US 2010/0142415 A1 · APPARATUS AND METHOD FOR SCHEDULING IN A RELAY SYSTEM

Abstract

An apparatus and a method for scheduling and a power control of a relay system that is capable of stable operation an environment where sufficient isolation between antennas is not ensured. The apparatus includes a scheduler for allocating resources to a zone not experiencing inter-antenna interference in an initial resource allocation, classifying users based on vulnerability to the interference, and allocating resources to a zone experiencing the interference, and a power controller for setting the resources of the zone experiencing the interference to a lower power than the resources of the zone not experiencing the interference to minimize the inter-antenna interference.
