Embodiments of the present invention provide an adaptive modulation and coding method and an apparatus, which relate to the communications field and can improve accuracy of MCS selection, thereby improving a system throughput rate. The method includes: acquiring scheduling information of first user equipment in a first cell; acquiring scheduling information of second user equipment in a second cell; acquiring a SINR predictor of the first user equipment according to the scheduling information of the first user equipment in the first cell and the scheduling information of the second user equipment in the second cell; obtaining a SINR adjustment value of the first user equipment according to the SINR predictor and a SINR adjustment amount; and determining, according to a correspondence between a SINR and a modulation and coding scheme MCS, an MCS corresponding to the SINR adjustment value of the first user equipment.
