Abstract
The growth of IoT demands efficient massive machine-type communication with short packet transmission. To address packet collisions in grant-free access, this paper proposes a multi-level decentralized power control (MLP-based) scheme for short packets. The scheme decouples the number of power levels from active devices, enabling effective multi-packet reception via SIC. Further, the paper derives a closed-form lower bound for the packet reception probability and analyzes the impact of key parameters. Numerical results show that the proposed scheme significantly outperforms the existing NOMA-based scheme.
