Abstract

In this paper, we consider efficient power control scheme for a multiuser cooperative multiplexing system with fixed relays employing decode-and-forward relaying schemes. We take two power control problems into account and propose efficient schemes for each problem: transmission power control for the fixed relay and power allocation problem between a base station and the fixed relay. Proposed schemes utilize only reported channel state information required to perform multiuser scheduling. Simulation results show that the power control scheme for the fixed relay significantly reduces unnecessary power consumption and the power allocation scheme for the base station and the fixed relay enhances the system performance by optimizing transmit power to maximize sum capacity.
