  • Patent number: 11026284
    Abstract: A timeout period for a base station to wait for a UE's response to bearer-setup messaging from the base station will be set based on an evaluation of how often the UE (or a class of UEs of which the UE is a member) has experienced bearer-setup failures. For instance, the base station could generally apply a default timeout period for waiting to receive bearer-setup response messaging from UEs. But for a given UE that has recently experienced a high rate of bearer-setup failures, the base station could apply a longer timeout period, to help cope with that UE's tendency to be slower to respond to the base station's bearer-setup messaging.

    Abstract: Personal area network (PAN) functionality is partitioned between a pod cluster controller (PCC) and one or more separately housed “pods” with which it communicates. A pod includes a transceiver, providing the PAN to some area. The PCC communicates audio and control data with its pods, which together form a cluster, and may provide power to them. The structure of a pod can be simple, because the PCC can handle various services on behalf of its pods—for example, the PCC can interface with external analog audio devices (e.g., audio speaker, microphone); digital devices; peripherals; or the Internet. The PCC may encode/decode and multiplex/mix audio data. The partitioning can mitigate various PAN issues such as line-of-sight and metal interference, and can extend a pod cluster to have arbitrarily large PAN spatial coverage.

  • Patent number: 10356779
    Abstract: A wireless communication network that forms an ad-hoc network without the arrangement of a controlling station sets a period that a communication apparatus can utilize with priority and performs isochronous communication in the period as required. When isochronous communication has not been performed or after isochronous communication has finished in the priority utilization period, other communication apparatuses perform arbitrary communication. When another communication is performed in a communication apparatus's own priority utilization period, the start of isochronous communication is temporarily delayed. In an ad-hoc communication environment, data having a real-time characteristic, such as AV content, can be efficiently transmitted through the isochronous communication.

  • Patent number: 10320492
    Abstract: A system and method for minimizing or preventing interference between wireless networks is disclosed. A network hub broadcasts a beacon signal within repeating beacon periods. The position of the beacon signal shifts within each beacon period based upon a predetermined pseudo-random sequence. The beacon signal includes data identifying the current beacon shift sequence and the current phase of the sequence. Neighboring hubs independently or jointly determine and broadcast their own beacon shift sequences and phases for their respective networks from a predetermined list. Nodes connected with the network hubs are assigned allocation intervals having a start time that is set relative to the beacon signal. The start time and duration of the allocation interval wraps around the beacon period if the allocation-interval would otherwise start or continue in a next beacon period.

  • Patent number: 10129165
    Abstract: An electronic device may include first and second antennas and a Bluetooth transceiver. Control circuitry may perform Bluetooth antenna diversity operations by coupling the Bluetooth transceiver to a selected one of the first and second antennas at a given time. The Bluetooth transceiver may transmit a first Bluetooth data packet and may determine whether a scheduled response packet associated with the first packet has been received over the first antenna during a predetermined time period. In response to determining that the Bluetooth transceiver has failed to receive the scheduled response packet during the first predetermined time period, the Bluetooth transceiver may re-transmit the first packet using the second antenna. This may serve to reduce the error rate of the transmitted Bluetooth data over time relative to scenarios where a single antenna is used, without requiring resource-intensive sensor circuitry to actively monitor the performance of the antennas.
