| 摘要 |
The invention concerns a reception method for receiving sequences of sub-frames assigned to different users and transmitted by a transmitter over a plurality of channels (HS-SCCHs), each channel being shared among said users, said shared channels being time divided into intervals of transmission (TTIs), each sub-frame being transmitted in a TTI. When a sub-frame received by a user from a shared channel (HS-SCCH) is detected as erroneous, a negative acknowledgement (NACK) is sent back to the transmitter if the previous sub-frame on said shared channel was found not erroneous and no acknowledgement information is sent back to the transmitter if said previous sub-frame was detected as erroneous. <IMAGE>
