Abstract

Method, apparatus, and computer program product for a CORESET beam recovery procedure and a QCL association beam recovery procedure where a condition or rule based UE initiated change of active TCI state is used. The CORESET beam recovery procedure involves a downlink reference signal corresponding to a transmission configuration indication state activated for certain CORESET being determined as a beam failure detection resource. The QCL association beam recovery procedure concerns a UE transmitting a UL request signal to require switching an active TCI state of the CORESET to a currently deactivated TCI state of the same CORESET.
