[0002] At present, the indoor distributed system uses coupling devices to divide the base station signal and distribute power. Among them, the downlink signal passes through the coupling device to reach the straight-through port and the coupling port respectively to achieve power distribution, and the overall signal energy loss is relatively small. However, there is a huge coupling loss in the process of the uplink signal being input from the coupling port and transmitted back to the remote radio unit (RRU) equipment of the base station. The equivalent straight-through end of the uplink signal is an isolation port. The overall capacity loss of the uplink signal backhaul is large, and it often faces coupling losses of multiple coupling devices, which makes it difficult to improve the indoor uplink coverage and rate.

[0030] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.

[0031] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.

[0032] It should be understood that the various steps described in the method embodiments of the present disclosure may be performed in different orders and / or in parallel. In addition, the method embodiments may include additional steps and / or omit the steps shown. The scope of the present disclosure is not limited in this respect.

[0033] It should be noted that the concepts such as "first" and "second" mentioned in the present disclosure are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0034] It should be noted that the modifications of "one" and "plurality" mentioned in the present disclosure are illustrative rather than restrictive, and those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0035] The indoor distribution system is a successful solution for indoor user groups to improve the mobile communication environment in buildings. It uses relevant technical means to evenly distribute the signals of mobile communication base stations in every corner of the room, thereby ensuring that the indoor area has ideal signal coverage.

[0036] A coupler is a power distribution device. The coupler couples a portion of the energy from the signal, and the coupled energy is often used for signal detection or monitoring. The use of a coupler in conjunction with a power divider is mainly to achieve one goal - to distribute the transmission power of the signal source as evenly as possible to each antenna port of the indoor distribution system, so that the transmission power of each antenna port is basically the same.

[0037] The important indicators of couplers are coupling degree and insertion loss. Coupling degree is the ratio of the power of the coupling port to the input port, and is generally a negative value when expressed in dB. The larger the absolute value of coupling degree is, the less things are taken away, and the loss of the coupler is naturally smaller. Insertion loss is the ratio of the power of the output port to the input port. The larger the absolute value of coupling degree is, the smaller the absolute value of insertion loss is. Insertion loss is the signal loss caused by inserting a cable or component, usually referred to as attenuation.

[0038] Combine the following Figure 1-Figure 7 , the coupling device, system, uplink signal equalization method, equipment, medium and product provided in the embodiments of the present disclosure are described.

[0039] Figure 1 A schematic diagram of a coupling device provided in an embodiment of the present disclosure is shown in FIG. Figure 1 As shown, the coupling device includes: a coupler 11, an energy unit 12 and a low noise amplifier unit 13;

[0040] The coupler 11 is used to perform power balancing processing on the input signal, and the coupler 11 includes: an input port 1, a coupling port 3, an output port 2 and an isolation port 4;

[0041] The low noise amplifier unit 13 is connected to the input port 1 of the coupler 11 and is used to amplify the input signal;

[0042] The energy unit 12 is connected to the isolation port 4 of the coupler 11 and the low noise amplifier unit 13 respectively, and is used for converting the radio frequency signal of the isolation port 4 into electrical energy and supplying power to the low noise amplifier unit 13 .

[0043] In the embodiment of the present disclosure, indoor signal branching is performed based on a coupling device, and the energy of the downlink signal is converted into electrical energy through an energy unit to power a low-noise amplifier unit for amplifying the uplink signal. In addition, the low-noise amplifier unit is arranged at the input port of the coupler, and the amplified signal does not undergo coupling loss. The energy utilization efficiency of signal amplification is higher, and the collected energy is fully utilized to enhance the uplink signal, effectively overcoming the problem of severe coupling loss when the uplink signal is returned, and effectively improving the uplink coverage and performance of the indoor distribution system.

[0044] Figure 2 A schematic diagram of another coupling device provided in an embodiment of the present disclosure, such as Figure 2 As shown, on the basis of the previous embodiment, the coupling device of the embodiment of the present disclosure further includes: an enabling unit 14, connected to the input port 1 of the coupler 11, and connected to the low noise amplifier unit 13, for enabling the control of whether the low noise amplifier unit 13 is turned on and working according to the uplink signal strength output from the input port 1 of the coupler 11. Among them, the enabling unit 14 enables the control of whether the low noise amplifier unit 13 is turned on and working according to the uplink signal strength output from the input port 1 of the coupler 11, so as to amplify only the weak uplink signal, which can maximize the efficiency of the use of the electric energy collected by the isolation port 4, make full use of the collected energy to enhance the uplink signal, and effectively improve the uplink coverage and performance of the indoor distribution system.

