Method and equipment for controlling protection device initialization

Abstract

The present invention discloses a method and a device of controlling protection equipments from initialization. The method of controlling protection equipments from initialization comprises the following procedures: receiving information frame that transmitted by high level of protection equipments; indicating whether the protection equipment in physical layer in initialization transmitting process according to the information frame. According to the invention, a method of controlling main protection equipment whether or not include communication period among equipments is designed so that the controlling information could be transmitted among high level of equipments, MAC sub-layer and physical layer. The structure of protocol stack is perfected. Primitive interoperation between MAC sub-layer and physical layer is reduced and efficiency of protocol stack is improved after appropriate primitive design.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a method and device for controlling the initialization of protection equipment. Background technique [0002] With the promotion of digital TV, the utilization rate of the frequency band originally used for analog TV is getting lower and lower. Currently license-exempt devices are permitted to use this unused TV band without causing interference. Although these TV channels are not used to broadcast TV signals, other low-power licensed devices, such as wireless microphones, also operate on these TV channels. Therefore, it is particularly important to protect these low-power devices from interference. [0003] The IEEE 802.22.1 standard defines a protective device (Protecting Device, PD) or beaconing device (Beaconing Device) to form a beacon network (Beaconing Network), to strengthen the authorization of low-power primary user equipment (such as wireless microphones) prot...

AI Technical Summary

Problems solved by technology

[0023] The disadvantage of the existing technology is that: the superframe structure sent during the initial transmission process of the master protection device does not include the inter-device communication period, so the physical layer of the master protection device must send a synchronization burst on the synchronization channel corresponding to the 31st time slot , and send 4 bytes of zero bits on the beacon channel

However, the physical layer of the main protection device does not know whether the device is in the initialization transmission process, and cannot judge whether to include the inter-device communication period.
