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: Certain aspects of the subject matter described in this disclosure can be implemented in a method for wireless communication by a user equipment (UE). The method generally includes registering with a first public land mobile network (PLMN) of a first network operator in response to detection of an interruption event associated with a second PLMN of a second network operator; determining that the interruption event has ended; and taking one or more actions to communicate with the second PLMN in response to the ending of the interruption event, wherein taking the one or more actions to communicate with the second PLMN is based on a constraint associated with access attempts to the second PLMN.

Abstract: Method and apparatus for blocking session management procedures for a network slice during an NSSAA procedure. The apparatus receives a network slice-specific authentication command for a network slice that is currently allowed. The apparatus determines that the network slice is being authenticated based on the received network slice-specific authentication command. The apparatus blocks session management procedures associated with the network slice based on the determination that the network slice is being authenticated.

Abstract: Methods, systems, and devices for wireless communications are described to improve support for broadcast systems. In some wireless communications systems, such as broadcast systems for a multimedia broadcast/multicast service (MBMS), an inter-site distance between transmitters or between a transmitter and a receiver may be relatively large compared to an inter-site distance for other scenarios of a wireless communication system (for example, cellular data or talk scenarios). A transmitter in a broadcast system may adjust one or more characteristics of resources in a frame, such as the subframe structure, slot structure, or symbol structure, in carriers dedicated for MBMS resource transmissions. For instance, the transmitter may adjust durations of one or more symbols in a frame.

Abstract: Certain aspects of the present disclosure provide techniques for performing a public land mobile network (PLMN) selection procedure based on allowed PLMN(s) in a particular country of a user equipment (UE). An example method generally includes determining a country in which the UE is located, creating a list of available PLMNs, that are allowed to be selected in the country in which the UE is located, for access to a non-terrestrial network (NTN), and performing a PLMN selection procedure for access to the NTN based on the list of available PLMNs and the country in which the UE is located.

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.

In some aspects, a method of wireless communication performed by a user equipment includes receiving, from a base station, a first indication of one or more paging carriers, the first indication indicating for a paging carrier of the one or more paging carriers, a coverage level supported by the paging carrier; and receiving, from the base station, a paging message via the paging carrier based on a match between the coverage level supported by the paging carrier and a coverage level of the user equipment.

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: Protected configuration data may be sent to user equipment subscribed to a first wireless communication network by a second wireless communication network with which the user equipment is registered. The first wireless communication network may protect the configuration data based on at least one first key when sending the data to the second wireless communication network. The second wireless communication network may send the configuration data to user equipment in messages protected by at least one second key. User equipment receives the message from the second wireless communication network, extracts the configuration data using the at least one second key, determines whether the configuration data has been altered at least in part based on the at least one first key, and applies the configuration data if the configuration data has not been altered. The protected configuration data may be sent in an information element of a control plane message.

Abstract: The present disclosure relates to a user equipment (UE) dynamically adjusting a non-access stratum (NAS) timer. Specifically, the UE may determine operation in a wideband and support of an extended coverage (EC) restriction. The UE may further identify a duration of a non-access stratum (NAS) timer based on determining operation in the wideband and the EC restriction. The UE may further transmit an access request message to a network entity to trigger a mobility management procedure. The UE may further receive an acceptance message from the network entity indicating an unrestricted or restricted status of the EC restriction. The UE may further apply the duration to the NAS timer based on the acceptance message indicating the unrestricted or restricted status of the EC restriction received from the network entity or a history of EC restrictions of a public land mobile network (PLMN) in a defined geographic area.

Abstract: Enabling Ethernet Header Compression (EHC) for use with data sent within a Non-Access Stratum (NAS) control plane of a wireless communication network. In one aspect, a wireless communication device sends a signal to a wireless communication network indicating the device supports EHC for data transfer over a control plane. The device obtains a response from the wireless communication network indicating the wireless communication network supports EHC for data transfer over the control plane. The device then sends an Ethernet packet compressed using EHC to the wireless communication network over the control plane. The wireless communication device may be configured to send a request to the wireless communication network to use EHC before sending the Ethernet packet compressed using EHC. The device then sends the compressed Ethernet packet only if the request is granted. In another aspects, complementary EHC features are provided within a network component of the wireless communication network.

The method generally includes obtaining, for one or more networks, network slicing information indicating one or more slice identifiers supported in the one or more networks, deriving a list of one or more preferred networks based, at least in part, on the network slicing information, and selecting a network to register with from the list of one or more preferred networks.

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: Methods, systems, and devices for wireless communications are described. A base station may configure an outer coded block which a user equipment (UE) may implement to recover an unsuccessfully decoded transmission. The base station may send, to the UE, downlink control information (DCI) indicating an outer coding scheme for the group of data blocks (e.g., a first data block and a second data block). The UE may monitor for the data blocks and the outer coded block. The UE may decode the data blocks based on the outer coded block and the outer coding scheme. In some examples, the outer code block may be made up of a combination of the first and second data blocks. The UE may use the combination of the outer coded block and one of the data blocks to decode an unsuccessfully decode data block.

Abstract: Disclosed are techniques for wireless communication using satellite access to a wireless network, where a wireless cell supported by a satellite is moving or temporarily fixed. In an aspect, a radio access network (RAN) entity or a user equipment (UE) provides, to a core network entity, an enhanced cell global identifier (CGI), where the enhanced CGI includes at least one field representing a location of the UE. Based on the enhanced CGI, the core network entity determines a location of the UE, and may provide a service to the UE based on the location. A core network may also provide an enhanced CGI to a RAN, e.g., to support wireless emergency alerting to UEs.
