Title:
MOBILE COMMUNICATION TERMINAL TRANSMISSION POWER CONTROL METHOD AND MOBILE COMMUNICATION TERMINAL TRANSMISSION POWER CONTROL DEVICE
Document Type and Number:
WIPO Patent Application WO/2008/053845
Kind Code:
A1
Abstract:
A transmission power increasing section repetitively transmits a transmission power
increase request from a tester to increase the transmission power of the mobile
communication terminal by a predetermined value to the mobile communication terminal
at predetermined intervals. A block size extracting section receives physical
channels from the mobile communication terminal at every transmission of a transmission
power increase request and extracts block size information representing the
transmittable data block size determined according to the maximum transmission
power set for a first physical channel from a predetermined second physical channel.
A storage section stores the block size information acquired at least by one
extraction by the block size extracting section. A maximum output power state
determining section compares the value of the newly extracted block size information
with the immediately previous block size information stored in the storage section,
stops the transmission power increasing section to transmit the transmission
power increase request if the value of the newly extracted block size information
is smaller than that of the immediately previous block size information stored
in the storage section, and transmits a transmission power decrease request
to decrease the transmission power of the mobile communication terminal by a
predetermined value.
