Disclosed is a method for sending and receiving signals. The method comprises: sending signals to a receiving end, wherein the signals comprise a first signal and a second signal, the first signal is at least one sequence in a preset sequence set and the second signal is a message; through presetting a mapping relationship between the at least one sequence in the first signal and a message size in the signals, enabling the receiving end to obtain the message size based on the preset mapping relationship between the at least one sequence in the first signal and the message size in the signals. Because the receiving end does not need to perform a blind test on each possible message size, an amount of computation and power consumption are reduced, and a cost and the power consumption is reduced; In addition, time frequency resources occupied by the first signal are evenly scattered in time frequency resources occupied by the second signal so that a sending end does not need to send a corresponding RS signal for the message, reducing a system overhead. |
