Title: UE SELECTION AND TRANSMISSION RANK ESTIMATION FOR MU-MIMO COMMUNICATION SYSTEMS
Abstract:
A method of scheduling transmission in a MIMO system is provided that includes joint UE and rank selection. The method comprises selecting, at a base station, a UE of a plurality of candidate UEs and a MIMO rank for the selected UE according to an inter-UE interference between the selected UE at the MIMO rank and one or more scheduled UEs. The selected UE is then scheduled for transmission, at the MIMO rank, with the scheduled UEs.
