Abstract
A wireless device receives a radio resource control (RRC) message comprising an aperiodic sounding reference signal (SRS) subframe parameter. The wireless device receives a downlink control information (DCI) triggering an SRS transmission and indicating uplink resources in consecutive subframes. The wireless device determines a position of a subframe in the consecutive subframes based on the aperiodic SRS subframe parameter. The wireless device transmits the SRS via the subframe.
Claims20
A method comprising:
- receiving, by a wireless device, one or more radio resource control messages comprising an aperiodic sounding reference signal (SRS) subframe parameter;
- receiving a downlink control information indicating uplink resources in consecutive subframes, the downlink control information triggering a transmission of an SRS and comprising a listen-before-talk (LBT) configuration for an LBT procedure;
- determining a position of a first subframe in the consecutive subframes based on the aperiodic SRS subframe parameter;
- and
- transmitting, via the first subframe, the SRS based on the LBT procedure indicating a clear channel.
2 more elements
A wireless device comprising:
- one or more processors;
- and
- memory storing instructions that, when executed by the one or more processors, cause the wireless device to:
- receive one or more radio resource control messages comprising an aperiodic sounding reference signal (SRS) subframe parameter;
- receive a downlink control information indicating uplink resources in consecutive subframes, the downlink control information triggering a transmission of an SRS and comprising a listen-before-talk (LBT) configuration for an LBT procedure;
- determine a position of a first subframe in the consecutive subframes based on the aperiodic SRS subframe parameter;
- and
- transmit, via the first subframe, the SRS based on the LBT procedure indicating a clear channel.
