1. A robust channel (RC)-supporting coding and modulation method, the method comprising:

  • forming, on an interface between a physical media dependent (PMD) layer and a physical media specific transmission convergence (PMS-TC) layer, a data frame by using bit data carried in a discrete multi-tone (DMT) symbol, wherein the bit data carried in the DMT symbol comprises RC bit data that is obtained from an RC and service bit data that is obtained from a service data channel;

    determining first-part bit data in the data frame as uncoded bit data on the interface between the PMD layer and the PMS-TC layer, wherein the first-part bit data comprises the RC bit data, and coding second-part bit data in the data frame to obtain coded bit data, wherein the data frame comprises the first-part bit data and the second-part bit data;

    mapping, at the PMD layer, the uncoded bit data and the coded bit data onto multiple subcarriers corresponding to the data frame; and

    performing modulation to obtain modulated subcarriers;

    wherein the multiple subcarriers corresponding to the data frame comprise at least one RC subcarrier, and the RC bit data is mapped onto the at least one RC subcarrier.
