  • Abstract
    While the outer-bound of sum degrees of freedom (DoF) of 3-user interference channel is known, the entire DoF region is still unknown in terms of both outer-bound and achievable region. In this paper, we first give the outer-bound of DoF region. Then, we present a linear beamforming scheme based on interference alignment chain whose achievable DoF region is the same as the outer bound, with the consideration of integer DoF only.
