摘要： Provided are a radio transmission apparatus and a radio transmission method whereby the increase of number of signaling bits can be suppressed and further the flexibility of frequency scheduling can be improved. A notified RBG calculating unit (203) that adds a predetermined offset value of “1” or “−1” to one of the start RBG number and the end RBG number of allocated RBG number information (b′i) output by a scheduling unit (201), thereby calculating notified RBG number information (bi). An RBG total number setting unit (204) calculates the total number of RBGs, which is to be notified, by adding “1” to the total number of allocated RBGs. A notified information generating unit (205) applies the notified RBG number information (bi) and the notified total number of RBGs (Nrb′) to a predetermined formula, thereby generating and transmitting, to terminals, notified information (r).

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).
