Abstract

A method for a network node to adaptively configure bandwidth parts, BWPs, for a wireless device, WD, is provided. The method includes selecting at least one use case to be assigned to at least one BWP, the selecting being based at least in part on a WD context. The method further includes adaptively configuring at least one BWP for the WD based on the selected at least one use case. In addition, a method for a WD supporting communication with a network node is provided. Further, corresponding apparatuses for the network node and the WD are provided.
