The present disclosure relates to switching of bandwidth parts in wireless communication network. Embodiments may provide a method performed by a wireless device for switching of bandwidth parts. The method comprises: receiving (1501) a first message from a base station indicating a first physical uplink control channel; receiving (1502) a second message from the base station indicating switching from a first bandwidth part to a second bandwidth part; in response to the second message, switching (1504) to the second bandwidth part for communication with the base station, with a utilization of the first physical uplink control channel A radio resource, such as a physical uplink control channel may be allocated previously to the wireless device, thus, service interruptions for the wireless device during the switch of bandwidth part may be reduced.
