摘要： The present invention makes it possible to obtain the transmission diversity effect by applying a CDD while reducing the inter-code interference when performing a code multiplexing. When an Ack/Nack signal is transmitted from a user terminal to a base station in an upstream control channel by using an Ack/Nack resource, the signal is code-multiplexed by using a code sequence containing an orthogonal sequence and a cyclic-shifted sequence and transmitted from a plurality of user terminals to the base station. Upon using an aggregation size indicating the number of control signals of the downstream control channel, if the aggregation size is greater than one, it is determined that no resource located at the right of the axis of the cyclic-shifted amount of the cyclic-shifted sequence in the same orthogonal code of the orthogonal sequence is used, and the Ack/Nack signal to which CDD is applied from a plurality of antennas is transmitted by using a resource ACK #0 allocated to the own device and an unused resource ACK #1, which have the same orthogonal code, but have different cyclic-shifted amounts.

摘要： There are provided a wireless transmitting apparatus and a wireless transmission method that enable reduction of transmission delay of a system by enhancing receiving performance achieved during transmission of network-coded data. A decoding section 18 subjects a demodulated signal to error correction decoding and outputs the decoded signal to a buffer 17. The buffer 17 holds a data packet for a given period of time and outputs the packet to an encoding section 12. An encoding control section 11 controls an encoding rate for transmission data and outputs control information to the encoding section 12. In accordance with control information from the encoding control section 11, the encoding section 12 subjects a data packet to error correction encoding and outputs the coded data packet to a coding section 13. The coding section 13 subjects data sequences that pair up with each other to XOR processing and outputs a processing result to a modulation section 14. A wireless transmission section 15 subjects a modulated signal to transmission processing, such as digital-to-analogue conversion, up-conversion, and amplification, and transmits the signal subjected to transmission processing from an antenna 16 through wireless communication.

摘要： A radio communication apparatus, a radio communication method, and a radio communication system, which are capable of improving receiving reliability of predetermined bits such as bits having a high degree of importance, and the like, are provided. A code length L is decided based on the modulation system and the coding rate being specified, and the bit length of S2. The relay station decides a coding rate of S1 from the code length L. In the case of 16 QAM, since a half of all bits correspond to the bits used as the object of the quadrant discrimination, the bit length of S1 is set to L/2. Therefore, the coding rate of S1 is 2(LS1)/L, where the bit length of S1 is LS1. In the present example, S1 is coded and gives S1+P1, and S2 is coded and gives S2+P4. P1 denotes the parity bit of S1, and P4 denotes the parity bit of S2. The relay station changes the bit arrangement such that all bits of the code word (S1+P1) of S1 come to the position of the quadrant discrimination in the constellation of 16 QAM respectively.

摘要： The invention provides a base station that does not cause the number of blind decodings to be increased and further can prevent the flexibility of resource allocation from degrading. A search space setting unit (103) sets search spaces each of which is constituted by one or more control channel elements (CCEs) and each of which is to be decoded in the terminals and each of which is defined by a plurality of to-be-decoded candidates. An allocating unit (108) places, in one of the plurality of to-be-decoded candidates included in the search space, a control channel. The number of connections of CCEs constituting the to-be-decoded candidate is associated with the number of to-be-decoded candidates. The search space setting unit (103) causes, in accordance with the control channel to be transmitted, the association of the number of connections of CCEs constituting the to-be-decoded candidate with the number of to-be-decoded candidates to differ.
