Abstract: Methods, apparatus, and computer-readable media are described to encode, by a first station (STA), a polling signal for periodic transmission to a second STA during each air activity instance of a plurality of air activity instances. The first STA detects an interface between a MAC layer and a software stack of a communication protocol is in a low-power state. The communication protocol is associated with a communication link between the first STA and the second STA. An empty packet from the second STA is decoded. The empty packet is received in response to the polling signal transmitted during an air activity instance of the plurality of air activity instances. The periodicity of the periodic transmission of the polling signal is adjusted based on the detected low-power state and the decoded empty packet.

Abstract: Apparatus includes a plurality of ports and arbitration circuitry. The plurality of ports is configured to connect a memory to a respective plurality of processing units that are configured to access the memory. The arbitration circuitry is configured to grant the processing units access to the memory via the ports in accordance with an arbitration scheme including multiple, alternating priority periods, such that in each priority period a respective processing unit is assigned an absolute priority over others of the processing units and the others of the processing units are assigned predefined relative priorities over one another.

Abstract: A turbo decoder has at least two Bahl, Cocke, Jelinek, and Raviv (BCJR) processors in parallel, each in serial communication with respective interleavers. The BCJR processors and interleavers are in communication with a memory module that is internally split into non-overlapping memory banks. The turbo decoder includes respective sorter circuits in communication with the output of each BCJR processor/interleaver. A sorter circuit receives a data block from a BCJR processor/interleaver and directs the data block to the memory bank designated by an address assigned to the data block by an interleaver.
