- Abstract
- Provided is a frame transmission method of interference alignment (IA) and controlling, the method including calculating a channel matrix of a basic service set (BSS) by measuring channel information between an access point and a user terminal, performing singular value decomposition (SVD) based on the calculated channel matrix, selecting a beamforming vector in consideration of an interference amount associated with another access point based on the SVD performed by the channel matrix, and calculating a leakage interference (LIF) value based on the selected beamforming vector.
