    • The present invention relates to a wireless communication system, and more specifically to a method and apparatus for reducing inter-cell interference in a wireless communication system. The method for reducing inter-cell interference in a wireless communication system according to one embodiment of the present invention comprises: allowing the first base station to match the boundary of a downlink subframe to be transmitted to a first terminal from the first base station with the boundary of a downlink subframe received by a second terminal from a second base station; allowing the first base station to acquire timing advance information that indicates the time when the boundary of an uplink subframe from the first terminal to the first base station precedes the boundary of the matched downlink subframe; and allowing the first base station to instruct the first terminal about the transmission time of the uplink subframe from the first terminal to the first base station based on the acquired timing advance information, wherein the boundary of the uplink subframe transmitted to the first base station from the first terminal which has received the instruction can match with the boundary of the uplink subframe transmitted to the second base station from the second terminal.
    • 用于减少无线通信系统中的小区间干扰的方法和设备技术领域本发明涉及无线通信系统,并且更具体地涉及用于减少无线通信系统中的小区间干扰的方法和设备 根据本发明的一个实施例的用于减少无线通信系统中的小区间干扰的方法包括:允许第一基站将待发送到第一基站的下行链路子帧的边界与来自第一基站的 由第二终端从第二基站接收的下行链路子帧的边界; 允许第一基站获取指示从第一终端到第一基站的上行子帧的边界在匹配的下行子帧的边界之前的时间的定时提前信息; 并且允许所述第一基站基于所获取的定时超前信息来指示所述第一终端关于从所述第一终端到所述第一基站的所述上行链路子帧的发送时间,其中从所述第一基站发送到所述第一基站的所述上行链路子帧的边界从 接收到该指示的第一终端可以与第二终端发送给第二基站的上行子帧的边界相匹配。

    • The present invention relates to a wireless communication system, and more particularly, discloses a method and apparatus for reducing inter-cell interference in a wireless communication system. The method for reducing inter-cell interference in a wireless communication system according to one embodiment of the present invention comprises: a step in which a first terminal receives, from a first cell, scheduling information for the transmission of a first signal to a second cell; and a step in which the first terminal transmits the first signal to the second cell on the basis of the scheduling information. The scheduling information is provided by the first cell in the event an uplink or downlink transmission of the first cell is interfered with by an uplink or downlink transmission of the second cell. The first signal indicates a request for reducing the transmitting power of the second cell or of the second terminal served by the second cell.
    • 本发明涉及一种无线通信系统,更具体地,公开了一种用于减少无线通信系统中的小区间干扰的方法和装置。 根据本发明的一个实施例的用于减少无线通信系统中的小区间干扰的方法包括:第一终端从第一小区接收用于向第二小区发送第一信号的调度信息的步骤 ; 以及第一终端基于调度信息将第一信号发送到第二小区的步骤。 如果第一小区的上行链路或下行链路传输受到第二小区的上行链路或下行链路传输的干扰,则调度信息由第一小区提供。 第一信号指示用于降低由第二小区服务的第二小区或第二终端的发射功率的请求。
