Abstract

A method and system for allocating PDCCH resources in a wireless communication system are disclosed. According to one aspect, a method includes detecting at a first base station a condition of inter-cell interference, ICI, between a first cell and a neighboring cell, indicating that the first cell is in a coordination need state. The method includes generating at the first base station serving the first cell a request to lower a first PDCCH load of the neighboring cell to reduce the ICI between the first cell and the neighboring cell, a PDCCH load of a cell being defined as a ratio of used resource elements to total available resource elements within the cell.
