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

摘要

A method and apparatus for opportunistic interference alignment (OIA) in single-user multiple-input multiple-output (SU-MIMO) transmission, the method including selecting an interference space, broadcasting information on the selected interference space, selecting a user terminal to be assigned a transmission opportunity for each subchannel based on leakage of interference (LIF) information when a request to send (RTS) message including the LIF information is received from at least one user terminal, and transmitting data to the selected user terminal.
