5. A communication method implemented by a terminal, comprising:
receiving
information associated with a signal transmitted to an apparatus other than the terminal, in MU-MIMO (MultiUser-Multiple Input Multiple Output) and
a reference signal from a base station;
estimating interference from the signal transmitted to the apparatus other than the terminal to a signal transmitted to the terminal, based on the information associated with the signal transmitted to the apparatus other than the terminal and the reference signal;
suppressing the interference and receiving a data signal from the base station; and
estimating the interference from the signal transmitted to the apparatus other than the terminal to the signal transmitted to the terminal, based on the reference signal that is not precoded.
