Abstract: The embodiments of the present invention disclose an uplink power control method, a terminal and a base station, which can adjust or determine uplink transmission power of a terminal on subframes which belong to different subframe groups respectively. The method includes: a base station determining subframe group information, the subframe group information being used by a terminal to determine uplink transmission power adjustment amounts on subframes which belong to different subframe groups; and the base station transmitting the subframe group information to the terminal. A terminal determines uplink transmission power adjustment amounts on subframes which belong to different subframe groups, and determines uplink transmission power on corresponding subframes according to the determined uplink transmission power adjustment amounts on the subframes which belong to the different subframe groups.

Abstract: Provided are methods and apparatuses for measuring CSI. The method comprises: a terminal device determining whether a subframe a channel state information interference measurement resource is located on is a downlink subframe; when the subframe where the channel state information interference measurement resource is located is a downlink subframe, the terminal device executing interference measurement by using the channel state information interference measurement resource. By means of the present disclosure, the technical problem is solved that it is difficult to effectively perform the CSI measurement caused when a base station flexibly adjust uplink-downlink configuration in a related technology, thereby achieving the technical effect of improving the data transmission performance of a system.
