Various arrangements for transitioning the bandwidth allocation of a base station are presented. Four bandwidth parts may be defined for communication with the base station. At a given time, two of these bandwidth parts may be actively used for communication by different UE for communication with the base station. In response to network traffic, a determination to adjust a bandwidth allocation may be made. A series of transitions may be performed to migrate from the first two of these bandwidth parts to the second two of the bandwidth parts such that interference does not occur.
