An efficient genetic-based downlink resource allocation scheme in LTE base stations

摘要

Long term evolution (LTE) base stations (BS) are greatly capable of improving various wireless services. As the amazingly rapid explosion of demands of various network-service applications, how to apropos design an efficient and effective resource allocation scheme for satisfying users' requirements in all perspectives in LTE BSs plays a crucial role. In this study, a state-of-the-art genetic-based resource allocation scheme has now been proposed in LTE BSs for downlink transmissions. The presented scheme supports multi-priority users and employs an aptly modified proportional fair based utility function as the performance metric. The performance evaluation of the proposed scheme is shown able to nearly achieve the optimal solution in an acceptable short time interval of few genetic generations in practice.
