Claim:
1. An open-loop link adaptation adjusting method, characterized by comprising: classifying, by a base station, states of a user equipment during an information transmission process; configuring, by the base station, an open-loop link adaptation adjusting (OLLA) value for each of the classified states corresponding to the user equipment respectively; determining, by the base station, a current state of the user equipment during the information transmission process, 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 adjusting, by the base station, a modulation and coding scheme (MCS) value according to the OLLA value corresponding to the current state of the user equipment, and then modifying the OLLA value corresponding to the current state of the user equipment; wherein the classifying, by the base station, the states of the user equipment during the information transmission process comprises: classifying, by the base station, the states of the user equipment during the information transmission process according to at least one classification condition of a rank of the user equipment, a number of layers of the user equipment during the transmission process, a total number of layers of the user equipment configured by the base station during the transmission process, and a preset state of the user equipment in a system.
