Apparatus and method for configuration and optimization of automatic neighbor relation in wireless communication system

A Base Station (BS) apparatus for configuring an Automatic Neighbor Relation (ANR) in a wireless communication system, the apparatus comprising:

• a reception modem for receiving a measurement report message for reporting a neighbor cell's signal quality from one or more User Equipments (UEs);
• and
• a Neighbor Relation Table (NRT) manager for determining a neighbor cell, reported from a UE in an area where a serving cell's signal quality is greater than a first reference value, as an Overlay Neighbor (ON) among neighbor cells reported using the measurement report message, and for determining a neighbor cell, reported from a UE in an area where the serving cell's signal quality is less than a second reference value, as a Horizontal Neighbor (HN) among the neighbor cells reported using the measurement report message, wherein the second reference value is set to a value smaller than the first reference value.

A User Equipment (UE) apparatus for transmitting a measurement report message in a wireless communication system, the apparatus comprising:

• a signal quality measurement unit for measuring a serving cell's signal quality and for measuring a neighbor cell's signal quality if at least one of the serving cell's signal quality is greater than a first reference value and the serving cell's signal quality is less than a second reference value, wherein the second reference value is set to a value less than the first reference value;
• and
• a message generator for generating a measurement report message comprising the measured neighbor cell's signal quality.
