Claim of US Patent No. 10,993,189

1. A method in a user equipment, the method comprising:determining configuration information for a transmission based on a configured uplink grant;
receiving information of an assigned one of a plurality of different received by a network entity power levels for each user equipment for a given transmission instance;
determining a transmit power offset based on the received information of the assigned one of the plurality of different received by the network entity power levels;
determining a transmit power for transmission based on the configuration information of the configured uplink grant by applying the determined transmit power offset, when the determined transmit power with the determined transmit power offset applied is not less than a predefined threshold value, and by not applying the determined transmit power offset, when the determined transmit power with the determined transmit power offset applied is less than the predefined threshold value; and
performing an uplink transmission using the determined transmit power for transmission.
