In this paper, the authors consider the adoption of sleep modes for the base stations of a cellular access network, with the objective of reducing the amount of energy needed to serve users in periods of low traffic. They discuss the main issues arising with this approach, and they focus on the design of base station sleep and wake-up transients, also known as cell wilting and blossoming. The performance of the proposed procedures is evaluated in a realistic test scenario and the results show that sleep and wake-up transients are short, lasting at most thirty seconds.
