ABSTRACT:
The present invention provides a method of controlling transmission power including the steps of: increasing transmission power immediately after a data transmission without waiting for a response signal to be received indicating a result of receiving the transmitted data; if the response signal received reveals that the transmitted data has been unsuccessfully received, retransmitting the same data and also holding transmission power applied when the data is retransmitted; if the response signal received reveals that the transmitted data has been successfully received and data previously transmitted has also been successfully received, reducing transmission power for a subsequent data transmission by a predetermined amount; and if the response signal received reveals that the data transmitted has been successfully received and data previously transmitted has been unsuccessfully received, setting transmission power for the subsequent data transmission depending on the transmission power held being applied when the data was retransmitted.
