Title:
MOBILE STATION DEVICE, BASE STATION DEVICE, WIRELESS COMMUNICATION METHOD, AND COLLECTION CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2013/137164
Kind Code:
A1
Abstract:
This mobile station device and base station device correctly communicate using E-PHICH. The mobile station device receives information designating a subframe reserved for transmitting HARQ feedback using an expanded physical HARQ indicator channel, and if the time of receiving HARQ feedback with respect to transport block transmission using the expanded physical HARQ indicator channel involves a subframe other than the subframe designated by the information, when receiving the HARQ feedback with respect to the transport block transmission, an ACK (acknowledgement) is set to the state variable managed by the HARQ process to which the transport block corresponds.
