Abstract: Aspects are provided which allow a UE to apply new radio high-speed train mode determination and false alarm suppression in HST deployments. The UE combines a plurality of indications associated with a high-speed train (HST) mode detection into a consolidated HST mode configuration signal. The UE determines whether to suppress the consolidated HST mode configuration signal based on a mobility metric of the UE and a plurality of thresholds. The UE transitions into a HST mode when the consolidated HST mode configuration signal is not suppressed based on the mobility metric of the UE exceeding at least one of the plurality of thresholds. As a result, false HST mode flags may be avoided and HST mode detection success rates may thereby be improved.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, during a beam management procedure, multiple sets of channel state information reference signals (CSI-RSs). The UE may receive multiple CSI-RSs, wherein one CSI-RS of the multiple CSI-RSs is associated with one set of CSI-RSs of the multiple sets of CSI-RSs, and wherein a beam associated with the one CSI-RS corresponds to a beam associated with the one set of CSI-RSs. The UE may transmit multiple channel quality indicator (CQI) reports based at least in part on the multiple CSI-RSs, wherein one CQI report of the multiple CQI reports is based at least in part on the one CSI-RS of the multiple CSI-RSs. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive a configuration that configures transmission configuration indicator (TCI) states based at least in part on aperiodic channel state information reference signals (AP-CSI-RSs), where each TCI state includes a first resource that is an aperiodic tracking reference signal (AP-TRS) and a second resource that is an AP-CSI-RS. The UE may receive first downlink control information that triggers a first AP-CSI-RS resource set that includes AP-CSI-RSs that are each associated with a quasi-co-location (QCL) Type-D resource. The UE may transmit a report that indicates one or more AP-CSI-RSs. The UE may receive an activation command that activates a TCI state associated with a first narrow beam, where a combination of a first AP-CSI-RS and a first associated QCL Type-D resource uniquely indicates the first narrow beam. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may estimate a throughput requirement associated with a communication between the UE and a network node. The UE may select a beam level, of multiple candidate beam levels capable of satisfying the throughput requirement, that is associated with a lowest power consumption. The UE may communicate with the network node using the beam level. Numerous other aspects are described.

Abstract: Apparatus, methods, and computer-readable media for facilitating UE beam selection based on service demands are disclosed herein. An example method of wireless communication includes determining to select an UL beam having a higher EIRP capability than an EIRP capability associated with a current beam for transmitting on UL when at least one of a target transmit power based on a TPC exceeds an EIRP capability associated with the current beam or when an amount of data in a buffer of the UE is greater than a data threshold. The example method also includes determining, upon determining to select the UL beam, a set of UL beams with an EIRP capability satisfying an EIRP capability threshold and a respective beamforming direction corresponding to a beamforming direction associated with the current beam, selecting one UL beam of the set of UL beams, and transmitting on UL on the selected UL beam.
