In systems using different wireless access technologies, names of devices having base-station functions may vary. For example, it may be called as a gNodeB or a gNB in a 5G new radio (NR) system. As the communication technology evolves, the description of “base station” may change. The network device 120 can also be a location management function (LMF).

It should be known by those skilled in the art that, with the evolution of the communication system and the emergence of new service scenarios, the technical solution provided by the embodiments of the disclosure is also applicable to similar technical problems.

The first beam is any one of the at least two beams, and the second beam is another one of the at least two beams other than the first beam.

[0065] Optionally, the method also includes sending beam report configuration information. The beam report configuration information is used to instruct the terminal to give priority to sending a beam measurement result report of a first beam group. The first beam group includes beams of different TRPs, or the first beam group includes beams of different cells, or the first beam group includes beams of the same TRP.

[0066] It is worth noting that the abovementioned step 201 can be combined with any of the above optional steps.

[0067] FIG. 4 is a flowchart of method for transmitting a beam measurement result report according to an embodiment of the disclosure. The method may be executed by both a network device and a terminal. As shown in FIG. 4, the method includes the following steps.

[0068] In step 301, the network device sends beam measurement configuration information.

[0069] The beam measurement configuration information includes reference signal resource configuration information. The reference signal resource configuration information includes at least one reference signal resource configuration set, and each reference signal resource configuration set includes N configurations of a reference signal resource. N is an integer greater than 1.

[0070] In an embodiment of the disclosure, the reference signal resource is a downlink reference signal resource, that is, a reference signal is sent by the network device and received by the terminal.

[0071] Optionally, the configurations of the reference signal resource includes at least one of the following: a reference signal identification corresponding to the reference signal resource, a time domain resource of the reference signal resource, a frequency domain resource of the reference signal resource, and the number of antenna ports of the reference signal resource.

[0072] In an embodiment of the disclosure, the reference signal resource configuration information also includes an identification of a reference signal. Optionally, the reference signal resource configuration information also includes a cell identification corresponding to the reference signal, a TRP identification corresponding to the reference signal, and so on.

[0073] Optionally, the beam measurement configuration information also includes beam report configuration information. The beam report configuration information is used to instruct the terminal to give priority to sending a beam measurement result report of a first beam group. The first beam group includes beams of different TRPs, or the first beam group includes beams of different cells, or the first beam group includes beams of the same TRP. The terminal is instructed to give priority to sending a beam measurement result report of a beam group required by the network device through the beam report configuration information, making the application more flexible.

[0074] Optionally, the network device sends the beam measurement configuration information through a radio resource control (RRC) message.

[0075] In step 302, the terminal receives the beam measurement configuration information.

[0076] In step 303, the network device provides beams in different directions through N TRPs and sends reference signals corresponding to N reference signal resources through the beams in different directions.

[0077] N is greater than 1 and N is an integer.

[0078] Optionally, the N TRPs belong to the same network device. For example, the N TRPs belong to a network device that serves a cell of the terminal. Or the N TRPs belong to different network devices. For example, some TRPs belong to the network device that serves the cell of the terminal, and some TRPs belong to a network device that serves a neighbor cell of the terminal.

[0079] Optionally, in some embodiments, each TRP contains only one panel. In other embodiments, each TRP contains multiple panels, and different panels of the same TRP can also provide beams in different directions. Therefore, the network device can use different panels to send the reference signals on different reference signal resources.

[0080] In step 303, different TRPs provide beams in different directions, and the reference signals sent on different beams are different, that is, each beam sends a reference signal corresponding to one of the N reference signal resources.

[0081] Optionally, each TRP corresponds to one cell, one cell corresponds to at least one TRP, and each cell corresponds to different TRPs. For example, a serving cell corresponds to TRP1 and TRP2, and a neighbor cell corresponds to TRP3.

[0082] In some examples, a portion of N TRPs corresponds to serving cells, and the other portion of the N TRPs corresponds to neighbor cells.

[0083] It should be noted that the embodiments of the disclosure does not limit the number of the neighbor cells, and the number of the neighbor cells can be one or more.

