Abstract

A channel estimation method comprising when it is determined that in-band SRSs are required to be transmitted acquiring the number of transmitting antenna ports and the number of layers of the currently transmitted DMRSs; calculating the difference of the number of the transmitting antenna ports and the number of layers of the currently transmitted DMRSs and using the difference as the number of in-band SRSs that are required to be transmitted; transmitting in-band SRSs to a receiving-end device according to the number of in-band SRSs that are required to be transmitted to enable the receiving-end device to perform channel estimation according to the currently transmitted DMRSs and the received in-band SRSs. A channel estimation method comprising receiving in-band SRSs transmitted from a transmitting-end device the number of the in-band SRSs being the difference of the number of transmission antenna ports on the transmitting-end device and the number of layers of the currently transmitted DMRSs; performing channel estimation according to the received in-band SRSs and the currently transmitted DMRSs. A transmitting-end device a receiving-end device and a communication system are also provided.
