  The ultra-reliable and low-latency communication (URLLC) is the key driver of
the current 5G new radio standardization. URLLC encompasses sporadic and
small-payload transmissions that should be delivered within extremely tight
radio latency and reliability bounds, i.e., a radio latency of 1 ms with
99.999% success probability. However, such URLLC targets are further
challenging in the 5G dynamic time division duplexing (TDD) systems, due to the
switching between the uplink and downlink transmission opportunities and the
additional inter-cell cross-link interference (CLI). This paper presents a
system level analysis of the URLLC outage performance within the 5G new radio
flexible TDD systems. Specifically, we study the feasibility of the URLLC
outage targets compared to the case with the 5G frequency division duplexing
(FDD), and with numerous 5G design variants. The presented results therefore
offer valuable observations on the URLLC outage performance in such
deployments, and hence, introducing the state-of-the-art flexible-FDD
technology.
