Abstract
A communication method for at least one mobile station that includes a target mobile station that performs a Cooperative Multi-Point (CoMP) communication with at least two base stations, is provided. The communication method includes determining a beamforming vector used by the at least two base stations based on channel vectors and at least one channel matrix such that a signal-to-leakage-plus-noise-ratio (SLNR) for a target antenna from among antennas of a target mobile station is maximized. A Cholesky factorization may be used to determine an optimal beamforming vector with a low complexity.
