1. An operation method of a mobile subscriber (MS) for data exchange between the MS and a base station (BS) in a multicarrier communication system including the MS, and the BS providing a service to the MS, the method comprising the steps of:

  • dividing a full frequency band of the communication system into a plurality of sub-carrier frequency bands, generating a plurality of segments having a frequency domain and a time domain occupied by a predetermined number of sub-frequency bands and a predetermined number of time intervals, and classifying a plurality of segment types according to each of the segments, for data transmission;

    measuring a channel state and extracting channel state information corresponding to the channel state;

    estimating a segment type using the extracted channel state information, and determining whether there is a need for a change in a segment type currently allocated to the MS;

    if there is a need for a change in the segment type, transmitting a segment type change request message to the BS; and

    upon receiving a segment type change grant message from the BS in response to the segment type change request message, receiving data in a segment type corresponding to the received segment type change grant message.
