Abstract: A network may transmit either beam deployment information or beam number information to a user equipment (UE) carried on a train and configured for operation in the millimeter wave band. The deployment information may include deployment related distance parameters or azimuth angle spread parameters. The beam number information may indicate a number of network beams associated with a current cell. The UE may determine a number of UE receive beams based on deployment information or the network-indicated number of network beams. The UE may transmit feedback to the network, indicating the number of UE receive beams. Alternatively, the network may send a configuration message indicating a first number of UE receive beams to the UE, which the UE may treat as an upper bound or lower bound in its determination of a desired number of UE receive beams. The UE may transmit the desired number to the network.

Abstract: Provided is a method for a user equipment (UE). The UE obtains a physical uplink control channel (PUCCH) secondary cell (SCell) activation command from a primary cell (PCell) or primary secondary-cell-group cell (PSCell). The PUCCH SCell activation command is used for an PUCCH SCell activation of a target PUCCH SCell for the UE. The UE performs PUCCH SCell activation operations associated with a valid timing advance (TA) and the PUCCH SCell activation command. TA is considered to be a valid TA when the TA meets a preset criterion. The UE generates a channel state information (CSI) report for transmission to at least one of the PCell, PSCell and the target PUCCH SCell. The CSI report indicates that the PUCCH SCell activation is completed.

Abstract: Logic may receive an initial communication from a user device, the initial communication comprising capabilities. Logic may determine, based on an indication of a capability to support new radio frequency layers from the capabilities for the user device, a measurement gap configuration for the new radio frequency layers and a measurement gap configuration for a channel state information reference signal. Logic may send a frame with a preamble to a physical layer comprising the measurement gap configuration. Logic may send an initial communication to a physical layer, wherein the initial communication comprises capabilities for a user device. Logic may decode downlink data with a measurement gap configuration. And logic may parse the measurement gap configuration to determine at least one measurement gap identification and at least one offset for the new radio frequency layers and a channel state information reference signal.

Abstract: A user equipment (UE) device is disclosed. The UE device comprises a processor configured to perform operations comprising receiving a downlink control information (DCI) from a base station. In some embodiments, the DCI comprises an indication to trigger a Type-3 hybrid automatic repeat request (HARQ) acknowledgement (ACK) feedback signal. The operations further comprise generating the Type-3 HARQ ACK feedback signal, based on processing the DCI. In some embodiments, the Type-3 HARQ ACK feedback signal comprises one or more HARQ-ACK bits for semi-persistent scheduling (SPS) physical downlink shared channel (PDSCH) release(s). In some embodiments, each of the one or more HARQ-ACK bits for SPS PDSCH release(s) is adapted to include HARQ-ACK information for an SPS PDSCH release associated with the UE. Further, the operations comprise sending the Type-3 HARQ-ACK feedback signal to the base station.

Abstract: Features for increasing sounding reference signal (SRS) resource capacity for wireless communications may include introducing a larger comb size with comb hopping, providing support to determine the slot offset and/or comb offset for aperiodic SRS based on downlink control information (DCI) alone or based on both DCI and radio resource control (RRC), applying RB level frequency hopping within an SRS resource across different symbols, and/or applying time domain orthogonal cover code (TD-OCC) to symbols within an SRS resource. The TD-OCC may be applied to SRS for codebook, non-codebook and antenna switching, and may also be applied simultaneously with comb hopping and/or RB level hopping in certain scenarios.

Abstract: Apparatuses, systems, and methods for user equipment device (UE) uplink antenna panel selection. The UE may determine, based on at least one condition, to perform a beam switch from a current beam being used for communications with a base station. The UE may transmit, to the base station, an indication of an antenna panel status that may include an indication of a latency associated with the beam switch. The UE may receive, from the base station, an indication to switch to a target beam and to perform the switch, based on the indication, to the target beam. The indication of the antenna panel status may include a beam switching latency level for each beam in a beam report, a beam switch request that may indicate the target beam, and/or a beam switch request that may indicate that an antenna panel switch is to be applied by the UE.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform URLLC scheme selection. The UE may connect to at least one base station. The UE may determine scheduling of a physical downlink control channel (PDCCH) and a physical downlink shared channel (PDSCH) are within a threshold duration. Based on the PDCCH and the PDSCH being scheduled within the threshold duration, select one or more transmission control indicator (TCI) states for receiving the PDSCH irrespective of TCI state(s) indicated in the PDCCH. The UE may receive the PDSCH using the selected one or more TCI states.
