[0027] The configuration information generation method, apparatus, network device, and storage medium provided in the embodiments of this application will now be described in detail with reference to the accompanying drawings.
[0028] Furthermore, the terms “comprising” and “having”, and any variations thereof, used in the description of this application are intended to cover non-exclusive inclusion. For example, a process, method, system, product, or apparatus that includes a series of steps or units is not limited to the steps or units listed, but may optionally include other steps or units not listed, or may optionally include other steps or units inherent to such processes, methods, products, or apparatus.
[0029] It should be noted that in the embodiments of this application, the words "exemplary" or "for example" are used to indicate examples, illustrations, or explanations. Any embodiment or design scheme described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design schemes. Specifically, the use of the words "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.
[0030] In the description of this application, unless otherwise stated, "a plurality of" means two or more.
[0031] As described in the background art, in related technologies, the manual correction of RRUs after dual-segmentation results in significant errors, leading to inaccurate RRU correction and impacting user experience. Therefore, this application provides a configuration information generation method, apparatus, network device, and storage medium. When the beam isolation of the target antenna is greater than or equal to an isolation threshold, it indicates a high beam isolation of the target antenna, meaning higher accuracy in data transmission based on that target antenna. This can also be interpreted as higher reliability of the at least one PMI group information. In this case, the network device can accurately and effectively generate target configuration information. Furthermore, based on this target configuration information, the RRUs (i.e., at least two RRUs) corresponding to the network device can be accurately and effectively corrected, improving user experience.
[0032] For example, network devices that implement the configuration information generation method provided in the embodiments of this application may include base stations, evolved node base stations (eNBs), next-generation node base stations (gNBs), new radio eNBs, macro base stations, micro base stations, high-frequency base stations or transmission and reception points (TRPs), non-3rd generation partnership project (3GPP) access networks (such as WiFi) and / or non-3GPP interworking functions (N3IWFs), etc.
[0033] Optionally, taking a commonly used base station as an example, the hardware structure of the network device provided in this application embodiment will be described. For example... Figure 1 As shown, the base station provided in this application embodiment may include part 10 and part 11. Part 10 is mainly used for transmitting and receiving radio frequency signals and converting radio frequency signals to baseband signals; part 11 is mainly used for baseband processing and controlling the base station. Part 10 can generally be referred to as a transceiver unit, transceiver, transceiver circuit, or transceiver, etc. Part 11 is usually the control center of the base station and can generally be referred to as a processing unit.
[0034] The 10-part transceiver unit, also known as a transceiver or transceiver circuit, includes an antenna and a radio frequency (RF) unit, or may only include the RF unit or a portion thereof. The RF unit is primarily used for RF processing. Optionally, the devices in the 10-part unit that implement the receiving function can be considered as the receiving unit, and the devices that implement the transmitting function can be considered as the transmitting unit; that is, the 10-part unit includes both a receiving unit and a transmitting unit. The receiving unit can also be called a receiver, receiver circuit, or receiving circuit, and the transmitting unit can be called a transmitter, transmitter circuit, or transmitting circuit.
[0035] Part 11 may include one or more boards or chips. Each board or chip may include one or more processors and one or more memories.

The memories and processors may be integrated or independently configured. In some embodiments, Parts 10 and 11 may be integrated or independently configured. Furthermore, all functions in Part 11 may be integrated into one chip, or some functions may be integrated into one chip while other functions may be integrated into one or more other chips. This application does not limit this aspect.
[0036] like Figure 2 As shown, the configuration information generation method provided in this application embodiment may include S101-S103.
[0037] S101, The network device receives the feedback information sent by the terminal.
[0038] The returned information includes at least one PMI group information, and each PMI group information includes the phase of each antenna channel in multiple antenna channels and the amplitude of each antenna channel.
[0039] It should be understood that network devices can send downlink pilot signals to terminals. After receiving the downlink pilot signal, the terminal can perform channel state information reference signal (CSI-RS) measurement, that is, the terminal can measure and return CSI-RS information to the network device. This CSI-RS information can be understood as the aforementioned return information.
[0040] In one alternative implementation, the returned information (or CSI-RS information) may also include channel quality indicator (CQI) information and rank indicator (RI) information.
[0041] The network device in this application embodiment may consist of at least two BBUs, at least two remote radio units (RRUs), and a target antenna (i.e., the antenna corresponding to the network device), wherein the target antenna includes multiple antenna channels.
[0042] It is worth noting that the amplitude in the embodiments of this application can also be understood as the magnitude.
