  • Patent number: 7587212
    Abstract: A method for determining a number of ranging slots by a base station (BS) in a broadband wireless access (BWA) communication system. The method includes counting the number of mobile stations (MSs) that succeeded in ranging in a current frame, determining a ranging slot occupation ratio in the current frame, comparing a ranging slot occupation ratio of a previous frame with the ranging slot occupation ratio of the current frame, detecting an increase in the number of ranging-requesting MSs, if the ranging slot occupation ratio of the current frame is greater than the ranging slot occupation ratio of the previous frame, and determining the number of ranging slots of a next frame such that the number of ranging slots of the next frame is greater than the number of ranging slots of the current frame.

  • Patent number: 7355960
    Abstract: A method and apparatus for defining at least one subcarrier as a subchannel, dividing a total frequency band into a plurality of subchannels, and allocating the subchannels to at least one mobile station in an OFDMA mobile communication system. The method includes receiving channel state information; comparing the received channel state information with a predetermined threshold, calculating an average occurrence length of a case in which the received channel state information is greater than the threshold, calculating a state hold prediction value, calculating an estimation value, sorting the calculated estimation values according to subchannels in order of their levels, and allocating subchannels according to the at least one mobile station in the sorted order.
