Dynamic resource allocation in relay-aided celluar OFDMA systems [celluar read cellular]

In this paper, we consider the problem of joint bandwidth and power allocation for the relay aided orthogonal frequency division multiple access (OFDMA) system. A fractional frequency reuse (FFR) technique for interference mitigation in relay OFDMA cellular wireless networks is proposed based on a s...
