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 plurality of consecutive subframes of the LAA cell for transmission of transport blocks (TBs) by the wireless device, the DCI comprising:
- a first field indicating the number of the plurality of consecutive subframes for transmission of the TBs by the wireless device;
- and
- a second field indicating which subframe, of the plurality of consecutive subframes for transmission of TBs by the wireless device, is for transmission of an SRS;
- and
- transmitting the SRS in the subframe of the LAA cell based on the wireless device being allowed to transmit in the subframe according to a listen before talk procedure.

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 plurality of consecutive subframes of the LAA cell for transmission of transport block (TBs) by the wireless device, the DCI comprising:
- a first field indicating the number of the plurality of consecutive subframes for transmission of the TBs by the wireless device;
- and
- a second field indicating which subframe, of the plurality of consecutive subframes for transmission of TBs by the wireless device, is for transmission of an SRS;
- and
- transmit the SRS in the subframe of the LAA cell based on the wireless device being allowed to transmit in the subframe according to a listen before talk procedure.
