Title:
TRANSMISSION METHOD AND TRANSMISSION DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/050833
Kind Code:
A1
Abstract:
According to a transmission power control signal including information on a
transmission power change amount ΔP, it is possible to decide whether
to perform mode switching between a compressed mode and a non-compressed mode
by referencing an output power level of a power amplifier (103) or to perform mode
switching between the compressed mode and the non-compressed mode without referencing
the output power level of the power amplifier (103). Thus, it is possible to operate
a measurement unit such as a detection circuit (106), an LPF (108), and an ADC (109)
only when substantially required. Accordingly, it is possible to suppress thefluctuation
(output power discontinuity) of the transmission power attributed to mode switching
with a low power consumption.
