Abstract
Description
Technical Field
[0001] The present application relates to the field of wireless communication network technology, and in particular to a method and apparatus for optimizing wireless network equipment coverage. Background Art
[0002] When newly deployed network equipment, or when the geographical conditions near the deployment site have significantly changed, or when there are significant changes in service distribution, network equipment coverage needs to be optimized. Parameters such as the transmit power, carrier frequency, antenna array size and configuration, and array tilt of network equipment reflect its coverage performance. However, in real-world network scenarios, due to the complexity of wireless transmission environments, base stations with the same parameters can have different coverage performance in different deployment locations. To optimize network coverage, eliminate coverage holes, and reduce interference between network devices, after network deployment, network equipment parameters such as transmit power, antenna tilt, and array orientation can be automatically or manually adjusted to eliminate coverage issues and optimize coverage.
[0003] Adjusting transmit power affects the entire coverage area of a network device. Increasing transmit power can eliminate coverage holes, but it can also cause severe interference with adjacent cells. Reducing transmit power can reduce interference in overlapping areas, but it can also reduce coverage and create coverage holes. Therefore, optimizing coverage by adjusting transmit power doesn't achieve precise optimization within a coverage area; it only achieves balance across the entire coverage area.
[0004] Antenna tilt adjustment, as another means of coverage optimization, usually also has the following problems: the antenna tilt adjustment range is limited to a certain extent. It is usually based on the array normal being parallel to the ground, and the adjustment range does not exceed 10 degrees. Otherwise, lobe deformation is likely to occur, resulting in uncontrollable coverage changes; the coverage area affected by antenna tilt adjustment is large, and it is difficult to balance the coverage impact with multiple adjacent network devices; antenna tilt adjustment is also affected by other factors such as atmospheric ducting, and there are more restrictions in some areas.
[0005] The aforementioned antenna tilt adjustment primarily affects vertical coverage of network devices, while array orientation adjustment primarily affects horizontal coverage. However, similar to antenna tilt adjustment, array orientation adjustment also affects a larger coverage area, making it difficult to balance coverage with multiple adjacent network devices. Summary of the Invention
[0006] In view of this, the present application proposes a wireless network equipment coverage optimization method and apparatus, equipment, and storage medium, which adopts a beam measurement-based coverage optimization method to achieve independent and precise coverage optimization of different coverage areas, reducing the impact on user experience.
[0007] In a first aspect, the present application provides a method for optimizing wireless network device coverage, comprising:
[0008] Acquire at least one beam of a first network device in an area to be optimized for coverage, and configure a measurement reference signal for the beam;
[0009] Sending the measurement reference signal to each terminal accessing the first network device through the beam, and receiving measurement data reported by the terminal;
[0010] determining, based on the measurement data of each beam received by the first network device, at least one beam that meets a set condition as a coverage edge beam of the first network device;
[0011] When the total throughput of the terminal accessing the first network device through the coverage edge beam is greater than a set threshold, the coverage edge beam is selected to the optimized beam set of the first network device.
[0012] From the above, for the first network device in the coverage optimization area, the present application obtains one or more beams under the first network device and configures measurement reference information for each beam respectively. When the terminal accesses the first network device through a certain beam, the first network device sends a measurement reference signal corresponding to the certain beam to the terminal, so that the terminal measures the certain beam according to the received measurement reference signal and reports the measurement data to the first network device. The first network device determines one or more beams that meet the set conditions as the coverage edge beams of the first network device based on the measurement data of each beam received. Then, based on the total throughput of the terminal accessing the first network device through the coverage edge beam, when it exceeds the set threshold, it can be determined that the coverage edge beam meets the optimization condition and can be selected into the optimized beam set of the first network device. The optimized beam set finally determined by this method can realize the coverage optimization adjustment of the first network device to the coverage optimization area to be covered, so that the beams in the coverage area can provide users with a higher network experience. By using the beam measurement method to select an optimized beam set for the network device, the coverage area of the network device can be adjusted and optimized. At the same time, the adjustment and optimization of the coverage area of the present application can be realized when the terminal accesses the network device, and independent optimization of different coverage areas can be achieved based on the measurement data. There is no need to adjust the entire coverage area of the network device, which reduces the impact on user experience.
