Detailed Description
It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.
In a first embodiment of the network static beam adaptive adjustment method of the present application, referring to fig. 1, the network static beam adaptive adjustment method includes:
step S10, determining initial beam parameters of static beams corresponding to the MIMO antenna;
step S20, acquiring power sharing performance indexes of the static wave beams corresponding to all cells, and determining a first cell with a power sharing record and a second cell with a power sharing record;
step S30, increasing the horizontal beam width in the initial beam parameter of the first cell to obtain a first horizontal beam width, and decreasing the horizontal beam width in the initial beam parameter of the second cell to obtain a second horizontal beam width;
and step S40, accessing the user terminal based on the first horizontal beam width and the second horizontal beam width.
The method comprises the following specific steps:
step S10, determining initial beam parameters of static beams corresponding to the MIMO antenna;
in this embodiment, it should be noted that the network static beam adaptive adjustment method may be applied to a network static beam adaptive adjustment system, where the network static beam adaptive adjustment system is subordinate to a network static beam adaptive adjustment device.
In this embodiment, the application scenario for which may be:
first, the cells corresponding to static beams of Massive MIMO sectors in the existing FDD network generally adopt fixed beam widths and normal direction angles, and face users with uneven distribution, the cell load corresponding to the static beams is often unbalanced, some cells have high load, and some cells have low load.
For example, a certain Massive MIMO sector corresponds to a cell, and its PRB (physical resource block) utilization rate is more than 30% different from that of cells corresponding to other beams.
Secondly, the cell corresponding to the static beam of the Massive MIMO sector of the existing FDD network does not consider the service applied by the user, and the throughput rate balance of the corresponding cell cannot be guaranteed.
In this embodiment, in a Massive MIMO scenario during an FDD LTE to FDD NR evolution process, based on statistics of power sharing performance (associated with user distribution) between cells corresponding to Massive MIMO static beams, adaptive adjustment is performed on beam width and normal direction angle of the Massive MIMO static beams, so that cell load balancing can be ensured, and power sharing performance is associated with cell user traffic, so that balancing of throughput rates of corresponding cells can be ensured.
It should be noted that Massive MIMO is an effective means for increasing system capacity, that is, an LTE-FDD network provides the same bandwidth for uplink and downlink services, and the uplink and downlink of data services occupy bandwidths of about 1. In order to solve the downlink congestion situation of the LTE FDD network, the LTE FDD gradually evolves to the NR FDD, and in the evolution process, the FDD network gradually evolves from the current 2T2R (2 Transmission-2receive,2 transmit-2 receive) to 4T4R (4 Transmission-4receive,4 transmit-4 receive), 8T8R (8 Transmission-8receive,8 transmit-8 receive) so that the Massive MIMO (32 Transmission-32receive,32 transmit-32 receive) evolves, and as the number of antenna arrays is increased, the narrower the generated beam is, better isolation and interference control can be achieved, and therefore, the narrow beam formed based on the Massive MIMO beam forming can obtain multiplexing gains of various resources in the same geographic area.
Thus, in this embodiment, a Massive MIMO sector scene is converted into a Massive MIMO beam scene.
In this embodiment, it should be noted that the Massive MIMO beamforming of the FDD network includes two ways:
first, dynamic Dedicated Beam mode (DDB);
specifically, user-level beam-based space division multiplexing is implemented in a Massive MIMO cell, so that multi-user space division multiplexing is achieved, that is, at the same scheduling time, a plurality of users distributed at different positions are orthogonally paired to share the same RB (Resource Block, minimum physical Resource unit) Resource, so that space division multiplexing is achieved, and the capacity of the whole cell is improved.
Second, static Shared Beam (SSB);
specifically, the static beam sharing is to control the soft splitting of the Massive MIMO sector into 4 cells (that is, by means of software control, static 4 beams are generated based on the Massive MIMO sector), so as to implement simultaneous scheduling of different cells at the same scheduling time, implement space division multiplexing, and achieve the purpose of increasing the capacity of the whole cell.
