present application does not limit the specific name of the first threshold. For example, the first threshold may be called a signal strength threshold, such as an RSRP threshold. In the embodiment of the present application, the first threshold may be used by the network device to perform MU pairing. From this perspective, the first threshold may also be called a pairing threshold.

[0121] The second threshold may indicate a measurement result in which the difference between the signal strength reported by the terminal device and the signal strength corresponding to the first measurement result is greater than or equal to the second threshold. For example, if the difference between the signal strength corresponding to a measurement result and the signal strength corresponding to the first measurement result is greater than or equal to the second threshold, the terminal device may report the measurement result. On the contrary, if the difference between the signal strength corresponding to a measurement result and the signal strength corresponding to the first measurement result is less than the second threshold, the terminal device does not report the measurement result. Alternatively, if the difference between the signal strength corresponding to a measurement result and the signal strength corresponding to the first measurement result is greater than the second threshold, the terminal device may report the measurement result. On the contrary, if the difference between the signal strength corresponding to a measurement result and the signal strength corresponding to the first measurement result is less than or equal to the second threshold, the terminal device does not report the measurement result.

[0122] If the difference between the signal strengths corresponding to the measurement results of two resources is large, it can be considered that the interference between the two resources is low or even no interference, and the two resources can be used as candidate resources for multi-beam MU transmission; on the contrary, if the difference between the signal strengths corresponding to the measurement results of the two resources is small, it can be considered that there is interference or large interference between the two resources, and the two resources cannot be used as candidate resources for multi-beam MU transmission, otherwise it will cause communication anomalies. Therefore, the setting of the second threshold can ensure that the interference between the resources corresponding to the measurement results reported by the terminal device is low, and they are more suitable as candidate resources for MU pairing. At the same time, the setting of the second threshold can also reduce the number of measurement results reported by the terminal device, saving resource overhead. The embodiment of the present application does not limit the specific name of the second threshold. For example, the second threshold can be called an isolation threshold, an interference threshold, or a pairing threshold.

[0123] The first threshold and the second threshold can be used to instruct the terminal device to report the measurement results for the measurement resources according to the first threshold and the second threshold. For example, the first threshold and the second threshold can instruct the terminal device to report a first measurement result with a signal strength greater than or equal to the first threshold, and the difference between the reported signal strength and the signal strength corresponding to the first measurement result is greater than or equal to the measurement result of the second threshold. This can ensure that the communication quality of the resource corresponding to the measurement result reported by the terminal device is good and the interference is low. The network device can perform multi-beam MU pairing based on the measurement results reported by the terminal device to reduce communication anomalies.

[0124] The values ​​of the first threshold and the second threshold can be obtained based on historical experiments. For example, the first threshold can be -60dB, and the second threshold can be 20dB. The network device can configure the first threshold and the second threshold for the terminal device. For example, the network device can send first information to the terminal device, where the first information can indicate the first threshold and the second threshold. In response, the terminal device receives the first information and determines the first threshold and the second threshold based on the first information.

[0125] The first information may be carried in one or more of RRC, downlink control information (DCI) or MAC control element (CE). The embodiment of the present application does not limit the specific name of the first information. For example, the first information may also be called resource selection information or measurement result reporting configuration information. Optionally, the first threshold and / or the second threshold may be (pre) configured. For example, the first threshold may be preconfigured / predefined, and the second threshold may be indicated by the first information. In this case, the first information indicates the second threshold and does not indicate the first threshold. For another example, the second threshold may be preconfigured / predefined, and the first threshold may be indicated by the first information. In this case, the first information indicates the first threshold and does not indicate the second threshold.

[0126] S302: The terminal device sends N measurement results out of M measurement results to the network device, where the N measurement results are determined based on a first threshold and a second threshold. That is, the terminal device sends N measurement results out of M measurement results to the network device based on the first threshold and the second threshold.

[0127] The terminal device may report the measurement results for the measurement resources to the network device based on the first threshold and the second threshold. For ease of description, the following takes the embodiment of the present application as an example in which the terminal device reports N measurement results out of M measurement results to the network device, and takes the example in which the signal strength corresponding to the first measurement result is greater than or equal to the first threshold. It can be understood that the M measurement results correspond to M measurement resources. The measurement result corresponding to a measurement resource is the result obtained by measuring the reference signal received by the measurement resource. The N measurement results include the first measurement result, and M and N are both integers greater than 1.

