The deployment of dense networks of small base stations represents one of the most
promising solutions for future mobile networks to meet the foreseen increasing traffic …

In mobile networks, base stations (BSs) have the largest share in energy consumption. To
reduce BS energy consumption, BS components with similar (de) activation times can be …

Real-time traffic in a cellular network varies over time and often shows tidal patterns, such as
the day/night traffic pattern. With this characteristic, we can reduce the energy consumption …

With the increasingly higher demand on radio access networks, problems such as serious
energy consumption and network load imbalance have aroused, catching more attention …

With the growing momentum around Open RAN (O-RAN) initiatives, performing dynamic
Function Splitting (FS) in disaggregated and virtualized Radio Access Networks (vRANs), in …

Advanced Sleep Modes (ASMs) correspond to a gradual deactivation of the Base Station
(BS)'s components in order to reduce its Energy Consumption (EC). Different levels of Sleep …

Recent works have validated the possibility of improving energy efficiency in radio access
networks (RANs), achieved by dynamically turning on/off some base stations (BSs). In this …

In this paper, we propose an online energy management strategy to minimize the
operational expenses incurred by cellular base stations powered by both renewable and …

The paper presents system level simulation results on future base station energy saving
using a time-triggered sleep model. The energy efficiency of future base station is compared …

In this paper, we investigate network sleep mode schemes for reducing energy consumption
of radio access networks. We first propose, using Markov Decision Processes (MDPs), an …
