Title:
BASE STATION, USER DEVICE AND METHOD USED IN MOBILE COMMUNICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2007/148583
Kind Code:
A1
Abstract:
A base station used in a mobile communication system with a single carrier method
adopted for an uplink is comprised of a scheduler for allocating not less than
one resource block of the uplink to each of user devices, and a means for notifying
the user device of scheduling information indicative of planning contents of
resource allocation in accordance with an up channel state of each of the user
devices. An up control channel of a user device is mapped so that the up control
channel draws a predetermined hopping pattern in a transmission frame including
a plurality of resource blocks in accordance with scheduling information. The
up control channel is mapped in the same hopping pattern even with or without a
user data channel.
