Abstract:
1. A method, of transmitting data packets over a transmission channel shared by a plurality of users, the method comprising steps of: generating at least two replicas of each packet to be transmitted; and sending said replicas over said transmission channel, separated by random time and/or frequency shifts, wherein said step of sending data packets is effected with a particular period specific to each user and further comprising a step of modifying said transmission period as a function of a loading state of the shared transmission channel, the method further comprising a step of inserting signaling information into each replica for enabling the other replica(s) of the same packet to be located in the time and/or frequency domain, and wherein said step of modifying the transmission period comprises: increasing said transmission period with a first probability if said loading state of the shared transmission channel exceeds a threshold value; and reducing said transmission period with a second probability if said loading state of the shared transmission channel falls below said value.
