“…• Advanced receivers: Compared to the coordinationbased CLI mitigation strategies used ahead by the transmitting device, the receiving end may suppress and eliminate incoming CLI. These methods necessitate data communication between cells in advance, but the CLI is minimized reactively by inserting advanced receivers [83]. Three kinds of interference suppression exist: interference suppression, maximum likelihood, and IC [84]- [86].…”

In unmanned aerial vehicle (UAV)-assisted wireless networks, the potential of the high probability of line-of-sight links could be a disadvantage for other nearby wireless networks because of interference caused by a UAV. For this reason, using interference mitigation techniques (IMTs) for UAV-assisted wireless networks is necessary to minimize interference effects. For instance, the mobility of UAVs gives a chance to manage interference better to avoid being a source of interference or being susceptible to interference. After the first-generation mobile network was introduced in the early 1980s, mobile communication systems were developed through several stages of evolution over the following few decades to satisfy rising demand and more stringent specifications. Different IMTs are needed due to these generations' differences. Unlike previous research, this research presents a systematic review of IMTs in the current and future UAV-assisted wireless networks and discusses their challenges. We also review the current research trends of UAV IMTs and their future insights. Our motivation for conducting this research is the need for a systematic review addressing these issues. In this systematic review, we use a more precise classification of the IMTs for UAV-assisted wireless networks. We classify them into four different techniques, namely, adaptive modulation and coding schemes, dynamic antenna pattern adjustment, dynamic transmit power control, and sub-channel scheduling. Moreover, we discuss the IMTs for UAVs using B5G wireless technologies such as intelligent reflecting surfaces, rate-splitting, super modular massive multiple-input multiple-output, Terahertz communications, holographic beamforming, blockchain-based spectrum sharing, and artificial intelligence and machine learning schemes. Furthermore, we identify the challenges of UAV IMTs and their open research directions such as wireless radio frequency spectrum scarcity, lack of networking scalability, beam distortion, resource-constrained management, and new sources of interference. We believe this research will help researchers choose the best technique to mitigate the interference effects in UAV-assisted wireless networks.

“…7) Flexible duplexing: Finally, 5G-Advanced will also study flexible duplexing (FDU) evolution, including enabling simultaneous UL and DL transmission on an unpaired carrier. FDU is envisioned to offer additional flexibility for latencythroughput demanding XR applications, as compared to the current TDD solution with either exclusive DL or exclusive UL transmission at any given time for each unpaired carrier per cell [15]. However, FDU imposes additional complexity on BSs and UEs.…”

Extended Reality (XR) is one of the major innovations to be introduced in 5G/5G-Advanced communication systems. A combination of augmented reality, virtual reality, and mixed reality, supplemented by cloud gaming, revisits the way how humans interact with computers, networks, and each other. However, efficient support of XR services imposes new challenges for existing and future wireless networks. This article presents a tutorial on integrating support for the XR into the 3GPP New Radio (NR), summarizing a range of activities handled within various 3GPP Services and Systems Aspects (SA) and Radio Access Networks (RAN) groups. The article also delivers a case study evaluating the performance of different XR services in state-of-the-art NR Release 17. The paper concludes with a vision of further enhancements to better support XR in future NR releases and outlines open problems in this area.

Energy efficiency is critical for future sustainable cellular systems. Power saving optimization has been a key part of the fifth generation (5G) new radio specifications. For 5Gadvanced and future 6G, with the anticipation of a trillion internet of things (IoTs) devices with non-rechargeable or lowdensity batteries, device power efficiency is rather essential. There are numerous contributions from industry and academia which present the potential power saving gains of the various 5G power saving techniques; however, there is a lack of art on the performance cost paid to achieve such power saving gains. Therefore, this paper presents a comprehensive evaluation of the radio latency and reliability cost, which is lost due to a certain 5G new radio power saving feature. A thorough review of the stateof-the-art 5G power saving techniques is introduced. Extensive system level simulations are performed to evaluate the latency and reliability cost of the considered power saving features. The paper offers valuable recommendations for supporting powerefficient latency-critical traffic for beyond 5G-advanced systems.
