Methods and systems for updating group information

A method performed by a vehicle to everything (V2X) application enabler (VAE) server in a V2X communication system, the method comprising:

• receiving, from a first VAE client associated with a first V2X user equipment (LIE), a group information update request to update group information of a group associated with the first V2X UE and a second V2X UE;
• transmitting, to the second V2X UE, a group information update consent request based on identifying a capability associated with the second V2X UE;
• receiving, from the second V2X UE, a group information update consent response, the group information update consent response including information for informing whether the group information update consent request is accepted by the second V2X UE;
• and
• transmitting, to the first VAE client, a group information update response to inform a success or a failure for the group information update request.

• transmitting, to a second VAE client associated with a second V2X user equipment (UE), a group information update consent request for group information update of a group associated with the first V2X UE and a second V2X UE
• transmitting, to a first VAE client associated with a first V2X UE, an indication about the group information update;
• and
• receiving, from the second VAE client, a group information update consent response, the group information update consent response including information for informing whether the group information update consent request is accepted by the second V2X UE.

A vehicle to everything (V2X) application enabler (VAE) server in a V2X communication system, the VAE server comprising:

• a transceiver;
• and
• a controller coupled with the transceiver and configured to control to:
• receive, from a first VAE client associated with a first V2X user equipment (UE), a group information update request to update group information of a group associated with the first V2X UE and a second V2X UE;
• transmit, to the second V2X UE, a group information update consent request based on identifying a capability associated with the second V2X UE;
• receive, from the second V2X UE, a group information update consent response, the group information update consent response including information for informing whether the group information update consent request is accepted by the second V2X UE;
