1. A method, comprising:
- selecting, based on an optimal tone map, a particular subcarrier for use when transmitting a data frame, the data frame to serve as a tone map request (TMREQ) data frame;
populating one or more unused quality subcarriers of the TMREQ data frame other than the particular subcarrier with a well-known bit sequence, wherein the TMREQ data frame indentifying a use of each subcarrier during transmission; and
transmitting the TMREQ data frame to a receiving device to cause the receiving device to evaluate transmission quality of the one or more unused quality subcarriers based on the well-known bit sequence.

Abstract
In one embodiment, a device may select, based on an optimal tone map, a particular subcarrier for use when transmitting a data frame, the data frame to serve as a tone map request (TMREQ). The device may then populate one or more unused quality subcarriers of the TMREQ data frame other than the particular subcarrier with a well-known bit sequence, and transmits the TMREQ data frame to a receiving device to cause the receiving device to evaluate transmission quality of the one or more unused quality subcarriers based on the well-known bit sequence.

12. A method, comprising:
-
receiving, from a source device, a data frame on a particular subcarrier; determining if the data frame serves a tone map request (TMREQ) data frame; evaluating transmission quality of one or more unused quality subcarriers based on the well-known bit sequence if the data frame is a TMREQ, wherein the TMREQ data frame indentifying a use of each subcarrier during transmission; and transmitting a tone map reply (TMREP) to the source device in response to the TMREQ.
