Description

Interference management method, device and storage medium

Technical Field

The present application relates to the field of communications technologies, and in particular, to an interference management method, an interference management apparatus, and a storage medium.

Background

A fifth generation mobile communication technology (5G) base station supports more channels, and a large-scale antenna array is adopted to support a large-scale antenna technology (large-scale multiple-input-output, large-scale MIMO) to greatly improve network performance. A 5G base station supporting massive MIMO technology may transmit multiple beams, with different beams covering different areas. The coverage requirements of different scenes can be met by a multi-beam transmitting mode, and the space coverage performance of the network is improved. When each User Equipment (UE) connected to the 5G base station accesses the network, a beam with the maximum signal strength may be selected and accessed through beam measurement.

In order to avoid interference between beams, in the prior art, the coverage of beams is controlled by presetting the coverage parameters of the beams, and beams with the same frequency are staggered in space to avoid mutual interference.

In the general technology, when a UE selects an access beam, the UE selects a beam to be accessed based on the signal intensity of the beam measured by a single UE. This approach may result in different UEs located close together or in the same geographical area accessing different beams, thereby causing some of the closely located UEs to be scattered over different beams. Thus, the 5G base station is difficult to avoid interference between different beams by being spatially shifted, and the effect of interference suppression is reduced.

Any embodiment or design described herein as "exemplary" or "e.g.," is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, use of the word "exemplary" or "such as" is intended to present concepts related in a concrete fashion.

As described in the background art, the 5G base station supports more channels, and a large-scale antenna array is adopted, so that the massive MIMO technology is supported, and the network performance is greatly improved.

The Massive MIMO refers to that a transmitting end and a receiving end respectively use a plurality of transmitting antennas and receiving antennas to transmit and receive signals, the phase of an antenna array is adjusted in a self-adaptive mode through a beam forming technology, a plurality of energy-concentrated narrow beams pointing to a specific area are formed, and the channel capacity and the signal coverage range of a system are improved.

The 5G base station equipment can emit a plurality of wave beams, different wave beams cover different areas, the covering requirements of different scenes are met through a multi-wave-beam emitting mode, and the space covering performance of the network is improved. When each terminal accesses the network, the beam with the maximum signal intensity is selected and accessed through beam measurement.

In order to improve the spectrum utilization efficiency, a mobile communication network usually adopts a networking mode of frequency reuse, and adjacent beams use the same spectrum resource, so that mutual interference occurs between different beams, and the network performance is affected. For the downlink direction, the downlink signal of the interfering beam falls into the terminal receiver under the interfered beam, which causes downlink interference to the terminal under the interfered beam.

In the general technology, when a terminal selects an access beam, the beam to be accessed is selected based on the intensity of a beam signal measured by a single terminal, which may cause different terminals located in the same geographical area and close in position to access different beams, the terminals are dispersed on different beams, interference between different beams is difficult to avoid in a spatially staggered manner, the interference suppression effect is limited, and the target of inter-beam interference suppression cannot be realized.

In view of the above problem, an embodiment of the present application provides an interference management method, which may obtain location information of a plurality of terminals in a preset area, and divide the plurality of terminals into at least one terminal cluster based on the location information. Then, at least one beam corresponding to at least one terminal cluster in a one-to-one manner may be determined, and for each terminal of the plurality of terminals, each terminal is controlled to access the beam corresponding to the terminal cluster to which it belongs. Therefore, the number of beams accessed by the terminal in the preset area can be reduced, and the inter-beam interference suppression effect is improved.

The interference management method is suitable for an interference management system. The interference management system may be adapted to a preset area. The preset area is an arbitrarily defined area in the network and comprises at least one base station. Each base station may support at least one beam (supporting beamforming techniques).

As shown in fig. 4, the interference management method provided in the embodiment of the present application is applied to the interference management module shown in fig. 1. The interference management method comprises the following steps:

Specifically, the interference management module may send a terminal location information request message to each base station in a preset area, where the terminal location information request message carries preset historical time information.

The preset historical time is a time period before a preset first cycle, and comprises a plurality of unit time periods, and the length of each unit time period is the same as the preset second cycle.

Each base station in the preset area can acquire the position information of all terminals accessed to the base station according to a preset second period, and sends a terminal position information report message to the interference management module, wherein the terminal position information report message carries the position information of each terminal in a preset historical time.

After obtaining the position information of the plurality of terminals in the preset area, the interference management module may adopt a preset algorithm to divide all the terminals in the preset area into terminal clusters, and determine the terminal cluster parameters.

