Abstract: Methods and apparatuses are provided for sounding reference signal (SRS) transmission. A plurality of parameter sets are received for an aperiodic SRS transmission. First downlink control information is received comprising an SRS request field with a first value indicating one of the plurality of parameter sets. Second downlink control information is received comprising an SRS request field with a second value indicating one of the plurality of parameter sets. A transmission of an aperiodic SRS is determined based on whether the first value is identical to the second value.
