A method for activating multi-flow transmission user equipment (UE) to transmit a high speed (HS)- dedicated physical control channel (DPCCH) and the UE. The method is applied to a multi-flow transmission system. The method includes that the UE for activating multi-flow transmission transmits the HS- DPCCH bearing the joint coded acknowledgment character (ACK) / non-acknowledgment character (NACK) and a channel quality indicator (CQI) after set time with an HS-PDSCH subframe received later in a pair of HS-PDSCH subframes which are paired after the UE receives a high speed physical downlink shared channel (HS- PDSCH) subframe transmitted by a main service cell and an auxiliary service cell. The preset time is determined by the timing relation between the HS-DPCCH transmitted by the UE and the corresponding HS-PDSCH receiving subframe and regulated in third generation partner plan (3GPP) 25.211 protocol. The existing protocol is reused by means of the method and the UE.
