State‐of‐the‐Art of Sparse Code Multiple Access for Connected Autonomous Vehicle Application

Considering the dramatic growth of traffic, 5G communication technology is proposed to support massive connectivity with a large number of devices. Connected autonomous vehicles (CAVs) network is one of the important future applications that can benefit from 5G. Sparse Code Multiple Access (SCMA), as a promising technique in 5G wireless communication networks, has recently received lots of attention. This chapter aims to investigate the fundamental principles of SCMA technique, summarize the state‐of‐the‐art of SCMA technology and its application, and point out how the current research work can contribute to the quality of experience for drivers and passengers. It identifies the gaps in the adoption of SCMA in vehicular communication systems. The chapter also identifies the challenges and research gaps for the provision of massive connections with low latency and high reliability in the 5G communication system for CAVs.
