Stochastic Analysis on Downlink Performance of Coexistence between WiGig and NR-U in 60 GHz Band

Abstract

The 60 GHz band (57-71 GHz) has been attracting considerable research interest thanks to the bandwidth abundance and ruling as an unlicensed band. The 60 GHz Wi-Fi (also known as WiGig) and 5G New Radio Unlicensed (NR-U) are among the key access technologies that will operate in the band. This paper inspects the downlink performance of the two technologies under inter-technology interference from each other in 60 GHz band. Based on a dense small-cell setting, this paper finds stochastic models for signal-to-interference-plus-noise ratio (SINR) and data rate. Via simulations, this paper discovers that the downlink SINR and data rate follow Gaussian mixture distributions with three modes representing (i) severely interfered, (ii) mildly interfered, and (iii) not interfered UEs.

This paper will be submitted to IEEE VTC 2020 Fall
