Abstract: Systems and methods for small data transmissions (SDTs) between a user equipment (UE) and a network are disclosed herein. In some embodiments, the UE determines whether to perform an SDT procedure by comparing its own mobility state to an SDT mobility state condition provided by the network. The UE may also determine whether to perform the SDT procedure by comparing the size of user plane (UP) data to be sent with the SDT procedure to an SDT mobility-based data amount threshold provided by the network. Upon entering an RRC_INACTIVE state, the UE may start a validity timer relative to any such SDT mobility state condition and/or SDT mobility-based data amount threshold, and invalidate these once the validity timer expires. In some disclosed embodiments, the UE reports its determined mobility state to the network during an SDT procedure so that the network can accordingly select configuration parameters for SDT procedures.

Abstract: Apparatuses, systems, and methods for a wireless device to perform a method including a user equipment device (UE) receiving from a network entity, a configuration message, wherein the configuration message includes a parameter specifying out-of-order delivery of data units from lower layers to upper layers of a protocol stack implemented on the UE, configuring a radio link control (RLC) layer of a protocol stack for out-of-order delivery based on the received configuration message, and notifying the network entity of the configuration of the RLC layer.

Abstract: Various radio resource management techniques may be implemented to reduce in-device coexistence issues and/or interference between a Uu link established between a mobile device (first UE) and a base station (first NB), and a sidelink/PC5 link established between the first UE and another mobile device (second UE), where the second UE is served by a different base station (second NB). The first UE may receive, from the first NB, measurement configuration information that enables/configures the first UE to report to the NB any indication(s) of issues caused by communications between the first UE and the second UE over the PC5 link affecting communications between the first UE and the first NB over the Uu link, and/or communications over the Uu link affecting communications over the PC5 link. The first NB may analyze the feedback from the first UE and may implement mitigation measures to reduce/eliminate any interference and/or in-device-coexistence issues.

Abstract: Apparatuses, systems, and methods for a user equipment device (UE) to perform methods for network assisted side-link resource configuration for unicast and/or multi-cast/groupcast communications in V2X networks. A UE may, after establishing an RRC connection with a base station, transmit, to the base station, V2X connection information. The V2X connection information may include a V2X identifier associated with the UE and a V2X identifier associated with a target UE. The UE may receive, from the base station, a side-link configuration for data transmission with the target UE. The side-link configuration may include a resource allocation defined in time and frequency (e.g., a transmit/receive pool). The UE may communicate with the target UE using the resource allocation included in the side-link configuration.

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: When a user equipment (UE) encounters a radio link failure condition, the UE may transmit a radio link failure report to a network. The report may include information defining the radio link monitoring (RLM) resources of a current RLM configuration. The information may take the form of a resource bitmap or a list of resource identifiers/indices. The network may use the information (and radio resource management measurements) to determine whether the radio link failure occurred due to misconfiguration of RLM resources for the UE. In cases where the network does not provide RLM configuration, the UE may omit the bitmap (or list), or populate the bitmap with all zeros, or populate the bitmap (or list) according to a currently active Transmission Configuration Indication (TCI) state, which is indicated by downlink control information (DCI).

Abstract: This disclosure relates to providing early packet delivery to radio link control. A transport block may be received by a wireless device via wireless communication. The transport block may fail a transport block cyclic redundancy check, but a subset of the code blocks of the transport block may pass code block cyclic redundancy checks. Packet data from the subset of the code blocks that pass code block cyclic redundancy checks may be provided to a radio link control layer of the wireless device, based at least in part on the successful code block cyclic redundancy checks for those code blocks.

Abstract: Systems, apparatus and methods enable layer 2 (L2) relaying optimizations for a remote user equipment (UE) to receive system information (SI) from a relay UE. The relay UE may establish a sidelink communication channel with the remote UE that is in a radio resource control (RRC) idle state, an RRC inactive state, or an out-of-coverage (OOC) state with respect to the base station. The relay UE decodes a relay SI request received through the sidelink communication channel from the first remote UE. The relay SI request indicates requested system information. The Relay UE obtains the requested system information or a subset of the requested system information from a memory device or from the base station and encodes a relay SI response to send to the first remote UE. The relay SI response includes the requested system information or the subset of the requested system information.

Abstract: This disclosure relates to a relay user equipment device (UE) assisting one or more remote UEs in performing a radio access network notification area (RNA) update procedure in a cellular communication system. The relay UE establishes a first relay connection with a first remote device. The first relay connection relays communications between the first remote device and a network. The relay UE transmits a first message to the network to initiate the RNA update procedure for the first remote device, receives an acknowledgment message from the network including updated connection information for the first remote device, and transmits the updated connection information to the first remote device.
