Title:
RADIO SENDING DEVICE, AND RADIO SENDING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/063937
Kind Code:
A1
Abstract:
Disclosed are a radio sending device and a radio sending method for improving a
throughput while keeping a receiving quality. In this radio sending device, an
MCS switching control unit (102) applies an MCS parameter having a lower quality required
than that of the MCS parameter to be applied to send data arranged at other than
the two end portions of a block, to send data arranged at the two end portions of
the block, and a CP adding unit (105) adds such a CP to the leading end of the block as
is created by copying the trailing end portion of the block composed of the send data,
to which the MCS parameter is applied by the MCS switching control unit (102), with
a length less than the delay time of the maximum delay wave. A send RF unit (106) sends
the send data, in which the CP is added to the leading end of the block, from an antenna
(107).
