An embodiment of the present invention provides a beam configuration method, referring to fig. 2, fig. 2 is a schematic flow chart of a first embodiment of a beam configuration method of the present invention.
In this embodiment, the beam configuration method includes the following steps:
Step S10: first beam performance information corresponding to each broadcast beam and second beam performance information corresponding to each sounding reference signal in the time division duplex network are counted.
The execution body of the method of the present embodiment may be a device having functions such as data processing, network communication, and program running, for example: the cloud server, the control computer, or the like may be any other device capable of realizing the same or similar functions, and this embodiment is not particularly limited.
It can be understood that the New air interface system (NR) adopts a beamforming technology, according to the weight policy difference adopted in beamforming, the NR beams are divided into static beams and dynamic beams, when the static beams are beamformed, predefined weights are adopted, that is, fixed beams are formed in a cell, for example, the number, the width and the direction of the beams are determined, and then the optimal beams are selected for various channels and signals according to the information of cell coverage, user distribution, system load and the like.
The static beam is divided into a broadcast beam and a control beam, the broadcast beam is a typical static beam, the SS and the PBCH share one beam, the broadcast beam is simply called a broadcast beam, the broadcast beam is a cell grade beam, in order to enhance the coverage of a broadcast channel and a synchronous signal under a cell, the coverage of the cell and the user distribution are better matched, and the beams of various coverage scenes are required to be supported; the control beam corresponds to one beam of each type of control channel or signal respectively, and is generally called a control beam, and typical channels are: PUCCH, PDCCH, CSI-RS. When the beams corresponding to the control beams are a plurality of narrow beams, the UE measures the narrow beams, gNodeB maintains a beam set aiming at the result reported by the UE measurement, selects the optimal beam for each channel and signal to use, and selects the beam with the largest RSRP for the CSI-RS to use through SRS beam measurement.
NR cells synchronize and broadcast channels share one broadcast beam (SSB), which is a cell-level beam, gNodeB periodically transmits SSB beams according to SSB periods (MS 5, MS10, MS20, MS40, MS80, MS160, units: milliseconds), broadcast synchronization messages and system messages, and in the conventional art, when an NR cell generally uses a plurality of SSB beams, SSB beams of one direction are transmitted at each time in the time domain dimension, SSB beams of different directions are transmitted at different times, and coverage of the entire cell is completed, as shown in fig. 3.
At present, an engineer can select one of weight configuration according to the actual coverage scene type to finish weight optimization according to an activated antenna unit fixed weight beam scheme supported by a time division duplex network as shown in a table 1.
Table 1 AAU antenna fixed weight beam scheme
However, due to possible differences in the actual user distribution inside the cell, the coverage rate of the broadcast beam in the beam configuration mode using Default0 is low, especially in the time division duplex network (Time Division Duplexing, TDD) using active antenna units (ACTIVE ANTENNA Unit, AAU) of the Massive MIMO multi-channel antenna, there are cases where the user distribution is unbalanced under the coverage of the base station, or the user dense area changes with time due to mobility.
In order to solve the above problem, in this embodiment, by counting beam performance information of each broadcast beam and second beam performance information of a sounding reference signal in a time division duplex network, performing first-order user position positioning in a target area with the first beam performance information, performing second-order user position positioning in the target area with the second beam performance information, so as to determine a user position in a certain time period, and finally performing parameter configuration on the broadcast beam by combining a user dense area obtained by two positioning under a change condition of user displacement in different time periods, so as to select an optimal beam for various channels and signals according to information such as cell coverage rate, user distribution, and the like, thereby improving coverage performance of the broadcast beam.
It is understood that a tdd network is a duplex mode of a communication system, that is, a communication mode in which reception and transmission are separated by a guaranteed time in a mobile communication system by using different time slots of the same frequency channel, that is, carrier.
