Methods and Systems for Almost Blank Subframe (ABS) Pattern Selection for Small Cells
Abstract:
Embodiments provide systems and methods for selecting almost-blank sub-frames (ABSs) in wireless networks. ABSs may be utilized as part of enhanced inter-cell interference cancellation (eICIC). In an embodiment, an ABS pattern is selected in a distributed fashion without use of a direct interface between neighboring base stations. Embodiments operate with a hybrid self-organizing network (SON) that includes a centralized self-organizing network (cSON) unit and a distributed self-organizing network (dSON) unit. The cSON may provide the dSON with information about a plurality of ABS patterns, and the dSON may utilize the information received from the cSON to select an ABS pattern from the plurality of ABS patterns. In some embodiments, a base station may select neighboring base stations to perform eICIC based on a reference signal received power (RSRP).