[0128] The M measurement resources may be all resources in the first resource set, and the terminal device measures all resources in the first resource set to obtain M measurement results. This allows the network device to obtain sufficient resource information to perform multi-beam MU transmission pairing, so that interference between MU pairs is low or even non-existent, achieving better communication quality. The first resource set may be (pre)configured / predefined. For example, the first resource set is preconfigured / predefined; for another example, the network device may send second information to the terminal device, and the second information may indicate the first resource set. For example, the second information may include an index of the first resource set, or the second information may include an index of each resource in the first resource set. The second information may be carried in RRC signaling or MAC CE signaling. Alternatively, the network device may indicate the first resource set through the first information, that is, the first information may indicate the first threshold, the second threshold, and the first resource set; or, the first information may indicate the first threshold and the first resource set, and predefine or preconfigure the second threshold; or, the first information may indicate the second threshold and the first resource set, and predefine or preconfigure the first threshold.

[0129] In possible scenarios, it is not necessary for the terminal device to measure all resources in the first resource set. In this case, the M measurement resources are part of the resources in the first resource set, which reduces the measurement process and the amount of reported data of the terminal device, thereby reducing the processing complexity and power consumption of the terminal device. The network device can indicate the M measurement resources to the terminal device, so that the terminal device measures the M measurement resources without measuring all resources in the first resource set.

[0130] In one implementation, the network device may directly indicate M measurement resources. For example, in the case where the network device indicates M measurement resources through first information, the first information may include indexes of the M measurement resources. Of course, the network device may also indicate M measurement resources through other information. For example, the network device may also indicate M measurement resources through information X. In this case, the first threshold and the second threshold may be carried in one signaling, and the indication of the M measurement resources may be carried in another signaling. In a possible implementation, the first threshold and the second threshold may also be carried in different signaling.

[0131] The network device may also indicate that the M measurement resources are the M measurement resources in the first resource set. For example, the network device indicates the first resource set through the second information, and indicates the M measurement resources in the first resource set through the first information. The manner in which the second information indicates the first resource set is as described above. The first information indicating the M measurement resources in the first resource set includes but is not limited to the following: 1) The first information includes the index of the M measurement resources in the first resource set; 2) If the M measurement resources are a group of resources in the first resource set, the first information may include the index of the group to which the M measurement resources belong in the first resource set; 3) The first information is a bitmap of length L, where L is the number of resources included in the first resource set, 1 bit corresponds to one resource, and the M measurement resources are the resources corresponding to the bits in the bitmap with a value of "1" or "0". Of course, the network device may also indicate the M measurement resources through other information. For example, the network device may also indicate the M measurement resources in the first resource set through information Y.

[0132] The value of N may be (pre)configured / predefined. The value of N may be indicated by the first information or the second information. The M measurement results, the value of N, and the first threshold and the second threshold may be carried in one signaling or in multiple signalings.

[0133] Taking the M measurement results of all resources in the first resource set as an example, the following situations are included: A) the first resource set and the value of N are preconfigured / predefined, and the first information can indicate the first threshold and the second threshold; B) the first resource set is configured, the value of N is preconfigured / predefined, and the first information can indicate the first threshold, the second threshold and the first resource set; or the first information indicates the first threshold and the second threshold, and the second information indicates the first resource set; C) the first resource set is preconfigured / predefined, the value of N is configured, and the first information can indicate the first threshold, the second threshold and the value of N; or the first information indicates the first threshold and the second threshold, and the second information indicates the value of N.

[0134] Taking the M measurement results as part of the resources in the first resource set as an example, the following situations are included: A) the first resource set and the value of N are pre-configured / pre-defined, and the first information may indicate the first threshold, the second threshold and M measurement resources; or, the first information indicates the first threshold and the second threshold, and the second information indicates M measurement resources; B) the first resource set is configured, and the value of N is pre-configured / pre-defined, the first information may indicate the first threshold, the second threshold and M measurement resources, and the second information indicates the first resource set; C) the first resource set is pre-configured / pre-defined, and the value of N is configured, the first information may indicate the first threshold, the second threshold and the value of N; or the first information indicates the first threshold and the second threshold, and the second information indicates the value of N.