[0013] Optionally, the setting condition includes at least one of the following:
[0014] The number of terminals reporting that the received signal-to-noise ratio corresponding to the beam is lower than the set threshold exceeds a set ratio of the total number of reporting terminals;
[0015] The number of terminals reporting that the received signal strength corresponding to the beam is lower than the set threshold exceeds the set ratio of the total number of reporting terminals;
[0016] The number of terminals reporting that the throughput corresponding to the beam is lower than the set threshold exceeds a set proportion of the total number of reporting terminals.
[0017] From the above, in this application, selecting a coverage edge beam for the coverage edge of the first network device is actually selecting some beams that are lower than the communication quality critical value as the coverage edge beam of the first network device, and then determining whether the coverage edge beam can eventually enter the optimized beam set of the first network device based on the total throughput of the terminal accessing the first network device through the determined coverage edge beam. For example, for a certain beam, multiple terminals report measurement data corresponding to the beam. When the number of terminals with a received signal-to-noise ratio lower than a set threshold exceeds a set proportion of the total number of reporting terminals, or the number of terminals with a received signal strength lower than a set threshold exceeds a set proportion of the total number of reporting terminals, or the number of terminals with a throughput lower than a set threshold exceeds a set proportion of the total number of reporting terminals, it can be said that the communication quality of multiple terminals when accessing the first network device through the beam has reached the minimum critical value, and the beam can be determined as the coverage edge beam of the first network device.
[0018] Optionally, the method further includes obtaining, through the first network device, measurement data reported by a specific terminal when accessing an adjacent second network device, where the specific terminal is a terminal that has reported measurement data corresponding to the beam to the first network device and has reported measurement data to the second network device; the setting condition includes:
[0019] The number of specific terminals reporting measurement data corresponding to the beam exceeds a set ratio of the total number of reporting terminals.
[0020] From the above, when there is an adjacent second network device around the first network device, and the terminal accessing the first network device has also accessed the second network device, and performed beam measurement on the beam under the second network device and reported the measurement data, the measurement data reported by the terminal when accessing the second network device can be obtained through the first network device. According to the measurement data of each beam of the first network device and the measurement data of the second network device, the number of specific terminals that simultaneously report the measurement data corresponding to the beam to the first network device and the measurement data to the second network device can be determined. When the number of specific terminals exceeds the set ratio of the total number of terminals that report the measurement data corresponding to the beam to the first network device, the beam can be determined as the coverage edge beam of the first network device.
[0021] Optionally, when the total throughput of the terminal accessing the first network device through the coverage edge beam is greater than a set threshold, selecting the coverage edge beam to the optimized beam set of the first network device includes:
[0022] When the total throughput of the specific terminal when accessing the first network device through the coverage edge beam is greater than the total throughput of the specific terminal when accessing the second network device, the coverage edge beam is selected to the optimized beam set of the first network device.
[0023] From the above, if the total throughput of all specific terminals accessing the first network device through the coverage edge beam is greater than the total throughput of all specific terminals accessing the second network device, then the communication quality between the coverage edge beam and each specific terminal is better than the communication quality between the beam of the second network device and each specific terminal, and the coverage edge beam can be selected into the optimized beam set of the first network device. If the total throughput of all specific terminals accessing the first network device through the beam is less than the total throughput of all specific terminals accessing the second network device, then the communication quality between the beam and each specific terminal is worse than the communication quality between the beam of the second network device and each specific terminal, and it is considered that the coverage edge beam is not suitable for selection into the optimized beam set of the first network device.
[0024] Optionally, the measurement reference signal includes at least one of the following:
[0025] Synchronization reference signal, channel state measurement reference signal, demodulation reference signal.
