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

Abstract: A user equipment (UE) monitors a Physical Downlink Control Channel (PDCCH). The UE reports, to a base station, a reduced PDCCH monitoring capability for at least one group of search space sets (SSS) of a PDCCH, receives, from the base station, a reduced monitoring capability (MO) configuration, wherein the base station determines the reduced MO configuration based on the reported reduced PDCCH monitoring capability and monitors the PDCCH based on the reduced MO configuration.

Abstract: This disclosure relates to techniques for physical downlink control channel handling when a secondary cell group is activated in a wireless communication system. A wireless device may establish a wireless link with a master cell group. A secondary cell group may be configured. The wireless device may receive an indication to activate the secondary cell group without performing a random access channel procedure on the secondary cell group. The wireless device may determine quasi-co-located information for a physical downlink control channel of the secondary cell group. The wireless device may perform physical downlink control channel decoding for the physical downlink control channel of the secondary cell group using the determined quasi-co-located information.

Abstract: Techniques discussed herein can facilitate configuration of a User Equipment (UE) with two or more Discontinuous Reception (DRX) configurations. A first set of techniques can facilitate configuration of the UE with independent DRX configurations for Frequency Range 1 (FR1) and for Frequency Range 2 (FR2). A second set of techniques can facilitate configuration of the UE with independent DRX configurations for a first set of one or more Component Carriers (CCs) associated with a first frequency band of a supported band combination and for a second set of one or more CCs associated with a second frequency band of the supported band combination. Various embodiments can employ techniques of one or more of the first set of techniques or the second set of techniques.

Abstract: The present application relates to devices and components including apparatus, systems, and methods that support capability index reporting associated with multi-antenna panel uplink transmissions. In an example, a base station configures a UE to perform channel state information (CSI) group-based reporting. The UE can report a set of capability indexes that correspond to an antenna panel or for a plurality of antenna panels. This report can indicate the number of sounding reference signal (SRS) ports supported per corresponding antenna panel(s). Further, the reported capability indexes can be included in a CSI group-based report or in a standalone report.

Abstract: Systems and methods are provided for controlling behavior for overriding grants for channel state information (CSI) feedback. A user equipment (UE) may control override of a first grant of a first radio resource by a second grant of a second radio resource. The UE determines that the second radio resource at least partially overlaps with the first radio resource. The UE also determines a physical layer priority of the first grant of the first radio resource and the second grant of the second radio resource. The physical layer priority is based on at least one of the first grant of the first radio resource and the second grant of the second radio resource being configured for transmitting CSI feedback over a physical uplink shared channel (PUSCH) to a base station. The UE then generates a transmission according to the physical layer priority.

Abstract: Techniques discussed herein may better ensure efficient fine time tracking during a second cell (SCell) activation procedure by using a tracking reference signal (TRS) that is User Equipment (UE) specific. A primary cell (PCell) may provide a UE with a TRS configuration that includes a UE-specific reference signal (RS) with periodicity or aperiodicity. In response to receiving a SCell activation command from the PCell, the UE may perform cell activation with fine time tracking in accordance with the UE-specific RS. As the delay time for the UE-specific RS may be less than the delay time for a system synchronization block (SSB) from the SCell, use of the UE-specific RS may expedite the cell activation procedure.
