Description
Technical Field
The present invention relates to the field of wireless communication maintenance technologies, and in particular, to a wireless configuration method, a wireless configuration apparatus, an electronic device, and a storage medium.
Background
The 5G (5 th Generation Mobile Communication Technology, fifth Generation Mobile Communication Technology) system is designed to support three types of services, namely, eMBB (Enhanced Mobile Broadband), urlclc (Ultra-Reliable Low-Latency high-reliability Communication), and mtc (massive Machine Type Communication). The uplink and downlink time slot ratio of the 5G TDD (time division Duplex) base station of the existing network is generally configured with 7:3 double periods. 5363 a schematic diagram of a dual-period uplink and downlink timeslot of 7:3 may refer to fig. 1, 5 downlink timeslots, 2 special timeslots, and 3 uplink timeslots within 10ms, which are designed for an eMBB service mode mainly used by behaviors below a 2C (to subscriber) scenario. If the special timeslot ratio is 10 (10 downlink symbols, GP is 2 symbols, 2 uplink symbols) in the universal configuration, the number of downlink symbols in the 7:3 ratio is =14 × 5+10 × 2=90, and the number of uplink symbols is =14 × 3+2 × 2=46. Different from the 2C scenario, the eMBB service (e.g., video backhaul) of the 2B scenario often has a greater demand for uplink bandwidth, and the more reasonable uplink and downlink timeslot ratio is 2:3 monocycle. The schematic diagram of the 2:3 single-period uplink and downlink time slots can refer to 1 downlink time slot, 1 special time slot, and 3 uplink time slots in 5ms of fig. 2. Similarly, if the special timeslot ratio is also 10. It can be seen that the theoretical upward velocity of 2:3 is increased by 91.3% compared with 7:3.
However, when the 2:3 matching is applied in an outdoor scene, the uplink and downlink timeslot matching is not aligned, and the problem that the uplink signal is interfered by the inherent downlink signal in the TDD mode exists. The base station of 2:3 ratio is interfered by a peripheral 7:3 base station, RSSI (Received Signal Strength Indicator) is remarkably deteriorated, the 2:3 ratio scheme is difficult to truly deploy on the ground in an outdoor scene, and 5G uplink rate cannot be effectively increased.

Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Referring to fig. 3, a schematic diagram of signal interference of 7:3 single-period uplink and downlink timeslots to 2:3 single-period uplink and downlink timeslots is shown.
Because the proportion of 2:3 single-period uplink and downlink time slots is not aligned, and the problem that the uplink signal is interfered by the downlink signal inherent in the TDD system, 2:3 matches 7:3 on the periphery of the base station, and the proportion of No. 2, no. 3 and No. 7 downlink time slots of the base station can interfere 2:3 to match No. 2, no. 3 and No. 7 uplink time slots of the base station, especially No. 2 time slots; 3. timeslot 7 is usually not fully allocated with downlink symbols, and interference is slightly less but also exists. In addition, in an outdoor scene, due to the fact that natural shielding attenuation of buildings is different from that in an indoor scene, interference of periphery 7:3 on 2:3 matching base stations is more obvious in the outdoor scene. Even if the same-frequency deployment is avoided, the 7:3 and the 2:3 matching base stations adopt different-frequency deployment (for example, each 100M bandwidth), but no significant filtering truncation exists in the bandwidth of the existing network 3.5G frequency band equipment, so that the 2:3 matching scheme is difficult to land on the ground for deployment.
In the related art, there are three schemes for deployment:
1. bandwidth reduction, through frequency isolation.
