The present document outlines the access layer of the Sidelink (PC5 interface) of Long Term Evolution based Vehicle

to Everything (LTE-V2X) communication technology ETSI TS 136 300 [2], which can be operated at the 5,9 GHz

frequency band allocated in Europe. LTE-V2X access layer consists of RRC layer, PDCP layer, RLC layer, MAC layer

and Physical layer. NAS layer is also introduced as part of access layer in the present document for the provision of

control. The LTE-V2X standard also adds features for congestion control to avoid unstable behaviour and for CEN

DSRC protection. The LTE-V2X standards are defined in ETSI TS 136 331 [1] and ETSI TS 136 414 [17].

The present document defines the physical layer and the data link layer and radio resource configuration, grouped into

the access layer of the ITS station reference architecture ETSI EN 302 665 [i.2]. The access layer technology that is

specified in the present document refers to what is known as the sidelink or PC5 interface of LTE Vehicle to everything
