Abstract
In one embodiment, a method includes receiving SRS received from a plurality of UEs associated with the base station from an RU associated with the base station, estimating strengths or signal-to-noise ratios (SNRs) for pre-determined beams for each of the plurality of UEs based on the received SRS, selecting a subset of the plurality of UEs to which downlink data is to be transmitted for a RBG in a TTI based on the estimated strengths or SNRs of the pre-determined beams for the plurality of UEs, computing a precoding matrix for the RBG based on the selected subset, preparing multi-layered UE data for the RBG based on the selected subset and the computed precoding matrix, sending the multi-layered UE data and the precoding matrix for the RBG to the RU, where the RU transmits pre-coded multi-layered UE data to the UEs in the subset using MIMO technologies.
