It should be noted that obtaining the first uplink throughput and SINR of at least one measurement point in the coverage area of cell Value, comprising: at least one measurement point is chosen to the quasi- cell for calculating downlink throughput capacity, by placing multiple groups number in each test point The UE of amount, and periodically collect corresponding SINR value and uplink throughput data when the UE for placing different groups of quantity.

Illustratively, the SINR 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 SINR value and downlink throughput capacity data can change；Therefore, it is being placed to more accurately calculate single measurement point The difference of its SINR value when single UE and multiple UE, needs to determine in the following manner, concrete implementation process is as follows:

(quantity of measurement point is more, its SINR value when obtained single UE and multiple UE firstly, the different measurement point of selection Difference it is more accurate)；Then, the UE of different number is placed respectively in each measurement point, and collect the UE for placing every kind of quantity When corresponding average sinr value and average uplink throughput data；Illustratively, a UE is first placed in each measurement point to carry out UDP business, and record its SINR value and uplink throughput data；Then 4 UE are placed in the measurement point and carries out UDP business, and Record its average sinr value and average uplink throughput data；Then 10 UE are placed in the measurement point and carries out UDP business, and remembered Record its average sinr value and average uplink throughput data.Illustratively, it is assumed that the measurement point selected for SINR value is 22, SINR Value is 20, SINR value 18, SINR value 15, SINR value 10, SINR value 8, SINR value 5, SINR value 3, SINR value It is 1 and SINR value be -1 this 10 points is measurement point, the data of record are as shown in table 1:

Table 1

Obtain the difference between unit/terminal and multiple terminals SINR:

Wherein, SINR_MUIndicate the difference between unit/terminal and multiple terminals SINR, SINR_i-1UEIt indicates to place N at measurement point i₁It is a Practical SINR value when UE, SINR_i-4UEIt indicates to place N at measurement point i₂Practical SINR value when a UE, SINR_i-10UEIt indicates to survey It measures and places N at point i₃Practical SINR value when a UE, n indicate the total number of the measurement point i of selection, and n is whole more than or equal to 1 Number.

Illustratively, it is assumed that the measurement point selected for SINR value is 22, SINR value 20, SINR value 18, SINR value are 15, SINR value 10, SINR value 8, SINR value 5, SINR value 3, SINR value are 1 and SINR value is that -1 this 10 points are Measurement point, then measurement point i can be SINR value be 22, SINR value 20, SINR value 18, SINR value 15, SINR value 10, SINR value is 8, SINR value 5, SINR value 3, SINR value are 1 and SINR value is any one measurement point in -1.

Illustratively, UE is first placed in each measurement point and carry out UDP business, and record its SINR value and uplink is handled up Measure data；Then 4 UE are placed in the measurement point and carries out UDP business, and record its average sinr value and average uplink throughput Data；Then 10 UE are placed in the measurement point and carries out UDP business, and record its average sinr value and average uplink throughput number According to when, difference between unit/terminal and multiple terminals SINR are as follows:

S102, according to SINR value, determine the probability that SINR value occurs in the section SINR.

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

The SINR value obtained by step S101 determines the difference SINR between unit/terminal and multiple terminals SINR_MU, then basis SINR_MUDetermine corresponding practical SINR value and SINR when each measurement point places single UE_MUDifference △ SINR:

△ SINR=SINR_i-1UE-SINR_MU。

Then, according to △ SINR, the cumulative distribution function of the SINR value under multi-user's distribution is fitted, as shown in Figure 6；Its In, the cumulative distribution function of SINR value includes:

F (SINR)=a × SINR³+b×SINR²+c×SINR+d。

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

It should be noted that obtained △ SINR is more, and what is fitted is more when the quantity of the measurement point of selection The cumulative distribution function of SINR value under user distribution is just more accurate；Therefore, cell can be traversed here and (selects step Capable or speed is less than the vehicles of 20km/h, by the SINR value of a drive test software single terminal of every t seconds record), i.e., each The point that can each pass through in cell is measurement point, so that the cumulative distribution function of obtained SINR value is just more quasi- Really.

S1022, according to cumulative distribution function and circulation way, determine that SINR value goes out in the section SINR under different circulation ways Existing probability.

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, needs to calculate what SINR value when circulation way is NLOS (abbreviation NLOS diameter) occurred in the section SINR The probability that SINR value occurs in the section SINR when probability and circulation way are LOS (abbreviation LOS diameter), specific calculation It is as follows:

For the actual distribution of better analog subscriber, so that total downlink throughput capacity T under obtained NLOS diameter_NLOSAnd Total downlink throughput capacity T under LOS diameter_LOSIt is more accurate；Therefore, it is necessary to collect throughput data at the same position SINR and Throughput data at the different positions SINR.
