A wireless device receives, from a mobility management function, an indication that a network slice is pending. The wireless device sends, to the mobility management function based on the network slice being pending, an indication for removal of the network slice.

Network slice

A wireless device of a vehicle sends, to an access and mobility function (AMF), a registration request message requesting registration of the wireless device, the registration request message comprising a wireless device identity of the wireless device. The wireless device sends, to a SMF, a message requesting establishment of a packet data unit (PDU) session of the wireless device, wherein the message comprises a vehicle identity of the vehicle, wherein the vehicle identity is different from the wireless device identity. The wireless device receives, from the SMF, a response message for establishment of the PDU session.

Policy and charging control for a vehicle terminal

A first wireless device transmits, to a second wireless device one or more RRC messages indicating a time duration of a latency bound for reporting a CSI of first and second carriers. An expiration of the time duration is associated with a cancellation of reporting of the CSI and the latency bound is associated with one or more resource pools of each carrier. The first device transmits, to the second wireless device and via the first carrier, respective first and second SCIs requesting CSIs of each carrier, and receives respective first and second MAC CEs comprising the CSIs of each carrier before expiration of the time duration after the transmitting the SCIs.

Channel state information report latency bound

A visited session management function of a visited public land mobile network (PLMN) sends, to a home session management function of a home PLMN of a wireless device, a request of the wireless device for a packet data unit, PDU, session in a network slice. The visited session management function receives, from the home session management function, a cause value indicating that a network slice quota of the home PLMN has been reached for a number of PDU sessions for the network slice.

Control of network slice

A wireless device receives, from a base station, a medium access control (MAC) control element (CE) indicating a layer 1 or layer 2 triggered mobility (LTM) cell switch from a first cell to a second cell and a resource of the second cell for a transmission, by the wireless device, of a random access preamble.

Resource for layer 1 or layer 2 triggered mobility

A wireless device receives a first configured grant (CG) configuration, associated with a first CG index, comprising one or more parameters indicating to disable: monitoring for retransmissions corresponding to the first CG configuration; and starting a discontinuous reception (DRX) hybrid automatic repeat request (HARQ) round trip time (RTT) timer for a HARQ process associated with a transport block (TB) transmitted via a CG resource indicated by the first CG configuration. The wireless device receives a second CG configuration not associated with the first CG index. Based on the first CG configuration, the wireless device does not start a first DRX HARQ RTT timer for a first HARQ process, and based on the second CG configuration, the wireless device starts a second DRX HARQ RTT timer for a second HARQ process.

Handling on retransmission for extended reality

A wireless device transmits, to a base station, a measurement report message and receives, from the base station, a first radio resource control (RRC) reconfiguration message comprising a layer 1/layer 2 triggered mobility (LTM) configuration comprising an LTM candidate configuration of a candidate cell for an LTM, an identifier of the LTM candidate configuration, and a cell identifier of the candidate cell. The wireless device transmits, after receiving the first RRC reconfiguration message and to the base station, an RRC reconfiguration complete message and transmits, to the base station, a layer 1 measurement report and receives, from the base station, a second RRC reconfiguration message indicating to release the LTM candidate configuration. A cancelling of the LTM is indicated by an LTM cancel message comprising the identifier of the candidate cell and a cause value indicating a reason for the cancelling of the LTM of the candidate cell.

Layer 1/layer 2 triggered mobility cancelation initiated by target base station

A method can include transmitting, by a wireless device, a capability message comprising a field indicating a time gap of the wireless device to complete a procedure of layer 1 or layer 2 triggered mobility (LTM). The method can also include receiving, in a time interval, a medium access control control element (MAC CE) indicating cell switch to a candidate cell of LTM. The method can further include transmitting, via the candidate cell and a time resource, an uplink transmission, wherein the time resource is after the time gap plus an offset from the time interval.

Timing advance for mobility

A wireless device receives a radio resource control (RRC) message indicating a first resource pool of a sidelink (SL) communication. The wireless device determines, from a candidate resource set in the first resource pool, a SL grant indicating resources for one or more SL transmissions of the SL communication. The wireless device receives, by a medium access control (MAC) layer from a physical layer of the wireless device, an indication of SL listen before talk (LBT) failure of a first resource of the resources indicated in the SL grant. Based on the indication, the wireless device selects, for the first resource, a second resource from the first resource pool excluding resources associated with SL LBT failure. The wireless device transmits, via the second resource, the one or more SL transmissions of the SL communication.

A wireless device receives a layer 1 or layer 2 triggered mobility (LTM) cell switch command. The LTM cell switch command comprises a configuration index indicating a cell for an LTM procedure and does not comprise a timing adjustment value for a primary timing advance group (PTAG) of the cell. In response to receiving the LTM cell switch command with no timing adjustment value, the wireless device starts a time alignment timer associated with the PTAG after measuring a timing advance of the cell.

An access and mobility management function (AMF) receives, from a base station, a non-access stratum (NAS) request message of a wireless device comprising one or more single network slice selection assistance information(s) (S-NSSAIs) corresponding to one or more network slices. The AMF determines to perform network slice specific authentication and authorization (NSSAA) for a first network slice of the one or more network slices. The AMF sends, to the base station, based on the determining, an N2 setup message comprising an indication that the first network slice is pending.

Network slice specific authentication and authorization

A user plane function (UPF) receives, from a control plane function (CPF), a request to establish a layer 2 tunneling protocol (L2TP) tunnel for a first protocol data unit (PDU) session of a wireless device. The UPF sends, to the CPF, a message comprising a tunnel failure cause for the establishment of the L2TP tunnel for the first PDU session. The message indicating at least one of a L2TP tunnel failure of the L2TP tunnel, or a L2TP session failure associated with the L2TP tunnel.

Tunnel failure signaling procedures

A wireless device receives, from a first network, one or more messages comprising an authentication and/or authorization (AA) status of the wireless device indicating whether the wireless device is authenticated and/or authorized for an aerial service, and a parameter indicating that an interface between the first network and a second network is not supported. The wireless device sends, to a network function of the second network, a message, wherein the message comprises the AA status based on the parameter indicating that there is no interface.

Aerial service

A first wireless device transmits, to a second wireless device, a discovery message comprising a non-public network (NPN) identifier of an NPN to which the first wireless device can provide access.

Relay node selection

A second base station sends to a first base station, a request for a context of a wireless device, wherein the request comprises assistance information for a small data transmission (SDT) procedure of the wireless device. The assistance information indicates whether single data associated with the SDT procedure is expected, or more than single data associated with the SDT procedure is expected.