[0043] like Figure 3 As shown, port 201 of the target antenna can be connected to RRU 203, and port 202 of the target antenna can be connected to RRU 204.
[0044] It should be understood that when a network device includes two BBUs and two RRUs, the network device can be considered a dual-band network device (or dual-band base station). For example, if the network device includes two 4T4R (i.e., four transmit antennas and four receive antennas) BBUs and two 4T4R RRUs, then the network device is an 8T8R network device.
[0045] like Figure 4 The image shows an example of a dual-band base station provided in this application embodiment. Specifically, the dual-band base station 30 includes two BBUs (i.e., BBU 301 and BBU 302), two RRUs (i.e., RRU 303 and RRU 304), and an 8T8R antenna 305. The 8T8R antenna 305 includes 16 antenna channels, specifically 8 transmit channels and 8 receive channels.
[0046] Combination Figure 4 ,like Figure 5 As shown, the 8T8R antenna 305 can be located above the dual-band base station 30; two RRUs (RRU 303 and RRU 304) can be located in the middle of the dual-band base station 30, and the two RRUs can be connected to the 8T8R antenna 305 and the two BBUs (BBU 301 and BBU 302) respectively; the two BBUs can be located at the bottom of the dual-band base station 30. The 8T8R antenna 305 can achieve signal coverage and data transmission for relevant terminals (terminals 306, 307, and 308).
[0047] S102. The network device determines the beam isolation of the target antenna.
[0048] The beam isolation of the target antenna is used to characterize the accuracy of data transmission based on the target antenna, which is the antenna corresponding to the network device.
[0049] Combination Figure 2 ,like Figure 6 As shown, in one implementation of this application embodiment, the network device determines the beam isolation of the target antenna, which may specifically include S1021-S1022.
[0050] S1021. The network device obtains the radiated power of each beam in multiple azimuth angles of the target antenna.
[0051] Based on the description of the above embodiments, it should be understood that the target antenna is the antenna corresponding to (or included in) the network device.
[0052] It is understandable that these multiple beams are the beams emitted by the target antenna.
[0053] For example, the plurality of azimuth angles may include 0°, -60°, and 60°, etc.
[0054] S1022. The network device determines the beam isolation of the target antenna based on the radiated power of each beam at each azimuth angle.
[0055] It is worth noting that the beam isolation of a target antenna can reflect the correlation between orthogonal beams and the performance of a multiple-input multiple-output (MIMO) antenna. Network devices can accurately and effectively determine the beam isolation of a target antenna based on the radiated power of each beam at each azimuth angle.
[0056] Combination Figure 6 ,like Figure 7 As shown, in one implementation of this application embodiment, the network device determines the beam isolation of the target antenna based on the radiation power of each beam at each azimuth angle, which may specifically include S1022a-S1022b.
[0057] S1022a, The network device determines multiple power values.
[0058] Here, a power threshold corresponds to an azimuth angle, and the power value corresponding to an azimuth angle is the difference between the radiation power of the first beam at that azimuth angle and the radiation power of other beams at that azimuth angle. The first beam is one of the aforementioned multiple beams, and the other beams are the beams other than the first beam among the multiple beams.
[0059] In one alternative implementation, the first beam can be the largest radiating beam (or main lobe) among the plurality of beams.
[0060] S1022b: The network device determines the maximum value among multiple power values as the beam isolation of the target antenna.
[0061] It should be understood that the maximum value among these multiple power values can characterize the maximum radiated power difference between the first beam and other beams in these multiple azimuth angles. This maximum radiated power difference can accurately and effectively characterize the reliability of data transmission, that is, it can accurately and effectively characterize the beam isolation of the target antenna.
[0062] S103. When the beam isolation of the target antenna is greater than or equal to the isolation threshold, the network device generates target configuration information based on at least one PMI group information.
[0063] The target configuration information is used to correct the phase and amplitude of at least two RRUs, where the at least two RRUs are the RRUs corresponding to the network device.
[0064] It should be understood that when the beam isolation of the target antenna is greater than or equal to the isolation threshold, it indicates that the beam isolation of the target antenna is relatively high, meaning that the accuracy of data transmission based on the target antenna is high. This can also be interpreted as a high degree of reliability for the information from at least one PMI group. In this case, the network device can accurately and effectively generate target configuration information. Furthermore, based on this target configuration information, it can accurately and effectively correct the corresponding RRUs (i.e., at least two RRUs) of the network device.
