Description

Technical Field

[0002] At present, the traditional indoor distributed coverage system in the building is generally composed of N signal sources, a combiner / multi-system combining platform (Point of Interface, POI) and a coverage subsystem. As the number of signal sources increases, the operating frequencies of the signal sources increase, and the possibility that the passive third-order intermodulation signal (3rd Oder Passive Inter-Modulation, 3rd-PIM) generated by the combined signal falls into the operating frequency range of some of the signal sources is increasing. In particular, when the passive third-order intermodulation signal after combining falls into the uplink operating frequency range of some of the signal sources, it will cause uplink interference to the corresponding signal source, thereby raising the noise floor of the signal source, deteriorating the signal-to-noise ratio of the uplink signal, causing the bit error rate of the uplink to rise, and ultimately affecting the communication between the signal source and the terminal, and the entire indoor distributed coverage system cannot work normally.

[0049] Step 103: Generate design information of an indoor distributed coverage system based on the category labels of the N information sources, wherein the design information includes design parameters of the indoor distributed coverage system.

[0050] Specifically, the design parameters of the indoor distributed coverage system may be relevant working parameters of the devices of the indoor distributed coverage system. In an embodiment of the present invention, the information generation method classifies the N signal sources to obtain a category label for each signal source, and then designs the indoor distributed coverage system according to the category label to avoid the third-order intermodulation interference signal generated by the combined signal source from causing uplink interference to the signal source, so that the communication effect between the N signal sources and the terminal is better, thereby improving the communication effect of the entire indoor distributed coverage system.

[0051] Optionally, the N signal sources include S first target signal sources and M second target signal sources, the first target signal sources include the interfering signal sources and the unaffected signal sources, and the second target signal sources include the interfering signal sources and the interfered signal sources; the S first target signal sources are connected to the input end of the first front coverage subsystem through a first combiner; the M second target signal sources are respectively connected to the input ends of the M second front coverage subsystems in a one-to-one correspondence to form M transmission lines; the output end of the first front coverage subsystem and the output ends of the M second front coverage subsystems are respectively connected to the input end of the target coverage subsystem through a second combiner, S and M are integers greater than or equal to 0; the design information includes M+1 minimum insertion loss values ​​corresponding to the M+1 front coverage subsystems, the M+1 front coverage subsystems include the first front coverage subsystem and the M second front coverage subsystems, and the design information of the indoor distributed coverage system is generated based on the category labels of the N signal sources, including:

[0052] Based on the insertion loss of the first combiner, the insertion loss of the second combiner, the N output powers and N maximum uplink interference levels corresponding to the N signal sources, and the third-order intermodulation index of the target coverage subsystem, the M+1 minimum insertion loss values ​​corresponding to the M+1 front coverage subsystems are determined, and the design information includes the M+1 minimum insertion loss values.

[0053] Specifically, the first target signal source may be a signal source that can be combined by the first combiner, the second target signal source may be a signal source that is individually connected to the M second front coverage subsystems in a one-to-one correspondence, the first combiner may be a device or POI that synthesizes the signals output by the interfering signal source and the non-affecting signal source and outputs them through one port, the second combiner may be a device or POI that synthesizes the signals output by the first front coverage subsystem and the M second front coverage subsystems and outputs them through one port, the front coverage subsystem may be an indoor coverage system whose signal coverage area is smaller than the required total signal coverage area, the first front coverage subsystem may be the front coverage subsystem connected to the first combiner, the second front coverage subsystem may be the front coverage subsystem connected to the second target signal source in a one-to-one correspondence, the maximum uplink interference level may be the highest noise floor required by the signal source system, the third-order intermodulation index may be the strength of the third-order intermodulation interference signal, and the minimum insertion loss value may be the minimum insertion loss values ​​corresponding to the M+1 front coverage subsystems that meet the noise floor requirements of the N signal source systems.

[0054] In an embodiment of the present invention, the information generation method can determine the minimum insertion loss values ​​corresponding to the M+1 front coverage subsystems respectively through the insertion loss of the first combiner, the insertion loss of the second combiner, the N output powers and N maximum uplink interference levels corresponding to the N signal sources respectively, and the third-order intermodulation index of the target coverage subsystem, so that after the N signal source signals are attenuated by the M+1 front coverage subsystems respectively, the signal strength of the third-order intermodulation signal generated at the target coverage subsystem and returned to the interfered signal source through the combiner and the front coverage subsystem does not exceed the maximum background noise required by the signal source system, thereby achieving better communication effect between the N signal sources and the terminal.

