Relaying is a promising technology in time-division duplexing long-term evolution-advanced networks to improve cell-edge performance. Owing to the great degree of difference between the transmitting power of evolved node B and relay nodes, uplink performance and downlink performance sometimes cannot be optimised simultaneously. As an important aspect of radio resource management, the conventional route-selection strategies optimise either downlink performance only or uplink performance only. However, the users launching different types of services have different requirements in uplink and downlink. By taking service type into consideration, an adaptive bidirectional optimisation (ABO) route-selection strategy is proposed to adaptively and dynamically optimise uplink and downlink performance. The objective of the proposed ABO strategy is to maximise the user bidirectional throughput which is the sum throughput of uplink and downlink. Moreover, load balancing is considered in the formulation of the proposed strategy. Through system-level simulation, it can be seen that the proposed strategy is better than the benchmark strategies in different frame configurations.

“…In [5], a centralized power allocation algorithm was proposed to minimize the weighted sum power of FR and MT for a traditional relay-assisted cellular network. In [6], the uplink performance of a relay-assisted cellular network was studied, where a genetic algorithm was used to optimize FRs' position to minimize MTs' transmission power. In [7], a distributed power control algorithm applied to cooperative FRs was proposed to decrease the average power consumption per MT in cellular network.…”

This paper jointly investigates the bandwidth allocation, transmission strategy and relay positions for two-way transmission aware cellular networks with network coding (NC). Our goal is to minimize the transmission power of mobile terminals (MTs). Consider a cellular system, where multiple MTs exchange information with their common base station, firstly, we propose an efficient bandwidth allocation method and then give a transmission strategy for each MT to determine whether to use relay stations (RSs) for its two-way transmission with the BS or not. To further improve the system performance, the optimal positions of RSs are also jointly discussed. A GA-based algorithm is presented to obtain the optimum positions for RSs. Besides, the impacts of frequency reuse on MT's transmission power and system spectral efficiency (SE) under different number of relays are also discussed in our work. Numerical results show that the proposed NC aware scheme can extend MTs' battery life at least 6% more than traditional method.
