Abstract: Provided are a method and device for sending control information and receiving control information. The method for sending control information comprises repeatedly sending control information within a scheduling period of the control information M times, wherein the scheduling period is the length of N radio frames, N and M are positive integers greater than 1, and N is greater than or equal to M. The disclosure solves the technical problem in the related art that control information cannot be correctly received in a low-coverage environment and thus a terminal cannot normally access a network, achieving the technical effect of accurately receiving the control information so as to ensure that the network can be accessed normally.
