[0026] To make the objectives, technical solutions, and advantages of this application more apparent, exemplary embodiments according to this application will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of this application, and not all embodiments of this application. It should be understood that this application is not limited to the exemplary embodiments described herein.
[0027] Referring to Figure 1, the base station system 100 may include a base station 101, a repeater 102, a base station network management system 103, and a repeater network management system 104. The base station network management system 103 is communicatively connected to the repeater network management system 104, the base station network management system 103 is communicatively connected to the base station 101, and the repeater network management system 104 is communicatively connected to the repeater 102.
[0028] In this embodiment of the application, the gain adjustment method performed by the repeater network management is used as an example for illustration.
[0029] Referring to Figure 2, a gain adjustment method includes: S201, determining a first target repeater belonging to a first target base station, wherein the first target base station is a base station whose terminal call drop rate is greater than a first preset threshold.
[0030] During this step, the repeater network management system can identify the first target base station whose terminal call drop rate is greater than a first preset threshold. Based on the affiliation between the repeater and the first target base station, the system determines the first target repeater belonging to the first target base station. The first preset threshold can be set according to requirements.
[0031] The attribution determination process is as follows: The base station network management system obtains the base station number (Cell Identity, cellID) and the serving cell physical identifier (Physical Cell Identifier, PCI) and sends them to the repeater network management system. The repeater network management system compares the received base station number (cellID) and serving cell physical identifier (PCI) with the information registered by the repeaters in the database to obtain the connection relationship between the base station and the repeater. Based on this correspondence, the first target repeater belonging to the first target base station is determined.
[0032] Referring to Figure 1, the repeater network management system may include a repeater information transceiver module, a status identification module, and a gain adjustment decision module; the base station network management system may include a base station information transceiver module and a base station status identification module; the base station may include a base station monitoring module; and the repeater may include a repeater monitoring module and a low noise amplifier and attenuator (ATT) module.
[0033] The repeater information transceiver module is responsible for periodically obtaining the base station number (cellID) and serving cell physical identifier (PCI) from the base station network management system; and obtaining the repeater's downlink reference signal receiving power (RSRP), rated output power, and uplink output power.
[0034] The status identification module is responsible for matching cellID and PCI information with the repeater database to obtain the connection relationship between the base station and the repeater. It uses the repeater's uplink output power to identify whether the repeater is idle.
[0035] The gain adjustment decision module is responsible for calculating the required gain value for each repeater under the current conditions based on the indicators of each repeater and base station, according to set formulas and thresholds. It also controls the low-noise amplifier (ATT) module to adjust the repeater gain.
[0036] The base station information transceiver module is responsible for collecting the base station's cellID and PCI, as well as base station noise indicators, and sending them to the repeater network management system periodically.
[0037] The base station status identification module is responsible for receiving base station noise and terminal call drop rate. When the base station noise exceeds the preset threshold or the call drop rate exceeds the preset threshold, the gain adjustment process is triggered.
[0038] The base station monitoring module is responsible for monitoring uplink injected noise and terminal call drop rate of the base station.
[0039] The repeater monitoring module is responsible for acquiring the repeater's operating parameters and performance indicators. Performance indicators include the RSRP level of the downlink amplified signal at the signal receiving port and the uplink output signal value; the low-noise amplifier (ATT) module is responsible for adjusting the repeater's uplink and downlink gains.
[0040] This step can be triggered by the base station network management system. For example, the repeater network management system executes this step upon receiving a gain adjustment trigger command from the base station network management system. The base station network management system can set a preset time interval, such as half an hour, to detect base station noise and terminal call drop rate at this preset time interval. When the terminal call drop rate exceeds a first preset threshold or the base station noise exceeds a second preset threshold, a corresponding gain adjustment trigger command is generated to trigger the repeater network management system to execute the relevant steps. The first and second preset thresholds can be set according to requirements. Alternatively, it can be triggered by other methods.
[0041] S202, determine the first target gain of the first target repeater, and control the first target repeater to perform gain adjustment based on the first target gain, wherein the first target gain is determined based on the rated output power of the first target repeater and the downlink reference signal received power.
