1. A non-transitory machine-readable medium having executable instructions to cause one or more processing units to perform a method to switch to a new bandwidth part on a wireless link between a user equipment and a base station, the method comprising:
receiving an indication to switch to the new bandwidth part for the user equipment on the wireless link from the base station;
switching to the new bandwidth part for the user equipment;
signaling, to the base station, that the switching to the new bandwidth part has occurred in a time period smaller than a predefined time period, wherein the time period is determined using a time taken to send a feedback for the indication of the new bandwidth part switching; and
communicating information on the wireless link using the new bandwidth part prior to the expiration of the predefined time period.
