Description
Technical Field
The invention relates to the technical field of 5G base stations, in particular to a dynamic configuration method of SSB beams in a 5G base station and the 5G base station.
Background
A5G New air interface (NR) divides communication channels into two categories, namely a synchronous broadcast control channel (SSB) and a service channel, and both channels adopt a beamforming method to improve coverage and reduce interference by combining the introduction of a Massive MIMO technology.
Compared with the synchronous/broadcast/control channel of 4G LTE, which uses a wide beam to transmit corresponding information in all cells, the 5G NR introduces a combination of beamforming and scanning in the synchronous broadcast control channel to transmit corresponding information, i.e., a cell coverage area is divided into N areas composed of narrow beams with the same beam width (N is determined by system-related configuration and device design). The 5G NR base station transmits beams of corresponding broadband in a beam forming mode, and transmits N broadcasting and synchronous narrow beams with fixed covering directions in a time division alternating mode to complete the broadcasting synchronous beam covering of the cell. When multiple narrow beams are possibly received by terminal users in a cell, the optimal beam (generally the strongest/best signal beam) is selected, and synchronization and demodulation of system messages are completed. Because the system converts the wide beam into the narrow beam, the energy of the system is more concentrated, and the coverage gain is greatly improved.
The coverage beam of the general 5G NR is divided into two types of horizontal and vertical coverage beams. Where N is the number of horizontal coverage beams, the beam width is generally a constant angle (e.g., 15 °), and the horizontal beam width is related to the number N. m is the number of vertical coverage beams, providing vertical coverage capability (e.g., high-rise coverage).
At present, a cell-level beam management scheme is used for beam management of a synchronous broadcast control channel by a main equipment manufacturer, namely, scene classification is carried out according to conditions such as buildings, signal environments, people flow distribution and service characteristics of a coverage area of a base station, typical coverage scenes such as dense urban area scenes, square scenes, high-rise scenes and cell interference scenes are determined, a broadcast beam of a 5G NR base station is covered by N (N > -1) beams with fixed beam widths (default scenes) according to the configured coverage scenes, and the broadcast beam coverage of a cell is completed in a mode of alternate scanning. The UE completes synchronization and system message demodulation by receiving the strong beam signal covering the position range of the UE, and system access is realized.
When the station is built and deployed, field workers of a network operator select a scene close to the site from typical scenes according to the surrounding environment and the people flow condition of the base station, and configure a beam mode of a corresponding base station synchronous broadcast control signal, so that the optimal coverage of the cell synchronous broadcast control signal is realized. However, on one hand, with the change of the environment of the coverage area of the base station, such as the construction of new buildings, the addition of new base stations around, and the change of the normal population distribution position of the coverage area, the signal coverage area of the base station is also changed. However, in the current mode of fixedly configuring the SSB beam, the beam configuration is generally not modified with the change of the external surrounding environment, so that the SSB signal coverage of the base station is not optimal, and even signals of the SSB beam cannot be received in some cases, thereby affecting the access of some users, and causing the traffic that can be absorbed by the base station to be not maximized. On the other hand, field personnel are required to configure the SSB beam coverage according to the actual coverage scene, so that the coverage scene cannot be defined in great detail, and can only be divided into a plurality of large categories of scenes, otherwise, ordinary construction personnel are inconvenient to select and configure, and thus the SSB beam coverage cannot be matched with the surrounding environment more accurately, and more accurate coverage is realized.

