Abstract
The invention discloses a channel estimation method, a channel estimation device and a channel estimation system. Inband sounding reference signals (SRS) are transmitted to receiving equipment by taking a difference between the number of transmitting antenna ports and the layer number of a currently transmitted demodulation reference signal as the number of the inband SRSs to be transmitted, and the inband SRSs are combined with the DMRS for channel estimation at the receiving equipment. Compared with the prior art, the invention can estimate integral channel information with lower overhead.
