Abstract: A network device (e.g., a user equipment (UE), a new radio NB (gNB), or other network component) can process or generate a configured grant transmission based on a logical channel. A selection of at least one of: an uplink (UL) or a supplementary UL (SUL) can be configured to be utilized for a CG transmission on an uplink channel based on the selected CG and a consistency test for determining interfering or colliding transmission with the CG transmission.

Abstract: Improved network configuration options enable reduced capability (Redcap) devices to coexist with legacy devices. A master information block (MIB) cellBarred indication received in a Synchronization System Block (SSB) by a Redcap device may be ignored by the Redcap device, which may read a System Information Block1 (SIB1) to determine whether to connect to the cell defined by the received SSB. The Redcap device may consider the cell barred if the SIB1 includes a cellBarred indication targeting Redcap devices. The Redcap device may alternately search for an alternative SSB indicated by the SIB1 to determine whether to connect to the cell defined by the alternative SSB. A network node may broadcast Redcap specific and legacy specific SSBs at the same frequency location in a time-multiplexed manner, with each type of device determining cell access based on the received specific SSB. The network node may transmit SSB bursts specifically targeting Redcap devices.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and/or cellular network to perform to perform capability updates. Under at least some circumstances, the UE may use a non-cellular (e.g., non-3GPP) access to transmit updated capability information to a cellular network. Elements of the core of the cellular network may provide an identifier corresponding to the updated capability information to the UE for use in future registrations with the cellular network. Further, the core network may provide the updated capability information to a cellular radio access network associated the cellular network. The UE and the cellular network may communicate according to the updated capability.

Abstract: Base stations, user equipment devices (UEs), and methods for a base station to supply service type-specific information to the UE. The base station may broadcast a first system information block (SIB) comprising scheduling information for a plurality of second SIBs, wherein each of the plurality of second SIBs corresponds to a respective service type of a plurality of service types, and wherein the second SIBs describe service type-specific capabilities of the base station. The plurality of service types may comprise two or more of enhanced mobile broadband, ultra-reliable low latency communications, and massive machine-type communications. The base station may broadcast the plurality of second SIBs according to the scheduling information of the first SIB, and may establish a connection and communicate with the UE using one or more service types and according to the service type-specific capabilities described by second SIBs corresponding to the one or more service types.

Abstract: A service device (e.g., a user equipment (UE), or other network component) can operate generate sidelink communications with peer UE devices based on PC5 unicast link to enable a direct peer-to-peer communication as part of PC5 vehicle-to-everything (V2X) communications. Radio status link detection can be configured based on a keep alive (KA) coordination scheme via the PC5 unicast link to monitor a status of the PC5 unicast link. A KA timer can be configured based on the KA coordination scheme via the PC5 unicast link. The KA coordination scheme is configured to reduce redundant KA requests in the PC5 unicast link to coordinate the direct peer-to-peer communication across the PC5 unicast link.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for radio link monitoring for multiple DCI based transmissions. The UE may receive, from a network node, a configuration for multiple downlink control information (DCI) mode operation in which a physical downlink shared channel (PDSCH) is scheduled by multiple DCIs from a number of control resource sets (CORESETs). The number of CORESETs may exceed a number of CORESETs the UE can monitorable. The UE may determine a set of CORESETs to monitor based, at least in part, on one or more CORESET properties. The set of CORESETs to monitor may be less than the number of CORESETs. Additionally, the UE may monitor the set of CORESETs for at least one of a radio link failure or a beam failure.

Abstract: A transmitter (e.g. a packet data convergence protocol, PDCP, in the transmitter), which may be a base station for downlink communications or a user equipment device for uplink communications, may control timing of the delivery of duplicate (same) packets to multiple (e.g. two) wireless links (e.g. radio link control links) for transmission to a receiver, based at least on synchronization information received from the receiver. The duplicate packets may be transmitted over the multiple wireless links to the receiver, which may receive the duplicate packets over the multiple wireless links. The receiver may collect and/or generate synchronization information indicative of the timing or latency between the multiple wireless links, based at least on the respective receive timings of the duplicate packets over the multiple wireless links. The receiver may transmit a report containing the synchronization information to the transmitter periodically and/or in response to a trigger event.

Abstract: Apparatuses, systems, and methods for non-small data transmission (non-SDT) dedicated radio bearer (DRB) handling while in a radio resource control (RRC) inactive state. A wireless device may determine, while operating in the RRC inactive state, that non-SDT data is available for transmission on a non-SDT DRB and determine, based on one or more conditions, to transmit, to a base station, non-SDT data arrival information during SDT procedure. The one or more conditions may be associated with arrival time of the non-SDT data and/or an amount of non-SDT data to be transmitted. The arrival time may be relative to arrival of SDT data, initiation of an SDT procedure, and/or initiation of a subsequent transmission period of an SDT procedure.