[0055] Optionally, the determining the M+1 minimum insertion loss values ​​corresponding to the M+1 front coverage subsystems respectively based on the insertion loss of the first combiner, the insertion loss of the second combiner, the N output powers and N maximum uplink interference levels respectively corresponding to the N signal sources, and the third-order intermodulation index of the target coverage subsystem includes:

[0056] Determine the first average input power of the signals of the S first target signal sources in the target coverage subsystem based on the N output powers respectively corresponding to the N signal sources, the insertion loss of the first combiner, the insertion loss of the second combiner, and the M+1 minimum insertion loss value parameters respectively corresponding to the M+1 front coverage subsystems;

[0057] Determine a first signal strength of the third-order intermodulation signal generated by the S first target information sources based on the first average input power, the insertion loss of the first combiner, the third-order intermodulation index of the target coverage subsystem, and the M+1 minimum insertion loss value parameters;

[0058] The M+1 minimum insertion loss values ​​are determined based on the first signal strength and the N maximum uplink interference levels respectively corresponding to the N information sources, and the M+1 minimum insertion loss values ​​are values ​​of the M+1 minimum insertion loss parameters.

[0059] Specifically, for example, Figure 2 is one of the structural diagrams of an indoor distributed coverage system provided by an embodiment of the present invention, such as Figure 2 As shown, assuming that N information sources include information source 1, information source 2 and information source 3, information source 1 and information source 2 are the interfering information sources, and information source 3 is the interfered information source, then the signals of information source 1 and information source 2 are combined through the first-level combiner / POI and input into the same front-end coverage subsystem 1, and the signal of information source 3 is connected to the second-level combiner / POI after passing through the front-end coverage subsystem 2, and the signals of the front-end coverage subsystem 1 and the front-end coverage subsystem 2 are combined through the second-level combiner / POI, and the combined signals are input into the final coverage subsystem S, i.e., the target coverage subsystem;

[0060] Assuming that the output power of source 1 and source 2 are P1 and P2 respectively, the average input power reaching point B of the final coverage subsystem S is:

[0061]

[0062] Among them, the power of the output signal of source 1 at point B is P1-L1-L com1 -L com2 (Unit: dBm), the power of the output signal of source 2 at point B is P2-L1-L com1 -L com2 (Unit: dBm), P ave is the average input power of the two signals at point B, L com1 and L com2 are the insertion losses of the first-stage combiner / POI and the second-stage combiner / POI, respectively. PIM2 is the third-order intermodulation value (in dBc) of the final coverage subsystem S under the condition of 2×43dBm. Because the final coverage subsystem S is generally more complex in structure, with more components and connectors, and has higher requirements on construction technology, and considering the difficulty of on-site construction and the difficulty of construction workers to achieve the ideal level of construction technology, the overall third-order intermodulation index of the final coverage subsystem S is poor, and the value is generally between -90dBc and 110dBc.

[0063] There are two ways to express the third-order intermodulation index: absolute value and relative value. The absolute value expression refers to the absolute value of the third-order intermodulation signal in dBm. The relative value expression refers to the ratio of the third-order intermodulation signal to one of the input frequency signals, also known as third-order intermodulation suppression, expressed in dBc. The typical passive intermodulation index is that when two 43dBm frequency powers act on the device under test DUT at the same time, the DUT generates a passive third-order intermodulation distortion of -110dBm (absolute value), and its relative value is -153dBc@2×43dBm.

[0064] For every 1dB increase in the input frequency signal, the absolute value of the third-order intermodulation signal increases by 3dB, that is, the relative value of the third-order intermodulation value increases by 2dB. Similarly, for every 1dB decrease in the input frequency signal, the absolute value of the third-order intermodulation signal decreases by 3dB, that is, the relative value of the third-order intermodulation value decreases by 2dB.

[0065] Therefore, if P ave >43dBm, then P ave For every 1dB increase, the third-order intermodulation suppression decreases by 2dB:

[0066] P interfere =P ave -L com2 -L2+PIM2+2×(P ave -43)

[0067] If P ave <43dBm, then P ave For every 1dB below the limit, the third-order intermodulation suppression increases by 2dB:

[0068] P interfere =P ave -L com2 -L2+PIM2-2×(43-P ave )

[0069] After comprehensive consideration, the above formula can be combined into:

[0070] P interfere =P ave -L com2 -L2+PIM2+2×(P ave -43)

