Abstract: PURPOSE: A device and a method for suppressing interference between adjacent sectors in a communication system based uplink SDMA are provided to perform cooperation scheduling and uplink power control in a communication system based on uplink SDMA, thereby suppressing interference between adjacent sectors. CONSTITUTION: A path loss determining unit receives a downlink signal from adjacent sectors and determines average receiving power per each sector(202). The path loss determining unit calculates average downlink path loss per each sector using the average receiving power per each sector(204). A transmission power determining unit determines maximum transmission power from the downlink path loss per each sector based on minimum path loss. A controller transmits the determined maximum transmission power to a base station.

Abstract: PURPOSE: A power control device for minimizing uplink interference of an indoor base station in a mobile communication system and a method thereof are provided to minimize the interference about outdoor user and transmit uplink data of high quality. CONSTITUTION: A power control device for minimizing uplink interference of an indoor base station in a mobile communication system and a method thereof are as follows. An interference and noise level information are acquired from the outdoor base station(302). The maximum permissible interference amount of the inside of a user terminal is adaptively controlled according to an interference and noise level. The maximum transmission electric power of the inside of the user terminal is calculated by the maximum permissible interference amount of the inside(316).
