User Equipment-Side Initiation for 5G Communications
Abstract
The electromagnetic (EM) spectrum is an integral part of the modern battlefield, and the use of wireless connections presents both benefits and risks for U.S. forces. 5G New Radio (5G NR) represents the latest in wireless cellular technology and provides the foundation for a powerful network. However, the requirement for military communications to be lowprobability of detection (LPD) and low-probability of intercept (LPI) makes 5G NR unsuitable for use in hostile environments in its current form. 5G NR initial access procedures were designed to provide a large area of coverage to a high number of users and results insubstantial stray emissions. This research seeks to introduce a replacement procedure for 5G NR initial access utilizing a user equipment-side connection process (UECP). By capitalizing on the directionality of massive multiple-input multiple-output antenna arrays (MIMO) and utilizing a novel detection process known as passive array sweep listening (PASL), connections can be established between the user equipment(UE) and gNodeB (gNB) at ultra-low signal-to-noise ratios (SNRs). The performance of UECP was evaluated utilizing multiple simulations created in MATLAB. The ability of UECP to function at ultra-low SNRs, combined with the directionality of large antenna arrays, results in a substantial decrease of stray emissions normally found in 5G NR initial access, which greatly reduces the probability of intercept or detection.
