Method of transmitting data in acknowledged mode between a sending unit and a receiving unit, and transmission unit implementing such a method

摘要

The sending unit (30) produces a sequence of blocks each comprising data to be transmitted and a header, that it sends to a receiving unit (31). The header of each block comprises an acknowledgement control field activated intermittently so as to request an acknowledgement of blocks on the part of the receiving unit. The acknowledgement control field for some blocks of the sequence is activated in accordance with a predetermined triggering mode, and the activation of the acknowledgement control field is repeated for at least one block of the sequence that was sent after a block where the acknowledgement control field has been activated in accordance with the predetermined triggering mode.
