All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.
In the description of the present specification, a description referring to terms "one embodiment," "some embodiments," "examples," "specific examples," or "some examples," etc., means that a particular feature, structure, material, or characteristic described in connection with the embodiment or example is included in at least one embodiment or example of the embodiments of the present application.

Furthermore, the different embodiments or examples described in this specification and the features of the different embodiments or examples may be combined and combined by those skilled in the art without contradiction.
The following describes in detail, with reference to the attached drawings, a specific embodiment and an application scenario thereof, a method and an apparatus for transmitting a broadcast beam provided in the embodiments of the present application.

S110, acquiring a service beam transmitted by a base station within a preset time length, and determining a transmission parameter vector set of the service beam;
s120, carrying out preset processing on the sending parameter vector set to determine a reference beam cluster;
s130, transmitting broadcast beams according to the reference beam clusters.
The execution body of the broadcast beam transmission method in the embodiment of the present application may be an electronic device, a component in the electronic device, an integrated circuit, or a chip.
The electronic device may be a mobile electronic device or a non-mobile electronic device. By way of example, the mobile electronic device may be a cell phone, tablet computer, notebook computer, palm computer, vehicle-mounted electronic device, wearable device, ultra-mobile personal computer (ultra-mobile personal computer, UMPC), netbook or personal digital assistant (personal digital assistant, PDA), etc., and the non-mobile electronic device may be a server, network attached storage (Network Attached Storage, NAS), personal computer (personal computer, PC), television (TV), teller machine or self-service machine, etc., and the embodiments of the present application are not limited in particular.
The following describes in detail the technical solution of the present application by taking a base station (computer) as an example to execute the method for transmitting a broadcast beam provided in the embodiment of the present application.
Firstly, the base station acquires the number of service beams and specific information of the service beams transmitted by the base station within a preset time length, and establishes a transmission parameter vector set.
The preset time length can be set (customized) according to actual needs or determined according to the scene where the base station is located.
For example, according to the scene served by the base station, the principle of determining the preset time length may be that "the scene with strong personnel mobility has a small value and the scene with weak personnel mobility has a large value". Different scene classifications may correspond to different preset lengths of time, respectively. For example: a business area may take 3 seconds, a residential area may take 4 seconds, etc. The preset time length can be empirically determined and set to a default value according to a specific scenario.
The set of transmission parameter vectors comprises transmission parameter vectors for a plurality of traffic beams, each transmission parameter vector comprising transmission parameters for a traffic beam. In one embodiment, the transmission parameters include at least the steering angle of the traffic beam.
After the set of the sending parameter vectors of the service beam is established, the base station can perform preset processing on the sending parameter vectors to obtain a reference beam cluster.
The reference beam cluster represents the transmission characteristics of the service beam, such as the direction angle of the service wave speed.
After the reference wave velocity cluster is acquired, the base station can correspondingly transmit the broadcast wave beam based on the reference wave beam cluster.
After the service beam establishes connection for the user, the gNB dynamically performs beam forming on the user according to the actual distribution situation of the user. In service beamforming, the beam is performed by adopting a dynamic beamforming mode. Depending on the user behavior, the size of the user is larger in the direction of the relative convergence of the traffic beams compared to the direction of the fewer or no traffic beams. Thus, the transmission of the traffic beam can reflect the nature of the user aggregation.
Therefore, according to the method for transmitting the broadcast beam, the reference beam cluster is obtained by processing the transmission parameters of the service beam, and the transmission of the broadcast beam is determined according to the reference beam cluster, so that the broadcast beam can be transmitted by referring to the transmission characteristics of the service beam, the broadcast beam can precisely cover the area where users gather, the null transmission and the invalid transmission of the broadcast beam are avoided, the energy consumption of the 5G base station is obviously saved, and the coverage area and the intensity of the broadcast beam to the area where users are dense are effectively increased.
