Special Issue Information

Dear Colleagues,

5G mobile network deployments are currently ongoing worldwide, while research and standardization continues to improve certain 5G features and limitations. Current standardization efforts for 3GPP release 18 (5G-Advanced) represents a major evolution in 5G, including enhancements in the areas of Artificial Intelligence and extended reality, which will enable highly intelligent network solutions that can support a wider variety of use cases than ever before. Based on previous knowledge and current trends, a new mobile network generation (6G) is expected around 2030, to address the new and evolving communication requirements of a fast-moving world. 6G is expected to include improved radio technologies probably at higher frequencies, enhanced Artificial Intelligence (AI) and machine learning (ML) techniques, expanded Internet of Things (IoT) networks, etc. Recent discussions refer to the path towards 6G as an evolution of 5G, proposing different approaches. This Special Issue aims at including a set of papers that identify these approaches, providing a fruitful field for thinking and debating.

Special Issue topics include but are not limited to:

  • Radio transmissions at very high frequencies;
  • Spectrum sharing;
  • Enhanced mobility support;
  • AI and ML towards 6G;
  • RAN and network management;
  • Ultra-reliable, low-latency communications;
  • Beamforming and MIMO advancements;
  • Advanced network designs for edge and cloud computing;
  • Enhancements for extended reality.

With the significant rise in demand for network utilization, such as data transmission and device-to-device (D2D) communication, fifth-generation (5G) networks have been proposed to fill the demand. Deploying 5G enhances the utilization of network channels and allows users to exploit licensed channels in the absence of primary users (PUs). In this paper, a hybrid route selection mechanism is proposed, and it allows the central controller (CC) to evaluate the route map proactively in a centralized manner for source nodes. In contrast, source nodes are enabled to make their own decisions reactively and select a route in a distributed manner. D2D communication is preferred, which helps networks to offload traffic from the control plane to the data plane. In addition to the theoretical analysis, a real testbed was set up for the proof of concept; it was composed of eleven nodes with independent processing units. Experiment results showed improvements in traffic offloading, higher utilization of network channels, and a lower interference level between primary and secondary users. Packet delivery ratio and end-to-end delay were affected due to a higher number of intermediate nodes and the dynamicity of PU activities. Full article

The 6G wireless systems are expected to have higher capacity, reliability, and energy efficiency than the existing cellular systems. Millimeter-wave (mmWave) frequencies offer high capacity at the cost of high attenuation and blockage losses. Reconfigurable intelligent surface (RIS) assisted mmWave networks consist of smaller antenna elements that control the propagation channel between the base station (BS) and the user by appropriately tuning the phase and the reflection of the incident electromagnetic signal. The deployment of RIS is considered to be an energy efficient solution to improve the coverage of regions with high blocking probability. However, if every BS is associated with one or more dedicated RIS, then the density of RIS increases proportionally with the density of BSs. Hence in this work, we propose RIS sharing mechanisms where multiple BSs share one RIS. We formulate resource allocation of RIS sharing in terms of time and the RIS elements as an optimization problem, and we propose heuristics to solve both. Further, we present detailed simulation results to compare time and the element based RIS sharing methods for various scenarios with the benchmark and the RIS system without sharing. The proposed time and element based RIS sharing methods improve throughput upto 53% and 25%, respectively, compared to the RIS system without sharing in specific scenarios. Full article
