Patent ID: 10075218

Abstract:
A method for user equipment (UE) in a wireless communication network. The method comprises identifying a plurality of beams for a semi-open-loop PDSCH data transmission based on at least one of a plurality of precoder cycling types, wherein a precoder comprises a beam and a co-phase, and the plurality of precoder cycling types including at least one of a beam cycling from the plurality of beams or a co-phase cycling from a plurality of co-phases, receiving PDSCH data through the semi-open-loop PDSCH data transmission according to the at least one of the plurality of precoder cycling types, and identifying the plurality of beams based on the at least one of the plurality of precoder cycling types, wherein the precoder comprising the beam and co-phase, and the plurality of precoder cycling types is cycled across a plurality of resource blocks (RBs) using the at least one of the beam cycling or the co-phase cycling with at least one of a cycling period or granularity from at least one of a plurality of cycling periods or granularities including at least one of a single resource element (RE), a single RB, multiple REs, or multiple RBs.
