Abstract
We propose an opportunistic scheduling method to achieve DoF (degrees of freedom) gain by BIA (blind interference alignment) in block fading K-user 2 × 1 MISO broadcast channel. The optimal scheduling method is obtained by solving a general model of linear integer program. All the users are divided into user pairs to form a 2-user 2 × 1 BIA. Each pair has the same opportunity to be scheduled. When K ≥ 10, the expectation of the achieved DoF can be very close to 4/3.
