Abstract
In a transmission method in a multiple access radiocommunication system with orthogonal transmission resources, to cater for a number of users greater than the number of transmission resources of the system, at least one of the transmission resources is shared at a given time by at least two users. The users sharing a transmission resource change with time so as to divide the deterioration of the signal to noise ratio resulting from such sharing as evenly as possible between the various users. The deterioration of the signal to noise ratio is further reduced by differentiating the signals corresponding to users sharing the same resource at a given time in terms of their transmit level.
