Patent number: 11950112Abstract: A UE for beam failure detection is provided. The RF signal processing device of the UE assesses a first radio link quality according to a first BFD-reference signal (BFD-RS) set including at least one reference signal, communicating with a plurality of transmission/reception points (TRPs) which include at least a first TRP and a second TRP. The processor of the UE is coupled to the RF signal processing device. When the first radio link quality is below a threshold, the processor generates a first indication, wherein the first indication is a first beam failure instance (BFI) or the first BFD-RS set. The processor enables a first timer and a first counter according to the first indication.Type: GrantFiled: July 12, 2021Date of Patent: April 2, 2024Assignee: ACER INCORPORATEDInventors: Li-Chung Lo, Chien-Min Lee
