Abstract: A beam failure caused by an event initiated by the UE such as folding of the UE or shutting down of a UE antenna penal may be predictable. Accordingly, the UE may declare a beam failure detection (BFD) without going through a potentially long detection procedure. Disclosed herein are apparatus and methods for detecting beam failure and terminating BFD earlier than the current DFD process would have. The method may include identifying a beam failure (BF) event at the UE that impacts at least one beam pair link (BPL) and communicating a request to an associated base station to stop communicating on an impacted beam pair link, without going through an entire BFD process.
