Abstract
A method for allocating resources for a spread-spectrum communication system includes a plurality of communicating devices able to communicate with a server via at least one network access gateway, the method comprising the steps of: measuring a quality metric of the communication link for each communicating device over a given time window, determining at least one statistical indicator of the signal-to-interference ratio between each pair of communicating devices based on the quality metric, allocating each communicating device a spreading factor and at least one time slot to communicate, in accordance with a coexistence criterion dependent on the spreading factor and on the statistical indicator of the signal-to-interference ratio, the time resources being organized in the form of super-frames comprising first communication slots wherein several devices are able to communicate simultaneously using different spreading factors and second communication slots wherein several devices are able to communicate sequentially using the same spreading factor, the first communication slots being allocated to the devices that comply with the coexistence criterion, the second communication slots being allocated to the devices that do not comply with the coexistence criterion.
