Description

Technical Field

[0001] The present invention belongs to the field of communication technology, and in particular relates to a calculation method, a dynamic adjustment method, a device and a platform for input power of a multi-system combining platform. Background Art

[0002] In the field of mobile communications, with the coexistence of multiple standards, such as WCDMA, TD-SCDMA, TDD LTE, FDD LTE and 5G NR, operators usually use multi-system combined platforms (POI, Point of Interface) to solve indoor coverage problems in order to save construction costs and avoid duplication. However, with the access of multiple systems and multiple frequency bands, especially the simultaneous access of different high-power signals, intermodulation interference (IMI) problems are inevitable. This interference will not only lead to a decline in the network performance of the affected system, but also significantly affect the user experience, thereby reducing the overall service quality.

[0003] There are currently two main methods for dealing with interference caused by POI input. The first is to use separate uplink and downlink platforms to process uplink and downlink signals separately. In this solution, the downlink platform focuses on the downlink frequency band, while the uplink platform processes the uplink frequency band. When the downlink intermodulation interference happens to fall in the uplink frequency band, the downlink platform does not process the uplink frequency band, so it can effectively filter out the interference.

[0004] The second method is to use a duplex platform that can process uplink and downlink signals simultaneously and achieve interference processing by improving the intermodulation suppression index. Currently, the highest intermodulation suppression index of POI is -150dBc@2×43dBm.

[0005] Although the uplink and downlink separate transmission scheme performs well in reducing interference, the scheme cannot support the MIMO (Multiple Input Multiple Output) technology of mobile broadband, resulting in a decrease in network capacity (maximum rate of the cell) and insufficient utilization of wireless resources. When using a duplex platform, the -150dBc@2×43dBm POI faces greater challenges in an environment where multiple systems coexist. For example, in the same frequency band, China Unicom's 2100 band simultaneously opened LTE FDD (Frequency Division Duplex) and 5G NR (New Radio) cells. When the input power of the POI exceeds 43dBm, the intermodulation suppression performance will deteriorate significantly, causing the intermodulation interference level to become uncontrollable. Therefore, the inability to effectively control the input power of the POI makes the intermodulation interference level out of control, which has become a major shortcoming of using the -150dBc@2×43dBm POI solution. Summary of the invention

[0089] Embodiment 1:

[0090] like Figure 1 and Figure 2 As shown, this embodiment provides a method for calculating the input power of a multi-system combining platform, which is applicable to a variety of communication environments, including mobile communication base stations, wireless local area networks, satellite communications, the Internet of Things, emergency communications, and intelligent transportation systems. In these environments, the method can dynamically adjust the input power according to real-time network conditions and user needs to optimize signal quality, reduce interference, and improve resource utilization efficiency, thereby ensuring the stability and reliability of communication.

[0091] The method comprises the following steps: first, receiving an input RF signal and performing signal coupling to obtain a coupled signal and a direct signal, then detecting the power intensity in the coupled signal and determining whether it exceeds the maximum power threshold configured by the network management; if it exceeds, performing attenuation control and calculating the power attenuation value; if it does not exceed, not performing attenuation control. Finally, according to the calculated power attenuation value, adjusting the output power of the direct signal, and using it as the input power of the multi-system combining platform, thereby realizing dynamic adjustment of the input power.

[0092] Specifically, the RF signal (radio frequency signal) in the received input RF signal refers to an electromagnetic wave signal with a frequency range of 3kHz to 300GHz, which is widely used in wireless communications, broadcasting, radar, satellite communications and other fields. It can be transmitted through the air, has strong penetration ability, supports multiple modulation methods to transmit information, and is the basis of modern communication systems. Receiving the input RF signal means that the system first obtains the external RF signal, which may come from different communication sources, such as mobile base stations, wireless devices or other signal transmitters.

[0093] As a specific implementation manner, the receiving of input RF signals specifically includes: receiving input mobile communication signals, and / or, receiving input satellite communication signals, and / or, receiving input broadcast signals, and / or, receiving input wireless access signals, and / or, receiving input Internet of Things signals, and / or, receiving input radar signals, and / or, receiving input sensor signals.

[0094] The input RF signal is coupled to obtain a coupled signal and a direct signal. The process of coupling the input RF signal is to divide the received RF signal into two parts through a specific coupler or distributor: one part is the coupled signal and the other part is the direct signal. The coupled signal is usually used for monitoring and analysis for power detection and signal quality evaluation, while the direct signal is directly transmitted to the subsequent processing unit. Through this coupling method, the system can simultaneously obtain the real-time status of the signal and perform effective signal transmission, thereby achieving comprehensive management and optimization of the signal.

[0095] Detecting the power intensity in the coupled signal means using a power meter or other measuring equipment to monitor the power level of the coupled signal obtained from the coupler in real time. The process involves inputting the coupled signal into the power detection circuit and accurately measuring the power intensity of the signal through appropriate sensors or measuring instruments. This detection not only provides the power value of the current signal, but also helps identify the changing trend of the signal and ensure that the signal strength is within the predetermined range, thereby providing the necessary data support for subsequent power adjustment and system optimization. Through this detection, the system can respond to changes in signal strength in a timely manner to ensure communication quality and system stability.

