Blocklength Minimization in NOMA Systems with Hybrid Long and Short Packets

Abstract

We consider a specific optimization problem in the downlink non-orthogonal multiple access (NOMA) system with hybrid short and long packets where the blocklength minimization of the short packets is the main goal. In particular, a cognitive-radio (CR)-inspired NOMA setup is assumed where the near user with stronger channel and long packet is guaranteed a minimum throughput whereas the far user with weaker channel is receiving sequence of short packets over the period of the long packet and seeks to minimize the transmission latency of each packet bearing the same amount of information. This is in line with certain kinds of IoT networks serving mixed traffic where users may have diverse service requirements and delay is critical in some applications. By solving the optimization problem, it is found that NOMA can offer smaller transmission latency on average for the short packets in comparison with its orthogonal-multiple-access (OMA) counterpart in such hybrid system.
