A method and apparatus are provided for transmitting and receiving an SRS. The method includes determining a number of SC-FDMA symbols in an UpPTS; receiving index information for an SRS; determining an SRS offset and an SRS period, based on the index information; and transmitting the SRS, based on the SRS offset and the SRS period. If the index information includes an integer from 10 to 644, the SRS period is selected among 5 ms to 320 ms. If the index information includes an integer from 0 to 9, the SRS is transmitted twice, the SRS offset is based on an offset index table, 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 UpPTS includes one SC-FDMA symbol, the 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 and an SRS period, based on the index information; and transmitting the SRS, based on the SRS offset and the SRS period, wherein, if the index information includes an integer from 10 to 644, the SRS period is selected among 5 ms, 10 ms, 20 ms, 40 ms, 80 ms, 160 ms, and 320 ms, wherein if the index information includes an integer from 0 to 9,
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 UpPTS includes one SC-FDMA symbol, the first symbol is indicated by the SRS offset 1, and wherein if the index information includes the integer from 0 to 9, the SRS is transmitted twice in a period of 5 ms, and the SRS offset indicated by the index information is based on:IndexOffset00, 110, 221, 230, 341, 350, 461, 472, 382, 49 3, 4. |
