Method and apparatus for transmitting SRS in LTE TDD system

摘要

A method and apparatus are provided for transmitting and receiving an uplink Sounding Reference Signal (SRS). The method includes determining a number of single-carrier frequency division multiple access (SC-FDMA) symbols in an uplink pilot time slot (UpPTS); receiving index information for a sounding reference signal (SRS); determining an SRS offset, based on the index information; and transmitting the SRS, based on the SRS offset. If the index information includes an integer from 0 to 9, and if the UpPTS includes two SC-FDMA symbols, a first symbol is indicated by SRS offset 0 and a second symbol is indicated by SRS offset 1. If the index information includes an integer from 0 to 9, and if the UpPTS includes one SC-FDMA symbol, a first symbol is indicated by the SRS offset 1.

1. A method for wireless communication, the method comprising:
determining a number of single-carrier frequency division multiple access (SC-FDMA) symbols in an uplink pilot time slot (UpPTS); receiving index information for a sounding reference signal (SRS); determining an SRS offset based on the index information; and transmitting the SRS based on the SRS offset, wherein if the index information includes an integer from 0 to 9,
if the number of SC-FDMA symbols in the UpPTS is two, a first symbol is indicated by SRS offset 0 and a second symbol is indicated by SRS offset 1, andif the number of SC-FDMA symbols in the UpPTS is one, a first symbol is indicated by the SRS offset 1.
