Abstract: PURPOSE: A method and an apparatus for triggering a multi-cell MIMO schemes in a multiple antenna system are provided to reduce the scheduling complexity and decrease the number of feedback information by providing a mechanism for determining a multi-cell MIMO transmission scheme. CONSTITUTION: A threshold determiner(106) of a BS(Base Station)(100) determines a threshold NIP_th_1 for triggering a first multi-cell MIMO scheme and a threshold NIP_th_2 for triggering a second multi-cell MIMO scheme based on network measurements. The BS determines the thresholds such that the greatest NIP values of the NIP values fed back from the MS may constitute 5 percentage of the total NIP values fed back from the MS. Typically, NIP_th_1 is smaller than NIP_th_2. The BS does not request the NIP report from multiple MSs, but may periodically receive the NIP report from the MSs. A preprocessor(107) of the BS broadcasts the NIP_th_1 and the NIP_th_2 using downlink broadcast messages based on an OFDM(Orthogonal Frequency Division Multiplexing) communication scheme. Upon receiving the request for the first multi-cell MIMO scheme or the second multi-cell MIMO scheme from the corresponding MS, a controller(101) of the BS requests feedback information for the proper multi-cell MIMO scheme.
Abstract translation: 目的：提供一种用于在多天线系统中触发多小区MIMO方案的方法和装置，以通过提供用于确定多小区MIMO传输方案的机制来减少调度复杂度并减少反馈信息的数量。 构成：BS（基站）（100）的阈值确定器（106）确定用于触发第一多小区MIMO方案的阈值NIP_th_1和用于基于网络测量触发第二多小区MIMO方案的阈值NIP_th_2。 BS确定阈值，使得从MS反馈的NIP值的最大NIP值可以构成从MS反馈的总NIP值的5％。 通常，NIP_th_1小于NIP_th_2。 BS不从多个MS请求NIP报告，但可以定期从MS接收NIP报告。 基于OFDM（正交频分复用）通信方案，BS的预处理器（107）使用下行链路广播消息来广播NIP_th_1和NIP_th_2。 在从对应的MS接收到针对第一多小区MIMO方案或第二多小区MIMO方案的请求时，BS的控制器（101）请求适当的多小区MIMO方案的反馈信息。

Abstract: PURPOSE: A method and device for transmitting control information for interference mitigation from a multiple antenna system are provided to feedback a PMI(Precoding Matrix Index) subset based on correlation between the best or worst PMI and other PMI, thereby reducing an overhead. CONSTITUTION: A terminal(110) uses correlation between a first or a second PMI and other PMI within the code book to feedback related PMI subset information. A serving base station(100) forwards the related PMI subset information to an interfering base station(120). The interfering base station determines a PMI subset from the related PMI subset information. The first PMI largely raises interference to neighboring base station. The second PMI largely alleviates interference of the neighboring base station.
