Ultra-Reliable and Low-Latency Communication (URLLC) has attracted significant attention due to its potential in factory automation, telesurgery, and automatic driving. However, little attention has been paid to URLLC when the traffic arrival is random. In this paper, a random arrival oriented URLLC policy is investigated for Additive White Gaussian Noise (AWGN) channels. More specifically, we develop a queue-aware variable length channel coding scheme, in which the blocklength of channel coding is determined by the queue length. Further, from a cross-layer design perspective, we present the optimal tradeoff between latency and power consumption given the reliability constraint. To this end, we formulate a Markov chain to attain the delay and power consumption, based on which a Linear Programming (LP) problem is formulated to minimize the latency under a power constraint. By solving the derived LP problem, we obtain the optimal variable-length coding policies with a threshold-based structure imposed on the queue length. |
