Systems and methods for enabling power control of multiple Transmission Reception Points (TRPs) are provided. In some embodiments, the wireless device performs at least one of: receiving in a Downlink Control Information (DCI) a first Transmit Power Control (TPC) command and a second TPC command and an indication of a first transmission of the physical channel to a first TRP associated with a first closed-loop and a second transmission of the physical channel to a second TRP associated with a second closed-loop; determining a first and a second transmit power based on the first and the second TPC commands, respectively; and applying the first and the second transmit power to the first UL transmission and the second UL transmission, respectively. In this way, some embodiments herein enable more accurate per TRP power control with a simple signaling for multiple UL transmissions towards different TRPs scheduled by a single DCI.
A method performed by a wireless device for enabling per Transmission Reception Point, TRP, Uplink, UL, power control for a UL physical channel to be transmitted to multiple TRPs, the method comprising:
