Claim of US Patent No. 10,694,528

1. A method for analyzing, using an access network of a wireless communication system, frequency resources within a predetermined multiplexing band, the wireless communication system comprising at least one terminal configured to select on its own a transmission frequency, within the predetermined multiplexing band, over which to transmit an uplink message to the access network, the method comprising:estimating, for at least one base station of the access network, capabilities for detecting uplink messages in different frequency sub-bands, respectively, within the predetermined multiplexing band;
assessing, for each frequency sub-band, a predetermined quality-of-service criterion as a function of a detection capability estimated for said each frequency sub-band;
transmitting to said at least one terminal, using the access network, a quality-of-service spectral map for said at least one base station, representative of frequency sub-bands for which the quality-of-service criterion has been verified and of frequency sub-bands for which said quality-of-service criterion has not been verified, wherein the terminal can select on its own a transmission frequency based on said quality-of-service spectral map.
