| Zusammenfassung: | The present application provides a signal transmission method and apparatus, which are beneficial for enhancing uplink coverage of a terminal device and improving system performance. The method comprises: before a terminal device performs physical random access channel (PRACH) transmission, determining whether an upcoming PRACH transmission is a first PRACH transmission; when the upcoming PRACH transmission is not the first PRACH transmission, the terminal device determining whether the upcoming PRACH transmission is a first multiple-instance PRACH transmission; and when the upcoming PRACH transmission is a first multiple-instance PRACH transmission, the terminal device initiating multiple PRACH transmissions to a network device on the basis of the number of transmissions of the upcoming PRACH transmission and transmit power of the upcoming PRACH transmission, wherein the number of transmissions of the upcoming PRACH transmission and the transmit power of the upcoming PRACH transmission are determined by the |
