Abstract: Techniques for identity-based message integrity protection and verification between a user equipment (UE) and a wireless network entity, include use of signatures derived from identity-based keys. To protect against attacks from rogue network entities before activation of a security context with a network entity, the UE verifies integrity of messages by checking a signature using an identity-based public key PKID derived by the UE based on (i) an identity value (ID) of the network entity and (ii) a separate public key PKPKG of a private key generator (PKG) server. The network entity generates signatures for messages using an identity-based private key SKID obtained from the PKG server, which generates the identity-based private key SKID using (i) the ID value of the network entity and (ii) a private key SKPKG that is known only by the PKG server and corresponds to the public key PKPKG.

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: Embodiments described herein relate to credential wrapping for secure transfer of electronic SIMs (eSIMs) between wireless devices. Transfer of an eSIM from a source device to a target device includes re-encryption of sensitive eSIM data, e.g., eSIM encryption keys, financial transaction credentials, transit authority credentials, and the like, using new encryption keys that include ephemeral elements applicable to a single, particular transfer session between the source device and the target device. The sensitive eSIM data encrypted with a symmetric key (Ks) is re-wrapped with a new header that includes a version of Ks encrypted with a new key encryption key (KEK) and information to derive KEK by the target device. The re-encrypted sensitive SIM data is formatted with additional eSIM data into a new bound profile package (BPP) to transfer the eSIM from the source device to the target device.

Abstract: Systems and methods for facilitating transfer of an eSIM subscription from a source device to a target device. In one embodiment, a source device includes a transceiver and a processor system. The processor system includes an eUICC configured to store an eSIM associated with an eSIM subscription. The processor system is configured to transmit, via the transceiver and to an eSIM subscription manager server, a request for an eSIM subscription transfer activation code; receive, via the transceiver and at least partly in response to the request, a server nonce; generate a signed payload using the server nonce and source device information; transmit, via the transceiver and to the eSIM subscription manager server, the signed payload; receive, via the transceiver and in response to transmitting the signed payload, the eSIM subscription transfer activation code; and provide the eSIM subscription transfer activation code to the target device or a user thereof.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for utilizing a flexible slot indicator in wireless communication. A base station (BS) may establish communication with a first user equipment device (UE). The BS may determine a transmission direction for each of a plurality of symbols included in one or more slots. The BS may transmit a slot format indicator (SFI) to the UE. The SFI may indicate the transmission direction for each of the plurality of symbols included in one or more slots. The BS and the UE may perform communication during the one or more slots according to the determined transmission direction.

Abstract: A mobile network operator (MNO) uses a provisioning server to update or install profile content in a profile or electronic subscriber identity module (eSIM). In an exemplary embodiment, the profile is present on a secure element such as an embedded universal integrated circuit card (eUICC) in a wireless device. One or more MNOs use the provisioning server to perform profile content management on profiles in the eUICC. In some embodiments, an MNO has a trust relationship with the provisioning server. In some other embodiments, the MNO does not have a trust relationship with the provisioning server and protects payload targeted for an MNO-associated profile using an over the air (OTA) key.

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.
