Title:
TRANSMITTER AND RECEIVER
Document Type and Number:
WIPO Patent Application WO/2007/129538
Kind Code:
A1
Abstract:
A transmitter used in a mobile communication system employing a single-carrier system
on the uplink comprises a multiplexing means for multiplexing a pilot channel,
a control channel, and a data channel and a transmitting means for transmitting a
transmission symbol including at least the pilot channel and the control channel on
the uplink. A first pilot channel for measuring the uplink channel state with a
receiver is transmitted in a frequency band over a plurality of resource blocks. A
second pilot channel for compensating the channel transmitted on the uplink is
transmitted by a resource block allocated to the station. The control channels of
the local station and the other station are made to intersect at right angles each
other in an FDM system.
