Abstract: Embodiments of this application provide an information transmission method and a device. The method includes: sending, by a first device, M signals to a second device through N ports, where N and M are integers, and M≥N≥2; and receiving, by the first device, measurement information sent by the second device, where the measurement information is determined by the second device based on the M signals, and the measurement information is used to indicate a relationship between the N ports. Therefore, in the embodiments of this application, the relationship between the ports is determined by using characteristics of the ports on a side of the second device, so that the first device can relatively accurately determine the relationship between the ports, and the first device can perform appropriate communication management on the plurality of ports. This improves performance of transmission between the first device and the second device.
