In this study, the minimum transmission power of each femtocell user in a two‐tier network,
in which femtocells and macrocell use the spectrum simultaneously, is investigated. That is …

In this study, a power allocation scheme for two‐tier femtocell networks is proposed to
maximise the user utilities constrained with satisfactory quality of service, where femtocell …

In this paper, we focus on optimal power allocation for uplink transmission in two-tier
femtocell networks, where femtocells share the same frequency with macrocells. Due to …

In this paper, a two-tier uplink femtocell network operating in orthogonal frequency-division
multiple access is investigated. Femtocell base stations endowed with cognitive capacity …

This paper studies a robust uplink power control scheme with imperfect channel state
information (CSI) in two-tier femtocell network systems. Aiming at enhancing the system's …

Femtocells promise to improve the quality of indoor wireless communications substantially.
However, a serious interference problem arises with universal frequency reuse. In this …

In this paper, the resource scheduling and power control strategy is studied for a two-tier 5G
network system, which is comprised of a central macrocell and several small cells. Because …

Cellular networks' endurance limitations are in constant abatement as extra numbers of
cellular phone users are persistently occupying the resources of the network. Consequently …

Future cellular communication will relentlessly and incessantly hinge upon heterogeneous
network due to its' capabilities in maintaining lofty capacity figures. It also strengthens the …

This paper investigates the power allocation for femtocells which share the same frequency
with macrocell. Macrocell base station protects itself by price-based interference …
