The technical solution provided by this application brings at least the following beneficial effects: Based on any of the above aspects, the present application provides an air interface performance evaluation method, including: an electronic device can obtain multiple first physical resource block PRB numbers of a target cell within a first preset period. Among them, the first PRB number is the number of PRBs in the target cell determined based on the MCS index in the RANK and MCS table. Afterwards, the electronic device can determine the target air interface efficiency of the target cell within the first preset period based on each first PRB number and the spectral efficiency corresponding to each first PRB number. The spectral efficiency corresponding to the first PRB number is determined based on the first MCS table and the first MCS index corresponding to the first PRB number. From the above, it can be seen that the electronic device can obtain the RANK within the first preset period and the number of PRBs corresponding to the MCS index in the MCS table.

Since the first PRB number is the PRB number in the MASSIVE MIMO scenario, the first PRB number includes the capacity of each RANK in the target cell. In this way, the electronic device can jointly determine the target air interface efficiency of the target cell within the first preset period through the first PRB number and the spectrum efficiency, and represent the air interface performance of the cell through the target air interface efficiency. In addition, since the first number of PRBs may be the number of PRBs in the MU-MIMO scenario in the entire target cell, the target air interface efficiency may be the air interface efficiency in the MU-MIMO scenario. Furthermore, since the first number of PRBs is the number of PRBs in the target cell within the first preset period, the air interface efficiency of the entire target cell may be represented by the target air interface efficiency.

As described in the background technology, the air interface efficiency of a cell is a very important indicator and plays a vital role in network optimization. In a 5G network, there are multiple ways to measure the air interface efficiency of a cell. At present, after the introduction of MASSIVE MIMO technology in 5G networks, the existing measurement methods are no longer applicable to MASSIVE MIMO scenarios. Therefore, there is an urgent need for a measurement method for air interface efficiency in MASSIVE MIMO scenarios. After the introduction of MASSIVE MIMO technology in 5G networks, the air interface capacity of the cell has been greatly improved. The air interface resources on the wireless side of the 5G network have expanded from the previous two-dimensional time domain and frequency domain to the three-dimensional time domain, frequency domain, and air domain. Therefore, when measuring the air interface efficiency of the cell, the impact of the air domain on the air interface efficiency also needs to be considered. In addition, MASSIVE MIMO technology includes single-user MIMO (SU-MIMO) and multi-user MIMO (MU-MIMO). When evaluating the air interface efficiency of a cell, it is also necessary to consider the air interface efficiency in both SU-MIMO and MU-MIMO scenarios. The following is a method for evaluating the air interface efficiency of a cell in the prior art: (1) The 28.552 protocol of the 3rd Generation Partnership Project (3GPP) defines the channel quality indication (CQI) related measurements reported by the user equipment (UE), which is the wideband CQI distribution measurement, CARR.WBCQIDist.BinX.BinY.BinZ. This method evaluates the downlink air interface performance through the CQI distribution reported by the UE. The specific method is: each time the UE reports a wideband CQI measurement result, the index value (BinX), the number of rank space division multiplexing streams (RANK) value (BinY), and the table (BinZ) corresponding to the CQI reported by the UE are accumulated. This method counts the number of CQIs reported by UEs by distinguishing tables, RANKs, and indexes. However, the statistical results of this method are relatively discrete, and the CQI of the entire cell cannot be normalized. It can only represent the air interface performance corresponding to each UE, but not the air interface performance of the entire cell. In addition, since different RANKs correspond to the same CQI index, the corresponding spectral efficiency is different. Therefore, this method is only applicable to SU-MIMO scenarios, and cannot evaluate the air interface performance of the entire cell in MU-MIMO scenarios. (2) The 3GPP 28.552 protocol defines the MCS-related measurements of uplink and downlink scheduled by the base station, which is called the PDSCH channel / PUSCH channel MCS distribution measurement, CARR.PDSCHMCSDist.BinX.BinY.BinZ / CARR.PUSCHMCSDist.BinX.BinY.BinZ. This method is to define the