Introduction
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].
Pedestrian is not defined in the present document.

1 Scope
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
(LTE-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.

3.1 Terms
For the purposes of the present document, the terms given in ETSI EN 302 665 [i.2] and the following apply:
channel busy ratio: portion of sub-channels in the resource pool whose S-RSSI measured by the ITS station exceed a
(pre-)configured threshold sensed over last 100 ms
NOTE: This definition is access layer dependant and is specified in ETSI TS 136 214 [9] and is different to the
definition in ETSI EN 302 571 (V2.1.1) [i.5].
channel occupancy ratio: fraction of the total number of sub-channels used by the ITS station for its transmissions out
of the total number of configured (granted) sub-channels over a measurement period of 1 000 ms

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].

Introduction
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].
Pedestrian is not defined in the present document.

1 Scope
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
(LTE-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.