[0026] From the above, the configured synchronization reference signal, channel state measurement reference signal, and demodulation reference signal can respectively realize the measurement of the received signal power, received signal quality, transmission channel and received signal-to-noise ratio, so as to obtain the specific situation of the terminal using the beam for communication.
[0027] Optionally, the measurement data reported by the terminal is measurement data obtained by the terminal measuring one or more beams with optimal transmission channel conditions, highest received signal-to-noise ratio, best received signal quality, or strongest received signal power;
[0028] The measurement data includes one or more of received signal power data, received signal quality data, received signal signal-to-noise ratio data, and transmission channel estimation data.
[0029] From the above, when the terminal accesses the first network device through one or more beams, it will measure each beam separately. The terminal will report the measurement data of the beam with the best transmission channel conditions, the highest received signal-to-noise ratio, the best received signal quality or the strongest received signal power to the first network device to reduce the amount of reported data.
[0030] Optionally, the determination condition for the optimal transmission channel condition includes at least one of the following:
[0031] The beam has the lowest transmission channel coupling loss for the terminal, the largest transmission channel capacity, the lowest transmission channel path loss, and the lowest transmission channel receiving interference power.
[0032] Optionally, the transmission channel estimation data includes at least one of the following:
[0033] Channel matrix data obtained by channel estimation based on the beam measurement reference signal, channel correlation matrix data calculated based on the channel matrix data, channel matrix or channel correlation matrix eigenvalue data calculated based on the channel matrix data, channel matrix or channel correlation matrix eigenvector data calculated based on the channel matrix data, and precoding matrix data calculated based on the channel matrix data.
[0034] Optionally, the receiving measurement data reported by each terminal further includes completing the measurement of the beam when the received measurement data satisfies at least one of the following:
[0035] The number of terminals reporting measurement data corresponding to the beam exceeds a set number and / or a set ratio;
[0036] The number of times the measurement data corresponding to the beam is reported exceeds a set number and / or a set ratio;
[0037] The duration of receiving the measurement data corresponding to the beam exceeds the set duration.
[0038] From the above, the terminal measures the connected beam according to the measurement reference signal and reports the measurement data. When one or more of the above conditions are met, the measurement of the beam can be completed, so that the next beam to be measured of the first network device can be measured.
[0039] In a second aspect, the present application provides a wireless network device coverage optimization device, comprising:
[0040] a configuration module, configured to obtain at least one beam of a first network device in an area to be optimized for coverage, and configure a measurement reference signal for the beam;
[0041] a transceiver module, configured to send the measurement reference signal to each terminal accessing the first network device through the beam, and receive measurement data reported by the terminal;
[0042] a determination module, configured to determine, based on the measurement data of each beam received by the first network device, at least one beam that meets a set condition as a coverage edge beam of the first network device;
[0043] The selection module is configured to select the coverage edge beam to the optimized beam set of the first network device when the total throughput of the terminal accessing the first network device through the coverage edge beam is greater than a set threshold.
[0044] In a third aspect, the present application provides a computing device, comprising:

[0053] It should be understood that the sizes and shapes of the blocks in the above structural diagrams are for reference only and should not constitute an exclusive interpretation of the embodiments of this application. The relative positions and inclusion relationships between the blocks presented in the structural diagrams are only schematic representations of the structural relationships between the blocks, and do not limit the physical connection methods of the embodiments of this application. DETAILED DESCRIPTION
[0054] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.
[0055] An embodiment of the present application provides a coverage optimization method and apparatus for a wireless network device. The method measures multiple beams of a network device by adopting a beam measurement method, determines which beams are coverage edge beams of the network device based on the measurement data obtained, and then determines whether the coverage edge beam can enter the optimized beam set of the network device based on the total throughput of the terminal accessing the network device through the coverage edge beam, thereby adjusting the coverage area of the network device. The optimization method provided in this embodiment can realize independent and fine coverage optimization of different coverage areas of the network device, reducing the impact on user experience.
