METHOD AND APPARATUS FOR TRANSMITTING A SOUNDING REFERENCE SIGNAL IN A MULTI-COMPONENT CARRIER SYSTEM

WIPO Patent Application WO/2012/044023

A1

The present invention relates to a method for transmitting a sounding reference signal (SRS) in a multi-component carrier system, comprising the following steps: receiving an SRS set message for an uplink component carrier; starting an SRS transmission stop counting for the uplink component carrier on the basis of the SRS set message; and readjusting an SRS transmission period upon the completion of the SRS transmission stop counting. The method of the present invention controls an uplink reference signal transmission to prevent an unnecessary consumption of power in a terminal, and reduces unnecessary interference between said terminal and another terminal.
