摘要： A media access control method of a wireless sensor network (WSN) is provided. The media access control method includes first sensor nodes, existing in a non-overlapping area where clusters do not overlap, media-accessing with a Time Division Multiple Access (TDMA) method and communicating with a Cluster head (CH) in a first section. Further, and the method includes second sensor nodes, existing in an overlapping area where the clusters overlap, media-accessing with a contention-based method and communicating with the CH in a second section. Because communication between nodes of the non-overlapping area where the clusters do not overlap, uses a reservation-based TDMA method, collision between nodes can be prevented, and because communication between nodes of the overlapping area where the clusters overlap, uses a contention-based CSMA/CA method, interference between neighboring clusters can be prevented.

摘要： 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.
