1. A method in a network entity, the method comprising:
transmitting a first higher layer configuration message including information of a mapping between a set of sounding reference signal indications and a set of power control parameters to a particular user equipment;
transmitting a second higher layer configuration message including a configured grant uplink transmission configuration, wherein the configured grant uplink transmission configuration does not include a sounding reference signal indication to the particular user equipment;
transmitting an activation message in downlink control information for the configured grant uplink transmission configuration to the particular user equipment; and
receiving a configured grant uplink transmission from the particular user equipment;
wherein in response to receiving uplink grant downlink control information including a sounding reference signal resource indication field, the particular user equipment determines power control parameters for the configured grant uplink transmission based on the sounding reference signal resource indication, wherein the particular user equipment determines the power control parameters for the sounding reference signal resource indication based on the mapping indicated in the first higher layer configuration message; and
wherein in response to being configured with only a single sounding reference signal resource for uplink data channel transmission or if a sounding reference signal indication is not present in the uplink grant downlink control information, the particular user equipment determines the power control parameters for the configured grant uplink transmission based on a direct semi-static configuration.
