LTE-A上行链路联合功率控制方案
Joint power control scheme for LTE-A uplink
摘要
Abstract
Power control for uplink in LTE-A played a significant role in compensating the path loss of intra-cell users and mitigating inter-cell interference.Considering the lower power value of edge users might lead to the wrong demodulation of resource block(RB) in uplink,this paper proposed an improved power control scheme combined with open loop power control and closed loop power control in PUSCH.With the closed loop power control scheme,this work improved the power headroom report-based algorithm,which took the power margin for each RB into consideration.And it also set the range of target signal to interference plus noise ratio reasonably.While this paper also further specified the two open loop parameters that path loss compensation factor and a cell-specific parameter.Experimental results show that in terms of cell throughput,the improved program performs better.关键词
