The embodiment of the invention provides an information transmission method and a terminal. The method is applied to a terminal supporting scheduling-free transmission, and the method comprises the following steps: detecting the quantity of feedback information continuously fed back by network equipment based on data transmission of the terminal in a time window; determining the MCS level of the terminal according to the mapping relationship between the quantity of the feedback information and the MCS; and performing data transmission according to the determined MCS level. According to the scheme of the invention, when the scheduling-free transmission terminal supporting the non-orthogonal multiple access technology is in a non-connection state, the MCS used by the scheduling-free transmission terminal can be determined based on the mapping relationship between the number of the feedback information and the MCS, and link adaptive transmission is carried out, so the signaling overhead is saved. 本发明的实施例提供一种信息传输
