Bandwidth part switching and PHY configuration alignment

Abstract:

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 (802) an indication to switch from use of a first BWP to a second BWP, and after switching to use of the second BWP, applies (804) a predetermined default configuration, corresponding to the second BWP, to one or more physical layer parameters and/or procedures.
