In some embodiments, the concept of mTRP, i.e., multi-TRP transmission, is introduced; and two control modes of single downlink control information (single Downlink Control Information, S-DCI) and a plurality of downlink control information (Multiple Downlink Control Information, M-DCI) are introduced. Currently only two TRP transmission modes are supported. For multiple TRPs, a terminal may configure multiple antenna panels to enable simultaneous transmission in multiple directions. The MIMO layer number of the maximum physical downlink shared channel (Physical Downlink Shared Channel, PDSCH) supported by the terminal is given by the following information element (Information Element, IE). Since the IE itself is per feature set implemented per carrier (feature set per carrier, FSPC); in the course of mTRP transmission, for intra-band (intra-band) mTRP, the terminal actually transmits between different TRPs on the same carrier; therefore, the number of the transmitted layers can be larger than the actual number of MIMO layers reported by the maximum downlink MIMO layer (maxNumberMIMO-LayerstPDSCH). This is also the sense of introducing mTRP, enabling an increase in throughput.

In some embodiments, the maximum downlink MIMO layer number (maxnumbermmo-LayersPDSCH) may be as follows: the maximum number of spatial multiplexing layers supported by the UE for Downlink (DL) reception. For single component carrier (Component Carrier, CC) independent NR, mandatory capability signaling supports at least 4 MIMO layers in the frequency band; where 4 receive antennas (Rx) are designated as mandatory for a given UE and at least 2 MIMO layers are supported in FR 2. If not, the UE does not support MIMO on the component carrier.

Therefore, a new reporting mechanism is required to be introduced into the terminal, and the maximum PDSCH MIMO layer number supported under the condition that each antenna panel corresponds to each TRP in the mTRP scene is reported, so that the network can configure the corresponding MIMO layer number of the terminal in the mTRP scene according to the correct reporting value, and the throughput rate of the terminal is improved.

In some embodiments, in case of CSI Resource configuration (CSI-ReportConfig) configured with beam report R17 (groupBasedBeamReporting-R17) of the group, the terminal may measure configured resources of CSI-RSs or SSBs that may be measured by the terminal simultaneously in different sets of CSI resources (CSI Resource sets) for two TRPs, and may report on one CSI report (CSI report). Optionally, the terminal may support at most 4 sets of CSI-RS or SSB measurements according to the configuration; the measurement value of the L1-RSRP reported by each group is a measurement value obtained after the terminal receives measurement reference information of different TRPs simultaneously based on different panels. Alternatively, the terminal may be the UE in the above embodiment.

In some embodiments, in case CSI-ReportConfig configures groupBasedBeamReporting-r17, the reporting of its RSRP includes the channel measurement resource set identity (Channel Measurement Resource set Identifier, CMR set ID) of the strongest L1-RSRP. Alternatively, the terminal may support reporting of 4 sets of group channel measurement resources, as well as measurements of L1-RSRP in each group based on corresponding SSBs and/or CSI-RSs. Alternatively, the measurement value in the first set #0 is the absolute value of 7 bits (bits), while the remaining 7 measurement values are the relative values of 4 bits. Alternatively, set #0 and set #1 correspond to measured values in a first TRP (e.g., TRP 0) and a second TRP (e.g., TRP 1), respectively. Alternatively, the terminal may be the UE in the above embodiment.

Therefore, the terminal can introduce the supportable maximum MIMO layer number for each TRP by each antenna panel in the L1-RSRP measurement report; the base station can correspondingly perform multi-layer MIMO transmission scheduling.

The embodiment of the disclosure provides a scheduling method, which is executed by network equipment and comprises the following steps: and determining a beam group corresponding to the maximum value of the sum of the first layer number and the second layer number in the plurality of group information as a beam group for transmission. Optionally, the network device determines a beam in a beam group corresponding to a maximum sum of the first layer number and the second layer number in the plurality of group information as a beam for transmission.

For example, referring to table 2, if the first layer number of beam group 1, i.e., the maximum MIMO layer number "maxmmimo layer1" supported by beam group 1 for the first TRP is 2 layers, and the second layer number of beam group, i.e., the maximum MIMO layer number "maxmmimo layer2" supported by beam group 1 for the second TRP is 4 layers; the first layer number of beam set 2, i.e., the maximum MIMO layer number "MaxMIMOlayer3" supported by beam set 2 for the first TRP is 4 layers, and the second layer number of beam set 2, i.e., the maximum MIMO layer number "MaxMIMOlayer4" supported by beam set 2 for the second TRP is 4 layers; the first layer number of beam set 3, i.e., the maximum MIMO layer number "MaxMIMOlayer5" supported by beam set 3 for the first TRP is 1 layer, and the second layer number of beam set 3, i.e., the maximum MIMO layer number "MaxMIMOlayer6" supported by beam set 3 for the second TRP is 4 layer; the first layer number of beam set 4, i.e., the maximum MIMO layer number "MaxMIMOlayer7" supported by beam set 4 for the first TRP is 4 layers, and the second layer number of beam set 4, i.e., the maximum MIMO layer number "MaxMIMOlayer8" supported by beam set 4 for the second TRP is 2 layers; the sum of the first layer number and the second layer number in the beam group 2 is 4+4=8 layers, which is the maximum value in the 4 beam groups; the network device determines the beam set for transmission as beam set 2. Optionally, the network device determines that a beam corresponding to SSB and/or CSI-RS indicated by SSBRI and/or CRI in beam group 2 is a beam for transmission.

