Abstract
A wireless device receives a radio resource control message comprising an aperiodic sounding reference signal (SRS) subframe parameter. A downlink control information is received. The downlink control information indicates uplink resources in a plurality of scheduled consecutive subframes for transmission of transport blocks by the wireless device and triggers an SRS transmission in a subframe of the plurality of scheduled consecutive subframes. The SRS is transmitted in the subframe. A position of the subframe in the plurality of scheduled consecutive subframes is determined based on the aperiodic SRS subframe parameter.
Claims20
A method comprising:
- receiving, by a wireless device, a radio resource control message comprising an aperiodic sounding reference signal (SRS) subframe parameter;
- receiving a downlink control information:
- indicating uplink resources in a plurality of scheduled consecutive subframes for transmission of transport blocks by the wireless device;
- and
- triggering an SRS transmission in a subframe of the plurality of scheduled consecutive subframes;
- and
- transmitting the SRS in the subframe, wherein a position of the subframe in the plurality of scheduled consecutive subframes is determined based on the aperiodic SRS subframe parameter.
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 a radio resource control message comprising an aperiodic sounding reference signal (SRS) subframe parameter;
- receive a downlink control information:
- indicating uplink resources in a plurality of scheduled consecutive subframes for transmission of transport blocks by the wireless device;
- and
- triggering an SRS transmission in a subframe of the plurality of scheduled consecutive subframes;
- and
- transmit the SRS in the subframe, wherein a position of the subframe in the plurality of scheduled consecutive subframes is determined based on the aperiodic SRS subframe parameter.
A system comprising:
- a base station comprising:
- one or more first processors;
- and
- first memory storing first instructions that, when executed by the one or more first processors, cause the base station to:
- transmit a radio resource control message comprising an aperiodic sounding reference signal (SRS) subframe parameter;
- transmit a downlink control information;
- and
- a wireless device comprising:
- one or more second processors;
- and
- second memory storing second instructions that, when executed by the one or more second processors, cause the wireless device to:
- receive the radio resource control message;
- receive the downlink control information, wherein the downlink control information:
- indicates uplink resources in a plurality of scheduled consecutive subframes for transmission of transport blocks by the wireless device;
- and
- triggers an SRS transmission in a subframe of the plurality of scheduled consecutive subframes;
- and
- transmit the SRS in the subframe, wherein a position of the subframe in the plurality of scheduled consecutive subframes is determined based on the aperiodic SRS subframe parameter.