[0056] The network device in this embodiment may specifically be one or more of a network node, a base station, a base station management module or system, and a network management module or system under the network architecture.
[0057] Refer to Figure 1 As shown, the coverage optimization method of the wireless network device provided in the embodiment of the present application includes the steps of:
[0058] S10: Acquire at least one beam of a first network device in the area to be optimized for coverage, and configure a measurement reference signal for the beam;
[0059] In this embodiment, the coverage optimization area may refer to a certain geographical area within which the coverage of the wireless network needs to be optimized, such as the geographical location of a newly deployed network device and the area covered by nearby network devices, or the geographical location of one or more coverage hole areas and the area covered by nearby network devices, or an area with severe network interference and the area covered by nearby network devices.
[0060] By obtaining one or more beams in the first network device in the coverage optimization area, and configuring a measurement reference signal for each beam, the terminal accessing the first network device through the beam can perform beam measurement. For example, if the first network device is a newly deployed first network device, some or all beams supported by the first network device can be obtained, and a measurement reference signal can be configured for each beam to perform beam measurement on each beam, thereby adjusting and optimizing the entire coverage area of the first network device. If the first network device is an old device, some beams in its coverage hole area or some beams in an area with severe network interference can be selected to perform beam measurement, and targeted adjustments and optimization can be performed on the coverage hole area or the network interference area.
[0061] In one embodiment, a beam set can be constructed, one or more acquired beams from the first network device can be selected into the beam set, and a measurement reference signal can be configured for each selected beam. The configured beam measurement reference signal can include one or more of a synchronization reference signal, a channel state measurement reference signal, and a demodulation reference signal. Subsequent steps measure each beam in the beam set, and selection is made based on the measurement data, ultimately determining an optimized beam set for the first network device. The first network device can optimize coverage of the optimized area to be covered using the beams in this optimized beam set.
[0062] S20: Sending the measurement reference signal to each terminal accessing the first network device through the beam, and receiving measurement data reported by the terminal;
[0063] In this embodiment, when one or more terminals located in the optimized area to be covered access the first network device through any beam in the above-mentioned beam set, the beam will send its configured measurement reference signal to the one or more terminals, and receive the measurement data reported by the terminal through the first network device. It should be noted that when the same terminal accesses the first network device, it may receive measurement reference signals sent by multiple beams, so that the first network device can select a suitable beam for the terminal for uplink and downlink transmission of the terminal. Therefore, when reporting measurement data, the terminal can report the measurement data obtained by measuring one or more beams with the best transmission channel conditions, the highest received signal-to-noise ratio, the best received signal quality, or the strongest received signal power to the first network device, while the measurement data of some beams with poor transmission channel conditions, low received signal-to-noise ratio, poor received signal quality, or weak received signal power do not need to be reported to the first network device, thereby reducing the amount of reported data.
[0064] The above-mentioned determination conditions for the optimal transmission channel conditions may specifically include: the transmission channel coupling loss of the beam to the terminal is the lowest, the transmission channel capacity is the largest, the transmission channel path loss is the lowest, and the transmission channel receiving interference power is the lowest.
[0065] In one embodiment, the measurement data reported by the terminal may specifically include: one or more of received signal power data, received signal quality data, received signal signal-to-noise ratio data, and transmission channel estimation data, or may also include indication information representing received signal power data, received signal quality data, received signal signal-to-noise ratio data, and transmission channel estimation data.
[0066] The above-mentioned received signal power data may be measurement data of the reference signal received power of the measurement reference signal by the terminal; the above-mentioned received signal instruction data may be measurement data of the reference signal reception quality of the measurement reference signal by the terminal; and the above-mentioned received signal-to-noise ratio data may be received signal-to-noise ratio data obtained by the terminal using the measurement reference signal to estimate the signal-to-noise ratio.
[0067] The above-mentioned transmission channel estimation data may include: channel matrix data obtained by channel estimation based on the beam measurement reference signal, channel correlation matrix data calculated based on the channel matrix data, channel matrix or channel correlation matrix eigenvalue data calculated based on the channel matrix data, channel matrix or channel correlation matrix eigenvector data calculated based on the channel matrix data, and precoding matrix data calculated based on the channel matrix data.
