1. A network node configured to communicate with a wireless device, the network node comprising:
processing circuitry configured to cause signaling of switching information for Bandwidth Part (BWP) switching to the wireless device, the signaling of switching information being absent of shared channel scheduling information, and the signaling of switching information pre-configuring the wireless device for the BWP switching such that the wireless device responsively switches from an active BWP to a specified BWP other than a default BWP at least (i) after having successfully completed a physical downlink shared control channel, PDCSH, reception, or (ii) having successfully completed a physical uplink control channel, PUCCH, transmission.
