RESOURCES SCHEDULING METHOD FOR SPECTRUM SHARING SYSTEM AND BASE STATION

摘要

The present invention provides a new resources scheduling method for a spectrum sharing system and a base station. According to the present invention, each base station divides its subscriber stations into the subscriber stations of overlapping region and the subscriber stations of non-overlapping region according to geographical position or other recognition mechanism for interference source. Each coexistent system executes a rough-scheduling process for radio time-frequency resources of its main sub-frame according to the grouping situation of the subscriber stations so as to determine whether the corresponding radio resources are allocated to the group of subscriber stations of overlapping region or the group of subscriber stations of non-overlapping region. The main system transmits the rough-scheduling information of its main sub-frame to other auxiliary systems so that it can be used in the rough-scheduling process of the auxiliary systems. Finally, the main system and other auxiliary systems of the main sub-frame, according to the rough-scheduling information, respectively execute precise-scheduling program according to the preset interference-elimination strategy and allocate the relevant resources to the specific subscriber stations. The solution provided by the present invention could effectively avoid the mutual interference between the systems before the interference happens, and effectively reduce the resources consumed by the information transmission between the systems.
