Description

Technical Field

[0001] The present invention relates to the wireless field, and in particular to a base station construction plan guidance method, device and storage medium. Background Art

[0002] Cross-slot interference occurs when two time division duplex (TDD) systems use the same or adjacent frequencies but the time slots are not synchronized, such as in the 4.9 GHz New Radio (NR) public network using the 7D3U type and the industry network using the 1D3U type, and / or the Supplementary Uplink (SUL) and the existing fourth generation mobile communication technology (4G).

[0003] For adjacent-frequency deployment scenarios, where two systems are deployed adjacent to each other within the same frequency band, if the time slots of the two TDD systems are synchronized, there will be no interference. However, if they are not synchronized, cross-time slot interference will be introduced because the RF filters are in the passband of both systems and have no suppression.

[0004] For co-adjacent frequency deployment scenarios, i.e., two systems deployed on the same adjacent frequency band, if the two TDD systems' time slots are synchronized, there will be no interference; if they are not synchronized, co-adjacent frequency cross-time slot interference will be introduced.

[0005] When cross-timeslot interference occurs between macro stations, macro stations and pico stations, pico stations and pico stations, and pico stations and macro stations, the downlink of one TDD system will interfere with the uplink of another TDD system, as well as the conventional co-frequency / adjacent frequency co-slot interference. For the former, the spatial isolation solution may be difficult to meet the requirements; for the latter, the system performance is reduced. Summary of the Invention

[0053] The present invention will be further described in detail with reference to the embodiments, and the related technologies will be described first.

[0054] Figure 1 is a schematic diagram of cross-slot interference; Figure 1 In the figure, D represents the downlink time slot, S represents the special time slot, and U represents the uplink time slot. As can be seen from the arrows in the figure, cross-link interference exists.

[0055] To address the issue of cross-link interference, it has been proposed that cross-link interference scenarios can be simulated in advance. However, due to the relatively low maturity of the 4.9GHz industry and the complexity of setting up a cross-interference test network environment (few test points, complex channel environments, and diverse engineering parameters), there are risks in providing universal technical conclusions and cross-slot construction guidance.

[0056] First, due to limitations in construction and property coordination, there are relatively few scenario sample points available for testing. Second, the channel environment is multifaceted and difficult to accurately fit, making it impossible to derive cross-deployment guidance through theoretical analysis. Finally, the actual field engineering planning and construction situations are diverse, making it impossible to provide universal technical conclusions.

[0057] Based on this, the method provided in an embodiment of the present invention determines a first test result that meets the first requirement by adjusting the isolation distance between the first node and the second node; the first requirement includes: the noise floor rise value of the second node is a first target value; the first test result includes: the first isolation distance between the first node and the second node; by adjusting the transmission power of the first node, a second test result that meets the second requirement is determined; the second requirement includes: the noise floor rise value of the second node is a second target value; the second test result includes at least one of the following: the transmission power of the first node, the service rate of the second node; based on the first test result and the second test result, the target isolation distance and / or target noise floor rise value under the target rate requirement is determined.

[0058] The present invention will be further described in detail below with reference to the embodiments.

[0059] Figure 2 A flow chart of a base station construction scheme guidance method provided by an embodiment of the present invention; Figure 2 As shown, the method includes:

[0060] Step 201: Determine a first test result that meets a first requirement by adjusting the isolation distance between a first node and a second node; the first requirement includes: a noise floor elevation value of the second node being a first target value; and the first test result includes: a first isolation distance between the first node and the second node.

[0061] Step 202: Determine a second test result that meets a second requirement by adjusting the transmit power of the first node; the second requirement includes: a noise floor rise value of the second node being a second target value; and the second test result includes at least one of the following: the transmit power of the first node and the service rate of the second node.

[0062] Step 203: Determine a target isolation distance and / or a target noise floor rise value under a target rate requirement based on the first test result and the second test result.

[0063] In some embodiments, determining the first test result that meets the first requirement by adjusting the isolation distance between the first node and the second node includes:

[0064] Determine a set of test points based on a reference isolation distance and a preset difference distance; the set of test points includes: a first test point that is separated from the first node by the reference isolation distance, and a second test point that is separated from the first test point by N preset difference distances;

[0065] When the first node operates at a first transmission power, a background noise rise value of the second node at a corresponding test point is tested to obtain a first test result.

