This PhD thesis presents a comprehensive investigation into power control (PC)
optimization in cellular (CL) and cell-free (CF) massive multiple-input multiple-output …

The Internet of things (IoT) is one of the main use cases of ultra massive machine type
communications (umMTC), which aims to connect large-scale short packet sensors or …

As a critical supplementary to terrestrial communication systems, low-earth-orbit (LEO)
satellite communication systems have been gaining growing attention in recent years. In this …

In this chapter, we discuss the multiple access towards non-terrestrial networks. Section 3.1
introduces the current research directions of IoT and the motivation of proposing non …

This paper considers the problem of symbol detection in massive multiple-input
multipleoutput (MIMO) wireless communication systems. We consider hard-thresholding …

[en] In conventional satellite communication systems, onboard resource management
follows pre-design approaches with limited flexibility. On the one hand, this can simplify the …

High throughput, successive interference cancelation, higher cell edge spectrum efficiency,
and low latency are the main requirements for future generation technology. Non-orthogonal …

Mobile Edge Computing (MEC) is rapidly emerging as a vital component in the landscape of
cloud computing and next-generation network. It brings computation and storage resources …

In this paper, we study the transmission power allocation of the secondary base station to
the secondary user in cognitive radio networks when multiple primary users (PU) and …
