Grant-Free Non-Orthogonal Multiple Access: A Key Enabler for 6G-IoT

23 Mar 2020 Abbas Rana Huang Tao Shahab Basit Shirvanimoghaddam Mahyar Li Yonghui Vucetic Branka

The proliferating number of devices with short payloads as well as low power budget has already driven researchers away from classical grant-based access schemes that are notorious for their large signalling overhead as well as power-consuming retransmissions. Instead, light-weight random access protocols have been re-investigated and their throughput has been improved in orders of magnitude with sophisticated yet still low-complex transceiver algorithms...
