Abstract

Abstract: Reducing energy consumption and extending battery life for mobile terminals (MTs) are becoming increasingly important to mobile communications. This paper proposes a bandwidth allocation method to minimize MTs’ average transmission power with the help of network coding (NC) in relay-aided cellular
networks for two-way transmission. We first provide bandwidth allocation methods for direct transmission and relay-aided transmission respectively. An MT path selection strategy is then proposed. An optimization algorithm is presented to jointly optimize RS locations, bandwidth resources allocation, and MT path selection. Numerical results show that relays operating in the NC mode can extend MT battery life by at least 8.59% with respect to those operating in the decode-and-forward (DF) mode.

Key words: relay-aided cellular network, energy efficiency, two-way transmission, network coding
