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: 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: Techniques are disclosed relating to downlink control information for wireless communications. In some embodiments, the downlink control information includes code block group information that indicates which code block groups are transmitted and soft buffer handling information that indicates whether to flush previously-determined soft bits that correspond to one or more code block groups.

Abstract: Apparatuses, systems, and methods for generating and utilizing improved initialization vectors (IVs) when performing encryption and authentication in wireless communications. In some scenarios, a wireless communication device may generate one or more pseudorandom multi-bit values, e.g., using a respective plurality of key derivation functions (KDFs). A first portion of each value may be used as a respective key for encryption or authentication of traffic on the user plane or the control plane. A second portion of each value may be used as a nonce value in a respective IV for use with a respective key for encryption or authentication of traffic on the user plane or the control plane. In some scenarios, the nonce values may instead be generated as part of an additional pseudorandom value (e.g., by executing an additional KDF), from which all of the IVs may be drawn.

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: This application sets forth techniques for provisioning electronic subscriber identity modules (eSIMs) to mobile wireless devices that do not include functional bootstrap provisioning profiles to obtain access to a cellular wireless network. Connectivity to a cellular wireless network can be allowed for provisioning one or more eSIMs to a mobile wireless device using hardware device identifiers for authentication and a limited purpose provisioning connection when the cellular wireless network supports provisioning connections without the use of a provisioning profile for access.

Abstract: Techniques are disclosed relating to authenticating a user with a mobile device. In various embodiments, a mobile device receives a request to provision the mobile device with identification information from an identification document issued by an authority to a user for establishing an identity of the user. In response to the received request, the mobile device issues a request for verification information signed by the authority and usable to verify the identification information. The issued request identifies multiple public keys of the mobile device, each having a respective corresponding private key for generating a signature usable to verify the identification information. The mobile device receives and stores the signed verification information, the signed verification information including the plurality of public keys. In some embodiments, the mobile device receives a request provide, at least, a portion of the identification information and selects one of the private keys to generate a signature.

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 establish 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: Techniques are disclosed relating to preemption indicators in the context of multiplexing different services on wireless physical layer frames. In some embodiments, a preemption indication is transmitted to indicate resources used by a preempting transmission. The preemption indication may be used when preemption is enabled, e.g., as indicated by an RRC message. The preemption indication may be common to multiple UEs. The resources used by the preempting transmission may overlap with other transmissions. In various embodiments, the disclosed techniques may facilitate signal preemption, e.g., by a low-latency, high-reliability data service.
