Overview
Until 4G services, high throughput even in cell edge areas and seamless connectivity are considered as key technical requirements. However, 5G services focus on the enhancement of end users’ experience instead of throughput itself. That is, the end users’ perspectives are more emphasized than network service providers’ technical aspects.
With 5G wireless networks, users can experience hologram contents or 3D high quality multimedia services based on virtual reality (VR) and augmented reality (AR) and mixed reality (MR) technologies. Low latency communication networks as well as ultra-high throughput is definitely necessary for users to experience realistic interaction with diverse interactive real-time multimedia services. Accordingly, Tactile Internet, i.e., the Internet with the characteristic of low delay for enabling the transmission of tactile information, has attracted attention as one of the core functions of 5G mobile communications. The tolerable delay-time for Tactile Internet has been set as 1 ms, so that user may not have an unnatural feeling when receiving tactile information through the Internet, since tactile sense is most sensitive to delay-time among the 5 human senses. The minimization of delay-time between communication systems to less than a few milliseconds will improve the communication quality felt by end-users. Intelligent transportation systems with autonomous vehicles and robot applications for smart industry and medical areas require such low latency in the context of Tactile Internet. In 3GPP to develop IMT-2020 standards for 5G includes the ultra-reliable low-latency communications (URLLC) as one of key technical aspects of 5G.
Therefore, this special issue invites research papers to share latest research insights and present emerging results on the Tactile Internet and/or URLLC. Topics of interest for this special issue include, but are not limited to the following.
1. Networking architecture and technologies
