Abstract
Systems and techniques for managing the use of almost blank subframes in wireless communication systems. Base stations in a wireless network monitor load information affecting network nodes. Load information may be in the form of load metric information. The load information may be exchanged between system elements, and an almost blank subframe proportioning may be updated by one or more of the base stations, and information relating to the updated proportioning. The updated almost blank subframe proportioning may be used in scheduling and load metric calculation, as well as almost blank subframe patterning. Updating of almost blank subframe information and load metric information may be performed iteratively.
