Abstract

The present invention relates to a method in which a terminal transmits a sounding reference signal in a wireless communication system. Specifically, the method includes: receiving sounding reference signal setting information from a base station; and transmitting the sound reference signal to the base station on the basis of the sounding reference signal setting information, wherein an upstream link signal based on the sounding reference signal is transmitted over an upstream link control channel, and a frequency band corresponding to an upstream link data channel and a frequency band corresponding to an upstream link control channel are allocated as frequency resources for the sounding reference signal.

Claims

1. A method for transmitting sounding reference signals via a plurality of antennas from a user equipment in a wireless communication system, the method comprising:

receiving information for triggering an additional sounding reference signal from a base station; and

transmitting a periodical sounding reference signal and the additional sounding reference signal via the plurality of antennas to the base station in a subframe including first and second slots, each of the first and second slots including a plurality of symbols,

wherein one symbol is reserved for a DM-RS (DeModulation-Reference Signal) in each of the first and second slots,

wherein the periodical sounding reference signal is transmitted on a last symbol in the second slot of the subframe, and

wherein the additional sounding reference signal is transmitted repeatedly on the one symbol reserved for the DM-RS in each of the first and second slots of the subframe.

2. The method according to claim 1, wherein the additional sounding reference signal has a transmission period the same as that of the periodical sounding reference signal.
