“…A 6G architecture integrating digital twins, network slicing, and pervasive AI (Shen et al, 2021a) can be a foundation to immersive communications. Third, considering the diverse delay requirements of different XR, haptic communication, and holographic communication use cases, the Open-RAN (O-RAN) architecture featuring realtime, near-realtime, and non-realtime layers can benefit service differentiation in RAN management for immersive communications (Abdalla et al, 2022). Last, considering different user preferences and diverse user devices, a new architecture enabling usercentric networking, such as the everyone-centric architecture in , has a potential to empower immersive communications.…”

The sixth generation (6G) networks are expected to enable immersive communications and bridge the physical and the virtual worlds. Integrating extended reality, holography, and haptics, immersive communications will revolutionize how people work, entertain, and communicate by enabling lifelike interactions. However, the unprecedented demand for data transmission rate and the stringent requirements on latency and reliability create challenges for 6G networks to support immersive communications. In this survey article, we present the prospect of immersive communications and investigate emerging solutions to the corresponding challenges for 6G. First, we introduce use cases of immersive communications, in the fields of entertainment, education, and healthcare. Second, we present the concepts of immersive communications, including extended reality, haptic communication, and holographic communication, their basic implementation procedures, and their requirements on networks in terms of transmission rate, latency, and reliability. Third, we summarize the potential solutions to addressing the challenges from the aspects of communication, computing, and networking. Finally, we discuss future research directions and conclude this study.

“…The support of the multi-RATs is one of the key requirements of several vertical industries, including the maritime sector, because of the heterogeneous networks. The multi-connectivity combining different access technologies (e.g., cellular, satellite, Wi-Fi) continue to be enhanced for seamless connection in diverse service scenarios over 5G or 6G systems [ 39 , 40 , 41 , 42 ].…”

This study presents the architectural design and implementation of a multi-RAT gateway (MRGW) supporting dual satellite and terrestrial connectivity that enables moving maritime vessels, such as autonomous surface ships, to be connected to multiple radio access networks in the maritime communication environment. We developed an MRGW combining LTE and very-small-aperture terminal (VSAT) access networks to realize access traffic steering, switching, and splitting functionalities between them. In addition, we developed communication interfaces between the MRGW and end-devices connecting to their corresponding radio access networks, as well as between the MRGW and the digital bridge system of an autonomous surface ship, enabling the MRGW to collect wireless channel information from each RAT end-device and provide the collected data to the digital bridge system to determine the optimal navigation route for the autonomous surface ship. Experiments on the MRGW with LTE and VSAT end-devices are conducted at sea near Ulsan city and the Kumsan satellite service center in Korea. Through validation experiments on a real maritime communication testbed, we demonstrate the feasibility of future maritime communication technologies capable of providing the minimum performance necessary for autonomous surface ships or digitized aids to navigation (A to N) systems.
