    • A calibration apparatus and a calibration method for multicell Multiple Input Multiple Output (MIMO) transmission in a multiple antenna system are provided. More particularly, an operating method of a Mobile Station (MS) for performing calibration for multicell MIMO transmission in a multiple antenna system includes negotiating a multi-Base Station (BS) joint processing with a BS, receiving a control message including information instructing multi-BS calibration for sounding based on the multi-BS joint processing, from the BS; when receiving the control message involving the multi-BS joint processing, generating a second sounding sequence by mapping estimated phases of downlink channels per subcarrier of BSs to a first sounding sequence allocated from the BS, and transmitting the second sounding sequence, including the phases of the downlink channels per subcarrier, over a sounding symbol interval with respect to each of the BSs involving the multi-BS joint processing. Hence, feedback overhead in the calibration of the multicell MIMO transmission can be reduced.
    • 提供了用于多天线系统中的多单元多输入多输出(MIMO)传输的校准设备和校准方法。 更具体地,用于在多天线系统中执行用于多小区MIMO传输的校准的移动站(MS)的操作方法包括:与BS协商多基站(BS)联合处理,接收包括指示多基站 基于多基站联合处理的基于BS的校准的BS校准; 当接收涉及多BS联合处理的控制消息时,通过将BS的每个子载波的下行链路信道的估计相位映射到从BS分配的第一探测序列来产生第二探测序列,并且发送第二探测序列,该第二探测序列包括 每个子载波的下行信道,在涉及多BS联合处理的每个BS的探测符号间隔内。 因此,可以减少多小区MIMO传输的校准中的反馈开销。

    • An method of a mobile station for transmitting a ranging signal in a wireless communication system which supports Fractional Frequency Reuse (FFR) and an apparatus for performing the method are provided. The method includes receiving information of ranging resource allocation, from a base station, based on the information of the ranging resource allocation, determining a cell identifier and a Frequency Partition (FP) location for uplink control channels, determining a subband index for the ranging resource allocation based on the cell identifier and a number of subbands allocated to the FP location for the uplink control channels, and transmitting a ranging signal based on the subband index for the ranging resource allocation. Thus, interference to a neighboring cell may be reduced in the ranging channel transmission.
    • 提供了一种用于在支持分数频率重用(FFR)的无线通信系统中发送测距信号的移动台的方法以及用于执行该方法的装置。 该方法包括基于测距资源分配的信息从基站接收测距资源分配的信息,确定用于上行链路控制信道的小区标识符和频率分区(FP)位置,确定测距资源的子带索引 基于所述小区标识符和为所述上行链路控制信道分配给所述FP位置的多个子带分配分配信息,以及基于所述测量资源分配的所述子带索引来发送测距信号。 因此,在测距信道传输中可能减少对相邻小区的干扰。