measurement through the MCS distribution of the actual uplink and downlink scheduling of the base station. The specific method is: each time the base station allocates the MCS level to the upper PRB for scheduling on the downlink PDSCH channel / uplink PUSCH channel, the number of PRBs is accumulated according to the allocated MCS index, that is, the index value (BinX), RANK (BinY), and table (BinZ) corresponding to the scheduling MCS on the downlink PDSCH channel / uplink PUSCH channel are accumulated. In addition, in the MU-MIMO scenario, a single PRB can be scheduled to UEs of multiple different RANKs and multiple different MCSs. In this case, the single PRB will be repeatedly calculated into the statistics of the number of PRBs corresponding to each scheduled RANK and each MCS. This method counts the number of MCS reports by distinguishing tables, RANKs, and indexes. However, the statistical results of this method are relatively discrete and cannot represent the air interface performance of the entire cell. In addition, when different RANKs correspond to the same MCS index, the corresponding spectrum The efficiency is different, so this method is only applicable to the SU-MIMO scenario, but cannot evaluate the air interface performance of the entire cell in the MU-MIMO scenario. (3) The 3GPP 28.552 protocol defines the indicator of "average air interface efficiency that can be achieved by a single UE in a cell". This indicator is calculated based on the CQI distribution. The spectrum efficiencies corresponding to the CQIs of different RANKs in different tables are aggregated and averaged to obtain the air interface efficiency indicator of a single user at the cell level. Since CQI is an indicator reported by UE, it can only be used for air interface performance evaluation in downlink scenarios, but not in uplink scenarios. In addition, this indicator can only be used for the calculation of single-user air interface efficiency in SU-MIMO scenarios, but not in MU-MIMO scenarios. To facilitate understanding, the following terms involved in this application are first explained. (1) MASSIVE MIMO MASSIVE MIMO, also known as massive multi-antenna technology, is a key technology for 5G networks. It increases network space resources by adding antennas, thereby improving the overall network capacity. MASSIVE MIMO is divided into SU-MIMO and MU-MIMO based on the number of users scheduled on a single frequency resource. SU-MIMO, also known as single-user multiple-input multiple-output, improves the network efficiency of UE and base station quality inspection by transmitting multiple links simultaneously. However, multiple parallel data streams occupying the same time-frequency resources can only be scheduled to one UE, thereby improving the data transmission rate of the single-user UE. MU-MIMO can also be called multi-user multiple-input multiple-output. On the basis of SU-MIMO, a multi-user communication mechanism is added. Multiple UEs share the same time-frequency resources through space division, so that additional multi-user diversity gain can be obtained through multi-user scheduling in the spatial dimension. At the same time and in the same frequency band, the base station can communicate with multiple UEs. Therefore, MU-MIMO can utilize all wireless bandwidth, and when multiple UEs are accessed, data can be transmitted with the network side at the same time, increasing space division capabilities and improving network resource utilization. (2)MCS and efficiency The network equipment can provide the number of PRBs scheduled by different MCSs reported by different RANKs in the uplink and downlink of the cell during the statistical time period. In the 3GPP 38.214 protocol, four MCS Tables are defined for downlink and two MCS Tables are defined for uplink. Different tables represent different modulation and coding strategies. The name and function of each table are as follows: Downlink PDSCH channel: PDSCH MCS table 1: The corresponding network turns on 64-phase quadrature amplitude modulation (QAM), PDSCH MCS table 2: The corresponding network enables 256QAM, PDSCH MCS table 3: the corresponding network enables Ultra-Reliable Low-Latency Communications (URLLC), PDSCH MCS table 4: the corresponding network enables 1024QAM. Uplink PUSCH channel: PUSCH MCS table 1: 64QAM is enabled in the corresponding network, PUSCH MCS table 2: URLLC is enabled in the corresponding network. Each MCS table includes the relationship between the MCS index and the efficiency. Table 1 shows the corresponding relationship of the downlink PDSCH MCS table 1. Table 1 Among them, MCS index I mcs Indicates MCS index, Modulation Order Q m Indicates the modulation order, Target code Rate R*

