Center node: "noma versus oma in finite blocklength regime link layer rate performance"
  Abstract: In this paper, we investigate the latency performance comparison of non-orthogonal multiple access (NOMA) and orthogonal multiple access (OMA) in finite blocklength regime. In this regard, we derive the achievable effective capacity of a two-users NOMA network, and its OMA counterpart, under delay quality-of-service constraints. We, then, obtain closed-form expressions for the achievable effective capacity of the weak and strong users in Rayleigh fading channels. Through simulations, we show that at low signal-to-noise ratios (SNRs), the OMA user with better channel condition outperforms both NOMA users. The comparative analysis of total link-layer rate shows that at high SNRs, when the delay exponent is loose, the total link-layer rate of NOMA with finite blocklength outperforms the one of OMA.
