1. A method, comprising:
- applying a first modulation and coding scheme to a first part of a symbol;
applying a second modulation and coding scheme to a second part of the symbol; and
combining the first part of the symbol and the second part of the symbol to form the symbol to be transmitted,wherein the first modulation and coding scheme differs from the second modulation and coding scheme and wherein the first part of the symbol is temporally different from the second part of the symbol.

Abstract
A method can include applying a first modulation and coding scheme to a first part of a symbol, applying a second modulation and coding scheme to a second part of the symbol, and combining the first part of the symbol and the second part of the symbol to form the symbol to be transmitted. The first modulation and coding scheme differs from the second modulation and coding scheme and wherein the first part of the symbol is temporally different from the second part of the symbol.
