Patent ID: 8811324

Claim:
A power control method for a Physical Uplink Control Channel, comprising: when response information of multiple Physical Downlink Shared Channels (PDSCH) sent by a base station over multiple component carriers is sent on one Physical Uplink Control Channel (PUCCH), the base station indicating a unified transmitted power control command for the Physical Uplink Control Channel; or, the base station indicating multiple transmitted power control commands for the Physical Uplink Control Channel; wherein: the base station sends a power control adjustment state g(i) of the PUCCH on a subframe i; the power control adjustment state g(i) is an absolute value transmitted power control: g ⁡ ( i ) = ∑ m = 0 M - 1 ⁢ ⁢ δ PUCCH ⁡ ( i - k m ) or the power control adjustment state g(i) is an accumulated value power control: g ⁡ ( i ) = g ⁡ ( i - 1 ) + ∑ m = 0 M - 1 ⁢ ⁢ δ PUCCH ⁡ ( i - k m ) wherein, g(i−1) is the power control adjustment state of the PUCCH on a subframe i−1, M and k m are related to configurations of a system, and ∑ m = 0 M - 1 ⁢ ⁢ δ PUCCH ⁡ ( i - k m ) is a sum of the transmitted power control commands indicated by the base station on subframes i−k 0 , i−k 1 , . . . , i−k M−1 .