The spectral efficiency corresponding to the first PRB number is determined based on the first MCS table and the first MCS index corresponding to the first PRB number. From the above, it can be seen that the electronic device can obtain the RANK within the first preset period and the number of PRBs corresponding to the MCS index in the MCS table. Since each MCS table includes the relationship between the MCS index and the spectrum efficiency, the electronic device can determine the spectrum efficiency corresponding to each first PRB number through the first MCS table and the first MCS index corresponding to each PRB number, so that the electronic device can determine the target air interface efficiency through each first PRB number and the spectrum efficiency corresponding to each first PRB number. Since the first PRB number is the PRB number in the MASSIVE MIMO scenario, the first PRB number includes the capacity of each RANK in the target cell. In this way, the electronic device can jointly determine the target air interface efficiency of the target cell within the first preset period through the first PRB number and the spectrum efficiency, and represent the air interface performance of the cell through the target air interface efficiency. In addition, since the first number of PRBs may be the number of PRBs in the MU-MIMO scenario in the entire target cell, the target air interface efficiency may be the air interface efficiency in the MU-MIMO scenario. Furthermore, since the first number of PRBs is the number of PRBs in the target cell within the first preset period, the air interface efficiency of the entire target cell may be represented by the target air interface efficiency.

As shown in FIG3 , the air interface performance evaluation method provided in the embodiment of the present application includes: S301. An electronic device obtains a plurality of first PRB quantities of a target cell within a first preset period. The first PRB number is the PRB number determined in the target cell based on the RANK and the MCS index in the MCS table. Optionally, there can be multiple RANKs, the value of RANK can be 1-8, there can be multiple MCS tables, the MCS tables corresponding to the downlink channel can be 4, the MCS tables corresponding to the uplink channel can be 2, there can be multiple MCS indexes, and the value range can be 0-31. Specifically, the electronic device can obtain the target cell from the network management device within the first preset period. The performance management (PM) data of the O domain (operation support system) is obtained, and the first number of PRBs determined by RANK, MCS table, and MCS index are obtained therefrom. RANK represents the value of the space division multiplexing stream called by the PRB, the MCS table represents the MCS mode (such as 64QAM, 256QAM, etc.) determined by the base station for the PRB, and the MCS index is used to represent the modulation order and target code rate in the MCS mode determined by the base station for the PRB. Therefore, the first number of PRBs is the number of PRBs that meet the three dimensions of RANK, MCS table, and MCS index. It should be understood that the MCS table and the first MCS table in the embodiment of the present application are indexes of the MCS table. Optionally, the first preset period may be a preset time period, such as fifteen minutes. S302: The electronic device determines a target air interface efficiency of a target cell within a first preset period based on each first number of PRBs and a spectrum efficiency corresponding to each first number of PRBs. The spectrum efficiency corresponding to the first PRB number is determined based on the first MCS table and the first MCS index corresponding to the first PRB number. It should be understood that the first PRB number is the PRB number corresponding to the first RANK, the first MCS table, and the first MCS index. Specifically, since the first PRB number is determined based on RANK, MCS table, and MCS index, the electronic device can determine the first MCS table corresponding to the first PRB number, and the first MCS index corresponding to the first PRB number. Then, the electronic device can determine the spectral efficiency corresponding to the first PRB number based on the relationship between the MCS index and the spectral efficiency in the MCS table (i.e., the corresponding relationship in Tables 1 to 6 above), the first MCS table, and the first MCS index. Afterwards, the electronic device can determine the target air interface efficiency based on each first PRB number and the spectrum efficiency corresponding to each PRB number. Since the first PRB number is the PRB number in the MASSIVE MIMO scenario, the first PRB number includes the capacity of each RANK in the target cell. In this way, the electronic device can jointly determine the target air interface efficiency of the target cell within the first preset period through the first PRB number and the spectrum efficiency, and represent the air interface performance of the cell through the target air interface efficiency. In addition, since the first number