Title: METHOD AND DEVICE FOR TRANSMITTING DATA
Abstract:
Disclosed are a method and device for transmitting data. The method comprises: a receiving end receives, by means of a secondary radio, a feature narrowband signal sent by a sending end; the receiving end turns on a primary radio according to the feature narrowband signal, a receiving bandwidth of the secondary radio being less than a receiving bandwidth and a sending bandwidth of the primary radio; the receiving end sends a first broadband signal to the sending end by means of the primary radio, the first broadband signal being used for indicating to the sending end that the receiving end has turned on the primary radio. According to the method for transmitting data, the sending end can determine, according to feedback of the receiving end (e.g., the first broadband signal), that the receiving end has turned on the primary radio. In this way, the sending end can send data to the receiving end after the receiving end turns on the primary radio, thereby improving the reliability of downlink transmission of the sending end.
