摘要：
A wireless access system supporting an M2M environment and, more particularly, a method and apparatus for multicasting a MAC control message respective to an M2M device is disclosed herein. According to an exemplary embodiment, a method for multicasting a MAC control message may include the steps of receiving a paging message including an MGID identifying an M2M group to which the corresponding M2M device belongs and an indicator indicating a multicast data transmission for the M2M device, receiving an M2M MA A-MAP IE including resource assignment information indicating a resource region to which the MAC control message respective to the corresponding M2M device is being transmitted, and, when a CRC bit being masked to the M2M MA A-MAP IE includes the MGID, receiving a MAC PDU being accompanied by the MAC control message being multicast through the resource region indicated by the resource assignment information.