of PRBs may be the number of PRBs in the MU-MIMO scenario in the entire target cell, the target air interface efficiency may be the air interface efficiency in the MU-MIMO scenario. Furthermore, since the first number of PRBs is the number of PRBs in the target cell within the first preset period, the air interface efficiency of the entire target cell may be represented by the target air interface efficiency. Optionally, the electronic device may determine the product of each first PRB number and the spectral efficiency of each first PRB number as the target air interface efficiency, which is not limited in the embodiment of the present application. In some embodiments, in combination with FIG. 3, as shown in FIG. 4, the target air interface efficiency includes a first type of air interface efficiency; in the above S302, the electronic device determines the target air interface efficiency of the target cell within the first preset period based on each first PRB number and the spectrum efficiency corresponding to each first PRB number, and specifically includes: S401. An electronic device obtains a second number of PRBs of a target cell within a first preset period. The second PRB number is the PRB number occupied by the channel in the target cell. Specifically, the electronic device can obtain the O domain PM data of the target cell within the first preset period from the network management device, and obtain the number of PRBs occupied by the channel of the target cell within the first preset period from the obtained O domain PM data, that is, the second PRB number. It should be noted that since the second number of PRBs is the actual number of PRBs occupied by the channel, and the first number of PRBs is the number of PRBs corresponding to the target RNAK, target MCS table, and target MCS index, in the MU-MIMO scenario, a PRB can be scheduled on different RANKs, so the same PRB can be repeatedly counted in different numbers of PRBs. In this way, in the MU-MIMO scenario, the first number of PRBs is greater than the second number of PRBs, and in the SU-MIMO scenario, the first number of PRBs is the same as the second number of PRBs. S402: The electronic device determines a spectrum efficiency corresponding to each first number of PRBs based on a first MCS index and a first MCS table. Specifically, the electronic device can determine the spectrum efficiency corresponding to the first PRB number based on the correspondence between the MCS index and the spectrum efficiency in the MCS table (ie, the correspondence in Tables 1 to 6 above), as well as the first MCS table and the first MCS index. S403: The electronic device determines a ratio of a sum of the plurality of first products to the second number of PRBs as a first type of air interface efficiency. Among them, any first product is the product of the first PRB number, the first RANK corresponding to the first PRB number, and the spectrum efficiency corresponding to the first PRB number. Specifically, the electronic device may also determine the RANK corresponding to the first PRB number. Afterwards, the electronic device may determine the product of the RANK corresponding to the first PRB number, the spectrum efficiency, and the first PRB number as the first product. Afterwards, since the first PRB number is any one of a plurality of first PRB numbers, the first product is multiple. Subsequently, the electronic device may determine the ratio of the sum of the plurality of first products to the second PRB number as the first type of air interface efficiency. Since the first PRB number is the number in the MU-MIMO scenario, RANK is the same as the first The product of the number of PRBs can be expressed as the air interface capability of the target cell, so that the electronic device can determine the first type of air interface efficiency of the target cell through RANK, the first number of PRBs, the spectrum efficiency, and the second number of PRBs. Therefore, the calculated first type of air interface efficiency includes the air interface capability of the target cell and can also represent the average air interface efficiency of the entire target cell in the MU-MIMO scenario. In a possible implementation manner, the channel of the target cell is a downlink PDSCH channel or an uplink PUSCH channel; when the channel of the target cell is a downlink PDSCH channel, the first type of air interface efficiency should satisfy the following formula: in, is the first type of air interface efficiency. X is the value of RANK corresponding to the first PRB number. Y is the value of the MCS table corresponding to the first PRB number; and Z is the value of the MCS index corresponding to the first PRB number. The first PRB number determined when RANK is X, MCS table is Y, and MCS index is Z. is the spectrum efficiency corresponding to the first number of PRBs when the first MCS table is Y and the first MCS index is Z.

AvgDLMcsEfficiency_Cell can represent the first type of air interface efficiency of the downlink PDSCH channel of the target cell within the first preset period. Through the above formula, the electronic device can normalize multiple MCS tables to calculate the first type of air interface efficiency representing the entire target cell. In addition, since the first PRB number is the data source of the single-terminal (or single-user) RANK, this solution can realize the calculation of the air interface efficiency of the MU-MIMO scenario by the data source of the single-terminal RANK. In a possible implementation, the channel of the target cell is a downlink PDSCH channel or an uplink PUSCH channel; when the channel of the target cell is an uplink PUSCH channel, the first type of air interface efficiency should satisfy the following formula: in, is the first type of air interface efficiency; X is the RANK value corresponding to the first PRB number; Y is the value of the MCS table corresponding to the first PRB number; Z is the first The value of the MCS index corresponding to the number of PRBs; CARR.PUSCHMCSDist.BinX.BinY.BinZ is the first number of PRBs determined when RANK is X, MCS table is Y, and MCS index is Z; is the spectrum efficiency corresponding to the first number of PRBs when the first MCS table is Y and the first MCS index is Z; M1(T) is the second number of PRBs.

AvgDLMcsEfficiency_Cell can represent the first type of air interface efficiency of the uplink PUSCH channel of the target cell within the first preset period. Through the above formula, the electronic device can normalize multiple MCS tables to calculate the first type of air interface efficiency representing the entire target cell. In addition, since the first PRB number is the data source of the single-terminal (or single-user) RANK, this solution can realize the calculation of the air interface efficiency of the MU-MIMO scenario by the data source of the single-terminal RANK. In some embodiments, in combination with FIG. 4, as shown in FIG. 5, the target air interface efficiency includes a second type of air interface efficiency; in the above S302, the electronic device determines the target air interface efficiency of the target cell within the first preset period based on each first PRB number and the spectrum efficiency corresponding to each first PRB number, and specifically includes: S501. The electronic device determines a spectrum efficiency corresponding to each first number of PRBs based on a first MCS index and a first MCS table. Specifically, the electronic device can determine the spectrum efficiency corresponding to the first PRB number based on the correspondence between the MCS index and the spectrum efficiency in the MCS table (ie, the correspondence in Tables 1 to 6 above), as well as the first MCS table and the first MCS index. S502: The electronic device determines a ratio of a sum of a plurality of second products to a sum of a plurality of first PRB quantities as a second type of air interface efficiency. Among them, any first product is the product of the second PRB number, the RANK corresponding to the first PRB number, and the spectrum efficiency corresponding to the first PRB number. Specifically, the electronic device may determine the product of the RANK corresponding to the first PRB number, the spectrum efficiency, and the first PRB number as the second product. Afterwards, since the first PRB number is multiple, the second product is multiple. Subsequently, the electronic device may determine the ratio of the sum of the multiple second products to the sum of the multiple first PRB numbers as the second type of air interface efficiency. Since the first PRB number is the number in the MASSIVE MIMO scenario, and RANK is The product of the first number of PRBs can be expressed as the air division capability of the target cell, so that the electronic device can determine the second type of air interface efficiency of the target cell through RANK, the first number of PRBs, and the spectrum efficiency. Therefore, the calculated second type of air interface efficiency includes the air division capability of the target cell. In addition, whether in the SU-MIMO scenario or the MU-MIMO scenario, the number of PRBs in the numerator and denominator in the formula is the same, so the second type of air interface efficiency can be used to represent the air interface efficiency of a single terminal in the MASSIVE MIMO scenario. In a possible implementation, the channel of the target cell is a downlink PDSCH channel or an uplink PUSCH channel; when the channel of the target cell is a downlink PDSCH channel, the second type of air interface efficiency should satisfy the following formula: in, Second type of air interface efficiency. X is the value of RANK corresponding to the first number of PRBs. Y is the value of the MCS table corresponding to the first number of PRBs. Z is the value of the MCS index corresponding to the first number of PRBs. CARR.PDSCHMCSDist.BinX.BinY.BinZ is the first