Abstract: A user equipment (UE) configured to receive a first cumulative acknowledgement (ACK) from a protocol stack of the UE at a first time, store the first cumulative ACK in a queue, receive a second cumulative ACK from the protocol stack at a second time, wherein the second time occurs after the first time, store the second cumulative ACK in the queue, discard the first cumulative ACK from the queue based on the second cumulative ACK being received after the first cumulative ACK and encapsulate the second cumulative ACK to form a radio link control (RLC) packet data unit (PDU) that is to be transmitted over the air.

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: A relay user equipment (UE) configured to operate as a relay between a remote UE and a network component performs a method. The method includes determining at least one relay capability of the relay UE and performing a relay access control operation that indicates to the remote UE whether the remote UE is permitted to use the relay UE as the relay.

Abstract: A user equipment (UE) is configured to deactivate/activate a point-to-multipoint (PTM) link of a multicast radio bearer (MRB). The UE receives, from a base station of a wireless network, a multicast radio bearer (MRB) configuration, wherein the MRB includes configuration of a split MRB including a point to multipoint (PTM) link and a point to point (PTP) link, deactivates or activates the PTM link based on the MRB configuration, reestablishes a radio link control (RLC) associated with the PTM link and recovers a packet data convergence protocol (PDCP).

Abstract: This disclosure relates to techniques for performing paging forwarding for remote wireless devices in a wireless communication system. A relay wireless device and a remote wireless device may establish a relay link. The relay wireless device may provide an indication of the relay link between the relay wireless device and the remote wireless device to a cellular base station. The relay wireless device may receive paging information for the remote wireless device from the cellular base station. The relay wireless device may provide the paging information to the remote wireless device via the relay link between the relay wireless device and the remote wireless device.

Abstract: Systems and methods are disclosed herein for using integrated access and backhaul (IAB) nodes configured to provide multi-access edge computing (MEC) functionality. An IAB node may include a MEC functionality that includes an instance of an application configured for MEC. A UE using the application connects to the network through an access link with the IAB node and establishes a PDU session for traffic of the application with a core network (CN). The CN may determine that the traffic corresponds to the application, and that an instance of the application is present on the IAB node. Accordingly, the CN may instruct the IAB donor to instantiate a remote packet data convergence protocol (PDCP) layer and, in some cases, a remote service data application (SDAP) layer that are configured to route the traffic from the UE for the application to the instance of the application on the IAB node.

Abstract: A user equipment (UE) configured to monitor paging occasions of a network. The UE operates in a paging discontinuous reception (DRX) cycle, wherein the DRX cycle includes a paging occasion (PO). The UE determines a location in time for a wake-up signal (WUS) occasion associated with the PO and determines whether to utilize an active mode or a sleep mode during the PO based on an indication included in a WUS received during the WUS occasion.
