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: User Equipments (UEs) may be assigned a set of aggregated component carriers for downlink carrier aggregation and/or carrier selection. Some UEs may be incapable of transmitting uplink signals over all component carriers in their assigned set of aggregated component carriers. In such scenarios, a UE may need to perform SRS switching in order to transmit SRS symbols over all of the component carriers. Embodiments of this disclosure provide various techniques for facilitating SRS switching. For example, a radio resource control (RRC) message may be used to signal a periodic SRS configuration parameter. As another example, a downlink control indication (DCI) message may be used to signal an aperiodic SRS configuration parameter. Many other examples are also provided.
