The invention relates to the field of
wireless communication technology, in particular to a method, device and
system for transmitting reference signals, and aims to solve the problems in the prior art that
estimation of a vertical dimension channel can not be supported and 3D beam forming can not be supported. The method provided by the embodiment of the invention comprises the following steps: a network side determines a
subframe for bearing reference signals, determines a
pilot frequency port for the reference signals, and also sends the reference signals which are allocated in the
pilot frequency port in the
subframe, wherein the
pilot frequency port at least comprises a row of horizontal dimension pilot frequency ports and a
list of vertical dimension pilot frequency ports, reference signals allocated in the horizontal dimension pilot frequency ports are horizontal dimension reference signals, and reference signals allocated in the vertical dimension pilot frequency ports are vertical dimension reference signals. According to the method, device and
system, provided by the embodiment of the invention, since the vertical dimension reference signals can be sent out directly, the channel
estimation of the vertical dimension pilot frequency ports can be achieved, and the dynamic 3D beam forming technology can be achieved.