Sounding REFERENCE SIGNAL (SRS), i.e. uplink Sounding or Sounding signals, the UE transmits the Sounding reference signals within the active BWP bandwidth, gNodeB receives and processes the SRS of the UE, and obtains corresponding interference signal to noise ratio (Signal to Interference plus Noise Ratio, SINR), RSRP (REFERENCE SIGNAL RECEIVED Power ), PMI (Precoding Matrix Indication), and so on.
In this embodiment, the first beam performance information includes: average user number and data throughput of a data link layer, wherein the data throughput comprises uplink data total throughput and downlink data total throughput; the second beam performance information includes: access user number and traffic throughput.
Further, in order to accurately count performance information of broadcast beams and sounding reference signals in the time division duplex network, the embodiment may further acquire relevant parameters of each broadcast beam and each sounding reference signal in the time division duplex network before counting performance information of a first beam corresponding to each broadcast beam and performance information of a second beam corresponding to each sounding reference signal in the time division duplex network, so as to control the activated antenna unit to output a beam meeting requirements.
Specifically, the relevant parameters of the broadcast beam include the horizontal half-power angle, azimuth angle and electronic downtilt angle of the antenna; and SSB beam numbering, SSB beam tilt angle, SSB beam azimuth angle, SSB beam horizontal width, SSB beam vertical width, etc., and the specific configuration strategies of the relevant parameters refer to table 2.
TABLE 2
In addition, the relevant parameters of the sounding reference signal include SRS slot period, SRS slot bias parameters, and the like.
Step S20: and positioning the user position of the target area according to the first beam performance information to obtain a first user dense area.
It should be understood that, positioning the target area according to the first beam performance information refers to performing first-order positioning on the target area in the horizontal direction to determine a user-dense area in the horizontal direction in the target area, and in this embodiment and the embodiments described below, the target area may be divided into a side wing area and a middle area in the horizontal direction, or into a left side area, a middle area, and a right side area, which is not limited in particular in this embodiment.
When judging the user dense area in the horizontal direction, the duty ratio of the user occupying the whole target area in each divided area can be calculated and determined, and if the user duty ratio or the data throughput duty ratio in a certain area is larger than a set threshold value, the area is judged to be the user dense area.
Step S30: and positioning the user position of the target area according to the second beam performance information to obtain a second user dense area.
It should be understood that, positioning the user position of the target area according to the second beam performance information refers to performing secondary positioning on the target area in the vertical direction to determine a user-dense area in the vertical direction in the target area, where the target area may be divided into four layers in the vertical direction in this embodiment and the embodiments described below, the user-dense area occupies at least two layers, and the target area has at most three user-dense areas in the vertical direction.
When judging the user dense area in the vertical direction, the duty ratio of the user occupying the whole target area in each divided area can be calculated, and if the beam data volume duty ratio in a certain area is larger than a set threshold value, the area is judged to be the user dense area.
Step S40: and carrying out beam parameter configuration on the broadcast beam according to the first user dense area and the second user dense area.
In this embodiment, the configuration of beam parameters for the broadcast beam is mainly based on the deployment mode and the deployment number of the broadcast beam in the user dense area.
According to the embodiment, the beam performance information of each broadcast beam and the second beam performance information of the sounding reference signal in the time division duplex network are counted, the first-order user position positioning is carried out in the target area by the first beam performance information, the second-order user position positioning is carried out in the target area by the second beam performance information, so that the user position in a certain time period is judged, the change condition of the user displacement in different time periods is finally combined with the user dense area obtained by two positioning to carry out parameter configuration on the broadcast beam, the optimal beam is selected for various channels and signals according to the information such as cell coverage rate, user distribution and the like, the coverage performance of the broadcast beam is improved, the technical problem that the coverage performance of the broadcast beam in a single area is insufficient in the prior art is avoided, and the coverage rate of the broadcast beam is improved.
Referring to fig. 4, fig. 4 is a flow chart of a second embodiment of a beam configuration method according to the present invention.
Based on the first embodiment, in this embodiment, the step S20 includes:
Step S201: and acquiring the target user number corresponding to the signal coverage area of each broadcast beam in the target area and the total user number of the target area.
