Abstract
Systems and methods for managing and/or improving interference in cells may be provided. For example, in embodiments, a partial-band Almost Blank Subframe (PB-ABS) subframe and/or a spatial Almost Blank Subframe (SABS) may be provided and/or used for coordinating communication with in networks with smaller and larger cells (e.g. pico or macro cells). For example, a PB-ABS may provide a dimension (e.g. frequency) that may be used to define a region and/or particular resources (e.g. resource blocks) reserved for pico cell operations or transmissions and a region or other resources (e.g. not those reserved for pico cell operations) available for macro cell operations or transmissions. Additionally, based on beam parameters (e.g. associated with cell partitioning), SABS may offer an additional dimension (e.g. spatial) that may be used to prevent transmission in a particular spatial direction.
