The embodiment of the invention provides an information transmission method and equipment. The method comprises the following steps that: first equipment transmits M signals to second equipment through N ports, wherein N and M are integers, and M>=N>=2; and the first equipment receives measurement information transmitted by the second equipment, wherein the measurement information is determined bythe second equipment according to the M signals, and used for indicating a relationship among the N ports. The relationship among the ports is determined by means of the characteristics of the portson a second equipment side in the embodiment of the invention, so that the first equipment can be enabled to accurately determine the relationship among the ports and perform reasonable communicationmanagement on the plurality of ports, and the transmission performance between the first equipment and the second equipment is improved.
