Joint resource scheduling for full-duplex cellular system

Abstract

In this paper, the joint resource scheduling strategies in a full-duplex cellular system are studied. In the system, the base station (BS) is enabled full-duplex transmission, while the user equipments (UEs) are still traditional half-duplex. Firstly, we propose a binary-integer programming problem concerning cell throughput and solve it through exhaustive search algorithm. Furthermore, considering the feasibility of the optimal algorithm, two suboptimal heuristic algorithms are raised: one is distance isolation algorithm, the other one is user filtering and dynamic adjustment algorithm. Then, to verify the performance of the proposed algorithms, some system level simulations are conducted in a single cell full-duplex scenario. The results show the comparison of system throughput between traditional half-duplex system and full-duplex system under different self-interference cancellation capabilities at the BS. The throughput performance of the proposed algorithms changing with self-interference cancellation capability and user number is analyzed.
