In sum, by means of technical scheme of the present invention, can dispose setting according to real network is to backward compatibility 16e system, in the backward compatibility situation and according to service needed, the distribution of 16m subframe and 16e subframe is set, on the basis of the requirement of satisfying the IMT-Advanced systematic function, satisfy the demand of original WiMAX terminal.When not considering backward compatibility, can different transfer point numbers and the ratio of ascending-descending subframes be set according to the service delay demand, further satisfy the requirement of IMT-Advanced systematic function.In addition, by the descending control position of 16m information is set, make the 16m terminal not comprising the 16m down control channel and can closing radio-frequency transmissions without the subframe position of this terminal related resource assignment, enter the microsleep sleep mode, terminal is further economized on electricity.So just can be so that broadband access WiMAX of future generation system on the basis of the terminal of the original legacy version WiMAX of backward compatibility system, satisfies the IMT-Advanced system to reducing the requirement of the performances such as time delay, terminal power saving.
The above is the preferred embodiments of the present invention only, is not limited to the present invention, and for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