[0045] Figure 3 A schematic diagram of another coupling device provided in an embodiment of the present disclosure, such as Figure 3 As shown, based on the previous embodiment, the energy unit 12 in the coupling device of the embodiment of the present disclosure includes: an energy conversion subunit 121 and an energy storage subunit 122 .

[0046] The energy conversion subunit 121 is used to convert the radio frequency signal output from the isolation port 4 of the coupler 11 into electric energy; the energy storage subunit 122 is used to store the electric energy converted by the energy conversion subunit 121 and provide electric energy input for the low noise amplifier unit 13. A portion of the downlink radio frequency signal is coupled through the coupling device, and the energy of the downlink radio frequency signal is converted into electric energy through the energy conversion subunit 121 and stored in the energy storage subunit 122. The energy storage subunit 122 supplies power to the low noise amplifier unit 13 that amplifies the uplink signal, thereby achieving amplification of the uplink signal.

[0047] According to the working conditions provided in the above embodiment, taking a 10dB coupler as an example, the electrical parameters are as shown in Table 1 below, the RF signal electrical conversion efficiency is assumed to be 70%, the energy utilization rate of the LNA (low noise amplifier) ​​amplified signal is assumed to be 60%, and the coupling port input uplink signal power is 100mW (20dBm). In the prior art, the isolation port energy is 18.8dBm (based on 1.12dB insertion loss), considering the electrical conversion efficiency to restrain the power of the power supply unit is about:

[0048] 10*log(10^(18.88 / 10)*70%mW)=17.25dBm

[0049] The energy utilization of the uplink signal amplified by LNA is approximately:

[0050] 10*log(10^(17.25 / 10)*60%mW)=14.24dBm

[0051] Therefore, the signal power of the uplink 100mW power signal after LNA amplification is:

[0052] 10*log10(100mW+10^(14.24 / 10)mW)=21.02dBm

[0053] Then, the uplink power of the signal transmitted back from the input port after passing through the 10dB coupler is 11.02dBm (coupling degree deviation is 0). Compared with the uplink return signal power of 10dBm obtained at the input port without LNA amplification, it is only increased by 1.02dBm, which has limited improvement on the uplink signal.

[0054] Table 1- Common 10dB coupler electrical parameters

[0055]

[0056]

[0057] Based on the embodiment of the present disclosure, under the same assumptions, the signal power of the 20dBm (100mW) uplink signal transmitted back from the input port after passing through the coupler is 10dBm. Considering the electrical conversion efficiency and the energy utilization rate of the LNA amplified signal, the power of the LNA that can be used to amplify the uplink signal of the input port is still 14.24dBm. In the embodiment of the present disclosure, the uplink return signal power output after amplification by the LNA is:

[0058] 10*log10(10^(10 / 10)mW+10^(14.24 / 10)mW)=15.62dBm

[0059] Therefore, when the LNA amplifier is placed at the coupler input port, the returned uplink signal can be amplified by more than 5.62dB.

[0060] In addition, consider amplifying only the weak uplink signals in the edge area and not amplifying the stronger uplink signals. Since the edge area generally accounts for less than 40% of the cell, and the average power of the stronger uplink signals in the non-edge area is about 20dB stronger than that of the edge signals, the ratio of the energy collected by the uplink signals in the non-edge area at the coupler isolation end to the energy collected by the edge signals is approximately:

[0061] Non-edge signal energy / edge signal energy = 10*log(20 / 10)*0.6 / 0.4 = 3 times

[0062] Therefore, when only the weak uplink signal at the edge is amplified, the weak uplink return signal of the coupling device based on the embodiment of the present disclosure can be further improved by about 4.77dB. That is, the coupling device improves the weak uplink signal by more than 10dB, which is more efficient than the capacity utilization efficiency in the prior art.

