3.1 Terms and definitions
The following terms and definitions as defined in GB/T 36628.1-2018 apply to this document.
3.1.1 Beacon
A pipe sent by the coordinator to keep synchronization with connected devices, describe the superframe structure, and deliver other LiPAN management information.
Information.
Note. Beacons can be divided into original beacons and additional beacons. The original beacon is a beacon periodically sent by the coordinator and transmitted in the beacon slot of each superframe. Attached
The beacon is a device-based request, and the beacon additionally sent outside the original beacon is generally sent in the GTS of the CFP area.
3.1.2 Compensation symbol
A pulse modulation symbol added for energy compensation during brightness adjustment.
3.2 Abbreviations
The following abbreviations apply to this document.
ACK confirmation (Acknowledgement)
AP access point (AccessPoint)
B2BIFS Beacon and Beacon Interval (BeaconToBeaconInter-FrameSpace)
