In this paper, different models of LTE-based cooperative communications are proposed and investigated, where replaying schemes may be applied in LTE-based system for improving the spatial diversity gain. More specifically, cooperative transmission in our proposed system is formed by employing the Mobile Station (MS), Relay Station (RS) and Base Station (BS) in LTE environment. The system can be operated in both Amplify-and-Forward (AF) regime and Decode-and-Forward (DF) regime, in order to take advantages of cooperative communications in various scenarios of relay positions. | Cooperative communication in lte systems invoking amplify and forward and decode and forward