[0063] In the embodiments of the present disclosure, the backhaul of the multi-port coupling device may also be improved, which can greatly improve the performance of the uplink signal of the MIMO (multiple-input multiple-output) indoor distributed system. Figure 4 A schematic diagram of another coupling device provided in an embodiment of the present disclosure, such as Figure 4 As shown, based on the previous embodiment, the coupling device of the embodiment of the present disclosure is a two-way orthogonal coupling device for realizing a MIMO dual-stream effect, and further includes: a first bridge unit 15 and a second bridge unit 16;

[0064] The first bridge unit 15 has a first bridge unit input port 151, a first bridge unit input port 2 152, a first bridge unit output port 153 and a first bridge unit output port 2 154, and the first bridge unit input port 2 152 is connected to the enabling unit 14;

[0065] The second bridge unit 16 has a second bridge unit input port 1 161 , a second bridge unit input port 2 162 , a second bridge unit output port 1 163 and a second bridge unit output port 2 164 . The first bridge unit output port 1 153 is connected to the second bridge unit input port 1 161 , and the second bridge unit input port 2 162 is connected to the output port 2 of the coupler 11 .

[0066] Further, the first-stage bridge unit 15 is an equally divided bridge;

[0067] Furthermore, the second-stage bridge unit 16 is an unequally divided bridge.

[0068] In the embodiments of the present disclosure, an energy conversion subunit, an energy storage subunit, and a low-noise amplifier with an enabling control function are added to the dual-path orthogonal coupling device that realizes the MIMO dual-stream effect, which can greatly improve the uplink signal transmission loss of the indoor distribution system, improve the uplink performance and the uplink dual-stream ratio. The energy collection and reuse amplification of the isolation port reduces the insertion loss of the coupling device from the coupling port backhaul uplink to the input port through the coupling device. In addition, only the power-sensitive edge weak uplink signal is amplified (the strong uplink signal in the center area has strong noise resistance, and the uplink performance gain after amplification is not obvious), which improves the utilization efficiency of the collected energy.

[0069] The disclosed embodiment also provides an indoor distribution system, comprising the coupling device described in any of the above embodiments.

[0070] Figure 5 A flowchart of an uplink signal equalization method provided by an embodiment of the present disclosure, such as Figure 5 As shown, the uplink signal equalization method of the embodiment of the present disclosure may include the following steps:

[0071] S51, inputting the uplink signal to be sent from the coupling port of the coupler to the coupler;

[0072] S52, amplifying the uplink signal output from the input port of the coupler by a low noise amplifier unit; wherein the low noise amplifier unit is powered by converting the radio frequency signal of the isolation port of the coupler into electrical energy by an energy unit.

[0073] In the embodiment of the present disclosure, indoor signal branching is performed based on a coupling device, and the energy of the downlink signal is converted into electrical energy through an energy unit, so that it powers a low-noise amplifier unit for amplifying the uplink signal; and, by setting the low-noise amplifier unit at the input port of the coupler, the collected energy is fully utilized to enhance the uplink signal, effectively overcoming the problem of severe coupling loss when the uplink signal is returned, and effectively improving the uplink coverage and performance of the indoor distribution system.

[0074] In some embodiments, further, the above step S51, amplifying the uplink signal output from the input port of the coupler by the low noise amplifier unit, comprises:

[0075] S511, determining whether the signal strength of the uplink signal outputted by the input port of the autocoupler is less than a first threshold;

[0076] According to a preset first threshold of the signal strength, it is determined whether the signal strength of the uplink signal is less than the first threshold, so that only the weaker uplink signal is amplified in the next step.

[0077] S512: When the signal strength is less than a first threshold, the enabling unit controls the low noise amplifier unit to turn on.

[0078] The uplink signal with a signal strength less than the first threshold is amplified, and the uplink signal with a signal strength greater than or equal to the first threshold is not amplified. In the embodiment of the present disclosure, by judging the signal strength of the uplink signal, it is possible to control whether the low noise floor amplifier unit is turned on, so that only the weaker uplink signal is amplified, which can maximize the efficiency of the power collected by the isolation port of the coupler.

It should be pointed out that a person skilled in the art can make several improvements, optimizations and modifications without departing from the principle of the present invention, and these should also be regarded as within the scope of protection of the present invention.
