Abstract: A switch circuit of a converter includes three switch units. A first switch unit includes a first switch device, a second switch device, a third switch device, and a fourth switch device that are connected in series. A second switch unit includes a fifth switch device and a sixth switch device that are connected in series. A third switch unit includes a seventh switch device and an eighth switch device that are connected in series. When the first switch device and the fifth switch device are switched on, the seventh switch is controlled to be switched on. When the fourth switch device and the sixth switch device are switched on, the eighth switch device is controlled to be switched on, thereby effectively reducing a conduction loss of the converter.

Abstract: In a time deviation determining method, a terminal determines an uplink timing advance between the terminal and a base station; determines a one-way transmission delay based on the uplink timing advance; and determines a clock time deviation between the terminal and the base station based on the one-way transmission delay, a time difference between a base-station clock time of a system frame in two system frames and a terminal clock time of a following system frame in the two system frames, and a time difference between the two system frames. In the solution provided in this application, the clock deviation between the terminal and the base station can be determined more flexibly and accurately. In addition, signaling interaction between the terminal and the base station is reduced, and network resources are saved.

Abstract: A synchronous communication method is provided. The method includes: obtaining, by a first terminal, first configuration information, where the first configuration information includes a first parameter; determining, by the first terminal according to a global navigation satellite system (GNSS) clock, a transmission timeslot corresponding to a current moment in a device-to-device (D2D) communications system; determining, by the first terminal according to the transmission timeslot and the first parameter, whether the current moment is a synchronization-information-sending moment; if the current moment is the synchronization-information-sending moment, sending, by the first terminal, sidelink synchronization information at the synchronization-information-sending moment, where the sidelink synchronization information carries indication information, the sidelink synchronization information is used to synchronize a second terminal with the first terminal, and the indication information is used to indicate, to the second terminal, that the first terminal is a synchronization source that uses the GNSS clock.

Abstract: This application provides a communication method and device. The method includes: determining, by a first device, a first synchronization signal, where the first synchronization signal is used by a second device for symbol timing alignment and frequency synchronization; and sending, by the first device, the first synchronization signal on each group of subcarriers of M groups of subcarriers, where M is a positive integer greater than or equal to 2. According to the communication method in this application, the first device sends the first synchronization signal on each group of subcarriers of a plurality of groups of subcarriers, so that the second device can select, based on a reception capability of the second device, an appropriate bandwidth to receive the first synchronization signal. In this way, a device with wideband reception performance and a device with narrowband reception performance can be supported.