[0065] Specifically, the network device can generate a corresponding PMI matrix based on the at least one PMI group information. The PMI matrix includes an amplitude weighting matrix and a phase weighting matrix. Then, the network device can perform mutual correction calculations based on the phase offset and amplitude gain of each of the multiple antenna channels to obtain the mutual correction factor matrix between the channels.
[0066] Alternatively, the above magnitude weighting matrix can be a p = [a0...a7], where p represents the p-th antenna channel, and the phase weighting matrix can be w q = [w0...w7], where q represents the q-th antenna channel.
[0067] The above mutual correction factor matrix can satisfy the following formula:
[0068]
[0069] Among them, h pq =a (p-q)*e jw(p-q) ,j=m+ni, where m and n are real numbers, i is the imaginary unit, and j is a complex number.
[0070] For example, when the network device includes two RRUs, that is, a dual-band RRU device, Table 1 below shows a comparison example of downlink RSRP, uplink average rate and downlink average rate under soft correction and hard correction for two 4T4R antennas and an 8T8R antenna, respectively.
[0071] Table 1
[0072]
[0073] As shown in Table 1, the performance of the 8T8R antenna is superior to that of the 4T4R antenna. Furthermore, hard calibration requires additional calibration equipment; therefore, soft calibration can be chosen as the calibration method for the RRU.
[0074] The technical solution provided by the above embodiments can bring at least the following beneficial effects: As shown in S101-S103, the network device can receive the feedback information sent by the terminal. This feedback information includes at least one PMI group information. Each PMI group information includes the phase and amplitude of each antenna channel in a plurality of antenna channels. Then, the network device can determine the beam isolation of the target antenna (i.e., the antenna corresponding to the network device). If the beam isolation of the target antenna is greater than or equal to the isolation threshold, it indicates that the beam isolation of the target antenna is large, meaning that the accuracy of data transmission based on the target antenna is high, which can also be understood as the reliability of the at least one PMI group information being high. At this time, the network device can accurately and effectively generate target configuration information. Furthermore, based on this target configuration information, the RRU (i.e., at least two RRUs) corresponding to the network device can be accurately and effectively corrected, improving the user experience.
[0075] Combination Figure 2 ,like Figure 8 As shown, the configuration information generation method provided in this application embodiment may further include S104.
[0076] S104. If the beam isolation of the target antenna is less than the isolation threshold, the network device deletes at least one PMI group information.
[0077] It should be understood that if the beam isolation of the target antenna is less than the isolation threshold, it indicates that the beam isolation of the target antenna is low, meaning that the accuracy of data transmission based on that target antenna is low. This can also be interpreted as a low reliability of the at least one PMI group information. In this case, deleting the at least one PMI group information from the network device can remove invalid PMI group information and save the network device's storage resources.
[0078] This application embodiment can divide network devices and the like into functional modules according to the above method examples. For example, each function can be divided into its own functional module, or two or more functions can be integrated into one processing module. The integrated module can be implemented in hardware or as a software functional module. It should be noted that the module division in this application embodiment is illustrative and only represents one logical functional division; other division methods may be used in actual implementation.
[0079] When dividing each function into modules according to its corresponding function.

[0081] The determination module 402 is used to determine the beam isolation of the target antenna, which is used to characterize the accuracy of data transmission based on the target antenna, and the target antenna is the antenna corresponding to the network device.
[0082] The processing module 403 is used to generate target configuration information based on the at least one PMI group information when the beam isolation of the target antenna is greater than or equal to the isolation threshold.

[0083] Optionally, the configuration information generation device 40 further includes an acquisition module 404.
[0084] The acquisition module 404 is used to acquire the radiated power of each of the multiple beams corresponding to the target antenna at each azimuth angle.
[0085] The determination module 402 is specifically used to determine the beam isolation of the target antenna based on the radiated power of each beam at each azimuth angle.
[0086] Optionally, the determining module 402 is further specifically used to determine multiple power values, wherein each power value corresponds to an azimuth angle, and the power value corresponding to an azimuth angle is the difference between the radiation power of the first beam at that azimuth angle and the radiation power of other beams at that azimuth angle, wherein the first beam is one of the multiple beams, and the other beams are beams other than the first beam among the multiple beams.
[0087] The determining module 402 is also specifically used to determine the maximum value among the multiple power values as the beam isolation of the target antenna.
[0088] Optionally, the configuration information generation device 40 also includes a deletion module 405.
[0089] The deletion module 405 is used to delete at least one PMI group information when the beam isolation of the target antenna is less than the isolation threshold.
