Abstract
The present disclosure provides a Sounding Reference Signal (SRS) sending method when a Long Term Evolution (LTE) system works with a frame structure 3 in an unlicensed frequency band, a SRS sending device, and a terminal, and the SRS sending method when the LTE system works with the frame structure 3 in the unlicensed frequency band includes: determining a type of a target subframe to send a SRS; according to the type of the target subframe, selecting a target symbol in the target subframe for sending the SRS; sending the SRS through the target symbol. According to the technical solution of the present disclosure, when the LTE system works in the unlicensed frequency band, a normal transmission of the SRS can be ensured, thereby ensuring the measurement accuracy of the uplink channel quality, and improving the uplink throughput of the LTE system.
