Abstract

Recent works have validated the possibility of energy efﬁciency improvement in radio access networks (RAN), depending on dynamically turn on/off some base stations (BSs). In this paper, we extend the research over BS switching operation, matching up with trafﬁc load variations. However, instead of depending on the predicted trafﬁc loads, which is still quite challenging to precisely forecast, we formulate the trafﬁc variation as a Markov decision process (MDP). Afterwards, in order to foresightedly minimize the energy consumption of RAN, we adopt the actor-critic method and design a reinforcement learning framework based BS switching operation scheme. In the end, we evaluate our proposed scheme by extensive simulations under various practical conﬁgurations and prove the feasibility of signiﬁcant energy efﬁciency improvement.
