10. method according to claim 9, is characterized in that,
Before upstream time section in the current frame occurs described first trigger event, in the upstream time section of present frame, notify described second wireless terminal;
When described first trigger event occurs, in upstream time section in the current frame, to notify described second wireless terminal in the described upstream time section of the next frame of present frame.
11. methods according to claim 9, is characterized in that,
Arranging a predetermined number frame is one-period, and each cycle comprises 4 frames;
In first frame in described cycle, retain described downgoing time section and upstream time section, in all the other frames in described cycle, only retain described upstream time section;
Or, in first frame in described cycle, retain described downgoing time section and upstream time section, in all the other frames in described cycle, do not retain described downgoing time section and upstream time section.
12. methods according to claim 3, is characterized in that,
Described first wireless terminal adopts the first transmission mode to communicate with the second wireless terminal;
When described second wireless terminal detects one second trigger event, and when the 3rd transmission mode corresponding to described second trigger event is different from described first transmission mode;
The marker frames that the Base Band Unit of described second wireless terminal is determined loads a pattern switching command;
Described Real-time hardware layer data communication protocol is adopted by described marker frames to send to described first radio frequency unit by described second radio frequency unit,
Communicate with described 3rd transmission mode between second radio frequency unit with described first radio frequency unit.
