Abstract
A method includes sequentially performing analog frequency conversion operations on a first digital frequency conversion signal and a second digital frequency conversion signal based on local oscillator signals at a same frequency, where the first digital frequency conversion signal corresponds to a first sounding reference signal (SRS) to be transmitted on a first carrier, and the second digital frequency conversion signal corresponds to a second SRS to be transmitted on a second carrier, transmitting the first SRS on the first carrier during a first time period, and transmitting the second SRS on the second carrier during a second time period, where the second time period is later than the first time period.
