Abstract:
Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may determine, based at least in part on a set of channel state information reference signals (CSI-RSs), a plurality of hypotheses associated with a plurality of transmission/reception points (TRPs), wherein the UE is configured to receive non-coherent transmissions across the plurality of TRPs according to at least one of a transparent transmit diversity scheme, a non-transparent transmit diversity scheme, or a closed-loop block diagonal precoder scheme, and wherein a coherent precoder is configured within each of the plurality of TRPs. In some aspects, the UE may determine, based at least in part on the plurality of hypotheses, channel state information (CSI) feedback associated with the plurality of TRPs. Numerous other aspects are provided.
