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: This disclosure relates to techniques for performing relay communication by a relay wireless device in a wireless communication system. A relay wireless device may receive bearer configuration information from a network. Based on the bearer configuration information, the UE may establish a bearer with a remote wireless device. The relay wireless device may forward data to/from the remote wireless device using the bearer.

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.

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: A transmitter (e.g. a packet data convergence protocol, PDCP, in the transmitter), which may be a base station for downlink communications or a user equipment device for uplink communications, may control timing of the delivery of duplicate (same) packets to multiple (e.g. two) wireless links (e.g. radio link control links) for transmission to a receiver, based at least on synchronization information received from the receiver. The duplicate packets may be transmitted over the multiple wireless links to the receiver, which may receive the duplicate packets over the multiple wireless links. The receiver may collect and/or generate synchronization information indicative of the timing or latency between the multiple wireless links, based at least on the respective receive timings of the duplicate packets over the multiple wireless links. The receiver may transmit a report containing the synchronization information to the transmitter periodically and/or in response to a trigger event.

Abstract: Systems, apparatuses, and methods for notification support in extended discontinuous reception mode. A base station and UE may configure eDRX communication. An indication may be received during the eDRX communication. The network may cache the indication. The network may modify the DRX configuration. The network may use a wake up signal. In response, the UE may receive the indication while achieving power savings from the eDRX configuration.

Abstract: A user equipment (UE) device may reside in a state of dual connectivity with a master cell group (MCG) and a secondary cell group (SCG), wherein the radio access technologies of the MCG and the SCG are different. While in the dual connectivity state, the UE device may transition to a mode of reduced activity (e.g., processing and/or RF activity) relative to the secondary cell group (SCG) in order to save power, e.g., when traffic flow via the SCG is below a threshold, or when scheduling activity on the SCG is low. Various mechanisms may be employed to reduce activity, e.g., mechanisms such as reduction of beam monitoring, deactivation of secondary cells of the SCG, reduction of number of active antenna elements, employment of longer periods for periodic measurement and reporting processes, etc.