[0135] The terminal device measures M measurement resources to obtain M measurement results, and reports N of these M measurement results to the network device. Before reporting the N measurement results, the terminal device may sort the M measurement results from highest to lowest according to signal strength, and determine the measurement result corresponding to the maximum signal strength as the first measurement result. The terminal device may report N measurement results to the network device based on the first threshold and the second threshold, including the following two situations. For ease of description, the following example uses N greater than or equal to 2.

[0136] Case A: The signal strength corresponding to the first measurement result is greater than or equal to the first threshold, and the terminal device may report the first measurement result to the network device. In addition, the terminal device also reports N-1 measurement results other than the first measurement result to the network device, where the difference between the signal strength corresponding to each of the N-1 measurement results and the signal strength corresponding to the first measurement result is greater than or equal to the second threshold.

[0137] Case A can also be understood as: when the signal strength corresponding to the first measurement result is greater than or equal to the first threshold, the terminal device, in addition to reporting the first measurement result, also reports N-1 measurement results, and each of the N-1 measurement results meets a specific condition, and the specific condition is that the difference between the signal strength corresponding to the measurement result and the signal strength corresponding to the first measurement result is greater than or equal to the second threshold. Alternatively, Case A can be understood as: the terminal device reports a measurement result that meets a specific condition, and the specific condition includes: the signal strength corresponding to the first measurement result is greater than or equal to the first threshold, and the terminal device reports a measurement result; and the terminal device also reports N-1 measurement results whose signal strength and the difference between the signal strength corresponding to the first measurement result are greater than or equal to the second threshold.

[0138] Continuing with the example of Figure 2, taking terminal device 1 as an example, assuming that the terminal device measures beams 1 to 4, the signal strength corresponding to beam 1 is the largest, the difference between the signal strength corresponding to beam 2 and the signal strength corresponding to beam 1 is less than the second threshold, the difference between the signal strength corresponding to beam 3 and the signal strength corresponding to beam 1 is greater than the second threshold, and the difference between the signal strength corresponding to beam 4 and the signal strength corresponding to beam 1 is greater than the second threshold, then the terminal device reports the measurement results of beam 1, beam 3 and beam 4 to the network device.

[0139] For ease of understanding, please refer to Figure 4, which is a schematic diagram of M measurement results provided in an embodiment of the present application. The resources in Figure 4 take beams as an example, and take M=7 and N=3 as an example. As can be seen from Figure 4, the first measurement result is the measurement result of beam 0. The difference between the signal strength corresponding to the measurement results of beams 1 to beam 4 and the signal strength corresponding to the measurement result of beam 0 is less than the second threshold, and the difference between the signal strength corresponding to the measurement results of beams 5 and beam 6 and the signal strength corresponding to the measurement result of beam 0 is greater than the second threshold. The terminal device finally reports the measurement results of beams 0, beams 5 and beam 6 to the network device (such as the selected beams indicated by the dotted lines in Figure 4).

[0140] It can be understood that if the difference between the signal strengths corresponding to the measurement results of the two resources is large, for example, the difference is greater than the SINR or signal to interference ratio (SIR), it can be considered that the interference between the two resources is low, and the two resources can be used as candidate resources for multi-beam MU transmission. On the contrary, if the difference between the signal strengths corresponding to the measurement results of the two resources is small, it can be considered that there is interference when the two resources are transmitted through MU. Using the example of Figure 2, for terminal device 1, the signal strength corresponding to beam 1 is higher than or equal to the first threshold, and the difference between the signal strength corresponding to beam 2 and the signal strength corresponding to beam 1 is lower than the second threshold, it can be considered that beam 2 will interfere with beam 1. If beam 2 is the serving beam of terminal device 2, then the network device can determine that beam 1 and beam 2 cannot perform MU transmission. If the difference between the signal strength corresponding to beam 3 and the signal strength corresponding to beam 1 is greater than the second threshold, it can be considered that beam 3 will not interfere with beam 1. If beam 3 is the serving beam of terminal device 3, then the network device can determine that beam 1 and beam 3 can perform MU transmission.