[0042] In this step, the first target gain is used to match the output power of the first target repeater to its rated output power.
[0043] In this step, when controlling the first target repeater to perform gain adjustment based on the first target gain, the first target repeater can be sent to the first target repeater so that the first target repeater can perform gain adjustment according to the first target gain and the corresponding downlink target gain. Alternatively, the first target repeater can be sent to the first target repeater so that the first target repeater can directly perform adjustment. Or, the first target repeater can be controlled to perform gain adjustment based on the first target gain through other means.
[0044] In this step, the gain adjustment decision module included in the repeater network management can control the first target repeater to perform gain adjustment based on the first target gain. The ATT module included in the repeater performs gain adjustment based on the first target gain to increase the uplink and downlink gain of the corresponding repeater to the first target gain. By matching the repeater output with the rated output capacity, the high call drop rate of the terminals connected to the repeater under these first target base stations can be optimized.
[0045] S203, Identify the second target repeater that is in an idle state.
[0046] During this step, the repeater network management system can determine whether a repeater is in an idle state based on its uplink output power. The repeater in an idle state will be designated as the second target repeater, which is a repeater whose gain can be reduced. An idle state can be defined as when the uplink output power is less than a preset idle power threshold, which can be set according to requirements.
[0047] In the specific implementation process, the second target repeater can be marked as a repeater with "reduced gain" so that subsequent steps can determine the target gain of the repeater.
[0048] This step can be triggered by the base station network management system. For example, the repeater network management system executes this step when it receives a gain adjustment trigger command from the base station network management system. The base station network management system can set a preset time interval, such as half an hour, to detect base station noise and terminal call drop rate at the preset time interval. When the terminal call drop rate is greater than a first preset threshold or the base station noise is greater than a second preset threshold, the system generates a corresponding gain adjustment trigger command to trigger the repeater network management system to execute the relevant steps. Alternatively, it can be triggered in other ways.
[0049] S204, determine the second target gain of the second target repeater, and control the second target repeater to perform gain adjustment based on the second target gain, wherein the second target gain is determined based on the target uplink noise level.
[0050] During this step, the repeater network management system can determine the second target gain of the second target repeater. This second target gain is determined based on the target uplink noise level of the second target repeater. The aim is to reduce the gain of the second target repeater when gain adjustment based on the second target gain is performed, thereby reducing the noise injection level. The target uplink noise level is the desired noise level value, which can be preset or determined according to relevant methods.
[0051] The gain adjustment method of this application embodiment, based on the gain adjustment method, apparatus, electronic device, storage medium, and program product of this application embodiment, determines a first target repeater by identifying repeaters belonging to base stations with terminal call drop rates greater than a first preset threshold, and determines a first target gain based on the rated output power and downlink reference signal received power of the first target repeater. The gain of the first target repeater is then adjusted to match its actual received signal strength and rated output capability, thereby avoiding insufficient coverage or increased terminal call drop rates due to unreasonable gain settings. Simultaneously, by identifying idle repeaters as second target repeaters, and determining a second target gain based on the target uplink noise level, the gain of the second target repeaters is adjusted to suppress uplink noise injected into the base station by idle repeaters. This ensures terminal coverage while effectively controlling base station noise, thereby improving the overall performance of the base station system.
[0052] In one embodiment, referring to FIG3, determining the first target gain of the first target repeater includes: S301, obtaining the rated output power and downlink reference signal received power of the first target repeater.
[0053] In this step, the repeater network management system obtains the rated output power of the first target repeater and the downlink reference signal received power actually received by the first target repeater.
[0054] S302 determines the downlink full-load input power based on the downlink reference signal received power.
[0055] In this step, the total full-load power from the source base station to the downlink input port of the repeater can be calculated using the following formula:
[0056] in, This represents the total power at full load for the downlink. This refers to the downlink reference signal received power. The coupling degree of the coupler in the repeater system. This represents the number of subcarriers. and In the repeater system, all values are known and fixed.
[0057] S303, determine the first target gain based on the difference between the rated output power of the first target repeater and the downlink full-load input power.
