    Abstract: Systems and methods disclosed herein relate to acknowledgement signaling sent by a user equipment (UE) in response to downlink control information (DCI) received from a base station that schedules the use of multiple physical uplink control channels (multi-PUSCH) or multiple physical downlink control channels (multi-PDSCH). Acknowledgement signaling may inform the base station that DCI scheduling the multi-PUSCH/multi-PDSCH was received (or not), so that the base station may reclaim those scheduled resources in the case that the UE remains unaware of them. Methods for performing this signaling include, e.g., the use of HARQ-ACK codebooks (whether in a semi-static or dynamic manner), and aperiodic sounding reference signals (A-SRS). Embodiments involving such DCI received across multiple component carriers of different serving cells of the UE are contemplated. Acknowledgment signaling according to multi-PUSCH/multi-PDSCH subgroups, monitoring windows, acknowledgment signaling enablement/disablement, and the use of DCI to trigger acknowledgment signaling are also discussed.

    Abstract: A first cellular base station (102) transmits a configuration message to a reporting device installed on a high-speed vehicle. The configuration message specifies one or more parameters of a Doppler measurement report. The reporting device performs one or more first Doppler measurements on the first base station (102) and/or one or more second Doppler measurements on a second base station (102). The reporting device transmits the Doppler measurement report to the first and/or second base stations (102). The Doppler measurement report may be used by the first and/or second base stations (102) to perform Doppler pre-compensation on transmissions to the reporting device.

    Abstract: A base station configures a user equipment (UE) to perform measurements. The base station configures the UE for at least one channel state information (CS I) measurement report including an indication of first reference s ignal (RS) resources for a first transmission and reception point (TRP) and second RS resources for a second TRP, the first RS resources comprising a first plurality of beamformed RS and the second RS resource comprising a second plurality of beamformed RS to be received simultaneously at the UE, wherein the UE is further configured to select a first beam from the first plurality of beamformed RS and a second beam from the second plurality of beamformed RS and receives the at least one CSI measurement report comprising measurements for the first beam and the second beam.

    Abstract: Switching schemes at a mobile device may include, in response to being within range of a transmission and reception point (TRP) of a plurality of TRPs associated with a high speed train (HST), decoding a communication received from a network. The communication may include a first radio resource control (RRC) information element (IE) having an HST configuration associated with an HST scheme. The HST configuration may be applied to thereby operate using the HST scheme. In response to being out of range of the plurality of TRPs associated with the HST, a communication received from the network may be decoded. The communication may include a second RRC IE having a non-HST configuration associated with a non-HST scheme. The non-HST configuration may be applied to thereby operate using the non-HST scheme.
