Abstract: Aspects of this disclosure provide techniques for detecting and recovering from beam-failure events. In some embodiments, motion sensor information generated by motion sensors on a UE is used to detect, predict, and/or recover from a beam failure event that results, or would otherwise result, from movement of the UE. The motion sensor information may be used to adjust a current beam direction used by the UE to transmit or receive a signal, or to determine a recommendation for adjusting a current beam direction of the base station. The motion sensor information may be generated by any sensor that detects a movement of the UE, such as a gyroscope, an accelerometer, a magnetometer, a global positioning system (GPS) sensor, a global navigation satellite system (GNSS) sensor, or any other device that detects a change in position/orientation of the UE.

Abstract: A method for sending a beam failure recovery request (BFRQ) includes setting a demodulation symbol to a first value to specify a BFRQ signal, encoding the demodulation symbol with a first orthogonal code sequence, thereby producing an encoded first sequence of symbols, and send the encoded first sequence of symbols on a first physical uplink control channel (PUCCH) resource allocated for a first scheduling request (SR) transmission.

Abstract: The disclosure relates to technology for assigning resources to user equipment for a beam failure recovery by a base station. The base station identifies a beam failure random access channel (BRACH) resource holding beam correspondence with a synchronization signal (SS) block resource covering the user equipment, and assigns the user equipment one or more BRACH preambles for each BRACH resource assigned to the user equipment, excluding the BRACH resource holding beam correspondence with the SS block resource covering the user equipment.

Abstract: A method for reporting beam information includes setting, by a user equipment (UE), a report type of a beam information report, wherein the beam information report includes beam indices of communications beams being reported, a reference beam quality measurement of one of the communications beams reported, and a report type field conveying the report type, and sending, by the UE to an access node, the beam information report.

Abstract: A method for operating a user equipment includes receiving a first frame on a first channel associated with a first beam identified during a beam failure recovery procedure, and determining that an assumed quasi-co-located relationship exists between the first channel and the first beam, and based thereon, decoding the first frame in accordance with a first reference signal on the first channel and using a first spatial domain receive filter that was used to decode the first beam.

Abstract: A method for operating an access node includes receiving a first random access preamble in a first random access resource, wherein the first random access preamble and the first random access resource at least partially identifies a first beam selected by a user equipment (UE), and wherein the first random access resource is one of a plurality of random access resources assigned to the UE, and determining that first additional information associated with the first beam is needed, and based thereon, sending a first message responsive to the first random access preamble, the first message including a first information set to request the additional information associated with the first beam, and receiving a second message including the first additional information associated with the first beam.
