Abstract
Nowadays the development of internet of things (IoT) has become the next major growth point of wireless communication. And narrow band has become a new trend in the development of IoT. Achieving massive connectivity and ever-increasing network capacity has become an important subject of our research. We find that sparse code multiple access (SCMA), a type of non-orthogonal multiple access, is supposed to meet these needs, but it can hardly apply to NB-IoT because narrow band does not have the ability of spread spectrum. On this basis, we introduce SCMA into time domain, named T-SCMA, for NB-IoT. By multiplexing SCMA in the time domain and defining a MAC frame structure, we can significantly improve both connectivity and network capacity, ultimately obtain a much higher throughput property gain over time division multiple address (TDMA).
