A method, device and system for radio frequency detection are disclosed in the disclosure, and the method for radio frequency detection according to the disclosure realizes to flexibly open a zero-power transmitting window by using the capability of a scheduler unit for dynamically managing time-frequency resources to match requirements of a measurement window on a transmitting channel controlled by the scheduler unit. The characteristics of the detection device is that a scheduler unit and a measurement unit have a transmission channel for transmitting measurement window information and/or zero-power transmitting window information, and by means of a method for opening a zero-power transmitting window according to the disclosure, a radio frequency detection unit not only can realize power measurement and/or information demodulation of an existing radio channel signal on an adjacent channel of a local transmitting channel, but also can realize online measurement of an out-of-band leak power and/or a transmitting power of a local transmitter. By means of the method of the disclosure, the radio detection system according to the disclosure can self-adaptively determine the width of a guard frequency band between its work channel and an adjacent channel performing transmission by using a different station address. |
