【摘要】：该文为降低无线接入网的能耗,提出一种基于Benders分解的协作节能机制,通过协作基站选择和基站状态控制以解决基站休眠带来的弱覆盖问题。结合业务量分布和SINR空间变化建立协作基站的选择模型,用以找到合适的协作基站以及相应的休眠基站。并提出一个基于Benders分解的联合优化策略,控制基站活跃/休眠状态,实现网络容量与吞吐量间的平衡。仿真结果表明,该机制可在不增加发射功率的条件下实现覆盖补偿,并在至多42.6%的基站休眠时,仍能满足网络的基本性能要求。
[Abstract]:In order to reduce the energy consumption of wireless access network, a cooperative energy saving mechanism based on Benders decomposition is proposed. Through cooperative base station selection and base station state control, the weak coverage problem caused by the base station dormancy is solved. The selection model of the cooperative base station is established by combining the traffic distribution and the SINR space change to find the appropriate cooperative base station and the cooperative base station. A corresponding hibernation base station is proposed. A joint optimization strategy based on Benders decomposition is proposed to control the active / dormant state of the base station to achieve the balance between network capacity and throughput. The simulation results show that the mechanism can achieve coverage compensation without increasing the transmission power, and can still satisfy the network base when the most 42.6% of the base station is dormant. This performance requirement.
