Abstract
The disclosed method and an apparatus are directed to determine an uplink transmission power in New Radio (NR) systems by a wireless transmit/receive unit (WTRU) for transmitting at least one physical uplink shared channel (PUSCH), using multiple beams toward multiple Tx/Rx points (TRPs). The method includes determining common parameters that are common to the multiple beams. The method also includes determining beam-specific parameters like a configurable fractional power compensation factor for each beam, and a configurable maximum transmit power level for each beam, which are determined dynamically or semi-statically based on deployment, WTRU mobility, or interference level. The method further includes transmitting at least one codeword using at least one of the multiple beams, each of the multiple beams having a transmission power calculated based on the common parameters and the beam-specific parameters.
