ABSTRACT:
A novel soft fractional frequency reuse (FFR) technique is disclosed. The novel FFR technique includes reuse partition and power restriction, dynamic user grouping, channel quality indicator feedback based on reuse, and a user group-based interference aware scheduler. The FFR technique reduces co-channel interference for cell edge users.
