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.
