Summary:
Grant-free Non-Orthogonal Multiple Access (NOMA) scheme is considered a promising technique to enable massive Machine-Type Communication (mMTC) in 6G to provide massive connectivity to devices with different protocols. In a grant-free NOMA system, fast and efficient channel-power resource block selection is extremely important to guarantee communication quality for the rapidly changing communication environment, such as vehicle networks. To achieve that, we propose an uplink grant-free NOMA system using a laser chaos decision maker in this paper. In our proposed system, the channel-power resource block can be selected in real-time. Simulation results show the effectiveness of our proposed system in the probability of successful communication.
