Patent number: 11671158Abstract: Methods, systems, and devices for wireless communication are described that support beam failure determination based on a dynamic range of transmission power ratios between two reference signals (e.g., between a channel state information reference signal (CSI-RS) and a demodulation reference signal (DMRS) of a physical downlink control channel (PDCCH)). A wireless device may identify the dynamic range of transmission power ratios that may be used by a base station (e.g., via indications of maximum and minimum transmission power ratios, indications of one or more offsets from some average transmission power ratio, etc. sent from the base station). The wireless device may use the identified dynamic range of transmission power ratios, along with a CSI-RS measurement, to determine a range of hypothetical block error rates (BLERs). Values within the range of hypothetical BLERs may be compared to a threshold in order to determine a beam failure status (e.g., a beam failure).Type: GrantFiled: October 25, 2018Date of Patent: June 6, 2023Assignee: QUALCOMM IncorporatedInventors: Chenxi Hao, Alexandros Manolakos, Tao Luo, Yu Zhang
