Resource Allocation in Full-Duplex OFDMA Wireless Networks with Interactive Service

Along with the diversified development of wireless communication service, the demand for the interactive service with symmetrical quality requirements in uplink and downlink has been increased with a high speed. Recent studies have demonstrated the feasibility of full-duplex communication. Due to transmit and receive data in the same frequency band simultaneously, full-duplex technology is very suitable for interactive service. In this paper, we proposed a joint uplink/downlink resource allocation algorithm in full-duplex OFDMA wireless networks with interactive service, and uplink/downlink resources are allocated jointly to improve the system performance. The resource allocation is formulated as a mixed integer optimization problem to maximize system throughput and it is solved by dual decomposition method. Simulation results show that the proposed algorithm allocates the resources more efficiently in wireless OFDMA networks.
