    • 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 nSRS according 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.
    • 用于发送上行探测参考信号的方法包括在单个无线电帧内索引单载波频分多址(SC-FDMA)符号,用于发送作为数k的探测参考信号(SRS),并根据下式计算nSRS的值 数字k和用于发送SRS的无线电帧的索引号,确定从具有nSRS的时域SRS符号映射的频域起始子载波的索引号,并通过所确定的子载波发送SRS 指数确定。 在发送SRS之前,应根据特定的跳频模式改变SRS的起始频率位置,以保证UE可以在多次发现之后均匀地发送整个SRS频跳带宽。
