Frame Structure and its Performance Analysis of Fractional Frequency Reuse
Li Yanchun · 2010
Aiming at the increasing requirement of interference mitigation in wireless communiation system,this paper raised a new style of frame structure design—Time-frequency division fractional frequency by reallocating subcarriers in frames.This new method integrates the modes of time division and frequency division on assigning resource blocks after modeling system capacity.The corresponding frame structure has a more precise granularity for adjustment compared with tradition fractional frequency reuse pattern.The results of simulation validate its advantages on system fairness and throughput of edge users,with the cost of slight capacity drop of the entire system.
