APPARATUS AND METHOD FOR ADJUSTING TRANSMISSION POWER OF A TERMINAL IN A WIRELESS COMMUNICATION SYSTEM
First Claim
1. An apparatus for adjusting transmission power of a terminal wirelessly communicating with the apparatus, the apparatus comprising:
- a radio frequency (RF) processing circuit configured to receive, from the terminal, a communication request that includes a data amount value indicating an amount of transmission data held in the terminal;
a control circuit configured;
to obtain a predicted division count indicating a predicted number of frames to be used for transmitting the transmission data, based on the data amount value and a first bandwidth value indicating a predicted amount of bandwidth allocatable to the terminal,to obtain a first difference between a target value of reception quality of data to be received from the terminal and a measured value of reception quality of data that has been actually received from the terminal,to calculate an adjustment count value indicating a number of times the terminal is to be requested to adjust transmission power until the first difference falls to or below a threshold value, andto reduce an second bandwidth value indicating an amount of bandwidth to be actually allocated to the terminal when the predicted division count is smaller than the adjustment count value, so that the transmission data is transmitted by using as many frames as the adjustment count value; and
a memory configured to store data used for processing performed by the control circuit, whereinthe RF processing circuit transmits, to the terminal, an adjustment request for adjusting the transmission power of the terminal, together with the second bandwidth value, before the terminal transmits each of frames used for transmitting the transmission data.

Abstract
A base-station receives, from the terminal, a data-amount value of transmission-data held in the terminal, and obtains a predicted division-count indicating a predicted number of frames to be used for transmitting the transmission-data, based on the data-amount value and the amount of bandwidth allocatable to the terminal. The base-station obtains a difference between target and measured reception qualities of data from the terminal, calculates an adjustment-count value indicating a number of times the terminal is to be requested to adjust transmission-power until the difference falls to or below a threshold, reduces the amount of bandwidth to be actually allocated to the terminal when the predicted division-count is smaller than the adjustment-count value, so that the transmission-data is transmitted using as many frames as the adjustment-count value, and transmits, to the terminal, an adjustment request indicating the reduced amount of bandwidth, before the terminal transmits each frame.

4. A method for adjusting transmission power of a terminal wirelessly communicating with a base station, the method comprising:
-
receiving, by the base station, from the terminal, a communication request that includes a data amount value indicating an amount of transmission data held in the terminal; obtaining, by the base station, a predicted division count indicating a predicted number of frames to be used for transmitting the transmission data, from the data amount value and a first bandwidth value indicating a predicted amount of bandwidth allocatable to the terminal; obtaining, by the base station, a first difference between a target value of reception quality of data to be received from the terminal and a measured value of reception quality of data that has been actually received from the terminal; calculating, by the base station, an adjustment count value indicating a number of times the terminal is to be requested to adjust transmission power until the first difference falls to or below a threshold value; reducing, by the base station, when the predicted division count is smaller than the adjustment count value, an second bandwidth value indicating an amount of bandwidth to be actually allocated to the terminal so that the transmission data is transmitted by using as many frames as the adjustment count value; and transmitting, by the base station, to the terminal, an adjustment request for adjusting the transmission power of the terminal, together with the second bandwidth value, before the terminal transmits each of frames used for transmitting the transmission data. - View Dependent Claims (5)
