Abstract
Systems and methods determine a PUSCH default beam in NR with multiple UE antenna panel operation and multiple TRP operation.
Claims19
An apparatus for a user equipment (UE) configured for multiple beam operation and including multiple antenna panels, each of the multiple antenna panels corresponding to a respective antenna port group, the apparatus comprising:
- a memory interface to send or receive, to or from a memory device, downlink control information (DCI);
- and
- a processor to:
- process reference signals received through the multiple antenna panels from multiple transmission reception points (TRPs) in a wireless network;
- process a physical downlink control channel (PDCCH) to determine the DCI configured to schedule a physical uplink shared channel (PUSCH);
- in response to a DCI format of the DCI being DCI format 0_0:
- determine a default spatial relation of the PUSCH corresponding to a selected physical uplink control channel (PUCCH) resource configured for at least one of a same antenna panel of the multiple antenna panels that receives the PDCCH with the DCI and a same scheduling TRP of the multiple TRPs that transmits the PDCCH with the DCI;
- and
- determine a particular antenna port group of the PUSCH, the selected PUCCH resource corresponding to the particular antenna port group;
- and
- generate the PUSCH to transmit according to the default spatial relation.
A non-transitory computer-readable storage medium, the computer-readable storage medium including instructions that when executed by a processor of a user equipment (UE) configured for single transmission reception point (TRP) and multiple antenna panel operation in a wireless network, cause the processor to:
- process a physical downlink control channel (PDCCH) from a TRP to determine downlink control information (DCI) configured to schedule a physical uplink shared channel (PUSCH);
- in response to a DCI format of the DCI being DCI format 0_0, select a particular antenna panel from a plurality of antenna panels;
- determine a default spatial relation of the PUSCH corresponding to a selected physical uplink control channel (PUCCH) resource corresponding to the particular antenna panel, wherein each of the plurality of antenna panels corresponds to a respective antenna port group, the instructions further to configure the processor to determine a particular antenna port group of the PUSCH, the selected PUCCH resource corresponding to the particular antenna port group;
- and
- generate the PUSCH to transmit according to the default spatial relation.
A method to be performed at a processor of a user equipment (UE) configured for multiple beam operation and including multiple antenna panels, where each of the multiple antenna panels correspond to a respective antenna port group, the method including:
- processing reference signals received through the multiple antenna panels from multiple transmission reception points (TRPs) in a wireless network;
- processing a physical downlink control channel (PDCCH) to determine the DCI configured to schedule a physical uplink shared channel (PUSCH);
- in response to a DCI format of the DCI being DCI format 0_0:
- determining a default spatial relation of the PUSCH corresponding to a selected physical uplink control channel (PUCCH) resource configured for at least one of a same antenna panel of the multiple antenna panels that receives the PDCCH with the DCI and a same scheduling TRP of the multiple TRPs that transmits the PDCCH with the DCI;
- and
- determining a particular antenna port group of the PUSCH, the selected PUCCH resource corresponding to the particular antenna port group;
- and
- generating the PUSCH to transmit according to the default spatial relation.
