Zusammenfassung:The invention provides a signal transmission method and device, which are favorable for enhancing the uplink coverage range of terminal equipment and improving the system performance. The method comprises the following steps: before performing physical random access channel (PRACH) transmission, the terminal equipment judges whether the PRACH transmission to be performed is the first PRACH transmission or not; under the condition that the upcoming PRACH transmission is not the first-time PRACH transmission, the terminal equipment judges whether the upcoming PRACH transmission is the first-time multi-time PRACH transmission or not; under the condition that the upcoming PRACH transmission is the first multiple PRACH transmission, the terminal device initiates multiple PRACH transmissions to the network device based on the number of transmission times of the upcoming PRACH transmission and the transmitting power of the upcoming PRACH transmission, the number of transmission times of the upcoming PRACH transmissi
