METHOD FOR TRANSMITTING SIGNALS USING BLIND INTERFERENCE ALIGNMENT SCHEME

摘要

Disclosed is a method for transmitting a signal by using a blind interference alignment scheme. The signal transmission method of a base station comprises the following steps: determining the number of transmission symbol vectors for each of two or more users supported by a base station in an extent of satisfying a predetermined symbol extension length; determining mode switching patterns for each of the users so that a sum rate of wireless communications systems can be maximum on the basis of the number of the transmission symbol vectors; and transmitting the symbol vectors including data streams for the users to each of the users according to the mode switching patterns.