2. The bandwidth is unchanged and isolated by frequency.
3. Bandwidth reduction, through frequency isolation.
For bandwidth reduction, a scheme of frequency isolation is used. Referring to fig. 4, a schematic diagram of a test point environment is shown. The central base station 0 is configured to be 2:3 in proportion, and is deployed with peripheral base stations (including a first-layer base station 1, a second-layer base station 2 and a third-layer base station 3) at the same frequency, for example, at 3400-3500 MHz (megahertz). Wherein, the first-layer base station 1 is a base station sector with a distance of about 800 meters from the central base station 0, and the total number of the base station sectors is 20; the second-layer base station 2 is a base station sector with a distance of 1200 meters from the central base station 0, and the total number of the base station sectors is 27; the three-tier base station 3 is a base station sector about 1500 meters away from the central base station 0, and the total number of sectors is 14. After actual deployment, the test points are tested, and the obtained indexes can refer to fig. 5.
It can be seen from fig. 5 that the RSSI degradation under this scheme, the UL (uplink) rate is very low, and the 2:3 ratio is completely without advantage compared to the uplink rate of 7:3 ratio. Even if the two parties leave out frequency band isolation through bandwidth reduction (respectively returning to 80MHz and 60 MHz), the problem cannot be solved; resulting in a 2:3 formulation that does not truly fall to the ground.
Aiming at the unchanged bandwidth, the central base station can be configured to be 2:3 ratio, 3500-3600 MHz and 100MHz bandwidth by a frequency isolation scheme; the ratio of the peripheral base station 7:3 is 3400-3500 MHz and the bandwidth is 100MHz. After actual deployment, the test points are tested, and the obtained indexes can refer to fig. 6a and fig. 6b.
As can be seen from fig. 6a and 6b, even though 2:3 is deployed with different frequencies of 3500-3600 MHz, the RSSI rise due to the misalignment of uplink and downlink timeslots is still significant. The method is directly changed into pilot frequency, the bandwidths of the two parties are kept at 100MHz, no obvious filtering truncation exists in the 200M bandwidth of the existing network 3.5G frequency band equipment, and the interference is still difficult to avoid.
Aiming at bandwidth reduction, a central base station is changed into 2:3 proportion, 3500-3600 MHz and 80MHz bandwidth through a frequency isolation scheme; the ratio of the peripheral base station 7:3 is 3400-3500 MHz and the bandwidth is 100/80/60MHz. After actual deployment, the test points are tested, and the obtained indexes can refer to fig. 7.
As can be seen from fig. 7, the RSSI of this scheme is better than the two schemes, which can be lower than-105 dBm (milliwatts); the improvement continues after the first landing is latched and can be below-110 dBm after 2, 3 landings are latched. The scheme also improves the UL rate, and can reach about 400Mbps (about 83% of the theoretical rate of 80M) under the bandwidth of 80M (megabits per second); the bandwidth of the peripheral 7:3 base station is reduced to 60M, which is better than the uplink rate of 80M/100M, 2. But there are problems with isolation in frequency by reducing the bandwidth. Specifically, if the base station in the isolation zone reduces the bandwidth, for example, from 100M to 80M and 60M (there are 90M, 70M, etc. options in the protocol), this requirement for the support of the 5G terminal capability may result in that the modified terminal that is normally used originally cannot access the 5G base station, and the loss of the downlink rate is large. If the central base station reduces the bandwidth, on one hand, the uplink capacity is influenced, the bandwidth loss is too much, and the meaning of 2:3 matching is lost, and on the other hand, the problem of terminal support capability is also existed.
In summary, the existing technical solutions all have defects, and the 2:3 matching base station cannot be deployed in a real landing manner. Therefore, the embodiment of the invention is provided, so that the 2:3 proportioning large uplink scheme of the base station can be really deployed on the ground.
Referring to fig. 8, a flowchart illustrating steps of an embodiment of a wireless configuration method according to the present invention is shown, which may specifically include the following steps:
when the uplink and downlink time slots of the operating band base station need to be adjusted to enable the operating band base station to adapt to the uplink bandwidth service, the service adaptation request can be received. The service adaptation request is used for requesting frequency modulation for the working band base station, so that the working band base station can be adapted to the uplink large bandwidth service. Wherein, the operating band base station may be a 5G toB base station deployed outdoors.
