<p>A method and controller for reducing inter-cell interference within a Coordinated Multi-Point (CoMP) cellular network architecture. Multiple CoMP cells in the network architecture are grouped into a number of mutually exclusive subsets. The CoMP cells in each subset are sufficiently separated from each other geographically so that no inter-cell interference occurs among them, and thus they can be scheduled independently. Each subset then takes turn scheduling in a certain order. As each subset schedules its transmissions, it avoids causing interference to subsets that have already scheduled, and then passes sufficient information to the remaining subsets so that the same interference avoidance measures can be taken. The scheduling and passing of the information is preferably performed before the data transmission phase, which occurs once every Transmission Time Interval (TTI).</p> |
