摘要
Method and apparatus for downlink (DL) channel estimation in massive MIMO are provided. A base station (BS) support massive MIMO may select a dictionary for a user equipment (UE) in its cell and transmit information for constructing the dictionary to the UE. The UE constructs the dictionary based on the information received and performs compressed sensing (CS) -based DL channel estimation for the BS. The UE also sends feedback information to the BS, which include information that is useful for determination of the dictionary by the BS.
