摘要

摘要：针对毫微微蜂窝（femtocell）网络中多种业务（固定速率业务和可变速率业务）环境下如何公平分配毫微微蜂窝基站（femtocell base station

FBS）资源的问题，提出了一种基于比例公平算法的femto-macro异构网络资源分配算法。该算法以基于比例公平法则的可变速率用户的吞吐量为优化目标，并以每个用户的服务质量（quality of service

QoS）、FBS的下行传输总功率和宏蜂窝（macrocell）用户的跨层同频干扰门限值为约束组成优化问题。在上述资源分配最优化问题为凸优化问题的基础上，采用对偶分解算法进行求解。仿真结果表明，提出的算法在保证不同用户 QoS 的同时，不仅能够有效地公平分配资源给可变速率用户，而且降低了macrocell用户受到来自FBS的跨层同频干扰。

Abstract

The problem how to allocate the femtocell base station（FBS）resource fairly among multiple services （constant-rate services and variable-rate services）in femtocell network was focused on. Using the proportional fair to allocate the FBS transmit power for different variable-rate users was proposed to achieve fair allocated transmit rates in femto-macro heterogeneous network.The dual decomposition method was employed to find the optimal solution.Finally

the simulation results show that

besides protecting the individual QoS for each user

the proposed algorithm can not only provide fair resource allocation among variable-rate users

but also restrict the cross-tier interference to the MU.
