QCL (quasi co-location) indication for beamforming management

Abstract:

Techniques for employing QCL (Quasi Co-Location) signaling for beamforming management are discussed. One example embodiment can comprise an apparatus that can determine whether a first set of RS (Reference Signal) APs (Antenna Ports) are QCL-ed (Quasi Co-Located) with a second set of RS APs with respect to one or more large-scale channel properties, wherein the properties comprise an average angle-of-arrival and an angle of arrival spread, and wherein the first set of RS APs are distinct from the second set of RS APs; and select, based on the determination, beamforming weights for reception via the second set of RS APs. In the same or other embodiments, QCL can be indicated between RS antenna port(s) and antenna port(s) of beam reference signal is used to assist UE beamforming for reception of data or control channel transmitted on DM-RS antenna ports.
