Method for channel assignment in a mobile communication system with space division multiple access

Abstract

In a mobile communication system with space division multiple access, under channel re-use conditions, the channel to be assigned to a terminal is determined by evaluating a cost of the assignment of each channel already in use. This cost is a function of the mean time that elapses between two successive channel assignments to the terminal, and it allows identifying the channel that allows maximising that time. The evaluation is performed by using cost coefficients that take into account 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 sectors and by detecting the instants of collision between terminals.
