A study on the Uplink scheduling of a Cellular Systems using Received Correlation Information

Abstract

In this paper, we consider multi-user scheduling to maximize the ergodic capacity near the cell boundary in the uplink of cellular systems. The base station (BS) determines a user pair that can minimize the interference from other cells by exploiting the receive correlation matrices of users from adjacent BSs. The performance of the proposed scheme is verified by computer simulation. Simulation results show that the proposed multi-cell scheduling significantly increase the ergodic capacity near the cell boundary compared to conventional random user scheduling, particularly in highly correlated channel environments.
