Embodiment Construction
[0016] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0017] figure 1 A flowchart showing a frequency reuse method for a WiMAX system according to an embodiment of the present invention, including:
[0018] Step S10, dividing the downlink frame of the base station into an outer ring area and an inner ring area, the inner ring area carries management control messages or user data for inner ring users, and the outer ring area carries management control messages or user data for outer ring users User data, and broadcast messages for outer ring users and inner ring users;
[0019] In step S20, the outer ring area adopts different OFDM subcarrier sets for different sectors of the base station.
[0020] The frequency reuse method allocates different OFDM s...
