Title:
WIRELESS COMMUNICATION APPARATUS AND WIRELESS COMMUNICATION METHOD
Document Type and Number:
WIPO Patent Application WO/2011/004531
Kind Code:
A1
Abstract:
The present invention is directed to prevention of erroneous identification of ACK/NACK from occurring even in a case where the overlook of a control channel has occurred. In a data allocation control channel A-MAP for downlink control signals, an HFA is transmitted which designates an uplink HFBCH resource to be used for causing an ACK/NACK to be fed back. Consecutively even-numbered and odd-numbered resources are notified as the HFA, thereby designating 2-bit FB to send back the ACK/NACK related to two pieces of data. A particular area for 2-bit FB is provided in this HFA, and when 2-bit FB is to be used, a control signal using the HFA having the particular area for 2-bit FB is generated and transmitted, thereby allowing the reception overlook of an A-MAP to be determined. On the receiving side, when the HFA having the particular area is received and the reception overlook of the A-MAP is determined, a NACK is sent back for the data that cannot be received.