number of PRBs determined when RANK is X, MCS table is Y, and MCS index is Z. It is the spectrum efficiency corresponding to the first PRB number when the first MCS table is Y and the first MCS index is Z. It should be understood that in CARR.PDSCHMCSDist.BinX.BinY.BinZ, X represents the first RANK corresponding to the first PRB number, and the value range is 1-8, Y represents the first MCS table (or table index, i.e., Table 1-Table 4) corresponding to the first PRB number, and the value range is 1-4, and Z represents the first MCS index (index) corresponding to the first PRB number, and the value range is 0-31. AvgDLMcsEfficiency_UE can represent the second type of air interface efficiency of the downlink PDSCH channel of the target cell within the first preset period. Through the above formula, the electronic device can normalize multiple MCS tables to calculate the second type of air interface efficiency representing the entire target cell. In addition, whether in the SU-MIMO scenario or the MU-MIMO scenario, the number of PRBs in the numerator and denominator in the formula is the same, so the second type of air interface efficiency can be used to represent the air interface efficiency of a single terminal in the MASSIVE MIMO scenario. In a possible implementation, the channel of the target cell is a downlink PDSCH channel or an uplink PUSCH channel; when the channel of the target cell is an uplink PUSCH channel, the second type of air interface efficiency should satisfy the following formula: in, Second type air interface efficiency.

Z is the value of the MCS index corresponding to the first PRB number. The first PRB number determined when RANK is X, MCS table is Y, and MCS index is Z. It is the spectrum efficiency corresponding to the first PRB number when the first MCS table is Y and the first MCS index is Z. It should be understood that in CARR.PUSCHMCSDist.BinX.BinY.BinZ, X represents the RANK corresponding to the first PRB number, and the value range is 1-8, Y represents the MCS table (or table index, i.e., Table 1-Table 2) corresponding to the first PRB number, and the value range is 1-2, and Z represents the MCS index (index) corresponding to the first PRB number, and the value range is 0-31. AvgDLMcsEfficiency_Cell can represent the second type of air interface efficiency of the uplink PUSCH channel of the target cell within the first preset period.

The electronic device determines a spectrum efficiency corresponding to each first number of PRBs based on a first MCS index and a first MCS table. Specifically, the electronic device can determine the spectrum efficiency corresponding to the first PRB number based on the correspondence between the MCS index and the spectrum efficiency in the MCS table (ie, the correspondence in Tables 1 to 6 above), as well as the first MCS table and the first MCS index. S602: The electronic device determines a ratio of a sum of multiple third products to a sum of multiple first PRB numbers as a third type of air interface efficiency. Wherein, any third product is a product of the first PRB quantity and the RANK corresponding to the first PRB quantity. The first PRB quantity is any one of a plurality of first PRB quantities. Specifically, the electronic device may determine the product of the spectrum efficiency corresponding to the first PRB number and the first PRB number as the third product. Afterwards, since the first PRB number is multiple, the third product is multiple. Subsequently, the electronic device may sum the multiple third products with the multiple first PRBs. The ratio of the sum of the number of PRBs is determined as the third type of air interface efficiency. Since the first PRB number is the number in the MASSIVE MIMO scenario, the electronic device can determine the third type of air interface efficiency of the target cell by the first PRB number and the spectrum efficiency. Since the influence of RANK is not considered in the third type of air interface efficiency, the third type of air interface efficiency can represent the air interface efficiency of the time-frequency two-dimensional. In this way, the electronic device can determine the air interface efficiency of the time-frequency two-dimensional by the first PRB number and the spectrum efficiency in the MASSIVE MIMO scenario. In a possible implementation, the channel of the target cell is a downlink PDSCH channel or an uplink PUSCH channel; when the channel of the target cell is a downlink PDSCH channel, the third type of air interface efficiency should satisfy the following formula: Wherein, AvgDLMcsEfficienc is the third type of air interface efficiency; X is the value of RANK corresponding to the first PRB number; Y is the value of the MCS table corresponding to the first PRB number; Z is the value of the MCS index corresponding to the first PRB number; The first PRB number determined when RANK is X, MCS table is Y, and MCS index is Z; It is the spectrum efficiency corresponding to the first PRB number when the first MCS table is Y and the first MCS index is Z.

