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 are a radio transmission device and a radio transmission method capable of containing a plenty of mobile stations for receiving low-rate data and avoiding lowering a system throughput. A group ID assigning unit (108) groups UE receiving low-rate data and assigns a frequency by using the group ID. An SCCH processing unit (109) generates an SCCH containing the group ID. A low-rate control information processing unit (113) generates low-rate control information indicating a timing slot to which a low-rate UE has been assigned. A multiplexing unit (117) multiplies low-rate control information on RB to which low-rate data is assigned when multiplexing a pilot channel, SCCH, and data.

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).
