“…These schemes are classified into coordination-based and receiver-enhancement schemes. For the former, multiple BSs or UEs cooperate to avoid or mitigate CLI such as clustering [110,111], coordinated scheduling [112,113], coordinated power control [114,115], coordinated beamforming [116,117], and UL/DL configuration [118,119]. For the latter, CLI is mitigated by advanced interference suppression and cancelation algorithms at a receiver, such as interference rejection combining via spatial dimension [120,121], joint maximum likelihood detecting signal and interference [122], and interference cancelation [123].…”

The evolution of the fifth-generation (5G) new radio (NR) has progressed swiftly since the third generation partnership project (3GPP) standardized the first NR version (Release 15) in mid-2018. Nowadays, the world’s leading carriers are competing to provide various commercial services over 5G networks. Looking ahead to 2025 and beyond, it is expected that over 6.5 million 5G base stations will be installed to offer services to over 58% of the world’s population via over 100 billion 5G connections. Following the rapid development of 5G, an increasing number of commercialization use cases will drive the 5G network to continuously improve performance and expand capabilities. Hence, it is the right time to consider a well-defined framework and standardization for 5G NR evolution (5G-Advanced) to support commercialization between 2025 and 2030. First, this study addresses the key driving forces, requirements, usage scenarios, and capabilities of 5G-Advanced; then, it highlights the main technological challenges and introduces the top 10 promising technological directions in detail. Finally, other fascinating technological directions in 5G-Advanced are shortly mentioned.

“…On another side, and away from the power efficiency targets, the feasibility of the URLLC latency and reliability requirements is investigated for macro deployments with frequency division duplex (FDD) [6], time division duplex (TDD) [7], and for industrial factory TDD deployment [2], respectively. Furthermore, smarter scheduling algorithms [8,9] are vital to achieve the challenging URLLC targets, particularly in coexistence deployments with various quality of service (QoS) classes on the same spectrum. However, there is lack in the state-of-the-art literature on the performance cost, i.e., radio latency and reliability, paid in order to fulfill a power efficient operation at the device side.…”

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.
