  • Patent number: 10931547
    Abstract: Some embodiments of the invention provide a data-plane forwarding circuit (data plane) that can be configured to identify large data message flows that it processes for forwarding in a network. In this document, large data message flows are referred to as heavy hitter flows. To perform its forwarding operations, the data plane includes several data message processing stages that are configured to process the data tuples associated with the data messages received by the data plane. In some embodiments, parts of the data plane message-processing stages are also configured to implement a heavy hitter detection (HHD) circuit. The operations of the data plane's message processing stages are configured by a control plane of the data plane's forwarding element in some embodiments.

  • Patent number: 10932287
    Abstract: Methods, systems, and devices for dynamic monitoring and scheduling in retransmission are described for wireless communications. For example, a receiving device may receive a data transmission in a first receiver bandwidth, determine that a data packet of the data transmission was unsuccessfully decoded, switch to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth (e.g., based on determining that the data packet was unsuccessfully decoded), and receive a retransmission of the data packet in the second receiver bandwidth. In another example, a transmitting device may schedule a data transmission according to a first receiver bandwidth, receive an indication that a data packet of the data transmission was unsuccessfully decoded, and schedule a retransmission of the data packet according to a second receiver bandwidth that is wider than the first receiver bandwidth or narrower than the first receiver bandwidth.

  • Patent number: 10893385
    Abstract: The invention provides methods, systems, and devices for detecting a physical collision between two client devices based on sensor data. A server computer receives a first collision signature from a first client device, and a second collision signature from a second client device. Based on determining that a correlation of the first collision signature and the second collision signature does not achieve a detection threshold, the server computer lowers, for a limited period of time, the detection threshold. If the server computer receives, within the limited period of time, a third collision signature from the first client device, and a fourth collision signature from the second client device, and determines that a correlation of the third collision signature and the fourth collision signature achieves the lowered detection threshold, the server computer detects a collision between the first and second client devices.

  • Patent number: 10834750
    Abstract: Methods, systems, and devices for wireless communication are described. A user equipment (UE) and a base station may use low latency communications to improve the throughput of a wireless link. To facilitate efficient low latency communication, the UE may send UE-initiated CSI reports in addition to periodic and base station-initiated reports. For example, the UE may, in various examples, send UE-initiated CSI reports using contention based spectrum, using a request-to-transmit, or using a CSI differential (i.e., an indicator of a change in channel conditions). The base station may schedule different UEs for uplink low latency communication by providing resources to each UE for CSI and scheduling requests (SRs) using coherent or non-coherent uplink transmissions. The CSI and SR may also be combined with uplink feedback.

The UE receives a semi-static assignment from a network, indicating each of a plurality of symbol periods in a slot being assigned as one of: a downlink symbol period, a semi-static unknown symbol period, and an uplink symbol period. The UE receives a dynamic slot format indicator (SFI), the dynamic SFI indicating M of the plurality of symbol periods being reassigned dynamically from semi-static unknown symbol periods to symbol periods not being monitored by the UE for PDCCH data. The UE determines that a CORESET of Y symbol periods contains N of the M reassigned symbol periods. The UE (1) refrains from decoding data carried in the Y symbol periods of the CORESET or (2) decodes data carried in (Y-N) symbol periods of the CORESET with exclusion of data carried in the N reassigned symbol periods of the CORESET.
