  • 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: 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.
