Method for transmitting sounding reference signal in multiple antenna wireless communication system and apparatus therefor

摘要

A method for transmitting sounding reference signals by a user equipment (UE) in a wireless communication system. The method according to one embodiment includes configuring an initial cyclic shift (CS) value and an initial comb value via a higher layer; setting a comb value for at least one antenna port; and transmitting the sounding reference signals using the comb value via at least one antenna port.

1. A method for transmitting sounding reference signals by a user equipment (UE) in a wireless communication system, the method comprising:
configuring an initial cyclic shift (CS) value and an initial comb value via a higher layer; setting a comb value for at least one antenna port according to a following Equation A:kTC(p~)={1-k_TCif⁢⁢nSRScs∈{4,5,6,7}⁢⁢and⁢p~∈{1,3}⁢⁢and⁢⁢Nap=4k_TCotherwise where {tilde over (p)} is an antenna port index, kTC({tilde over (p)}) is the comb value for the antenna port index {tilde over (p)}, nSRScs is the initial CS value, kTC is the initial comb value, and Nap is a number of the at least one antenna port; and transmitting the sounding reference signals using the comb value via at least one antenna port.
