  • Patent number: 12690059
    Abstract: Short-term fading can be addressed through channel hopping mechanisms in the time scale of few milliseconds. Existing do not address short-term fading. For example, Wi-Fi channel change mechanisms take several 100 ms to perform a channel change. Short-term fading lasts around 80 ms and those methods would not detect or solve issues with missing packets at this speed. The present disclosure proposes a novel method where, a computer and all other devices, e.g., a game console and game controllers, switch channels every 8 to 16 ms through a pre-agreed upon channel sequence. Thus, even if one of the channels is undergoing a deep fade, the controllers/console will be able to leverage other channels to minimize packet loss rates.

  • Publication number: 20250286648
    Abstract: A first device includes a processor, a wireless communication device in data communication with the processor, and a hardware storage device in data communication with the processor. The hardware storage device includes instructions stored thereon that, when executed by the processor, causes the host device to compare a Quality of Server Subtype (QoS-Subtype) value to a matching rule of a policy table stored on the hardware storage device, determine a transmission policy based at least partially on the QoS-Subtype value, wherein the transmission policy includes a transmission rate with a modulation and coding scheme (MCS) index based at least partially on the QoS-Subtype, and transmit a transmission to a second device according to the transmission policy.

  • Publication number: 20250260461
    Abstract: A method of managing wireless communication between electronic devices includes, at a first electronic device, transmitting a first downlink transmission from the first electronic device to a second electronic device and receiving a first response from the second electronic device at the first electronic device, wherein the first response includes a downlink channel quality information (CQI). The method further includes determining a per-subcarrier CQI based at least partially on the downlink CQI and determining an output modulation and coding scheme (MCS) based at least partially on the per-subcarrier CQI. After determining the output MCS, the method includes selecting a selected MCS based at least partially on the output MCS and setting an MCS of the first electronic device to the selected MCS.

  • Patent number: 10368310
    Abstract: A computing device may include an accessory radio that facilitates point-to-point wireless connectivity between the computing device and one or more accessory devices. The accessory radio may periodically broadcast its presence to the one or more accessory devices while operating in an active state. The accessory radio may transition from the active state to a sleep state after a period of inactivity. The computing device may also include a general purpose radio that may facilitate general wireless connectivity between the computing device and other devices. The general purpose radio may listen for any messages that are intended for the accessory radio while the accessory radio is in the sleep state. The general purpose radio may activate the accessory radio in response to the general purpose radio receiving a message, while the accessory radio is in the sleep state, that satisfies at least one activation condition.
