摘要： In a communication system including a plurality of base stations and a plurality of terminals belonging to each of the base stations, the base station receives information on subcarriers allocated to a terminal that belongs to an adjacent base station from the adjacent base station. Thereafter, the base station generates power control information on the basis of the subcarrier information and transmits the power control information to the terminal, and the terminal controls uplink power on the basis of the received power control information. At this time, the power control information, as information based on estimating hitting between subcarriers used by the terminal that belongs to the base station and subcarriers used by the adjacent base station, may be a ratio found by dividing the total number of subcarriers used by each terminal that belongs to the adjacent base station by the entire number of subcarriers that can be used by the base station.

摘要： The present invention relates to an apparatus and a method for selection of a precoding matrix. In the present invention, a precoding matrix to enable an effective signal-to-noise ratio (ESNR) to have a maximum value with respect to a signal vector that requires retransmission is selected in a codebook and fed back to a transmitter. Accordingly, since the effective signal-to-noise ratio has the maximum value after the signal vector is retransmitted, it is possible to minimize a reception error probability of retransmission.
摘要翻译：本发明涉及用于选择预编码矩阵的装置和方法。在本发明中，在码本中选择能够使有效信噪比（ESNR）相对于需要重发的信号矢量具有最大值的预编码矩阵并反馈给发送机。因此，由于有效的信噪比在重发信号矢量之后具有最大值，所以可以最小化重传的接收错误概率。

摘要： In an orthogonal frequency division multiple access (OFDMA) communication system, a transmission apparatus connects multiple tiles, which have a 4×3 structure, along a time or frequency axis in an uplink 4-layer partial usage of subchannels (PUSC) mode, and designs pilots corresponding to one layer at one of multiple symbol positions adjacent to a first corner of the tiles and one of multiple symbol positions adjacent to a second corner of the tiles that face the first corner in a diagonal direction. In this case, null symbols are designed at the rest of the symbol positions adjacent to the first corner or the second corner where the pilots are not designed. Accordingly, a receiving apparatus can obtain n channel values from n tiles. Further, n estimated channel values are applied to a linear interpolation method, so that it is possible to estimate the entire channel value of n tiles.
