DEMODULATION REFERENCE SIGNAL BUNDLING FOR PHYSICAL UPLINK CONTROL CHANNEL REPETITIONS

Abstract:

Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a base station, an indication that demodulation reference signal (DMRS) bundling is to be used for channel estimation by the base station for one or more physical uplink control channel (PUCCH) repetitions, where the indication is a semi-static configuration or a dynamic indication. The UE may transmit, to the base station, the one or more PUCCH repetitions by maintaining a phase continuity among DMRSs of the one or more PUCCH repetitions based at least in part on receiving the indication that DMRS bundling is to be used. Numerous other aspects are described.
