FREQUENCY HOPPING CHANNEL SELECTION METHOD AND APPARATUS, COMMUNICATION METHOD AND APPARATUS, AND COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/103573
Kind Code:
A1
Abstract:
A frequency hopping channel selection method and apparatus, a communication method and apparatus, and a communication system. The frequency hopping channel selection method comprises: step 202, acquiring first parameter information of a plurality of first channel groups in a working frequency band range of a transmitting end, the transmitting power of channels in the same first channel group being within a same preset range; step 204, acquiring second parameter information of a plurality of second channel groups in a working frequency band range of a receiving end, the attenuation amounts of signal strength of channels in the same second channel group being within a same preset range; and step 206, selecting a target channel group according to the first parameter information and the second parameter information. A frequency hopping channel is limited to the target channel group, such that the signal fluctuation is reduced during subsequent communication interaction between the transmitting end and the receiving end, and the interaction accuracy is increased. Additionally, by selecting the target frequency hopping group before communication interaction, the time for frequency hopping channel selection in a communication interaction process is reduced, and the communication efficiency is improved.