[0071] Assume that the maximum uplink interference level allowed by the system of source 3 is P IoT , then P should be interfere <P IoT , that is, P ave -L com2 -L2+PIM2+2×(P ave -43)<P IoTFor the sake of simplicity, assume that P1 = P2 = P = 43dBm and L1 = L2 = L, that is, the front cover subsystem 1 and the front cover subsystem 2 have the same insertion loss, and P ave =PLL com1 -L com2 , the above announcement can be expanded as follows:

[0072] PLL com1 -L com2 -L com2 -L+PIM2-2×(L+L com1 +L com2 )<P IoT

[0073] PP IoT -4L com2 -3L com1 +PIM2<4L

[0074] L>(P-4L com2 -3L com1 +PIM2-P IoT ) / 4

[0075] It can be obtained that the insertion loss L of the front cover subsystem 1 and the front cover subsystem 2 should be greater than (P-4L com2 -3L com1 +PIM2-P IoT ) / 4;

[0076] Assume P = 43dBm; L com1 =1DB;L com2 =6dB; P IM2 =-100dBc; P IoT =-110dBm, then L>26 / 4dB, that is, the insertion loss L of the front coverage subsystem 1 and the front coverage subsystem 2 is not less than 6.5dB, that is, the minimum insertion loss value of the front coverage subsystem 1 and the front coverage subsystem 2 is 6.5dB.

[0077] In an embodiment of the present invention, the information generation method can reduce the first average input power of the signal of the target signal source in the target coverage subsystem so that the signal strength of the third-order intermodulation signal generated at the target coverage subsystem and returned to the interfered signal source through the combiner and the front coverage subsystem does not exceed the maximum background noise required by the signal source system, thereby determining the M+1 minimum insertion loss values ​​corresponding to the M+1 front coverage subsystems, respectively, so that the cost of building an indoor coverage system is lower.

[0078] Optionally, when S is less than or equal to 1, the N signal sources are respectively connected to the input ends of the N front coverage subsystems in one-to-one correspondence, the N front coverage subsystems are connected to the input end of the target coverage subsystem through a third combiner, the N front coverage subsystems include a first front coverage subsystem and N-1 second front coverage subsystems, the design information includes N minimum insertion loss values ​​corresponding to the N front coverage subsystems, and the design information of the indoor distributed coverage system is generated based on the category labels of the N signal sources, including:

[0079] Based on the insertion loss of the third combiner, the N output powers and N maximum uplink interference levels corresponding to the N signal sources, and the third-order intermodulation index of the target coverage subsystem, the N minimum insertion loss values ​​corresponding to the N front coverage subsystems are determined, and the design information includes the N minimum insertion loss values.

[0080] Specifically, S is less than or equal to 1, which may mean that the interfering signal source or the unaffected signal source does not exist among the N signal sources, or that there is only one interfering signal source or one unaffected signal source among the N signal sources. The third combiner may be a device or POI that synthesizes the signals output by the N front coverage subsystems and outputs them through one port.

[0081] In an embodiment of the present invention, the information generating method connects the N information sources to the input ends of the N front coverage subsystems one-to-one, and determines the minimum insertion loss values ​​corresponding to the N front coverage subsystems according to the insertion loss of the third combiner, the N output powers corresponding to the N information sources and the N maximum uplink interference levels, and the third-order intermodulation index of the target coverage subsystem, so that after the N signal sources are attenuated by the N front coverage subsystems, the signal strength of the third-order intermodulation signal generated at the target coverage subsystem and returned to the interfered signal source does not exceed the highest background noise required by the signal source system, thereby achieving better communication effect between the N signal sources and the terminal.

[0082] Optionally, determining N minimum insertion loss values ​​corresponding to the N front coverage subsystems respectively based on the insertion loss of the third combiner, the N output powers and N maximum uplink interference levels respectively corresponding to the N signal sources, and the third-order intermodulation index of the target coverage subsystem includes:

[0083] Based on the N output powers respectively corresponding to the N signal sources, the insertion loss of the third combiner and the N minimum insertion loss parameters respectively corresponding to the N front coverage subsystems, respectively determine P second average input powers of signals of any two signal sources among the N signal sources in the target coverage subsystem, where P is a positive integer;

[0084] Based on the P second average input powers, the insertion loss of the third combiner, the third-order intermodulation index of the target coverage subsystem, and the N minimum insertion loss values ​​respectively corresponding to the N front coverage subsystems, respectively determine P second signal strengths corresponding to the third-order intermodulation signals generated by signals of any two of the N information sources;

[0085] Based on the P second signal strengths and the N maximum uplink interference levels respectively corresponding to the N information sources, N minimum insertion loss values ​​respectively corresponding to the N front coverage subsystems are determined, and the minimum insertion loss values ​​are the values ​​of the N minimum insertion loss parameters.

