Embodiment Construction
[0074] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0075] The inner loop power control is specifically, the base station compares the SIR (Signal to Interference Ratio, signal to interference ratio) of the received signal with the target SIR, and then sends a power control command to the user terminal according to the comparison result, and then the user terminal according to the received The power control command increases or decreases its own transmit power, so that the receiving SIR of the base station converges ...

The invention discloses a method and a system for optimizing the inner loop power control of a terminal. The method comprises the following steps: acquiring a current inner loop power control error point, and judging whether the error point is located in a preset range near a power amplifier (PA) switching point or not; if so, determining whether the current relative value increases or decreases or not, wherein the relative value is a change value of actual power when the inner loop power control is 1dB; if the current relative value increases or decreases, carrying out temperature compensation, and setting the current temperature compensation value as a best temperature compensation value matched with the current temperature when the current powder of the current error point meets a preset requirement of the inner loop power control; if current relative value does not increases or decreases, carrying out switching point compensation on the PA switching point, and setting the current switching point compensation value as a best switching point compensation value matched with the PA switching point when the current powder of the current error point meets the preset requirement of the inner loop power control. The method and the system can optimize the indexes of the inner loop power control in a targeted way, and determine a compensation value of the inner loop power control of the terminal, thus enabling the terminal to accurately perform the inner loop power control and improving the service quality of the terminal.
Description
technical field [0001] The present invention relates to the field of communication technology, in particular to an optimization method and system for terminal inner loop power control. Background technique [0002] The growth of demand for high-speed mobile data transmission has prompted the rapid popularization of mobile communication 3G system applications. CDMA2000, WCDMA, TD-SCDMA and WiMAX, which are the four major standards of the 3G system, all belong to the CDMA system except WiMAX. [0003] In the WCDMA (Wideband Code Division Multiple Access) mobile communication system, multiple users share a transmission channel according to certain rules. Due to the phenomenon of signal attenuation and multipath interference, the transmission power of different user terminals It will directly affect the total capacity of the system. Therefore, in order to allow user terminals to obtain acceptable service quality with the minimum transmit power corresponding to the current wirel...
