  Dynamic time division duplexing (TDD) is envisioned as a vital transmission
technology of the 5G new radio, due to its reciprocal propagation
characteristics. However, the potential cross-link interference (CLI) imposes a
fundamental limitation against the feasibility of the ultra-reliable and low
latency communications (URLLC) in dynamic-TDD systems. In this work, we propose
a near-optimal and complexity-efficient CLI suppression scheme using orthogonal
spatial projection, while the signaling overhead is limited to B-bit, over the
back-haul links. Compared to the state-of-the-art dynamic-TDD studies, proposed
solution offers a significant improvement of the URLLC outage latency, e.g.,
-199% reduction, while boosting the achievable capacity per the URLLC packet by
+156%.