[0141] In this embodiment of the present application, by setting a second threshold, interference between resources corresponding to the measurement results reported by terminal devices is relatively low, allowing them to be used as candidate resources for MU pairing. Compared to a network device using the serving beam of each terminal device as a candidate resource for MU pairing, this can reduce interference between multiple users of the determined MU transmission and alleviate communication anomalies. Furthermore, the terminal device reports N measurement results based on the first and second thresholds. Compared to the terminal device reporting measurement results for all resources, this can reduce the amount of data reported by each terminal device and reduce resource overhead.

[0142] Optionally, the N measurement results are a first measurement result and a second measurement result. The second measurement result is the measurement result with the largest signal strength among the T measurement results, the T measurement results belong to the M measurement results, and the difference between the signal strengths corresponding to the T measurement results and the signal strengths corresponding to the first measurement result is greater than or equal to the second threshold. T is an integer greater than or equal to 1. That is, in addition to reporting the first measurement result, the terminal device also reports the second measurement result with the largest corresponding signal strength among the T measurement results that meet specific conditions. Continuing with the example of Figure 4, the N measurement results may be the measurement result of beam 0 and the measurement result of beam 5. The network device may use the beam corresponding to the second measurement result as a candidate service beam to increase the probability of MU pairing.

[0143] Case B: The signal strength corresponding to the first measurement result is less than or equal to the first threshold, and the N measurement results reported by the terminal device to the network device are the first N measurement results among the M measurement results sorted in descending order of signal strength. Case B can also be understood as: the signal strength corresponding to the first measurement result is less than or equal to the first threshold, and the terminal device, in addition to reporting the first measurement result, also reports N-1 measurement results, where the N-1 measurement results are the first N-1 measurement results among the M measurement results excluding the first measurement result sorted in descending order of signal strength.

[0144] For ease of understanding, please refer to Figure 5, which is a schematic diagram of M measurement results provided in an embodiment of the present application. The resources in Figure 5 take beams as an example, and take M=7, N=3 as an example. It can be seen from Figure 5 that the first measurement result is the measurement result of beam 0. When the signal strength corresponding to the first measurement result is less than or equal to the first threshold, the terminal device also reports the measurement results of beam 1 and beam 2 to the network device, and the terminal device finally reports the measurement results of beam 0, beam 1 and beam 2 to the network device (such as the selected beam indicated by the dotted line in Figure 5).

[0145] In case B, even though the signal strength corresponding to the first measurement result is less than or equal to the first threshold, the terminal device still reports N measurement results including the first measurement result to the network device. The network device can perform multi-beam MU pairing based on the N measurement results.

[0146] It should be noted that, in case B, the first information may not indicate the second threshold. That is, the first information indicates the first threshold but does not indicate the second threshold. In this case, the terminal device obtains M measurement results, and the signal strength corresponding to the first measurement result is less than or equal to the first threshold, and the N measurement results reported by the terminal device to the network device are the first N measurement results among the M measurement results sorted from large to small according to signal strength. Alternatively, the first information indicates the first threshold and the second threshold, the terminal device obtains M measurement results, and the signal strength corresponding to the first measurement result is less than or equal to the first threshold, and the N measurement results reported by the terminal device to the network device are the first N measurement results among the M measurement results sorted from large to small according to signal strength.

[0147] By setting the first threshold and the second threshold, the communication method 300 can make the resources corresponding to the measurement results reported by the terminal device more suitable for the network device to perform multi-beam MU pairing, so that the interference between the MU pairings determined by the network device is low and the communication quality is better.

[0148] The embodiment of the present application also provides a communication method. Please refer to Figure 6, which is a flow chart of the communication method 600 provided by the embodiment of the present application. Figure 6 introduces the method from the perspective of the interaction between the network device and the terminal device. It should be understood that the communication method 600 can also be implemented by other devices, such as a chip or communication device with communication functions. It should be noted that the embodiment of the present application only takes the execution through the network device and the terminal device as an example, and is not limited to the network device and the terminal device. For example, the embodiment of the present application can also be executed by more terminal devices. When more terminal devices are involved, the execution process of each terminal device in these more terminal devices is the same. As shown in Figure 6, the process of the communication method 600 includes the following steps.

[0149] S601: A network device sends third information, where the third information indicates a first threshold and a second resource set.

[0150] Correspondingly, the terminal device receives the third information. For an introduction to the first threshold, reference may be made to the relevant content in the aforementioned communication method 300, which will not be repeated here. The third information may be carried in at least one field of one or more of RRC signaling, DCI, or MAC CE.

