【摘要】：該文為降低無線接入網(wǎng)的能耗,提出一種基于Benders分解的協(xié)作節(jié)能機(jī)制,通過協(xié)作基站選擇和基站狀態(tài)控制以解決基站休眠帶來的弱覆蓋問題。結(jié)合業(yè)務(wù)量分布和SINR空間變化建立協(xié)作基站的選擇模型,用以找到合適的協(xié)作基站以及相應(yīng)的休眠基站。并提出一個(gè)基于Benders分解的聯(lián)合優(yōu)化策略,控制基站活躍/休眠狀態(tài),實(shí)現(xiàn)網(wǎng)絡(luò)容量與吞吐量間的平衡。仿真結(jié)果表明,該機(jī)制可在不增加發(fā)射功率的條件下實(shí)現(xiàn)覆蓋補(bǔ)償,并在至多42.6%的基站休眠時(shí),仍能滿足網(wǎng)絡(luò)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.
