Abstract
A method of wireless communication by a UE (user equipment) includes setting a timing parameter based on an uplink TCI (transmission configuration indication) state. The method also includes adjusting uplink transmit timing for an uplink transmission based on the timing parameter.
Claims28
A method of wireless communication by a UE (user equipment), comprising:
- setting a timing advance parameter for a timing advance group (TAG) of the UE based on a quasi-collocated (QCL) source reference signal (RS) indicated by an uplink TCI (transmission configuration indication) state, the QCL source RS from a configured resource set;
- and
- adjusting uplink transmit timing for an uplink transmission based on the timing advance parameter for the TAG of the UE, the timing advance parameter being based on the QCL source RS indicated by the uplink TCI state.
An apparatus of a UE (user equipment) for wireless communication, comprising:
- memory, and
- at least one processor operatively coupled to the memory, the memory and the at least one processor configured:
- to set a timing advance parameter for a timing advance group (TAG) of the UE based on a quasi-collocated (QCL) source reference signal (RS) indicated by an uplink TCI (transmission configuration indication) state, the QCL source RS from a configured resource set;
- and
- to adjust uplink transmit timing for an uplink transmission based on the timing advance parameter for the TAG of the UE, the timing advance parameter being based on the QCL source RS indicated by the uplink TCI state.
