基于波束成形和干扰对齐的D2D通信蜂窝网络接入控制
Admission control based on beamforming and interference alignment for D2D communication underlaying cellular networks
摘要
Abstract
An admission control algorithm based on beamforming and interference alignment for device-to-device (D2D) communication underlaying cellular networks is proposed. First, some portion of D2D pairs that are the farthest away from the base station (BS) is selected to perform joint zero-forcing beamforming together with the cellular user equipments (UEs) and is admitted to the cellular network. The interference of the BS transmitting signal to the cellular UEs and the portion of D2D pair is eliminated completely at the same time. Secondly, based on the idea of interference alignment, the definition of channel parallelism is given. The channel parallelism of the remaining D2D pairs which are not involved in joint zero-forcing beamforming is computed by using the channel state information from the BS to the D2D devices. The higher the channel parallelism, the less interference the D2D pair suffers from the BS. Finally, in a descending order of channel parallelism, the remaining D2D pairs are reviewed in succession to determine admission to the cellular network. The algorithm stops when the admission of a D2D pair decreases the system sum rate. Simulation results show that the proposed algorithm can effectively reduce the interference of the BS transmitting signal for D2D pairs and significantly improve system capacity. Furthermore, D2D communication is more applicable to short-range links.关键词
