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.

Abstract: This application sets forth techniques for mitigating radio frequency (RF) interference from wired connections on cellular wireless reception quality, including pre-emptively determining when to perform RF interference mitigation based on various factors. An interference mitigation module in the wireless device determines whether to perform an interference mitigation procedure based on active and/or imminent use of a high-speed wired connection port for data transfer in parallel with a cellular wireless connection that uses a mid-frequency RF band or a high-frequency RF band. The wireless device determines a target cell in a low-frequency RF band and biases measurement reports sent to a cellular wireless network to handover and keep the cellular wireless connection to the target cell in the low-frequency RF band while a high-speed wired connection is active.