In one embodiment, S120 may include:
S1201, dividing a transmission parameter vector set according to coverage angle ranges of cells to determine transmission parameter vector sub-sets of all coverage angle sub-ranges;
s1202, determining the number of the reference beam clusters and each reference beam cluster according to the transmission parameter vector sub-sets of each coverage angle sub-range.
According to the broadcast beam transmitting method, the number of the reference beam clusters and each reference beam cluster are determined by dividing the transmitting parameter vector set according to the coverage angle sub-range of the cell, so that the acquisition of the reference beam clusters is very accurate.
In one embodiment, S1201 may include:
s12011, determining the maximum number of reference beam clusters according to the frequency of a New Radio (NR) system;
s12012, determining each coverage angle sub-range according to the coverage angle range of the cell and the maximum number;
s12013, determining a transmission parameter vector sub-set of each coverage angle sub-range according to each coverage angle sub-range and the direction angle of the service beam.
It should be noted that, there is a correspondence between the maximum number of reference beam clusters and the frequency of the NR system. For example, when the NR system employs SUB 2.4GHz, the maximum number of reference beam clusters is 4; when the NR system adopts 2.4-6 GHz, the maximum number of the reference beam clusters is 8; the maximum number of reference beam clusters is 64 when the NR system employs above 6 GHz.
After determining the maximum number of reference beam clusters, the coverage angle range of the cell can be precisely divided into a plurality of coverage angle sub-ranges.
And then, judging which coverage angle sub-range the sending parameter vector belongs to according to the direction angle of the service beam. All the transmission parameter vectors in the coverage angle sub-range can form a transmission parameter vector sub-set of the coverage angle sub-range.
According to the broadcast beam transmitting method, the coverage angle sub-ranges are determined according to the coverage angle ranges of the cells and the maximum number of the reference beam clusters, so that the coverage angle sub-ranges can be accurately divided. And the transmission parameter vector sub-sets of all coverage angle sub-ranges are determined through the direction angles of the service beams, and the transmission parameter vectors in the transmission parameter vector sets can be precisely attributed to the corresponding coverage angle sub-ranges.
In one embodiment, determining the number of reference beam clusters in S1202 may include:
determining the number of reference beam clusters according to the number of transmission parameter vectors in the transmission parameter vector sub-sets of each coverage angle sub-range and the service beam scale number;
The service beam scale number is determined according to the preset time length, the service beam scheduling period of the NR system and the maximum dynamic beam of the NR system.
Specifically, whether the coverage angle sub-range has meaning may be determined by determining a ratio of the number of transmission parameter vectors to the number of service beam sizes in each coverage angle sub-range.
For example, when the above-mentioned duty ratio is extremely small, it is explained that there are few service beams directed to the area covered by the coverage angle sub-range, and there are relatively few users reflecting the area. Therefore, determining a reference beam cluster for this area is not significant for saving power consumption of the 5G base station.
According to the method for transmitting the broadcast beam, the number of the reference beam clusters is determined according to the number of the transmission parameter vectors in the coverage angle sub-ranges, so that the number of the reference beam clusters can be ensured to be reasonable for saving the energy consumption of the 5G base station, the energy consumption of the 5G base station is effectively saved, and the coverage range and the strength of the broadcast beam to a user-dense area are effectively increased.
In one embodiment, determining the reference beam cluster in S1202 may include:
s12021, normalizing the transmission parameter vector in the transmission parameter vector sub-set;
S12022, clustering the standardized transmission parameter vectors to obtain clustered transmission parameter vectors;
s12023, the clustered transmission parameter vectors are subjected to de-normalization to obtain a reference beam cluster.
According to the broadcast beam transmitting method, the transmission parameter vector is standardized, the standardized transmission parameter vector is clustered, and the clustered transmission parameter vector is de-standardized to determine the reference beam cluster, so that the transmission characteristics of the service beam cluster can be accurately summarized, the finally obtained reference beam cluster can inherit the transmission characteristics of the service beam cluster, and an effective basis is provided for the subsequent transmission of the broadcast beam cluster.
