[0220] In some embodiments, a core network device may be a device including one or more network elements, or may be multiple devices or device groups, each including all or part of the one or more network elements. The network element may be virtual or physical. The core network may include, for example, at least one of an Evolved Packet Core (EPC), a 5G Core Network (5GCN), and a Next Generation Core (NGC).

[0224] In New Radio (NR), especially in frequency range 2, beam-based transmission and reception are necessary to ensure coverage due to the rapid attenuation of high-frequency channels. Currently, the base station sends beam indication signaling, and the terminal uses this signaling to determine the transmit or receive beam.

[0225] Transmission configuration indication (TCI) corresponds to the downlink DCI format for scheduling or not scheduling PDSCH, that is, DCI format 1_1 / 1_2. Under normal circumstances, after the base station indicates a new beam, it needs to trigger the terminal to perform beam measurement and reporting. To trigger beam measurement and reporting, it is necessary to schedule the uplink DCI format of PUSCH, that is, the CSI request in DCI format 0_1 / 0_2 to trigger. Therefore, the base station needs to send a DCI again, which brings a large time domain and signaling overhead. In addition, for beam reporting, it currently only includes reporting after the measurement is completed, regardless of the measurement results. Such indiscriminate reporting also results in large reporting signaling overhead.

[0226] FIG2A is an interactive diagram illustrating a beam measurement and reporting method according to an embodiment of the present disclosure. As shown in FIG2A , an embodiment of the present disclosure relates to a beam measurement and reporting method, the method comprising:

[0270] Step S2105: The terminal determines a first uplink channel resource.

[0271] In some implementations, the first uplink channel resource is used to assist the terminal in reporting a measurement value of the first reference signal resource to the network device.

[0272] In some implementations, the network device may send DCI signaling. Optionally, the terminal receives the DCI signaling, where the DCI signaling is used to configure the first uplink channel resource.

[0273] In some implementations, the terminal may determine the first uplink channel resource by configuring a configured grant uplink physical shared channel resource through higher-layer signaling. Optionally, the configured grant uplink physical shared channel resource (Configured-grant-PUSCH) includes the first uplink channel resource, and the higher-layer signaling configuration includes but is not limited to RRC signaling and MAC CE signaling.

[0518] FIG5 is a schematic diagram of a beam measurement and reporting method according to an embodiment of the present disclosure. As shown in FIG5A , an embodiment of the present disclosure relates to a beam measurement and reporting method, which includes:

[0519] Step S5101, receiving first information.

[0520] The terminal receives first information, where the first information is used to indicate a new beam. The terminal determines a reference signal resource and / or a measurement value for measurement based on the first information, and obtains a measurement value corresponding to the reference signal resource.

[0521] In some implementations, the first information includes a MACCE, and at least one beam activated by the MACCE corresponds to a codepoint in a TCI field in the DCI.

[0522] In some implementations, beams can also be referred to as TCIstate, including ULTCIstate, DLTCIstate, jointTCIstate, spatialrelationinformation

[0523] In some implementations, the first information includes a MACCE and a downlink DCI format 1_1 / 1_2 for scheduling a PDSCH, the MACCE activates one or more TCIstates corresponding to each of multiple codepoints in the TCI field in the DCI, and the TCI field in the DCI is used to indicate one codepoint among the multiple codepoints.

[0524] Step S5102: Receive first information, where the first information includes a first indication field.

[0525] The first information also includes a first indication field, that is, different from the TCI field, the first indication field is used to indicate the reference signal resource used for measurement and the corresponding measurement value.

[0526] In some implementations, there is a one-to-one correspondence between the codepoint in the first indication field and the reference signal resource and measurement value used for measurement, and the correspondence is configured by higher-layer signaling (such as at least one of RRC signaling and MACCE).

[0527] In some implementations, the reference signal resources used for measurement may include the following:

[0528] Used for channel measurement (resourceforchannel): NZP CSI-RS.

[0529] Resources for Interference: NZPCSI-RS, ZPCSI-RS.

[0530] For beam measurements: NZPCSI-RS, SSB.

[0531] It also includes the QCL message corresponding to each reference signal resource, whether the reference signal resource is sent periodically, aperiodically or semi-persistently, and the corresponding reference signal resource set ID.

[0532] The measurement values ​​include the following: CRI, CSI-RSresourceindicator, RI, ranking indicator, PMI, precoding matrix indicator, CQI, channel quality indicator, LI, layer indicator, CRI-RSRP (from here on the measurement value used for beam measurement, L1-RSRP or L1-SINR, index refers to the number of SRS ports), SSB-index-RSRP, CRI-SINR, SSB-index-SINR, CRI-RSRP-index, SSB-index-RSRP-index, CRI-SINR-index, SSB-index-SINR-index

[0533] Step S5103: Determine reference signal resources and corresponding measurement values ​​based on the TCI state.

[0534] If the first information does not contain a dedicated first indication field, the reference signal resource and the corresponding measurement value are determined directly based on the TCI state. The mapping relationship between the TCI state, reference signal resource, and corresponding measurement value is configured by higher-layer signaling (including RRC and / or MACCE). The specific reference signal resource and measurement value are the same as above.

[0535] Step S5104: reporting the measurement value.

[0536] Step S5105: Determine the reporting trigger event and parameter values ​​related to the reporting trigger event.

[0537] The reporting trigger event includes at least one of the following: the measured L1-RSRP / L1-SINR of the new beam is one offset higher than the currently used beam, the measured L1-RSRP / L1-SINR of the new beam is higher than the first threshold, and / or the L1-RSRP / L1-SINR of the currently used beam is lower than the second threshold, the measured N strongest beams do not include the beam currently in use, and the parameter value includes the value of the above offset, the threshold value, and the value of N.

[0538] How to determine, including at least one of the following: high-level signaling also configures the correspondence between the first indication field or TCI state and the event and / or corresponding parameter value; determined based on default rules or protocol provisions.

[0539] Based on the above two, for example, the reporting trigger event is a default rule or protocol requirement, while the parameter value is a high-level signaling configuration.

[0540] Reporting mode (mapping relationship configured by higher-level signaling): Oneshot reporting, i.e., reporting only once, after the event is satisfied; or reporting immediately after measurement, regardless of the event; Periodic reporting, i.e., reporting periodically after the event is satisfied; or reporting periodically after measurement, regardless of the event; Semi-persistent reporting, i.e., reporting semi-persistently after the event is satisfied; or reporting semi-persistently after measurement, regardless of the event, and the number of reports configured by higher-level signaling; Aperiodic reporting, i.e., reporting aperiodically after the event is satisfied; or reporting aperiodically after measurement, regardless of the event, and the number of reports configured by higher-level signaling.

[0541] The reporting includes group-based beam report (groupbasedbeamreport) or non-group-based beam report (non-groupbasedbeamreport).

[0542] A groupbasedbeamreport can contain beamreports applicable to downlink and / or uplink. For downlink, this means that the beams corresponding to the two reference signals within or between groups are supported by the terminal for simultaneous reception. For uplink, this means that the beams corresponding to the two reference signals within or between groups are supported by the terminal for simultaneous transmission.

[0543] Furthermore, the reported PUCCH or PUSCH resources may also be scheduled by DCI signaling, or a mapping relationship configured by higher-layer signaling.

[0544] The beam measurement and reporting method involved in the embodiments of the present disclosure may include at least one of steps S5101 to S5105. For example, step S510 may be implemented as an independent embodiment, step S5105 may be implemented as an independent embodiment, and steps S5101+S5105 may be implemented as independent embodiments, but are not limited thereto.
