  Full-duplex (FD) technology is gaining popularity for integration into a wide
range of wireless networks due to its demonstrated potential in recent studies.
In contrast to half-duplex (HD) technology, the implementation of FD in
networks necessitates considering inter-node interference (INI) from various
network perspectives. When deploying FD technology in networks, several
critical factors must be taken into account. These include self-interference
(SI) and the requisite SI cancellation (SIC) processes, as well as the
selection of multiple user equipment (UE) per time slot. Additionally,
inter-node interference (INI), including cross-link interference (CLI) and
inter-cell interference (ICI), become crucial issues during concurrent uplink
(UL) and downlink (DL) transmission and reception, similar to SI. Since most
INI is challenging to eliminate, a comprehensive investigation that covers
radio resource control (RRC), medium access control (MAC), and the physical
layer (PHY) is essential in the context of FD network design, rather than
focusing on individual network layers and types. This paper covers
state-of-the-art studies, including protocols and documents from 3GPP for FD,
MAC protocol, user scheduling, and CLI handling. The methods are also compared
through a network-level system simulation based on 3D ray-tracing.
