Classification: H04W

Abstract:
A transmission/reception apparatus comprising:detecting means for detecting a received quality of a received signal; reading means for reading a symbol and an amplitude of a TPC bit in the received signal; control means for multiplexing the TPC bit with a transmission signal and setting an amplitude of said transmission signal for each bit; and transmitting means for transmitting said transmission signal with the amplitude set in said control means, wherein said control means comprises symbol setting means for setting the symbol of the TPC bit; TPC bit amplitude setting means for setting the amplitude of the TPC bit; and general amplitude setting means for setting the amplitude of a bit other than the TPC bit in the transmission signal, and wherein said symbol setting means sets the symbol using an output from said difference calculating means, and said TPC bit amplitude setting means sets the amplitude using an output from said ratio calculation means.