[0068] The above-mentioned indication information representing the received signal power data, received signal quality data, received signal signal-to-noise ratio data, and transmission channel estimation data may include any indication information that can be mapped to a specific numerical value of the above-mentioned data, such as a channel quality indication (Channel Quality Indication: CQI) indicating the received signal-to-noise ratio, a precoding matrix indication (Precoding Matrix Indication: PMI) and / or a rank indication (Rank Indication: RI) indicating the channel estimation result.
[0069] In this embodiment, when the first network device determines that the measurement of one beam is complete, it measures the other beams in the beam set and may also continue to add other beams for which measurement has not been completed to the beam set. The first network device may determine that the measurement of the beam is complete when the measurement data reported by the terminal and received by the first network device meets at least one of the following conditions:
[0070] The number of terminals reporting measurement data corresponding to the beam exceeds a set number and / or a set ratio;
[0071] The number of times the measurement data corresponding to the beam is reported exceeds the set number and / or the set ratio;
[0072] The duration for the first network device to receive the measurement data corresponding to the beam exceeds a set duration.
[0073] Through the above conditions, each beam in the beam set of the first network device can be measured, and measurement data corresponding to each beam reported by the terminal can be received.
[0074] S30: Determine, based on the measurement data of each beam received by the first network device, at least one beam that meets a set condition as a coverage edge beam of the first network device;
[0075] In this embodiment, based on the measurement data corresponding to each beam reported by the terminal and received by the first network device, one or more beams that meet the set conditions can be determined as the coverage edge beams of the first network device, so as to facilitate further optimization selection of the coverage edge beams. The set conditions may include:
[0076] The number of terminals reporting that the received signal-to-noise ratio corresponding to the beam is lower than a set threshold exceeds a set proportion of the total number of reporting terminals; for example, the set threshold of the signal-to-noise ratio may be 0 dBm, and the set proportion may be 20%;
[0077] The number of terminals reporting received signal strength corresponding to the beam below a set threshold exceeds a set ratio of the total number of reporting terminals. For example, the set threshold of the received signal strength may be -100 dBm, and the set ratio may be 30%.
[0078] The number of terminals reporting a throughput corresponding to the beam that is lower than a set threshold exceeds a set ratio of the total number of reporting terminals. For example, the set threshold of the throughput may be 100 kbps.
[0079] Through the above-mentioned one or more setting conditions, the beam that meets the one or more setting conditions can be determined as the coverage edge beam of the first network device, so as to facilitate further selection of the coverage edge beam in subsequent steps, thereby determining whether to select the coverage edge beam into the optimized beam set of the first network device.
[0080] In some embodiments, when there are other adjacent network devices near the first network device, such as a second network device, assuming that some terminals accessing the first network device have also accessed the second network device and performed beam measurement on the beam under the second network device and reported measurement data, for the convenience of the following description, the terminals that simultaneously report the measurement data corresponding to the beam to the first network device and report the measurement data to the second network device can be defined as specific terminals. At this time, the first network device also needs to obtain the measurement data reported by the above-mentioned specific terminal of the second network device, and determine the beam that meets the set conditions as the coverage edge beam of the first network device based on the measurement data of the first network device and the measurement data of the second network device. Specifically, the first network device sends a message requesting measurement data to its adjacent second network device via a backhaul link. The message may include identity identification information of the specific terminal that has accessed the first network device and reported measurement data of one or more beams in the first network device, such as terminal RNTI (Radio Network Temporary Identity) information, and may also include indication information of the measurement data of the second network device required by the first network device.
