A wireless user equipment (UE) device may transmit a random access preamble to a base station, using a physical resource on an uplink signal. After failing to receive an initial transmission of a response message from the base station (BS), the UE device may monitor for one or more retransmissions of the response message. Each of the retransmission may include a corresponding transmission number. As an alternative, each of the retransmissions may be at least partially scrambled using a corresponding Radio Network Temporary Identifier (RNTI). As another alternative, a window for monitoring and RNTI calculation may be extended to include the one or more retransmissions. The successive retransmissions may include the same set of UE-specific payloads, or, a decreasing set of payloads over time as UE devices acknowledge successful receipt of their respective payloads.

Retransmission of MsgB in two-step random access procedure

A user equipment (UE) is connected to a wireless network and operates in a carrier aggregation (CA) state that includes a first connection to a primary cell and a second connection to a secondary cell. The UE determines a beam failure has occurred for one of the first connection or the second connection and initiates a beam failure recovery (BFR) operation. The BFR operation includes transmitting, to the primary cell, a BFR Medium Access Control (MAC) Control Element (CE).

Failure handling for secondary cell

The described embodiments set forth techniques for recovering one or more electronic subscriber identity modules (eSIMs) previously deleted from an embedded universal integrated circuit card (eUICC) of a mobile wireless device. Prior to deletion of an eSIM, the mobile wireless device uploads first eSIM subscription information to a cloud network services server and stores second eSIM subscription information in a secure memory of the eUICC. The mobile wireless device can subsequently download the first eSIM subscription information to verify matching to the second eSIM subscription information stored in the eUICC before displaying an option for recovering the eSIM. The mobile wireless device sends to a mobile network operator (MNO) provisioning server an eSIM recovery request notification that includes at least a portion of the first eSIM subscription information, and the MNO provisioning server provides an eSIM recovery response message indicating approval and a network address to download the eSIM.

Deleted eSIM recovery

The described embodiments set forth techniques for transferring an electronic subscriber identity module (eSIM) with the same integrated circuit card identifier (ICCID) value from a source mobile wireless device to a target mobile wireless device directly with a mobile network operator (MNO) provisioning server. The target mobile wireless device downloads the eSIM from the MNO provisioning server after deletion of the eSIM on the source mobile wireless device and reassignment of the eSIM with the same ICCID value to the target mobile wireless device.

Direct eSIM transfer between wireless devices

This Application sets forth techniques for binding and dynamic provisioning of international mobile equipment identifier (IMEI) values with cellular wireless service profiles, such as subscriber identity modules (SIMs) on physical SIM (pSIM) cards and electronic SIMs (eSIMs) on an embedded universal integrated circuit card (eUICC) of the mobile wireless device. When pSIMs and/or eSIMs change on the mobile wireless device, e.g., based on installation, activation, deactivation, de-installation, etc., IMEI binding logic accounts for the changes and maps IMEI values to pSIMs and/or eSIMs as required. IMEI values can be assigned based on a history of bindings between IMEI values and ICCID values of one or more eSIMS on an eUICC. A most recently used or a newly assigned IMEI value can be associated with an eSIM. Whether to assign an identical IMEI value to multiple eSIMs depends on requirements of associated cellular wireless service subscriptions.

IMEI binding and dynamic IMEI provisioning for wireless devices

A base station is configured to transmit wake-up signals to a user equipment to wake-up the UE to receive a page from the base station. The base station transmits one or more synchronization signals, wherein the synchronization signals correspond to a wake-up signal (WUS) that is to be transmitted to a user equipment (UE) operating in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO) and transmits the WUS to the UE during a WUS occasion, wherein the WUS indicates whether the UE is to utilize an active mode or a sleep mode during the PO.

Transmitting wake-up signals for paging operations

Devices, systems and methods for implementing beam failure management techniques at a user equipment (UE). The UE receives a timing advance command (TAC) from a currently camped cell and initiates a time advance timer (TAT). When the TAT is running the UE is in a first operating state. The first operating state indicates that the UE is in time alignment with the cell. The UE identifies that the TAT has expired. When the TAT is not running the UE is in a second operating state. The second operating state indicates that the UE is not in time alignment with the cell. The UE implements one or more beam failure management techniques based on the UE operating in the second operating state.

Beam failure management for user equipment out of synchronization in the uplink

Embodiments are presented herein of apparatuses, systems, and methods for a C-V2X capable wireless device configured to operate according to a first sidelink mode where communication resources are allocated by a network and a second sidelink mode where communication resources are autonomously allocated by the wireless device. The wireless device detects a change in a coverage scenario associated with the first sidelink mode; performs resource sensing for the second sidelink mode; and based at least in part on detecting the change in the coverage scenario, transmits first communications using the second sidelink mode, wherein resources for transmitting the first communications are allocated based at least in part on the resource sensing.

Dual-mode sidelink operation

This Application sets forth techniques for binding and dynamic provisioning of international mobile equipment identifier (IMEI) values with cellular wireless service profiles, such as subscriber identity modules (SIMS) on physical SIM (pSIM) cards and electronic SIMs (eSIMs) on an embedded universal integrated circuit card (eUICC) of the mobile wireless device. When pSIMs and/or eSIMs change on the mobile wireless device, e.g., based on installation, activation, deactivation, de-installation, etc., IMEI binding logic accounts for the changes and maps IMEI values to pSIMs and/or eSIMs as required. IMEI values can be assigned based on a history of bindings between IMEI values and ICCID values of one or more eSIMS on an eUICC. A most recently used or a newly assigned IMEI value can be associated with an eSIM. Whether to assign an identical IMEI value to multiple eSIMs depends on requirements of associated cellular wireless service subscriptions.

Peer devices may wirelessly communicate with each other over a bidirectional sidelink logical channel (LCH) through an established bidirectional sidelink radio bearer. An initiating device of the peer devices may dynamically select a logical channel ID for establishing a fully bidirectional or semi-bidirectional SLRB. At least two alternative sidelink radio resource control (PC5-RRC) procedures may ensure the SLRB parameters are configured correctly in the established logical channel. The procedures also allow the network to configure a limited SLRB which is used to couple the SLRB configuration in the direction in which limited traffic (e.g. feedback information such as robust header compression feedback and/or status reports) is transmitted.
