Table 2
In the present embodiment, the Image transmission equipment using the signaling frequency point for using figure to pass in the corresponding frequency range of frequency point as
Specified frequency hopping frequency point, and when being in the signalling time slot, the Image transmission equipment selects that jump can be used from the specified frequency hopping frequency point
It is frequent, it is described to meet default signalling condition with the channel quality of frequency hopping frequency point；It is understood that the application is implemented
Example does not do any restrictions for the setting of the signalling condition, can be specifically arranged according to actual conditions, such as described
Corresponding channel remaining bandwidth resource can be more than preset threshold, such as 90% or 95% specified frequency hopping frequency by Image transmission equipment
Point conduct can use frequency hopping frequency point.
In one possible implementation, the Image transmission equipment can carry out channel inspection to all specified frequency hopping frequency points
Survey, channel quality met into the specified frequency hopping frequency point of default signalling condition as can use frequency hopping frequency point, with this information it is possible to determine can
Be more than or equal to 1 with the quantity of frequency hopping frequency point, however, it is determined that the quantity of available frequency hopping frequency point be 1, then transmitting terminal can be with
It jumps to the available frequency hopping frequency point and can be used frequency hopping frequency point and receiving end progress signalling and receiving end same based on this
Step jumps to the available frequency hopping frequency point and carries out signalling based on the available frequency hopping frequency point and the transmitting terminal；If it is determined that can
It is greater than 1 with the quantity of frequency hopping frequency point, then communication two party (transmitting terminal and receiving end) can be based on the signaling selection made an appointment
Rule selection can use frequency hopping frequency point, so that it is guaranteed that communication two party work guarantees the reliable transmission of signaling data under same frequency point
And stablize transmission；It is understood that the application does not do any restrictions for signaling selection rule, it can be according to practical feelings
Condition is specifically arranged, such as vertical sequential selection first available frequency hopping frequency can be divided according to available frequency hopping frequency point
Point perhaps selects the last one available frequency hopping frequency point or selects the available frequency hopping frequency point etc. on designated position；It can also foundation
The sequence of the channel width resource with frequency hopping frequency point from big to small selects the available frequency hopping frequency that channel width resource is optimal
Point etc..
In alternatively possible implementation, the Image transmission equipment can be based on frequency hopping path successively to the specified jump
Again and again the channel put is detected, and can use frequency hopping frequency point until obtaining；The frequency hopping path is true by pre-generated pseudo noise code
Fixed, specifically, the frequency hopping path is to be passed in the corresponding frequency range of frequency point to described with figure based on pre-generated pseudo noise code
All specified frequency hopping frequency points be ranked up after generate, it is to be understood that generation of the application for the pseudo noise code