The following describes in detail a broadcast beam transmitting method provided in the embodiment of the present application with reference to a specific embodiment.
In this embodiment, the transmission parameter vector of the service beam is a quaternary vector
Wherein A is the direction angle of the service beam, and the unit is degree; d is the downward inclination angle of the service beam, and the unit is degree; h is the horizontal lobe width of the service beam in degrees; v is the vertical lobe width of the traffic beam in degrees. The single shaped beam of the broadcast channel and the traffic channel can be formed by Vector representation is performed.
Within a preset time length delta t, the stored transmission parameter vector of each service beamTransmission parameter vector set C constituting service beam PDSCH Wherein, the method comprises the steps of, wherein,
in this embodiment, the frequency of the NR system is 2.4-6 GHz, so the maximum number of reference beam clusters, K, is 8.
Setting coverage angle of cell as theta cell Its coverage angle range is theta start ~θ end . Dividing the coverage angle range of the cell into 8 coverage angle sub-ranges S, each coverage angle sub-range S being theta cell /8, nth coverage angle subrange S n Covering an angle range of (theta) start +n*θ cell /8)~(θ start +n*θ cell /8+θ cell /8),n∈(0,7)。
According to the set of transmission parameter vectors C PDSCH All of the transmission parameter vectors in (a)First element A of i (i.e. direction angle) for the transmission parameter vector +.>And classifying coverage angle sub-ranges.
For example, the ith transmission parameter vectorFirst element A of i =10°, a first coverage angle subrange S 1 In the range of (0 °,15 °), due to a i =10° belonging to the range (0 °,15 °), whereby the ith transmission parameter vector +.>Is assigned to a first coverage angle subrange S 1 A first coverage angle subrange S 1 Is>The statistical value is increased by 1, and the number N of the transmission parameter vectors of each coverage angle sub-range is calculated by analogy n
The maximum number K of reference beam clusters is as follows:
wherein N is beam Is the number of service beam scales. The downlink beam of NR system is formed by dynamic beam forming technology, the current dynamic beam quantity is 32 beams, and 32 CSI-RS are adopted. The dynamic beam forming of the service beam adopts a scheduling period TTI for forming.
Setting the service beam scheduling period of NR system as T period The service beam size number is
The alpha value is a parameter quantity excluding singular beams, and can be set by self, for example, 0.01. The meaning is that the number of beams in a coverage angle sub-range is equal to that in the transmission parameter vector set C PDSCH If the duty cycle is too low, it is classified as a singular beam.
The step of determining each reference beam cluster comprises:
the first step: for a set of transmit parameter vectorsAll transmit parameter vectors of (a)The normalization operation is performed using a zero-mean (z-score) standard algorithm.
After the z-score normalization operation, the data met a standard normal distribution (mean 0, variance 1). Specific standardized formulas are as follows:
for the set of transmission parameter vectors C PDSCH Normalized for all a (direction angle) elements:
A' i is A i Is used to determine the value of the normalized value of (c),to be the instituteThere is a mean value of the a (direction angle) elements, σ is the standard deviation of all a elements.
After the other D (declination angle), H (horizontal lobe width) and V (vertical lobe width) are normalized in sequence, a normalized parameter vector set is generated:
and a second step of: according to the maximum number K of reference beam clusters, at S n Not equal to 0, and randomly selecting one transmission parameter vector in the range from K coverage angle sub-ranges of n epsilon (0, 7)For the centroids of the group of classified beam clusters, K random beam cluster centroids are generated in total to B i Indicating i e (1, K).
And a third step of: calculate C' PDSCH Each of the transmission parameter vectors except the centroid is assigned to the centroid beam cluster closest to the geometric distance of the transmission parameter vector from the K centroids.
With this algorithm C' PDSCH Can be categorized by the K centroids.
