  • Publication number: 20070086474
    Abstract: A method is provided for estimating the size of a MAP region according to data burst allocation in a wireless mobile communication system. A data burst region is divided into at least one sub-region. A downlink frame is constructed with at least one sub-region such that a power boosting process is performed according to a predefined power level. The data burst is allocated to a specific sub-region of the sub-region according to a carrier to interference and noise ratio (CINR) of the data burst. A slot occupancy rate of data bursts allocated to the specific sub-region is computed. A concatenation or non-concatenation of the data bursts is set according to a predetermined criterion when the slot occupancy rate is less than a predefined slot occupancy rate. A size of the MAP region to be occupied by allocation information of the data bursts to be concatenated or unconcatenated is set.

  • Publication number: 20070060145
    Abstract: Disclosed is a method for resource allocation for a data burst in a communication system having a frame which is divided according time and frequency and includes a data burst allocation region. The method includes constructing the frame to have a structure in which the data burst allocation region is divided into at least one sub-data burst region for power amplification at a preset power level; and allocating the data burst to the sub-data burst region according to a standard.
