A method of managing a wireless communication between a plurality of accessory devices and a host device includes, at the host device, establishing a data connection with a plurality of accessory devices, obtaining a radio ID for each accessory device of the plurality of accessory devices, grouping the plurality of accessory devices into at least one OFDMA device and at least one non-OFDMA device based at least partially on the radio IDs, sending a trigger signal to the at least one OFDMA device; and after receiving a first response signal from the at least one OFDMA device in response to the trigger signal, receiving a second response signal from the at least one non-OFDMA device.

Mixed standard accessory device communication utilizing host-coordinated transmission

An electronic device includes a processor, a wireless communication device, and a hardware storage device. The hardware storage device has instructions stored thereon that, when executed by the processor, cause the electronic device to obtain a plurality of data channel personalities. Each of the data channel personalities includes a unique radio communication and network protocol for the wireless communication device. The instructions further cause the electronic device to select a data channel personality from the plurality of data channel personalities and transmit data to a host device using the wireless communication device and the radio communication and network protocol according to the selected data channel personality.

Accessory device communication utilizing multiple personalities

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.

Multidimensional service differentiation for WiFi traffic

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.

Systems and methods for proactive wireless communication rate adaptation

A host 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 has instructions stored thereon that, when executed by the processor, cause the host device to establish a wireless data channel with an accessory device and assign the wireless data channel to a resource unit with a bandwidth less than 20 MHz. The instructions further cause the host device to send a trigger signal to the accessory device and receive state data from the accessory device in response to the trigger signal.

Accessory device communication utilizing host-synchronized transmission

A communication device cognitively monitors interference signals across a communication band so that adaptations for physical and medium access control (MAC) of data packet transmissions are appropriate for a particular interference signal. Characteristics of an interference signal of interest (e.g., bandwidth, power and/or duration relative to an average data packet transmitted over a communication channel of the communication device) are sensed for an appropriate adaptation (e.g., forward error correction, modulation technique, back off, request to send/clear to send protocol, etc.). Patterns for known types of interference sources can be compared so that when recognized an associated adaptation can be used.

Physical and MAC adaptation for interference mitigation with cognitive radio

Each node or link of an ad hoc network assists in the distributed allocation of a data channel to increase fairness, even in a multi-hop network, by tracking a measure of link weight for itself and sharing this information over a control channel with neighboring nodes. The metric can be provided over a dedicated control channel, added as a header to data communication on a data channel, or inferred by monitoring data traffic from the neighboring node. The link weight can be adjusted by a link quality factor based on provided or inferred metrics such as transmission rates, ratio of transmission errors, idle time, etc. For multiple flow queues at a subject node, one with a higher transmission rate can be selected for increased fairness. When a packet is received, medium access includes allocating bandwidth, including bonding multiple frequencies that are determined to be available to both nodes.
