Abstract: Embodiments of the present invention disclosed an open-loop link adaptation adjusting method and apparatus, firstly, classifying, by a base station, states of a user equipment during an information transmission process, and configuring an open-loop link adaptation adjusting OLLA value for each of the classified states respectively; then, determining, by the base station, a current state of the user equipment, and selecting an OLLA value corresponding to the current state of the user equipment from the OLLA values corresponding to each of the states respectively; and finally, after adjusting a modulation and coding scheme MCS value according to the OLLA value corresponding to the current state of the user equipment, modifying, by the base station, the OLLA value corresponding to the current state of the user equipment. The present invention is applicable to the communication system field.
