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: This disclosure relates to techniques for performing conditional handovers and cell re-selections along known routes. A cellular base station may select a conditional handover set for a wireless device. The conditional handover set may include information for multiple conditional handovers. The wireless device may receive the conditional handover set. The wireless device may perform conditional handover to at least a first cell indicated in the conditional handover set based at least in part on the conditional handover set.

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: 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.

IPC: H04W72/04

Abstract: A user equipment (UE) may detect a collision or interference issues of a second UE and transmit information regarding the detected collision to a base station. The second UE may not able to sense the channel on its own and thus may inadvertently use resources already reserved or in use by other UEs. The information regarding the detected collision may include layer-1 identifiers (L1 IDs) and/or layer-2 identifiers (L2 IDs) corresponding to the UE and/or the second UE as well as additional information corresponding to the resource collision. This information may be usable by the base station in determining that the base station has previously communicated with the second UE and may trigger a resource reselection by the second UE. The UE may receive sidelink communications on one or more reselected sidelink transmission resources from the second UE.

Abstract: A user equipment (UE) is configured to utilize wake up signaling during paging operations. The operates in a paging discontinuous reception (DRX) cycle, wherein the paging DRX cycle includes a paging occasion (PO). The UE receives a wake-up signal (WUS) during a WUS occasion that is associated with the PO and selects a mode of operation to utilize during the PO based on the WUS.

IPC: H04W68/00

Abstract: A user equipment (UE) operates in a network. The UE receives, from the network, a paging area comprising a plurality of cells of the network. When the UE is in one of a radio resource control (RRC) inactive state or RRC idle state with respect to the network, the UE transmits a message to a first cell of the paging area based on the UE moving into a first coverage area of the first cell from a second coverage area of a second cell of the paging area. The UE then monitors the first cell for a page from the network.

Abstract: Embodiments are presented herein of apparatuses, systems, and methods for a user equipment device (UE) and a network to perform flexible acknowledgement. A UE may determine whether or not to solicit feedback (e.g., HARQ ACK/NACK) for one or more groupcast transmissions. The determination may be based on factors such as a remaining time to perform the transmission and the amount of time needed to perform the transmission with and without allowing time to receive and process feedback.
