[R-5.1-001]
The message transmission shall be under control of the 3GPP network when the transmitting UE is served by the E-UTRAN.
[R-5.1-002]
A UE supporting V2X application shall be able to be pre-configured by the 3GPP network with parameters to be used for the transmission and reception of messages when not served by E-UTRAN supporting V2X communication.
[R-5.1-003]
A UE supporting V2X application shall be able to transmit and receive messages when served or not served by E-UTRAN supporting V2X communication.
[R-5.1-004]
An RSU shall be able to transmit/receive messages to/from a UE supporting V2X application.
[R-5.1-005]
The 3GPP system shall be able to support message transfer between UEs when served or not served by the same PLMN supporting V2X communications.
[R-5.1-006]
The 3GPP system shall be able to provide means to prioritize message transmission among UEs supporting V2X application
[R-5.1-007]
The 3GPP system shall be able to provide means to prioritize transmission of messages according to their type (e.g. safety vs. non-safety).
[R-5.1-008]
The 3GPP system shall be able to vary the transmission rate and range of the V2X communication based on service conditions (e.g., UE speed, UE density).
[R-5.1-009]
The 3GPP system shall be able to distribute information in a resource efficient way to large numbers of UEs supporting V2X application.
[R-5.1-010]
A UE supporting V2X application shall be able to identify whether E-UTRAN supports V2X communication.
[R-5.1-011]
The 3GPP system shall be able to provide means for an application server and the RSU to control the area and the size of the area where the messages are being distributed.
[R-5.1-011a]
The 3GPP system shall be able to provide means for distribution of messages from a UE supporting V2X application to locally relevant application servers.
[R-5.1-012]
The E-UTRA(N) shall be able to support a high density of UEs supporting V2X application.
[R-5.1-013]
Both the HPLMN and VPLMN operators shall be able to charge for network resource usage when messages are transferred by a UE supporting V2X application.
[R-5.1-014]
For UE supporting V2X application with limited resources (e.g., battery), the impact on its resources (e.g., battery consumption) due to message transfer should be minimized.
[R-5.1-015]
The 3GPP network should make available any supported positional accuracy improvement techniques (e.g., DGPS and/or OTDOA) in a resource efficient way to a subscribed UE supporting V2X application.
