Title: APPARATUS AND METHOD FOR INTERFERENCE MITIGATION IN A WIRELESS COMMUNICATION SYSTEM
Abstract:
An apparatus and method for mitigating inter-cell interference in a macro Base Station (BS) of a wireless communication system having at least one femto cell are provided. The method includes restricting the use of at least one code among at least one available code when forming a beam by resource block, constructing a codebook set for each resource block, when feedback information is received from at least one Mobile Station (MS), allocating a resource to the MS in consideration of the feedback information, determining a weight for forming a beam to the MS in consideration of the codebook set for each resource block and the resource allocated to the MS, and forming the beam to the MS using the weight.