[0151] The second resource set is used for interference measurement or is a set of interfering resources. For example, the second resource set may be a set of beams that potentially interfere with the serving beam of the terminal device. For ease of description, the second resource set includes S resources as an example. It can be understood that S is an integer greater than or equal to 1. Accordingly, the terminal device can measure the resources in the second resource set and obtain S measurement results.

[0152] In addition, the embodiment of the present application may also configure measurement resources, such as P measurement resources, where P is an integer greater than or equal to 1. The embodiment of the present application does not limit how to indicate the P measurement resources. For example, the P measurement resources belong to a first resource set, and the first resource set may be (pre) configured or predefined. For example, the third information may also indicate the first resource set or the P measurement resources. Alternatively, the network device may send fifth information to the terminal device, and the fifth information may indicate the first resource set or the P measurement resources. When the P measurement resources are part of the resources in the first resource set, the network device may indicate the first resource set through the fifth information, and then indicate the P measurement resources in the first resource set through the third information. The terminal device may measure the P measurement resources and obtain P measurement results, with one measurement resource corresponding to one measurement result.

[0153] After measuring the P measurement resources and the S resources in the second resource set, the terminal device may report the measurement results to the network device. For example, the terminal device may report Q measurement results out of the P measurement results to the network device. The value of Q may be (pre)configured / predefined. The value of N may be indicated by the third information or by the fifth information.

[0154] S602: The terminal device sends fourth information, where the fourth information indicates Q measurement results among the P measurement results.

[0155] The terminal device obtains P measurement results, and can sort the P measurement results from large to small according to signal strength, and determine the measurement result corresponding to the maximum signal strength as the first measurement result. The terminal device can report the first measurement result to the network device, and report Q-1 measurement results other than the first measurement result. For example, the terminal device can send fourth information to the network device, and the fourth information can indicate Q measurement results out of the P measurement results. In possible implementations, the terminal device can send Q measurement results to the network device based on the first threshold, including the following two cases. For ease of description, the following takes Q being greater than or equal to 2 as an example.

[0156] Case A: The signal strength corresponding to the first measurement result is greater than or equal to the first threshold. The terminal device may report the first measurement result and Q-1 measurement results other than the first measurement result to the network device. The Q-1 measurement results include S measurement results corresponding to S resources. In this embodiment of the present application, each of the S measurement results can be represented by a difference between the first measurement result and the measurement result. For example, the fourth information may include the first measurement result and S values, and the S values ​​correspond one-to-one to the S measurement results. For example, the i-th value of the S values ​​is the difference between the i-th measurement result of the S measurement results and the first measurement result.

[0157] The terminal device may report the measurement result with low interference to the network device as a candidate resource for multi-beam MU transmission. It is understood that if the difference between the signal strengths corresponding to the measurement results of two resources is large, it can be considered that the interference between the two resources is low or even non-existent. Therefore, the difference between the measurement results corresponding to the S values ​​reported by the terminal device to the network device and the first measurement result is large. For example, the difference may be greater than or equal to the second threshold.

[0158] For ease of understanding, please refer to Figure 7, which is a schematic diagram of P measurement results provided in an embodiment of the present application. The resources in Figure 7 take beams as an example, and take P=7 and Q=3 as an example. Among beams 0 to 6 in Figure 7, the RSRP corresponding to beam 0 is the largest and higher than the first threshold. Therefore, the measurement result of beam 0 is the first measurement result. Among beams 1 to 6, the difference between the RSRP corresponding to beams 5 and beam 6 and the RSRP corresponding to beam 0 is greater than the second threshold, and the difference between the RSRP corresponding to beams 1 to beam 4 and the RSRP corresponding to beam 0 is less than the second threshold. Therefore, the terminal device can report the measurement results corresponding to beams 5 and beam 6. The terminal device finally reports the measurement result of beam 0 (the selected beam indicated by the dotted line in Figure 7) and the difference between the measurement results of beams 5 and beam 6 and the measurement result of beam 0 (the difference 1 and difference 2 indicated by the dotted line in Figure 7) to the network device.

