Method and device for regulating calibration transmission power

Abstract

The invention discloses a method for adjusting and calibrating transmission power. The method comprises the following steps: receiving noise signals within the interval when a calibrating antenna periodically transmits the calibrating signals; calculating an average noise power of all the noise signals and calculating a minimal calibration transmission power required for the normal work state of the calibrating antenna according to the average noise power; and adjusting the current calibration transmission power of the calibrating antenna according to the minimal calibration transmission power. Therefore, during the process of detecting the radio-frequency channel of a communication device, the method adjusts the calibration transmission power of the calibrating antenna in real time according to the environmental noise interference, thereby ensuring the transmission strength of the calibrated signal, allowing the transmission strength of the calibrated signal to meet the specified signal-to-noise ratio of system, improving the accuracy of the detection result, ensuring the coverage and the business quality of the system signal, and improving the user experience. The invention alsodiscloses an adjusting device and a base station.

Description

technical field [0001] The present invention relates to the communication field, in particular to a method and device for adjusting and calibrating transmission power. Background technique [0002] In an existing communication system, a communication device usually uses a periodic calibration method to detect its own radio frequency channel for transmitting radio frequency signals, so as to correctly evaluate the channel quality of each radio frequency channel. During the detection process, the calibration antenna on the communication device periodically transmits calibration signals according to the preset fixed calibration power (also called calibration transmission power), and the working antenna on the communication device receives the calibration signals sent by the calibration antenna through each radio frequency channel. signal, and after processing the calibration signal, evaluate the quality of the radio frequency channel transmitting the calibration signal accordi...

Problems solved by technology

[0003]However, when the periodic calibration method is used to detect each RF channel, if there is strong external noise interference, the preset calibration transmission power is used to transmit the calibration signal Will not be able to meet the specified system signal to noise ratio (Signal to Interfrence Ratio, SIR), resulting in inaccurate test results

If the quality of each radio frequency channel is evaluated based on inaccurate detection results, wrong channel quality information will be obtained, which will affect system signal coverage and service quality, thereby affecting user experience
