Patent number: 9326152Abstract: In certain embodiments, a cellular wireless communications network has clusters, each cluster having a plurality of cells and a cluster-level controller that dynamically divides the cluster into non-interfering sub-clusters for each resource allocation unit (e.g., physical resource block). Each sub-cluster has one or more cells that transmit to a single user in the cluster for the resource allocation unit, and at least one sub-cluster has at least two cells that transmit to a single user for the resource allocation unit using a distributed diversity mode of communication in which the at least two cells transmit the same data to the single user. The controller divides the cluster into sub-clusters based on determinations of whether users in the cluster are susceptible to interference from non-serving cells in the cluster. By assigning potentially interfering, non-serving cells to the sub-cluster for a user, those non-serving cells are eliminated as sources of interference.Type: GrantFiled: November 4, 2014Date of Patent: April 26, 2016Assignee: Alcatel LucentInventors: Simon Yiu, Doru Calin
