module to generate an ir zone in the second super frame step 904 is executed to enable the generation module to generate the at least one second pilot structure in the ir zone of the second super frame the steps 902 904 may be considered as a step of enabling the generation module to select at least one second pilot structure of a second super frame according to the pilot structure information and the at least one first pilot structure of the first super frame to generate the second super frame with the at least one second pilot structure finally step 905 is executed to enable the transceiver to communicate with the ss by the second super frame with the at least one second pilot structure to avoid a transmission interference between the bs and the another bs in addition the at least one second pilot structure comprises a plurality of pilots each of which comprises mitigation information so that the ss may further overcome the transmission interference according to the mitigation information in addition to the steps shown in fig9 this embodiment can also execute all the operations and functions of the third embodiment those of ordinary skill in the art will readily know how to execute the corresponding operations and functions in this embodiment by considering those in the third embodiment therefore a detailed description will be omitted here the method described above may be embodied in a computer readable medium storing the previously described computer program to execute the above steps the computer readable medium may be a soft disk a hard disk a compact disk a mobile disk a magnetic tape a database.
