Embodiment one

The embodiment of the present invention provides a kind of calculation method of uplink throughput, includes: as shown in Figure 4

The first uplink of at least one measurement point gulps down in the coverage area of S101, the scene map for obtaining cell and cell The amount of spitting and CSI-RSRP value.

It should be noted that obtaining the first uplink throughput and CSI- of at least one measurement point in the coverage area of cell RSRP value, comprising: at least one measurement point is chosen to the quasi- cell for calculating downlink throughput capacity, it is more by being placed in each test point The UE of group quantity, and periodically collect corresponding CSI-RSRP value and uplink throughput number when the UE for placing different groups of quantity According to.

Illustratively, the CSI-RSRP value and downlink throughput capacity data of a UE can be collected with each second.

Specifically, in actual application, it is corresponding since single measurement point is when placing single UE and multiple UE CSI-RSRP value and downlink throughput capacity data can change；Therefore, exist to more accurately calculate single measurement point The difference of its CSI-RSRP value when placing single UE and multiple UE, needs to determine in the following manner, concrete implementation process It is as follows:

(quantity of measurement point is more, its CSI- when obtained single UE and multiple UE firstly, the different measurement point of selection The difference of RSRP value is more accurate)；Then, the UE of different number is placed respectively in each measurement point, and collect and place every kind of number Corresponding average CSI-RSRP value and average uplink throughput data when the UE of amount；Illustratively, it is first placed in each measurement point One UE carries out UDP or ftp business, and records its CSI-RSRP value and uplink throughput data；Then it is put in the measurement point It sets 4 UE and carries out UDP or ftp business, and record its average CSI-RSRP value and average uplink throughput data；Then at this Measurement point places 10 UE and carries out UDP or ftp business, and records its average CSI-RSRP value and average uplink throughput number According to.Illustratively, it is assumed that the measurement point selected for CSI-RSRP value is -80, CSI-RSRP value is -90, CSI-RSRP value be - 95, CSI-RSRP value is -100, CSI-RSRP value is -105, CSI-RSRP value is -110, CSI-RSRP value is -115, CSI- RSRP value is -120, CSI-RSRP value be -125 and CSI-RSRP value be -130 this 10 points is measurement point, the data of record It is as shown in table 1:

Table 1

Obtain the difference between unit/terminal and multiple terminals CSI-RSRP:

Wherein, CSI-RSRP_MUIndicate the difference between unit/terminal and multiple terminals CSI-RSRP, CSI-RSRP_i-1UEIndicate measurement N is placed at point i₁Practical CSI-RSRP value when a UE, CSI-RSRP_i-4UEIt indicates to place N at measurement point i₂Reality when a UE CSI-RSRP value, CSI-RSRP_i-10UEIt indicates to place N at measurement point i₃Practical CSI-RSRP value when a UE, n indicate selection The total number of measurement point i, n are the integer more than or equal to 1.

Illustratively, it is assumed that the measurement point selected for CSI-RSRP value is -80, CSI-RSRP value is -90, CSI-RSRP value For -95, CSI-RSRP value be -100, CSI-RSRP value is -105, CSI-RSRP value is -110, CSI-RSRP value is -115, CSI-RSRP value is -120, CSI-RSRP value be -125 and CSI-RSRP value be -130 this 10 points is measurement point, then measures Point i can be CSI-RSRP value be -80, CSI-RSRP value is -90, CSI-RSRP value is -95, CSI-RSRP value is -100, CSI-RSRP value is -105, CSI-RSRP value is -110, CSI-RSRP value is -115, CSI-RSRP value is -120, CSI-RSRP Value is that -125 and CSI-RSRP value is any one measurement point in -130.

Illustratively, a UE is first placed in each measurement point and carry out UDP or ftp business, and record its CSI-RSRP Value and uplink throughput data；Then 4 UE are placed in the measurement point and carries out UDP or ftp business, and record its average CSI- RSRP value and average uplink throughput data；Then 10 UE are placed in the measurement point and carries out UDP or ftp business, and recorded When its average CSI-RSRP value and average uplink throughput data, the difference between unit/terminal and multiple terminals CSI-RSRP are as follows:

S102, according to CSI-RSRP value, determine the probability that CSI-RSRP value occurs in the section CSI-RSRP.

Optionally, according to CSI-RSRP value, the probability that CSI-RSRP value occurs in the section CSI-RSRP is determined, such as Fig. 5 institute Show and includes:

The circulation way of S1020, the antenna for obtaining cell and measurement point；Wherein, circulation way includes NLOS and LOS.

S1021, according to CSI-RSRP value, determine the cumulative distribution function (full name in English: Cumulative of CSI-RSRP value Distribution Function, referred to as: CDF).

It should be noted that determining the cumulative distribution function of CSI-RSRP value according to CSI-RSRP value, comprising:

The CSI-RSRP value obtained by step S101 determines the difference CSI- between unit/terminal and multiple terminals CSI-RSRP RSRP_MU, then according to CSI-RSRP_MUDetermine corresponding practical CSI-RSRP value and CSI- when each measurement point places single UE RSRP_MUDifference △ CSI-RSRP:

△ CSI-RSRP=CSI-RSRP_i-1UE-CSI-RSRP_MU。

Then, according to △ CSI-RSRP, the cumulative distribution function of the CSI-RSRP value under multi-user's distribution is fitted, is such as schemed Shown in 6；Wherein, the cumulative distribution function of CSI-RSRP value includes:

F (CSI-RSRP)=a × (CSI-RSRP)³+b×(CSI-RSRP)²+c×(CSI-RSRP)+d。

Wherein, a, b, c, d are respectively constant, and F (CSI-RSRP) is the probability that user occurs in the CSI-RSRP value.

It should be noted that obtained △ CSI-RSRP is more when the quantity of the measurement point of selection, fit The lower CSI-RSRP value of multi-user's distribution cumulative distribution function just more accurately；It therefore, here can be to cell progress time It goes through and (selects walking or speed to be less than the vehicles of 20km/h, by the CSI- of a drive test software single terminal of every t seconds record RSRP value), i.e., the point that can each pass through in each cell is measurement point, so that the accumulation of obtained CSI-RSRP value Distribution function is just more accurate.

S1022, according to cumulative distribution function and circulation way, determine that CSI-RSRP value is in CSI- under different circulation ways The probability that the section RSRP occurs.

It should be noted that in actual application, channel is particularly important to the influence of 5G MU-MIMO scene；Without Same circulation way, will affect channel to the influence of 5G MU-MIMO scene；And corresponding propagation when channel is established in UE and base station Mode is divided into NLOS and LOS, it is therefore desirable to which calculating circulation way is that NLOS (abbreviation NLOS diameter) corresponding CSI-RSRP value exists The probability and circulation way that the section CSI-RSRP occurs are LOS (abbreviation LOS diameter) corresponding CSI-RSRP value in CSI-RSRP The probability that section occurs, specific calculation are as follows:

For the actual distribution of better analog subscriber, so that total uplink throughput T under obtained NLOS diameter_NLOSAnd Total uplink throughput T under LOS diameter_LOSIt is more accurate；Therefore, it is necessary to collect the throughput data at the same position CSI-RSRP And the throughput data at the difference position CSI-RSRP.

Wherein, as follows with the collection process of the throughput data at the position CSI-RSRP:
