Abstract:
We propose a time slot based transmission strategy,
referred to as adaptive coordinated napping (CoNap), for energy
saving in cellular networks under time-varying traffic demand.
In adaptive CoNap network, multiple neighboring base stations
(BSs) form a cluster and each BS operates in either a transmit
mode (TM) or a nap mode (NM) in each time slot. The
dynamic assignment of TM and NM to each BS is implicitly
coordinated among multiple BSs. This implicit coordination is
realized by a binary general flickering pattern matrix (FPM)
through adaptively selected mapping matrix (MM). To track the
time-varying traffic demand, we develop an adaptive algorithm
to dynamically select the appropriate MM from a predefined
MM set by taking into account the network quality of service
(QoS) requirement. Our numerical results based on a realistic
energy consumption model in a cellular network show that as
high as 40% saving can be achieved without compromising the
network QoS.
