摘要：Although dynamic base station (BS) operation (switch off or sleep mode) schemes can improve energy efficiency in cellular networks, the quality of service (QoS) (e.g., service blocking and service latency) experienced by users may be significantly affected by these energy-efficient schemes. On the other hand, to guarantee user QoS, user equipment (UE) admission control has been studied extensively. However, these two important areas have traditionally been addressed separately. In this paper, we propose a common framework to jointly study dynamic BS operation and UE admission. Specifically, we introduce a novel concept of BS admission control, and propose an optimal joint BS-UE admission control scheme considering both dynamic BS operation and dynamic UE traffic. The proposed scheme can maximize energy efficiency while guaranteeing user QoS. Simulation results are presented to show the effectiveness of the proposed scheme.
