Title:
BASE STATION APPARATUS AND TERMINAL APPARATUS
Document Type and Number:
WIPO Patent Application WO/2010/122808
Kind Code:
A1
Abstract:
A base station apparatus and terminal apparatus with a configuration which achieves highly flexible retransmission control while preventing increases in the uplink control channel overhead. In the base station (100), a control unit (101) configures a bundling unit band group including first and second downlink unit bands, and a mapping unit (108) maps initial transmission data to the first and second downlink unit bands as well as maps retransmission data to a third downlink unit band excluding the downlink unit bands of the bundling unit band group. Further, in the terminal (200), a bundling control unit (212) transmits a response signal for the initial transmission data with the constituent resources of an uplink control channel provided in an uplink unit band and linked to the downlink control channels of the downlink unit bands used to transmit the initial transmission data, and transmits a response signal for the retransmission data using resources different from that of the response signal for the initial transmission data.
