Abstract: This disclosure relates to techniques for performing wireless communications by a network in communication with a UE that is moving rapidly. The network may adapt communication techniques in response to the UEs motion. For example, reference signals may be transmitted to the UE from additional transmission and reception points and/or using different configurations.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform downlink control information (DCI) mode signaling and control resource set (CORESET) selection. A DCI mode may be signaled based on a predefined rule, media access control (MAC) control element (CE), and/or group based beam reporting. One or more CORESETs may be selected based on configuration of an active bandwidth part (BWP), CORESET identifier, higher layer index, periodicity, type of search space, and/or MAC CE.

Abstract: Layer 2 handling during a cell change procedure includes decoding an RRC reconfiguration message received from a first cell. The RRC reconfiguration message includes a Layer 1 (L1) configuration corresponding to a second cell. The first cell and the second cell share an SDAP entity, a PDCP entity, an RLC entity, and a MAC entity. The first cell and the second cell have a separate L1 entity. In response to decoding the RRC reconfiguration message, the L1 configuration corresponding to the second cell is stored. A cell change message received from the first cell is decoded. The cell change message indicates that a cell change from the first cell to the second cell is to be performed. The stored L1 configuration corresponding to the second cell is applied for data transmission and reception associated with the second cell. A cell change to the second cell is initiated.

Abstract: A user equipment (UE) transmits concurrent channel state information (CSI) processing capability information to a base station. The capability information can take various forms, and is intended to constrain the base station in the types of CSI requests that can be made to the UE. For example, the UE may indicate different CSI processing capabilities for intra-CC and inter-CC cases and/or for different codebook types. The UE may also specify supported combinations of codebook types for concurrent CSI reporting. The UE may also specify maximum resources or weighting factors for different codebook types. The UE may further restrict the rank information it provides and use a priority rule for “dropping” CSI report data due to payload size restrictions. The base station may direct, or the UE may implement, improved utilization of CSI resources that are shared for multiple concurrent CSI reports. Minimum time requirements for CSI reporting may also be relaxed.

Abstract: Apparatuses, systems, and methods for multi-TRP by a UE, including out of order delivery of PDSCH, PUSCH, and/or DL ACK/NACK. The UE may receive, from a base station, a configuration that may include multiple control resource set (CORESET) pools and each CORESET pool may be associated with an index value. The UE may determine that at least two DCIs of the multiple DCIs end at a common symbol and determine, based on one or more predetermined rules, when the UE may be scheduled to receive PDSCHs, transmit PUSCHs, and/or transmit ACK/NACKs from CORESETs associated with the at least two DCIs.

Abstract: The present application relates to devices and components including apparatus, systems, and methods to provide SCell activation. In one example, an SCell activation procedure may be extended by a duration based on cancelation of CSI-RS reception. In another example, a base station may use particular configuration parameters to avoid cancelation of CSI-RS reception. In yet another example, a UE and a base station may use particular information for a CSI-RS reception/transmission on an SCell that is being activated.

Abstract: Techniques discussed herein can facilitate successful decoding of Physical Downlink Shared Channel (PDSCH) based on a reduced number of retransmissions. Based on a given PDSCH, embodiments discussed herein can communicate feedback (e.g., Hybrid Automatic Repeat reQuest (HARQ) feedback, Channel State Information (CSI) feedback) that indicates an amount of additional information that can allow a User Equipment (UE) to successfully decode the PDSCH. In some embodiments, the feedback can indicate a requested Redundancy Version (RV) sequence that can allow the UE to successfully decode the PDSCH. In other embodiments, the feedback can indicate the amount of additional information, based on which a receiving Base Station (BS) can select a RV sequence.
