    摘要： Systems and methods for beam failure recovery (BFR) are disclosed herein. A user equipment (UE) receives downlink (DL) reference signal(s) on corresponding beam(s) from a base station. The UE performs beam failure detection (BFD) on such beams used for user data to determine whether a beam failure has occurred, and candidate beam detection (CBD) on such beams not used for user data to identify candidate beams for recovering from the beam failure. The BFD and the CBD are based on both uplink (UL) channel performance considerations and DL channel performance considerations, as determined using the DL reference signal(s), such that a beam failure may be determined in the UL, the DL, or both, and a candidate beam may be identified for UL, DL, or both. The UE sends a beam failure recovery request BFRQ with this information to the base station, and the system changes beams accordingly.

    摘要： A user equipment (UE) is configured to communicate with one or more transmission and reception points (TRPs). The UE receives a sounding reference signal (SRS) resource set configuration including a first resource set corresponding to a first transmission and reception point (TRP) and a second resource set corresponding to a second TRP, receives a downlink control information (DCI) transmission including an SRS resource indicator (SRI) indicating (i) which resource from the first resource set should be selected for a first physical uplink shared channel (PUSCH) transmission to a first TRP, and (ii) which resource from the second resource set should be selected for a second PUSCH transmission to a second TRP and transmits the first PUSCH transmission to the first TRP and the second PUSCH transmission to the second TRP.

    摘要： A user equipment (UE) configured to report Channel State Information (CSI) to a wireless network. The UE transmits a first sounding reference signal (SRS) on an uplink (UL) channel, receives a first channel state information reference signal (CSI-RS) on a downlink (DL) channel, wherein the first CSI-RS includes a first configuration of CSI-RS parameters based on the first SRS, performs first CSI-RS measurements based on the first configuration of CSI-RS parameters, transmits a first CSI report including the first CSI-RS measurements, transmits a second SRS on the UL channel, receives a second CSI-RS on the DL channel, wherein the second CSI-RS includes a second configuration of CSI-RS parameters based on the second SRS, performs second CSI-RS measurements based on the second configuration of CSI-RS parameters and transmits a second CSI report including the second CSI-RS measurements.

    摘要： Some aspects of this disclosure relate to apparatuses and methods for implementing techniques for generating a report result based on a set of measurements performed at measurement gaps during a reporting period. The set of measurements are performed on a reference signal at a first bandwidth part (BWP) or a second BWP when BWP switching is performed. The first BWP has a first measurement gap configuration, the second BWP has a second measurement gap configuration. The measurement gaps of the reporting period are configured according to a third measurement gap configuration that is determined based on the first measurement gap configuration and the second measurement gap configuration.
