Title
(EN) Method and apparatus of transmitting sounding reference signal in multiple antenna system
Abstract
(EN)

A method and an apparatus of transmitting a sounding reference signal by a user equipment is provided. A user equipment transmits a first sounding reference signal through a first antenna, and transmits a second sounding reference signal through a second antenna. Resources for transmitting the first sounding reference signal and the second sounding reference signal are partially different.