[0081] The measurement data of the second network device may include: measurement data of the beam in the second network device reported by the specific terminal indicated by the above-mentioned identity identification information; throughput statistics during the period when the specific terminal indicated by the above-mentioned identity identification information accesses the second network device; transmission channel statistics during the period when the specific terminal indicated by the above-mentioned identity identification information accesses the second network device, such as channel fading statistics, channel correlation matrix data, channel matrix rank indication information, etc.; channel state data during the period when the specific terminal indicated by the above-mentioned identity identification information accesses the second network device, such as signal-to-noise ratio statistics, channel state indication (CSI) reporting statistics, etc.
[0082] After receiving the request message sent by the first network device via the backhaul link, the second network device transmits the measurement data specified in the request message to the first network device via the backhaul link. The setting conditions for determining the coverage edge beam of the first network device may also include:
[0083] When the number of specific terminals that report measurement data corresponding to a certain beam to the first network device exceeds a set proportion of the total number of reporting terminals, the certain beam is determined as a coverage edge beam of the first network device.
[0084] In this embodiment, since a specific terminal accesses the first network device through a certain beam and reports measurement data, and also accesses the second network device through other beams and reports measurement data, when the number of specific terminals reporting corresponding to the certain beam to the first network device exceeds the total number of terminals reporting corresponding to the certain beam to the first network device, it means that the beam is located in the same coverage area of the first network device and the second network device. Therefore, the beam can be determined as the coverage edge beam of the first network device to facilitate subsequent optimization selection.
[0085] S40: When the total throughput of the terminal accessing the first network device through the coverage edge beam is greater than a set threshold, select the coverage edge beam to the optimized beam set of the first network device;
[0086] In some embodiments, the coverage edge beam determined above can be selected by setting a threshold value. The set threshold value can be a specific throughput value, a proportional relationship, or other values that can reflect the communication quality of the terminal accessing the first network device through the coverage edge beam. For example, when the total throughput of the terminal accessing the first network device through the coverage edge beam is greater than the set threshold, the coverage edge beam can be selected to the optimized beam set of the first network device, thereby determining the optimized beam set of the first network device in the optimized area to be covered. Each beam under the optimized beam set can provide a better communication experience for the accessed terminal, thereby achieving coverage optimization adjustment of the optimized area to be covered.
[0087] In some embodiments, whether to select the coverage edge beam into the optimized beam set of the first network device may be determined based on the total throughput of the specific terminal accessing the first network device via the coverage edge beam and the total throughput of the specific terminal accessing the second network device. For example, when the total throughput of all the specific terminals accessing the first network device via the coverage edge beam is greater than the total throughput of all the specific terminals accessing the second network device, it can be demonstrated that the communication quality of the specific terminal using the coverage edge beam is better than the communication quality using the beam of the second network device, and the coverage edge beam may be selected into the optimized beam set of the first network device.
[0088] The throughput of the above beam can be calculated based on the received signal power data, received signal signal-to-noise ratio data, and transmission channel estimation data reported by the terminal using relevant technical solutions, which will not be repeated here.
[0089] In summary, for a first network device in an area to be optimized for coverage, this embodiment obtains one or more beams under the first network device and configures measurement reference information for each beam. When a terminal accesses the first network device through a beam, the first network device sends a measurement reference signal corresponding to the beam to the terminal, so that the terminal measures the beam based on the received measurement reference signal and reports the measurement data to the first network device. The first network device determines one or more beams that meet set conditions as coverage edge beams of the first network device based on the received measurement data of each beam. Then, based on the total throughput of the terminal accessing the first network device through the coverage edge beam, it is determined whether to select the coverage edge beam into the optimized beam set of the first network device. When the total throughput exceeds a set threshold, it can be determined that the coverage edge beam meets the optimization condition and can be selected into the optimized beam set of the first network device. The optimized beam set finally selected by this embodiment can achieve coverage optimization adjustment of the area to be optimized for coverage by the first network device, so that all beams in the coverage area can provide users with a high network experience. The coverage area adjustment and optimization of this embodiment can be implemented when the terminal accesses the network device, and different coverage areas can be optimized independently based on measurement data, without adjusting the entire coverage area of the network device, thereby reducing the impact on user experience.