It should be understood that the number of users in each area may be the number of users in each broadcast beam obtained by sampling each second, determining the UE beam direction based on the measurement of the sounding reference signal, determining the optimal broadcast beam to which the UE belongs, and averaging the UEs according to the optimal broadcast beam to which the UE belongs.
Since the target area is divided into the flanking area and the middle area, or the left area, the middle area and the right area, but since the horizontal deployment mode and the deployment number of the broadcast beams in the left area and the right area are the same, the embodiment can combine the left area and the right area to form the flanking area, and there may be a plurality of broadcast beams in one area, and the coverage areas of the broadcast beams may overlap, and the number of users of the coverage areas of the broadcast beams may be calculated separately, which may affect the accuracy of the final result, the embodiment can calculate the ratio of the total number of users of the divided areas to the total number of users of the target area, so as to determine whether the area is a dense area.
Step S202: and positioning the user position according to each target user number and the total user number to obtain a first user dense area.
In a specific implementation, when the user dense area is located by the number of users, 8 SSB beams are configured in a cell, and the numbers are ：SSB0+SSB1+SSB2+SSB3+SSB4+SSB5+SSB6+SSB7 from left to right in turn, which is an example, the user dense area can be determined based on the number of target users corresponding to the signal coverage area of each broadcast beam in the left area, the middle area and the right area in the target area, that is, the probability that the user dense area is located in the left azimuth of the cell:
Lleft_user_ssB＝(SSB0+SSB1+SSB2+SSB3)/∑SSBi
Lleft_user>T0
probability that the user dense area is located in the middle side direction of the cell:
Lcentre_user_SSB＝(SSB2+SSB3+SSB4+SSB5)/∑SSBi
Lcentre_user>T0
probability that the user dense area is located in the right-hand direction of the cell:
Lright_user_SSB＝(SSB4+SSB5+SSB6+SSB7)/∑SSBi
Lright_user>T0
Wherein, T0 may be 60%, or other values may be set.
Further, the step S20 further includes:
step S201': and calculating the total data throughput of the data link layer under the broadcast beam according to the uplink data total throughput and the downlink data total throughput of the data link layer.
Step S202': and positioning the user position according to the total data throughput to obtain a first user dense area.
It can be understood that, in this embodiment, besides determining the user dense area by the number of users in each area, the first-order user location positioning may also be performed by using the total throughput of the data of the downlink data layer of the broadcast beam, where the total throughput of the data of the downlink data layer of the broadcast beam is equal to the sum of the total throughput of the uplink data of the data layer of the downlink data layer of the broadcast beam and the total throughput of the downlink data of the data layer of the downlink data layer of the broadcast beam.
The uplink data total throughput of the data link layer can be based on sounding reference signal measurement, judging the beam direction of the UE, determining the optimal broadcast beam to which the UE belongs, counting uplink data received by the MAC layer of the UE, accumulating the correctly received TB size, and accumulating according to the optimal broadcast beam to be counted as a statistical result; the downlink data total throughput of the data link layer can be based on sounding reference signal measurement, judging the beam direction of the UE, determining the optimal broadcast beam to which the UE belongs, counting the downlink data sent by the MAC layer of the UE, accumulating the TB size of the received ACK, accumulating according to the total accumulated optimal broadcast beam to be used as a statistical result.
Further, the step S30 includes:
Step S301: and acquiring horizontal distribution information and vertical distribution information of each detection reference signal.
Step S302: and calculating the beam data volume ratio of the channel corresponding to each sounding reference signal according to the access user number, the service throughput, the horizontal distribution information and the vertical distribution information.
Step S303: and positioning the position of the target area for the second time according to the beam data volume ratio to obtain a second user dense area.
