An information bit determination method and a mapping relationship generation method for polar-coded modulation, and devices thereof are provided. The information bit determination method includes: providing a mapping relationship table for a predefined polar-coded modulation scheme, the mapping relationship table at least including target rates, modulation orders and first parameters of a polar code/component code under different MCS indices; determining the quantity of information bits in each polar code/component code in a target polar-coded modulation system in accordance with the mapping relationship table; and determining an information bit set corresponding to each polar code/component code in accordance with the quantity of information bits in each polar code/component code in the target polar-coded modulation system, the information bit set being used to indicate a set of positions of the information bits. According to the present application, a mapping relationship generation method and an information bit determination method for polar-coded modulation are provided independent of a channel state, so it is able to improve the flexibility and the practicability of the polar-coded modulation scheme.
