Abstract: Provided are a device and method in a radio communication system, and radio communication system. The device at a transmitting side comprises: a channel detection unit configured to detect whether a transmitting-end channel in an unlicensed frequency band is idle; and a coordination unit configured to enable, if the transmitting-end channel is idle, the transmitting side to broadcast an inter-operator coordination signal before transmitting a data stream, so as to realize information interaction between apparatuses of different operators, wherein the inter-operator coordination signal implements, by means of presence/absence of energy in a specified frequency band, an energy pattern signal on a time-frequency domain plane for the information interaction between the apparatuses of different operators. By enabling inter-operator information interaction in an unlicensed frequency band by means of an energy pattern signal, the embodiments of the present disclosure eliminate difficulties of reception and demodulation for signal detection between apparatuses of different operators, thus effectively realizing coordination between the apparatuses of different operators, and improving system performance.