Now take M' 1 By way of example, the equation is referred to as follows:
M' 1 =[A' 1 、D' 1 、H' 1 、V' 1 ]
wherein the mass centers of the K wave beam clusters are respectively B 1 、B 2 ...B K
Calculate M' 1 Distance B 1 Geometric distance d (M' 1 ,B 1 ):
In this way M 'is calculated in succession' 1 Geometric distance d (M 'from other centroids' 1 ,B 2 )…d(M' 1 ,B K ) Judging M' 1 The minimum geometrical distance from these several centroids. Suppose d (M' 1 ,B 2 ) Is M' 1 The shortest distance from each centroid will be M' 1 And centroid B 1 Is classified into a beam cluster, and the same is true of C' PDSCH Each of the transmit parameter vectors may find its corresponding beam cluster.
K beam clusters are thus obtained, each beam cluster being made up of a plurality of transmission parameter vectors.
Fourth step: the centroids of the K beam clusters are recalculated, the transmission parameter vector in each beam cluster is averaged, and the averaged value is calculated as a new cluster center, for example:
B 1 =average(M' K1 ),M' K1 for all transmit parameter vectors contained in the first beam cluster.
Assuming that the first cluster of beams contains K1 quad-vectors in total, then a new centroid B 1 The specific calculation formula of (2) is as follows:
thereby generating a new centroid B of the first beam cluster 1 The centroid is recalculated for the remaining K-1 beam clusters according to this algorithm as the new centroid for the remaining K-1 beam clusters.
After the centroids of the K beams are updated, the iteration number L is increased by 1.
Fifth step: and judging whether the iteration times L are larger than or equal to the set maximum iteration times T. If not, continuing to judge in the sixth step; if yes, terminating the iteration and outputting the mass centers B of the K beam clusters i ,i∈(0,K)。
Sixth step: and judging whether the updated geometric distance d between the centroid of the beam cluster and the old centroid reaches a convergence parameter delta, and if so, ending iteration.
Seventh step: repeating the third step to the sixth step until the iteration is finished.
Further, the de-normalizing the clustered transmission parameter vectors to obtain a reference beam cluster includes:
outputting the mass centers of the K wave beam clusters, which are respectively B 1 、B 2 ...B K Since the beam cluster is still a standardized beam cluster, the transmission parameter vector values of K beams can be output according to a standardized formula.
Examples are:
the normalized centroid of the first beam cluster is determined asAccording to the standardized formula->The method can be as follows:
and then outputs the actual reference beam cluster B 1 All K non-normalized reference beam clusters B can be obtained in the same way 2 ...B K
And finally, the base station can send the broadcast beam according to the finally obtained reference beam cluster. For example, the base station may transmit a broadcast beam within 5ms after a preset length of time has elapsed.
It should be noted that the base station may control the direction angle, the downtilt angle, the horizontal lobe width, and the vertical lobe width of the broadcast beam at the time of transmission according to the elements of the vector in the reference wave velocity cluster, such as the direction angle, the downtilt angle, the horizontal lobe width, and the vertical lobe width.
And, the base station may also transmit broadcast beams according to the number of reference beam clusters. For example, when the number of reference beam clusters is 5, the base station may transmit broadcast beams only to coverage areas corresponding to the 5 reference beam clusters.
In summary, the method for transmitting the broadcast beam provided by the embodiment of the application breaks through the polling transmission mode of the broadcast beam in the fixed time and fixed beam in the prior art, innovatively proposes to dynamically form the broadcast beam forming according to the distribution situation of users, on one hand, the reduction of the energy consumption of the 5G base station is realized, on the other hand, the accurate coverage of the broadcast signal is realized, and the efficiency is improved.
On the other hand, the method for transmitting the broadcast beam innovatively carries out the beam forming process of the broadcast beam and the service beam, realizes linkage in an artificial intelligence mode, carries out advantage complementation on the two beam forming modes, and realizes the real-sense beam forming of the broadcast beam.
