“…Numerical evaluations indicate that the proposed cell association rule provides almost 60% latency reduction, as compared to its standard, radio-exclusive counterpart. [9] a) Focusing on a MEC-enabled HetNet, a novel concept is introduced, UE-cell association metric, which evaluates the proximity of MEC resources to an appropriate UE. b) To showcase the benefits of the proposed association rule, an Extended-Packet Delay Budget (E-PDB) metric is introduced, which is a single link latency consisting of the radio transmission time of an input packet between the connected eNB in the UL and the UE, along with the execution time of a given task at the MEC host.…”

One of the underlying challenges in infrastructure-based multi-cell wireless networks is ensuring the proper association of a particular mobile User Equipment (UE) to the appropriate base stations (BSs). In the network terminology, this is usually referred to as cell association, user association, cell selection, or BS assignment. For now, the term cell association will be used for further discussion within this paper. In a wireless network with dense deployment of the base stations (BSs), the number of potential BSs with which a UE can be associated increases significantly with the increasing network complexity. The network densification demands the need for designing optimal or distributed cell association schemes. This is because, in case of improper association of UEs with BSs, it may result in increased interference, reduced throughput, inefficient energy consumption, load imbalance and higher latency in both uplink and/or downlink. 5G cellular networks aim to improve the connection speed and provide ultra-low latency through heterogeneous environments. While maintaining these parameters, the Quality of Service (QoS) needs to be maintained along with a sustained data rate. In such a case, the design of efficient cell association scheme for smooth flow of the traffic in the network is a real challenge which needs to be tackled. The aim of this paper is to study cell association techniques for 5G and beyond wireless networks, analyze the benefits of the methods and propose evolved and better solutions for cell association schemes.

“…Mobile edge computing (MEC)seems to be fit for reducing the latency. The stringent latency requirements are satisfied by MEC technology to the cellular network architecture [8], [9]. By means of pushing the cloud services to the edge of the whole network, the vehicle's mobile applications are offloaded to edge devices rather than the remote cloud platform anymore [10].…”

Nowadays, for improving the increasingly crowded traffic conditions, internet of vehicles (IoV) emerges. In IoV, the increase of smart vehicle applications produces computation-intensive tasks for vehicles. However, it is tough for vehicles to meet the demands required by tasks thoroughly due to the limited computing capacity deployed in vehicles. To address this challenge, the vehicle-to-everything (V2X) communication is a promising technology to support edge computing transmitting tasks across vehicles. By employing vehicle-to-infrastructure communication (V2I) and vehicle-to-vehicle communication (V2V), the origin vehicle seeks the feasible routes of offloading the computing tasks to the edge node (EN). In this paper, a computation offloading method which employs V2X technology for data transmission in edge computing, named V2X-COM, is proposed. Technically, the routing of the computing tasks is determined first. Then, non-dominated sorting genetic algorithm III (NSGA-III) is adopted to generate balanced offloading strategies. Furthermore, simple additive weighting (SAW) and multiple criteria decision making (MCDM) are employed to seek out the optimal offloading strategy. Finally, experimental evaluations are conducted to prove the validity of V2X-COM.

“…At the same time, a limitation of heterogeneous networks (HetNets), is the large load imbalance among multiple tiers stemming from differences in inter-tier resource availability. To remedy such issues, MCA can be complemented by multi-access edge computing (MEC) technology, which provides an open, lowdelay packet processing environment, in close proximity to end users [13]. However, focusing on HetNets and considering latency-intolerant applications, where the UEs have the option to delegate the execution of demanding tasks at a MEC server (e.g., physically co-located with a gNB), the application of conventional cell association is non-optimal, and a computationally-aware, DUDe-based UE-cell association rule needs to be applied, instead, as will be elaborated in Section III.C of the paper.…”

Multi-channel access is a family of multi-service radio resource management solutions that enable a user equipment to aggregate radio resources from multiple sources. The objective is multi-fold: throughput enhancement through access to a larger bandwidth tailored for enhanced mobile broadband, reliability improvement by increasing the diversity order and/or coordinated transmission/reception tailored for ultra-reliable low latency communication service classes, as well as flexibility and load balancing improvement by decoupling the downlink and the uplink access points, for both service classes. This paper presents several multi-channel access solutions for 5G New Radio multi-service scenarios. In particular, throughput enhancement and latency reduction concepts like multi-connectivity, carrier aggregation, downlink-uplink decoupled access and coordinated multi-point connectivity are discussed. Moreover, novel design solutions exploiting these concepts are proposed. Numerical evaluation of the introduced solutions indicates significant performance gains over state-ofthe-art schemes; for example, our proposed component carrier selection mechanism leads to a median throughput gain of up to 100% by means of an implicit load balance. Therefore, the proposed multi-channel access solutions have the potential to be key multi-service enablers for 5G New Radio.