[0084] Optionally, the reference signal includes at least one of a synchronization signal and PBCH block (SSB), a channel state information-reference signal (CSI-RS), and a positioning reference signal (PRS).

[0085] In step 304, the terminal receives the reference signals.

[0086] In step 304, the terminal uses at least one antenna panel to receive the reference signals based on the beam measurement configuration information. In different transmission environments, for any reference signal sent by the network devices, the terminal may have one or more antenna panels receiving the reference signal, or the terminal may have no antenna panel that is capable of receiving the reference signal.

[0087] For the terminal, if the terminal receives two reference signals using different antenna panels, it indicates that the terminal supports to simultaneously transmit beams corresponding to the two reference signals. Alternatively, if the terminal receives two reference signals using the same receiving beam of the same antenna panel, it indicates that the terminal supports to simultaneously transmit beams corresponding to the two reference signals. Therefore, that the terminal supports to simultaneously transmit two beams refers to simultaneously transmitting through different antenna panels or simultaneously transmitting through the same antenna panel.

[0088] In step 305, the terminal performs beam measurement based on the received reference signals and obtains measurement results of beams corresponding the respective reference signals.

[0089] For example, a measurement result of a beam includes at least one of a layer 1-reference signal received power (L1-RSRP) and a layer 1-signal to interference plus noise ratio (L1-SINR).

[0090] After the beam measurement, the terminal may store identifications of the reference signals and the corresponding measurement results for the convenience of generating a beam measurement result report in the future.

[0091] Optionally, the measurement result of the beam also include interference indication information, which is used to indicate an interference situation between at least two beams within the same beam group.

[0092] For example, the interference indication information includes first interference indication information used to indicate an interference situation that a first beam suffers interferences including interference from a second beam, and/or second interference indication information for indicating an interference situation that the first beam suffers interferences other than the interference from a second beam. The first beam is any one of the at least two beams, and the second beam is another one of the at least two beams other than the first beam.

[0093] In some examples, both the first interference indication information and the second interference indication information are L1-SINR values. For example, the interference indication information is equal to a sum of a noise power and a value of a received power of the first beam divided by an interference value. An interference value from the second beam among interference values in the first interference indication information is greater than 0, that is, a transmission power of the network device in a direction of the second beam is greater than 0. The interference value from the second beam among interference values in in the second interference indication information is equal to 0, that is, a transmission power of the network device in the direction of the second beam is equal to 0. The interference value from the second beam is equal to a received power of the second beam.

[0094] In other examples, both the first interference indication information and the second interference indication information are interference values. For example, an interference value from the second beam among interference values in the first interference indication information is greater than 0, and the interference value from the second beam among interference values in the second interference indication information is equal to 0. The interference value from the second beam is equal to the received power of the second beam.

[0095] By including the interference indication information in the beam measurement result report, the network device can determine whether to use at least two beams within the same beam group to perform data transmission with the terminal simultaneously, and whether information content sent on the two beams are the same when using the at least two beams within the same beam group to perform data transmission with the terminal simultaneously, thereby further improving data transmission performance. For example, if the interference indication information indicates that the first beam is strongly interfered by the second beam, only the first or second beam is used for data transmission with the terminal. Alternatively, both the first beam and the second beam are used for data transmission with the terminal, and the same information content is sent to the terminal through the first beam and second beam, so as to reduce interference during data transmission.

[0096] In step 306, the terminal sends a beam measurement result report.

[0097] Optionally, a method for the terminal to send the beam measurement result report include but are not limited to periodic reporting, semi static reporting, or non-periodic reporting. Optionally, the beam measurement result report can be uplink control information (UCI). The UCI can be reported through a physical uplink control channel (PUCCH) or a physical uplink shared channel (PUSCH).

[0098] Optionally, the method for sending the beam measurement result report is indicated by the network device, for example, by a combination of one or more of RRC signaling, medium access control (MAC) signaling, and downlink control information (DCI) signaling.

[0099] In an embodiment of the disclosure, in addition to the measurement result of the beam, the beam measurement result report also includes an identification of the beam. Optionally, the identification of the beam includes an identification of a reference signal corresponding to the beam. Optionally, the identification of the beam also includes at least one of a cell identification corresponding to the beam and a TRP identification corresponding to the beam.

