Journey schematic diagram.
A kind of Massive mimo antenna azimuth, angle of declination and weight setting method are described in detail below.Such as
Shown in Fig. 2, this method may include this 3 big step of S110 to S130.
S110 acquires engineering parameter, measurement report, the cell parameter of current all cells of TD-LTE network.
In S110, engineering parameter may include: latitude and longitude of base station, antenna extension height, antenna model, antenna azimuth letter
Breath.Measurement report may include: MR.LteScRSRP, MR.LteNcRSRP, MR.LteScEarfcnMR.LteScPci,

Cell parameter may include: TD-LTE cell and its neighboring BS information.TDD frequency spectrum workable for TD-LTE system at present
It is as shown in Table 1 below:
TDD frequency spectrum workable for 1 TD-LTE system of table
Uplink and downlink carrier frequency indicates that EARFCN, that is, E-UTRA Absolute Radio Frequency Channel numbers (E-UTRA with EARFCN
Absolute Radio Frequency Channel Number, EARFCN), value range: 0-65535.
Now BAND 38 is known as D frequency range by net, and BAND 39 is known as F-band, and BAND 40 is known as E frequency range, makes in the network planning
It uses D frequency range and F-band to cover as outdoor wireless signal, uses E frequency range to cover as indoor radio signal, as a result, according to LTE
Frequency point setting, then in existing TD-LTE network, the frequency point number that respective frequency range uses is as shown in Table 2 below.Table 2 is TD-LTE
The corresponding frequency point number of system different frequency range.
2 TD-LTE system different frequency range of table corresponds to frequency point number
S120, the adjacent area sampled point for calculating main serving cell MR sampled point is the sampled point of room subsystem, calculates its accounting, such as super
A threshold value is crossed, then shows that main serving cell and neighbouring room subsystem cell have superimposed coverage area, then the main serving cell
It is suitble to use Massive mimo antenna.

Reference table 2, filter out room subsystem ownership the corresponding frequency point of E frequency range, as adjacent cell frequency point number be 38950 MR
Sampled point.
The adjacent area sampled point for calculating main serving cell MR sampled point is the sampled point Na of room subsystem, calculates its accounting, such as
Shown in table 3.
The adjacent area sampled point of 3 main serving cell MR sampled point of table is the sampled point accounting of room subsystem
Na=(∑ (Count (the MR sampled point that adjacent cell frequency point number is 38950)))/(∑ (Count (source cell MR sampled point)))
If Na is more than that a threshold value is usually arranged as 20% in existing TD-LTE network, in table 3, adjacent cell frequency point number is
38950 MR sampled point is 58675, and the accounting for accounting for all MR sampled points of main plot is 22.05%, then shows that main service is small
Area and neighbouring room subsystem cell have obvious overlapping coverage area, then the main serving cell is suitble to using Massive MIMO days
Line；
If Na is no more than different a threshold value, then S103 is executed.
S103 is then needed if the room of main serving cell MR sampled point divides the accounting of adjacent area sampled point to be no more than a threshold value
Determine whether the main serving cell covers building and whether user concentrates on building jointly by tri- parameters of TA, AOA, RSRP
It builds in object, thus adjudicates whether scene where the cell is the scene being suitble to using Massive mimo antenna.
If the room of main serving cell MR sampled point divides the accounting of adjacent area sampled point to be no more than a threshold value, show that source cell is covered
Do not include the building for building room subsystem within the scope of lid, need to judge whether wrap in the source cell coverage area in next step
Include whether the user being resident under building and source cell concentrates in some building.
S103-1 screens the Timing Advance (Timing Advance, TA) in MR measurement report, Timing Advance TA table
Levy the coverage distance of source cell.
Timing Advance Index title: MR.Tadv is defined as UE for adjusting its main plot PUCCH/PUSCH/SRS
The time that row is sent.Circular are as follows: in random access procedure, eNodeB receives pilot signal by measurement to determine
Time advance value, Timing Advance value range are (0,1,2 ..., 1282) × 16Ts；Under RRC connection status,
ENodeB determines the TA adjusted value of each UE based on the uplink of measurement corresponding UE, the range of this adjusted value be (0,1,
2 ..., 63) × 16Ts.
3GPP defines the calculation formula of Ts, and it is 2048 that OFDM symbol, which generates FFT Size, in LTE system, and LTE frequency point is pressed
20MHz is calculated, thus the non-15kHz of sample frequency, i.e. sample rate=15kHz*2048 of 20MHz bandwidth can be calculated: OFDM symbol
Sampling period Ts, i.e., period of one OFDM symbol is Ts=1/ (15000*2048).
Can calculate 1Ts corresponding Timing Advance distance be S=VT/2=(300000000)/(2*15000*2048)=
4.89m。
The corresponding coverage area in TA=0 be 16Ts, i.e., 78 meters, the corresponding coverage area in TA=1 be 32Ts, i.e., 156 meters.
From 0 to 192Ts, every 16Ts is a section to value range, corresponding MR.Tadv.00 to MR.Tadv.11；From 192Ts
It is a section to the every 32Ts of 1024Ts, corresponding MR.Tadv.12 to MR.Tadv.37；Every 256Ts is from 1024Ts to 2048Ts
One section, corresponding MR.Tadv.38 to MR.Tadv.41；Every 1048Ts is a section from 2048Ts to 4096Ts, corresponding
MR. Tadv.42 and MR.Tadv.43；It is a section greater than 4096Ts, corresponding MR.Tadv.44.
The MR measurement report for acquiring source cell, calculates the MR sampling number and its accounting in each Timing Advance section, such as
Shown in table 4.
The MR sampling number and its accounting in the section TA of 4 source cell of table

The sampled point accounting for calculating TA=0 and TA=1 (is suitable for dense city scene, can select according to the actual situation, such as calculate
∑ (Count (TA=0)+Count (TA=1) ...+Count (TA=n)):
Nb=(∑ (Count (TA=0)+Count (TA=1)))/(∑ (Count (source cell MR sampled point)))
If Nb is more than a threshold value, then show that the user of cell concentrates in the coverage area of TA=0 and TA=1, thus directed towards TA=
0 and TA=1 calculated.
S103-2, the AOA value and its corresponding RSRP value, AOA measurement data screened in MR measurement report can be used for really
Determine orientation locating for user.
AOA defines a user with respect to the anticlockwise estimation angle of reference direction.In this standard, it is specified that with reference to
Direction should be direct north.Meet value range condition in this measurement data expression measurement period counts antenna according to by stages
The number of samples of angle of arrival.There is the case where multiple antennas suitable for eNodeB.
RSRP is defined as on the frequency band for considering measurement, carries the power of the resource unit (RE) of cell own reference signal