The preset area can contain at least one terminal cluster, and different terminal clusters can be uniquely distinguished through terminal cluster identifiers.

The terminal cluster parameter includes a terminal cluster identifier and an identifier list of each terminal included in the terminal cluster.

The preset algorithm is used for dividing the terminals with similar position characteristics into the same terminal cluster, so that the terminals in the same terminal cluster are located in the same geographic area, and the received signal intensity of each beam has similarity with the interference condition among the beams.

S402, the interference management module executes a first operation aiming at least one terminal cluster so as to obtain at least one beam corresponding to the at least one terminal cluster one by one.

Wherein the first operation comprises: and acquiring target beam measurement information of each target terminal in the target terminal cluster. The target beam measurement information includes: signal strength value and signal quality value. And determining a target beam corresponding to the target terminal cluster according to the target beam measurement information. The target terminal cluster is any one of at least one terminal cluster; the target terminal is any terminal in the target terminal cluster.

Optionally, the obtaining, by the interference management module, target beam measurement information of each target terminal in the target terminal cluster includes:

an interference management module receives beam measurement information indication messages sent by a plurality of base stations in the preset area; the beam measurement information indication message includes: beam measurement information corresponding to terminals served by a plurality of base stations and identifications of the plurality of base stations; the beam measurement information indication message is sent after the beam measurement report messages sent by a plurality of terminals in a preset area are received by a plurality of base stations; the beam measurement report message includes beam measurement information; the beam measurement information comprises a terminal identifier, a beam frequency, a beam identifier and corresponding beam signal strength and signal quality;

if one terminal belongs to the target terminal cluster, the interference management module determines the beam measurement information corresponding to the one terminal as the target beam measurement information.

Specifically, each terminal in the preset area may send a beam measurement report message to the plurality of base stations according to a preset second period, where the beam measurement report message carries beam measurement information corresponding to each terminal.

The beam measurement information includes a terminal identifier, a beam frequency, a beam identifier, and a corresponding beam signal strength and signal quality. One beam measurement information corresponds to one terminal identifier, and one beam measurement information comprises at least one beam identifier and corresponding beam signal strength and signal quality.

Wherein, the signal strength of a beam is defined as a reference signal power value of the beam measured by the terminal. The signal quality of a beam is defined as the ratio of the reference signal to the interference noise of that beam as measured by the terminal.

S403, the interference management module controls one terminal to access a beam corresponding to a terminal cluster to which the terminal belongs, for each terminal in the plurality of terminals.

Wherein, one terminal is any one of a plurality of terminals.

Specifically, the interference management module may send a beam access request message to a base station to which each target terminal in the target terminal cluster is accessed. The target beam identifier and the target terminal cluster parameter are carried in the target beam identifier and the target terminal cluster parameter.

And the base station accessed by each target terminal sends a beam access indication message to each target terminal, wherein the beam access indication message carries a target beam identifier.

And after receiving the beam access indication message, each target terminal accesses the target beam.

As can be seen from the above description, each terminal generally accesses the beam with the largest signal strength based on the measurement of the signal strength of each beam. This will cause different terminals located in the same area to access different beams, increasing the number of beams accessed by the terminals in the area, and increasing the inter-beam interference. In the application, after the interference management module determines the terminal cluster and the corresponding target wave beam, the terminals in the same terminal cluster are controlled to access the same target wave beam in a message sending mode, so that the number of wave beams accessed by each terminal in the terminal cluster can be reduced, and the inter-wave beam interference suppression effect is improved.

In an embodiment, with reference to fig. 4 and as shown in fig. 5, after the interference management module controls, for each terminal of the multiple terminals, one terminal to access a beam corresponding to a terminal cluster to which the one terminal belongs, the method further includes:

s501, the interference management module executes a second operation on at least one terminal cluster to obtain at least one interference beam corresponding to the at least one terminal cluster one to one.

Wherein the second operation comprises: and determining at least one downlink interference beam according to the target beam measurement information of each target terminal in the target terminal cluster. And determining the average value of the average signal strength values of at least one downlink interference beam as the downlink interference value of the target terminal cluster. And if the downlink interference value of the target terminal cluster is greater than a preset interference threshold value, determining a target interference beam corresponding to the target terminal cluster according to the edge service load of each downlink interference beam.

Specifically, the interference management module may determine the downlink interfering beam according to the target beam measurement information. Next, the interference management module may determine a downlink interference value of the target terminal cluster.

In an implementation manner, the interference management module may first determine an average value of the average signal strength values of at least one downlink interference beam as a downlink interference value of the target terminal cluster.

