APPARATUS FOR TRANSMITTING/RECEIVING MULTICAST DATA IN WIRELESS COMMUNICATION SYSTEM AND METHOD THEREOF
First Claim
1. A method of receiving multicast data by an M2M (machine-to-machine) device in a wireless communication system, the method comprising:
- receiving, information including an M2M group identifier (MGID) assigned to the M2M device, from a base station;
receiving, a message related to M2M multicast assignment including the MGID, from the base station; and
receiving the multicast data based on the message from the base station, wherein the multicast data comprises a flow identifier (FID) field in a MAC header of a MAC PDU (medium access control packet data unit) for a multicast service flow, andwherein the FID field is set to a specific value.

Abstract
An apparatus for transmitting/receiving multicast data in a wireless communication system and method thereof are disclosed. The present invention includes receiving information including an M2M group identifier (MGID) assigned to an M2M (machine-to-machine) device from a base station, receiving a message related to M2M multicast assignment having the MGID information applied thereto from the base station, and receiving the multicast data from the base station in accordance with instruction of the message from the base station, wherein the multicast data comprises a flow identifier (FID) field in a MAC header of a MAC PDU (medium access control packet data unit) for a multicast service flow and wherein the FID field is set to a specific value.
