    Abstract: Disclosed is a frequency hopping method in an OFDM system, comprising: (a) detecting a mutual interference degree between different cells, and determining whether to use different frequency hopping patterns between the cells for interference averaging according to the mutual interference degree; (b) determining a number P of the different frequency hopping patterns needed between all the cells in the system; (c) generating the frequency hopping patterns of more than the number P, and allocating the generated frequency hopping patterns to each cell, the frequency hopping patterns having the same frequency collision times between two channels in the different frequency hopping patterns; and (d) frequency-hopping the channels in each cell according to the allocated frequency hopping pattern.

    Abstract: Disclosed is a method for controlling interference in a heterogeneous network environment. The method for controlling the inter-cell interference of a base station according to one aspect of the present invention comprises the following steps: transmitting, to a terminal, information relating to subframes in which a portion of a resource is to be punctured; transmitting, to the terminal, a relevant subframe in which a portion of a resource is punctured on the basis of the information relating to said subframes. A method for controlling the inter-cell interference of a base station according to another aspect of the present invention comprises the following steps: setting a resource for transmitting system information; and transmitting system information using only said resource for transmitting system information, or preferentially using said resource for transmitting system information when transmitting system information using a subframe designated as an almost blank subframe (ABS). Accordingly, inter-cell interference problems may be alleviated even in the event pieces of important system information, such as CRS, should be transmitted using an ABS.

    Abstract translation: 公开了一种用于控制异构网络环境中的干扰的方法。 根据本发明的一个方面，用于控制基站的小区间干扰的方法包括以下步骤：向终端发送与其中要对一部分资源进行打孔的子帧有关的信息; 基于与所述子帧相关的信息向终端发送其中部分资源被打孔的相关子帧。 根据本发明的另一方面，一种用于控制基站的小区间干扰的方法包括以下步骤：设置用于发送系统信息的资源; 以及仅使用用于发送系统信息的所述资源来发送系统信息，或者当使用被指定为几乎空白子帧（ABS）的子帧来发送系统信息时优先使用所述用于发送系统信息的资源。 因此，即使在使用ABS传输重要系统信息（诸如CRS）的情况下，也可以缓解小区间干扰问题。

    Abstract: A data transmission and reception method in a cooperative communication system is provided. The data transmission method of a base station in a cooperative communication system includes: generating a first code word for cooperative transmission and a second code word for direct transmission to a mobile station (105); and transmitting a signal including one or more of the first and second code words to a relay equipment (103) for cooperative transmission and the mobile station (105). The first and second words are independent from each other.

    Abstract: Disclosed is a transmission system for transmitting reference signals with information on the state of a channel for extracting channel state information to a relay and a macro terminal. A base station transmits to the relay or the macro terminal the information on a sub-frame, which includes the channel state information reference signal. The relay and the macro terminal receive the channel state information reference signal using the information on the sub-frame. The relay and the macro terminal extract the channel state information using the channel state information reference signal, and transmit the extracted channel state information to the base station.
