N2 - In this paper, we investigate the uplink transmission performance of URLLC in multi-cell interference channel, which is characterized by the delay-bound violation probability under given end-to-end (E2E) latency bound. To avoid extra channel estimation and feedback overheads, we assume that each device transmits with fixed rate and power, without the knowledge of instantaneous channel state information (CSI). Moreover, the statistical queuing behaviour of each device is described by the tool of stochastic network calculus. Due to the stringent performance metrics and short codeword blocklength of URLLC, we develop a performance optimization framework to maximize the transmission reliability of URLLC in the finite blocklength regime, via optimizing the fixed transmission rate. Numerical and simulation results demonstrate the effectiveness of our proposed performance optimization framework, in terms of improving the transmission reliability of URLLC.
