Abstract:
The present invention provides a method and user equipment for transmitting a physical uplink control channel. The method includes: in a carrier aggregation scenario, based on a predetermined rule, the transmission of the Physical Uplink Control Channel (PUCCH) is switched between a secondary component carrier and a primary component carrier, or the transmission of the PUCCH is only in the primary component carrier, which is selected by the user equipment (UE); and the UE transmitting the PUCCH in the selected component carrier. The present invention reduces the feedback time delay of uplink control information, and improves the utilization of uplink resources.
