Abstract

Disclosed are a method and a device for power control information informing and power control, which relate to a wireless communication technology field and are used to solve the problem how to make a Sounding Reference Signal (SRS) sent by a terminal satisfy different measurement requirements. In this invention, after determining an SRS power control process used by a terminal, the base station informs the terminal of the SRS power control process used by the terminal, and the terminal determines the SRS uplink sending power based on an SRS power control parameter corresponding to the SRS power control process, and transmits the SRS according to the uplink sending power. With this scheme, the SRS sent by the terminal can satisfy different measurement requirements.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a power control information notification and power control method and device. Background technique [0002] In the existing Long Term Evolution-Advanced (LTE-A) system, the Sounding Reference Signal (Sounding Reference Signal, SRS) can be used to measure the quality of the uplink channel, thereby performing uplink scheduling, and can also use channel mutual The heterogeneity is used to obtain downlink channel information for downlink scheduling and transmission. In a Cooperative Multiple Point Transmission (CoMP) system, due to the independence of uplink and downlink transmission, the channel to be measured for uplink transmission and the channel information to be obtained for downlink transmission are often different, so sounding is required The set of transmission points measured is also different. For uplink transmission, usually the measurement points are relatively cl...
