The embodiment of the invention relates to the technical field of wireless communication, particularly relates to a pilot signal transmission method, a signal measuring method, a signal measuring system, a piece of pilot signal transmission equipment and a piece of signal measuring equipment, and aims to solve the problem that each antenna unit transmits one pilot signal to result in very low transmission power of each antenna unit, and user equipment is high in complexity when the number of the antenna units is large in the prior art. The pilot signal transmission method of the embodiment of the invention comprises the step in which network side equipment sends determined CSI feedback configurations to user equipment, wherein one CSI feedback configuration corresponds to one CSI-RS resource, and a pilot signal corresponding to each port of one CSI-RS resource is sent through a set of antenna units corresponding to the port. By adopting the scheme provided by the embodiment of the invention, the transmission power of the antenna units can be increased to enable the user equipment to carry out signal measurement correctly, the performance of data transmission is improved, and the complexity of the user equipment is reduced when the number of the antenna units is large.
