ADAPTATION OF ENHANCED INTER-CELL INTERFERENCE COORDINATION CONFIGURATION
First Claim
1. A method for adapting a long-term almost blank subframe (ABS) configuration of a cell, the method comprising:
- determining, by the cell, a current neighbor cell deployment state; and
adapting a long-term downlink ABS configuration of the cell based on the current neighbor cell deployment state.

Abstract
In a wireless communication system, a cell may perform a method for adapting a long-term or short-term almost blank subframe (ABS) configuration, including determining, by the cell, a current neighbor cell deployment state, and adapting a long-term downlink ABS configuration of the cell based on the current neighbor cell deployment state. The current neighbor cell deployment state may include, for example, a number of neighbor cells, signal strengths of the neighbor cells, or a number of users being served in Cell Range Expansion (CRE), which may be determined using a Neighbor Listen module, receiving measurement reports from UEs, or receiving reports from small cell neighbors via a backhaul. Adapting the long-term downlink ABS configuration of the cell may include increasing a proportion of ABS-vacated resources in proportion to an change in neighbor cell deployment density, increasing neighbor cell signal strength, or increasing number of users served in CRE by neighbor cells.
