title = "Random back-off mechanism for contention-based uplink of SCMA",
abstract = "In the 5G mobile communication network, massive connectivity is one of the requirements. In this paper, we study the SCMA contention-based uplink to achieve massive connectivity. SCMA can provide a higher overload with limited resources. On this basis, the uplink users adopt the mechanism of random back-off to contend to access the system. The number of access users can be further increase. The traditional OFDMA and SCMA with a scheduling method were compared in the simulation. The simulation results show that our approach has a good performance in the number of access users and throughput over a certain limit.",
