Abstract
The present disclosure provides a method () in a network device for channel estimation. The method () includes: transmitting () 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; receiving () from the terminal device L*N precoded DMRSs; estimating () 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 determining () the uplink channel from the equivalent channel based on the N precoders.
