In order to enable those skilled in the art to better understand the embodiments of the present application, the following description is made.

One, regarding beam indication (beam indication) mechanism:

after the beam measurement and the beam report, the network may perform beam indication on the downlink and uplink channels or reference signals, so as to establish a beam link between the network and the UE, thereby implementing transmission of the channels or the reference signals.

1. For the beam Indication of a Physical Downlink Control Channel (PDCCH), the network configures K Transmission Configuration Indication states (TCI states) for each Control Resource Set (Control Resource Set core) using Radio Resource Control (RRC) signaling, and when K >1, 1 TCI state is indicated or activated by a Medium Access Control Element (MAC CE), and when K >1, no additional MAC CE command is needed. When monitoring the PDCCH, the UE uses the same Quasi-co-location (QCL) for all Search spaces (Search spaces) in the CORESET, i.e., uses the same TCI state to monitor the PDCCH. The Reference Signal (RS) in the TCI State, for example, a periodic Channel State Information Reference Signal resource (CSI-RS), a semi-persistent CSI-RS resource, a Synchronization Signal (SSB), and the like, and a Physical Downlink Control Channel-specific Demodulation Reference Signal (UE-specific PDCCH DMRS) port of the terminal are spatial QCL. The UE can know which receiving beam is used to receive the PDCCH according to the TCI state.

2. For beam indication of a Physical Downlink Shared Channel (PDSCH), a network configures M TCI states through RRC signaling, activates 2N TCI states using a MAC CE command, and then notifies the TCI states through N TCI fields of Downlink Control Information (DCI), where a Reference Signal in the TCI states and a Demodulation Reference Signal (Demodulation Reference Signal) port of the PDSCH to be scheduled are DMRSs of the QCL. The UE can know which receiving beam is used to receive the PDSCH according to the TCI state.

3. For the beam indication of the Channel State Information Reference Signal (CSI-RS), when the CSI-RS type is periodic CSI-RS, the network configures QCL Information for the CSI-RS resource through RRC signaling. When the CSI-RS type is semi-persistent CSI-RS, the network indicates QCL information thereof when activating one CSI-RS resource from the RRC-configured CSI-RS resource set through a MAC CE command. When the CSI-RS type is the aperiodic CSI-RS, the network configures QCL for the CSI-RS resource through RRC signaling, and uses the DCI to trigger the CSI-RS.

4. For the beam indication of a Physical Uplink Control Channel (PUCCH), the network configures Spatial relationship information for each PUCCH resource through Physical Uplink Control Channel Spatial relationship information (PUCCH-Spatial relationship info) using RRC signaling, and when the Spatial relationship information configured for the PUCCH resource includes a plurality of pieces, indicates or activates one of the pieces of parameter Spatial relationship information using MAC-CE. When the spatial relationship information configured for the PUCCH resource includes only 1, no additional MAC CE command is required.

5. For the beam Indication of the PUSCH (Physical Uplink shared Channel), the spatial relationship information of the PUSCH is that when the DCI carried by the PDCCH schedules the PUSCH, each SRI site (code point) of an Uplink Scheduling Request Indication field (SRI field) in the DCI indicates one SRI, and the SRI is used to indicate the spatial relationship information of the PUSCH.

6. For the beam indication of the channel Sounding Reference Signal (SRS), when the SRS type is periodic SRS, the network configures spatial relationship information for SRS resources through RRC signaling. When the SRS type is semi-persistent SRS, the network activates one from a set of RRC configured spatial relationship information by MAC CE command. When the SRS type is the aperiodic SRS, the network configures spatial relationship information for the SRS resource through RRC signaling, and may also use the MAC CE command to update the spatial relationship information of the aperiodic SRS resource.

Second, regarding beam indication in a multiple-Transmission Reception Point (multi-TRP) scene:

the 3GPP release 16 introduces a multi-TRP scenario, and can be divided into single DCI transmission and multiple DCI transmission according to the transmission mode of control information, the former is to transmit DCI at one TRP to schedule data transmission on multiple TRPs, and the latter is to allow DCI transmitted at multiple TRPs to schedule data transmission on respective TRPs.

When the DCI schedules the PDSCH, when a scheduling interval (scheduling offset or time offset) between the DCI and the PDSCH is less than or equal to a preset threshold, a default beam needs to be used to transmit the PDSCH. The prior art provides for the following:

1. for multi-Transmission of DCI based on multiple Transmission Reception points or antennas (multi-Transmission Reception Point/multi-Transmission Reception Panel), if a control resource set Pool Index (CORESET Pool Index) is configured, when the scheduling interval is less than or equal to a preset threshold, the UE assumes that PDSCH DMRS port is the QCL of the reference information in the QCL information of the PDCCH configured with the lowest control resource set Pool Index (CORESET with lowest Index) of the same control resource set Pool Index value

The CORESET with local Index is the CORESET with local Index in the CORESET that needs to be monitored by the UE and corresponds to the respective CORESET Pool Index value in the latest slot (latest slot). Where a latest slot refers to the presence of at least one slot in the serving cell active wideband Part (BWP) associated with the CORESET Pool Index of the corresponding CORESET Pool Index.

If the UE does not support the characteristic, the rule of 3GPP Release 15 is reused no matter how the CORESET Pool Index is configured, namely the CORESET with the lowest Index is the CORESET with the lowest Index in the CORESET which needs the UE to monitor in the latest slot, and the CORESET Pool Index is irrelevant.

2. For single-Transmission-Reception-Point or antenna (single-single-Transmission-Reception-Point/single-Transmission-Reception-Panel) based DCI single Transmission, when the scheduling interval is less than or equal to a preset threshold and after receiving an activation command of the TCI state of the UE-specific PDSCH, the UE assumes that the PDSCH DMRS port uses the QCL parameter of the preset TCI state. That is, among the activated TCI states for the PDSCH, a TCI state corresponding to the lowest code bit (lowest code point) is selected from among TCI code bits containing 2 different TCI states.

If all TCI code bits correspond to a single TCI state, then the rule of Release 15 is used.

Note that, the beam information may also be referred to as: spatial relationship (spatial relationship) information, spatial domain transmission filter (spatial filter) information, spatial filter (spatial filter) information, transmission configuration indication state (TCI state) information, quasi co-location (QCL) information, QCL parameters, or the like. The downlink beam information may be generally represented by TCI state information or QCL information. The uplink beam information can be generally expressed using spatial relationship information.

The antenna panel mentioned may also be referred to as: antenna group, antenna port group, antenna set, antenna port set, beam subset, antenna array, antenna port array, antenna sub array, antenna port sub array, logical entity, antenna entity, or the like.

The identity of Panel may be: the identifier of the antenna panel, the identifier of the reference signal resource set, the identifier of the TCI state, the identifier of the QCL information, the identifier of the spatial relationship, etc.