[0086] Specifically, for example, Figure 3 FIG. 2 is a second structural diagram of an indoor distributed coverage system provided by an embodiment of the present invention. Figure 3 As shown in the figure, assuming that the third-order intermodulation signal generated by combining any two signals from source 1, source 2, ... source N will fall within its own uplink operating frequency range, then these N sources cannot be combined directly, and the N sources are connected to the N front-end coverage subsystems one by one, and the N front-end coverage subsystems are connected to the final coverage subsystem S, i.e., the target coverage subsystem, through the combiner / POI;

[0087] The front coverage subsystem 1 and the front coverage subsystem 2 are similar to the final coverage subsystem S, and are also indoor coverage systems. They are also composed of numerous devices (feeders, couplers, power dividers, connectors, antennas), and can achieve the purpose of coverage within the building. Although the third-order intermodulation indicators of the front coverage subsystem 1 and the front coverage subsystem 2 may also be poor (for example, around -100dBc), since the front coverage subsystem 1 only has the working frequency f1~f2 of the signal source 1, and does not have the working frequency f3~f4 of the signal source 2, even if a third-order intermodulation interference signal source is generated, it will not fall within the uplink working frequency range of the signal source 1 or the signal source 3, so it will not cause uplink interference to the signal source 1 or the signal source 3; similarly, since the front coverage subsystem 2 only has the working frequency f3~f4 of the signal source 2, and does not have the working frequency f1~f2 of the signal source 1, it will not cause uplink interference to the signal source 2 or the signal source 3, so in this case, the location where the third-order intermodulation signal is generated is still at point B of the final coverage subsystem S;

[0088] Assume that the output power of source 1 and source 2 are P1 and P2 respectively, the insertion loss of front coverage subsystem 1 and front coverage subsystem 2 are L1 and L2 respectively, the signals of source 1 and source 2 pass through front coverage subsystem 1 and front coverage subsystem 2 respectively, and then pass through combiner / POI to reach point B of the final coverage subsystem S. Assume that point B is the worst point of third-order intermodulation of the final coverage subsystem S, the insertion losses of front coverage subsystem 1, front coverage subsystem 2, front coverage subsystem N, and combiner / POI are L1, L2, LN , L com ;

[0089] For the convenience of calculation, it is assumed that the third-order intermodulation signal generated by the operating frequency of source 1 and the operating frequency of source 2 generates uplink interference to source 2 and source N, and then source 1 is the interfering source, source 2 is the interfering source, and source N is the interfered source, that is, the two-way signals fc1 and fc2 of source 1 and source 2 generate a third-order intermodulation signal fc3 at point B, which falls within the uplink operating frequency range of source N, and the two-way signals fc1' and fc2' of source 1 and source 2 generate a third-order intermodulation signal fc3' at point B, which falls within the uplink operating frequency range of source 2;

[0090] First, calculate the average input power of the two signals at point B:

[0091]

[0092] Among them, the power of the output signal of source 1 at point B is P1-L1-L com (Unit: dBm), the power of the output signal of source 2 at point B is P2-L2-L com (unit: dBm), PIM2 is the third-order intermodulation value of the final coverage subsystem S under the condition of 2×43dBm (unit: dBc). Because the coverage subsystem S is generally complex in structure, with more components and connectors, and has higher requirements on construction technology, and considering the difficulty of on-site construction and the difficulty of construction workers to achieve the ideal level of construction technology, the overall third-order intermodulation index of the final coverage subsystem S is poor, and the value is generally between -90dBc and 110dBc;

[0093] If P ave >43dBm, then P ave For every 1dB increase, the third-order intermodulation suppression decreases by 2dB.

[0094] The strength of the third-order intermodulation signal generated at point B of the final coverage subsystem S, after passing through the combiner / POI and the front coverage subsystem N, reaching point A of the signal source N is:

[0095] P interfere =P ave -L com -L N +PIM2+2×(P ave -43)

[0096] If P ave <43dBm, then P ave For every 1dB below the limit, the third-order intermodulation suppression increases by 2dB:

[0097] P interfere =P ave -Lcom -L N +PIM2-2×(43-P ave )

[0098] After comprehensive consideration, the above formula can be combined into:

[0099] P interfere =P ave -L com2 -L2+PIM2+2×(P ave -43)

[0100] Assume that the maximum uplink interference level allowed by the system of signal source N is P IoT , then P should be interfere <P IoT , that is, P ave -L com2 -L2+PIM2+2×(P ave -43)<P IoT ,

