Abstract
The present invention provides a data transmission method and apparatus in a time division duplex wireless data transmission system, and a system. The method includes: performing, by a transmission device in a timeslot corresponding to an idle frame, interference detection on a to-be-detected frequency band corresponding to the idle frame, obtaining an interference detection result, updating interference statistics, and switching, according to the interference statistics when interference to a current operating frequency band is greater than a preset threshold, the operating frequency band to a frequency band that meets a condition. Therefore, service interruption caused by interference detection is avoided.