At present, adaptive adjustment of network static beams is applicable to a static beam scene of Massive MIMO, in the static beam scene of Massive MIMO, static 4 beams are generated through software control, a beam schematic is shown in fig. 4, and in the static beam scene of Massive MIMO in an FDD mode, the following two settings are generally adopted:
firstly, using fixed Beam width and normal direction angle, that is, in a static Beam scene of Massive MIMO in FDD mode, generating 4 static beams through software control, similarly splitting into 4 cells, as shown in fig. 4, defining a normal for each Beam, which is Beam 1, beam 2, beam 3, and Beam 4, and defining the normal of the Beam as: n1, n2, n3, n4, and the corresponding normal angles are: -44 °, -15 °,15 °,44 °. It should be noted that the positive MIMO static beam normal direction angle (normal angle) is a positive number deviating clockwise from the normal, or a negative number deviating counterclockwise from the normal, and the normal angle ranges from-60 ° to 60 °.
In addition, the angle of the normal between the static beams must be larger than 24 ° to control the overlapping coverage, and the beam width of each cell can be adjusted according to the coverage requirement.
In the present embodiment, the beam widths supported by the FDD mode Massive MIMO static beam scenario are 15 °,25 °,45 °,65 °, and 90 °. Since the existing FDD mode is based on a Massive MIMO sector, and the beam width of an antenna before the replacement of the Massive MIMO sector is 65 ° (also referred to as an antenna horizontal half-power angle), after the replacement of the Massive MIMO sector with the Massive MIMO antenna (since the more antenna arrays, the narrower the beam that can be generated, the better isolation and interference control can be achieved), the beam width of the whole sector is changed from 65 ° to 90 °, that is, the beam widths of 4 static beams in the sector are 25 °,25 °,25 °,25 °, as shown in fig. 5.
The beam width and the horizontal direction angle of each static beam may be adjusted, and it should be noted that, during adjustment, the overall coverage range of the Massive MIMO static beam needs to meet the overall coverage requirement of the original sector, and the normal direction coverage gain of each beam of the Massive MIMO static beam is maximized, and the normal of the static beam should target UE (user equipment) as much as possible, so that the UE obtains the best Signal-to-Interference plus Noise Ratio (SINR), obtains the highest possible modulation mode, and finally obtains the highest throughput rate.
In this embodiment, the physical antenna AAU unit of the Massive MIMO sector may be integrally adjusted, and the horizontal direction angle of each static beam is changed after the adjustment (that is, the beam width and the horizontal direction angle of each static beam may be adjusted to adapt to UE distribution and traffic distribution of the entire sector in the Massive MIMO scene).
Secondly, in this embodiment, the beam bandwidth and the normal horizontal direction angle of the static beam may also be calculated according to the number of users accessing each static beam, where the static beams accessing more users use a larger beam bandwidth, and correspondingly, the static beams accessing less users use a smaller beam bandwidth (the amount of data calculation is large).
In this embodiment, except that a fixed beam width and a normal direction angle are adopted, and an AAU unit of a physical antenna of a Massive MIMO sector is integrally adjusted, or a beam bandwidth and a normal horizontal direction angle of a static beam are calculated based on the number of users accessing each static beam, various electrical performance indexes (power sharing performance indexes) supported by the Massive MIMO antenna are collected, and load balancing is further achieved based on the power sharing performance indexes.
In this embodiment, as a whole, the load balancing based on the power sharing performance index may be implemented in three progressive manners, which are specifically as follows:
firstly, adjusting the horizontal beam width through a power sharing performance index so as to realize load balance;
secondly, adjusting the horizontal beam width, and if the load is unbalanced, adjusting the normal direction angle;
thirdly, after the normal direction angle is adjusted, lobe direction is also adjusted.
During the adjustment, the distributed power can also be adjusted synchronously.
In the adjusting process, parameters such as horizontal beam width and the like are adjusted based on the busy state of the traffic.
In this embodiment, first, an initial beam parameter of a static beam corresponding to the MIMO antenna is determined, where the initial beam parameter may specifically be a parameter such as an initial horizontal beam width (i.e., a horizontal half-power angle), an initial normal direction angle, an initial electrical downtilt angle, an initial AAU overall power, and each initially allocated power;
that is, in this embodiment, first, various electrical performance indexes supported by the Massive MIMO antenna are collected, including parameters such as (static beam) horizontal beam width (i.e., horizontal half-power angle), (static beam) normal direction angle, electrical downtilt, AAU overall power, and power allocated to each (static beam);
in the present embodiment, the setting of the horizontal beam width and the vertical beam width may be as shown in table 1, and the setting of the electrical downtilt angle may be as shown in table 2. Based on table 1, table 2 may initially set the Massive MIMO horizontal beam width to SCENARIO _4 in table 1, that is, the horizontal beam width is 25 °, and the corresponding vertical beam width is 8 °.

