Abstract: A user equipment (UE) performs a public land mobile network (PLMN) scan for a higher priority PLMN, and reports a list of candidates PLMNs based on the scan. An identity of a first one of the candidate PLMNs includes a shared mobile country code (MCC). The shared MCC has a value between 900 and 999 and is also used for performing access with satellite technology. The UE selects the first one of the candidate PLMNs from among the list of candidate PLMNs. Each of the candidate PLMNs has either a mobile country code (MCC) the same as an identity of a serving PLMN or the shared MCC, when the identity of the serving PLMN does not comprise the shared MCC. The selecting is based on the first one of the candidate PLMNs having a higher priority than the serving PLMN.

Abstract: Aspects of the present disclosure relate to wireless communications, and more particularly, to techniques for improving data delivery in dual subscriber identity module (dual SIM) scenarios where a single radio resource is shared. One example method by a user-equipment (UE) generally includes sending a protocol data unit (PDU) session establishment request message to a network entity of a first radio access network (RAN) and including, in the PDU session establishment request message, an indication of how the UE wants the network entity to handle mobile terminated (MT) service delivery after the UE leaves the first RAN via a graceful leave procedure.

Abstract: Certain aspects of the present disclosure provide techniques for periodically switching off geosynchronous cells. A method that may be performed by a user equipment (UE) includes receiving an indication that a non-terrestrial network (NTN) cell will stop broadcasting synchronization signals (SS) during a period of time; and performing one or more actions during the period of time based on the indication.

Abstract: Aspects are provided which allow an MA PDU session to establish over two 3GPP accesses respectively via different PLMNs associated with respective USIMs of a MUSIM device. During registration, the MUSIM UE may transmit a registration request to a base station of a first PLMN indicating a UE capability for a MA PDU session associated with a MUSIM device. The MA PDU session includes a plurality of PDU sessions associated with a single access type. Afterwards, the UE may transmit a PDU session establishment request for a first PDU session of the PDU sessions in the first PLMN and for a second PDU session of the PDU sessions in a second PLMN, where the first PLMN is associated with a first USIM of the UE, and the second PLMN is associated with a second USIM of the UE. Consequently, MA PDU sessions associated with MUSIM devices may be established.

Abstract: Method and devices for wireless communications are described. A user equipment, UE, establishes (1005) a first wireless connection with a network via a public land mobile network, PLMN. The UE selects (1010) a standalone non-public network, SNPN, for establishment of a dual wireless connection between the UE and the network from a set of SNPNs associated with dual access of the network. In some examples, the UE selects the SNPN from one or more prioritized lists that include or indicate SNPNs that support dual access of the network via the PLMN and one of the SNPNs. The UE establishes (1015) a second wireless connection with the network via the selected SNPN to establish the dual wireless connection with the first network.

Abstract: This disclosure provides systems, apparatus, methods, and computer-readable media that support radio resource control (RRC) state selection for multicast service reception. A user equipment (UE) may subscribe to a multicast service while in an RRC connected state and may thereafter transition to an RRC inactive state. Subsequently, a network entity may transmit an indication of whether the UE is to remain in the RRC inactive state to receive a multicast transmission associated with the multicast service or whether the UE is to transition to the RRC connected state to receive the multicast transmission. In some aspects, the indication may enable some UEs may remain in an RRC inactive state to receive a multicast transmission (which may reduce power consumption), while other UEs may transition to an RRC connected state to receive the same multicast transmission (which may increase communication reliability). Other aspects and features are also claimed and described.

Abstract: An apparatus for wireless communication includes a memory and a processor coupled to the memory. The processor is configured to send a data session establishment request to establish a data session with a network device using a wireless communication network. The data session establishment request has a first field to indicate a requested network slice for the data session. The processor is further to receive an indication of a granted network slice for the data session and to receive an indication of a back-off timer value from the network device. The processor is further configured, after expiration of a back-off timer based on the back-off timer value, to send a first message associated with the granted network slice and to send a second message having a second field corresponding to the first field of the data session establishment request.

Abstract: Certain aspects of the present disclosure provide a method of wireless communication by a user equipment (UE). The method generally includes performing a mobility procedure to establish a connection in a target radio access technology (RAT) while maintaining a context established in a source RAT, wherein one of the source RAT or target RAT is a terrestrial network (TN) RAT and the other is a non-terrestrial network (NTN) RAT and sending a tracking area update (TAU) request after establishing the connection in the target RAT.

Abstract: A method for wireless communication at a user equipment (UE) and related apparatus are provided. In the method, the UE transmits, for a network entity, a registration request including a first capability indication of a capability for a first encapsulation method of a data packet over a control plane, and receives, from the network entity, a registration response including a second capability indication of the capability for the first encapsulation method. The UE further communicates, based on the first capability indication and the second capability indication, the data packet over the control plane using one of the first encapsulation method or a second encapsulation method of the data packet over the control plane different from the first encapsulation method.