Related operators can send out service adaptation requests through the background management terminal equipment, and the terminal equipment for configuration management of the base station receives the service adaptation requests.
in the embodiment of the present invention, the service adaptation request carries an air interface parameter for performing wireless configuration on the operating band base station. After receiving the service adaptation request, the base stations of the operating band may be configured one by one according to the air interface parameters carried in the service adaptation request. The air interface parameters include, but are not limited to, a frequency band of the operating band base station, an uplink and downlink timeslot proportion, and a special timeslot proportion. Wherein, the ratio of the uplink time slot and the downlink time slot can be 2:3; the special slot allocation may be 6.
after the base station of the working band is configured, the base station sectors which need to be used for isolating signals of the base station of the working band are gradually screened out by diffusing to the periphery of the base station of the working band based on the base station of the working band as the center, and all the base station sectors which need to be isolated are determined as the base station sectors of the isolation band.
The downlink signal of the sector of the isolation zone base station can interfere with the uplink signal of the base station of the working zone. Therefore, a locking instruction can be sent to the terminal device of the sector of the base station of the isolation zone to lock the first target downlink time slot of the sector of the base station of the isolation zone. It should be noted that the first target downlink timeslot refers to a timeslot of a fully allocated downlink symbol in a downlink signal of a sector of an isolation zone base station, that is, a timeslot with large interference to an uplink signal of an operating zone base station. For example, when the ratio of the uplink timeslot and the downlink timeslot of the operating band base station is 2:3 and the ratio of the uplink timeslot and the downlink timeslot of the sector of the isolation band base station is 7:3, the first target downlink timeslot of the sector of the isolation band base station is the downlink timeslot No. 2.
When the embodiment of the invention is adapted to the uplink bandwidth service, a service adaptation request is received; configuring a working band base station based on the service adaptation request; screening isolation zone base station sectors based on the operating zone base station; and locking the first target downlink time slot of the sector of the isolation zone base station. The method comprises the steps that wireless configuration is carried out on a base station of a working band and a sector of a base station of a locking isolation band through pilot frequency configuration, and under the condition that the ratio of uplink time slots and downlink time slots of the base station of the working band is not aligned, signal interference of the sector of the base station of the isolation band is avoided without supporting a special bandwidth of the base station of the working band; the frequency band of the base station in the working band can be not reduced, the original bandwidth is kept for carrying out service processing, and the use of the terminal of the current network is not influenced; the time slot locking operation is easy to realize; therefore, the real floor deployment of the 5G big uplink scheme in an outdoor scene can be realized.
Referring to fig. 9, a flowchart illustrating steps of another embodiment of a wireless configuration method according to the present invention is shown, which may specifically include the following steps:
in the embodiment of the invention, the method can be applied to wireless configuration of the 5G base station. The 5G base station may be deployed indoors or outdoors. In a preferred example of the invention, the 5G toB base station is suitable for outdoor deployment.
When the different-frequency configuration needs to be carried out on a certain 5G toB base station, related operators can select and configure the base station through the number corresponding to the base station which is selected and configured by the base station management terminal equipment. The numbering manner may be a pure number, a pure letter, or a mixed coding manner, which is not specifically limited in this embodiment of the present invention. After a 5G toB base station (i.e., a working band base station) is selected, specific parameters to be configured, such as a frequency band, an uplink and downlink time slot ratio, a special time slot ratio, and the like, are input to generate a service adaptation request.
