Radio equipment for a wireless communication system that transmits and receives signals in opposition, and a method for avoiding interference between radio equipment.

Abstract

The present invention aims to provide a technology for wireless devices used in wireless communication systems that transmit and receive signals from opposite sides, which makes the most effective use of frequency resources, minimizes dependence on the installation environment, and efficiently avoids interference. [Solution] The present invention provides a wireless device for use in a wireless communication system that performs transmission and reception between opposing devices, and is characterized by comprising: a receiving unit that receives transmission signals from opposing wireless devices and peripheral wireless devices within the wireless communication system; a synchronization unit that acquires the reception start timing; an interference detection unit that detects the interference intensity during reception; and an interference avoidance control unit that synchronizes the transmission and reception timing with peripheral wireless devices. Furthermore, the interference avoidance control unit is capable of changing the channel of the wireless device. It can also acquire identification information of the wireless device using a preamble signal or control signal included in the transmission signal and determine the peripheral wireless device with which to synchronize.
