Holographic video communications epitomize a paradigm shift within the domain of visual communications. Arising from the amalgamation of advancements in optics, computational algorithms, and display technologies, holography transcends the confines of conventional communication modalities. The capacity to construct three-dimensional, lifelike depictions of information heralds unprecedented frontiers in telepresence, data visualization, and user interaction. In recent years, concerted efforts within relevant domains have propelled remarkable advancements in holographic displays, imaging, and telepresence, solidifying holography's status as a disruptive force across diverse sectors. From healthcare and education to entertainment and collaborative workspaces, holographic video communications are fundamentally reshaping our perceptual and interactive engagement with information, meriting acknowledgment as a major component of the 6G Vision outlined in International Mobile Telecommunications (IMT), towards 2030.

Beyond immediate applications, holographic video communications signify a departure from the status quo, prompting researchers and engineers to innovate across disciplinary boundaries. The confluence of hardware and software advancements has engendered an auspicious juncture to explore the comprehensive gamut of possibilities that holography affords to communication systems. This includes efficaciously addressing high-bandwidth and low-latency requisites, prognosticating future user behaviors, exploring holographic video features for communication enhancement, and potentially drawing upon semantic communication, artificial general intelligence, and large language models to further enhance holographic video communications.

Hence, the objective of this Special Issue (SI) is to provide a platform for both academic and industry researchers to disseminate their research findings pertaining to holographic video communications for both indoor and outdoor scenarios. Therefore, this SI aims to bring together researchers from both academia and industry to introduce a compendium of recent advances in holographic video communications. Topics of interest include but are not limited to:

• Resource allocation for holographic video communications.
• Edge computing for holographic video communications.
• QoS and QoE metrics for holographic video communications.
• Green holographic video communications.
• Cross-layer design for holographic video communications.
• User behavior predictions for holographic video communications.
• Human-in-the-loop for holographic video communications.
• Centralized, decentralized, and distributed management of holographic video communications. 
• Novel architectures for holographic video communications.
• Semantic communications for holographic video communications.
• Integrated sensing and communications for holographic video communications. 
• Artificial general intelligence and large language models for holographic video communications.
• Privacy and security for holographic video communications.
• Blockchain and cryptography for holographic video communications.
• Quantum computing for holographic video communications.
