… The population representing the number of BSs is further reduced by shutting down
redundant BSs while an additional energy saving scheme based on day-night traffic profile is …

… cle we mainly focus on the radio resource management schemes for heterogeneous
networks that can address the ever-increasing SE, EE, and QoS demands for 5G wireless …

… , while maintaining the same user performance. We also analyse how a heterogeneous
network featuring energy efficiency (EE) schemes can have a lower energy consumption than …

… Further, we investigate the EE performance of mainstream network selection scheme for …
resource allocation and interference management in small cell heterogeneous networks. …

… In the following, we consider that all base stations in the heterogeneous networks operate
in … based scheme, we show that the location based and the average signal based schemes …

… , motivated by the heterogeneous traffic model proposed in conventional OFDMA networks
[29]… Therefore, in the following sections, we develop resource allocation schemes to tackle the …

… In this paper, we investigate the energy saving issue in a heterogeneous network (HetNet),
which is introduced to cellular radio networks to improve capacity and enhance coverage. A …

… network cell size and their layouts [21]. Heterogeneous networks are supposed to conserve
energy if … this aspect of limiting the energy consumption of networks. The power consumption …

… energy efficiency metrics can be the key measurement for the energy consumption in
heterogeneous networks… the sleep mode scheme and full function mode, we may derive the …

… and heterogeneous networks. Results are presented as overall energy reduction gains
