Claim 0:
1. A network device for channel estimation, the network device comprising one or more processors and one or more memories comprising instructions executable by the processors, whereby the network device is configured to:
transmit, to a terminal device, an instruction to precode each of a number, L, of DeModulation Reference Signals (DMRSs) using a number, N, of linearly independent precoders, respectively;
receive, from the terminal device, L*N precoded DMRSs;
estimate an equivalent channel associated with an uplink channel from the terminal device to the network device based on one or more of the L*N precoded DMRSs; and
determine the uplink channel from the equivalent channel based on the N precoders.
