Title:
WIRELESS TRANSMITTER AND WIRELESS TRANSMITTING METHOD
Document Type and Number:
WIPO Patent Application WO/2007/083665
Kind Code:
A1
Abstract:
A wireless transmitter and a wireless transmitting method in a communication system
are provided with features in which a contention based channel and a scheduled channel
are time-division-multiplexed, influence of interference between the channels
is reduced while receiving quality is improved even if a delay in the contention
based channel takes place. In the device and method, a heading portion MCS of the
scheduled channel following the contention based channel is set to be more tolerant
of errors (for example, QPSK, R=1/3) than the other portion MCS (for example,
16QAM, R=1/3) and transmission is carried out.
