A medium access control-high speed (MAC-hs) comprises a hybrid automatic repeat request (H-ARQ) device configured to receive data blocks over a wideband-code division multiple access (W-CDMA) high speed-downlink shared channel (HS-DSCH). The H-ARQ device generates an acknowledgement (ACK) or negative acknowledgement (NACK) for each said data block received. Each received data block having a transmission sequence number. The H-ARQ device receives a new transmission instead of a pending retransmission at any time. At least one reordering device has an input configured to receive an output of the H-ARQ device and the at least one reordering device configured to reorder the received data blocks based on each received data block's transmission sequence number (TSN). Received data blocks are immediately forwarded for processing for higher layers when the received data blocks are received in sequence.