Wherein, the Massive MIMO sector is normal direction angle 0 °, its 4 static beams are Beam 1, beam 2, beam 3, beam 4, respectively defining the Beam normal as: n1, n2, n3, n4, and the corresponding normal angles are: -44 °, -15 °,15 °,44 °.
In this embodiment, the overall power of the Massive MIMO antenna AAU unit and the power allocated to each static beam are also collected.
If the overall power of the Massive MIMO antenna AAU unit is: 160w, the power initially allocated for 4 static beams is: 40W, 40W and 40W;
step S20, acquiring power sharing performance indexes of the static wave beams corresponding to all cells, and determining a first cell with a power sharing record and a second cell with a power sharing record;
in this embodiment, the power sharing performance index of each cell corresponding to the static beam is collected, and the first cell having the power sharing record and the second cell having the power sharing record are determined.
The power sharing of the cell corresponding to the static beam refers to: under the condition that the set condition is met, the power is shared out of the cell (on the basis that the self service requirement is met), the residual power is shared to the power with higher load to be shared into the cell, the power is shared into the cell to improve the carrier-to-interference ratio, a higher modulation mode is obtained, and the wireless throughput rate is improved.
Wherein the step of determining a first cell having a power-sharing out record and a second cell having a power-sharing in record comprises:
step a1, if the fact that the downlink instantaneous PRB utilization rate of a cell network is lower than a first utilization rate threshold value is detected, a corresponding cell is a first cell with a power sharing record;
and a2, if the fact that the downlink instantaneous PRB utilization rate of the cell network is higher than a second utilization rate threshold value is detected, the corresponding cell is a first cell with a power sharing record.
Specifically, the setting conditions for power sharing out of the cell are as follows: the utilization rate of the LTE downlink instantaneous PRB (PHYSICAL RESOURCE BLOCK) is lower than a threshold T1 (a first utilization threshold), where the number of TTIs (l.pwrshare.pwrrout.tti.num) shared by the cell power refers to the number of TTIs actually used by the cell to share the power. The setting conditions of power sharing into the cell are as follows: the LTE downlink instantaneous PRB utilization exceeds a threshold T2 (second utilization threshold), and the number of TTIs for cell power sharing (l.pwrshare.pwrlin.tti.num) refers to the number of TTIs for which the cell actually uses the shared power. When determining the shared Cell, in addition to the LTE-based downlink instantaneous PRB utilization, the demodulation method and the modulation method used in the downlink may be referred to at the same time, so that the LTE downlink instantaneous PRB utilization exceeds T2, and a Cell whose user ratio of the downlink uses CRS demodulation (Cell Reference Signal) and QPSK modulation (Quadrature Phase Shift Keying modulation) exceeds a threshold T3 (third utilization threshold) is set as the power-shared Cell.
In this embodiment, the record shared by the cell power is used to represent that the cell has fewer access users and low load; the record of cell power sharing represents that the cell has more access users and high load.
Step S30, increasing the horizontal beam width in the initial beam parameter of the first cell to obtain a first horizontal beam width, and decreasing the horizontal beam width in the initial beam parameter of the second cell to obtain a second horizontal beam width;
in this embodiment, the horizontal beam width of the corresponding cell is shared by increasing the power, more users are correspondingly accessed, the horizontal beam width of the corresponding cell is shared by decreasing the power, and the users are correspondingly accessed.
Referring to table 1, increasing the horizontal beam width in the first cell initial beam parameter may be: the horizontal beam width of the static beam of the corresponding cell is shared by the power and is adjusted to be SCENARIO _3 by SCENARIO _ 4;
namely, the horizontal beam width of the cell is adjusted to be 25-45 degrees, and the vertical beam width is kept unchanged and is still 8 degrees;
referring to table 1, the reducing the horizontal beam width in the initial beam parameter of the second cell may specifically be: sharing power into the horizontal beam width of the static beam of the corresponding cell, and adjusting the horizontal beam width from SCENARIO _4 to SCENARIO _9;
namely, adjusting the horizontal beam width of the cell to 25-15 degrees, and adjusting the vertical beam width to 8-17 degrees;
and step S40, accessing the user terminal based on the first horizontal beam width and the second horizontal beam width.
And accessing the user terminal (UE) after the first horizontal beam width and the second horizontal beam width are obtained.
