DATA-AWARE PRECODING FOR BASE STATIONS AND USER EQUIPMENT (UEs)

WIPO Patent Application WO/2022/236456

A1

A method for wireless communication performed at a user equipment (UE) includes receiving, from a base station, an indication that the base station supports data-aware precoding. The method also includes transmitting, to the base station based on the base station supporting data-aware precoding, an indication that the UE supports the data-aware precoding and an indication of data-aware precoding capabilities of the UE. The method also includes receiving, from the base station, a current precoding mode indicator identifying a current precoding mode for precoding one or more resource elements of one or more subcarriers at the base station. The method further includes receiving, from the base station, a data transmission on a data channel, both the data transmission and the data channel precoded based on the current precoding mode. The method still further includes decoding the data transmission and the data channel based on the current precoding mode.
