1. A data transmitting method in a UWB (ultra wide band) communication system, the method comprising:

  • transmitting predetermined sample data to sub-bands of each of a plurality of band groups;

    allocating transmission sub-bands according to performance rank information of the sub bands, the performance rank information determined based on applying weights to a loss of transmission power levels and error rates of the predetermined sample data for each of the sub bands;

    adjusting the transmission power levels of the allocated sub-bands within an allowable threshold value; and

    communicating according to the allocated sub-bands and the adjusted transmission power levels of the sub-bands wherein the adjusting of the transmission power level comprises;

    if the error rate of the predetermined sample data is smaller than the allowable threshold value, adjusting the current power level of the sub-band to the reduced power level; and

    if the error rate of the predetermined sample data is larger than the allowable threshold value, adjusting the power level of the sub-band to a previous power level.
