Abstract
A method, a computer-readable medium, and an apparatus are provided for wireless communication at a UE. The apparatus switches from a first, active BWP to a second, active BWP. Then, the apparatus measures a first radio link quality of a configured CORESET TCI or a beam failure detection RS upon switching to the second, active BWP. For example, the apparatus may switch the active BWP based on detecting an expiration of a BWP inactivity timer. The apparatus may then determine based on a threshold radio link quality whether to perform a measurement of a second radio link quality of a beam failure recovery candidate resource set or to continue to monitor the configured CORESET TCI in the second, active BWP.
