Abstract: Various embodiments include an automobile network device that includes a descriptor sorting engine (DSE). The DSE may include a direct memory access (DMA) controller, a memory organized by channel clusters that each include a plurality of first-in first-out (FIFO) memories, a timer, and a time stamp (TS) sorting logic component. The DMA controller may be configured to pull timestamp-pointer pairs from packet descriptors stored in an unsorted descriptor ring memory, store the timestamp-pointer pairs in the FIFO memories, trigger the TS sorting logic component to reorder the timestamp-pointer pairs in the FIFO memories so that they are sorted in ascending order, use the sorted timestamp-pointer pairs in the FIFO memories to read the packet descriptors stored in an unsorted descriptor ring memory, and store the packet descriptors in a sorted descriptor ring memory.

Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus transmits, by a user equipment (UE), a packet to a network entity, while the UE is in a radio resource control (RRC) connected mode. The apparatus determines an acknowledgment (ACK) is absent for the transmitted packet. The apparatus determines to retransmit the packet based at least on whether the UE is in the RRC connected mode or on a type of the packet, upon determining the ACK is absent. The apparatus may determine to retransmit the packet by retransmitting the packet upon determining the UE is in the RRC connected mode. The apparatus may determine to retransmit the packet by suppressing retransmission of the packet upon determining that the UE is not in the RRC connected mode.

Abstract: Systems, methods, and devices of the various embodiments provide a multipath communication scheduler for an in-vehicle computing device, such as a vehicle's autonomous driving system, vehicle's telematics unit, vehicle's control system, etc. In various embodiments, a distributed leaky bucket based scheduler for an in-vehicle computing device may assign packets for transport to a plurality of modems based at least in part on the determined delivery delays. In various embodiments, delivery delays may be determined based on leaky bucket levels, burst sizes, delivery rates, and end to end delay estimates for each of the plurality of modems. In various embodiments, the scheduler may be one of a plurality of schedulers each associated with a separate stream of packets assigned to the plurality of modems and the leaky bucket levels may be determined on a per stream basis.

Abstract: The present disclosure presents a method and an apparatus for packet filtering to save power at a user equipment (UE). For example, the disclosure presents a method for receiving a packet filtering configuration message, at a modem processor (MP) of the UE, from an application processor (AP) in communication with the MP, wherein the packet filtering configuration message includes one or more packet filtering rules for filtering packets associated with one or more applications, configuring a packet filter at the MP based at least on the one or more packet filtering rules received in the packet filtering configuration message, and enabling the configured packet filter at the MP in response to receiving an indication from the AP that the AP entered a low power or sleep mode, wherein the enabled packet filter allows or drops a packet based on the packet filtering rules. As such, packet filtering to save power at UE may be achieved.

Abstract: Aspects of the present disclosure generally relate to wireless communications. In some aspects, a device may determine, during a first time period when a power saving feature is disabled, a first performance parameter associated with an application executing on a user equipment (UE). The device may determine, during a second time period when the power saving feature is enabled, a second performance parameter associated with the application executing on the UE. The device may determine whether to enable or disable the power saving feature for the application based at least in part on the first performance parameter and the second performance parameter.

Abstract: Various embodiments provide methods performed by an modem-assisted-service-classification (MASC) client application operating on a multi-SIM computing device for implementing MASC functionality for two or more subscriptions. In various embodiments, the MASC client may implement MASC functionality by associating MASC policies for one or more access point names (APNs) with a specific subscription and by applying those policies to applications associated with those one or more APNs while that specific subscription is in active communication with its network. Thus, by managing a mapping of subscriptions, APNs/networks, and applications, the MASC client may enable implementation of MASC functionality for a multi-SIM computing device.
