摘要

异构网络中,宏基站在时域选取几乎空白子帧(ABS),降低功率传输,可有效减小Pico基站扩展范围(CRE)内用户受到的干扰.但鲜有文献联合考虑功率降低和用户的服务质量(QoS)约束.本文提出一种满足用户QoS约束条件下联合网络资源分配和宏基站ABS期间功率控制的算法(RA-APC),算法在资源分配和ABS功率控制之间来回迭代求解.仿真结果表明,该算法收敛速度快,能够实现网络资源合理利用,有效提升系统整体性能.

Abstract

In heterogeneous networks, Macro eNodeBs reduce transmit power on almost blank subframe (ABS) so that Pico cell range expansion(CRE) users could be protected from cross-layer interference. However, few focus on power reduction and user QoS constraints. In this paper, a joint resource allocation and ABS power control algorithm(RA-APC) is proposed. The algorithm is carried out by iterating between RA and APC under user QoS constraints. Simulation results show that the proposed algorithm converges fast and improves overall network utility.
