Abstract: A user equipment (UE) device may make measurements of network-configured frequencies in an idle mode or an inactive mode, and report the measurements to the network during (or after) a connection establishment or a connection resume process. The initiation of measurements may be delayed until a connection is imminent or until an upper layer request. A result timer may be used to ensure that reported measurements are not too old to be of use. A configuration timer may be used to selectively report inter-frequency/RAT cell measurements. The configuration timer may also be used repeatedly in conjunction with intervening backoff periods. A base station of the network may use the measurements to make informed decisions on when and how to configure carrier aggregation or dual connectivity for the UE device.

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 performing unicast sidelink access stratum level connection maintenance. A first wireless device and a second wireless device may establish a unicast sidelink wireless connection. One or both of the first wireless device and the second wireless device may perform access stratum level connection maintenance on the unicast sidelink wireless connection. This may include performing any or all of radio link monitoring, radio resource management, or physical layer based link quality detection. The access stratum and the non-access stratum of each device may also communicate with each other regarding either or both of link quality or link status of the unicast sidelink wireless connection.

Abstract: This disclosure relates to providing in order packet delivery for compressed radio bearers. A wireless device may receive packet data at a packet data convergence protocol layer. A packet reordering timer length to use for the packet data at the packet data convergence protocol layer may be adaptively selected from multiple possible packet reordering timer lengths. The packet data may be processed at the packet data convergence protocol layer using the selected packet reordering timer length. The packet reordering timer length may be selected based at least in part on a robust header compression decompressor state of the packet data convergence protocol layer.

Abstract: A device sets an activity mode for a cellular connection. A method to set the activity mode is performed at a device located with a user that is configured to establish a network connection to a network. The method includes determining a status of the user, the status indicating an activity state or a non-activity state of the user. The method includes, when the status indicates the activity state, activating an activity mode on the device that restricts select types of mobile originating data traffic.

Abstract: A wireless communication device (UE) may identify a data flow type associated with data packets to be wirelessly transmitted by the wireless communication device over a wireless network during uplink communications. The UE may determine, based on the data flow type, whether to perform header compression for the data packets on a default bearer assigned to the wireless communication device and associated with the data flow for wireless communications over the wireless network. The UE may perform packet header compression for data flow types for which the packet header size is at least a specified percentage of the total packet size. Packet header compression on the default bearer may be enabled at all times, in which case the UE may indicate to the network whether the UE supports header compression on the default bearer. Alternately, the UE may trigger header compression on the default bearer based on application requirements.

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.
