Abstract
Provided are an uplink power control method, user equipment and a base station. The method includes: receiving from a base station configuration information about a channel state information reference signal (CSI-RS), wherein the configuration information about the CSI-RS includes reference signal port information and reference signal power information; and measuring the path loss used for uplink power control based on the configuration information about the CSI-RS. The embodiments of the present invention take advantage of the CSI-RS to measure the path loss, which differs from a common CRS in that the CSI-RS can aim at a specific base station. Therefore, path loss measurement can be performed in respect of a target base station of uplink transmission, enabling the path loss compensation to match the actual path loss, thus improving the performance of uplink power control.
