ABSTRACT:
A method for transmitting an uplink sounding reference signal includes indexing Single Carrier Frequency Division Multiple Access (SC-FDMA) symbols within a single radio frame for transmitting a Sounding Reference Signal (SRS) as a number k, and calculating a value of nSRSaccording to number k and an index number of the radio frames for transmitting the SRS, determining an index number of a frequency-domain start sub-carrier mapped from time-domain SRS symbol with nSRS, and transmitting the SRS through the sub-carrier with the determined index number determined. Before transmitting the SRS, the start frequency position for SRS should be changed according to the specific frequency-hop pattern to guarantee that the UE may uniformly sound the entire SRS frequency-hop bandwidth after multiple soundings.
