Short-Packet Downlink Transmission With Non-Orthogonal Multiple Access

Sun, Xiaofang; Yan, Shihao; Yang, Nan; Ding, Zhiguo; Shen, Chao; Zhong, Zhangdui


This paper introduces downlink non-orthogonal multiple access (NOMA) into short-packet communications. NOMA has great potential to improve fairness and spectral efficiency with respect to orthogonal multiple access (OMA) for low-latency downlink transmission, thus making it attractive for the emerging Internet of Things. We consider a two-user downlink NOMA system with finite blocklength constraints, in which the transmission rates and power allocation are optimized. To this end, we investigate...[Show more]
