Abstract: A first rate matching stage matches a number of input bits coming from a transport channel including a high-speed downlink shared channel (HS-DSCH) of a block of data bits to be transmitted from a base station of a communications network to one or more pieces of user equipment (UE) to a selected number of intermediate bits as determined by the buffer size management system. A virtual buffer stores the selected number of intermediate bits. A second rate matching stage matches the selected number of intermediate bits to a number of output bits equal to a maximum number of bits that is guaranteed to be transmitted by a set of high-speed physical downlink shared channels (HS-PDSCH) associated with the transport channel in a given time interval without adding bits.

Abstract: A device (D) is dedicated to managing transmission of digital data blocks in High-Speed Downlink Shared Channel (HS-DSCH) downlink transport channel set up between a base station of a communications network and a user equipment. It comprises processing means (MT) adapted, each time that a given block must be transmitted to the user equipment via the transport channel, to select successive values of the redundancy parameter XRV in accordance with a selected sequence in which the value of the redundancy parameter XRV used for the first block transmission is selected to give priority to transmitting systematic bits.
