Apparatus and method for changing data transmission schemes

摘要

A communication device and methods are disclosed. A first throughput is calculated when a current modulation scheme and a current encoding rate is changed, and a second throughput is calculated when a current retransmission unit is changed. The current modulation scheme and the current encoding rate are changed to provide a changed modulation scheme and a changed encoding rate, if the first throughput is greater than or equal to the second throughput when prescribed conditions are met. The current retransmission unit is changed to provide a changed retransmission unit, if the first throughput is less than the second throughput. Information is transmitted to a communication device of a communication partner based on the changed modulation scheme, the changed encoding rate, and the changed retransmission unit.

1. A communication device comprising:
at least one processor, wherein the at least one processor comprises:
a first calculating module operable to calculate a first throughput corresponding to a current modulation scheme and a current encoding rate being changed in the future;a second calculating module operable to calculate a second throughput corresponding to a current retransmission unit being changed in the future;a setting module operable to:
compare the first throughput with the second throughput;change the current modulation scheme and the current encoding rate if the first throughput is greater than or equal to the second throughput; orchange the current retransmission unit if the first throughput is less than the second throughput; anda transmission module operable to transmit data based on the changed modulation scheme and the changed encoding rate if the first throughput is greater than or equal to the second throughput, or the changed retransmission unit if the first throughput is less than the second throughput.