Specifically, the downlink interference value may be defined as an average value of average signal strength values of at least one downlink interference beam.

After each terminal in the target terminal cluster is accessed into the target wave beam, because a plurality of wave beams may exist in the area where the target terminal cluster is located, the downlink interference wave beam and the downlink interference value which cause interference to the target terminal cluster are determined by obtaining the wave beam measurement information of each terminal in the target terminal cluster.

And the downlink interference value is used for reflecting the magnitude of downlink interference suffered by the target terminal cluster, and when the downlink interference is large, the interference suffered by each terminal in the target terminal cluster is reduced by further determining a target interference beam and adjusting the coverage parameter of the target interference beam.

And if the downlink interference value of the target terminal cluster is greater than a preset interference threshold value and the edge service load of the downlink interference beam is less than a preset load threshold value, determining the downlink interference beam as the target interference beam.

Correspondingly, if the downlink interference value of the target terminal cluster is smaller than or equal to the preset interference threshold, or the edge service load of the downlink interference beam is greater than or equal to the preset load threshold, the target interference beam does not need to be determined.

S502, the interference management module sends a beam adjustment request message.

The beam adjustment request message is used for requesting at least one interference beam to adjust the coverage parameter of the at least one interference beam according to a preset rule.

Specifically, the interference management module may send a beam adjustment request message to a target base station where the target interfering beam is located, where the beam adjustment request message carries a target interfering beam identifier.

After receiving the beam adjustment request message, the target base station may adjust the coverage parameter of the target interfering beam according to a preset rule.

The coverage parameter of the beam comprises at least one of the parameters of the width, the transmitting power and the like of the beam.

The beam width can be defined as the angle between two points where the radiation intensity decreases by 3dB on both sides of the maximum radiation direction of the main lobe of the beam. The smaller the lobe width is, the better the beam directivity is, and the stronger the anti-interference capability is.

The beam transmitting power is the power value allocated to the beam by the base station where the beam is located. The larger the beam transmitting power, the longer the coverage distance, and the stronger the interference to the terminal under other adjacent beams.

In one embodiment, the preset rules include:

if the width of the target disturbing beam is not less than the preset minimum wave width and the transmitting power is not less than the preset minimum power, the width of the target disturbing beam is reduced by a preset angle step value, and/or the transmitting power of the target disturbing beam is reduced by a preset power step value.

For example, if the width of the current target interfering beam is not less than the preset minimum bandwidth and the transmission power is not less than the preset minimum power, the width of the target interfering beam is decreased by a preset angle step value or/and the transmission power of the target interfering beam is decreased by a preset power step value.

And the target base station acquires target beam measurement information corresponding to the target terminal cluster of the next second period again, wherein the target beam measurement information comprises beam measurement information corresponding to at least one target terminal in the target terminal cluster. The beam measurement information corresponding to each target terminal comprises at least one beam identifier and a corresponding beam signal strength value.

And the target base station determines the average signal strength value of the target interference beam according to the target beam measurement information. That is, the average value of the target interfering beam signal strength values measured by at least one target terminal in the target beam measurement information.

And the target base station compares the average signal strength value of the target disturbing wave beam with a preset first signal strength threshold value. And if the average signal intensity value of the target disturbing wave beam is not greater than a preset first signal intensity threshold value, determining the current wave beam width and the wave beam transmitting power as the coverage parameters of the adjusted target disturbing wave beam.

Correspondingly, if the average signal strength value of the target disturbing beam is greater than the preset first signal strength threshold value, the target disturbing beam is continuously adjusted until the average signal strength value corresponding to the adjusted target disturbing beam is smaller than the first signal strength threshold value.

In the general technology, the coverage parameters and the corresponding coverage ranges of the beams are preset, and cannot be dynamically adjusted based on the position change of the terminal and the real-time interference condition, so that the interference suppression requirement of the terminal is difficult to meet in real time, and the service performance of the terminal is influenced.

In the method, the target base station adjusts the coverage parameter of the target interference beam according to a preset step length until the average signal intensity value of the beam is not greater than a preset first signal intensity threshold value. The method and the device realize that the average signal intensity value of the target disturbing beam is reduced by adjusting the coverage parameter of the target disturbing beam, thereby reducing the interference on the target terminal cluster.

In an embodiment, referring to fig. 5 and as shown in fig. 6, in the above S401, the method for acquiring location information of a plurality of terminals in a preset area by an interference management module and dividing the plurality of terminals into at least one terminal cluster based on the location information specifically includes:

s601, the interference management module acquires position information of a plurality of terminals in a preset area in each unit time period in preset historical time.

