Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The terms "first," "second," and the like in the description and in the claims, and in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the invention described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
Before introducing the embodiments of the present application, the background of the present application will be explained first.
The beamforming technology is a technology that by adjusting the amplitude and phase of the transceiver unit of each antenna array, the transmitting/receiving signals of the antenna array in a specific direction are mutually superposed, and the signals in other directions are mutually offset. The beamforming technology greatly improves the system capacity and the spectrum utilization rate of 5G.
For a 5G network, a multiple-in multiple-out (MIMO) technology and a beamforming technology are the most important 2 of wireless air interface technologies. The multi-user MIMO technology realizes the multiplexing of user data at an air interface, the beamforming technology solves the problems of large medium-high frequency signal loss and poor coverage effect, and on the basis, optimizing personnel can exert the coverage efficiency of the wireless base station to the maximum extent as long as the optimizing personnel can accurately position the occurrence position of the user communication service and select proper beamforming parameters.
In the existing 5G beam configuration selection technical scheme, polling type beam configuration is mainly performed on cells, and finally, a beam configuration corresponding to the optimal air interface performance is selected by comparing cell performance indexes of each type of beam configuration.
However, in the actual process, the prior art has the following problems:
1. the period of the beam configuration is long: because each cell needs to select 1 Single Side Band (SSB) primary scene configuration, and then sequentially execute a plurality of SSB secondary scene configurations. In order to ensure the objectivity of the comparison data, each configuration combination needs to be kept for at least several days, so that the whole configuration selection period is long in time;
2. the impact of the time dimension on the beam configuration is neglected: for example, a cell covering an office building performs different beam configuration comparisons on weekends and non-weekends, and the user scale, index performance, and the like cannot be directly used for comparison.
In view of the above technical problems, the inventive concept of the present application is as follows: in the process of configuring the beam, the inventor finds that the selection principle of the beam configuration can be returned to the basic technical principle, wherein the difficulty is that the wireless environment is a relatively complex individual, the information such as the height, the floor area and the like of a building cannot be obtained by the current two-dimensional map, and at the moment, the building information can be extracted by virtue of the advantages of the three-dimensional map, the problem of complex wireless environment is solved, and the beam configuration of different cells in different wireless environments is solved.
The technical solution of the present application will be described in detail below with reference to specific examples.
Table 1 shows 17 commonly used beamforming types provided in the embodiments of the present application. Table 2 provides specific coverage scenario types for embodiments of the present application.
Specifically, a suitable beamforming mode pattern may be selected according to a specific coverage scenario of each cell, so as to improve the system capacity and the spectrum utilization of 5G.

The coverage scene is square + middle-level building, and the beam with wider horizontal and vertical is used in the figure, so that the coverage of the horizontal plane and the vertical range is ensured.
As another example, fig. 2D is an application schematic diagram under Pattern 1 provided in the embodiment of the present application. The coverage scene is a square, and a beam with a wider horizontal range is used, so that the coverage efficiency of the wireless base station is furthest exerted when the beam forming is accessed.
Based on the above examples, several specific embodiments are combined to describe the present application, and the description of the same or similar concepts is omitted.
Fig. 3 is a flowchart of a first embodiment of a beam configuration method according to an embodiment of the present application. As shown in fig. 3, the beam configuration method may include the steps of:
and step 31, rasterizing the 5G capability information reported by the UE according to the pre-acquired full measurement report and the preset grid size to obtain a coverage grid of each 5G cell.
In this scheme, in order to determine a target beam configuration mode corresponding to each 5G cell, first, a Measurement Report (MR) of each 5G cell needs to be obtained. The full MR is used for network evaluation for each 5G cell.
In one possible implementation, fig. 4A is a schematic diagram of a current network architecture for acquiring a full MR according to an embodiment of the present application. As shown in fig. 4A, the current network architecture is schematically illustrated as a 5G Non-dependent Networking (NSA) 3X, including: the system comprises a 4G Core network (EPC), a 4G base station, a 5G base station, a mobile phone (terminal) and a shunt control point.
The Long Term Evolution (LTE) -base station eNB serves as a dual-connected primary node MeNB and carries control plane and user plane data, the terminal accesses the EPC through the LTE eNB (4G base station), and the NR gbb (5G base station) serves as a secondary node and carries user plane data.
Optionally, table 3 is a partial procedure for acquiring a full MR provided in the embodiment of the present application; fig. 4B is a schematic diagram of a large data platform according to an embodiment of the present disclosure. Specifically, the acquisition of the total MR will be described with reference to fig. 4A in conjunction with table 3 and fig. 4B.
Table 3:
specifically, when the terminal with the NSA function accesses the EPC, the UE MR-DC Capability in the User Experience (UE) Capability event reports the 5G Capability to the EPC, then the EPC issues a B1 measurement (see "eventB 1_ NR _ r 15" in table 3), and the 5G (5G New Radio, NR) frequency information that needs to be measured by the terminal is sent to the terminal through a Radio Resource Control (RRC) reconfiguration message. And the terminal acquires the NR synchronous signal after receiving the NR synchronous signal, measures the quality of the 5G signal and reports the measurement result to the EPC.
The measurement result exists in a log file Message Logs, the EPC stores the measurement result in an Operation Support System (OSS) vendor, and a big data Analysis platform Geo Analysis acquires the measurement result in the OSS vendor. The Trace of the operation support system is used for debugging a request-response protocol http mode connected with the network server; the EN-DC (EUTRA-NR Dual Connection) X2 uses the Dual Connection of a 4G MeNB as a main node and an SgNB as a secondary node, and is used for providing service for the terminal.
In this step, according to the measurement result, determining latitude and longitude information of each sampling point in the full MR, screening out B1 events related to NR in the full MR, and rasterizing the 5G capability information reported by the UE with a preset grid size to obtain a coverage grid of each 5G cell.
In one possible implementation, the B1 event related to NR in the full MR may be used to represent Reference Signal Received Power (RSRP), and fig. 4C is a schematic diagram of a coverage grid provided by an embodiment of the present application. As shown in fig. 4C, the preset grid size may be 50m × 50m, each grid replaces RSRP that may be in the range of 50m × 50m, and the coverage grid with RSRP in the range of 95% to 100% is illustrated in the figure, and a schematic diagram of 93% to 95%, 88% to 93%, 80% to 88%, 70% to 80%, and 0% to 70% of the coverage grid may be included.
And 32, acquiring morphological characteristic information of the building covered by each 5G cell based on the 3D electronic map and the coverage grid of each 5G cell.
In this step, in order to more accurately determine the coverage scene type of the 5G cell, firstly, the wireless environment of the 5G cell needs to be accurately obtained, and the wireless environment can be obtained by a 3D electronic map, and then, according to the information in the 3D electronic map and the coverage grid of each 5G cell obtained in the above step, the morphological feature information of the building covered by each 5G cell is determined.
Optionally, vector information and height information of the building are obtained according to the 3D electronic map, and then the outline information of the building is determined based on the vector information and the height information.
In one possible implementation, in a buildVector file in the 3D electronic map of the input source, height information of a building (described in a subfile attribute of the buildVector) and vector information of the building (described in subfiles of the buildVector, including a coordinate collection of the building) are obtained.
