Learning-based wireless transmission parameter adaptation based on client activity detection

An apparatus comprising:

• a radio to transmit packets to a client device over a communication channel used by the client device;
• and
• a processor coupled to the radio and configured to:
• determine a motion indictor indicative of motion of the client device based on a sequence of channel state information measurements;
• measure a signal-to-noise ratio (SNR) of the communication channel;
• select a transmission parameter among candidate transmission parameters using a learning-based algorithm based on observation parameters including the motion indicator, the SNR, and a device identifier for the client device;
• employ the transmission parameter to transmit packets to the client device;
• measure a transmission performance associated with the transmission parameter based on the transmit packets;
• and
• update the learning-based algorithm based on the observation parameters and the transmission performance for a next pass through the select, the employ, and the measure operations.

A non-transitory computer readable medium encoded with instructions that, when executed by a processor of an access point configured to transmit packets to a client device over a communication channel used by the client device, cause the processor to perform:

• determining a motion indictor indicative of motion of the client device based on a sequence of channel state information measurements;
• measuring a signal-to-noise ratio (SNR) of the communication channel;
• selecting a transmission parameter among candidate transmission parameters using a learning-based algorithm based on observation parameters including the motion indicator, the SNR, and a device identifier for the client device;
• employing the transmission parameter to transmit packets to the client device;
• measuring a transmission performance associated with the transmission parameter based on the transmit packets;
• and
• updating the learning-based algorithm based on the observation parameters and the transmission performance for a next pass through the selecting, the employing, and the measuring.
