Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: 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.
