摘要： Embodiments of the present invention provide a synchronization method, a base station, and user equipment. The method includes: completing, by an unlicensed-spectrum base station, preemption of a radio channel of an unlicensed spectrum at a first time point; determining, by the unlicensed-spectrum base station, a second time point, where the second time point is a subframe boundary at which the base station starts to send an effective subframe; intensively sending, by the unlicensed-spectrum base station, synchronization signals in a first time period between the first time point and the second time point, so that user equipment UE completes uplink synchronization in the first time period; and starting, by the base station, to send the effective subframe at the second time point. According to the embodiments of the present invention, after preempting the radio channel of the unlicensed spectrum, the unlicensed-spectrum base station intensively sends the synchronization signal. Therefore, the UE completes synchronization with an unlicensed-spectrum cell or base station in a short time, to start to perform data transmission by using the unlicensed spectrum as early as possible, thereby improving utilization of an unlicensed spectrum resource.

摘要： This application provides a communication method and a communication apparatus, so that sidelink signaling can be used for transmission of AS configuration information. Specifically, a first terminal device obtains a source identifier allocated to groupcast communication by a second terminal device, where the groupcast communication is communication for a target group, and the first terminal device and the second terminal device belong to the target group. A V2X layer of the first terminal device generates first sidelink signaling, and sends the first sidelink signaling, a first identifier, and a group identifier to an AS of the first terminal device, where the first identifier is a source identifier allocated to the groupcast communication by the first terminal device, and the group identifier is used to identify the target group. The AS sends the first sidelink signaling by using the first identifier as a source identifier and using the group identifier as a destination identifier.
