Patent ID: 8111624

Claim:
Wireless telecommunication system including a transmitter and a receiver, the transmitter being used to transmit data packets to a receiver, the receiver including error detection means in order to detect if a received packet contains errors, wherein the receiver further includes means of outage detection in order to determine, in the event an error packet is detected, if the transmission channel between the transmitter and the receiver is in an outage situation and in order to transmit a first (OUTAGE) signal indicating this situation, the transmitter being used to modify the conditions of transmission in response to the first signal, the outage condition being established when the instantaneous mutual information is lower than the transmission bit rate, said transmission bit rate being calculated as R = k n ⁢ log ⁢ ⁢ Q where k and n are respectively the dimension and the length of the error-correcting code coding said data and Q is the degree of the symbol binary modulation used to transmit said data.
