Abstract: This application provides a synchronization signal transmission method and a communications apparatus. The synchronization signal transmission method and the communications apparatus are applied to the communications field. In the synchronization signal transmission method, a synchronization signal generated and sent by a network device may include a first sequence and a second sequence. The first sequence is a first complex sequence or a sequence obtained based on the first complex sequence. The second sequence is a sequence obtained based on the first complex sequence, and the second sequence is different from the first sequence. Because a correlation processing result between the first sequence and the second sequence is still a complex sequence, there is a good correlation property, so that a terminal device can obtain a relatively sharp correlation peak when synchronizing with the network device based on the synchronization signal, thereby effectively shortening duration required for synchronization.

Abstract: A network device sends downlink control information to a first terminal device. The downlink control information includes: time domain resource information, where the time domain resource is a time domain resource on which a first data channel is located; and frequency domain resource information, where the frequency domain resources are a frequency domain resource on which the first data channel is located and a frequency domain resource on which a second data channel is located. The second data channel is located on a time domain resource different from the time domain resource on which the first data channel is located. The first terminal device receives, on the determined time domain resource and frequency domain resource, a signal that is located on the first data channel and that is from the network device.

Abstract: The present disclosure discloses a data transmission method, a device, and a system, relates to the communications field, and can resolve a prior-art problem that a receive end cannot correctly receive data because a starting moment of sending information on a license-exempt spectrum cannot be determined. A specific solution is as follows: A first device detects first information of a first serving cell in a preset time period of a first subframe on a first time resource or a first time set of a subframe on a first time resource, determines a starting position of a second time resource according to the first information, and detects second information of the first serving cell in a second time set of a subframe on the second time resource. The present disclosure is used for data transmission.
