Claim Text:
1. A method for a User Equipment (UE) which activates a multi-stream transmission to transmit a High Speed Dedicated Physical Control Channel (HS-DPCCH), applied in a multi-stream transmission system, comprising: the UE which activates a multi-stream transmission receiving High-Speed Physical Downlink Shared Channel (HS-PDSCH) subframes transmitted by a primary serving cell and HS-PDSCH subframes transmitted by a secondary serving cell, transmitting an HS-DPCCH carrying jointly encoded Acknowledge/Negative Acknowledgement (ACK/NACK) and Channel Quality Indicator (CQI) after a predetermined duration based on a later received HS-PDSCH subframe of a paired HS-PDSCH subframes which are paired with one of the HS-PDSCH subframes transmitted by the primary serving cell and one of the HS-PDSCH subframes transmitted by the secondary serving cell respectively, wherein the predetermined duration is determined according to a timing correlation by which the UE transmits an HS-DPCCH subframe and correspondingly receives an HS-PDSCH subframe, which is specified in the 3
