The MAC frame in a wireless communication system includes a terminal ID allocated to each of multiple terminals. At least one connection ID is allocated to each terminal having the terminal ID, and sub-carrier allocation information is allocated to each connection having the connection ID. The sub-carrier allocation information includes a sub-carrier allocation status for each sub-carrier, and the number of allocated information bits for each sub-carrier. The sub-carrier allocation status and the number of allocated information bits for each sub-carrier can be allocated, by sub-carriers, to the sub-carrier allocation information using a same number of bits; or the information on the sub-carrier allocation status is first allocated to the sub-carrier allocation information and the number of allocated information bits for each sub-carrier is allocated.

What is claimed is: 1. A method of registering a terminal in an access point of a wireless communication system, the method comprising:receiving a first ranging request message from the terminal using an access interval of an uplink sub-frame of a frame of a plurality of frames, wherein the access interval is used to receive the first ranging request message from the terminal on a contention basis;sending a first ranging response message allocating a ranging slot to the terminal using a map message of a downlink sub-frame of a frame of the plurality of frames;receiving a second ranging request message from the terminal using the allocated ranging slot;sending a second ranging response message to the terminal in response to receiving the second ranging request message;after sending the second ranging response message, receiving a registration request message from the terminal using a second management connection interval of a frame of the plurality of frames; andsending information on whether to permit the registering to the terminal using a first management connection interval of a frame of the plurality of frames,wherein each frame of the plurality of frames comprises a downlink sub-frame and an uplink sub-frame, wherein the downlink sub-frame includes a broadcast interval and a first management connection interval, and the uplink sub-frame includes an access interval and a second management connection interval, the broadcast interval being used for transmitting a map message.
