Abstract: An example system and method monitor a wireless transmission medium for packets of a first protocol type with first communication circuits of a device while yielding the medium for communications of a second protocol type by second communication circuits of the device. Responsive to the first communication circuits detecting a packet of the first protocol type while the medium is yielded to the second communication circuits, the system and method requests access to the medium for the first communication circuits and in response to granted access to the medium, uses the first communication circuits to execute a data transmission operation according to the first protocol. Responsive to completing the data transmission operation by the first communication circuits the system and method yield the medium back to the second communication circuits.

Abstract: A method can include selecting a channel from a network operating according to a first protocol (e.g., an IEEE 802.11ax channel). Designating at least one portion of the channel as a shared resource unit (RU) and another portion as a dedicated RU. When an associated device is communicating according to a different protocol (e.g., a Bluetooth standard), allocating frequencies of the shared RU for use by the associated device and allocating the dedicated RUs for use by the network operating according to the first protocol.

Abstract: A device can have collocated communication circuits and operate in a parallel mode if selected first wireless channels are above a certain quality, and operate in a time division (TD) mode if the selected first wireless channels are below a certain quality. The parallel mode can include using first channels for a first protocol that do not overlap a second channel used by a second protocol. The TD mode can include first time periods in which a first protocol uses first channels that overlap the second channel, while the second protocol is inactive, and second time periods, in which the first protocol is inactive and the second protocol is active.

Abstract: Systems, methods, and devices enable coexistence of traffic for collocated transceivers. Methods may include generating, using a processing device, a target-wake-time (TWT) agreement, the TWT agreement being determined based on availability of a first transceiver and a plurality of wireless devices. The methods may also include generating, using the processing device, a medium access schedule for the first transceiver based on a transmission parameter of a second transceiver, the second transceiver being collocated with the first transceiver and sharing a transmission medium with the first transceiver, and the medium access schedule being a TWT schedule. The methods may further include transmitting the TWT schedule to the plurality of wireless devices, the TWT schedule identifying a plurality of wake times and a plurality of sleep times to the plurality of wireless devices.
