摘要： Provided is a radio communication apparatus capable of always obtaining the optimum error rate characteristic when an LDPC code is used for an error-correcting code. In the apparatus, a temporary bit insertion section (101) inserts a temporary bit into a position equivalent to that of the systematic bit corresponding to a variable node having the largest number of connections with a check node in the Tanner graph corresponding to a check matrix in a transmission bit string and outputs the generated bit string to an LDPC coding section (102), The LDPC coding section (102) performs LDPC coding on the bit string inputted from the temporary bit insertion section (101) by using the check matrix and obtains an LDPC code word composed of the systematic bit and a parity bit. The LDPC code word is outputted to a temporary bit removal section (103).

摘要： Disclosed is a wireless communication apparatus and wireless communication method wherein flexible frequency scheduling is performed without increasing the scale of the DFT (Discrete Fourier Transform) circuitry. For example, when resource allocation information is reported indicating whether or not a resource has been allocated to each of a plurality of RBGs (RB groups) into which the system bandwidth is divided, as in Type 0 allocation, if the number of reported RBs reported by the resource allocation information cannot be expressed as “2̂n×3̂m×5̂l”, an allocated RB number setting section (208) sets the number of allocated resource blocks used in the actual transmission band, corresponding to the reported RB number, to the number of resource blocks that can be represented by any of “2̂n×3̂m×5̂l”, and an allocated RB selection section (209); selects the allocated RB employed in the actual transmission band from the resource allocation information and allocated RB number

摘要： Disclosed are a wireless transmission apparatus and transmission power control method which improve the error rate characteristics of data signals even when the number of streams of data signals increases, without increasing the amount of signaling. The relationship between the number of streams of data signals in each antenna (201-1, 201-2) and the data signal and pilot-signal transmission power ratio at each antenna (201-1,201-2) is stored. Specifically, a relationship where the data signal and pilot signal transmission power ratio at each antenna increases as the number of streams of data signals at each antenna increases is stored. A transmission power control unit (205) determines the data signal and pilot signal transmission power ratio on the basis of the information of the number of streams of data signals at each antenna (201-1, 201-2) that were output from a decoding unit (204), controls the transmission power of the pilot signals on the basis of the determined transmission power ratio, and outputs to a multiplexing unit (210).

The base station includes: a modulation unit (102) for modulating SCH data after being encoded; a sub carrier setting unit (105) for setting one of the sub carriers to a sub carrier (SCH sub carrier) constituting the OFDM symbol for SCH data transmission; and an IFFT unit (106) for mapping the SCH data to the sub carrier set by the sub carrier setting unit (105) among the sub carriers and performing IFFT to generate an OFDM symbol. The sub carrier setting unit (105) sets one of the sub carriers which has a frequency of a common multiple between the sub carrier interval and the cell search interval as an SCH sub carrier.

In a case of adding the short GI, the GI adding part (103) copies the symbols of a portion of the data part including the rear thereof, and adds the copied symbols to the head of that data part, thereby providing a GI. In a case of adding the long GI, the GI adding part (103) copies the symbols of a portion of a second data part, which immediately follows the first data part, including the rear of the second data part. Then, the GI adding part (103) adds the copied symbols to the head of the first data part, thereby providing the second GI. Moreover, the GI adding part (103) copies the symbols of a portion of the first data part including the rear thereof, and then adds the copied symbols to the head of the second GI added to the first data part, thereby providing the first GI.
