Abstract: Systems and methods for dynamically adapting channel access or transmission parameters based upon an identified channel access parameter or previously used transmission parameter are disclosed. In an aspect, an electronic device for communication over a wireless network is disclosed. The electronic device comprises a processor configured to generate a message that identifies one rule of a plurality of rules. Each of the plurality of rules defines a process for adapting a value of a communication parameter based on an identified channel access parameter. Also, each of the plurality of rules provides a particular quality of service and a particular priority for communication with the electronic device. The electronic device further comprises a transceiver configured to transmit the message to a station.

Abstract: Systems, methods, and devices for wireless communication are disclosed. In one implementation an apparatus for wireless communications is provided. The apparatus includes a receiver configured to receive a wake-up message that is a portion of a wake-up sequence. In certain implementations, the apparatus further includes a processing system operably coupled to the receiver and configured to wake the receiver for a period of time. The period of time can exceed at least a transmission period of the wake-up sequence plus a transmission period of the wake-up message. The apparatus can further include a transmitter configured to transmit a message acknowledging receipt of the wake-up message.

Abstract: Systems, methods, and devices for concurrently allowing station-to-station transmissions and access point-to-station transmissions are described herein. In some aspects, a method comprises transmitting, to an access point, a request for an available channel frequency. The method further comprises receiving a coordination message from the access point. The coordination message may indicate that a first frequency channel is allocated for transmissions between a first device and a second device and that a second frequency channel is allocated for transmissions between a third device and a fourth device. The method further comprises transmitting a first data packet to the fourth device using the second frequency channel concurrently with a transmission of a second data packet between the first device and the second device using the first frequency channel.
