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.
