COGNITIVE RADIO COMMUNICATION SYSTEM BASED ON A COOPERATION SIGNAL OF THE SECONDARY SYSTEM, CAPABLE OF ENABLING THE PRIMARY BASE STATION TO ALLOCATE RADIO RESOURCES TO THE SECONDARY SYSTEM ACCORDING TO A CONTRIBUTION LEVEL OF A COOPERATION SIGNAL

摘要

PURPOSE: A cognitive radio communication system based on a cooperation signal of the secondary system is provided to allocate radio resources usable according to contribution of a cooperation signal of the secondary system, thereby maximizing performance of the secondary system and the primary system.;CONSTITUTION: A receiver(610) receives an uplink signal from the primary terminal. The receiver receives a cooperation signal related to the uplink signal from the secondary system. An evaluator(630) evaluates contribution of the cooperation signal about the detection of the uplink signal. A radio resource manager(640) controls available radio resources for the secondary system.;COPYRIGHT KIPO 2010
