Abstract

The invention provides an SRS (Sounding Reference Signal) sending method and an SRS sending device when an LTE (Long Term Evolution) system works at a frame structure 3 within an unlicensed band and a terminal. The SRS sending method when the LTE system works at the frame structure 3 within the unlicensed band comprises: determining the type of a target sub-frame to send an SRS; selecting a target symbol for sending the SRS in the target sub-frame according to the type of the target sub-frame; and sending the SRS via the target symbol. By adopting the technical solution, when the LTE system works within the unlicensed band, normal sending of the SRS can be ensured, then the accuracy of uplink channel quality measurement can be ensured, and the uplink throughput of the LTE system can be improved.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular, to an SRS sending method when an LTE system works in an unlicensed frequency band with a frame structure 3, an SRS sending device when an LTE system works in an unlicensed frequency band with a frame structure 3, and A kind of terminal. Background technique [0002] At present, 3GPP proposes the concept of LAA (LTE Assisted Access, LTE Assisted Access), which is used to use unlicensed spectrum with the help of LTE (Long Term Evolution, Long Term Evolution) licensed spectrum. When an LTE network uses an unlicensed frequency band, one of the most important key points is to ensure that the LAA system can coexist with existing access technologies (such as Wi-Fi) on a fair and friendly basis. However, there is no LBT (Listen Before Talk, Listen Before Talk) mechanism in the traditional LTE system to avoid collisions. In order to better coexist with Wi-Fi, the LTE system ...
