“…Based on the Shannon capacity formula, for a given amount of data, the total transmit power can be reduced by enlarging the resource amount, hence reducing the transmit power spectrum density (PSD). Thus, some researchers have proposed to spread the data transmission on as many resources as possible to reduce the total power consumption [147]. However, this method is unsuitable for cell-edge users because a reduced PSD would lead to a larger channel estimation error, which will significantly impact the achievable transmission rate.…”

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.

“…Although POLITE's benefits are interesting, one of the main limitations of the original POLITE scheme [4] was the unawareness of packet delay budgets and its incapacity to enforce these. The more recent [5] formulates how packet delays can be matched, evaluating its performance in indoor factory (InF) scenarios [15], showing performance improvements in terms of system capacity, packet delays fulfillment, and reduced transmit power.…”

“…The more recent [5] formulates how packet delays can be matched, evaluating its performance in indoor factory (InF) scenarios [15], showing performance improvements in terms of system capacity, packet delays fulfillment, and reduced transmit power. However, in the previous works [4,5], only LA was under the scope of POLITE methods. Focusing on URLLC use cases, in this work we consider how POLITE can interact with user scheduling and resource allocation to minimize latency and increase reliability of latency-critical traffic.…”

“…In this work, we address the paradigm for (LA) and power allocation introduced in [4,5] to improve performance of wireless networks by leveraging all the available radio time-frequency resources of every cell. The Power Optimization for Low Interference and Throughput Enhancement (POLITE) in [4] exploits the significant underutilization of wireless resources of current systems [6]. By applying POLITE, each transmission can be stretched on a bigger amount of resources, allowing to reduce the transmit power while preserving the transmission's reliability.…”

One of the current (6G) wireless networks research’s trends is to investigate short distance and dense scenarios, where users are locally connected in sub-networks. Such use case is critical to support the advances of industrial internet of things or Industry 4.0 (I4.0), e.g. connecting an entire group of sensors and actuators of a robot. Therefore, schemes that can properly manage the interference must be deployed in practical systems to allow the promised performance advances of 6G. Targeting these high density scenarios, we describe the Power Optimization for Low Interference and Throughput Enhancement (POLITE) paradigm for link adaptation and power allocation, which leverages available radio resources to stabilize and reduce the interference. The baseline link adaptation schemes are compared with POLITE in their performance in a 3rd generation partnership project (3GPP) calibrated system level simulator for industrial scenarios. As services in industrial environments require high reliability under constrained delays, we propose different delay-aware formulations in the POLITE design. In this work, we provide solutions both for relaxed delay requirements and for latency critical traffic, whose delay must be minimized. In particular, in the latter case, we propose also modifications of user selection and resource allocation procedures to further improve the reliability and latency. Simulation results prove the benefits of POLITE in terms of increased throughput, fulfillment of relaxed and delay-critical requirements, with an overall reduced transmit power compared to the current baseline link adaptation schemes.

“…Also, rank adaptation can be used to adapt the number of spatial streams to the channel and interference condition [79]. Furthermore, power control leveraging unused resources in non-congested cells can be used to reduce the generated interference [80], and that is beneficial both for increasing throughput and serving traffic with moderate latency requirement, i.e., in the order of tens of ms [81].…”

The 6th Generation (6G) radio access technology is expected to support extreme communication requirements in terms of throughput, latency and reliability, which can only be achieved by providing capillary wireless coverage. In this paper, we present our vision for short-range low power 6G 'in-X' subnetworks, with the 'X' standing for the entity in which the cell is deployed, e.g., a production module, a robot, a vehicle, a house or even a human body. Such cells can support services that can be life-critical and that traditionally relied on wired systems. We discuss potential deployment options, as well as candidate air interface components and spectrum bands. Interference management is identified as a major challenge in dense deployments, which needs to handle also non-cellular types of interference like jamming attacks and impulsive noise. A qualitative example of interference-robust system design is also presented.
