Abstract
A power control method for a Physical Uplink Control Channel, which includes: when the 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. The present invention also provides a base station and a user equipment.
Claims21
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.
A base station, which is configured to:
- when response information of multiple Physical Downlink Shared Channels (PDSCH) sent over multiple component carriers is sent on one Physical Uplink Control Channel (PUCCH), indicate a unified transmitted power control command for the PUCCH;
- or indicate multiple transmitted power control commands for the PUCCH.
A user equipment, which is configured to:
- when a base station sends response information of multiple Physical Downlink Shared Channels (PDSCH) sent over multiple component carriers on one Physical Uplink Control Channel (PUCCH), receive a unified transmitted power control command or multiple transmitted power control commands indicated by the base station for the PUCCH, and determine a power control adjustment state g(i) of the PUCCH sent on a subframe i as an absolute value power control according to the transmitted power control command:
