BEAM FAILURE RECOVERY ASSISTANCE IN UPPER BAND MILLIMETER WAVE WIRELESS COMMUNICATIONS

Abstract:

Methods, systems, and devices for wireless communications are described in which a first wireless device and second wireless device may establish communications using a first beam and a second beam. The first wireless device may perform separate radio link monitoring (RLM) procedures to monitor beam quality for each of a transmit beam and receive beam that are used for communications with a second wireless device. The separate RLM procedures may be used at the first wireless device to determine that one of the transmit or receive beams is experiencing a quality degradation or a radio link failure (RLF), and an RLF indication may be provided to the second wireless device.
