Technology Trends for Massive MIMO towards 6G

In addition, several evolutionary features and pioneering trends for massive MIMO have gradually emerged in recent years, which are expected to reshape the future 6G wireless networks and networks. More specifically, the capabilities and success of future massive MIMO systems can be enabled and enhanced by combining other innovative technologies, architecture, and policies such as intelligent omni-surfaces /intelligent reflecting surfaces, THz communications, cell free architecture, and cell-free architecture.

Joint Intra/Inter-Slot Code Design for Unsourced Multiple Access in 6G Internet of Things

The technology for massive, low-power, and uncoordinated Internet-of-Things in the 6G wireless network is the technology for massive, low-power, and uncoordinated Internet-of-Things, boosting connectivity and energy conservation on a guaranteed basis. This paper introduces a UMA code scheme based on the T-Fold IRSA model, based on the T-Fold IRSA model by using joint Intra/internal code design and optimization. We develop a joint intra/inter-slot coding parameter optimization algorithm to minimize the SNR requirement at a predicted system packet loss rate based on the error event decomposition and density evolution study.

Modeling and Analysis of 6G Joint Localization and Communication under Hardware Impairments

In the sixth generation communication technologies, localization is thought to be a key enabler to satisfy the needs of collaboration and context-aware services. While this effect can be dismissed at lower frequencies, where HWIs are less frequent, and localization standards are not stringent, modeling and analysis efforts are needed for high-frequency 6G bands to determine localization error due to HWIs. We also looked at the effects of individual and general HWIs on communication in terms of symbol error rate, complementary to the localization review. The delay estimates would have the most significant negative influence on SER, with only the angle estimation causing marginal decline in SER results.

Semantic Data Sourcing for 6G Edge Intelligence

Edge intelligence refers to the widespread deployment of machine learning and artificial intelligence techniques at the network edge to power many new applications ranging from sensing to auto-pilot. To solve the bottleneck, we recommend a new framework of SEMantic DAta Sourcing for finding semantically identical data sources to enable edge-intelligence operations. We discuss a set of machine learning based semantic matching strategies aimed at various edge-intelligence use cases as the main component of SEMDAS.

Holistic Network Virtualization and Pervasive Network Intelligence for 6G

We examine the evolution and potential of network architecture in this tutorial paper, as well as suggest a new conceptual architecture for the 6th generation networks. From the aspects of service delivery and service demand, respectively, to the inclusion of service-centric and user-centric networking, the holistic network virtualization consists of network slicing and digital twin. In both the perspectives of networking for AI and AI for networking, respectively, the pervasive network intelligence integrates AI into future networks.

Power Control for 6G Industrial Wireless Subnetworks: A Graph Neural Network Approach

Wired connectivity for control operation in robots and production modules is expected to be replaced by wired connectivity for control operation in robots and production modules, according to Generation 6th Generation industrial wireless subnetworks. However, existing centralized power control solutions for centralized power control may require complete channel state information of all the desired and interfering links, which may be cumbersome and time-consuming to obtain in dense deployments. Graph Neural Networks' paper This paper introduces a novel method for central power control for industrial subnetworks based on Graph Neural Networks. Only the proposed method requires subnetwork positioning information, which is usually known at the central controller, and knowledge of the desired link channel increase during execution.

Design and Optimisation of High-Speed Receivers for 6G Optical Wireless Networks

To achieve multi-Gb/s data rates in 6G optical wireless access networks based on narrow infrared laser beams, a high-speed receiver with two main features is needed: a large aperture to gather the required optical strength and a wide field of view to avoid tight alignment issues. A low-complexity optimal solution is suggested for rate maximization as a non-convex optimization problem under constraints on the minimum required FOV and overall ADR dimensions.

Near-Field Sparse Channel Representation and Estimation in 6G Wireless Communications

Future 6G wireless communications in the near-field area are expected to operate in the near-field area due to the use of extremely wide antenna arrays and high-frequency signaling. In this case, the spherical wave estimation, which takes into account both the user angle and distance, is more accurate than the conventional planar one, which is only related to the user angle. The user distance is included in the dictionary as unknown quantity, so the number of dictionary columns depends only on the angular space division. The angular-domain sparse vector can be almost recovered after a few iterations, according to our review. Finally, experiments in multi-user communication scenarios support the superiority of the proposed near-field channel sparse representation and estimation over the existing polar-domain method in channel estimation error.

Multi-band transparent optical network planning strategies for 6G-ready European networks

As long-distance network operators upgrade core optical networks to accommodate 5G services, development and standardization efforts for 6G have began. A multi-period multi-band transparent optical network planning study on three European networks is conducted, utilizing two deployment methods: namely, customizable bandwidth variable transceivers and transparent IP over wavelength division multiplexing. In comparison to transparent IPoWDM solutions, we also found that the CAPEX-per-bit of deploying Flex-BVTs is up to 12% lower when compared to transparent IPoWDM solutions, according to a simple Capital Expenditure estimate.

6G enabling FSO communication system employing integrated PDM-OAM-OCDMA transmission: impact of weather conditions in India

Due to its ability to produce high data rates with a high degree of assurance, free space optics transmission has gaining attention. In addition, using multiplexing methods with FSO makes it capable of coping with the high number of traffic reports and supporting the 5G and 6G wireless network needs. In addition, the effects of rainy, foggy, dusty weather, and the real weather for four major Indian cities with differing geographical locations are investigated and investigated. On the other hand, the shortest FSO range of 0. 105 kilometers is achieved when heavy dust storms are present. Srinagar achieves the fastest FSO link in India, 4. 2 kilometers, while Chennai city's longest range of 7 kilometers is recorded. In addition, this recently built transmission model has been optimized for use in 6G applications of FSO communication networks.
