Patent ID: 6871078

Claim:
A wireless communication device comprising: a control portion for setting data to be transmitted subjected to data transmission, and a level of transmission power for said data transmission; a transmitter for performing said data transmission with the level of transmission power set by said control portion; and a response signal determination portion for determining from an externally received signal whether said data transmission provides a successful transmission result or an unsuccessful transmission result, wherein said control portion i) after said data transmission has completed and before said transmission result is determined, increases a level of transmission power for a current data transmission by a first predetermined level to a first level of power to set a level of transmission power for a subsequent data transmission, and ii) if said response signal determination portion determines that said data transmission provides said successful transmission result, sets the level of transmission power for said subsequent data transmission to have a second level of power corresponding to said first level of power minus a second predetermined level, and wherein said second predetermined level is greater than said first predetermined level.
