SWITCH BETWEEN COHERENT AND NON-COHERENT PUCCH TRANSMISSIONS

Abstract:

Aspects of the present disclosure provide apparatus, methods, processing systems, and computer readable mediums that allow a switch between coherent physical uplink control channel (PUCCH) transmissions (e.g., that include demodulated reference signals (DMRS)) and non-coherent PUCCH transmissions (e.g., without DMRS). An example method by a user equipment (UE) generally includes receiving, from a network entity, a configuration of a set of PUCCH resources with different PUCCH formats, receiving signaling, from the network entity, indicating one of the PUCCH resources for a PUCCH transmission and whether the PUCCH transmission is to be sent as a coherent transmission or non-coherent transmission, and sending the coherent or non-coherent PUCCH transmission in accordance with the indication.
