摘要
Different from earlier generation changes, the 5th generation of cellular communications (5G) will not only considerably improve the telecommunication services currently offered to the end users, but it will enable the support of evolved services tailored for other industries and humankind as such, for instance vehicular safety and transport system efficiency, industrial control, eHealth applications, etc. Accordingly, 5G sidelink have been considered to be one of native components in 5G in order to provide direct inter-device communications. To take advantage of such direct communications, techniques for control signaling improvement are proposed, including group based RACH access, multi-connectivity based service continuity management, and context aware group mobility management. In addition, to improve 5G sidelink data communication efficiency, techniques for 5G proximity-based service in ultra-dense networks have been evolved such as 5G proximity-based service for IoT, cooperative transmission and content caching. Simulation evaluation has been made to highlight the benefits of these techniques.
