Abstract
The described embodiments regard detecting a bandwidth part (BWP) mismatch between a wireless device and a cellular wireless network base station and performing mitigation to correct for the BWP mismatch. The wireless device can detect a BWP mismatch, based on content of a downlink control information (DCI) message indicating to switch BWP configurations, which is inconsistent with a scheduled downlink resource or granted uplink resource indicated in the DCI message occurring before completion of a BWP switching delay time period. The wireless device can monitor for DCI messages, after switching BWP configurations, in accordance with a previous BWP configuration for a monitoring time period to confirm use of the new BWP configuration or to detect a BWP mismatch. Responsive to detecting a BWP mismatch, the wireless device switches back to the previous BWP configuration without waiting to complete the BWP switching delay time period for switching BWP configurations.
