Due to the shortage of wireless spectrum resources , multi-level network and high-level frequency re-use are used frequently .All these causeco-channel interference and poor transmission .To improveperformance , firstly, based on 3GPP protocol, the G factor is derived bytwo methods;Secondly,according to the effective nes-sandpotential risks , wechoose RSRP to calculate by analyzing and comparing laboratory data .At last, we use the factor to coordinate the allocationin order to reduce collisionby adjusting scheduling time .Simulation is carried out with two kinds of standard network structure , and the parameters are limited by real network .The results show that the study can improves throughput , and the gain is more obvious in dense .The theoretical basis for co-channel net-work was increased .%由于无线频谱资源日益短缺，多层次组网、高复用方式频繁应用造成同频干扰现象时有发生，导致网络传输不畅。为得到较好改善，首先从3GPP已有协议出发，采用两种方案推导获取关键参数Geometry因子；其次针对网络有效性、规避潜在风险性，通过分析对比及实验室验证，确定RSRP作为其计算模式；最后将该因子应用于已有系统，以减小资源碰撞为目的，调整调度时序以协调资源分配。仿真以两种网络标准拓扑进行，并依据网络实际探测能力进行限制，结果表明，可以达到提升系统吞吐量的目的，且密集组网场景下增益提升更明显。
