LTE-A系统载波聚合情况下改进的PF算法
Improved proportional fair algorithm for LTE-Advanced system with carrier aggregation
摘要
Abstract
In order to improve the cell edge users throughput and fairness between all users, this paper proposed a cell edge user prior proportional fair algorithm. The subject of this algorithm was to allocate the RBs( resource blocks) of some component carriers to the cell edge users and cell center users with probability a and 1 - a respectively. After the allocation, it scheduled RBs by originally proportional fair algorithm. While the RBs of the other component carriers were scheduled by originally proportional fair algorithm directly. Simulation results indicate that this algorithm can fairly improve the cell edge users throughput and fairness between all users. In addition, it can adjust the cell edge users throughput and fairness between all users through controlling the size of a.关键词