When the base station adapts the uplink bandwidth service, especially the uplink large bandwidth service, the service adaptation request sent by the base station management terminal equipment is received.
and after receiving the service adaptation request, configuring the frequency band of the base station of the working band, the uplink and downlink time slot ratio and the special time slot ratio. And respectively adjusting the original frequency band, the original uplink and downlink time slot ratio and the original special time slot ratio of the operating band base station to the frequency band, the uplink and downlink time slot ratio and the special time slot ratio of the operating band base station corresponding to the service adaptation request. Specifically, the operating band base stations are configured as inter-frequency (i.e., different frequency bands than the isolation band base stations). The uplink and downlink time slot ratio 2:3, the special time slot ratio 6.
in the embodiment of the invention, after the base station of the working band is configured, the sector of the base station of the isolation band which needs to be adjusted after the pilot frequency configuration of the base station of the working band is screened out by taking the base station of the working band as the center of a circle according to the environment of the base station of the working band. That is, reference may be made to fig. 10 for the division of the base stations, the innermost side is a working band base station, and the uplink and downlink time slots are configured in a ratio of 2:3; the isolation zone base station surrounds the working zone base station, and the uplink and downlink time slots of the isolation zone base station are 7:3 in proportion; the base station of the large network surrounds the base station of the isolation zone, and the uplink and downlink time slots of the base station of the large network are proportioned 7:3.
In an optional embodiment of the present invention, the step of screening sectors of the base station in the isolation zone based on the base station in the operating zone includes:
substep S9031, acquiring geographic position information, base station switching information and road test information corresponding to the work band base station;
in practical application, the geographical position information, the base station switching information and the road test information corresponding to the work band base station can be obtained from a database in which the base station information is stored. The geographical position information corresponding to the operating band base station comprises an actual geographical position of the operating band base station and a base station sector geographical position within a preset range of the geographical position. The geographic location may be represented in latitude and longitude coordinates. The predetermined range may be determined based on the signal coverage of the operating band base station, such as within 2000 meters, etc. The specific range is not limited. The base station switching information is based on neighbor cell level, the statistics information of the number of times of pairwise switching between the base station of the working band and other base station sectors, and the number of times of switching between the base station of the working band and other base station sectors and the identification of the corresponding base station sector are recorded. The road test information is information for performing signal strength test recording on the road around the base station of the working band.
Further, in order to reduce the data processing amount of the base station switching information, the base station switching information may be preprocessed in advance to screen out base station sectors having a large relationship with the base station of the operating band. The threshold for screening may be determined by those skilled in the art according to the actual request of the operating band base station, and is not particularly limited.
Substep S9032, determining a first base station sector subset of the isolation zone based on the geographical location information;
for the geographical location information, a base station of the isolation zone may be determined based on a geographical location relationship of the base station sector and the working zone sector, and a first subset of sectors of the base station of the isolation zone may be generated based on the base station of the isolation zone.

and after screening out the base station sector of the isolation zone, sending a time slot locking instruction to the base station sector of the isolation zone, so that the base station sector of the isolation zone locks the first target downlink time slot after receiving the time slot locking instruction. The specific form and content of the timeslot blocking instruction may be related to the device type of the base station in the isolation zone according to the sector of the base station in the isolation zone, and a person skilled in the art may adopt a timeslot blocking instruction matched to the device type according to the device type related to the base station in the isolation zone. The specific content of the slot lock instruction is not particularly limited. Specifically, referring to fig. 11, when the sector of the isolated zone base station is the ratio of the uplink timeslot to the downlink timeslot of 7:3, the No. 2 downlink timeslot may be locked.
In practical application, the field wireless environment of the base station of the isolation zone and the sector of the base station of the isolation zone can be operated, the beam of the synchronous signal block and the power of the synchronous signal block of the sector of the base station of the isolation zone are adjusted, and the interference of the sector of the base station of the isolation zone is further avoided. Specifically, referring to fig. 12, the SSB beam (synchronization signal block beam) of the isolated zone base station may be adjusted to a single beam. Moreover, in order to compensate for the deterioration of the coverage of the base station in the isolation band after the adjustment to the single beam, the SSB power (synchronization signal block power) can be increased.
