Abstract
This application discloses a power control method and device of a Physical Uplink Control Channel (PUCCH) in a long term evolution (LTE) advanced system, relates to the technical field of wireless communications and is intended to reasonably determine the signal transmit power of a user equipment (UE) on the PUCCH to thereby improve the power utilization ratio of the user equipment. In this application, upon determining to bundle generated positive acknowledge (ACK)/negative acknowledge (NACK) information, the UE bundles the ACK/NACK information in a predefined bundling scheme, determines the power offset value corresponding to the number of bits carried on the PUCCH according to the bundling scheme and further determines the transmit power of the PUCCH. With the invention, the transmit power of the UE can be determined more reasonably.