[0100] Optionally, the beam measurement result report also includes first indication information. In a possible embodiment, the first indication information is used to indicate beams transmitted simultaneously using filters in the same spatial domain of the terminal; and/or, the first indication information is used to indicate beams transmitted simultaneously using filters in different spatial domains of the terminal.

[0101] For example, filters in the spatial domain include a receiving filter and a sending filter. In an embodiment of the disclosure, the first indication information includes an identification of a receiving filter of the terminal corresponding to the beam. Based on the identification of the receiving filter of the terminal corresponding to the beam, the network device can identify which beam terminals support simultaneous transmission using the same receiving filter and which beam terminals support simultaneous transmission using different receiving filters.

[0102] In another possible implementation, the first indication information is used to indicate beams transmitted simultaneously using the same antenna panel of the terminal; and/or, the first indication information is used to indicate beams transmitted simultaneously using different antenna panels of the terminal.

[0103] For example, the first indication information includes an identification of an antenna panel of the terminal corresponding to the beam. Based on the identification of the antenna panel of the terminal corresponding to the beam, the network device can identify which beam terminals support simultaneous transmission using the same antenna panel and which beam terminals support simultaneous transmission using different antenna panels.

[0104] In an embodiment of the disclosure, the beam measurement result report is a group-based beam measurement result report. The group-based beam measurement result report includes a beam measurement result report of at least one beam group, with each beam group including at least two beams. Alternatively, the group-based beam measurement result report includes beam measurement result reports of at least two beam groups, with each beam group including at least one beam. That is, the beam measurement result report includes beam measurement result reports of at least two beams, and at least one beam of the at least two beams is a beam of the neighbor cell of the terminal.

[0105] In an embodiment of the disclosure, the beam measurement result report includes identifications of M reference signals and measurement values of the M reference signals. The M reference signals are M reference signals of reference signals sent through the N reference signal resources, and M is an integer greater than 0 and M is not greater than N. As mentioned above, for a certain reference signal sent by the network device, the terminal may receive the reference signal, may fail to receive the reference signal, or a received power may be too low. Therefore, the number of identifications of reference signals in the beam measurement result report is less than or equal to the number of reference signals sent by the network device, that is, M is less than or equal to N.

[0106] In some examples, the group-based beam measurement result report includes a beam measurement result report of at least one beam group, with each beam group including at least two beams. The beams within each beam group are beams that are supported to be simultaneously transmitted by the terminal.

[0107] For example, the beam measurement result report includes beam measurement results of three beam groups. Beam group 1 includes beam 11 and beam 12, beam group 2 includes beam 21 and beam 22, and beam group 3 includes beam 31. Beams 11 and 12 are beams that are supported to be simultaneously transmitted by the terminal, while beams 21 and 22 are beams that are supported to be simultaneously transmitted by the terminal.

[0108] Optionally, in this case, the beams from different beam groups are beams that are not supported to be simultaneously transmitted by the terminal.

[0109] In other examples, the group-based beam measurement result report includes beam measurement result reports of at least two beam groups. Beams from different beam groups are beams that are supported to be simultaneously transmitted by the terminal.

[0110] For example, according to an order in which measurement result reports of beams are arranged in a beam measurement result report of a corresponding beam group, beams at the same position in beam measurement result reports of different beam groups are the beams that are supported to be simultaneously transmitted by the terminal.

[0111] For example, the beam measurement result report includes beam measurement results reports for two beam groups. Beam group 1 includes beam 11 and beam 12, and beam group 2 includes beam 21 and beam 22. A beam measurement result report of beam 11 is ranked first in a beam measurement result report of a beam group to which beam 11 belongs, and a beam measurement result report of beam 21 is ranked first in a beam measurement result report of a beam group to which beam 21 belongs. Therefore, beam 11 and beam 21 are beams that are supported to be simultaneously transmitted by the terminal. Similarly, beam 12 and beam 22 are beams that are supported to be simultaneously transmitted by the terminal.

