  • Patent number: 11962325
    Abstract: A system and method for detecting the preamble of a wireless packet is disclosed. The system utilizes one or more received fragments as inputs to a correlator, forming correlator content inside the correlator memory. After every sample from the received fragment is provided to the correlator, the correlator then compares the correlator content to a known pattern pre-programmed as a set of correlation coefficients. The correlation coefficients may not align with the correlator content because the symbol boundaries are not known a-priori. By cyclic rotation of the correlation coefficients relative to the correlator content, or cyclic rotation of the correlator content relative to the known correlation coefficients, a match with one or more preamble symbols may be found. This technique may be used to reduce power during the preamble detection process. Alternatively, this technique can also be used for antenna diversity, multi PHY and multichannel applications.

The reuse of the mechanism is enabled by assigning each processor a vertical neighbour on its opposing die. Each processor has an interdie connection that connects it to the output exchange bus of its neighbour. A processor is able to borrow the output exchange bus of its neighbour by sending data along the output exchange bus of its neighbour.

  • Patent number: 11546111
    Abstract: Disclosed are methods for base stations to indicate the start and end of a downlink message, by prepending and appending demarcations to the message in 5G or 6G. A user device can then readily locate the message by detecting the demarcations, greatly reducing the amount of computation required of the receiver processor. There may be no need for a DCI message alerting the user device of the coming message. Each demarcation may be a brief predetermined bit sequence such as a demodulation reference or an identification code of the intended recipient. The start and end demarcations may be different, and may include a gap of zero or low transmission, to further assist the receiver. The user device may transmit a request message to the base station, requesting that demarcations be applied to the user's downlink messages, and declining the redundant DCI alert messages, thereby saving further energy and network overhead.

    Abstract: Antenna elements support RF communication over a communication link using frequency channels, RF processing circuits, and configuration circuitry to apply a selected configuration. Each configuration identifies processing circuit to antenna element couplings, and which frequency channel is allocated to each RF processing circuit. A reinforcement learning process is applied to dynamically alter which configuration to apply as a currently selected configuration. The reinforcement learning process maintains a future rewards record having entries that maintain, for an associated combination of link state and configuration, an estimated future rewards indication determined using a discounted rewards mechanism. A selection policy selects a configuration for a current link state, and then a new reward is observed that is dependent on how the selected configuration alters a chosen performance metric for the communication link.

Data is requested in unit of quantum, which may aggregate multiple packets, and which reduces schedule latency. Each request is associated with a start-of-quantum (SoR) state or a middle-of-quantum (MoR) state to support cut-through. The fabric scheduler performs a multi-stage scheduling process to progressively narrow the selection of requests, including stages of arbitration in virtual output port level, virtual output port group level, tile level, egress port level, and port group level. Each tile receives the grants for its requests and accordingly sends request data to a switch fabric for transmission to the destination egress ports.

  • Patent number: 11239943
    Abstract: An FEC coder in a transmission device according to an exemplary embodiment of the present disclosure performs BCH coding and LDPC coding based on whether a code length of the LDPC coding is a 16k mode or a 64k mode. A mapper performs mapping in an I-Q coordinate to perform conversion into an FEC block, and outputs pieces of mapping data (cells). The mapper defines different non-uniform mapping patterns with respect to different code lengths even an identical coding rate is used by the FEC coder. This configuration improves a shaping gain for different error correction code lengths in a transmission technology in which modulation of the non-uniform mapping pattern is used.

    Abstract: A method of using a proxy network to normalize online connections uses a global proxy network (GPN) to manage connections between a plurality of local proxy clients and a destination server. First, an optimization process is executed for the overall network connection between each local proxy client and the destination server. The latency of each optimized connection are then examined to determine a normalization point, which corresponds to the highest latency among the optimized connections. The rest of the connections are then adjusted to conform to the normalization point by adding latency to the connections to match the latency of the normalization point.
