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.

Abstract: The present disclosure relates to devices, apparatuses, and methods for enhanced PHR reporting in support of UE antenna scaling. A wireless device, which comprises at least one antenna array each comprising a plurality of antenna elements may perform antenna scaling by activating or deactivating at least one of the plurality of antenna elements (with corresponding RF chains) of one or more antenna arrays. The wireless device may generate a power headroom (PHR) report based at least on a difference between beamforming gains obtained after the antenna scaling and before the antenna scaling. The wireless device may then send the PHR report to a base station in communication with the wireless device.

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: Methods and systems are disclosed for a UE to manage and measure intra-cell cross link interference (CLI) when served by a base station operating in full-duplex FDD. The signaling may indicate to a victim UE resources to measure to determine the level of CLI from aggressor UEs. The resources used for the CLI measurement may be resources not scheduled by the base station for use by the victim UE for downlink reception, but are scheduled for use by the aggressor UEs for transmitting uplink traffic or for transmitting reference signals used to characterize the uplink channel. The victim UE may report the CLI measurements to the base station for the base station to adjust scheduling of downlink resources to the victim UE. In one aspect, the signaling from the base station may indicate to the victim UE the locations of scheduled downlink symbols that may potentially be impacted by CLI.
