Wireless communication system and method for sharing sensing antenna, sensing receiver and data antenna, data transmitter-receiver

PURPOSE: A data transceiver, a data transceiving antenna, a sharing method between a sensing receiver and a sensing antenna, and a wireless communication system are provided to improve the use efficiency of the transceiver and the antenna through smooth sharing of each transceiver and antenna. CONSTITUTION: In case a current time section is a data transceiving section, a data transceiver transmits and receives data(410,420). In case the time section is a QP(Quiet Period), the data transceiver receives inband sensing data with a sensing receiver(430,440). In case the time section is not the QP, a data signal processor confirms a separate sensing schedule(450). In case there is the sensing schedule, the data transceiver receives sensing data(460).
