摘要： In a multicell communication system, a terminal that belongs to a second cell using the same subcarrier as a terminal that belongs to a first cell changes a pilot in an allocated basic resource block. Then, a base station that manages the first cell can estimate a channel of an interference signal transmitted from a second cell from a reception signal even though the reception signal includes an interference signal from the terminal that belongs to the second cell at the time of receiving a signal transmitted from the terminal that belongs to the first cell. Further, the base station that manages the first cell may reduce an interference signal from a reception signal by using a channel estimation value.

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.

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： A mobile station and a base station communicate with each other using a frame including one or more downlink subframes and one or more uplink subframes. The base station begins the transmission of a data burst in a subframe corresponding to a downlink subframe index. The mobile station transmits feedback for the data burst to the base station in a subframe corresponding to an uplink subframe index. If the frame uses a time division duplex scheme, the uplink subframe index is determined by at least using the downlink subframe index and the parameter value.
