Abstract
A cell informs surrounding cells about an orthogonal resource allocation strategy of the informing cell so as to induce cooperative behavior among the cells. The informing cell also receives resource allocation strategies from the surrounding cells. Each cell allocates its orthogonal resources according to the mutually exchanged information. The result is to reduce interference in the system. For example, a BS informs other cells on which clusters it generates a small interference, e.g., close UEs concentrated into a particular cluster, and indicate that to its neighbors. Other cells would concentrate UEs which are on the edge to the indicating cell exactly in this cluster. This would mean an “overload invitation”, i.e. inviting the neighbors to produce overload on a particular cluster. If a cell sends an overload invitation on a sufficiently large cluster, this will automatically reduce the interference in the other clusters.
