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 message transmission method and device relating to the field of communications technologies are described that improve an anti-interference capability in message transmission. The method includes generating a scrambling code according to a scrambling code initialization seed, wherein the scrambling code initialization seed meets the following expression: cinit=R·2a7+P·(nf modk+1)·2b7 and then scrambling a message according to the scrambling code. The method further includes sending the scrambled message to a terminal on a physical downlink shared channel. Because the first time parameter has different values at at least two different moments, scrambling codes determined at the at least two corresponding different moments are different. Therefore, a possibility at which the base station uses a same scrambling code to scramble a same system message repeatedly in a time period is reduced, so that an anti-interference capability in system message transmission is improved.

Abstract: A method for scheduling resources is disclosed herein. A terminal device receives a downlink control information (DCI) indication sent by a network device. The DCI is used to indicate a first resource, and the first resource is a time-frequency resource for a narrowband physical uplink shared channel (NPUSCH) format 2 transmission. The NPUSCH format 2 is used to bear downlink hybrid automatic repeat request-acknowledgment (HARQ-ACK) feedback information. The terminal device determines the first resource according to the DCI, and sends a scheduling request to the network device on the first resource.

Abstract: Example signal transmission methods and apparatus are described. One example method includes generating a first signal by a network device, where the first signal is used to indicate to a terminal device whether there is paging scheduling information on a first paging occasion. The network device determines a first resource based on at least one of a paging configuration parameter, a first parameter set, a terminal device identifier, or a terminal identification code. The network device sends the first signal to the terminal device on the first resource. The signal transmission methods, network device, and terminal device in the embodiments of this application enable the terminal device to determine, based on the first signal, whether to listen on a downlink control channel, reducing power consumption of the terminal device.
