Abstract: An information transmission method, is provided, including, a terminal determines attribute information of uplink information based on a beam identifier, and sends the uplink information to a network side device based on the attribute information. After receiving the uplink information, the network side device determines the beam identifier based on the uplink information. In this process, the terminal implicitly indicates beam IDs of different selected beams by using attribute information of reported uplink information. Different beams correspond to different attribute information of the uplink information. In other words, each beam corresponds to specific attribute information of the uplink information. Implicitly indicating a beam ID to the network side device reduces LTE standardization complexity and reduces signaling overheads.

Abstract: This application provides a communication method. The communication method includes: A first device sends indication information, where the indication information is used to indicate whether the first device sends a first synchronization signal block in a synchronization slot of a sidelink, and the synchronization slot is used to transmit a synchronization signal block; and the first device sends first data in the synchronization slot of the sidelink. Because the first device indicates a sending behavior of the first device in the synchronization slot before sending the first data, a receiver may determine a processing manner of the receiver in the synchronization slot based on the indication information.
