Abstract: An interference cancellation method of an uplink reception signal in a time division duplex system and a device thereof are provided to cancel interference of a downlink transmission signal of a neighbor base station for an uplink signal in a CTS(Cross-Time Slot) section of a dynamic time division duplex system, thereby increasing accuracy in detection of a signal sent from a terminal. When an uplink signal is received from a terminal, it is decided whether an uplink section where the signal is received is overlapped with downlink sections of neighbor base stations(501~505). If so, channels of the neighbor base stations are estimated(507). Downlink transmission signal information of the neighbor base stations is detected from the overlapped section(509,513). Interference of the neighbor base stations for the uplink signal is cancelled by using the estimated channels and the detected information(515).

Abstract: An apparatus and a method for transmitting/receiving signals in a communication system are provided to prevent a waste of UL(Uplink)/DL(Downlink) resources by using a QDCCH(Quasi Dedicated Control CHannel) as a UL resource for providing a specific service, such as an rtPS(realtime Polling Service), etc., so that UL/DL resources can be allocated according to characteristics of burst data. A base station in an IEEE 802.16e communication system comprises a controller(715) and a sub-channel allocator(713). The controller(715) executes a control operation so that a QDCCH can be allocated to the first mobile station. Also, the controller(715) executes a control operation so that the QDCCH allocated to the first mobile station can be allocated to the second mobile station only during a preset time. The sub-channel allocator(713) allocates the QDCCH to the first mobile station or the second mobile station according to control of the controller(715).

Abstract: 본 발명은 패킷 기반 실시간 서비스를 지원하는 무선 통신 시스템에서 현재 연결된 채널 외에 다른 채널을 통해 제어 패킷을 전송하기 위한 상향링크 자원을 할당하는 방법에 관한 것이다. 이를 위해 본 발명에서는 기존에 동일한 연결에 대해서만 사용하던 피기백 요청 (piggyback request)을 다른 연결에 대해서도 사용할 수 있도록 그랜트 관리 서브헤더의 새로운 포맷을 제안한다. 그리고 새로이 제안된 그랜트 관리 서브헤더를 이용하여 다른 연결을 위한 자원 할당을 요청할 수 있도록 한다. 이와 같이 그랜트 관리 서브헤더를 이용하여 새로운 연결에 대한 자원 할당을 요청하게 되면, 해당 자원을 할당 받기까지의 소요 시간을 줄일 수 있을 뿐만 아니라 기존의 연결에 대해 할당된 자원의 손실 또한 최소화할 수 있다.

Abstract: A system and method for handover in a mobile communication system are provided to prevent data reception delay or errors due to scanning by making a mobile station execute scanning only in one frequency band or one frequency operation mode in a communication system where a base station operates at least two frequency bands or uses at least two frequency operation modes. A serving base station periodically transmits a neighbor base station advertisement(MOB_NBR-ADV) message to a mobile station(302). Receiving the MOB_NBR-ADV message, the mobile station decides to perform scanning for handover if signal strength of the serving base station falls below preset critical signal strength(304). The mobile station transmits a MOB_SCN-REQ(Mobile_Scanning Interval Allocation-Request) message to the serving base station(306). Receiving the MOB_SCN-REQ, the serving base station transmits a RESOURCE-RESERVE-REQ message to neighbor base stations(308,310). Each of the neighbor base stations, receiving the RESOURCE-RESERVE-REQ message, sends a RESOURCE-RESERVE-RSP message to the serving base station in case a radio resource corresponding to a specific band(mode) which can be used for the handoff of the mobile station exists(S314,316).

Abstract: A handoff method in a mobile communication system is provided to minimize the degradation of QoS(Quality of Service) in handoff by estimating uplink/downlink channel information and using them for resource allocation of a mobile terminal in handoff. When a mobile terminal for which a session is maintained for uplink/downlink data transmission/reception(S302) moves to a cell boundary area, handoff is performed(S304). Channels of uplink/downlink between adjacent base stations and the mobile terminal are estimated(S306) and a base station that has the best channel state and resources which can receive the mobile terminal is determined as a target base station(S308). Resources that are most suitable for QoS of the mobile terminal are reserved(S310). The reserved resources are allocated to the mobile terminal and at the same time handoff is performed(S312).
