摘要： In an orthogonal frequency division multiple access (OFDMA) communication system, a transmission apparatus connects a plurality of tiles, which have a 4x3 structure, along a time axis or a frequency axis in an uplink 4-layer PUSC mode, and designs pilots corresponding to one layer at one of a plurality of symbol positions adjacent to a first corner of the plurality of tiles and one of a plurality of symbol positions adjacent to a second corner of the plurality of 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 transmission method of a base station is provided. The base station generates a first discovery signal block including a first PSS (primary synchronization signal) and a first SSS (secondary synchronization signal). The base station generates a second discovery signal block including a second PSS and a second SSS. Also, the base station transmits the first discovery signal block and the second discovery signal block.

摘要： Disclosed is a method for configuring a bandwidth for supporting a broadband carrier in a communication system. An operation method of a base station comprises the steps of: configuring a first bandwidth part and a second bandwidth part for a terminal; configuring a reserved resource for the first bandwidth part in a resource area in which the first bandwidth part and the second bandwidth part overlap; and performing an operation of transmitting or receiving a second data channel, which is scheduled to the second bandwidth part, together with the terminal by using the reserved resource. Therefore, the performance of the communication system can be improved.

摘要： Disclosed is a method and apparatus for transmitting or receiving a control channel in a communication system. A method for transmitting control information by a base station comprises the steps of: configuring a control resource set including a plurality of REGs; interleaving, on a frequency axis, the plurality of REGs included in the control resource set; configuring an REG pool including at least two interleaved REGs; configuring at least one CCE in the REG pool; and transmitting control information through a search space configured by the at least one CCE. Therefore, the present invention can improve performance of a communication system.