It should be noted that the horizontal distribution information refers to a horizontal angle and a beam horizontal distribution; the vertical distribution information refers to a vertical angle and vertical beam distribution, in this embodiment, a 64-channel activated antenna unit antenna is taken as an example for explanation, the 64-channel activated antenna unit antenna supports 32 beams, the base station can calculate the strongest beam number of the user according to uplink SRS measurement, and the position of each beam in space is fixed relative to the activated antenna unit, and specifically, refer to table 3.
TABLE 3 Table 3
Combining two adjacent channels into one Beam according to the channel number of the 64-channel AAU antenna, defining the Beam as SRS Beam, and numbering the SRS Beam, wherein the Beam 0 comprises a channel 0 and a channel 32; beam 1 includes channel 1 and channel 33; beam 19 includes channel 19 and channel 51; similarly, beam 30 includes channel 30 and channel 62; beam 31 includes channel 31 and channel 63.
Specifically, the horizontal distribution and the vertical distribution corresponding to the sounding reference signal are as shown in fig. 5:
the highest layer beams distributed vertically are respectively from left to right:
Beam23/Beam22/Beam21/Beam20/Beam19/Beam18/Beam17/Beam16
the bottom-most beams distributed vertically are respectively from left to right:
Beam31/Beam30/Beam29/Beam28/Beam27/Beam26/Beam25/Beam24
In a specific implementation, the beam statistics duty ratio of each sounding reference signal is calculated, and the number of access users and the average throughput duty ratio are sequentially calculated, as shown in table 4, so that the number of users and the traffic in the vertical direction can be further obtained on the basis of obtaining the number of users and the traffic in the horizontal direction.
TABLE 4 Table 4
According to the statistical result, the position distribution of the users in the vertical direction can be obtained, and the number of the broadcast beams in the vertical direction can be set for the cell according to the statistical result.
According to the embodiment, the user dense area in the horizontal direction of the target area is identified according to the number of users or the data throughput in the coverage area of the broadcast beam, so that the positioning of the first-order user is realized; and the beam data volume ratio of the home channel of the sounding reference signal is calculated, so that the identification of the user dense area in the vertical direction in the target area is realized, the ratio of the user position in the beam configuration is improved, and the coverage rate of the broadcast beam of the whole user in the target area is improved.
Referring to fig. 6, fig. 6 is a flow chart of a third embodiment of a beam configuration method according to the present invention.
Based on the above second embodiment, in this embodiment, the step S40 includes:
step S401: acquiring a detection period of each detection reference signal;
it should be noted that, the sounding period of the sounding reference signal refers to a sounding reference signal transmission period of a user, that is, if the user transmits the sounding reference signal once every X slots (or ms), X is the slot period of the sounding reference signal of the user.
Step S402: and carrying out beam parameter configuration on the broadcast beam according to the detection period, the first user intensive area and the second user intensive area.
When the parameter configuration of the broadcast beam is performed, the first user dense area mainly characterizes the user position distribution in the horizontal direction in the target area, and the second user dense area mainly characterizes the user position distribution in the vertical direction in the target area, so that the beam deployment mode and the deployment quantity in the horizontal direction of the broadcast beam can be configured according to the first user dense area, and the beam deployment mode and the deployment quantity in the vertical direction of the broadcast beam can be configured through the second user dense area.
Further, the configuring the beam parameters of the broadcast beam according to the detection period, the first user-dense area and the second user-dense area includes:
Determining that the horizontal deployment mode of the broadcast beam is a preset first deployment mode and the horizontal deployment quantity of the broadcast beam is a first preset threshold value in the first user dense region as a lateral wing region in the horizontal direction in the target region, wherein the sum of the first preset threshold value and the detection period is smaller than the quantity of activated antenna units;
And determining that the horizontal deployment mode of the broadcast beam is a preset first deployment mode or a preset second deployment mode in the middle area of the first user dense area in the horizontal direction, wherein the number of the horizontal deployments of the broadcast beam corresponding to the preset first deployment mode is a first preset threshold value, and the number of the horizontal deployments of the broadcast beam corresponding to the preset second deployment mode is 1.
