Patent ID: 8027392

Claim:
A method for transmitting information between at least two transceivers linked together by a communication channel, the information being carried by means of at least one carrying signal having an operating frequency, the method comprising: dynamically selecting the operating frequency among frequencies comprised within at least two non-adjacent frequency intervals, wherein the same transmission scheme is used for transmitting signals at operating frequencies selected from the frequency intervals, the method being intended to be used in a cellular telecommunication system including at least one radio base station and at least one mobile terminal, the method further including execution by the at least one mobile terminal, of reporting of conditions of the two frequency intervals by transmitting at least one report signal, wherein in a cellular telecommunication system including at least one radio base station and at least two mobile terminals, the method further comprising: channel monitoring to be carried out by the mobile terminals and in the course of which each mobile terminal analyzes if frequencies included in first and second frequency intervals are suitable for being selected as operating frequencies for communicating with its current active base station; channel condition reporting in the course of which each mobile terminal reports to the base station the findings of the channel monitoring it has performed; frequency allocating to be carried out by the radio base station, in the course of which one of the frequencies will be allocated to each mobile terminal for enabling said terminal to communicate with the radio base station; and operating frequency switching in the course of which the operating frequency is to be switched from a formerly selected frequency to a newly selected frequency, such a switching being performed gradually by simultaneously attenuating progressively the signal transmitted at the formerly selected frequency and amplifying progressively the signal transmitted at the newly selected frequency.
