HetNet中基于功率控制的动态增强小区间干扰协调方案
Dynamic Enhanced Inter-cell Interference Coordination Scheme Based on Power Control in HetNet
摘要
Abstract
Inter-cell interference coordination management scheme cannot satisfy the bandwidth rate and Quality of Service(QoS)requirement of interference source and interference network in heterogeneous cellular network.Aiming at the characteristics of heterogeneous cellular network and wireless communication mechanism,a dynamic enhanced inter-cell interference coordination scheme is proposed.According to the actual situation of the current network load,the optimal ratio of Lower Power-Almost Blank Subframe(LP-ABS)can be determined.The global interference situation of area users is extended through the residential area,and the optimal transmission power of the macro base station in the LP-ABS state is obtained,which is used in transmit power of macro base station.The maximum interference value of user tolerant macro base station is used to decide whether to perform LP-ABS ratio optimization or not to the next scheduling cycle.Experimental results show that on the basis of ensuring the overall throughput of the system is not too large,the proposed scheme can effectively guarantee the rate of the entire network users and QoS need,solve the problem that the high proportion of ABS leads to low performance for the user of interference source network,and improve overall communication network performance from multiple angles.关键词
