SIST EN 303 798 V2.1.1:2024
(Main)Intelligent Transport Systems (ITS) - LTE-V2X and NR-V2X Access layer specification for Intelligent Transport Systems operating in the 5 GHz frequency band - Release 2
Intelligent Transport Systems (ITS) - LTE-V2X and NR-V2X Access layer specification for Intelligent Transport Systems operating in the 5 GHz frequency band - Release 2
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 [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 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 [i.1], 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.
Inteligentni transportni sistemi (ITS) - Specifikaciji LTE-V2X in NR-V2X dostopovne plasti pri inteligentnih transportnih sistemih, ki delujejo v frekvenčnem pasu 5 GHz, 2. izdaja
Ta dokument določa fizično plast, plast podatkovnih povezav in konfiguracijo radijskih virov, ki so združene v dostopovno plast referenčne arhitekture postaje ITS (ETSI TS 103 898 [i.2]). Tehnologija dostopovne plasti, določena v tem dokumentu, se navezuje na tako imenovano stransko povezavo oziroma vmesnik PC5 mobilne tehnologije V2X za naslednje frekvenčne pasove:
• delovanje v frekvenčnem pasu, namenjenem za ITS, za načine uporabe, povezane z varnostjo, v frekvenčnem območju od 5875 GHz do 5925 GHz;
• delovanje v frekvenčnih pasovih, namenjenih za ITS, za načine uporabe, ki niso povezani z varnostjo, v frekvenčnem območju od 5855 GHz do 5875 GHz.
Ta dokument je revizija standarda ETSI EN 303 613 [i.1] in razširja specifikacijo LTE-V2X dostopovne plasti tako, da vključuje NR-V2X.
Uporaba specifikacije LTE-V2X oziroma NR-V2X za prenos sporočil v kanalu ITS je določena s konfiguracijo na ravni sistema in ne spada na področje uporabe tega dokumenta.
