Adaptive neighbor awareness networking (NAN) data interface

A wireless communication device comprising:

• at least one modem;
• at least one processor communicatively coupled with the at least one modem;
• and
• at least one memory communicatively coupled with the at least one processor and storing processor-readable code that, when executed by the at least one processor in conjunction with the at least one modem, is configured to:
• establish a neighbor awareness networking (NAN) device link (NDL), over a wireless channel, with a NAN device;
• negotiate, with the NAN device, an NDL schedule indicating a number of NAN slots, per discovery window (DW) interval, during which the NDL is available for data communications with the NAN device;
• measure congestion on the wireless channel during each of a plurality of NAN slots within a DW interval, the congestion measured during each NAN slot being associated with a respective amount of time (Tbusy) that the wireless channel is busy during the respective NAN slot;
• measure throughput on the NDL during each of the plurality of NAN slots, the throughput measured during each NAN slot being associated with an amount of time (Tload) that the wireless communication device communicates with the NAN device, over the NDL, during the respective NAN slot;
• and
• dynamically update the NDL schedule based on the congestion measured during the plurality of NAN slots and based on the throughput measured during the plurality of NAN slots, the dynamic updating comprising adjusting the number of NAN slots, per DW interval, during which the NDL is available for data communications with the NAN device based on a covariance of Tbusy and Tload.

A method for wireless communication by a wireless communication device, comprising:

• establishing a neighbor awareness networking (NAN) device link (NDL) with a NAN device;
• negotiating, with the NAN device, an NDL schedule indicating a number of NAN slots, per discovery window (DW) interval, during which the NDL is available for data communications with the NAN device;
• measuring throughput on the NDL during each of a plurality of NAN slots within a DW interval, the throughput measured during each NAN slot being associated with an amount of time (Tload) that the wireless communication device communicates with the NAN device, over the NDL, during the respective NAN slot;
• measuring congestion on a wireless channel associated with the NDL during each of the plurality of NAN slots, the congestion measured during each NAN slot being associated with an amount of time (Tbusy) that the wireless channel is busy during the respective NAN slot;
• and
• dynamically updating the NDL schedule based on the throughput measured during the plurality of NAN slots and based on the congestion measured during the plurality of NAN slots, the dynamic updating comprising adjusting a periodicity of the NAN slots, per DW interval, during which the NDL is available for data communications with the NAN device based on a standard deviation of Tload.
