Bandwidth Part (BWP) switching/operation can be done by several different ways such as:

Dedicated RRC Signaling
Over PDCCH channel Downlink control information (DCI)- DCI 0_1 (UL Grant) and DCI 1_0 (DL Scheduling)
By bwp-inactivityTimer – ServingCellConfig.bwp-InactivityTimer
By MAC CE (Control Element)

Reference: 3GPP 38.321-5.15

Typically UE will send SRS on configured BWP, however UE can be directed to send SRS beyond its BWP if UE supports larger BW.
