一种LTE系统中计算CFI值的方法木
Method to calculate CFI value used in LTE system
摘要
Abstract
This paper investigated the problems of information redundancy for carrying PDCCH transmission and inefficiency for detecting PDCCH blindly in LTE system. Proposed a modified method of calculating CFI value. Before multiplexing, this method distributed the rate-matching value with the length of 1/2/4/8 CCE to each PDCCH in decreasing order. The simulation results show that this method can effectively eliminate the redundant information and reduce the average numbers of PDCCH blind detection.关键词