Detailed Description
For a more clear understanding of the technical features, objects and effects of the present invention, embodiments of the present invention will now be described in detail with reference to the accompanying drawings.
Examples
Referring to fig. 1, the method for dynamically configuring SSB beams in a 5G base station of this embodiment is applied to the 5G base station, where the 5G base station includes a memory for storing multiple SSB scene configuration parameters and an automatic configuration program for automatically reading and configuring the multiple SSB scene configuration parameters, and the 5G base station can automatically read and configure the multiple SSB scene configuration parameters by executing the automatic configuration program, so as to implement automatic configuration of the SSB beam scene parameters of the 5G base station. Alternatively, the various SSB scene configuration parameters stored in the memory of the 5G base station may be updated remotely on-line, so that the various SSB scene configuration parameters are kept in the latest classification state, and no staff is required to perform field configuration. On the basis, the optimal scene configuration parameters can be automatically selected by the embodiment, so that the 5G base station can reach the optimal working state. Specifically, the method for dynamically configuring the SSB beams in the 5G base station includes the following steps:
and S1 and the 5G base station sequentially execute a plurality of SSB scene configuration parameters, wherein each SSB scene configuration parameter corresponds to a 5G base station use scene. Each SSB scene configuration parameter includes various parameters for configuring software and hardware of the 5G base station, and the present embodiment classifies the usage scenes by comprehensively considering the situations of terrain, building distribution, number of people covered, service demand, and the like within the coverage area of the base station to obtain various SSB scene configuration parameters, where each SSB scene configuration parameter is different. For example, the plurality of SSB scene configuration parameters are rural scene configuration parameters, low-rise building scene configuration parameters, middle-rise building scene configuration parameters, high-rise building scene configuration parameters, special scene configuration parameters, and the like. And corresponding parameters are set for each scene, so that the 5G base station can realize the optimal coverage effect.
Further, considering that the environment is constantly changing, one scene may change to another scene over time. For example, if the buildings around the established base station are changed greatly, and a large number of buildings are newly built or removed, the previously configured scene parameters cannot adapt to the new scene, resulting in poor coverage of the 5G base station. In order to solve this problem, the 5G base station has an automatic configuration function, and can automatically configure various SSB scene configuration parameters, and select the SSB scene configuration parameter with the best performance to configure the 5G base station. The configuration process does not need the forward base station of the working personnel, so that the efficiency is high, and the labor cost is greatly saved.
The automatic configuration program of the 5G base station in this embodiment may automatically read and configure a plurality of SSB scene configuration parameters that are locally stored, and sequentially execute the plurality of SSB scene configuration parameters according to a preset execution sequence, where each SSB scene configuration parameter corresponds to one of the 5G base station usage scenarios; when the automatic configuration program configures certain SSB scene configuration parameters, the software parameters and the hardware parameters of the 5G base station need to be configured. And after the configuration is finished, the 5G base station starts to operate formally, and the 5G base station counts the network performance index of the 5G base station in the scene. Alternatively, the step of sequentially executing the multiple SSB scene configuration parameters by the 5G base station includes: the 5G base station executes one SSB scene configuration parameter and then automatically executes the next SSB scene configuration parameter after the preset time is reached until all the SSB scene configuration parameters are completely executed; and counting the network performance index of the 5G base station in the scene after executing one SSB scene configuration parameter, wherein the preset time can be flexibly set according to the requirement and can be one day, one week, one month and the like.
S2, comparing the network performance indexes of the 5G base station under each SSB scene configuration parameter, and selecting the SSB scene configuration parameter corresponding to the optimal network performance index to configure the 5G base station. And after executing all locally stored SSB scene configuration parameters, comparing the network performance indexes of the 5G base station in each scene, and selecting the SSB scene configuration parameters corresponding to the optimal network performance indexes to configure the 5G base station.

In this embodiment, the method for adaptively adjusting the SSB channel beam configuration parameters according to the change of the environment/user/service distribution of the coverage area of the 5G base station is used to achieve the best coverage effect, so that more users can obtain synchronization and broadcast control information, thereby achieving the access of the system and finally absorbing the service in the coverage area to the maximum extent.

