Abstract: A user equipment (UE) may receive a list of Public Land Mobile Networks (PLMNs) that support a given network slice in a given country, different from a home country of a home PLMN of the UE. When roaming in the given country, UE may access a PLMN of the list if the given network slice is desired. The list may be provided by the home PLMN: while the UE is in the home country; or via a visited PLMN while the UE is in the given country. The list may be received in response to a UE-initiated request, or pushed to the UE by the home PLMN. A validity timer period received with the list may indicate a duration of validity of the list. In an alternative scenario, the UE may receive the list from an entitlement server, e.g., one belonging to a visited PLMN.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for enhancement of multi-SIM devices, such as UE 106. A network may increase paging retries for known MU-SIM devices, e.g., based on an indication of capabilities from a MU-SIM device. The indication may be via a NAS registration request, an RRC capability procedure, and/or an RRC UE assistance procedure. Additionally, a network may include an indication of a paging priority to the UE. The UE may then determine a response to the page based, at least in part, on the indicated priority. Further, the UE may indicate a tune-away to the network. The indication of the tune-away may include a cause and/or duration for the tune-away and may be provided at an RRC level or a network access stratum (NAS) level.

Abstract: A device, system and method for a user equipment (UE) to opportunistically utilize the wireless capabilities of a paired device. The UE is configured to establish a first cellular network connection based on a first subscription, a second cellular network connection based on a second subscription and a connection to a further UE based on a short-range communication protocol. The UE identifies a predetermined condition and transmits an indication to the further UE based on the predetermined condition. The further UE establishes a further cellular network connection in response to the indication and the further cellular network connection is based on one of the first subscription or the second subscription. The UE then declares no service for one of the first cellular network connection or the second cellular network connection based on the further cellular network connection.

Abstract: Apparatuses, systems, and methods for a dual subscriber identity module (SIM) dual standby (DSDS) capable user equipment (UE) devices to perform data operations with a first SIM that is not capable of or preferred for packet switched (PS) services and a second SIM that is capable of or preferred for PS services. A timer may be initiated upon radio frequency (RF) chain handover from the first SIM to the second SIM, whereupon a first connection associated with the first SIM is maintained in an idle state while the timer is running. Upon expiration of the timer, the UE may determine whether to send a scheduling request to maintain or release the first connection. The timer may be utilized when a call is dropped over the first connection, to increase the likelihood of successfully receiving a callback. The timer may be shortened in duration to reduce reception of spam messaging.

Abstract: A device is configured to establish a first roaming network connection to a first roaming network and a second roaming network connection to a second roaming network. The first roaming network has a higher priority than the second roaming network, the second roaming network configured to support a first radio access technology (RAT) and a second RAT, the first RAT having a higher priority than the second RAT. When a current network connection is the second roaming network connection, determining a current RAT used for the second roaming network connection. When the current RAT is the first RAT, determining between an active use state and a non-active use state. When the device is in the active use state, deactivating a capability to reselect to the first roaming network.

Abstract: A wireless communication device (UE) conducting wireless communications according to a specified radio access technology (RAT) in a first communications band belonging to a first network may be required to switch to a different communications band due to network restrictions and/or radio link failure. The UE may therefore perform a system scan identifying other communications bands associated with the first RAT and available at the present location of the UE. The UE may identify whether the other communications bands include preferred communications bands belonging to the first network, support a service associated with the wireless communications of the UE, and have an energy level higher than a specified threshold. If one or more preferred communications bands are present, the UE may switch communications from the first communications band to one of the preferred communications bands, even if it doesn't have the highest energy level among all the other communications bands.

Abstract: A wireless device may connect, using a first subscriber identity module (SIM), to a first base station according to a first radio access technology (RAT) and a second base station according to a second RAT. The wireless device may also connect, using a second SIM, to a third base station according to the first RAT. The wireless device may, in response to the second SIM performing a call according to the first RAT, disable the first RAT for the first SIM and perform, using the first SIM, data communication according to the second RAT while the call is performed using the second SIM.

Abstract: This disclosure relates to methods and devices for mitigating overheating in a user equipment device (UE). The UE is configured to communicate over each of LTE and 5G NR and may be configured to communicate through 5G NR over each of a Sub-6 GHz and a millimeter Wave (mmW) frequency band. The UE is configured to establish an ENDC connection with an enB and one or more gNBs. The UE implements intelligent transmission modification and cell measurement adjustments to mitigate overheating and reduce battery drain.

Abstract: A user equipment (UE) that is registered to a stand-alone non-public network (SNPN) can also access services on a public land mobile network (PLMN). The UE accesses the PLMN by transmitting a first signal to a data network, receiving a second signal from the data network in response to the first signal, wherein the second signal identifies a PLMN that is configured to be accessed by the UE via the data network and transmitting a session initiation protocol (SIP) registration request to the PLMN via the data network.
