Abstract: An access and mobility management function receives, from a session management function, a request to set up a communication with a wireless device for transmitting downlink data. The access and mobility management function sends, based on the request, to the base station, a first paging message for a closed access group (CAG) wireless device that is allowed to access CAG cells. The first paging message indicates transitioning the CAG wireless device from an idle state to a connected state. The first paging message comprises a parameter indicating whether the wireless device is allowed to access non-CAG cells.

Abstract: A wireless device may communicate with a base station via a cell. A cell may be selected for wireless communications based on having a configuration that is capable of serving certain wireless resources associated with a wireless device. A wireless device may select a cell that comprises a communication link supporting certain wireless resources that may be required for use by the wireless device.

Abstract: A base station central unit receives, from a base station distributed unit, configuration parameters of at least one periodic radio resource for packet transmissions of a wireless device in a radio resource control (RRC) inactive state or RRC idle state. The base station central unit sends, to the base station distributed unit, a wireless device context release message comprising an RRC release message and an indication that the base station distributed unit maintains the at least one periodic radio resource after the wireless device transitions to the RRC idle state or the RRC inactive state. The base station central unit receives, via the base station distributed unit, data from the wireless device while the wireless device is in the RRC inactive state or the RRC idle state.

Abstract: A policy and charging control function (PCF) receives, from a session management function (SMF), a request for policy information of a wireless device, the request comprising a parameter of a time sensitive networking (TSN) bridge, wherein the parameter comprises port information of the TSN bridge. The PCF sends, to the SMF, a response to the request, the response comprising the policy information of the wireless device.

Abstract: A base station may communicate with other base stations for handover decisions. Information about energy consumption of other base stations may be used by the base station for efficient handover decisions. Predictions of energy consumption may be exchanged before making a handover decision so that handover decisions may be based on energy usage.

Abstract: A base station may communicate with one or more other base stations. A first base station may hand over one or more wireless devices served by its cell to a second base station (e.g., a neighboring base station), for example, to save overall energy consumption in the network. Feedback information (e.g., one or more messages) associated with performance of the second base station after the handover may be provided by the second base station to the first base station help further decision-making related to handing over other wireless device(s).

Abstract: A base station central unit receives, from a wireless device, one or more radio resource control (RRC) messages comprising a resume identity of the wireless device. The base station central unit sends, to a base station distributed unit, a message indicating release of a configured uplink grant configuration, of a cell of the base station distributed unit, for an RRC inactive state or an RRC idle state of the wireless device.

Abstract: An access and mobility management function (AMF) receives from a first wireless device a non-access stratum (NAS) message comprising an identifier (ID) of a group communication session. The AMF receives from a session management function (SMF) a message comprising a list of one or more second wireless devices associated with the group communication session and a list of one or more packet data unit (PDU) sessions. The AMF determines, based on a state of the one or more second wireless devices, to page the one or more second wireless devices. The AMF receives from the one or more second wireless devices one or more service request messages.

The PDCP layer of the first transmitting device discards, based on the determining, the plurality of PDCP SDUs.

Abstract: A base station transmits, to a wireless device, at least one first radio resource control message comprising configuration parameters for a first session associated with a first session identifier between the wireless device and a user plane function and a second session associated with a second session identifier different from the first session identifier, for packet duplication of the first session, between the wireless device and the user plane function. The base station transmits, to the wireless device, at least one second radio resource control message indicating activation of the packet duplication. Based on the activation of the packet duplication, the base station receives original packets via the first session associated with the user plane function and duplicated packets of the first session via the second session.

Abstract: A method may include multiplexing, by a wireless device, a radio resource control, RRC, message in a medium access control protocol data unit, MAC PDU. The RRC message may indicate arrival of non-small data transmission, SDT, data. The multiplexing may be based on a logical channel prioritization order indicating that the RRC message is higher priority than data of an SDT procedure. The method may also include transmitting, by the wireless device, the MAC PDU.