[0096] The maximum power threshold configured by the network management system refers to a key parameter preset in the network management system to limit the power strength of the input signal to ensure the security and stability of the system. This threshold is usually configured by the network administrator based on the performance of the equipment, environmental conditions and communication requirements, in order to prevent equipment damage, intermodulation interference or signal distortion caused by excessive signal strength. By setting this threshold, the system can automatically trigger the corresponding control mechanism, such as attenuation control, to maintain the signal within a safe range when the received RF signal power exceeds this value, thereby ensuring the normal operation of the network and the quality of communication.

[0097] Determine whether the detected power intensity exceeds the maximum power threshold configured by the network management:

[0098] If the detected power intensity exceeds the maximum power threshold value configured by the network management, attenuation control is performed and the power attenuation value is calculated; if the detected power intensity does not exceed the maximum power threshold value configured by the network management, no attenuation control is performed;

[0099] Calculating the attenuated through signal output power according to the power attenuation value;

[0100] In specific implementation, the power attenuation value P attenuation The calculation of is as follows:

[0101] P attenuation =P test -P limit ;

[0102] Where P test is the detected power intensity, P limit The maximum power threshold value configured for the network management. In specific implementation, in addition to the calculation formula of the power attenuation value, other methods can also be used for evaluation, such as determining the attenuation value based on signal quality indicators (such as signal-to-noise ratio) or through empirical models. These methods may take into account different environmental factors and system characteristics, but the reason for choosing the above formula is its simplicity and directness. This formula can clearly reflect the difference between the actual detected power intensity and the preset maximum power threshold value, facilitate rapid calculation and real-time adjustment, ensure that the system operates within a safe range, thereby effectively preventing signal overload and interference, and improving the stability and reliability of the system.

[0103] The through signal output power P output The calculation of is as follows:

[0104] P output =P input -P attenuation ;

[0105] Where P input is the power intensity of the input RF signal.

[0106] In addition to this calculation method based on input power and power attenuation values, the through signal output power can also be estimated by measuring the power of the actual output signal or using complex signal processing algorithms. However, the above formula is chosen because of its intuitiveness and ease of implementation. This formula can quickly and accurately reflect the actual output power of the input signal after attenuation, which is convenient for real-time monitoring and adjustment, ensuring the stability and quality of the signal during transmission. At the same time, it simplifies the calculation process and is suitable for application in dynamic adjustment systems.

[0107] To better illustrate the dynamic adjustment process of this embodiment, the following is a specific example of this method, including numerical descriptions:

[0108] (1) Receive input RF signal:

[0109] Assume that the received RF signal power is 10dBm.

[0110] (2) Signal coupling:

[0111] Through signal coupling, a coupled signal and a direct signal are obtained. Assume that the power of the coupled signal is 8dBm and the power of the direct signal is 10dBm.

[0112] (3) Detect the power intensity in the coupled signal:

[0113] The detected coupled signal power is 8dBm.

[0114] (4) Determine whether the power intensity exceeds the maximum power threshold:

[0115] Assume that the maximum power threshold configured by the network management is 7dBm.

[0116] Since 8dBm exceeds the threshold of 7dBm, attenuation control is required.

[0117] (5) Perform attenuation control and calculate the power attenuation value:

[0118] Assume that the power of the coupled signal needs to be reduced to a maximum threshold value of 7dBm.

[0119] Calculate the power attenuation value:

[0120] Power attenuation value = 8dBm-7dBm = 1dBm

[0121] (6) Adjust the output power of the direct signal:

[0122] According to the calculated power attenuation value 1dBm, adjust the output power of the through signal.

[0123] Assuming the original through signal power is 10dBm, the adjusted output power is

[0124] =10dBm-1dBm=9dBm

[0125] (7) The adjusted direct signal output power is used as the input power of the multi-system combining platform:

[0126] Finally, the adjusted through signal output power of 9dBm is used as the input power of the multi-system combining platform.

[0127] Using the attenuated through-signal output power as the input power of the multi-system combining platform means that after the power attenuation process, the system will re-input the calculated output power value into the combining platform to replace the original input signal power. This process ensures that the combining platform can dynamically adjust its input power according to the real-time signal strength, thereby optimizing the signal transmission quality and the overall performance of the system. Through this dynamic adjustment, the combining platform can effectively respond to different network conditions and user needs, avoid interference and signal distortion caused by too strong or too weak signals, and ensure the coordination and stability of communication between various systems. This method not only improves the utilization efficiency of resources, but also enhances the user's communication experience.

This input power is then used as a dynamic adjustment value to adjust the input power of the multi-system combining platform, aiming to enhance its anti-interference ability. Through this dynamic adjustment, the system can automatically optimize the input power in a fluctuating environment, thereby effectively reducing the impact of interference on signal transmission and ensuring the stability and reliability of the system under various working conditions.
