Abstract: An apparatus and a method for full duplex relay convertible between relay mode and a repeater mode are provided to enable a receiving and transmitting data at the same time by applying interference cancellation system. While a transmit modem(409) operates to the relay mode, when the unused resources is generated, it is generated the control signal for changing into the relay mode. The relay mode is the mode for encoding data received from transmitter into again after the demodulation and decipher and modulating and transmitting with receiver. The relay mode is the mode for just amplifying the signal received from transmitter and transmitting with receiver. According to the reception switch(423) is the control signal for the change over to the relay mode, signal from the RF/IF reception end(401) is switched with the transmission switch(425). According to the transmission switch is the control signal for the change over to the relay mode, the signal switched from the reception switch is switched with the RF/IF transmitting end(413).

Abstract: An apparatus and a method for controlling traffic among switching entities in all IP network are provided to prevent the interrupt of a service caused by compulsorily reducing traffic by linking some BS(Base Station)s generating overload with different SE(Switching Entity) when generating overload traffic. Traffic information is received from corresponding BSs(400). Traffic information is collected from the BSs and the total amount of traffic is calculated(402). If the total traffic is greater than critical value, a base station transmitting the greatest traffic is selected and a priority is assigned(410). It determines whether the base station assigned the priority is capable of linking with arbitrary SE. The arbitrary SE determines whether to process the traffic of the BS acquiring the priority.

Abstract: Apparatus and a method for converting a repeater station mode are provided to reduce resources linked with a base station and a repeater station in the wireless telecommunications system of the repeater system by converting the repeater station mode according to the amount of resource usage. A base station(110) performs communication through a plurality of terminals and the radio channel within a cell. A base station does not perform communication directly linked with some terminals within a repeater station cell and performs communication through the repeater station. After the repeater station(120) converts into the base station mode, the repeater station converts into the relay mode if the used resource amount is less than the standard value. The standard value is changed according to the set up of system.

Abstract: An HD(Hybrid Duplex) complexity reducing device through selective antenna allocation in a multi-antenna system and a method are provided to allocate transmission reconfigurable RF(Radio Frequency) chains and reception reconfigurable RF chains by dividing the RF chains to TDD(Time Division Duplex) bands and FDD(Frequency Division Duplex) bands, thereby realizing an HD mode without increasing the number of the RF chains. Antenna transmission RF chains operate in TDD band mode. Antenna reception RF chains operate in TDD band mode or in FDD band mode according to generated frequencies. An antenna selector(317) estimates channels for the TDD band and the FDD band by using a pilot signal received from a terminal, and determines reception antenna sets to be allocated to TDD bands. A frequency generator and controller(316) generates TDD band frequencies with the antenna transmission RF chains and the reception RF chains of the determined reception antenna sets, and generates FDD band frequencies with reception RF chains of other reception antenna sets.

Abstract: An apparatus and a method for resource allocation in a multi-hop relay wireless communication system are provided to allocate different frequency resources to a link which is strongly influenced by adjacent cells and a link which strongly influences the adjacent cells by using hybrid duplexing, thereby reducing influence by interference between the adjacent cells and adjusting the amount of the resources allocated to each link free. A method for constructing a frame(400) in a multi-hop relay wireless communication system comprises the following steps of: constructing the subframe of a link influenced from adjacent cells during the first frequency band(460) of the frame; and constructing the subframe of a link having influence on the adjacent cells during the second frequency band(470) of the frame. The subframe of the link, not influenced by the adjacent cells, is allocated to the first frequency band or the second frequency band of the frame.
