This presentation introduces the use of short-packet communications into non-orthogonal multiple access (NOMA) to achieve low latency in wireless networks. Specifically, the optimisation of transmission rates and power allocation is conducted to maximise the effective throughput of the user with a higher channel gain while guaranteeing the other user achieving a certain level of effective throughput. To demonstrate the benefits of NOMA, the performance of orthogonal multiple access (OMA) is analysed as a benchmark. It is shown that NOMA can significantly outperform OMA by achieving a higher effective throughput with the same latency. Moreover, it is found that the performance gap between NOMA and OMA becomes more prominent when the effective throughput targets at the two users become closer to each other. This demonstrates the benefits of the joint exploration of NOMA and short-packet communications with practical constraints.
