Abstract: Apparatuses, systems, and methods for a wireless device to perform substantially concurrent communications with a next generation network node and a legacy network node. The wireless device may be configured to stablish a first wireless link with a first cell according to a RAT, where the first cell operates in a first system bandwidth and establish a second wireless link with a second cell according to a RAT, where the second cell operates in a second system bandwidth. Further, the wireless device may be configured to perform uplink activity for both the first RAT and the second RAT by TDM uplink data for the first RAT and uplink data for the second RAT if uplink activity is scheduled according to both the first RAT and the second RAT.

Abstract: This disclosure relates to techniques, base stations, and user equipment devices (UEs) for performing base station authentication through access stratum signaling transmissions. The UE may operate in idle mode and may receive an authentication message from a base station through the wireless interface while operating in idle mode. The UE may determine whether a signature comprised within the authentication message is valid, and the UE may continue a connection procedure with the base station based on a determination that the signature is valid. If it is determined that the signature is invalid, the UE may designate the base station as a barred base station and may perform cell re-selection. The authentication message may be one of a radio resource control (RRC) connection setup message, a special RRC message, a media access control (MAC) message, or a random access channel (RACH) message comprising a random access response (RAR) message.

Abstract: Techniques are disclosed relating to authenticating a user with a mobile device. In some embodiments, a computing device stores a first signed attestation indicating an ability of the computing device to securely perform a user authentication. The computing device receives a request to store credential information of an identification document issued by an issuing authority to a user for establishing an identity of the user. In response to the request, the computing device sends, to the issuing authority, a request to store the credential information, the sent request including the first signed attestation to indicate an ability to perform a user authentication prior to permitting access to the credential information. In response to an approval of the sent request based on the first signed attestation, the computing device stores the credential information in a secure element of the computing device.

Abstract: Methods and apparatus for user authentication and human intent verification of administrative operations for eSIMs of an eUICC included in a mobile device are disclosed. Certain administrative operations, such as import, modification, and/or export, of an eSIM and/or for an eUICCs firmware can require user authentication and/or human intent verification before execution of the administrative operations are performed or completed by the mobile device. A user of the mobile device provides information to link an external user account to an eSIM upon (or subsequent to) installation on the eUICC. User credentials, such as a user name and password, and/or information generated therefrom, can be used to authenticate the user with an external server. In response to successful user authentication, the administrative operations are performed. Human intent verification can also be performed in conjunction with user authentication to prevent malware from interfering with eSIM and/or eUICC functions of the mobile device.

Abstract: Apparatuses, systems, and methods for a wireless device to detect intermodulation issues and configure a transmission scheme to remedy detected intermodulation issues. The wireless device may perform measurements on a downlink carrier while one uplink carrier is scheduled for the wireless device. The wireless device may also perform measurements on the downlink carrier while two uplink carriers are scheduled for the wireless device. The wireless device may provide information based on those measurements to a serving base station. The base station may determine that an intermodulation issue is occurring at the wireless device based on the information provided, and may configure the wireless device to use a single uplink carrier at a time based at least in part on the intermodulation issue.

Abstract: TDD configuration may be dynamically and/or semi-statically signaled to user equipment devices by a base station. Semi-static TDD configuration may include: an initial portion for downlink transmission; a flexible portion; and a terminal portion for uplink transmission. TDD structure of the flexible portion may be determined later by transmission of dynamic physical layer configuration information such as downlink control information (DCI) and/or slot format indicator (SFI). (The SFI may be included in a group common PDCCH of a slot.) The downlink portion and/or the uplink portion may include subsets whose nominal transmit direction is subject to override by transmission of dynamic physical layer configuration information.

Abstract: Apparatuses, systems, and methods for a wireless device to perform simultaneous uplink activity for multiple RATs in the same carrier using frequency division multiplexing. The wireless device may establish a first wireless link with a first base station according to a first radio access technology (RAT) and a second wireless link with a second base station according to a second RAT. The first base station may provide a first cell operating in a first system bandwidth and the second base station may provide a second cell operating in a second system bandwidth. The wireless device may determine whether the wireless device has uplink activity scheduled according to both the first RAT and the second RAT. If so, the wireless device may perform uplink activity for both the first RAT and the second RAT in the first system bandwidth using frequency division multiplexing.

Abstract: A downlink control information (DCI), such as a blanking DCI (bDCI) message may be transmitted by a base station (e.g., eNB) and received by a mobile device (e.g., UE). The bDCI may indicate that the eNB will not transmit a subsequent DCI to the UE for a duration of time. The UE may be in continuous reception mode or connected discontinuous reception (C-DRX) mode. The UE may therefore determine to enter a sleep state or take other action. The bDCI may specify an explicit blanking duration, or an index indicating a blanking duration from a lookup table, and/or the blanking duration (and/or a blanking duration offset value) may be determined in advance, e.g., semi-statically. When the UE is in C-DRX mode, the UE may be configured such that either the sleep/wake period of the C-DRX mode or the blanking period of the bDCI may take precedence over the other.

Abstract: The embodiments set forth techniques for an embedded Universal Integrated Circuit Card (eUICC) to conditionally require, when performing management operations in association with electronic Subscriber Identity Modules (eSIMs), human-based authentication. The eUICC receives a request to perform a management operation in association with an eSIM. In response, the eUICC determines whether a policy being enforced by the eUICC indicates that a human-based authentication is required prior to performing the management operation. Next, the eUICC causes the mobile device to prompt a user of the mobile device to carry out the human-based authentication. The management operation is then performed or ignored in accordance with results of the human-based authentication.

Abstract: The embodiments set forth techniques for enabling mobile devices to trigger an electronic Subscriber Identity Module (eSIM) provisioning process. In some embodiments, a main operating system (OS) of the mobile device communicates a provisioning command to an embedded Universal Integrated Circuit Card (eUICC) included in the mobile device. In turn, the provisioning command causes the eUICC to establish a secure channel with a provisioning server. The provisioning command can include, for example, a network address (e.g., a uniform resource locator (URL), Internet Protocol (IP) address, etc.) associated with the provisioning server, an indication of a security protocol to be used for the secure channel, and/or other information. Using this information, the eUICC establishes the secure channel with the provisioning server, whereupon the provisioning server can provision the eSIM to the eUICC over the secure channel.
