Method of transmitting data in acknowledged mode between a sending unit and a receiving unit, and transmission unit implementing such a method
First Claim
1. Method of transmitting data in acknowledged mode between a sending unit and a receiving unit, in which the sending unit sends the receiving unit a sequence of blocks each comprising a header and data to be transmitted, and in which the header of each block comprises an acknowledgement control field activated intermittently by the sending unit so as to request an acknowledgement of blocks on the part of the receiving unit, the method comprising the following steps:
- /a/ the acknowledgement control field for some blocks of the sequence is activated in accordance with a predetermined triggering mode; and
/b/ 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 step /a/.

Abstract
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.

- 10. Unit for transmitting data in acknowledged mode, comprising means (45) for producing at least one sequence of blocks each comprising data to be transmitted and a header including an acknowledgement control field, means (42) for sending the blocks of the sequence to a receiving unit, and means (41) of intermittent activation of the acknowledgement control field in the header of the blocks of the sequence so as to request an acknowledgement of blocks on the part of the receiving unit, in which the means of intermittent activation comprise first means (44, 48) for activating the acknowledgement control field for some blocks of the sequence in accordance with a predetermined triggering mode, and second means (43, 48) for repeating the activation of the acknowledgement control field for at least one block of the sequence that was sent after a block where the acknowledgement control field has been activated by the said first means (44, 48).
