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: Apparatus, methods, and computer-readable media for facilitating autonomous synchronization are disclosed herein. For example, a UE may be configured to perform an initial synchronization directly to PSCCH and PSSCH when other synchronization sources, such as GNSS, a base station, and/or SLSS, are unavailable. An example method for wireless communication at a user equipment includes receiving a PSCCH. The example method also includes performing an initial synchronization based on the PSCCH. In some examples, the method may also include receiving a PSSCH, and determining a logical subframe number modulo 10 based on the PSSCH. The logical subframe number modulo 10 may correspond to a sequence seed.
