Abstract: In some aspects, the disclosure is directed to methods and systems for dense small cell deployment. In one or more embodiments, a plurality of small cells is grouped into a first group of small cells having a first power level and a second group of small cells having a second power level. In one or more embodiments, each power level in the first set of power levels is greater than each power level in the second set of power levels. In one or more embodiments, the small cells of the first group performs frequency domain inter-cell interference coordination (ICIC) between the small cells of the first group. In one or more embodiments, the small cells of the second group performs time domain ICIC with the small cells in the first group. In one or more embodiments, the small cells of the first group use a same almost blank subframe (ABS) pattern.

Abstract translation: 在一些方面，本公开涉及用于密集小细胞部署的方法和系统。 在一个或多个实施例中，多个小单元被分组成具有第一功率电平的第一组小单元和具有第二功率电平的第二组小单元。 在一个或多个实施例中，第一组功率电平中的每个功率电平大于第二组功率电平中的每个功率电平。 在一个或多个实施例中，第一组的小单元在第一组的小单元之间执行频域小区间干扰协调（ICIC）。 在一个或多个实施例中，第二组的小单元使用第一组中的小单元执行时域ICIC。 在一个或多个实施例中，第一组的小单元使用相同的几乎空白的子帧（ABS）模式。
