  The deployment of multi-access edge computing (MEC) is paving the way towards
pervasive intelligence in future 6G networks. This new paradigm also proposes
emerging requirements of dependable communications, which goes beyond the
ultra-reliable low latency communication (URLLC), focusing on the performance
of a closed loop instead of that of an unidirectional link. This work studies
the simple but efficient one-shot transmission scheme, investigating the
closed-loop-reliability-optimal policy of blocklength allocation under
stringent time and energy constraints.