In this embodiment, the horizontal beam width of the corresponding cell is shared by increasing the power, and more users are accessed; the horizontal beam width of power sharing in the corresponding cell is reduced, and the access users are reduced; therefore, the main lobe of the static beam points to more users, and the users obtain better carrier-to-interference ratio.
Compared with the prior art that the cell load is difficult to accurately balance, in the method, after the initial beam parameters of the static beam corresponding to the MIMO antenna are determined, the power sharing performance indexes of the static beam corresponding to each cell are collected, and a first cell with a power sharing record and a second cell with a power sharing record are determined; increasing the horizontal beam width in the initial beam parameter of the first cell to obtain a first horizontal beam width, and decreasing the horizontal beam width in the initial beam parameter of the second cell to obtain a second horizontal beam width; and accessing the user terminal based on the first horizontal beam width and the second horizontal beam width. That is, in the present application, power sharing performance between cells corresponding to different static beams is counted, and beam width adjustment is performed on the static beams in a Massive MIMO scene, that is, the horizontal beam width corresponding to a first cell with shared power (which is difficult to meet a large amount of access requirements) is increased, so as to access users more; the horizontal beam width of the static beam corresponding to the second cell with shared power (power excess) is reduced, so that users are accessed less, namely, the cells with different access requirements are subjected to balanced load.
Further, based on the first embodiment of the present application, another embodiment of the present application is provided, in which after the step based on the first horizontal beam width and the first horizontal beam width, the method further includes:
step S50, determining the number of times of sharing the power of the first cell;
step S60, if the shared frequency exceeds a preset frequency threshold, adjusting the normal direction angle in the initial beam parameter of the first cell to the second cell, and accessing the user terminal.
In this embodiment, the number of times of power sharing of the first cell is determined, and if the number of times of power sharing exceeds a preset number threshold, the normal direction angle in the initial beam parameter of the first cell is adjusted to the second cell and the user terminal is accessed, that is, if the horizontal beam width of the static beam of the power sharing corresponding to the cell C1 is increased and the number of times of power sharing still exceeds a T0 threshold (preset number threshold), the normal direction angle of the static beam corresponding to the cell is adjusted to turn to the power sharing access cell C2, and the normal direction angle included angle between the static beam corresponding to the cell C1 and the cell C2 is reduced; specifically, as shown in fig. 6, in the established rectangular coordinate system, the normal corresponding to the cell C1 is: n1, the normal corresponding to the cell C2 is: n2; after the adjustment corresponding to the normal line, cell C1 becomes n11, and n1 is deviated in the n2 direction by a step value S1, which is set to 5 °, that is: adjusting n1 to n11, and the direction angle is from-44 degrees to-39 degrees.
In this embodiment, the normal direction angle in the initial beam parameter of the first cell is adjusted to the second cell, and the ue is accessed, so that the first cell with shared power can access multiple users.
After the step of steering the normal direction angle adjustment in the initial beam parameter of the first cell to the second cell, the method comprises:
and step S70, adjusting the normal direction angle in the initial beam parameter of the second cell to the reverse direction of the first cell, ensuring that the included angle of the normal direction angles corresponding to the first cell and the second cell is greater than a preset normal angle, and accessing the user terminal.
In this embodiment, the normal direction angle included angle of the static beam corresponding to the first cell and the second cell is reduced, and if the normal direction angle included angle corresponding to the first cell and the second cell is smaller than 24 °, the normal direction angle of the second cell needs to be correspondingly adjusted, and the direction is continuously reversed to the direction of the first cell, that is, the normal direction angle in the initial beam parameter of the second cell is adjusted to the direction of the first cell, so that it is ensured that the normal direction angle included angle corresponding to the first cell and the second cell is larger than a preset normal angle, and the user terminal is accessed.
In this embodiment, the number of times of power sharing of the first cell is determined; and if the shared times exceed a preset time threshold, adjusting the normal direction angle in the initial beam parameter of the first cell to the second cell, and accessing the user terminal. In this embodiment, the first cell multi-access user is made power-shared (difficult to meet large access demands).
Further, based on the first embodiment and the second embodiment in this application, another embodiment of this application is provided, in which after the step of determining the first cell having the power-sharing-out record and the second cell having the power-sharing-in record, the method further includes:
step A1, reducing a first allocated power in the first cell initial beam parameter, and increasing a second allocated power in the second cell initial beam parameter;
and step A2, accessing the user terminal based on the first distributed power and the second distributed power.
