Abstract: A method of transmitting a narrow-band orthogonal frequency division multiplexing signal, comprising: determining a spectrum resource of a narrow-band orthogonal frequency division multiplexing system in a bandwidth of a long-term evolution (LTE) system sharing the bandwidth with the narrow-band orthogonal frequency division multiplexing system according to a resource selection strategy; and transmitting the narrow-band orthogonal frequency division multiplexing signal on the determined spectrum resource of the narrow-band orthogonal frequency division multiplexing system. The solution enables transmission of a narrow-band orthogonal frequency division multiplexing signal in a bandwidth of an LTE system, thus facilitating signal detection and cost reduction of a terminal served by the barrow-band orthogonal frequency division multiplexing system, and also reducing interference between the LTE system and the narrow-band orthogonal frequency division multiplexing system.