In this way, in the embodiment of the present disclosure, the network device may select a beam group corresponding to the sum of the first layer number and the second layer number as the beam group for transmission, or select a beam corresponding to the maximum value for transmission, so that the throughput rate of the UE may be greatly improved.

The embodiment of the disclosure provides a scheduling method, which is executed by network equipment and comprises the following steps: and determining a beam group corresponding to the sum of the first layer number and the second layer number in the plurality of group information being greater than a preset value as the beam group for transmission. Optionally, the network device determines a beam in a beam group corresponding to a sum of the first layer number and the second layer number in the plurality of group information being greater than a predetermined value as the beam for transmission.

Optionally, the predetermined value is greater than or equal to the first value. For example, the predetermined value is 6 or 7 or 8, etc.

Illustratively, based on the above example, if the predetermined value is 8, the network device determines that the beam group for transmission is beam group 2, or determines that the beam for transmission is a beam in beam group 2. Or if the predetermined value is 6, the network device determines that any one of the beam group 1, the beam group 2 and the beam group 4 is the beam group used for transmission, or determines that the beam in any one of the beam group 1, the beam group 2 and the beam group 4 is the beam used for transmission.

Thus, in the embodiment of the present disclosure, the network device may select a beam group corresponding to the first layer number and the second layer number that are greater than the predetermined group, that is, a beam group with a relatively greater sum of the first layer number and the second layer number, or select a beam in the relatively greater beam group for transmission, so that the throughput of the UE may also be improved to a certain extent.

The embodiment of the disclosure provides a scheduling method, which is executed by network equipment and comprises the following steps: and determining a beam group corresponding to the maximum value of the L1-RSRP in the at least two group information as a beam group for transmission based on the fact that the sum of the first layer number and the second layer number of the at least two group information is the same. Optionally, the network device determines a beam in a beam group corresponding to the maximum value of L1-RSRP in the at least two group information as a beam for transmission. Alternatively, the L1-RSRP is a sum of L1-RSRPs for each TRP; for example, the L1-RSRP for beam set 1 is: beam 1 is the sum of the L1-RSRP1 corresponding to the first TRP and the L2-RSRP corresponding to the second TRP.

For example, referring to table 2, if the first layer number of beam group 1, i.e., the maximum MIMO layer number "maxmmimo layer1" supported by beam group 1 for the first TRP is 4 layers, and the second layer number of beam group, i.e., the maximum MIMO layer number "maxmmimo layer2" supported by beam group 1 for the second TRP is 4 layers; the first layer number of beam set 2, i.e., the maximum MIMO layer number "MaxMIMOlayer3" supported by beam set 2 for the first TRP is 4 layers, and the second layer number of beam set 2, i.e., the maximum MIMO layer number "MaxMIMOlayer4" supported by beam set 2 for the second TRP is 4 layers; the first layer number of beam set 3, i.e., the maximum MIMO layer number "MaxMIMOlayer5" supported by beam set 3 for the first TRP is 1 layer, and the second layer number of beam set 3, i.e., the maximum MIMO layer number "MaxMIMOlayer6" supported by beam set 3 for the second TRP is 4 layer; the first layer number of beam set 4, i.e., the maximum MIMO layer number "MaxMIMOlayer7" supported by beam set 4 for the first TRP is 4 layers, and the second layer number of beam set 4, i.e., the maximum MIMO layer number "MaxMIMOlayer8" supported by beam set 4 for the second TRP is 2 layers; the sum of the first and second layers in beam set 1 and beam set 2 is 4+4=8 layers. If the sum of the L1-RSRP1 corresponding to the first TRP and the L2-RSRP2 corresponding to the second TRP in beam set 1 is greater than the sum of the L1-RSRP3 corresponding to the first TRP and the L2-RSRP4 corresponding to the second TRP in beam set 2, the network device determines that beam set 1 is the beam set for transmission. Optionally, the network device determines that a beam corresponding to SSB and/or CSI-RS indicated by SSBRI and/or CRI in beam group 1 is a beam for transmission.

Thus, in the embodiment of the present disclosure, the sum of the first layer number and the second layer number of the plurality of beam groups is the same and is the maximum value, and it may be determined that the beam group corresponding to the maximum value of the L1-RSRP in the plurality of beam groups is the beam group used for transmission, or the beam in the beam group is the beam used for transmission, so that the UE achieves the relatively optimal throughput rate.

The embodiment of the disclosure provides a scheduling method, which is executed by network equipment and comprises the following steps: and determining a beam group corresponding to any one of the at least two group information as a beam group for transmission based on the fact that the sum of the first layer number and the second layer number of the at least two group information is the same. Optionally, the network device determines a beam in a beam group corresponding to any one of the at least two group information as a beam for transmission.

For example, based on the above example, if the sum of the first layer number and the second layer number in the beam group 1 and the beam group 2 is 8 layers and is the maximum value of the sum of the first layer number and the second layer number in the 4 beam groups, the network device may determine that the beam group 1 or the beam group 2 is the beam group for transmission. Optionally, the network device determines that the beam corresponding to SSB and/or CSI-RS indicated by SSBRI and/or CRI in beam group 1 or beam group 2 is the beam used for transmission.

In this way, in the embodiment of the present disclosure, the sum of the first layer number and the second layer number of the plurality of beam groups is the same and is the maximum, and then any one of the plurality of beam groups is selected as the beam group for transmission, or the beam of any one of the plurality of beam groups is selected as the beam for transmission, so that the throughput of the UE can also be greatly improved.

Referring to table 2, "MaxMIMOlayer1" through "MaxMIMOlayer8" are reported.
