V2X Radio Interface
Kapitel i bok, 2021

This chapter provides insights into key aspects of the radio interface design for vehicle-to-everything (V2X) communications for connected automated driving and connected road user services. A key technology component in the 5G NR system is the application of beamforming techniques with narrow beams in the mm-wave spectrum to overcome the dominant path-loss effect. The chapter presents different beamforming schemes. It focuses on extensions of the air interface in the PHY and MAC layer to address the challenges for V2V communication among a large number of distributed vehicles in highly mobile environments. Short-range communication established by the V2V sidelink enables the facilitation of new communication concepts for V2X: neighboring user equipments in a close vicinity can cooperate in uplink and downlink transmissions with a base station to make use of additional link diversity, which can be beneficially exploited to improve overall reliability at a reasonable system cost.
