1. 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 indicating:
a first configuration of first sounding reference signals (SRSs) used in a first state in which the wireless device monitors downlink control channels associated with a shared data channel to determine whether data is scheduled for the wireless device, wherein the first configuration indicates first SRS radio resources of the first SRSs;
a second configuration of positioning SRSs used in a second state in which the wireless device does not monitor the downlink control channels, wherein the second configuration indicates second SRS radio resources of the positioning SRSs;
a first bandwidth part (BWP) configuration of a first BWP for the first state; and
a second BWP configuration of a second BWP for the second state;
transmit, in the first state and via the first SRS radio resources in the first BWP of a cell, the first SRSs; and
transmit, in the second state and via the second SRS radio resources in the second BWP of the cell, the positioning SRSs.
