Title:
FREQUENCY SWEEPING METHOD AND TERMINAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/047578
Kind Code:
A1
Abstract:
A frequency sweeping method and a terminal device, which are used to solve the technical problem in existing technology of an NB-IoT terminal having a long frequency sweeping time. The frequency sweeping method comprises: determining a first frequency point set (FreqPointSet) on the basis of a bandwidth to be swept, the first FreqPointSet comprising NFreq frequency points, NFreq being an integer greater than or equal to 1 (S101); sweeping the first FreqPointSet by using a first frequency sweeping mode, the first frequency sweeping mode being used to determine a frequency point in which a cell whose signal to noise ratio SNR is greater than a first SNR threshold is located (S102); if a target cell is not detected at any frequency point of the first FreqPointSet, sweeping a second FreqPointSet in the first FreqPointSet by using a second frequency sweeping mode, the second frequency sweeping mode being used to determine a frequency point in which a cell whose SNR is greater than a second SNR threshold is located, the first SNR threshold being greater than the second SNR threshold, the second FreqPointSet comprising MFreq frequency points, and MFreq being a positive integer less than or equal to NFreq (S103).
