Abstract: In future wireless communication, the networks will face the dual challenge to support large traffic volumes by providing reliable service for delay-sensitive traffic. To get this challenge, the relay network is introduced here as a new network design for the fourth generation (4G) LTE-Advanced (LTE-A) network. The resource allocation is investigated including subcarrier and power allocation, under statistical quality of service (QoS) constraints for 4G LTE-A relay networks. Filter Bank Multicarrier with Offset Quadrature Amplitude Modulation (FBMC/OQAM) is recognized as an appropriate modulation scheme for 4G/5G wireless technologies. In this paper, we investigate an enhanced LTE-A model for improving energy efficiency in relay network with an extremely low Adjacent Channel Leakage Ratio (ACLR). Our result suggests that the improvement of energy efficiency with extremely low ACLR, when compared with schemes A, B, C & D. With an extremely low ACLR, FBMC/OQAM scheme is a suitable candidate for cognitive radio (CR) applications.
