Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication to apply, for one or more uplink communications of a spatial division multiplexing (SDM) configuration, a group indication associated with downlink beams. The UE may transmit the one or more uplink communications based at least in part on the group indication associated with the downlink beams. Numerous other aspects are described.
Claims30
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving an indication of configurations of a set of transmission control indication (TCI) state groups;
- receiving an indication to apply, for one or more uplink communications of a spatial division multiplexing (SDM) configuration, a TCI state group of the set of TCI state groups, wherein the TCI state group is associated with downlink beams;
- and
- transmitting the one or more uplink communications based at least in part on the TCI state group being associated with the downlink beams;
- wherein the method further comprises at least one of:
- transmitting a request to stop transmitting uplink communications based at least in part on the TCI state group associated with the downlink beams;
- or
- receiving an indication to stop transmitting uplink communications based at least in part on the TCI state group being associated with the downlink beams.
5 more elements
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors, coupled to the memory, configured to:
- receive an indication of configurations of a set of transmission control indication (TCI) state groups;
- receive an indication to apply, for one or more uplink communications of a spatial division multiplexing (SDM) configuration, a TCI state group of the set of TCI state groups, wherein the TCI state group is associated with downlink beams;
- and
- transmit the one or more uplink communications based at least in part on the TCI state group being associated with the downlink beams;
- wherein the one or more processors are further configured to perform at least one of the following:
- transmit a request to stop transmitting uplink communications based at least in part on the TCI state group associated with the downlink beams;
- or
- receive an indication to stop transmitting uplink communications based at least in part on the TCI state group being associated with the downlink beams.
8 more elements
A non-transitory computer-readable medium storing a set of instructions for wireless communication, the set of instructions comprising:
- one or more instructions that, when executed by one or more processors of a user equipment (UE), cause the UE to:
- receive an indication of configurations of a set of transmission control indication (TCI) state groups;
- receive an indication to apply, for one or more uplink communications of a spatial division multiplexing (SDM) configuration, a TCI state group of the set of TCI state groups, wherein the TCI state group is associated with downlink beams;
- and
- transmit the one or more uplink communications based at least in part on the TCI state group being associated with the downlink beams;
- wherein the one or more instructions that, when executed by the one or more processors, further cause the UE to perform at least one of:
- transmit a request to stop transmitting uplink communications based at least in part on the TCI state group associated with the downlink beams;
- or
- receive an indication to stop transmitting uplink communications based at least in part on the TCI state group being associated with the downlink beams.
6 more elements
An apparatus for wireless communication, comprising:
- means for receiving an indication of configurations of a set of transmission control indication (TCI) state groups;
- means for receiving an indication to apply, for one or more uplink communications of a spatial division multiplexing (SDM) configuration, a TCI state group of the set of TCI state groups, wherein the TCI state group is associated with downlink beams;
- and
- means for transmitting the one or more uplink communications based at least in part on the TCI state group associated with the downlink beams;
- wherein the apparatus further comprises at least one of:
- means for transmitting a request to stop transmitting uplink communications based at least in part on the TCI state group associated with the downlink beams;
- or
- means for receiving an indication to stop transmitting uplink communications based at least in part on the TCI state group being associated with the downlink beams.
