Abstract
A wireless device receives a downlink control information (DCI) indicating uplink resources in one or more subframes. The DCI comprises a field indicating a position of a subframe in the one or more subframes for transmission of a sounding reference signal (SRS). The wireless device transmits the SRS in the subframe.
Claims20
A method comprising:
- receiving, by a wireless device, one or more radio resource control (RRC) messages comprising configuration parameters for a licensed assisted access (LAA) cell, the configuration parameters comprising one or more sounding reference signal (SRS) parameters;
- receiving a downlink control information (DCI) indicating uplink resources in a number of one or more consecutive subframes of the LAA cell, the DCI comprising:
- a first field indicating the number of the one or more consecutive subframes;
- a second field indicating a position of a first subframe in the one or more consecutive subframes for transmission of an SRS;
- and
- a third field indicating a listen-before-talk (LBT) configuration;
- and
- transmitting, on the LAA cell and in the first subframe, the SRS when the wireless device is allowed to transmit in the first subframe according to an LBT procedure based on the LBT configuration.
5 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 (RRC) messages comprising configuration parameters for a licensed assisted access (LAA) cell, the configuration parameters comprising one or more sounding reference signal (SRS) parameters;
- receive a downlink control information (DCI) indicating uplink resources in a number of one or more consecutive subframes of the LAA cell, the DCI comprising:
- a first field indicating the number of the one or more consecutive subframes;
- a second field indicating a position of a first subframe in the one or more consecutive subframes for transmission of an SRS;
- and
- a third field indicating a listen-before-talk (LBT) configuration;
- and
- transmit, on the LAA cell and in the first subframe, the SRS when the wireless device is allowed to transmit in the first subframe according to an LBT procedure based on the LBT configuration.

- a first field indicating the number of the one or more consecutive subframes;
- and
- a second field indicating a position of a first subframe in the one or more consecutive subframes for transmission of an SRS;
- and
- receiving, by the base station and in the first subframe, the SRS on the LAA cell.
