In one aspect, a method is provided which may be performed by a wireless device such as a base station (BS). The method generally includes receiving sounding reference signals (SRS) and at least one of: feedback regarding interference or a whitening matrix from one or more user equipments (UEs), determining beamforming parameters for transmissions to a group of one or more UEs based, at least in part, on the SRS and at least one of: the feedback regarding interference or the whitening matrix, and transmitting channel state information reference signals (CSI-RS) to UEs in the group using the determined beamforming parameters."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Reference signals and link adaptation for massive MIMO","description":"Aspects of the present disclosure relate to wireless communications and, more particularly, to reference signals (RS) and link adaptation for massive multiple-input multiple-output (MIMO).
