Abstract: Disclosed is a transmission method compatible with higher order modulation and lower order modulation, and an apparatus. A base station stores a first higher order modulation mapping table supporting the higher order modulation and a first lower order modulation mapping table supporting the lower order modulation; the base station receives capability level information sent by user equipment; the base station determines, according to the capability level information sent by the user equipment, a first modulation mapping table used to communicate with the user equipment; the base station determines a modulation and coding scheme index according to the modulation mapping table, where the modulation and coding scheme index is used by the user equipment to determine a modulation and coding scheme; and the modulation and coding scheme index is sent to the user equipment.
