Embodiment 1

[0041] This embodiment introduces a method for verifying the gain temperature characteristics of a base station, so as to solve the problem that the change in the gain temperature characteristics of radio frequency devices in each module of the base station cannot be found in the traditional technology. The temperature compensation value generally uses the data acquired by a small number of sample base stations as the compensation data of all base stations of the same type. However, as the production continues, changes in the batches of radio frequency components in the base station will cause changes in the overall gain temperature characteristics of the base station. In order to detect this change in time and deal with it, this embodiment uses the high-temperature aging environment of the base station to collect The uplink and downlink power detection values ​​obtain the temperature characteristics of the base station from normal temperature to high temperature range, and com...

Embodiment 2

[0054] This embodiment introduces a method for calibrating the gain temperature of the base station, such as Figure 4 As shown, including steps 210-230:

[0055] Step 210, obtaining the gain temperature change relationship corresponding to different areas of the sample base station in the high and low temperature environment;

[0056] Taking the multi-transmission and multi-reception base station as an example, the TRX (receiver board) and multiple PAs (power amplifiers) of the multi-transmission and multi-reception base station, such as Figure 5 As shown, the temperature of each region is different (the temperature difference near the PA is relatively large), and the corresponding gain temperature characteristics are also different. For example, for a 2T2R (two transmit and two receive) base station, there is one TRX (or two) and two PAs (referred to as PA1 and PA2). The temperature characteristics of the device gain within the device will also have a large difference. T...

Embodiment 3

[0078] This embodiment introduces a gain temperature compensation method of a base station, such as Figure 10 As shown, including steps 310-340:

[0079] Step 310, call the gain temperature compensation table corresponding to each area according to the current working temperature in different areas of the base station, and obtain the initial gain temperature compensation value corresponding to each area;

[0080] Step 320, call the gain temperature compensation table corresponding to each area according to the reference temperature of each area of ​​the base station corresponding to the current frequency point, and obtain the reference gain temperature compensation value corresponding to each area;

[0081] Step 330, calculating the difference between the initial gain temperature compensation value of each area of ​​the base station and the reference gain temperature compensation value of the area, as the gain temperature compensation value of each area;

[0082] Step 340: A...

Abstract

The invention discloses a base station gain temperature compensation, calibration and verification method and a compensation device. The gain temperature compensation method can solve the problem that the traditional method cannot accurately compensate the gain temperature characteristics of each area of ​​a multi-transmit and multi-receive base station, including: according to different areas of the base station Call the gain temperature compensation table corresponding to each area at the current working temperature to obtain the initial gain temperature compensation value corresponding to each area; call the gain temperature compensation table corresponding to each area according to the reference temperature of each area of ​​the base station corresponding to the current frequency point to obtain each area The base gain temperature compensation value corresponding to the area; calculate the difference between the initial gain temperature compensation value of each area of ​​the base station and the base gain temperature compensation value of the area, as the gain temperature compensation value of each area; the gain temperature compensation value of each area of ​​the base station The gain temperature compensation value of the entire base station is obtained by adding the values, and the gain temperature compensation value of the base station is used to compensate the gain temperature characteristic of the base station.

Description

technical field [0001] The invention relates to the field of mobile communication, in particular to a base station gain temperature compensation, calibration and verification method and compensation device. Background technique [0002] The gain of the radio frequency device of the base station will change with the change of the temperature. In the case of the same circuit structure, the greater the temperature change, the greater the change of the gain. After the gain is changed, for the downlink of the base station, the output power accuracy will decrease, which will affect the coverage area; for the uplink of the base station, the power detection accuracy will decrease, which will affect the rate of the user's uplink data service. Therefore, in order to control the uplink and downlink gains of the base station within a certain range, it is necessary to perform gain temperature characteristic compensation, so that when the base station works at different temperatures, the ...
