N2 - The Industrial Internet of Things (IIoT) has attracted considerable attention because of its capability in turning common objects into connective devices. In IIoT, Deterministic Networking (DetNet) is an important scenario that can provide the network layer ultra-low latency support. In this paper, we focus our attention on the asymptotic cross-layer analysis of delay-violation-probability and power tradeoff in DetNet. More specifically, we find that zero delay-violation-probability transmission cannot be achieved under causal channel status with finite average power consumption. To support the requirement of DetNet under casual channel status, we prove that zero delay-violation-probability transmission can be achieved through frequency diversity, the use of multiple antennas, and cooperative diversity. Under non-causal channel status, DetNet can be achieved when the hard delay constraint is more than one time slot. Moreover, we derive the optimal tradeoff between the delay-violation-probability and average power consumption under causal channel status, which is further verified through numerical simulations.
