摘要:
Aspects of the present disclosure relate to deriving spatial receive parameters for quasi-colocation at a user equipment (UE). An exemplary method generally includes receiving a plurality of beams from a base station in a plurality of coarse directions, determining, based on the plurality of beams, a first spatial colocation parameter, transmitting an indication of a coarse direction associated with a beam having a highest receive strength of the plurality of beams, receiving a plurality of second beams from the base station based on the indication, the plurality of second beams having a narrower beam width than the plurality of beams and covering a beam width of the beam associated with the indicated coarse direction, determining, based on the plurality of second beams, a second spatial colocation parameter, transmitting an indication of the second beam having a highest receive strength, and refining at least one of the first or second spatial colocation parameters.
