Toward 3GPP Sidelink-Based Millimeter Wave Wireless Personal Area Network for Out-of-Coverage Scenarios

Abstract

<p>With advancements in distributed autonomous systems (e.g., vehicles, sensors, and robots) in the 5G/6G era, sidelink communication technology has evolved as a distributed communication system in the third generation partnership project (3GPP). However, the current low-rate point-to-point sidelink communication design is not suitable for rapid development of such autonomous systems. Instead, based on sidelink, developing distributed wireless personal area networks (WPANs) with a drastically higher rate are essential. The overarching goal of this study is to explore the possibility of sidelink communication evolution to 1) form a distributed and autonomous WPAN and 2) support millimeter wave (mmWave) bands. Our core idea is to merge several design concepts of the precedented mmWave WPAN standards, i.e., IEEE 802.15.3c/11ad, into the sidelink communications, thereby bridging the gap between the two separated systems. This paper presents the anatomy of the IEEE 802.15.3c/11ad system with a focus on the formation of mmWave WPANs among distributed nodes and their operation. In addition, the current status of sidelink communication system design is highlighted, along with the missing building blocks, which are required to develop 3GPP sidelink-based mmWave WPAN systems. Simulation results on network formation signaling in the mmWave WPANs shed light on merging IEEE 802.15.3c/11ad concepts into 3GPP sidelink communication.</p> <p><br></p> <p><strong>This work has been submitted to the IEEE for possible publication.

Performance Evaluation of Low Sub-THz 5G NR Sidelink for Ultra-Wideband Short-Range Communication

“…However, in the low sub-THz band, a little longer distance can also be targeted as in the standardized 60 GHz WPAN system [5]. Hence, the use cases are summarized as an indoor point-to-point communication between two communicating nodes performing video streaming and a high-speed indoor WPAN among two or more nodes exchanging large sensory data among the nodes [5,12]. The communication range can be achieved to be several meters, which is demonstrated in this study in Section III.…”
