1. , a kind of method of disturbing based on the cochannel in the system of broadband wireless communication of frame that reduces, wherein said communication system comprises a plurality of base stations and a plurality of terminal station, each terminal station is relevant with at least one base station, and each base station has relevant sub-district, each sub-district comprises a plurality of relevant sectors, described communication system comprises up link and down link, and described up link comprises the uplink signal that is divided into a plurality of time framesDescribed method comprises the steps:

  • (a) in the sight line sector relevant with selected base station, definite one group of terminal station may disturbing selected base station to receive from the terminal station, work is carried out with the frequency identical with selected base station at least one terminal station in the group of wherein said terminal station, to carry out work with the essentially identical polarization in selected base station and/or to comprise antenna towards selected base station;

    (b) determine first subclass in the group of described terminal station, wherein said first subclass communicates with first group of relevant base station, described first group of relevant base station is roughly along such ray setting, be that described ray crosses selected base station basically, and with described sight line sector oblique and/or parallel with described sight line sector;

    (c) determine second subclass in the group of described terminal station, wherein said second subclass communicates with second group of relevant base station, and described second group of relevant base station comprises the one or more base stations that not have roughly along the ray setting of crossing selected base station;

    (d) be first group of time frame of described first group of base station assigns;

    (e) be second group of time frame of described second group of base station assigns;

    (f) during described first group of time frame, transmit up-link information from the terminal station relevant with described first group of base station;

    (g) during described second group of time frame, transmit up-link information from the terminal station relevant with described second group of base station.