S602, the interference management module inputs position information of a plurality of terminals in a preset area in each unit time period in preset historical time into a clustering model to obtain at least one terminal cluster.

Specifically, the interference management module may acquire position information of all terminals in a preset region in each unit time period within a preset historical time, and input the position information as sample data into the clustering model to obtain at least one terminal cluster.

Optionally, the Clustering model may adopt a K-means Clustering algorithm (K-means Clustering, K-means), a system Clustering algorithm, a Density-Based Clustering algorithm (Density-Based Spatial Clustering of Applications with Noise, DBSCAN), and other models.

In an embodiment, referring to fig. 5 and as shown in fig. 7, a method for acquiring location information of a plurality of terminals in a preset area by an interference management module and dividing the plurality of terminals into at least one terminal cluster based on the location information specifically includes:

s701, the interference management module acquires position information of a plurality of terminals in a preset area in each unit time period in preset historical time.

S702, the interference management module performs a third operation on each of the plurality of terminals to obtain at least one terminal cluster.

Wherein the third operation comprises: and determining the distance between the first terminal and the second terminal according to the position information of the first terminal and the position information of the second terminal in a unit time period in a preset historical time. And if the distance is smaller than the preset distance, determining a unit time period as a first unit time period. And if the ratio of the number of the first unit time periods in the preset historical time to the total number of the unit time periods is greater than a preset ratio, determining that the first terminal and the second terminal are the same terminal cluster.

For example, the interference management module may obtain location information of all terminals in a preset area in each unit time period within a preset historical time.

In a certain unit time period in the preset historical time, if the distance between the terminal 1 and the terminal 2 is smaller than a preset third threshold, determining the unit time period as a first unit time period.

And if the ratio of the number of the first unit time periods to the total number of the unit time periods in the preset historical time is greater than a preset fourth threshold, the terminal 1 and the terminal 2 are considered to belong to the same terminal cluster.

The distance between the terminal 1 and the terminal 2 can be determined according to the position information of the two terminals, that is, calculated according to the longitude and latitude of the two terminals.

As can be seen from fig. 6 and 7, the interference management module fully excavates the position distribution characteristics and regularity of each terminal in a longer time range through a preset algorithm based on the position information of each terminal in the target terminal cluster in each unit time period in the preset historical time, and divides the terminals with similar characteristics into the same terminal cluster, so that each terminal in the same terminal cluster is located in the same geographical area, the signal strength of each received beam is similar to the interference condition between beams, and further, the target beam to be accessed can be selected by using the terminal cluster as a unit, and the number of beams accessed by the terminals in the preset area is reduced by controlling each terminal in the same terminal cluster to access the target beam, thereby improving the interference suppression effect between beams, and realizing the interference management using the terminal cluster as a unit.

In one embodiment, the target beam measurement information further comprises: the beam frequency. In the above S402, the method for determining, by the interference management module, the target beam corresponding to the target terminal cluster according to the target beam measurement information specifically includes:

the interference management module determines at least one beam frequency included in the at least one target beam measurement information as at least one candidate frequency.

And the at least one target beam measurement information corresponds to at least one target terminal in the target terminal cluster one to one.

Specifically, the interference management module may determine a beam frequency included in the target beam measurement information as a candidate frequency.

The interference management module determines an average signal quality value for at least one candidate frequency based on the at least one target beam measurement information.

And the average signal quality value of at least one candidate frequency is the average value of the signal quality values of the candidate frequencies measured by at least one target terminal in the at least one target beam measurement information.

Specifically, the interference management module may determine an average signal quality value of each candidate frequency according to the target beam measurement information, that is, an average value of signal quality values of candidate frequencies measured by at least one target terminal in the target beam measurement information.

The interference management module determines a candidate frequency with a largest value as a target frequency from among the average signal quality values of the at least one candidate frequency, and determines at least one beam with at least one beam frequency as the target frequency as a candidate beam.

Specifically, the interference management module may determine the candidate frequency with the largest average signal quality value as the target frequency. Then, the interference management module may determine a beam of which beam frequency is the target frequency in the target beam measurement information as a candidate beam.

The interference management module determines an average signal strength value of the candidate beams and determines the candidate beam with the largest average signal strength value as the target beam.

The average signal strength value is an average value of candidate beam signal strength values measured by at least one target terminal in the at least one target beam measurement information. Or, if the candidate beam is the strongest beam of one target terminal in the target terminal cluster, determining one target terminal as the associated terminal corresponding to the candidate beam, and determining the candidate beam with the largest ratio of the number of the associated terminals to the total number of terminals included in the target terminal cluster as the target beam. The strongest beam is the beam with the maximum beam signal strength value measured by the target terminal.

