Patent ID: 8537749

Claim:
A method for transmitting data from a radio communication network infrastructure to user devices, said data being carried by a sequence of frames broadcast to the user devices, each frame comprising a first section comprising data and a second section comprising redundancy information associated with the data of a predetermined number B of previous frames in the sequence, which method comprises, relative to a user device: comparing a number of consecutive lost frames to a threshold dependent on the number B of previous frames with which said redundancy information is associated and on the coding rate of an encoding upon which generation of the redundancy information is based, wherein said threshold is chosen to be equal to: B × 1 - T T , where T refers to the coding rate of the encoding upon which the generation of said redundancy information is based; and, sending a request to retransmit at least one of the consecutive lost frames to the radio communication network infrastructure if the number of consecutive lost frames exceeds said threshold.