[0112] For example, there is a beam in a beam group and the terminal does not support to transmit the beam and any other beam simultaneously, thus, a beam measurement result report at a position corresponding to this beam in a beam measurement result report of other beam groups is null.

[0113] Optionally, in this case, the beams within each beam group are beams that are not supported to be simultaneously transmitted by the terminal.

[0114] In some other examples, the group-based beam measurement result report includes a beam measurement result report of at least one beam group, each beam group including beams received by the same spatial filter of the terminal, or each beam group including beams received by the same antenna panel of the terminal.

[0115] In this case, the beam measurement result report also includes second indication information. The second indication information is used to indicate beams that are supported to be simultaneously transmitted by the terminal. Optionally, the second indication information is also used to indicate beams that are not supported to be simultaneously transmitted by the terminal.

[0116] In an embodiment of the disclosure, at least two beams that are supported to be simultaneously transmitted correspond to at least two different TRPs. The at least two TRPs correspond to the same serving cell, or the at least two TRPs include a TRP corresponding to a serving cell and a TRP corresponding to a neighbor cell, or the at least two TRPs correspond to the same neighbor cell.

[0117] In step 307, the network device receives the beam measurement result report.

[0118] After receiving the beam measurement result report sent by the terminal, the network device selects appropriate beams for performing data transmission with the terminal based on at least two beams that are supported to be simultaneously transmitted by the terminal indicated in the beam measurement result report, thereby improving the throughput of the terminal.

[0119] In an embodiment of the disclosure, by including a beam measurement result report of at least one beam of the neighbor cell in the beam measurement result report, the network device can dynamically perform beam switch between beams of the serving cell and beams of the neighbor cell based on the beam measurement result report of the serving cell and the beam measurement result report of the neighbor cell in the beam measurement result report, thereby improving the data transmission performance of the terminal.

[0120] In some embodiments, at least two TRPs corresponding to the at least two beams that are supported to be simultaneously transmitted by the terminal correspond to the same serving cell. In this case, communication performance of the serving cell is good, and the network device selects a beam of the serving cell with good performance based on the beam measurement result report to perform data transmission with the terminal.

[0121] In other embodiments, the at least two TRPs corresponding to the at least two beams that are supported to be simultaneously transmitted by the terminal include a TRP corresponding to the serving cell and a TRP corresponding to the neighbor cell. In this case, the terminal is generally located at the edge of the serving cell, and located in an overlapping area of a coverage of the serving cell and a coverage of the neighbor cell. The network device uses both the beam of the serving cell and the beam of the neighbor cell to perform data transmission with the terminal, thereby improving transmission performance. Moreover, when a result obtained by performing the beam measurement by the terminal are unstable, for example, there is not much difference between a beam measurement result corresponding to the serving cell and a beam measurement result corresponding to the neighbor cell in a beam measurement result measured by a certain antenna panel of the terminal, and the beam measurement result corresponding to the serving cell are better than the beam measurement result corresponding to the neighbor cell for a period of time, while the beam measurement result corresponding to the neighbor cell are better than the beam measurement result corresponding to the serving cell for another period of time, the network device uses both the beam of the serving cell and the beam of the neighbor cell to perform data transmission with the terminal. On the one hand, it can improve the throughput of the terminal, and on the other hand, it does not require the terminal to switch back and forth between the serving cell and the neighbor cell, which is beneficial for saving signaling costs and reducing latency.

[0122] In other embodiments, the at least two TRPs corresponding to the at least two beams that are supported to be simultaneously transmitted by the terminal correspond to the same neighbor cell. In this case, the terminal is generally located at the edge of the serving cell, and the performance of data transmission through the neighbor cell is better than that through the serving cell. The terminal can switch from the serving cell to the neighbor cell. The network device that the neighbor cell belongs to can quickly use high-performance beams to perform data transmission with the terminal based on the measurement result of the beam corresponding to the neighbor cell, convenient for fast cell handover. Alternatively, the network device can use the beam of the neighbor cell to perform data transmission with the terminal, ensuring the throughput of the terminal while avoiding the ping pong effect caused by frequent handover.
