METHOD FOR CHANNEL ASSIGNMENT IN A MOBILE COMMUNICATION SYSTEM WITH SPACE DIVISION MULTIPLE ACCESS

摘要

In a mobile communication system with space division multiple access, under channel re-use conditions, the channel to be assigned to a terminal is deter mined by evaluating a cost of the assignment of each channel already in use. This cos t is a function of the mean time that elapses between two successive channel assign ments to the terminal, and it allows identifying the channel that allows maximisin g that time. The evaluation is performed by using cost coefficients that take into accoun t information on the topology of the cell and on the mobility of the terminals and are determined in a system initialisation phase by subdividing the cell into sec tors and by detecting the instants of collision between terminals.
