Abstract

In this paper, we propose a user scheduling algorithm based on the codebook for multiuser MIMO system. Users can feedback the CDI information based on the codebook in the multiuser MIMO system. Based on the CDI information, the base station can effectively schedule the users semi-orthogonally. Simulation results show that substantial system throughput gains are achievable by the proposed joint optimal algorithm with appropriate correlation threshold factor.

Keywords: multiuser MIMO CDI user scheduling
