在密集小蜂窝网络场景下,针对同层干扰和跨层干扰问题,提出了一种联合增强型小区间干扰协调和协作多点联合传输的密集小蜂窝干扰管理机制.这种机制考虑了协作多点联合传输对用户的链接、几乎空白子帧的配置、资源块分配的影响,在保证用户最低速率的前提下,最大化系统的吞吐量.仿真结果表明,相比基于增强型小区间干扰协调的干扰管理方法,联合增强型小区间干扰协调和协作多点联合传输的干扰管理方法进一步提升了网络吞吐量,提高了频谱利用率.
Aiming at the problems of co-layer interference and cross-layer interference in the dense small cell network scenario, we proposed a dense small cell interference management mechanism that combines enhanced inter-cell interference coordination and coordinated multi-point joint transmission, Point joint transmission to the user’s link, the configuration of almost blank subframes and the allocation of resource blocks, and maximizes the throughput of the system under the premise of ensuring the lowest user rate.The simulation results show that, compared with the enhanced inter-cell interference coordination The interference management method, joint enhanced inter-cell interference coordination and cooperative multi-point joint transmission interference management method further improves the network throughput and improves the spectrum utilization.
