Abstract

An improved multiuser Scheduling Scheme which can reduce feedback load and preserve most of the capacity performance in MIMO Channels is proposed in this paper. Each user compares its Maximum SINR to a threshold and only those who fall above it along with the index transmit antenna are sent back to the base station. The base station allocates independent channels to the users with the highest SINR. The average capacity of the proposed method is obtained and shown to match the simulation.
