According to an aspect, a wireless device is configured to selectively operate in one of two or more previously configured bandwidth parts (BWPs), each BWP being a different subset of an available bandwidth for uplink and/or downlink operation. The wireless device receives an indication to switch from use of a first BWP to a second BWP, and after switching to use of the second BWP, applies a predetermined default configuration, corresponding to the second BWP, to one or more physical layer parameters and/or procedures.
