one or more indicators for V2X multicast service capabilities based on the V2X multicast bearer coverage for the wireless device, and
one or more configuration parameters for reception by the wireless device from the IMS network entity via a V2X multicast bearer;
sending, by the wireless device to the IMS network entity, a third message confirming establishment of the V2X multicast bearer coverage; and
receiving, via the V2X multicast bearer, at least one packet.
2 . The method of claim 1 , wherein the second message further comprises one or more configuration parameters for receiving via a V2X broadcast bearer.
3 . The method of claim 1 , wherein the first message further comprises a SIP header field indicating one or more target device types with which the wireless device supports V2X communications.
4 . The method of claim 3 , wherein the one or more target device types are associated with capability to communicate via at least one of:
vehicle to pedestrian communications;
vehicle to infrastructure communications;
vehicle to vehicle communications; or
vehicle to network communications.
5 . The method of claim 1 , wherein the one or more indicators for V2X multicast service capabilities comprise at least one of:
an IMS communication service identifier (ICSI); or
an IMS application reference identifier (IARI).
6 . The method of claim 1 , wherein the first message comprises at least one of:
an IMS communication service identifier (ICSI); or
an IMS application reference identifier (IARI).
7 . The method of claim 1 , wherein the first message further comprises a SIP header field indicating at least one of:
a PC5 communications V2X capability of the wireless device; or
an emergency communication capability of the wireless device.
8 . The method of claim 1 , further comprising receiving, by the wireless device from the IMS network entity, a response message comprising a SIP header field confirming registration of one or more target device types with which the wireless device supports V2X communications.
9 . A non-transitory computer-readable medium storing instructions that, when executed, cause:
sending, to an internet protocol multimedia subsystem (IMS) network entity, a first message comprising one or more indicators for vehicle-to-everything (V2X) multicast bearer coverage for a wireless device;
receiving, from the IMS network entity, a second message comprising:
one or more indicators for V2X multicast service capabilities based on the V2X multicast bearer coverage for the wireless device, and
one or more configuration parameters for reception by the wireless device from the IMS network entity via a V2X multicast bearer;
sending, to the IMS network entity, a third message confirming establishment of the V2X multicast bearer coverage; and
receiving, via the V2X multicast bearer, at least one packet.
10 . The non-transitory computer-readable medium of claim 9 , wherein the second message further comprises one or more configuration parameters for receiving via a V2X broadcast bearer.
11 . The non-transitory computer-readable medium of claim 9 , wherein the first message further comprises a SIP header field indicating one or more target device types with which a wireless device supports V2X communications.
12 . The non-transitory computer-readable medium of claim 11 , wherein the one or more target device types are associated with capability to communicate via at least one of:
vehicle to pedestrian communications;
vehicle to infrastructure communications;
vehicle to vehicle communications; or
vehicle to network communications.
13 . The non-transitory computer-readable medium of claim 9 , wherein the one or more indicators for V2X multicast service capabilities comprise at least one of:
an IMS communication service identifier (ICSI); or
an IMS application reference identifier (IARI).
14 . The non-transitory computer-readable medium of claim 9 , wherein the first message comprises at least one of:
an IMS communication service identifier (ICSI); or
an IMS application reference identifier (IARI).
15 . The non-transitory computer-readable medium of claim 9 , wherein the first message further comprises a SIP header field indicating at least one of:
a PC5 communications V2X capability of a wireless device; or
an emergency communication capability of the wireless device.
16 . The non-transitory computer-readable medium of claim 9 , further comprising receiving, from the IMS network entity, a response message comprising a SIP header field confirming registration of one or more target device types with which a wireless device supports V2X communications.
17 . A system comprising:
a wireless device; and
an internet protocol multimedia subsystem (IMS) network entity,
wherein the wireless device is configured to:
send, to the IMS network entity, a first message comprising one or more indicators for vehicle-to-everything (V2X) multicast bearer coverage for the wireless device;
receive, from the IMS network entity, a second message comprising:
one or more indicators for V2X multicast service capabilities based on the V2X multicast bearer coverage for the wireless device, and
one or more configuration parameters for reception by the wireless device from the IMS network entity via a V2X multicast bearer; and
send, to the IMS network entity, a third message confirming establishment of the V2X multicast bearer coverage, and
wherein the IMS network entity is configured to:
send, to the wireless device via the V2X multicast bearer, at least one packet.
18 . The system of claim 17 , wherein the second message further comprises one or more configuration parameters for receiving via a V2X broadcast bearer.
19 . The system of claim 17 , wherein the first message further comprises a SIP header field indicating one or more target device types with which the wireless device supports V2X communications.
20 . The system of claim 19 , wherein the one or more target device types are associated with capability to communicate via at least one of:
vehicle to pedestrian communications;
vehicle to infrastructure communications;
vehicle to vehicle communications; or
