Problems solved by technology

In this case, the base station cannot restore the signal of terminal B
To sum up, when the two terminals A and B are at different distances from the base station and send signals to the base station at the same time with the same power level, there will be such a problem: the base station cannot recover the signal received from the terminal B that is far away from it. Signal
There is such a problem here: when the decibel value (dB) of the signal is high, the output value increases with the rise of temperature, and when the decibel value (dB) of the signal is low, the output value decreases with the rise of temperature
In this case, however, there arises a problem of increased memory capacity during use

Embodiment Construction

[0025] Let us now look more closely at some of the preferred embodiments of the present invention. In the following description of the invention, numerous specific details are set forth in order to provide a fuller understanding of the invention. However, it will be apparent to those skilled in the art that the present invention may be practiced otherwise than in the specific details described above. Known functions and constructions involved in the present invention are not described in detail when it may obscure the subject matter of the present invention.

[0026] Figure 4 is the code for output power magnitude in figure 2 The temperature change curve when the temperature is set at 100% as the reference value.

[0027] see Figure 4 , the upper left -55 dB output value (42) is compared with the reference level (the difference "19" between the reference level and the 24 dB output value at a temperature of 100), resulting in a difference of 23 codes. The lower left 24d...

Abstract

Disclosed is a method of controlling electric power according to a temperature compensation for a wireless communication terminal including a memory for storing each of code values of a maximum and minimum power according to a temperature variation and each of weight values for sending power, comprising the steps of; (a) calculating a compensation value at an associated sending power according to a reference temperature; (b) calculating a basic code value at an associated sending power according to a reference temperature; and (c) obtaining a compensated code value by adding the compensation value to the basic code value.

Description

technical field [0001] The present invention relates to electric power control of wireless communication terminals, more specifically, relates to a control rule system for compensating losses according to temperature changes in wireless communication terminals. Background technique [0002] Generally, wireless communication terminals are designed to be controlled according to changes in the distance between them and a base station. The power required for transmission by a wireless communication terminal increases as it moves away from the base station, and decreases as it approaches the base station. In fact, the transmission power of the wireless communication terminal should be controlled so that it is inversely proportional to the received signal strength indicator (RSSI) measured at the wireless communication terminal. [0003] For example, wireless communication terminal A is 100 meters away from the base station, and wireless communication terminal B is 1 km away from...
