Claim Text:
1. A method for receiving a Medium Access Control (MAC) control message for an M2M device in a wireless access system, the method comprising: receiving, by the M2M device, a broadcast assignment map information element (BA A-MAP IE) including a function index field and broadcast assignment information, wherein the function index field indicates that the BA A-MPA IE carries the broadcast assignment information for the M2M device and the broadcast assignment information indicates a resource region to which the MAC control message is being transmitted; and receiving, by the M2M device, the MAC control message through the resource region which is indicated by the broadcast assignment information, when a cyclic redundancy check (CRC) bit masked to the BA A-MAP IE indicates that the BA A-MAP IE is for a M2M broadcast assignment, wherein the CRC bit being masked to the BA A-MAP IE is configured to a 1-bit masking prefix, a 3-bit type indicator, and a 12-bit masking code, and wherein the masking code is used to mask the BA A-MAP IE for the M2M broadcast assignment.
