Title:
TRANSMISSION DEVICE AND TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2012/042889
Kind Code:
A1
Abstract:
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. In a base station (100), 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, the 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.