[0066] Wherein, N is an integer.

[0067] Here, the first test result includes: at least one first target value and an isolation distance corresponding to each first target value.

[0068] The first target value is set by the tester based on their needs. For example, the first target value (i.e., the noise floor boost value) includes at least one of the following: 10dB, 3dB, and 1dB. The first target value can also be other values ​​based on needs, which are not limited here.

[0069] Specifically, the reference isolation distance is recorded as d1, and the preset difference distance is recorded as d;

[0070] Based on the reference isolation distance and the preset difference distance, a set of points to be measured is determined, including:

[0071] Determine {…, d1-2d, d1-d, d1, d1+d, d1+2d, …} as a set of points to be measured.

[0072] Here, the first node is a disturbing station and the second node is a disturbed station;

[0073] The second node may use a frequency sweeper to detect the background noise level at the point to be measured.

[0074] Specifically, to detect the relationship between interference intensity (i.e., noise floor rise) and isolation distance, in an isolated scenario, the interfering station (i.e., the first node) is turned on and its transmit power is configured, for example, to 200W.

[0075] A frequency sweeper is used to simulate the construction location of the disturbed station (i.e., as the second node) at different locations. The background noise level at each test point is calculated within a certain range (e.g., {…, d1-d, d1, d1+d, …}) within the reference isolation distance d1.

[0076] At this time, the interfering station's terminal (such as a mobile phone or other communication device) is located at the edge of the cell where the interfering station and the scanner are connected. It initiates a downlink full buffer service. The scanner simulates the interfered station and records the noise floor level {…, x1 dBm / MHz, y1 dBm / MHz, z1 dBm / MHz, …} detected by itself, as well as the actual test environment (such as frontal, side, and rear).

[0077] Here, frontal, side and back-facing refer to signal transmission between the first node and the second node at different direction angles; for example, if the base stations are facing each other head-on, the angle is 0 degrees; if the base stations are facing each other back-to-back, the angle is 180 degrees.

[0078] In some embodiments, determining a second test result that meets a second requirement by adjusting the transmit power of the first node includes:

[0079] Determine a power set to be measured based on a preset power difference and a reference transmit power; the power set to be measured includes: a first power to be measured and a second power to be measured; the first power to be measured is the reference transmit power; the second power to be measured differs from the first power to be measured by M preset power differences;

[0080] When the second node is set at a specific test point, the background noise rise value of the second node when the first node operates at the corresponding power to be tested, and the uplink rate of the terminal in the cell corresponding to the second node when the first node operates at the corresponding power to be tested are tested to obtain a second test result.

[0081] Wherein, M is an integer.

[0082] Here, the second test result includes: at least one second target value and the transmission power of the first node corresponding to each second target value.

[0083] The second target value is set by the tester based on their needs. For example, the second target value (i.e., the noise floor boost value) includes at least one of the following: 10dB, 3dB, and 1dB. The second target value can also be other values ​​based on needs, which are not limited here.

[0084] Specifically, to determine the relationship between interference intensity (i.e., noise floor rise), transmit power, and service rate (i.e., the uplink rate of the terminal under the interfered station), the transmit power of the interfering station (i.e., the first node) is gradually reduced in a certain step size (e.g., 3dB), for example, from 200W to 50W.

[0085] At the victim station (i.e., the second node), the scanner determines the noise floor level {…, x2 dBm / MHz, y2 dBm / MHz, z2 dBm / MHz, …} and records the corresponding transmit power {…, y1, y2, y3, …} of the interfering station (i.e., the first node).

[0086] The interfering station (i.e., the first node) configures the transmit power {..., y1, y2, y3, ...} and turns on the victim station (i.e., the second node), configuring the same frame structure and different frame structures. Here, by configuring the same frame structure and different frame structures, the rate loss of different frame structures relative to the same frame structure can be compared.

[0087] The terminal under the disturbed station initiates an uplink full packet service, locks the disturbed cell for traversal testing, and counts the uplink rate of the terminal under the disturbed station. The specific method can be to determine the uplink rate of the terminal under the disturbed station by recording the relationship curve between the reference signal received power (RSRP) of the synchronization signal block (SSB) and the uplink rate.