[0058] In this step, the first target gain can be calculated using the following formula:
[0059] in, The gain for the primary target is considered as the reasonable gain for the primary target repeater. Rated output power, The downlink full-load input power is the total full-load power from the base station to the downlink input port of the repeater.
[0060] In this embodiment, the downlink full-load input power is determined by the downlink reference signal received power, and the first target gain is determined based on the downlink full-load input power to obtain a first target gain that matches the rated output capability of the first target repeater. When adjusting the gain based on the first target gain, it can avoid the first target repeater's output power from exceeding its rated output capability and entering an overload state due to unreasonable gain settings, and make the gain adjustment result consistent with the output capability constraint of the first target repeater.
[0061] In one embodiment, referring to FIG4, determining the second target gain of the second target repeater includes: S401, acquiring the target uplink noise level.
[0062] In this step, the target uplink noise level is the target uplink noise level of the repeater, which serves as the optimization target. When there is only one repeater belonging to the base station, the target uplink noise level can be a specific preset value. When there are two or more repeaters belonging to the base station, the method for determining the target uplink noise level will be explained in subsequent embodiments. The specific number of repeaters belonging to the base station can be determined based on the connection relationship between the repeaters and the base station.
[0063] S402, obtain the uplink equivalent noise reference level.
[0064] In this step, the uplink equivalent noise reference level is determined by both the repeater's own noise characteristics and uplink conditions. This level can be determined based on the repeater's thermal noise, uplink noise figure, and uplink loss. Specifically, it can be calculated using the following formula:
[0065] in, Thermal noise from repeaters This represents the uplink noise figure of the repeater. This refers to the uplink loss of the repeater.
[0066] S403 determines the second target gain of the second target repeater based on the uplink equivalent noise reference level and the target uplink noise level.
[0067] The second target gain of the second target repeater can be calculated using the following formula:
[0068] in, For the second objective gain, The target uplink noise level, Thermal noise from repeaters This represents the uplink noise figure of the repeater. This refers to the uplink loss of the repeater.
[0069] It is determined based on the following relational function:
[0070] in, This represents the uplink noise level of the repeater. Thermal noise from repeaters For the benefit of the repeater uplink, This represents the uplink noise figure of the repeater. This refers to the uplink loss of the repeater.
[0071] The uplink noise figure of the repeater can be set according to requirements, for example, it can be set to 5dB. The uplink loss is equal to the difference between the output power of the base station to which the repeater belongs and the input power of the repeater.
[0072] In this embodiment of the application, the target uplink noise level and the uplink equivalent noise reference level are obtained, and the second target gain is determined based on the uplink equivalent noise reference level and the target uplink noise level, so that the gain adjustment of the second target repeater meets the constraint requirements of the target uplink noise level.
[0073] In one embodiment, referring to FIG5, obtaining the target uplink noise level includes: S501, determining the second target base station to which the second target repeater belongs, and all repeaters belonging to the second target base station.
[0074] In this step, the second target base station to which a certain second target repeater belongs is determined, as well as all repeaters belonging to the second target base station. Based on whether the number of all repeaters belonging to the second target base station is greater than or equal to 2 or less than 2, the method for obtaining the target uplink noise level is determined.
[0075] S502, when the number of repeaters belonging to the second target base station is equal to 1, the target uplink noise level is determined based on the preset uplink noise level.
[0076] In this step, the number of repeaters belonging to the second target base station refers to the number of repeaters belonging to the same second target base station. When the number of repeaters belonging to the second target base station is equal to 1, it means that there is only one corresponding second target repeater belonging to the second target base station, and the preset uplink noise level of the second target repeater can be used as the target uplink noise level.
[0077] S503, when the number of repeaters belonging to the second target base station is greater than or equal to 2, the target uplink noise level is determined based on the number of second target repeaters belonging to the second target base station, the current actual uplink noise level of other repeaters belonging to the second target base station, and the preset total uplink noise level of the second target base station.
[0078] In the above manner, when the number of repeaters belonging to the same second target base station is greater than or equal to 2, the corresponding target uplink noise level can be determined for each second target repeater under the preset total uplink noise level constraint of the second target base station, thereby providing a basis for the subsequent determination of the second target gain.
