Abstract
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive an indication of an uplink transmission configuration indication (TCI) state. The UE may determine that the uplink TCI state identifies a pathloss reference signal for an associated uplink transmission. The UE may determine an uplink power control parameter for the uplink transmission based at least in part on the pathloss reference signal. Numerous other aspects are provided.
Claims28
A method of wireless communication performed by a user equipment (UE), comprising:
- receiving an indication of an uplink transmission configuration indication (TCI) state in a downlink control information communication,
- wherein the indication of the uplink TCI state includes an indication of one or more types of uplink quasi-co-location (QCL) relationships;
- identifying that the uplink TCI state includes an indication of a pathloss reference signal for an associated uplink transmission;
- and
- identifying an uplink power control parameter for the associated uplink transmission based at least in part on the pathloss reference signal.
A method of wireless communication performed by a network entity, comprising:
- transmitting an indication of an uplink transmission configuration indication (TCI) state in a downlink control information communication,
- wherein the indication of the uplink TCI state includes an indication of one or more types of uplink quasi-co-location (QCL) relationships;
- and
- transmitting an associated pathloss reference signal based at least in part on the uplink TCI state,
- wherein the uplink TCI state includes an indication of the associated pathloss reference signal.
A user equipment (UE) for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- receive an indication of an uplink transmission configuration indication (TCI) state in a downlink control information communication,
- wherein the indication of the uplink TCI state includes an indication of one or more types of uplink quasi-co-location (QCL) relationships;
- identify that the uplink TCI state includes an indication of a pathloss reference signal for an associated uplink transmission;
- and
- identify an uplink power control parameter for the associated uplink transmission based at least in part on the pathloss reference signal.
A network entity for wireless communication, comprising:
- a memory;
- and
- one or more processors coupled to the memory, the one or more processors configured to:
- transmit an indication of an uplink transmission configuration indication (TCI) state in a downlink control information communication,
- wherein the indication of the uplink TCI state includes an indication of one or more types of uplink quasi-co-location (QCL) relationships;
- and
- transmit an associated pathloss reference signal based at least in part on the uplink TCI state,
- wherein the uplink TCI state includes an indication of the associated pathloss reference signal.