Abstract: A method of wireless communication performs a public land mobile network (PLMN) search for a higher priority PLMN. The PLMN search includes a candidate PLMN having a different mobile country code (MCC) than a serving PLMN. The method switches to the higher priority PLMN when the PLMN search locates the higher priority PLMN. A method determines whether a user equipment (UE) has transitioned between an international area and a national area. The method triggers PLMN selection in response to the UE having transitioned between the international area and the national area.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may transmit a registration request message. The UE may receive a registration pending message. The UE may enter a registration pending state. The UE may transmit a registration resume message based at least in part on one or more parameters associated with the registration pending message. The UE may receive a registration accept message or a registration reject message. Numerous other aspects are described.

Abstract: Techniques are described to support call routing and location for a user equipment (UE) with satellite wireless access to a serving PLMN. The UE sends a Session Initiation Protocol (SIP) INVITE message to a network node, such as a P-CSCF, that includes an indication of satellite access for the UE. In response the network node sends a request to another network node for a cell ID for a fixed cell in which the UE is located. The fixed cell can be independent of satellite radio cells for the serving PLMN. The network node may receive the cell ID for the fixed cell and sends the SIP INVITE message to another network node (e.g., an E-CSCF or LRF) with the cell ID for the fixed cell. The other network node may use the cell ID to route the SIP INVITE message or obtain an approximate location of the UE.

Abstract: A user equipment (UE) selects or reselects a target cell of a non-terrestrial network or resumes connectivity with the target cell after a satellite handover for a permanently fixed low Earth orbit (LEO) cell. The target cell is a serving or non-serving cell. The UE determines a cell type of the target cell. The cell type may be a LEO cell type, a geostationary Earth orbit (GEO) cell type, a moving cell type, a fixed cell type, a temporarily fixed LEO cell type, or a permanently fixed LEO cell type. The UE completes selection or reselection of the target cell or completes the connectivity with the target cell, based on the cell type.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may receive broadcast information from a base station indicating a numerology or a reference signal (RS) pattern to be used in broadcast or multicast transmissions (e.g., a physical multicast channel (PMCH)). The UE may identify a modulation and coding scheme (MCS) associated with the broadcast or multicast transmission and may determine a transport block size (TBS) based on the MCS and at least one of the numerology or the RS pattern. For instance, a UE may determine TBS for numerologies associated with a single symbol that spans multiple subframes differently from that of other numerologies. Additionally or alternatively, a UE may determine TBS for sparse RS patterns differently from that of other RS patterns. The UE may then perform communication with the base station via the broadcast or multicast transmissions in accordance with the TBS.

Abstract: Methods, systems, and devices for wireless communications are described. A system may support a delayed response to a paging message to improve paging throughput. A user equipment (UE) may receive, at a first layer of the UE and from a second layer of the UE, a first signal indicating a delay associated with a paging response for the UE. The UE may operate in a first state based on the first signal. The first state may be associated with a pending paging response and a reset of one or more operation parameters of the UE to support the delay associated with the paging response. The UE may transition, after the delay based on satisfaction of one or more paging response conditions, from the first state to a second state associated with initiation of the paging response. The UE may respond to a paging request after transitioning to the second state.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive broadcast information associated with one or more services provided by a network. The UE may obtain a location for accessing service information that describes the one or more services based at least in part on the broadcast information. The CE may access the service information based at least in part on the location. Numerous other aspects are described.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may receive, from a network, a procedure rejection message for non-cellular access at a non-access stratum (NAS) layer, and provide a first congestion indication from the NAS layer to lower layers for non-cellular access based at least in part on the receiving the procedure rejection message. The UE may refrain, at the lower layers, from initiating establishment of a signaling connection based at least in part on the first congestion indication. Numerous other aspects are provided.

Abstract: A UE may include IoT NTN device, and the UE may acquire the GNSS location to perform the time/frequency pre-compensation. A NAS layer of the UE may initiate a connection request procedure based on the GNSS fix procedure at one or more lower layer of the UE. A network may transmit a paging request to the UE, and manage a paging response timer based on the GNSS fix procedure at the UE.

Abstract: Methods, systems, and devices for wireless communications are described. A user equipment (UE) may monitor one or more first conditions pertaining to non-cellular communications between the UE and a non-cellular network while the UE is operating in a dual networking mode for steering, switching, or splitting traffic (e.g., an access traffic steering, switching, and splitting (ATSSS) mode) between the non-cellular network and a cellular network. The UE may predict an availability status of at least the non-cellular network based on at least one of the one or more first conditions. In some cases, the UE may determine whether to change dual networking modes based on the availability status and may communicate in accordance with the same or a different dual networking mode using at least one of the cellular network, the non-cellular network, or a combination thereof based on the prediction.
