Abstract

In some cases, V2X systems may send warning messages. The warning messages may be sent over short distances. The warning messages may be useful over wider distances. Some systems may us MBMS from a V2X proximity broadcast. Electronic communications devices, such as UEs may be unaware of the MBMS. A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus may be an RSU. The RSU receive a V2X message from a UE. The RSU may broadcast information associated with the V2X message. The RSU may send the information associated with the V2X message to a network entity for a point-to-multipoint broadcast. The method, an apparatus, and a computer program product for wireless communication may also use V2X messages that include bootstrapping information to tune to an MBMS broadcast.

First claim

What is claimed is:

1 . A method of a roadside unit (RSU), comprising:
receiving a vehicle-to-X (V2X) message from a user equipment (UE); broadcasting information associated with the V2X message; and sending the information associated with the V2X message to a network entity for a point-to-multipoint broadcast.

2 . The method of claim 1 , further comprising:
receiving a point-to-multipoint broadcast including the information associated with the V2X message; and broadcasting the information associated with the V2X message received in the point-to-multipoint broadcast.

3 . The method of claim 2 , wherein the point-to-multipoint broadcast is a multimedia broadcast multicast service (MBMS) broadcast.

4 . The method of claim 2 , wherein the point-to-multipoint broadcast is a single cell point-to-multipoint (SC-PTM) broadcast.

5 . The method of claim 1 , wherein the V2X message includes bootstrapping information to tune to an MBMS broadcast.

6 . A method of a roadside unit (RSU), comprising:
receiving a point-to-multipoint broadcast including information from a first vehicle-to-X (V2X) message; and broadcasting the information associated with the first V2X message received in the point-to-multipoint broadcast.

7 . The method of claim 6 , wherein the point-to-multipoint broadcast comprises a multimedia broadcast multicast service (MBMS) broadcast.

8 . The method of claim 6 , wherein the point-to-multipoint broadcast comprises a single cell point-to-multipoint (SC-PTM) broadcast.

9 . The method of claim 6 , further comprising:
receiving a second V2X message, the second V2X message received from a user equipment (UE) and occurring before the point-to-multipoint broadcast and the first V2X message; and sending information associated with the second V2X message to a network entity, wherein the received second V2X message is associated with the first V2X message.

10 . The method of claim 9 , further comprising:
broadcasting information associated with the second V2X message; and refraining from broadcasting the information associated with the second V2X message upon broadcasting the information associated with the first V2X message.

11 . The method of claim 9 , wherein the information associated with the second V2X message is sent to the network entity over a backhaul.

12 . The method of claim 9 , wherein the first V2X message and the second V2X messages include incident information.

13 . The method of claim 9 , wherein the first V2X message and the second V2X message are identical.

14 . The method of claim 9 , wherein the first V2X message includes the second V2X message and information associated with a third V2X message.

15 . The method of claim 6 , wherein the V2X message includes bootstrapping information to tune to an MBMS broadcast.

16 . An apparatus for wireless communication, the apparatus being a roadside unit (RSU), comprising:
a memory; and at least one processor coupled to the memory and configured to: receive a vehicle-to-X (V2X) message from a user equipment (UE); broadcast information associated with the V2X message; and send the information associated with the V2X message to a network entity for point-to-multipoint broadcast.

17 . The apparatus of claim 16 , wherein the at least one processor is further configured to:
receive a point-to-multipoint broadcast including the information associated with the V2X message; and broadcast the information associated with the V2X message received in the point-to-multipoint broadcast.

18 . The apparatus of claim 17 , wherein the point-to-multipoint broadcast is a multimedia broadcast multicast service (MBMS) broadcast.

19 . The apparatus of claim 17 , wherein the point-to-multipoint broadcast is a single cell point-to-multipoint (SC-PTM) broadcast.

20 . The apparatus of claim 16 , wherein the V2X message includes bootstrapping information to tune to an MBMS broadcast.

21 . An apparatus for wireless communication, the apparatus being a roadside unit (RSU), comprising:
a memory; and at least one processor coupled to the memory and configured to: receive a point-to-multipoint broadcast including information from a first vehicle-to-X (V2X) message; and broadcast the information associated with the first V2X message received in the point-to-multipoint broadcast.

22 . The apparatus of claim 21 , wherein the point-to-multipoint broadcast comprises a multimedia broadcast multicast service (MBMS) broadcast.

23 . The apparatus of claim 21 , wherein the point-to-multipoint broadcast comprises a single cell point-to-multipoint (SC-PTM) broadcast.

24 . The apparatus of claim 21 , wherein the at least one processor is further configured to:
receive a second V2X message, the second V2X message received from a user equipment (UE) and occurring before the point-to-multipoint broadcast and the first V2X message; and send information associated with the second V2X message to a network entity, wherein the received second V2X message is associated with the first V2X message.

25 . The apparatus of claim 24 , wherein the at least one processor is further configured to:
broadcast information associated with the second V2X message; and refrain from broadcasting the information associated with the second V2X message upon broadcasting the information associated with the first V2X message.

26 . The apparatus of claim 24 , wherein the at least one processor is further configured to send the information associated with the second V2X message to the network entity over a backhaul.

27 . The apparatus of claim 24 , wherein the first V2X message and the second V2X messages include incident information.

28 . The apparatus of claim 24 , wherein the first V2X message and the second V2X message are identical.

29 . The apparatus of claim 24 , wherein the first V2X message includes the second V2X message and information associated with a third V2X message.

30 . The apparatus of claim 21 , wherein the V2X message includes bootstrapping information to tune to an MBMS broadcast.
