Abstract:
A system includes remote unit(s) (RU(s)). The RU(s) is/are configured to transmit at least one signal on a plurality of different beam patterns, each beam pattern comprising an active subset an inactive subset of a plurality of fine beams covering an area of a cell. The RU(s) is/are also configured to receive, from each of a plurality of user equipment (UEs) in the area, a respective signal strength measurement for each of the plurality of different beam patterns. The system also includes a centralized unit communicatively coupled to the plurality of RUs via a fronthaul interface. The centralized unit is configured to determine a bit vector for each UE based on a combination of the signal strength measurements from the respective UE. The centralized unit is configured also to select a respective fine beam for each UE based on the respective bit vector for the UE.
