1. A method for determining a time-domain position of a search space, applied to a communication device, comprising:
determining the time-domain position of the search space corresponding to a terminal, according to terminal parameter information and a search space monitoring periodicity of the terminal;
wherein the terminal parameter information comprises: a terminal identity identifier (UE ID) or a cell radio network temporary identifier (C-RNTI) corresponding to the terminal, and the search space monitoring periodicity of the terminal is a predetermined value;
wherein, the determining the time-domain position of the search space corresponding to the terminal, according to the terminal parameter information and the search space monitoring periodicity of the terminal comprises:
determining, according to the terminal parameter information and the search space monitoring periodicity of the terminal, an index of a time-domain resource of the search space corresponding to the terminal;
wherein, the determining, according to the terminal parameter information and the search space monitoring periodicity of the terminal, the index of the time-domain resource of the search space corresponding to the terminal, comprises:
determining, according to the terminal parameter information and the search space monitoring periodicity of the terminal, the index of the time-domain resource of the search space corresponding to the terminal by using a first formula;
wherein the first formula is: mod (T_index,N)=mod(A,N);
mod represents a modulus operator, T_index represents the index of the time-domain resource of the search space, N represents the search space monitoring periodicity of the terminal, N is a positive integer greater than or equal to 1, and A represents the terminal parameter information.
