POWER CONTROL IN FULL DUPLEX SYSTEMS BASED ON PL-RS FOR SELF-INTERFERENCE MEASUREMENT

Abstract:

This disclosure provides systems, devices, apparatus, and methods, including computer programs encoded on storage media, for power control in FD systems based on a PL-RS for measuring self-interference. In aspects, a base station may configure a PL-RS for one or more beam pairs and schedule a DL transmission including the PL-RS. A UE may measure self-interference corresponding to the one or more beam pairs based on the PL-RS and adjust an UL Tx power for a FD operation based on the self-interference measured for the one or more beam pairs. The UE may subsequently transmit an UL transmission for the FD operation based on the adjustment to the UL Tx power, such that the base station may receive an UL transmission having an UL Tx power that is based on the measured self-interference associated with the PL-RS.