[0101] For the sake of simplicity, assume that P1=P2=P=P ave =43dBm and L1=L2=L N =L, that is, the front-end coverage subsystem 1, the front-end coverage subsystem 2, and the front-end coverage subsystem N have the same insertion loss. The above statement can be simplified to:

[0102] PLL com -L com -L+PIM2-2×(L+L com )<P IoT

[0103] P-4L com +PIM2-P IoT <4L

[0104] L>(P-4L com +PIM2-P IoT ) / 4

[0105] It can be obtained that the insertion loss of the front-end coverage subsystem 1, the front-end coverage subsystem 2, and the front-end coverage subsystem N should be greater than (P-4L com +PIM2-P IoT ) / 4, similarly, the minimum insertion loss values ​​of the front coverage subsystem 1, the front coverage subsystem 2, and the front coverage subsystem N can also be calculated when the third-order intermodulation signal received at point A' of the signal source 2 is lower than the maximum background noise required by the signal source 2 system.

[0106] In an embodiment of the present invention, the information generation method can calculate the minimum insertion loss value of each front coverage subsystem by obtaining the insertion loss of the third combiner, the N output powers and N maximum uplink interference levels corresponding to the N information sources, and the third-order intermodulation index of the target coverage subsystem, thereby ensuring that the intensity of the third-order intermodulation signal generated by the target coverage subsystem when it returns to each information source meets the highest background noise requirement of the information source system, and minimizes the impact of the third-order intermodulation interference generated by the target coverage subsystem, thereby ensuring that the indoor distributed coverage system of the multi-information source system combines to meet the communication requirements of each information source.

[0107] Optionally, classifying the N information sources based on the N operating frequency ranges and the N uplink operating frequency ranges to obtain a category label of each information source includes:

[0108] Based on the N operating frequency ranges, respectively calculate L signal frequencies corresponding to third-order intermodulation signals generated by signals of any two of the N signal sources, to obtain signal frequencies of L third-order intermodulation signals, where L is a positive integer;

[0109] Based on the L signal frequencies and the N uplink operating frequency ranges, the N information sources are classified to obtain a category label of each information source.

[0110] Specifically, for example, information source 1 and information source 2 are connected to the input end of the coverage subsystem through a combiner / POI, the operating frequency of information source 1 is f1, the operating frequency of information source 2 is f2, and the frequency of the third-order intermodulation interference signal generated by the two input signals in the coverage subsystem is: f3=2×f1±f2 or f3=2×f2±f1. If the frequency f3 falls within the uplink operating frequency range of information source 3, it means that information source 1 and information source 2 generate third-order intermodulation interference to information source 3. After frequency f3 passes through the combiner / POI in the reverse direction, it returns to information source 3 and generates uplink interference to information source 3. Then, the category labels of information source 1 and information source 2 are obtained as interfering information sources, and information source 3 is obtained as an interfered information source.

[0111] In actual situations, the operating frequencies of source 1 and source 2 are in a range, that is, the operating frequency of source 1 is f1~f2, where f1 is the starting frequency and f2 is the ending frequency; the operating frequency of source 2 is f3~f4, where f3 is the starting frequency and f4 is the ending frequency. Figure 4 is a frequency diagram of two-way broadband signals and their third-order intermodulation interference signals provided by an embodiment of the present invention, such as Figure 4As shown, f1≤f2≤f3≤f4, the corresponding third-order intermodulation signals generated by the two working frequencies of source 1 and source 2 are also in two ranges, namely f5-f6 and f7-f8. In this case, third-order intermodulation signals f5-f6 may fall into the uplink working frequency range of source 3, while f7-f8 fall into the uplink working frequency range of source 2. This third-order intermodulation signal not only falls into the uplink working frequency range of source 3, but also falls into the uplink working frequency range of source 1 or source 2. This means that the third-order intermodulation signals generated by the working frequencies of source 1 and source 2 also generate uplink interference to source 1 or source 2. If uplink interference is generated to source 1 and no uplink interference is generated to source 2, the category label of source 1 is obtained, source 1 is an interfering source, source 2 is an interfering source, and source 3 is an interfered source.

[0112] In an embodiment of the present invention, the information generation can be performed by calculating L signal frequencies corresponding to third-order intermodulation signals generated by signals of any two of the N signal sources, and then comparing the L signal frequencies with the N uplink operating frequency ranges, so that the specific category labels of the N signal sources can be accurately determined and the N signal sources can be accurately classified.
