Embodiment Construction
[0037] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and the simulation of the embodiments.
[0038] Referring to Fig. 1, introduce the present invention to be used in OFDMA system five operation steps or the stage of the scheduling method that guarantees non-real-time service data packet time delay stability:
[0039] (1) The preparatory stage of resource division and parameter initialization: divide frequency domain and time domain resources, and the minimum unit of resource scheduling, determine the scheduling period, and establish the basic principles of power resource allocation and the implementation of the adaptive modulation and coding scheme adopted;
[0040] The specific content is to divide several subcarriers adjacent to the OFDMA system into a subband, and set N OFDM symbols whose number is a natural numbe...
