1. A pico base station, comprising:
- a central processing unit (CPU) configured to;
generate interference distribution information for user equipment (UE) scheduling based on at least one power allocation pattern of a plurality of physical resource blocks (PRBs) associated with at least one macro base station; and
schedule at least one UE associated with the pico base station based on the interference distribution information.

Abstract
Embodiments described herein are directed to a power control scheme for Long Term Evolution Advanced (LTE-A) heterogeneous networks to reduce the interference from macro base stations (BS) to pico user equipment (UE). The embodiments described herein may be used to develop LTE-A heterogeneous networks to balance the achievable throughput between macro and pico UEs and may thereby improve the overall system performance.
