Problems solved by technology

When the terminal sends SRS to the base station, in order to ensure that the SRS can be sent successfully, it needs to perform LBT measurement every time it sends SRS, which seriously reduces the data throughput

Abstract

The embodiment of the invention discloses a method for transmitting channel sounding reference signals SRSs, a terminal and a base station. The method comprises following steps of receiving downlink service sent by the base station, wherein the downlink service is transmitted based on a target channel, and the target channel is the channel in an unlicensed frequency band; periodically sending the channel sounding reference signals SRSs to the base station, wherein the SRSs are used for sounding the channel quality of the target channel; judging whether the difference value between the deadline of the downlink service and the sending time of the SRSs is less than or equal to a preset threshold value or not when uplink service needs to be sent to the base station, wherein the SRSs are transmitted based in the target channel; not carrying out LBT sounding if the difference value is less than or equal to the preset threshold value; sending the uplink service to the base station; carrying out the LBT sounding if the difference value is more than the preset threshold value, wherein the LBT sounding is used for sounding the idle/busy state of the target channel; and sending the uplink service to the base station when the target channel is in an idle state. Through adoption of the method, the terminal and the base station, the times of carrying out LBT (Listen Before Talk) sounding can be reduced, and the data throughout can be improved.

Description

Technical field [0001] The present invention relates to the field of communication technology, in particular to a method, terminal and base station for transmitting a channel sounding reference signal SRS. Background technique [0002] With the rapid increase in mobile communication traffic, the authorized frequency bands in the 3GPP network are less and less satisfying the increasing traffic. In order to improve the efficiency of frequency resource utilization, the 3GPP organization proposed assisted access (English: LicensedAssisted Access, referred to as LAA) Technology to use unlicensed frequency bands with the help of licensed spectrum in Long Time Evolution (English: Long Time Evolution, LTE for short). The WiFi technology on unlicensed frequency bands eliminates interference between different WiFi devices through Carrier Sense Multiple Access / Collision Detection (English: Carrier Sense Multiple Access / Collision Detection, CSMA / CA). Before sending data, the WiFi device per...
