Content for TR 23.733 Word version: 15.1.0
1 Scope p. 8
The present document is the Technical Report for the study item "Study on architecture enhancements to ProSe UE-to-Network Relay". Its objective is to study and evaluate potential architecture enhancements needed to support the connection of an Evolved ProSe Remote UE with UICC with the network via an Evolved ProSe UE-to-Network Relay using E-UTRA (in coverage, in enhanced coverage or out of coverage) or Non-3GPP access technologies (enhancements to Non-3GPP access technologies are not part of this study).
2 References p. 8

3 Definitions, symbols and abbreviations p. 9
3.1 Definitions p. 9
For the purposes of the present document, the terms and definitions given in TR 21.905 and the following apply. A term defined in the present document takes precedence over the definition of the same term, if any, in TR 21.905.
eRelay-UE:
a Layer 2 relay in which a UE supports Indirect 3GPP Communication between an eRemote-UE and the 3GPP network, using E-UTRA, WLAN or Bluetooth between the eRemote-UE and the relay.
eRemote-UE:
a UE that is connected to a network using an Indirect 3GPP Communication.
Indirect 3GPP Communication:
The signalling and communication between a UE and 3GPP network, where there is an eRelay-UE between the eRemote-UE and the 3GPP network.
