Title:
WIRELESS COMMUNICATION METHOD AND APPARATUS THEREOF
Document Type and Number:
WIPO Patent Application WO/2008/053731
Kind Code:
A1
Abstract:
A wireless communication method wherein a wireless communication apparatus adaptively
selects one of modulation schemes to have wireless communication with a wireless
communication apparatus at the other end. The wireless communication method
comprises the steps of grasping the quality of a received signal; selecting, based
on the grasped quality of the received signal, a first modulation scheme; calculating
a retransmittal rate of the received signal in the first modulation scheme; determining,
based on the association between a throughput and the calculated retransmittal
rate, an estimated throughput from the retransmittal rate; comparing the determined
estimated throughput with the throughput of a second modulation scheme having
a smaller number of multi-levels than the first modulation scheme; and using,
in accordance with a result of the comparison, the first or second modulation scheme
to have wireless communication.
