Abstract: This application provides a transmission method and apparatus. The method includes: A terminal sends a random access preamble to a base station at a first transmit power, and sends a PUSCH to the base station at a second transmit power, where power deviation between the first transmit power and the second transmit power is indicated to the base station by indication information; and the terminal receives a random access response or a contention resolution message from the base station. Implementing this application can improve an existing random access procedure, so that the random access procedure is adapted to scenario requirements such as low delay, high reliability, and large-scale terminal access.
