Abstract:
1. A method of configuring a self organizing wireless network (SON) comprising the steps of: determining a fractional time reuse (FTR) factor based on a number of transmission nodes having an overlapping coverage area; determining long-term scheduling restrictions based on the FTR factor for scheduling transmission time intervals (TTIs) of each of the transmission nodes, the long-term scheduling assigning a unique subset of TTIs to each of the transmission nodes so that transmissions according to different long term scheduling restrictions are staggered in time; and assigning each of the determined long-term scheduling restrictions to a respective one of the transmission nodes for use in scheduling the transmission times of user equipments (UEs) served by the transmission nodes on any of the transmission frequencies used by the transmission nodes; wherein the long-term scheduling restrictions of the transmission nodes are enforced for UEs classified to be at an edge of a transmission node's coverage area; and wherein the long-term scheduling restrictions of the transmission nodes are not enforced for UEs classified to be at a center of a transmission node's coverage area.
