Abstract

As a result of the introduction of relay technique in the Long Term Evolution Advanced (LTE-A) system, the system performance is improved in network coverage, user (UE) fairness and system throughput. Nevertheless, it is important to support the transmission of multimedia application and meet various quality-of-service (QoS) requirements of different traffics. Thus, a two-hop relay system scheduling several QoS-promising traffics is set and we propose a resource allocation algorithm named SPRC. The superiority of the proposed resource allocation algorithm is examined through system level simulation, compared with the two existing algorithms: TH-MLWDF and TFQoS. The results show that PLR is lower, GBR demand is well satisfied, fairness between R-UEs and D-UEs is guaranteed and system throughput is improved by SPRC.
