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 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.

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.

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: A PDCP layer of a first transmitting device determines a transmission failure of at least one PDCP SDU, wherein a plurality of PDCP SDUs, comprising a data unit of a data flow, comprise the at least one PDCP SDU. 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.

Abstract: A method may include sending, by a wireless device to an access and mobility management function (AMF) via a first cell, a first registration request message requesting a network slice. The method may also include receiving, by the wireless device from the AMF, a first registration accept message. The message may include a network slice selection assistance information (NSSAI) indicating the network slice and may also include an indication that the network slice is rejected in a tracking area of a registration area. The method may further include, upon a cell change to a second cell, sending, by the wireless device to the AMF via the second cell and based on the indication, a second registration request message requesting the network slice. The method may additionally include receiving, by the wireless device from the AMF, a second registration accept message accepting the network slice.

Abstract: A method may include starting, by a wireless device, a small data transmission, SDT, failure detection timer based on initiating an SDT procedure. The method may also include stopping, by the wireless device, the SDT failure detection timer based on non-SDT data arriving during the SDT procedure. The stopping the SDT failure detection timer may be based on transmitting a radio resource control, RRC, message for the non-SDT data arriving during the SDT procedure.

The SMF sends, to the wireless device, an indication that the PDU session is to be established as the always-on PDU session.
