Abstract
A multiband wireless communication method for performing a reception operation in a second frequency band while performing a transmission operation in a first frequency band selectively changes a gain characteristic of a power amplifier (1 or 2) for performing the transmission operation so that gain is lowered in the second frequency band, based on performing of the reception operation.
Claims3
A multiband wireless communication method comprising:
- performing a transmission operation in a first frequency band with a first gain of a power amplifier, while not performing a reception operation in a second frequency band, that is different from the first frequency band;
- performing a transmission operation in the first frequency band with a second gain of the power amplifier, while performing the reception operation in a second frequency band;
- wherein
- the second gain is lower than the first gain, wherein
- when the reception operation is performed and a set transmission level of the power amplifier is above a transmission level threshold which is previously set, the second gain is set lower than the first gain, and wherein
- the transmission level threshold is set based on a data rate of a transmission signal by the power amplifier.

A multiband wireless communication apparatus comprising:
- a transmission unit configured to transmit a signal in a first frequency band and including a power amplifier, and
- a reception unit configured to receive a signal in a second frequency band that is different from the first frequency band
- a control unit configured to:
- set a first gain to the power amplifier while the transmission unit transmits a signal in the first frequency band and the reception unit does not receive a signal in the second frequency band, and
- set a second gain to the power amplifier while the transmission unit transmits a signal in the first frequency band and the reception unit receives a signal in the second frequency band,
- wherein the second gain is lower than the first gain, wherein
- when the reception unit receives the signal and the set transmission level of the power amplifier is above a transmission level threshold which the control unit previously set, the control unit sets the second gain lower than the first gain, and
- the control unit sets the transmission level threshold based on a data rate of a transmission signal by the power amplifier.
