Can small base stations conserve grid energy in hybrid-energy heterogeneous cellular networks?

Abstract: Dense deployment of small base stations (SBSs) within the coverage of macro base station (MBS) has been spotlighted as a promising solution to conserve grid energy in hybrid-energy heterogeneous cellular networks (HCNs), which caters to the rapidly increasing demand of mobile user (MUs).

How can a small cell base station be used in a building?

An effective way to address this problem is to deploy small cell base stations (BSs) within buildings due to their small coverage and low transmission power such that an indoor UE can be served at a short distance and hence at low power.

Do cellular network operators prioritize energy-efficient solutions for base stations?

Recognizing this, Mobile Network Operators are actively prioritizing EE for both network maintenance and environmental stewardship in future cellular networks. The paper aims to provide an outline of energy-efficient solutions for base stations of wireless cellular networks.

Does a hybrid network consume more energy than a full-digital network?

The energy consumption of the network gets increases as the density of small cells rises. Certain findings as indicated above suggests that hybrid architectures in massive MIMO systems have much higher achievable EE, although their SE is lower than full-digital architectures.

Can hybrid-energy hcns maximize EE?

It is shown that the proposed scheme outperforms other schemes and can also maximize the EE in hybrid-energy HCNs.

Does a hybrid approach improve EE and SE performance in small cells?

For small cells in UDN, a hybrid approach optimizing both EE and SE is required with the constraints of high data rate and interference thresholds. It was observed that, with a slight decline in SE performance, the EE may be greatly enhanced.
