    摘要: An embodiment of the present invention provides a method of using differential precoding feedback for correlated channels, comprising, transmitting by a mobile station (MS) as feedback an index angle for a differential discrete Fourier transform (DFT) codeword corresponding to a shift of a dominant beam represented by a base codeword, where the feedback corresponds to a precoding vector V(t)=Q({circumflex over (θ)}) for index angle θ, where Q  ( θ ^ ) = [ 1  j   2   π   m / 32  j   4   π   m / 32  j   6   π   m / 32 ] and m=−16 cos({circumflex over (θ)}).

    摘要: A method is disclosed to eliminate inter-cluster interference of user equipment located at the edge of a cluster of cells. The method operates by employing fractional frequency reuse (FFR) principles on clusters or combinations of cells in a wireless neighborhood, in which base stations in the cells coordinate their operations in a scheme known as coordinated multi-point transmission (CoMP). By using the FFR principles to single out edge users of the CoMP cluster, the method mitigates interference and increases throughput for the edge users.

    摘要: Improved methods and apparatuses are provided to address a potential “hidden beam problem” in wireless communication systems employing smart antennas. The improved methods and apparatuses utilize complementary beamforming (CBF) techniques, such as, for example, Subspace Complementary Beamforming (SCBF), Complementary Superposition Beamforming (CSBF) and/or Single Beam Complementary Beamforming (SBCBF) techniques.
