Enhanced Distributed Resource Selection and Power Control for High Frequency NR V2X Sidelink Open
The 3GPP has standardized the 5G New Radio (NR) sidelink (SL) technology that enables direct device-to-device communications. SL will be key in realizing several high-speed, low-latency vehicle-to-everything (V2X) applications, such as aut…

Reducing the Paging Overhead in Highly Directional Systems Open
New Radio (NR) supports operations at high-frequency bands (e.g., millimeter-wave frequencies) by using narrow beam based directional transmissions to compensate high propagation losses at such frequencies. Due to the limited spatial cover…
