SERVICE ZONE CHANGE ALGORITHM METHOD BASED ON LOAD CONSIDERING INTER-CELL INTERFERENCE IN 802.16/WIBRO SYSTEMS

摘要

PURPOSE: A service area change algorithm method based on load in 802.16/wibro system is provided to minimize interference between cells by supplying a service through FRF-1 area and FRF-3 area within a frame. CONSTITUTION: An area of one cell is divided in FRF-1 area and FRF-3 area in 802.16/wibro system(S100). One of FRF-1(Frequency Reuse Factor1) area and the FRF-3 area is selected within one frame based on traffic load and distribution of subscriber station(S200). A service is supplied through the selected the FRF-1 area and the FRF-3 area(S300). All the users within the cell use sub channels in the RFR-1 area. A cell area is divided in three sector units in the FRF-3 area. The cell area is classified into three sector units.
