Claim of US Patent No. 11,115,933


1. A method comprising:determining, by a base station, an uplink data channel power control parameter set for an uplink data channel beam pair;
determining, by the base station, a sounding reference signal beam pair for a sounding reference signal resource;
selecting, by the base station, the uplink data channel power control parameter set to be used by a user device to adjust a sounding reference signal transmission power, the selecting being performed based on the uplink data channel beam pair matching the sounding reference signal beam pair; and
receiving, by the base station from the user device via the sounding reference signal resource and the sounding reference signal beam pair, a sounding reference signal with a sounding reference signal transmission power set based on the uplink data channel power control parameter set.
