Abstract:
1. A method of transmitting data, comprising the steps of: transmitting successively on a channel, from a first unit, data blocks destined for a second unit; for at least some of the transmitted data blocks, returning an acknowledgement signal from the second unit to the first unit, indicating whether said transmitted data block has been correctly received; transmitting on said channel, from the first unit, a redundancy block relating to at least some of the data blocks previously transmitted for which a received acknowledgement signal indicates incorrect reception, whereby each transmitted block is accompanied by an identification signal indicating whether said block is a redundancy block; associating, in the first unit, each received acknowledgement signal with a block transmitted in a determined temporal relation with the reception of said acknowledgement signal; and in at least some of the cases of reception of an identification signal inconsistent with an acknowledgement signal previously returned, returning from the second unit to the first unit a restart command signal for restarting transmission of blocks.
