Abstract: When it is worried that an ISI might occur since the downlink synchronization has an error, a terminal receives a ranging response from a base station, modifies the downlink synchronization, and thus the uplink synchronization can be obtained. In a cooperative communication network, an up-down link synchronization acquiring/modifying method capable of effectively preventing the disagreement in signal transmission synchronization of base stations, over-attenuation of transmitted signals, or interference between symbols due to a delay because of the difference between reflection route.

Abstract: PURPOSE: A base station, a method for managing a cell, a method for detection a signal, a terminal and a method for transmitting a signal thereof are provided to improve the performance of a terminal positioned at a cell boundary of a mobile communication system and prevent the terminal from operating as interference to a neighboring cell. CONSTITUTION: A base station(100) allocates a resource to a terminal and transmits and receives data to and from the terminal. A receiver(111) receives information an environment of the terminal from the terminal positioned at the boundary between cells. A serving base station and a neighbor base station transmit and receive signals to and from each other through a backbone network. A resource allocator(113) allocates the resource to the terminal on the basis of the allocation information received from the neighbor base station. A signal detector(114) receives the signals from the terminal positioned at the cell boundary and another terminal positioned in the cell and then detects a transmission signal of the terminal by removing the reception signal from the terminal. The signal detector uses joint detection.

Abstract: PURPOSE: If a symbol which beam is formed and a symbol which beam is not formed are mixed in one frame, a device for gain control and a method for receiving signal are provided to revise a wireless signal by considering a average power of the symbol which beam is formed, thereby performing an accurate gain control. CONSTITUTION: A map interpreter grasps a symbol section which beam is formed among wireless signals. According to output of a map interpreter, a power calculator(620) calculates average power of the symbol section which beam is formed. A gain calculator(630) outputs a gain control signal from output of the power calculator. A switch(650) outputs a gain from the gain control signal. Based on a gain, the wireless signal is revised.
