Abstract: Techniques, described herein, include solutions for enabling inter-user equipment (UE) coordination (IUC) using media access control (MAC) control elements (CE). A first UE may send an IUC request to a second UE, and the second UE may respond with a MAC CE that includes IUC information. The IUC information may indicated one or more wireless resources that the first UE may use to communicate with the second UE. The IUC information may also include a time-domain validity for wireless resources, which may include one or more durations of time the wireless resources may be used for communication. The first UE may also implement a latency bound during which the second UE is to respond with the IUC information. In some implementations, discontinuous reception (DRX) may be used by the first and second UEs, and DRX active times of the UEs may be modified or configured to facilitate IUC.

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 techniques for providing paging for a remote wireless device to a relay wireless device in a wireless communication system. A cellular base station may receive an indication from a relay wireless device of a relay link between the relay wireless device and a remote wireless device. The cellular base station may provide paging information for the remote wireless device to the relay wireless device based at least in part on the indication of the relay link between the relay wireless device and the remote wireless device.

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: User equipment devices (UEs) may receive multimedia broadcast and multicast service (MBMS) transmissions over a bandwidth part (BWP) specifically allocated for MBMS point-to-multipoint (PTM) transmissions, or over MBMS-specific resources configured for PTM transmissions within a UE-dedicated BWP. The network (e.g. base station) may configure the MBMS-specific BWP for the UE for the PTM transmissions per serving cell. The MBMS-specific BWP may be used for downlink transmissions, and may be cell specific or UE specific per serving cell. The base station may provide MBMS PTM scheduling information per BWP to the UE, may indicate whether a UE-dedicated BWP may be used for PTM scheduling and transmission, and may provide the corresponding scheduling configuration when applicable. The UE may communicate its various capabilities related to MBMS reception and simultaneous reception of PTM and point-to-point (PTP) transmissions to the base station to aid the base station in scheduling communications of the UE.

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: An example technique for security key derivation in a wireless system includes: sending a radio resource control (RRC) suspend message from a first node, to a first user device, the RRC suspend message including a first next hop (NH) chaining counter (NCC) value; releasing access stratum (AS) resources associated with the first user device; deriving a first node key based on the first NCC value; receiving a first uplink message from the first user device without allocating AS resources to the first user device; and unscrambling the first uplink message based on the first NCC value.