In an optional embodiment of the invention, the method further comprises:
step S1, testing the received signal strength of the base station in the working band, and determining a received signal strength indicated value;
after the initial configuration of the base stations of the working band and the sectors of the base stations of the isolation band is completed, the strength of the received signals of the base stations of the working band can be tested, the indicated value of the strength of the received signals is determined, and the coverage condition of the base stations of the working band is evaluated.
Step S2, when the received signal strength indicated value is smaller than a preset strength threshold value; performing the step of screening the base station sectors of the isolation zone based on the base station of the operating zone;
when the received signal strength indicating value is smaller than the preset strength threshold value, which indicates that the interference phenomenon still exists at present, the step of screening the sector of the isolation zone base station can be executed again, and the sector of the isolation zone base station is further increased to enlarge the isolation zone and further reduce the signal interference.
And S3, locking a second target downlink time slot of the base station sector of the isolation zone when the number of the base station sector of the isolation zone is a preset number threshold.
The preset number threshold may be a value of the sector of the base station of the isolation zone without omission, that is, when the number of the sector of the base station of the isolation zone is the preset number threshold, it indicates that all the base stations of the isolation zone have been brought in, and there is no newly added sector of the base station of the isolation zone, and at this time, the second target downlink timeslots of all the sectors of the base station of the isolation zone may be locked. And the second target downlink time slot is a time slot which has little influence on the uplink time slot of the base station in the working band and does not completely configure downlink symbols. For example, when the ratio of the uplink timeslot and the downlink timeslot of the sector of the isolated base station is 7:3, the second target downlink timeslot may be timeslot number 3 or timeslot number 7. At the moment, the downlink time slot of the sector of the base station of the isolation zone is locked, and the interference of the downlink time slot of the sector of the base station of the isolation zone on the uplink time slot of the sector of the base station of the working zone is reduced.

The method comprises the steps that wireless configuration is carried out on a base station of a working band and a sector of a base station of a locking isolation band through pilot frequency configuration, and under the condition that the ratio of uplink time slots and downlink time slots of the base station of the working band is not aligned, signal interference of the sector of the base station of the isolation band is avoided without supporting a special bandwidth of the base station of the working band; the frequency band of the base station in the working band can be not reduced, the original bandwidth is kept for carrying out service processing, and the use of the terminal of the current network is not influenced; the time slot locking operation is easy to realize; and the coverage condition of the base station in the working band after the actual deployment test can reach the target coverage condition, so that the real floor deployment of the 5G large uplink scheme in an outdoor scene can be realized.
In order to enable a person skilled in the art to better understand the embodiments of the present invention, the following description is given by way of an example:

Referring to fig. 14, a base station of a work band is indicated by the icon 100.
And step two, screening the isolation zone base stations.
Based on geographical adjacency (geographical location information), switching relationship (base station switching information) and actual road test, 11 sectors of peripheral stations are screened out to be brought into isolation zones, specifically, reference can be made to fig. 14, wherein 7 sectors belong to the 1 st landing 201,4 and 7 sectors belong to the 2 nd landing 202.
And step three, locking part of downlink time slots of the sector of the isolation zone base station.
Slot No. 2 of 11 sectors of the isolation zone is blocked.
Step four, adjusting SSB wave beam of isolation zone base station sector
The SSB of 11 sectors of the isolation zone is adjusted to be a single beam (no further adjustment is made to the SSB power). Specifically, the beam adjustment list is as follows:
and step five, evaluating the base station RSSI of the working band.
And after the step one to the step four are executed, 3 sectors of the base station of the working band are tested, and the RSSI of the base station of the working band in 24 hours is lower than-100 dBm, so that the requirements are met. Specifically, as for the test index of the actual test, referring to fig. 15, 2:3 matching of the actual test outdoor scene, the uplink peak rate may reach 524Mbps, which is about 87% of the theoretical uplink peak rate (100M bandwidth, 2:3 matching, 2T terminal, 64qam, and 5g theoretical uplink peak rate calculates about 602 Mbps).
