Abstract: This application relates to the mobile communications field, and in particular, to a random access technology in a wireless communications system. This application provides a method for sending a random access preamble sequence, an apparatus, and a system. In this solution, a terminal device obtains a cyclic shift value that satisfies a high-speed movement scenario and sends a random access preamble sequence corresponding to the cyclic shift value. Impact brought by the high-speed movement scenario is considered when the random access preamble sequence is determined, thereby avoiding interference between terminal devices in the high-speed scenario.

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: In a system and method of control channel transmission in the communications field, REs, except those used for transmitting a DMRS, are grouped in each physical resource block pair of L physical resource block pairs. The L physical resource block pairs are determined to be used to transmit a control channel into N eREGs. The number of valid REs are calculated except other overheads in each eREG of the N eREGs. Each of the eCCEs are mapped onto M eREGs according to the number of valid REs included in each eREG of the N eREGs of each physical resource block pair. The eCCE is sent in the REs included in the eREG.
