Abstract: The present invention provides a signal sending apparatus, a signal detection apparatus, a signal sending and detection system, a signal sending method, and a signal detection method. The apparatus determines a time unit that is in each time window and that is used to transmit a synchronization signal, and transmits the synchronization signal in the determined time unit in each time window. Therefore, a synchronization signal is always located in a time unit that has a fixed location in each time window, so that a device at a receive end needs to perform detection only in a fixed time unit in each time window, thereby reducing complexity of designing and detecting the synchronization signal.

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 using 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.
