Abstract

The present invention provides a power adjustment method and system, a base station, and user equipment, wherein the method includes: the UE receives downlink control information carrying a transmission power control TPC command word sent by the base station, and the UE according to the TPC command word and a first condition to determine a power control value corresponding to the power control command field, wherein the first condition is: the time information when the UE receives the downlink control information; or the physical downlink control channel PDCCH candidate position information or, non-TPC command word information in the downlink control information; or, a power control value preset in the UE, or, indication information sent by the base station for indicating a power control value. The above method can solve the problem in the prior art that the UE power is accumulated unnecessarily high or low due to PDCCH false alarm or false detection.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a power adjustment method and system, a base station, and user equipment. Background technique [0002] In 3GPP Long Term Evolution (abbreviation: LTE), the existing physical uplink shared channel (Physical Uplink Shared Channel; abbreviation: PUSCH) uplink power control algorithm adopts a combination of open-loop power control and closed-loop power control, wherein the power control According to whether the mobile station / terminal and the base station participate at the same time, it is divided into open-loop power control and closed-loop power control. Currently, the closed-loop power control is mostly used to compensate the error of the open-loop power control to achieve precise control of channel fading in a frequency division duplex (Frequency Division Duplexing, FDD for short) mode. [0003] For PUSCH transmission, considering the control signaling ...
