Method to calculate CFI value used in LTE system
一种LTE系统中计算CFI值的方法*

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.
