In industrial net- works, manufacturing processes require hard real-time communication where the latency is less than 1ms. Time-sensitive networking (TSN) technology over Ethernet already supports deterministic de- livery for real-time communication. However, TSN technologies over wireless networks are currently in their initial development stage. Therefore, this study presents an overview of TSN research trends in wireless communications. This paper focuses on 5G networks and IEEE 802.11. We summarize standardization trends for TSN in 5G networks and introduce the TSN technologies for 802.11-based WLAN. Then, we introduce the integration scenario of 5GS with WLAN. This study provides insights into wireless communication technologies for wireless TSN.

Sahr Archis Vijay Ghate Program Authorized to Offer Degree: Electrical Engineering University of Washington Abstract Spectrum Sharing in White Spaces Farzad Hessar Chair of the Supervisory Committee: Professor Sumit Roy Electrical Engineering Demand for wireless Internet traffic has been increasing exponentially over the last decade, due to widespread usage of smart-phones along with new multimedia applications. The need for higher wireless network throughput has been pushing engineers to expand network capacities in order to keep pace with growing user demands. The improvement has been multi-dimensional, including optimizations in MAC/Physical layer for boosting spectral efficiency, expanding network infrastructure with reduced cell sizes, and utilizing additional RF spectrum. Nevertheless, traffic demand has been increasing at a much faster pace than network throughput and our current networks will not be able to handle customer needs in near future. While assigning additional spectrum for cellular communication has been a major ele- ment of network capacity increase, the natural scarcity of RF spectrum limits the extend of this solution. On the other hand, researchers have shown that licensed spectrum that is owned and held by a primary user is heavily underutilized. Examples are TV channels in the VHF/UHF band as well as radar spectrum in the SHF band. Hence, a more efficient use of this spectrum is to permit unlicensed users to coexist with the primary owner, i.e.
