  • Patent number: 11342947
    Abstract: Disclosed in some examples are systems, methods, devices, and machine-readable mediums for improved communications between a software-defined radio front-end device and a network-based computing device. Rather than packetize samples together, same bit positions from multiple ADC samples may be packetized together. If a Quality of Service (QoS) metric of the network connection between the RF front-end device and the network-based processing computing drops below a threshold, the RF front-end device may prioritize sending packets with the more significant bits over packets with less significant bits. In other examples, the RF front-end device may prioritize samples corresponding to certain data types over other data types.

  • Patent number: 11088940
    Abstract: Cooperative Multipath (referred to herein as ‘CM’) significantly improves upon the current state of the art for multipath HTTP and MP-TCP. In CM, a client application will discover and/or connect to N endpoints, over N different paths. Preferably these different paths go through different networks. Hence, each path may provide a unique communication channel, potentially with unique characteristics. A typical (but not limiting) case would be N=2, with the client application connecting over, for example, cellular interface to a first endpoint, and over WiFi to a second endpoint. Wireline interfaces may also be used.

  • Patent number: 11082157
    Abstract: A system is configured to measure a forward error correction (FEC) decoding property associated with applying FEC decoding to FEC-encoded bits or symbols at a receiver device deployed in a communication network. The system is further configured to provide an assessment of operating conditions of the receiver device based on the FEC decoding property. In one example, the FEC decoding property comprises a distribution of a number of iterations of a FEC decoding operation applied to a plurality of FEC blocks processed within a period of time. In some examples, the FEC decoding property comprises any one of heat, temperature, current, voltage, active clock cycles, idle clock cycles, activity of parallel engines, activity of pipeline stages, and input or output buffer fill level of the FEC decoding. In some examples, the assessment is based on a comparison between the FEC decoding property and reference FEC data.

  • Patent number: 11039476
    Abstract: In an 802.11ax network with an access point, a trigger frame offers random resource units to nodes for data uplink communication to the access point. To dynamically adapt the contention mechanism used by the nodes to access the random resource units, the AP updates a correcting TBD parameter at each new TXOP and includes the updated adjusting parameter in the trigger frame for the next TXOP. The nodes use the TBD parameter to generate a local random RU backoff value from a contention window range, for contending for access to the random resource units. The TBD parameter may directly impact the contention window size CWO or boundaries values of a selection range from which CWO is selected.

  • Patent number: 11005768
    Abstract: The invention sets out a method where a critical loading related to jitter associated with a link between the access point and a client device is determined. This critical load is the load beyond which retransmissions are insufficient for the client device to repair the video stream. The critical load is determined by sending data at varying transmission rates during a calibration mode, and measuring the jitter and packet loss rate. A safe load is then set as a fraction of this critical load. The loading associated with a multicast stream is then monitored with reference to this safe load, and if the safe load is met or exceeded, then action is taken to avoid packet loss increasing to a critical level. One action may be to adjust the transmission rate of the multicast stream for example, such that the load is reduced to below the safe load level.
