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: A base station (BS) comprising a processor configured to perform operations is described. In an exemplary embodiment, the operations include receiving an initial data from a UE is in a RRC_INACTIVE while the UE does not transition from the RRC_INACTIVE state to a RRC_CONNECTED state. In addition, the operations include transmitting a physical downlink control channel (PDCCH) for a UE dedicated scheduling for a transmission or reception of a subsequent data during an active period, while the UE is in the RRC INACTIVE state. Furthermore, the operations include receiving or transmitting the subsequent data transmission based on the dedicated scheduling. The operations additionally include transmitting one or more configurations for the transmission or reception of the subsequent data. The one or more configurations is transmitted as part of the RRC release message. The one or more configurations is transmitted as part of a System Information Block (SIB).

Abstract: The present application relates to beam failure recovery in a cell that includes multiple transmission and reception points (TRPs). In an example, a UE can perform a beam failure detection (BFD) procedure to detect, per TRP, whether a beam failure occurs. The UE can also perform one or more beam failure recovery (BFR) procedures based on the number of beam failures, the type of cell, and/or other related information.

Abstract: Systems and methods for enhancing the use of pre-emptive buffer status reports (pre-BSRs) in wireless communications systems implementing integrated access and backhaul (IAB) networks are disclosed herein. In some cases, an IAB node can re-classify the LCGs of one or more incoming data flows according to such pre-BSR usage. This may involve the use of and extended medium access control (MAC) control element (MAC CE) having more LCG bits than previously contemplated, having sub-LCG bits, or that includes further LCG classification information bits. Other embodiments use a priority index for LCGs in an extended pre-BSR MAC CE. The priority index may include one or more of a priority field, a prioritized bit rate (PBR), and/or a bucket size duration (BSD) that is reported to an IAB donor. Other embodiments leverage the provision of additional grants from an IAB node to a child IAB node to reduce unwanted pre-BSR effects.

Abstract: Systems, methods, and circuitries are provided for direct transmission of uplink data by an INACTIVE UE using a contention free random access (CFRA) process. In one example, a method, includes, receiving, from a network, configuration of a dedicated physical random access channel (PRACH) resource or a dedicated preamble resource (dedicated PRACH/preamble resource); and while in a radio resource control (RRC) INACTIVE state, without entering an RRC CONNECTED state, using a contention-free random access (CFRA) process to transmit uplink data to a base station using the dedicated PRACH/preamble resource.

Abstract: A system for determining and reporting user equipment (UE) time gap requirement information for performing a measurement on a reference signal provided by a target base station. A UE receives a radio resource control (RRC) message from a current base station to modify a current RRC connection. The RRC configuration message may comprise sub carrier spacing (SCS) information of one or more target frequency bands of at least one target base station. The UE may then determine gap information based at least in part on the received SCS information of the one or more target frequency bands. The gap information may indicate whether a gap is needed in performing measurements on a reference signal transmitted at each of the one or more target frequency bands. The UE then transmits the gap information to the current base station.

Abstract: Apparatuses, systems, and methods for overhead reduction for multi-carrier beam selection and power control. A user equipment device (UE) may receive an uplink beam configuration for a group of component carriers and may communicate using the uplink beam configuration for the group of component carriers. The UE may receive an updated uplink beam configuration for the group of component carriers. The update uplink beam configuration may include a medium access control (MAC) control element (CE) that may update a pathloss reference signal for the group of component carriers. The MAC CE may include an indication of a spatial relation for aperiodic or semi-persistent sounding reference signals for the group of component carriers, an indication of a transmission control indicator for a physical downlink control channel, an indication of an update for a physical uplink shared channel, and/or an indication of an update for a sounding reference signal.

Abstract: An example method for wireless communication includes: receiving, by a user device in a reduced power state, resource information for receiving a channel state information reference signal (CSI-RS) and tracking reference signal (TRS); exiting the reduced power state to receive the CSI-RS and TRS, based on the resource information; synchronizing with a base station, based on the received CSI-RS and TRS, to receive a downlink control information message; receiving paging information in a first physical downlink shared channel (PDSCH) transmission based on the received downlink control information message; determining whether there is paging information in the first PDSCH transmission for the user device; starting a Random Access Channel (RACH) procedure to make a Radio Resource Control (RRC) connection, based on determining that there is paging information for the user device; and returning to the reduced power state, based on determining that there is not paging information for the user device.