[0088] In some embodiments, the first test result includes: at least one first target value and an isolation distance corresponding to each first target value;

[0089] The second test result includes: at least one second target value, the transmit power of the first node corresponding to each second target value, and a service rate corresponding to the transmit power of each first node; the service rate is an uplink rate of the terminal in the cell corresponding to the second node;

[0090] The determining, based on the first test result and the second test result, a target isolation distance and / or a target noise floor rise value under a target rate requirement includes:

[0091] Determine a first relationship based on the first test result; the first relationship is a relationship between the noise floor rise value and the isolation distance;

[0092] Determine a second relationship based on the second test result; the second relationship includes: a relationship between a noise floor rise value (referring to the noise floor rise value of the second node) and a transmit power (referring to the transmit power of the first node), and a relationship between a service rate (referring to the uplink rate of the terminal under the second node) and a transmit power (referring to the transmit power of the first node);

[0093] Based on the first relationship and the second relationship, an isolation distance and / or a noise floor rise value under a target rate requirement is determined.

[0094] The target rate requirement includes: the required uplink rate of the terminal under the second node.

[0095] Here, based on the first and second test results, the relationship between transmit power, noise floor, isolation distance, and service rate can be determined. Based on the target service rate requirement (i.e., the required uplink rate of the terminal under the second node), the transmit power can be determined in combination with the above relationship. Based on the transmit power, the required noise floor can be determined. Finally, the required isolation distance can be determined for typical station heights, downtilt angles, and antenna attenuation configurations under conditions that allow the target rate.

[0096] In some embodiments, the method further comprises:

[0097] Determine the first node and the second node whose isolation distance satisfies a preset distance condition;

[0098] The preset distance condition is satisfied when the difference between the isolation distance and the preset reference isolation distance is less than a difference threshold.

[0099] Here, assuming a typical cross-interference test scenario, based on the typical working parameter values ​​of the existing network (including station height, downtilt angle, azimuth angle (front, side and back), antenna attenuation, etc.), the required isolation (MCL, Maximum Coupling Loss) and isolation distance d1 when the allowable total noise floor is raised to a certain value (such as 3dB) can be derived, and the determined required isolation distance d1 is used as the reference isolation distance.

[0100] The isolation is calculated based on the transmit power and the noise floor rise value at the receiving end;

[0101] The isolation distance d1 is determined based on the isolation degree and the actual geographical location; or, it can be given by the personnel who build the base station based on the geographical environment location, which is not limited here.

[0102] Through the reference isolation distance, two nodes whose isolation distance meets the preset distance conditions are determined; that is, the first node and the second node whose isolation distance is closest to d1 are selected (such as macro-to-skin, skin-to-skin, micro-to-skin and other actual station sites for testing), and one node is determined as the interfering station and the other node is the disturbed station.

[0103] The method provided by the embodiment of the present invention obtains the relationship between the interference level (i.e., the noise floor rise value of the above-mentioned disturbed station) and the isolation distance, as well as the relationship between the transmission power and the service rate of the terminal, to provide guidance on the construction plan during actual construction, reduce the complexity of construction, and improve the efficiency of traversing all sample point cross-interference test scenarios, making cross-interference construction guidance suggestions possible.

[0104] The method provided in an embodiment of the present invention can be applied to any server (or electronic device), which can obtain the test results (including but not limited to communicating with the corresponding device that detects the test results to obtain the test results), and based on the test results, give a recommended target isolation distance and noise floor rise value according to the target rate requirements.

[0105] The base station construction plan guidance method provided by the embodiment of the present invention can be applied to at least the following scenarios:

[0106] Scenario 1: Macro sites intersect, downlink interference on uplink;

[0107] Specifically, the interference of the downlink transmission of the macro base station 1 on the uplink transmission of the macro base station 2 is detected.

[0108] Macro station 1 is used as the interfering station, and macro station 2 is used as the interfered station.

[0109] Scenario 2: Macro and pico cells: The macro downlink interferes with the pico cell uplink, or vice versa.

[0110] Specifically, the interference of the downlink transmission of macro station 3 on the uplink transmission of pico station 1 is detected. At this time, macro station 3 acts as the interfering station and pico station 1 acts as the interfered station.

[0111] Or detect the interference of the downlink transmission of the pico station 1 on the uplink transmission of the macro station 3. At this time, the macro station 3 serves as the interfered station and the pico station 1 serves as the interfering station.

