Abstract: This application provides a synchronization method and an apparatus. The method includes: mapping, by first UE, to-be-transmitted data and a first sequence to a symbol of a first time unit, to obtain a first signal, where the first sequence is mapped to at least one symbol at a non-starting location of the first time unit; and sending, by the first UE, the first signal to second UE. The second UE receives the first signal, obtains the first sequence, and performs synchronization on the first signal based on the first sequence.

Abstract: A laser includes a substrate and a resonant cavity. In addition to an active gain region, a first phase shift region, an optical branching region, and N reflective mode selection regions, the resonant cavity further includes a highly reflective surface, where a reflectivity of the highly reflective surface is greater than reflectivities of the N reflective mode selection regions, so that laser beams are output from the N reflective mode selection regions. Because the laser naturally includes at least two reflective mode selection regions, at least two laser beams are output. According to the laser provided by the embodiments of the present invention, one laser can output two laser beams or even multiple laser beams; therefore, laser beam generation efficiency is high and average costs for generating a single laser beam are accordingly reduced.

Abstract: This application provides a communication method and apparatus, and relates to the field of wireless communication. A first node may send first configuration information on a first frequency hopping channel (S501), to configure a communication link between at least two second nodes. The communication link includes a direct link between the at least two second nodes, and the first node is a master node of at least one second node in the two second nodes corresponding to the direct link. In the foregoing method, the first node may configure the communication link between the at least two second nodes. Therefore, a conflict between a resource of the direct link and a resource of a master and slave communication link can be avoided, thereby improving communication performance.

Abstract: In an advertising method, a first device generates a first signal, where a modulation type of the first signal is PSK modulation. The first signal sequentially includes a sequence part, a first part, and a second part. The sequence part includes at least one of a predefined sequence, a predefined signal, a preconfigured sequence, and a preconfigured signal. The first part includes first control information encoded by using a polar code. The second part includes first advertisement information. The first device sends the first signal on a first advertisement dedicated frequency hopping channel.

Abstract: First information is sent using a multicast resource to a communication apparatus group that includes at least two communication apparatuses. Feedback information is detected, on a shared unified time-frequency resource, from at least one communication apparatus in the communication apparatus group, where the feedback information indicates that there is at least one communication apparatus in the group that fails to correctly receive the first information, where the time-frequency resource is a feedback resource used by all communication apparatus in the communication apparatus group to send feedback information.

Abstract: This application relates to a scheduling method, an apparatus, and a system. A first communications apparatus sends first signaling on a first resource, where the first signaling is used to indicate N communications apparatuses. The first communications apparatus sends second signaling on a second resource, where the second signaling is used to schedule the N communications apparatuses to send or receive first data, and the first resource has an association relationship with the second resource. In addition, the first resource has the association relationship with the second resource. In this case, a receive end of the first signaling and the second signaling may determine the second resource after determining the first resource, so that the second signaling is only detected on the second resource, and blind detection does not need to be performed on too many resources.
