    摘要: An inter-cell interference coordination method coordinates interference between cells neighboring each other and belonging to different base stations by broadcasting interference coordination information between the neighboring cells through a broadcast channel. The terminal relays the interference coordination information between the neighboring cells over the air, so that the interference between the neighboring cells belonging to the different base stations is coordinated.

    摘要: Provided is a method of controlling a transmit power of a control channel transmitted from a pico base station. The pico base station may control the transmit power of the control channel based on a position of a macro terminal adjacent to the pico base station. When the macro terminal is positioned within a coverage of the pico base station, the pico base station enables the macro terminal to receive a control signal without interference from the macro base station by decreasing the transmit power of the control channel.
