METHOD AND APPARATUS FOR OPPORTUNISTIC INTERFERENCE ALIGNMENT (OIA) IN MULTI-USER MULTIPLE-INPUT MULTIPLE-OUTPUT (MU-MIMO) TRANSMISSION

摘要

A method and apparatus for opportunistic interference alignment (OIA) in multi-user multiple-input multiple-output (MU-MIMO) transmission, the method including broadcasting a random beam, receiving, from a terminal, feedback information determined based on the random beam, selecting at least one terminal to which data is to be transmitted from among terminals based on the feedback information, adjusting a transmission power based on the feedback information, and transmitting data to the selected at least one terminal based on the adjusted transmission power.