[0079] For example, it can be calculated using the following formula:
[0080] in, The target uplink noise level; is the total uplink noise level of the base station, in dBm; represents the superimposed uplink noise level of all repeaters preset under a base station; n is the number of repeaters directly connected to the base station in a star configuration; a series link where the base station is connected to a repeater and then cascaded with repeaters is counted as 1; when calculating noise, only the uplink noise of the first-level repeater directly connected to the base station is considered. The number of second target repeaters to be optimized. This is determined based on the number of second target repeaters belonging to the second target base station.
[0081] The derivation and principle of the above formula are as follows:
[0082]
[0083]
[0084]
[0085] in, This represents the total uplink noise level of the base station. , ... These represent the ideal uplink noise levels for the 1st to nth repeaters, respectively. is the target uplink noise level; it can be determined based on the ideal uplink noise level of the adjustable repeater; m is the number of second target repeaters to be optimized; , ... These represent the existing uplink noise levels of the 1st to nth repeaters, respectively. For the first Uplink noise level of a repeater; Thermal noise from repeaters; For the first The uplink benefit of a repeater; For the first Uplink noise figure of a repeater; For the first Uplink loss of a repeater station.
[0086] Set the uplink gain G of the repeater. min This is the minimum uplink gain value required to meet the minimum sensitivity requirements of a base station. minIt is the minimum gain threshold that ensures the base station can demodulate the uplink signal of the repeater: if the uplink gain of the repeater is lower than Gmin, the signal power received by the base station will be lower than its own receiving sensitivity, resulting in the signal being unable to be demodulated, causing the terminal to drop calls or be unable to access the network.
[0087] Uplink gain G of repeater station min Determined according to the following formula:
[0088] in, For base station receiving sensitivity, This is the minimum signal power of the terminal. This refers to uplink loss.
[0089] Base station receiver sensitivity is a hardware parameter of the base station, and it has fixed values for different standards / frequency bands. For example, the receiver sensitivity of an LTE base station is typically [value missing]. 120 125dBm; 5G NR base station is approximately 123 128dBm.
[0090] Minimum signal power of the terminal: This refers to the signal requirements of the terminal at the coverage edge of the repeater, and is determined by the network coverage standard. For example, the RSRP of indoor coverage edge terminals typically requires ≥ 115 dBm; outdoor edge ≥ 110dBm.
[0091] Uplink loss is the transmission loss between the repeater and the base station. It includes feeder loss, coupler / power divider loss, spatial transmission loss, etc., and the total is generally between 5 and 15 dB.
[0092] Therefore, the uplink gain Gmin of indoor repeaters is typically 5~10dB, while that of outdoor repeaters is 10~15dB. In one example, using... The value is used as the uplink gain Gmin of the repeater.
[0093] If the calculated target uplink noise level is less than the repeater uplink gain Gmin, then the target uplink noise level is set to the repeater uplink gain Gmin.
[0094] For example, the final uplink adjustment gain value of each adjustable repeater is calculated according to the following formula. And adjust the uplink gain of the repeater.
[0095]
[0096] The uplink adjustment gain value of each adjustable repeater is obtained through the above calculations, and the uplink gain of the repeater is adjusted based on this uplink adjustment gain value. Then, the downlink gain of the repeater is adjusted according to the set uplink-to-downlink threshold difference. Typically, the uplink-to-downlink gain difference of the repeater... The gain can be set to 5-6dB. Repeater gain adjustment is performed through the low-noise amplifier (ATT) module, with an adjustable range generally greater than 30dB. Finally, the repeater network management system uniformly sends signals to adjust the gain of each repeater, reducing the gain of those with lower loads, thereby reducing the noise pressure on the entire base station system.
[0097] In one embodiment, the attribution relationship between a base station and a repeater is determined based on the base station number and the serving cell physical identifier. Specifically, the attribution relationship between the base station and the repeater is obtained by considering the correspondence between the cell identifier and serving cell physical identifier registered in the repeater network management database and the repeater, as well as the correspondence between the base station and the repeaters in its downstream network.
