Abstract:
A method and apparatus of transmitting data in a coordinated multi-cell wireless communication system is provided. A base station receives information about beam-forming vectors, aligned with a channel to a user equipment placed in a neighbor cell, and about nulling beam-forming vectors for the channel to the user equipment from the neighbor cell, determines a transmission beam-forming vector based on the information, and transmits data to the user equipment using the transmission beam-forming vector.