[0159] The terminal device reports the first measurement result and S values ​​to the network device, and the network device performs multi-beam MU pairing based on the S values. Since the interference resources are taken into account, the network device can determine the resources that interfere with the service beam through the S values, thereby determining the resources that are not suitable for multi-beam MU transmission. Compared with the case where the network device uses the service beam of each terminal device as a candidate resource for MU pairing, it can reduce the interference between multiple users of the determined MU transmission and reduce communication anomalies. In addition, based on reporting the first measurement result and S values, the terminal device can reduce the amount of data reported by each terminal device and reduce resource overhead compared to the case where the terminal device reports the measurement results of all resources.

[0160] It is understood that when S=Q-1, the fourth information includes the first measurement result and S values, but does not include other measurement results. When S is less than Q-1, the fourth information includes, in addition to the first measurement result and S values, R measurement results, where R=Q-1-S.

[0161] Optionally, the R measurement results may be the first R measurement results of the P measurement results, excluding the first measurement result, sorted from highest to lowest by signal strength. That is, in addition to reporting the first measurement result and the S values, the terminal device also reports the R measurement results with relatively high signal strength. Continuing with the example of Figure 4, the N measurement results may be the measurement result of beam 0 and the measurement result of beam 5. The network device may use the beam corresponding to the second measurement result as a candidate serving beam to increase the probability of MU pairing.

[0162] Case B: the signal strength corresponding to the first measurement result is less than or equal to the first threshold, and the fourth information includes Q measurement results, where the Q measurement results are the first Q measurement results of the P measurement results sorted in descending order of signal strength.

[0163] When the signal strength corresponding to the first measurement result is less than or equal to the first threshold, the terminal device reports the first Q measurement results among the P measurement results sorted from large to small according to signal strength. Continuing with the example of Figure 5 above, assuming that P=7, Q=3, the first measurement result is the measurement result of beam 0, when the signal strength corresponding to the first measurement result is less than or equal to the first threshold, the terminal device also reports the measurement results of beam 1 and beam 2 to the network device, and the terminal device finally reports the measurement results of beam 0, beam 1, and beam 2 to the network device. In case B, although the signal strength corresponding to the first measurement result is less than or equal to the first threshold, the terminal device still reports N measurement results including the first measurement result to the network device. The network device can perform multi-beam MU pairing based on the N measurement results.

[0164] If the second resource set fails, the terminal device defaults to reporting the first Q measurement results from the P measurement results, sorted by signal strength in descending order. That is, the Q measurement results reported by the terminal device are the first Q measurement results from the P measurement results, sorted by signal strength in descending order. This allows the network device to use the resources corresponding to the Q measurement results as candidate service resources, ensuring good communication quality.

[0165] The failure of the second resource set may also be replaced by the second resource set being invalid or expired. The embodiment of the present application does not limit how the terminal device determines the failure of the second resource set. For example, in one implementation, the network device may send an indication message to the terminal device, and the indication message indicates that the second resource set is invalid. The indication message may be carried in a first indication field in the DCI, and the first indication field may be an already defined indication field or a newly defined indication field. For example, the first indication field may be a reserved field of the DCI, used to indicate whether the second resource set is invalid. Alternatively, the indication message may be carried in RRC signaling to indicate that the second resource set is invalid.

[0166] The communication method 600 takes interference resources into account, and the network device can determine resources that are not suitable for multi-beam MU transmission through the measurement results of each resource in the second resource set. Compared with the case where the network device uses the service beam of each terminal device as a candidate resource for MU pairing, the interference between multiple users of the determined MU transmission can be reduced, and communication anomalies can be reduced. In addition, based on reporting the first measurement result and S values, the terminal device can reduce the amount of data reported by each terminal device and reduce resource overhead compared to the terminal device reporting the measurement results of all resources. Moreover, compared with the process of measuring SINR, the communication method 600 does not require RRC reconfiguration, which can reduce additional measurement delay. Moreover, compared with the process of measuring SINR, the terminal device does not need to support SINR measurement and reporting, and the processing capability requirements of the terminal device are lower.

[0167] The various embodiments of this application can be combined with each other. For example, communication method 300 and communication method 600 can be combined with each other. In the embodiments provided above, the methods provided by the embodiments of this application are described using network devices and terminal devices as examples.

To implement the various functions of the methods provided by the embodiments of this application, the terminal device and the network device can include hardware structures and / or software modules, and the aforementioned functions can be implemented in the form of hardware structures, software modules, or hardware structures and software modules.
