1. complete a method for Resourse Distribute in ofdm transmission, comprise step:

  • -completing that OFDM frequency spectrum is divided into multiple predefined district for multiple OFDM transmission community (2.1-2.3), described multiple predefined district comprises multiple first kind subcarrier (SCi) district (Rij) and multiple Equations of The Second Kind subcarrier district (R '"'"' ij);

    And-to specify the first through-put power to described first kind subcarrier district and specify the second through-put power to described Equations of The Second Kind subcarrier district, wherein said first through-put power is higher than the second through-put power;

    It is characterized in that, comprise step further;

    -depend on described first and second through-put powers, distribute described resource to carry out the communication of given base station (3.1-3.3) and the first user equipment (4.1-4.4) associated at least one first kind subcarrier district, and at least one Equations of The Second Kind subcarrier district, carry out the communication of described given base station (3.1-3.3) and the second subscriber equipment associated, and-described division and described first and second through-put powers of specifying sent to base station in OFDM transmission system (1) (3,3.1-3.3), and send the subscriber equipment (4.1-4.4) be operationally connected with described base station to, and-change frequency planning, disturbed condition, flow condition, geographical position and channel quality are made and being reacted flexibly, first kind subcarrier district from the second community in the first kind subcarrier district of the first community borrows multiple subcarrier, wherein said first community is adjacent with described second community, and there is the demand to resource in its space outerpace district in described first community, and different with Equations of The Second Kind subcarrier district through-put power each other by first kind subcarrier district, obtain the orthogonality of interference coordination.
