摘要： Provided are a transmission device and transmission method that are capable of allowing leeway in data reception processing on the receiving side regardless of the position in time of a resource region to which control information, which is contained in resource allocation information for transmission data, is mapped. A setting unit (101) sets a mapping region, which maps a DCI in accordance with the downlink data size that the DCI indicates, from among a PDCCH region, an R-PDCCH region in slot 0, and an R-PDCCH region in slot 1 that are provided in order in the time direction within a subframe. In a setting rule table used in setting the mapping region, PDCCH region, R-PDCCH region in slot 0, and R-PDCCSH region in slot 1 are associated with maximum size value of a downlink data size that the DCI indicates and that can be set in each resource region.

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.
