Abstract:
1. A device for managing transmission of digital data blocks of digital data in a High Speed Downlink Shared Channel (HS-DSCH) downlink transport channel set up between a base station of a communications network and a user equipment, said digital data being of a systematic type and parity 1 or parity 2 type, said device comprising: processing means for selecting a first value of a redundancy parameter in view of a first transmission of a first digital data block to said user equipment including a first set of digital data selected as a function of said first value, wherein, in the event of incorrect reception of the first digital data block by said user equipment, the processing means select at least a second value of said redundancy parameter in view of a second transmission to said user equipment of at least a second digital data block including a second set of digital data selected as a function of said second value, and wherein, each time that a given digital data block must be transmitted in said channel, the processing means select successive values of the redundancy parameter in accordance with a selected sequence in which the value of the redundancy parameter used for the first transmission is selected to give priority to transmitting systematic bits and values of the redundancy parameter in the selected sequence used for digital data block transmissions after the first transmission are selected to give priority alternately to transmitting parity 1 or parity 2 bits and to transmitting bits.
