1. A system comprising:
a first device and a second device,
wherein the first device comprises:
one or more first processors; and
first memory storing instructions that, when executed by the one or more first processors, cause the first device to:
receive, from the second device, via a plurality of tones, and during a corresponding plurality of time slots, a plurality of pilot signals;
determine, for the second device and based on the received plurality of pilot signals, a plurality of effective modulation rates respectively associated with the plurality of tones;
determine, based on the plurality of effective modulation rates, a tone, of the plurality of tones, for a subsequent transmission from the second device; and
send, to the second device, information indicating the determined tone, and
wherein the second device comprises:
one or more second processors; and
second memory storing instructions that, when executed by the one or more second processors, cause the second device to:
send, to the first device and based on a pilot signal schedule, the plurality of pilot signals; and
receive, from the first device, the information indicating the determined tone.
