The present document defines the physical layer, the data link layer and radio resource configuration, grouped into the access layer of the ITS station reference architecture ETSI TS 103 898. The access layer technology that is specified in the present document refers to what is known as the sidelink or PC5 interface of cellular V2X for the following frequency bands:
• Operation in frequency band dedicated to ITS for safety related applications in the frequency range 5,875 GHz to 5,925 GHz.
• Operation in frequency bands dedicated to ITS non-safety applications in the frequency range 5,855 GHz to 5,875 GHz.
The present document is a revision of ETSI EN 303 613, and extends the LTE-V2X access layer specification to include NR-V2X.
Whether LTE-V2X or NR-V2X is used for message transmission in an ITS channel is determined by a system level configuration and outside the scope of the present document.
