Abstract: The present disclosure relates to outer loop link adaptation adjustment methods and apparatus. In one example method, a base station obtains at least one piece of channel quality information of a terminal device, determines, based on the at least one piece of channel quality information of the terminal device and channel quality ranges of a plurality of clusters in a cell, a target cluster to which the terminal device belongs, updates a signal to interference plus noise ratio (SINR) error adjustment amount of the target cluster and a channel quality fluctuation parameter of the cell based on the at least one piece of channel quality information of the terminal device, and finally determines an initial value of an outer loop link adaptation (OLLA) adjustment amount of the terminal device based on the SINR error adjustment amount of the target cluster and the channel quality fluctuation parameter of the cell.
