METHOD FOR CONTROLLING TRANSMISSION POWER OF SOUNDING REFERENCE SIGNAL IN WIRELESS COMMUNICATION SYSTEM AND APPARATUS FOR SAME
First Claim
1. A method for transmitting a sounding reference signal (SRS) by a terminal, the terminal receiving a downlink signal from a first base station and transmitting an uplink signal to a second base station in a wireless communication system, the method comprising:
- receiving downlink control information including a triggering message for a first SRS from the first base station;
determining transmission power of the first SRS based on the downlink control information; and
transmitting the first SRS to the first base station with the determined transmission power,wherein the downlink control information includes a transmission power control command field applied to a closed-loop parameter for the determination of the transmission power of the first SRS.

Abstract
In the present invention, disclosed is a method for a terminal, which receives a downlink signal from a first base station and transmits an uplink signal to a second base station, transmitting a sounding reference signal (SRS) in a wireless communication system. More specifically, the method comprises the steps of: receiving from the first base station downlink control information including a triggering message of a first SRS; determining transmission power of the first SRS on the basis of the downlink control information; and transmitting the first SRS to the first base station with the transmission power that is determined, wherein a transmission power control command field, which is included in the downlink control information, is applied to a closed loop parameter for determining the transmission power of the first SRS.