The 5G base station also comprises an automatic configuration program for automatically reading and configuring the multiple SSB scene configuration parameters, and the 5G base station can automatically read and configure the multiple SSB main scene configuration parameters and the multiple SSB sub-scene configuration parameters corresponding to each SSB main scene configuration parameter by executing the automatic configuration program, so that the automatic configuration of the SSB beam scene parameters of the 5G base station is realized. Optionally, the multiple SSB main scene configuration parameters stored in the memory of the 5G base station and the multiple SSB sub-scene configuration parameters corresponding to each SSB main scene configuration parameter may be remotely updated on line, so that the SSB main scene configuration parameters and the SSB sub-scene configuration parameters are maintained in the latest classification state, and no staff is required to update on site, thereby saving labor cost. On the basis, the optimal scene configuration parameters can be automatically selected by the embodiment, so that the 5G base station can reach the optimal working state. Specifically, the method for dynamically configuring the SSB beams in the 5G base station includes the following steps:
s11, after determining the SSB main scene configuration parameters which enable the 5G base station to reach the network performance indexes, the 5G base station sequentially executes a plurality of SSB sub-scene configuration parameters corresponding to the SSB main scene configuration parameters, wherein each SSB main scene configuration parameter and each SSB sub-scene configuration parameter correspond to a 5G base station use scene.
Specifically, each SSB sub-scene configuration parameter is a further subdivision of the corresponding SSB main scene configuration parameter, so that the SSB main scene configuration parameter with the best network performance should be determined and selected first, and then an optimal SSB sub-scene configuration parameter is selected from the SSB sub-scene configuration parameters corresponding to the SSB main scene configuration parameter. For example, the various SSB main scene configuration parameters are rural scene configuration parameters, low-rise building scene configuration parameters, middle-rise building scene configuration parameters, high-rise building scene configuration parameters, special scene configuration parameters and the like, wherein the low-rise building scene configuration parameters comprise square open space scene configuration parameters, scene configuration parameters of interference among multiple base stations existing in surrounding adjacent cells, and low-rise building scene configuration parameters; the middle-layer building scene configuration parameters comprise middle-layer square scene configuration parameters, middle-layer building different vertical beam width scene configuration parameters and middle-layer covering interference scene configuration parameters; the high-rise building scene configuration parameters comprise high-rise and square scene configuration parameters, high-rise coverage and multi-base station interference scene configuration parameters and high-rise building scene configuration parameters; the special scene configuration parameters comprise narrow and long environment scene configuration parameters and wide beam (more than 120 degrees) scene configuration parameters of the expressway.
Referring to fig. 3, in this embodiment, after determining the SSB main scene configuration parameters that reach the network performance index, the 5G base station sequentially executes a plurality of SSB sub-scene configuration parameters corresponding to the SSB main scene configuration parameters, including:
s111, judging whether the network performance index of the 5G base station after executing a first preset period of a certain SSB main scene configuration parameter reaches a preset performance index.

S113, if the network performance parameter of the SSB main scene configuration parameter reaches the preset performance index, the 5G base station sequentially executes a plurality of SSB sub-scene configuration parameters corresponding to the SSB main scene configuration parameter. Specifically, the step of the 5G base station sequentially executing the plurality of SSB sub-scene configuration parameters corresponding to the SSB main scene configuration parameters includes: the 5G base station executes one SSB sub-scene configuration parameter and then automatically executes the next SSB sub-scene configuration parameter after reaching a second preset period until all the SSB sub-scene configuration parameters are completely executed; and counting the network performance index of the 5G base station in the scene after each SSB sub-scene configuration parameter is executed. Optionally, the first preset period is n times the second preset period, where each SSB main scene configuration parameter corresponds to n SSB sub-scene configuration parameters, and n is a positive integer.
Alternatively, the 5G base station executes one SSB main scene configuration parameter and then automatically executes the next SSB main scene configuration parameter after the preset time is reached until all the SSB main scene configuration parameters are completely executed; and counting the network performance index of the 5G base station in the scene after executing one SSB main scene configuration parameter.

S21, comparing the network performance indexes of the 5G base station under each SSB sub-scene configuration parameter, and selecting the SSB sub-scene configuration parameter corresponding to the optimal network performance index to configure the 5G base station.
In this embodiment, according to the change of the environment/user/service distribution condition of the coverage area of the 5G base station, the method for adaptively adjusting the SSB channel beam configuration parameters first determines the SSB main scene configuration parameters, and then further determines the SSB sub scene configuration parameters to achieve the optimal coverage effect, so that more users can obtain synchronization and broadcast control information conveniently, the access of the system is achieved, and finally, services within the coverage range are absorbed to the maximum extent.

and if the preset performance index is not reached, checking whether the coverage area of the 5G base station has special activity or not. In actual life, temporary large-scale activities may occur in a coverage area of a base station, or a temporary building may be built, and in this case, the influence of the temporary special activities on performance indexes should be eliminated, so as to ensure that the most suitable SSB main scene configuration parameters are found under normal conditions.

But considering that the environment is constantly changing, one scene may change to another scene over time. The SSB beam dynamic configuration method in the 5G base station in this embodiment may continuously monitor the network performance index of the 5G base station, and start the automatic configuration process again after finding that the network performance deteriorates below the network performance index, so as to ensure that the 5G base station always works on the network performance index. Specifically, after selecting the SSB scene configuration parameter configuration 5G base station corresponding to the optimal network performance index, the method further includes:
monitoring the network performance index of the 5G base station, and if the network performance index is reduced, re-executing the following steps:

The automatic configuration program of the 5G base station can automatically read and configure various SSB scene configuration parameters which are locally stored, and sequentially execute the various SSB scene configuration parameters according to a preset execution sequence, wherein each SSB scene configuration parameter corresponds to one 5G base station use scene.
