摘要： Provided is a wireless communication device which can improve the notification accuracy of the channel state information (CSI) without straining the feedback circuit. In this device, a channel estimator (105) uses a pilot signal input from a wireless receiver (102) to estimate the channel and obtain a plurality of path gains in each of a plurality of delay periods. Then, the channel estimator (105) outputs the plurality of path gains to a quantizer (107). The quantizer (107) quantizes the plurality of path gains in the number of notification bits corresponding to each of the plurality of delay periods based on the correspondence of the delay period and the number of notification bits input from a setting unit (106).

摘要： A wireless communication apparatus wherein the power consumption can be reduced. In this apparatus, a code block dividing part (101) divides a transport block, in which filler bits have been inserted, into a plurality of code blocks. A mapping control part (107) controls, based on both scheduling information, which is received from a scheduler (not shown) and indicative of physical channel resources to be used for code block transmission, and the number of filler bits which is received from the code block dividing part (101), the plurality of code blocks so that they will be mapped to the respective physical channel resources in such an order that a respective code block having a less number of filler bits will be mapped to a respective more forward physical channel resource. A mapping part (108) then maps, based on mapping information received from the mapping control part (107), data symbols, which are received from the modulating parts (106) of the respective ones of code block processing parts (102-1 to 102-C), to the physical channel resources.

摘要： Provided is a wireless communication terminal which, when SRSs are simultaneously transmitted between CCs and between antenna ports, avoids increasing the effect of bit rounding errors of D/A converters when the number of antenna ports set for SRS transmission differs between CCs. This device comprises a transmission power calculation unit (107) which calculates the transmission power of a plurality of UL channels of a plurality of CCs and a plurality of antenna ports. A power scaling detection unit (108) detects whether or not the total transmission power of the UL channels exceeds the maximum transmission power specific to a UE. When power scaling is generated, a power scaling control unit (109) uses antenna port setting information set for SRS transmission between CCs to perform power scaling in such a way that all scaling weights are uniform between CCs, or between CCs and between antenna ports.

摘要： There is provided a wireless communication device capable of improving a decoding performance by using an optimal selection criterion for a start address and a read direction in a circular buffer. An interlacer (13) writes an interleaved and interlaced bit sequence into a circular buffer (14). An RV decision unit (109) decides the read start address and read direction of the circular buffer (14) based on the number of non-transmitted systematic bits, the number of non-transmitted important parity bits, and/or the number of non-transmitted unimportant parity bits. A read control unit (110) controls the read start address and read end address of the circular buffer (14). A read unit (15) is controlled by the read control unit (110) to continuously read encoded bits from the circular buffer (14).
