Method in a scheduler for reducing inter-cell interference

A scheduler capable of controlling a set of shared radio resources in a cellular radio system, the scheduler comprising:

• means for assigning cell specific resource priority weights (RPW) to the different radio resources available in a cell, said assignment differs from the assignment of the same radio resources in at least one neighboring cell;
• means for combining the cell specific resource priority weights with channel quality indication reports (CQI) from the users to form weighted quality indexes (WCQI) for the radio resources that are available to the scheduler;
• means for utilizing the weighted quality indexes for selection of radio resources;
• and
• means for transmitting data from or receiving data at a base station associated with the first cell using the selected radio resources.

A scheduler capable of controlling a set of shared radio resources in a cellular radio system, wherein the scheduler comprises:

• means for assigning cell specific resource priority weights (RPW) to the different radio resources available in a cell, said assignment differs from the assignment of the same radio resources in at least one neighboring cell;
• means for categorizing the radio resources into resource priority classes including “preferred,” “allowed,” and “prohibited” classes;
• means for utilizing the resource priority classes for selection of radio resources, wherein resources of the “preferred” priority class are used first, resources of the “allowed” priority class are used only when no more unused resources of the “preferred” priority class exist, and resources of the “prohibited” priority class are never used;
• and
• means for transmitting data from or receiving data at a base station associated with the first cell using the selected radio resources.
