In this paper, a framework for power allocation of downlink transmissions in orthogonal frequency division multiple access-based decode-and-forward cellular relay networks is investigated. We consider a system with a single base station communicating with multiple users assisted by multiple relays. The relays have limited power which must be divided among(More)
In this paper, a framework for power allocation is presented for downlink transmissions in an OFDMA-based cellular relay network. We consider a system with a single base station communicating with multiple users assisted by multiple relays. The relays have limited power which must be divided among the users they support in order to maximize the data rate of(More)
In this paper, a game theoretic power allocation and relay load balancing scheme for downlink transmission in an OFDMA-based cellular relay network is proposed. In the cell, a BS is located at cell center communicating with multiple users assisted by multiple relays. The relays adopt the decode-and-forward protocol and can cooperatively assist the(More)
