Patent ID: 8315153

Claim:
A wireless communication equipment comprising receive processing and transmit processing, wherein the receive processing includes: a Fourier transform unit that transforms all received signals to frequency region signals by Fourier transform; a demodulation unit that demodulates the received signals from the Fourier-transformed frequency region signals; and a random access detection unit that monitors signals in frequency regions of random access signals of the Fourier-transformed frequency region signals, and detects that the random access signals are received, by a change pattern of the signals in the frequency regions of random access signals in one transmission time interval, wherein the Fourier transform unit is a Fourier transform unit for data signals, wherein the random access detection unit, for frequency region signals transformed from the received signals by the Fourier transform unit for data signals, monitors power in bands allocated to the random access signals, and detects whether the random access signals are received using a change pattern of the power in the one transmission time interval, wherein the received signals include data signals for transmitting information, and the random access signals transmitted by user equipments for sending a transmission request to a base station, and wherein the random access detection unit reflects the difference between the format of the random access signals and the format of the data signals on a change pattern of power, and detects the random access signals.
