一种femto-macro异构网络多业务资源公平管理算法

doi:10.11959/j.issn.1000-0801.2015241

Abstract

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.

Key words: esource allocation, constant-rate user, variable-rate user, macrocell protection, proportional fair algorithm
