Abstract: Apparatuses, systems, and methods for a wireless device to perform master cell group failure recovery in a dual connectivity cellular communication system. The wireless device may establish a first wireless link to a cellular network via a first cell group. The first cell group may be configured as a master cell group for the wireless device. The wireless device may establish a second wireless link to the cellular network via a second cell group. The second cell group may be configured as a secondary cell group for the wireless device. The wireless device may determine that link failure for the first wireless link has occurred. The wireless device may perform master cell group link failure recovery using the second wireless link based at least in part on the link failure for the first wireless link.

Abstract: A network device or component such as an access node (AN) can operate to provide a request to obtain a network slice of a network slice as a service (NSaaS) to provide a communication service on the network slice for an end-user device. In response to obtaining the network slice, a network slice customer (NSC) Service identity (ID) associated with the network slice can be determined and provided for a communication service for an application by the end-user device or user equipment (UE). The request can be processed at a network slice provider (NSP) component, in which the network slice can be assigned to the NSC in response to the request by the NSC. The NSP further provides a user equipment (UE) route selection policy (URSP) comprising a traffic descriptor that includes the NSC Service ID to the NSC.

Abstract: Peer devices may wirelessly communicate with each other over a bidirectional sidelink logical channel (LCH) through an established bidirectional sidelink radio bearer. An initiating device of the peer devices may dynamically select a logical channel ID for establishing a fully bidirectional or semi-bidirectional SLRB. At least two alternative sidelink radio resource control (PC5-RRC) procedures may ensure the SLRB parameters are configured correctly in the established logical channel. The procedures also allow the network to configure a limited SLRB which is used to couple the SLRB configuration in the direction in which limited traffic (e.g. feedback information such as robust header compression feedback and/or status reports) is transmitted.

Abstract: This disclosure relates to techniques for supporting cell set based mobility. A network may provide configuration information to a wireless device, relating to a current cell and possibly to one or more other cells in one or more cell sets. The wireless device and network may take various measurements. In response to the measurements and the configuration information, the wireless device may perform a cell change to one of the other cells.

Abstract: Re-connecting to a first radio access network (RAN) of a first radio access technology (RAT) may include initially connecting to the first RAN. A connection associated with a voice call may then be connected that includes connecting to a RAN of a second RAT. In response to the voice call connecting to the second RAN, information for both a frequency and a cell associated with connecting to the first RAN may be stored. An end to the voice call may be identified. In response to determining that the voice call has ended, a timer may be generated at the UE that comprises a specified time period and the timer and the information stored for both the frequency and the cell associated with connecting to the first RAN may be utilized to re-connect to the first RAN.

Abstract: Apparatuses, systems, and methods for a wireless device to perform a method including a user equipment device (UE) receiving from a network entity, a configuration message, wherein the configuration message includes a parameter specifying out-of-order delivery of data units from lower layers to upper layers of a protocol stack implemented on the UE, configuring a radio link control (RLC) layer of a protocol stack for out-of-order delivery based on the received configuration message, and notifying the network entity of the configuration of the RLC layer.

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: Apparatuses, systems, and methods for a wireless device to perform enhanced duplication handling and/or failure handling procedures with a network, including one or more base station. The wireless device may connect to a network using multiple paths. The wireless device may autonomously determine whether to duplicate one or more transmissions to the network on the multiple paths. In the event of a radio link control failure associated with one bearer, the wireless device may suspend transmission of the failed bearer while continuing to use one or more other bearers for transmission.

Abstract: This disclosure relates to performing cell re-selection while in an inactive state in a cellular communication system. A wireless device may establish a radio resource control connection with a cellular base station. The wireless device may receive an indication to enter a radio resource control inactive state. The wireless device may perform cell re-selection while in the radio resource control inactive state. Cells that are in the current radio access network notification area of the wireless device may be prioritized over cells that are not in the current radio access network notification area of the wireless device when performing cell re-selection while in the radio resource control inactive state.
