RADIO RESOURCE ALLOCATION APPARATUS AND METHOD USING INTERFERENCE INDICATOR IN FEMTO CELL NETWORK

摘要

A radio resource allocation apparatus and method using an interference indicator in a femto-cell network are disclosed. The radio resource allocation apparatus using an interference indicator in a femto-cell network includes: an interference indicator obtaining unit obtaining any one or more of interference indicators including load information of a base station in the femto-cell network, a change amount of reference signal received power (RSRP) to reference signal received quality (RSRQ), and a channel quality indicator (CQI); a priority determining unit providing different weights to each of the interference indicators and determining an allocation priority of radio resources using the interference indicators to which the weights are provided; and a radio resource allocating unit allocating the radio resources to the base station in any one of a dedicated carrier mode, a partially shared carrier mode, and a shared carrier mode using the allocation priority.
