Abstract
A base station and a UE may use a unified TCI to indicate a power control parameter for a plurality of UL channels. The base station may receive the UE's capability to support the unified TCI power control parameter, and configure the at least one power control parameter associated with at least one of a first component associated with the TCI state and a plurality of second component associated with the plurality of uplink channels.
Claims26
An apparatus for wireless communication at a user equipment (UE), comprising:
- a memory;
- and
- at least one processor coupled to the memory, the at least one processor and the memory being configured to:
- transmit, to a base station, an indication of a UE capability associated with at least one power control parameter;
- receive, from the base station, an indication of a configuration of at least one of a first component of the at least one power control parameter associated with a first transmission configuration indicator (TCI) state or a plurality of second components of the at least one power control parameter associated with one of a plurality of uplink channels, the first component corresponding to each of the plurality of channels associated with the first TCI state;
- and
- apply, to one of the plurality of uplink channels, an uplink transmission power setting associated with at least one of the first component of the at least one power control parameter or the plurality of second components of the at least one power control parameter;
- wherein the at least one power control parameter corresponds to at least one power control parameter setting.
