Abstract
Methods, systems, and devices for wireless communications are described. In some systems, a user equipment (UE) may transmit, to a base station, a UE capability message indicating support for at least a first demodulation mode or a second demodulation mode. The first demodulation mode may correspond to a single demodulation procedure associated with a set of antenna ports at the UE, and the second demodulation mode may correspond to multiple demodulation procedures, each procedure associated with a respective subset of antenna ports at the UE. In some cases, the UE may flexibly switch between demodulation modes. The UE may receive, from the base station, one or more downlink signals via one or more downlink beams based on the indication of the first demodulation mode or the second demodulation mode. The UE may demodulate the one or more downlink signals based on the indicated (e.g., an active) demodulation mode.
