The most challenging issues that must be addressed when developing next generation wireless network standards throughput and quality-of-service (QoS).The current standards include MIMO (multiple-input/multiple-output) and the multi-hop relay technologies are the viable options for improving the channel capacity. This paper, describes a Fixed relay station cooperated beam-forming technique which combines the MIMO and multi-hop relay to guarantee the QOS of edge users. We assume that the Fixed Relay Station (FRS) is in line-of-sight (LOS) with the base station (BS). First, we define a criterion needed to install the FRS. Second, we construct a weight matrix having a lower complexity. Finally we propose a user selection algorithm in sync with MIMO and multihop relay technologies. The simulation results show that the proposed method can improve both the QOS of edge users and the sum-rate. © EuroJournals Publishing, Inc. 2012.
