上行小小区网络采用累计分布函数的资源分配
Cumulative distribution function based resource allocation in the uplink of the small cells network
摘要
Abstract
In order to reduce co-channel interference and improve spectrum efficiency in the uplink of the small cells network,the joint cumulative distribution function based user scheduling and distributed power allocation are proposed.In the proposed scheduling,the small cell base station selects the user having the largest cumulative distribution function value.The selected user adjusts its transmit power to reduce the co-channel interference to other cells based on a pre-determined threshold.We then transform the original global optimization problem into a distributed problem and attain the optimal transmit powers through Lagrangian dual decomposition.Simulation results show that the simplified algorithm has the performance hearly identical to that of the conventional optimal power allocation algorithm.关键词
