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.

Abstract: Systems and methods for control signaling for beam searching latency reduction are disclosed herein. A g Node B (gNB) may determine that a first Synchronization Signal Block (SSB) and a second SSB are to be spatially correlated and may select a first transmit (Tx) beam to transmit the first SSB and a second Tx beam to transmit the second SSB accordingly. The gNB may also transmit a correlation message including spatial correlation information to help a UE determine the spatial correlation. The UE may measure the first SSB on a first subset of a plurality of receive (Rx) beams and measure the second. SSB on a second subset of the plurality of Rx beams, and select an Rx beam for one or both. In some embodiments, channel state information reference signals (CSI-RS) that are quasi co-located (QCLed) with a Oven SSB may be measured in place of the SSB.

Abstract: This disclosure relates to techniques for providing broadcast and multicast services to wireless devices while in idle and Inactive modes a wireless communication system. A wireless device may establish a wireless link with a cellular base station of a cellular network. The wireless device may receive information indicating whether provision of a broadcast or multicast service in one or more of an inactive mode or an idle mode is supported by the cellular network. The wireless device may receive the broadcast or multicast service in one or more of the inactive mode or the idle mode based at least in part on the information indicating whether provision of the broadcast or multicast service in one or more of the inactive mode or the idle mode is supported by the cellular network.

Abstract: A wireless user equipment (UE) may employ any of various mechanisms for reporting signal quality measurements to a wireless network. The UE may impose a time delay between measurement and reporting, based on a delay parameter K. The UE may average measurements obtained at different measurement instances. The UE may employ any of various schemes for prioritizing transmission of one type of report over another, when temporal collisions occur between different types of report. The UE may employ a differential report that includes a state for indicating that a beam is not workable. The UE may employ a beam index that includes a state for indicating an invalid beam. A base station may receive a signal quality report and determine workability of a beam, e.g., by triggering a report of channel state information.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) to perform power control for uplink (UL) reference signals (RS). A UE may determine spatial configuration for UL RS based on another communication. A UE may determine an updated pathloss within a reduced implementation following an update of downlink (DL) RS. A UE may reset a power control factor in response to receiving an update.

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.
