Method and apparatus for transmitting m2m ranging information in a wireless communication system

A method for receiving Machine to Machine (M2M) ranging information at an M2M device in a wireless communication system, the method comprising:

• acquiring synchronization to a Base Station (BS);
• and
• receiving an M2M ranging allocation UL MAP extended Information Element (IE) including M2M ranging region information,
• wherein the M2M device receives an UL MAP IE identifying the same region as the M2M ranging allocation UL MAP extended IE and wherein an Uplink Interval Usage Code (UIUC) of the UL MAP IE is 12.

A Base Station (BS) for transmitting Machine to Machine (M2M) ranging information in a wireless communication system, the BS comprising:

• a Radio Frequency (RF) Unit;
• and
• a processor,
• wherein the processor controls transmission of an M2M ranging allocation UL MAP extended Information Element (IE) including M2M ranging region information through the RF unit and, when the M2M ranging allocation UL MAP extended IE is transmitted, controls transmission of an UL MAP IE identifying the same region as the M2M ranging allocation UL MAP extended IE through the RF unit, and an Uplink Interval Usage Code (UIUC) of the UL MAP IE is 12.
