Method and apparatus for performing V2X communication on basis of cell group information

A method for performing vehicle-to-everything (V2X) communication by a multi-cell coordination entity (MCE) in a wireless communication system, the method comprising:

• receiving information on a cell group from a first base station (BS);
• transmitting the information on the cell group received from the first BS to a mobility management entity (MME);
• receiving an MBMS session update request message including the information on the cell group from the MME;
• and
• transmitting the MBMS session update request message including the information on the cell group received from the MME to one or more second BSs based on the information on the cell group received from the MME,
• wherein the information on the cell group is information related to a cell group to which a V2X message generated in a cell managed by the first BS is to be transferred, and
• wherein the second BS is a BS that manages a cell belonging to the cell group to which the V2X message generated in the cell managed by the first BS is to be transferred.

A multi-cell coordination entity (MCE) for performing vehicle-to-everything (V2X) communication, the MCE comprising:

• one or more memories storing instructions;
• one or more transceivers;
• and
• one or more processors connected to the one or more memories and the one or more transceivers, wherein the one or more processors execute the instructions to:
• receive information on a cell group from a first base station (BS);
• transmit the information on the cell group received from the first BS to a mobility management entity (MME);
• receive an MBMS session start request message including the information on the cell group from the MME;
• and
• transmit the MBMS session start request message including the information on the cell group received from the MME to one or more second BSs based on the information on the cell group received from the MME,
• wherein the information on the cell group is information related to a cell group to which a V2X message generated in a cell managed by the first BS is to be transferred, and
• wherein the second BS is a BS that manages a cell belonging to the cell group to which the V2X message generated in the cell managed by the first BS is to be transferred.
