Does a macro base station need a hibernation scheme?

In addition to EE, considering that the macro base station will have additional energy consumption used for user connectivity, the hibernation scheme presented by Yang et al. aims to decrease the energy consumption of the cellular network by utilizing the support of SBS.

Does a base station sleep strategy affect EE?

This is because this paper proposes a base station sleep strategy that directly impacts EE and enhances the ratio of the overall system transmission rate to power consumption. In the final EE results are better than the other two methods.

Does base station sleep affect grade of service index?

To incorporate practical factors in base station sleep, studied the system energy consumption and grade of service under three base station sleep schemes and proposed an analytical method with high robustness, scalability, and computational efficiency to evaluate the grade of service index.

Is base station sleep technology a viable solution for wireless cellular networks?

Moreover, UDNs systems frequently experience substantial energy consumption challenges, with base stations representing over 80% of the overall energy expenditure in wireless cellular networks. In response to these challenges, base station sleep technology is increasingly seen as a promising solution .

How to reduce power-intensive base stations?

To address the issue of power-intensive base stations, proposed a combined approach involving base station sleep and spectrum allocation. This approach aims to discover the most efficient operating state and spectrum allocation for SBS to minimize power consumption and network disturbance.

How many operation modes can a base station have?

Chang et al. considered four operation modes of base stations to serve users with different needs and proposed a heuristic algorithm to switch as many base stations as possible to low-energy operation mode while the Quality of Service (QoS) of high-demand users is guaranteed.
