Abstract

The mmWave radio frequency (RF) spectrum allocations provide a large bandwidth and an excellent dynamic spectrum sharing (DSS) opportunity for emerging 5G New-Radio unlicensed (NR-U) and Wireless Gigabit (WiGig) services. To support constructive DSS, we outline a new modeling and analytical method to jointly evaluate the effects of a multiple-beam directional listen-before-talk (MB-DLBT) protocol, inter-cell interferences (ICIs), and spectrum sensing errors on the NR-U and WiGig DSS system performance. Available works did not provide a systematic and analytical approach to evaluate these effects, but only relied on computer simulations. Our numerical evaluation provides an insightful observation on the performance advantage of the MB-DLBT over the single-beam DLBT and omni-directional LBT schemes. This result provides a powerful tool to support performance analysis and optimization of mmWave DSS schemes.
