The purpose of this TR is to document the identified LTE enhancements and corresponding evaluations
for LTE-based V2X services defined in TR 22.885
covering LTE-based communication between vehicles.
covering LTE-based communication between a vehicle and a device carried by an
individual (e.g. handheld terminal carried by a pedestrian, cyclist, driver or passenger).
covering LTE-based communication between a vehicle and a
roadside unit/network. A roadside unit (RSU) is a stationary infrastructure entity supporting V2X applications
that can exchange messages with other entities supporting V2X applications.
Note: RSU is a term frequently
used in existing ITS specifications, and the reason for introducing the term in the 3GPP specifications is to make
the documents easier to read for the ITS industry. RSU is a logical entity that combines V2X application logic
with the functionality of an eNB (referred to as eNB-type RSU) or UE (referred to as UE-type RSU).
This document addresses LTE-based V2X both with and without LTE network coverage, and covers both the operating
scenario where the carrier(s) is/are dedicated to LTE-based V2X services (subject to regional regulation and operator
policy including the possibility of being shared by multiple operators) and the operating scenario where the carrier(s)
is/are licensed spectrum and also used for normal LTE operation.
This technical report contains the evaluation methodology for LTE-based V2V, V2I/N and V2P services to compare the
performance of different technical options.
It identifies necessary enhancements to LTE for support of PC5 transport for V2V services.
It captures identification and evaluation of Uu transport for V2V and PC5/Uu transport for V2I/N and V2P
