Abstract

The invention relates to a process for controlling uplink transmission in a wireless communication network. It comprises broadcasting to the user equipments a maximum transmission rate, so as to limit the risks of collisions and the risk that the network collapses. In the case of a CDMA network, the maximum transmission rate may be broadcast as a maximum user bit rate, in the form of a minimum spreading factor. This information may be broadcast at each frame, so that it is taken into account by a user equipment for uplink transmission in the next frame. The invention also proposes processes for controlling access of the user equipment to the resources. These processes limit the number of users that may access the resources at a given time, or limit the throughput of the user equipment at the time the user equipment accesses the resource.
