摘要

The multiple access issue caused by the massive connections of devices is the key design aspect in the machine-to-machine communication system. As an uncoordinated access scheme, coded slotted ALOHA (CSA) is proposed and well studied to enable random access and high throughput simultaneously with no grant process. It shows efficient performance when the payloads are small. However, the CSA does suffer from the stopping set problem: the Successive Interference Cancellation (SIC) decoding process of CSA would come to a jam when normalized offered traffic is large. We propose an enhanced scheme based on CSA, that is, adding a novel physical layer feedback scheme on CSA to initiate the SIC decoding when there is no degree-1 slot. Considering the overhead of the feedback, simulations show that the proposed scheme can increase the number of successfully accessed devices in one frame.
