The problem of joint power and admission control (JPAC) is a critical issue encountered in
underlay cognitive radio networks (CRNs). Moving forward towards the realization of Fifth …

In this paper, we study how to maintain the communication quality for high-speed users by
utilizing array processing techniques. In conventional phase-array approaches, the phase …

Reconfigurable intelligent surfaces (RISs) have emerged as a game-changing technology to
improve wireless network performance by intelligently manipulating and customizing the …

This paper studies the joint multislot design of user scheduling and precoding to minimize
the time needed to serve all the users for unicast and multicast transmission in single-cell …

Base station (BS) activation is a widely-used approach to alleviate the system power cost for
device maintenance. However, frequently switching on/off BSs may also introduce extra …

In this paper, we study the joint admission control and beamforming problem within a
network where one multi-antenna base station tries to serve multiple single-antenna users …

The problem of joint power and admission control (JPAC) is a critical issue encountered in
underlay cognitive radio networks (CRNs). Moving forward towards the realization of Fifth …

These scenarios are of relevance and are already being considered in current and
upcoming standards including 4G and 5G. This thesis begins by presenting the necessity of …
