Title:
USER DEVICE, BASE STATION DEVICE, AND METHOD
Document Type and Number:
WIPO Patent Application WO/2008/041675
Kind Code:
A1
Abstract:
A user device creates an uplink control channel including at least one of downlink
transmission acknowledgment information and channel state information. When
no resource is allocated for uplink data channel transmission, the uplink control
channel is transmitted by a predetermined dedicated band. The uplink control
channel includes a plurality of unit block sequences obtained by multiplying
all the chips of the Casaque code sequence for the user device by the same factor.