In an implementation manner, when determining a target beam corresponding to a target terminal cluster, the interference management module may determine an average signal strength value of each candidate beam, that is, an average value of candidate beam signal strength values measured by at least one target terminal in the target beam measurement information.

Next, the interference management module may determine the candidate beam with the largest average signal strength value as the target beam.

In another implementation manner, when the interference management module may determine a target beam corresponding to a target terminal cluster, the interference management module may determine a weight of each candidate beam.

Wherein, the weight of the candidate beam is defined as the ratio of the number of the associated terminals of the candidate beam to the total number of the terminals contained in the target terminal cluster.

Specifically, if the candidate beam is the strongest beam of a target terminal in the target terminal cluster, the interference management module may determine the target terminal as the associated terminal corresponding to the candidate beam. Then, the interference management module may determine a candidate beam having a largest ratio of the number of associated terminals to the total number of terminals included in the target terminal cluster as the target beam.

The strongest beam of each target terminal in the target terminal cluster can be determined according to the target beam measurement information.

Specifically, the target beam measurement information includes beam measurement information corresponding to at least one target terminal in the target terminal cluster, where the beam measurement information corresponding to each target terminal includes at least one beam identifier and a corresponding beam signal strength value, and the interference management module may determine the beam with the largest beam signal strength value as the strongest beam of the target terminal.

As can be seen from the above description, in the multi-beam coverage area, when a terminal accesses a beam, a target beam to be accessed is determined not only based on the signal strength measurement value of a single terminal, but also based on the beam signal strength and the signal quality measurement value of each terminal in the terminal cluster.

Specifically, the interference management module may determine a target frequency and a corresponding candidate beam based on a beam signal quality measurement value of each terminal in the target terminal cluster, and further determine a target beam to be accessed from the candidate beams based on a beam signal strength measurement value of each terminal in the target terminal cluster.

Therefore, the target beam has higher average signal quality and smaller interference. Meanwhile, the average signal intensity of the target wave beam is higher, so that the received signal quality of each terminal in the target terminal cluster is improved, and the network performance requirement of the terminal is met.

In an embodiment, in the above S501, the method for determining, by the interference management module, at least one downlink interference beam according to the target beam measurement information of each target terminal in the target terminal cluster specifically includes:

in the at least one target beam measurement information, if the beam frequency of each beam of the at least one beam is the same as the frequency of the target beam and the average signal strength value of each beam is greater than a preset first signal strength threshold value, the interference management module determines the at least one beam as at least one downlink interference beam.

Specifically, in the target beam measurement information, if the beam frequency of a certain beam is the same as the frequency of the target beam and the average signal strength value is greater than a preset first signal strength threshold value, the interference management module determines the beam as a downlink interference beam. Wherein, the average signal strength value is defined as the average value of candidate beam signal strength values measured by at least one target terminal in the target beam measurement information.

In an embodiment, in the above S501, the method for determining, by the interference management module, a target interference beam corresponding to the target terminal cluster according to the edge service load of each downlink interference beam specifically includes:

if the edge service load of one downlink disturbing beam is smaller than a preset load threshold value, the interference management module determines one downlink disturbing beam as a target disturbing beam. Specifically, if the edge service load of a certain downlink interference beam is smaller than a preset load threshold, the interference management module may determine the downlink interference beam as a target interference beam.

The edge traffic load is defined as the ratio of the number of edge terminals of the beam or the number of Physical Resource Blocks (PRBs) occupied by the edge terminals to the total number of available PRBs of the beam. An edge terminal is a terminal located within the edge coverage area of the beam.

Optionally, if a terminal accessing the beam measures that the signal strength value of the beam is smaller than a preset second signal strength threshold, the terminal is determined as an edge terminal of the beam.

In the application, the interference management module may determine a downlink interference beam causing interference to the target terminal cluster according to the beam measurement information of each terminal in the target terminal cluster, and determine a target interference beam to be adjusted according to the edge service load information of the beam.

As the coverage area of the target interfering beam shrinks after the beam is adjusted, the signal strength received by a part of the terminals in the coverage area at the edge of the beam decreases, and the network performance may be affected. According to the method and the device, the interference beam is determined to be the target interference beam to be adjusted by selecting the beam with smaller marginal service load, so that the number of the terminals affected in the beam adjustment process can be reduced, the interference on the target terminal cluster is reduced, meanwhile, the influence on the service performance of other terminals in the preset area is reduced, and the overall network performance of the preset area is guaranteed.
