Claim Text:
1. A method for transmitting a physical uplink control channel, comprising: in a carrier aggregation scenario, based on a predetermined rule, a User Equipment (UE) selecting to switch transmission of a Physical Uplink Control Channel (PUCCH) between a primary component carrier and a secondary component carrier, or only to transmit the PUCCH in the primary component carrier; and the UE transmitting the PUCCH in a selected component carrier; wherein the step of switch transmission of the PUCCH between the secondary component carrier and the primary component carrier comprises: when there is the PUCCH that needs to be transmitted in a subframe N, when there is no primary uplink component carrier while only a secondary uplink component carrier in the subframe N, the UE transmitting the PUCCH in the secondary uplink component carrier of the subframe N; or when there is the primary uplink component carrier in the subframe N, the UE transmitting the PUCCH in the primary uplink component carrier of the subframe N, wherein, N is a subframe number; or, when there is the primary uplink component carrier and the secondary uplink component carrier in the subframe N and both the primary uplink component carrier and the secondary uplink component carrier have a corresponding PUCCH which needs to be transmitted, the UE selecting to transmit the corresponding PUCCH on the primary uplink component carrier and the secondary uplink component carrier of the subframe N at the same time.
