Abstract: PURPOSE: A method for estimating a carrier to noise ratio in a wireless access system and a base station device thereof are provided to estimate information about a surrounding wireless environment in a wireless access system to which an SON(Self Organized Network) function is applied, thereby effectively performing self configuration. CONSTITUTION: A downlink signal is converted into a digital signal by an A/D converter(300). The digital signal is processed by FFT so that the digital signal is converted into a signal by a tone in the frequency domain. The signal converted into the frequency domain is converted into a frequency response about a preamble sequence by a multiplier(304). The mean value of instantaneous receiving power is calculated by an operation of an average calculating unit(310) by a block. A carrier power estimating unit(316) and a nose power estimating unit(314) estimate a carrier power estimation value and a noise power estimation value respectively.

Abstract: PURPOSE: A scheduling method in a multi-cell communications system is provided to schedule an external band and transmission power by considering a total system processing amount. CONSTITUTION: A scheduling device initializes scheduling related parameters and a priority coefficient(411). The scheduling device collects feedback information received from an eternal device(413).

Abstract: PURPOSE: A method and a device for transmitting and receiving resource allocation information are provided to reduce processing overhead by identifying values of pilot tones in the final sub channel in which the MAP message is allocated by an MS. CONSTITUTION: A discrambled signal is converted into a logic channel structure using a reverse sub-channelization pattern(804). An MS initializes a start point and a size of an individual MAP message(806). The MS determines whether the corresponding sub channel is the final sub channel of the individual MAP message(808). If the corresponding sub channel is not the final sub channel, the above process is performed again after increasing the size of the MAP message. If the corresponding sub channel is the final sub channel, the MCS level is initialized(812). The individual MAP message is demodulated by the reverse modulation, the deinterleaving, and decoding(816). If the CRC test is successful, the individual MAP message information is extracted(822).
