摘要:
Existing criteria for analyzing radio link failure conditions may not satisfactorily address the conditions between cells that support cooperative resource coordination. Generally, when the UE declares radio link failure, the UE discontinues communication with a serving base station and searches for a new base station. When the UE lies in a region with severe interference, where the interference is coordinated between base stations by the interfering cell yielding part of its resources, the UE measurements for determining radio link failure (RLF) may vary considerably, depending on whether the measured resources were yielded by the interfering cell. When the UE measures resources which were not yielded by the interfering cell, the UE can erroneously declare RLF (e.g., due to high interference), although the UE can still access the serving cell using resources yielded by the interfering cell. Accordingly, disclosed are aspects for determining RLF based by accounting for cooperative resource coordination employing yielded resources.
