METHOD AND APPARATUS FOR NON-COHERENT PUCCH TRANSMISSION

Abstract:

The apparatus of wireless communication is a UE and a base station. The UE received a control information indicating a reference signal (RS) mode for a non-coherent transmission of an UCI to the base station. The UE in the RS mode may map an RS according to an RS pattern and the UCI into resource elements assigned for a PUCCH to transmit the UCI and transmit an uplink control signal including the RS and the UCI to the base station over the PUCCH. The UE may determine a RS pattern and puncture the resource elements mapped with the code point of the UCI that corresponds to the RS pattern and map the RS based on the RS pattern. The UE may map the RS based on the RS pattern and map the code point by rate matching around the resource into which the RS is mapped.