[0112] Scenario 3: Peer-to-peer station: Downlink interference on uplink;

[0113] Specifically, the interference of the downlink transmission of the second pico station to the uplink transmission of the third pico station is detected.

[0114] Pi station 2 is used as the disturbing station, and Pi station 3 is used as the disturbed station.

[0115] Scenario 4: Micro and pico base stations: Downlink interference on uplink;

[0116] Specifically, the interference of the downlink transmission of micro station one on the uplink transmission of pico station four is detected.

[0117] Micro station 1 is used as the disturbing station, and Pi station 4 is used as the disturbed station.

[0118] That is to say, the first node may be a macro base station, a pico base station, or a micro base station; the second node may be a macro base station or a pico base station.

[0119] The base station construction plan guidance method provided by the embodiment of the present invention can be applied to any required scenario, including but not limited to the above-mentioned scenario one, scenario two, scenario three, and scenario four.

[0120] Figure 3 A flow chart of another base station construction scheme guidance method provided by an embodiment of the present invention; Figure 3 As shown in the figure, the interfering station operates at a certain transmission power. A frequency sweeper is set up at a certain distance from the interfering station, such as {…, d1-2d, d1-d, d1, d1+d, d1+2d, …}, as the victim station to measure the noise floor level of the victim station. Here, d is 5 km. This tests the relationship between interference intensity and isolation distance.

[0121] The interfering station was configured with different transmit powers. The victim station was enabled, configured with the same and different frame structures. The terminal at the victim station initiated an uplink flood service, locked onto the interfered cell, and recorded the relationship between SSB RSRP and uplink rate. The noise floor at the victim station was also recorded {…, x'dBm / MHz, y'dBm / MHz, z'dBm / MHz, …}. This method tests the relationship between transmit power and noise floor, and also the relationship between transmit power and the terminal's uplink rate.

[0122] Figure 4 A flow chart of another base station construction scheme guidance method provided by an embodiment of the present invention; Figure 4 As shown, the method includes:

[0123] Step 401: Determine the relationship between the isolation distance and the noise floor rise value of the disturbed station (reflecting the interference intensity);

[0124] Specifically, by adjusting the isolation distance between the interfering station and the interfered station, the isolation distance between the interfering station and the interfered station is determined when the noise floor rise value of the interfered station is 10 dB, 3 dB and / or 1 dB respectively.

[0125] Step 402: Determine the relationship between the noise floor rise value of the interfered station and the uplink rate;

[0126] Specifically, the noise floor level of the disturbed station can be recorded as {…, x'dBm / MHz, y'dBm / MHz, z'dBm / MHz, …}. Here, by adjusting the transmit power of the disturbing station, the transmit power of the disturbing station is determined to make the noise floor increase value of the disturbed station 10dB, 3dB and / or 1dB respectively (the noise floor increase value is determined based on the noise floor level); and the uplink rate of the disturbed cell is tested respectively.

[0127] Step 403: Determine the relationship between the service rate and the isolation distance;

[0128] Specifically, according to the test results of step 401 and step 402, the relationship between the service rate and the isolation distance is obtained;

[0129] The relationship between the service rate and the isolation distance is used to provide the isolation distance and the noise floor rise value under the allowable target rate requirement.

[0130] Here, the target rate requirement may include: a target rate loss of the interfered station.

[0131] The target rate loss refers to the relative value between interference and no interference; interference refers to the uplink rate of the terminal at the interfered station when the terminal at the interfering station performs full packet filling service, and no interference refers to the uplink rate of the terminal at the interfered station when the terminal at the interfering station does not perform packet filling service;

[0132] That is, the target rate loss refers to the uplink rate loss that is permissible to the terminal under the interfered station; or, in other words, the uplink rate that the interfered station terminal requires to achieve.

[0133] Specifically, according to the test results of steps 401 and 402 above, when applied, according to the target rate requirements (i.e., the corresponding uplink rate requirements of the terminal under the interfered station), the required noise floor level can be inferred, and then the required isolation distance can be found, that is, the isolation distance required under the typical station height, downtilt angle, and antenna attenuation configuration under the allowable target rate conditions is given respectively.

[0134] The application of the above method can reduce the complexity of construction, improve the efficiency of traversing all sample points in the cross-interference test scenario, and make cross-interference construction guidance suggestions possible.
