Frequency hopping communication method for short-distance wireless communication, and related device

A method, comprising:

• receiving frequency hopping switching signaling from a primary device, wherein the frequency hopping switching signaling indicates a first frequency hopping sequence and a time point of frequency hopping switching, wherein the first frequency hopping sequence is different from a second frequency hopping sequence for frequency hopping communication, wherein the first frequency hopping sequence comprises N first channels, wherein the second frequency hopping sequence comprises N second channels, wherein M first reserved channels in the N first channels are consistent with M second reserved channels in the N second channels such that a location of the M first reserved channels and the M second reserved channels are the same, and an identifier of the M first reserved channels and the M second reserved channels are the same, wherein M and N are positive integers, and wherein M is less than N;
• and
• performing frequency hopping communication with the primary device using the first frequency hopping sequence at the time point of the frequency hopping switching.

A primary device, comprising:

• a transceiver, configured to send frequency hopping switching signaling to a secondary device, wherein the frequency hopping switching signaling indicates a first frequency hopping sequence and a time point of frequency hopping switching, wherein the first frequency hopping sequence is different from a second frequency hopping sequence for frequency hopping communication, wherein the first frequency hopping sequence comprises N first channels, wherein the second frequency hopping sequence comprises N second channels, wherein M first reserved channels in the N first channels are consistent with M second reserved channels in the N second channels such that a location of the M first reserved channels and the M second reserved channels are the same, and an identifier of the M first reserved channels and the M second reserved channels are the same, wherein M and N are positive integers, and wherein M is less than N;
• and
• a processor coupled to the transceiver and configured to perform frequency hopping communication with the secondary device using the first frequency hopping sequence at the time point of the frequency hopping switching.