Through the above formula, the electronic device can normalize multiple MCS tables to calculate the third type of air interface efficiency representing the entire target cell. In addition, since the influence of RANK is not considered in the third type of air interface efficiency, the third type of air interface efficiency can represent the air interface efficiency of the time-frequency two-dimensional. In this way, the electronic device can determine the air interface efficiency of the time-frequency two-dimensional by the first PRB number and spectrum efficiency in the MASSIVE MIMO scenario. In a possible implementation, the channel of the target cell is a downlink PDSCH channel or an uplink PUSCH channel; when the channel of the target cell is an uplink PUSCH channel, the third type of air interface efficiency should satisfy the following formula: Among them, AvgULMcsEfficienc is the third type of air interface efficiency; X is the number of first PRBs corresponding to Y is the value of the MCS table corresponding to the first PRB number; Z is the value of the MCS index corresponding to the first PRB number; CARR.PUSCHMCSDist.BinX.BinY.BinZ is the first PRB number determined when RANK is X, MCS table is Y, and MCS index is Z; It is the spectrum efficiency corresponding to the first PRB number when the first MCS table is Y and the first MCS index is Z. It should be understood that in CARR.PUSCHMCSDist.BinX.BinY.BinZ, X represents the RANK corresponding to the first PRB number, and the value range is 1-8, Y represents the MCS table (or table index, i.e., Table 1-Table 2) corresponding to the first PRB number, and the value range is 1-2, and Z represents the MCS index (index) corresponding to the first PRB number, and the value range is 0-31. AvgULMcsEfficiency can represent the third type of air interface efficiency of the uplink PUSCH channel of the target cell within the first preset period. Through the above formula, the electronic device can normalize multiple MCS tables to calculate the third type of air interface efficiency representing the entire target cell. In addition, since the influence of RANK is not considered in the third type of air interface efficiency, the third type of air interface efficiency can represent the air interface efficiency of the time-frequency two-dimensional. In this way, the electronic device can determine the air interface efficiency of the time-frequency two-dimensional by the first PRB number and spectrum efficiency in the MASSIVE MIMO scenario. In some embodiments, in combination with FIG. 6 , as shown in FIG. 7 , in the above S401, the electronic device obtains the second PRB number of the target cell within the first preset period specifically includes: S701. The electronic device determines a sum of multiple third PRB quantities as a second PRB quantity. Among them, any third PRB number is the number of PRBs occupied by each scheduling of the channel of the target cell within the first preset period. Specifically, within the first preset period, the channel of the target cell will be scheduled multiple times, and the number of PRBs occupied by the channel each time is different, so the electronic device can obtain the number of PRBs occupied by the channel each time it is scheduled and determine it as the third number of PRBs. Then, the electronic device can accumulate the number of PRBs occupied by the channel during multiple scheduling to obtain the second number of PRBs, that is, the electronic device determines the sum of the third number of PRBs as the second number of PRBs. It should be understood that the electronic device can obtain the number of PRBs occupied in each scheduling from the O-domain PM data. The channel of the target cell is an uplink channel or a downlink channel. In some embodiments, in combination with FIG. 7 , as shown in FIG. 8 , in the above S401, the electronic device obtains the second PRB number of the target cell within the first preset period specifically includes: S801. The electronic device determines the product of a target PRB utilization rate and a target number of available PRBs as a second number of PRBs. The target PRB utilization rate is the channel utilization rate of the target cell within the first preset period. PRB utilization rate: The target available PRB number is the cumulative value of the number of PRBs available for the channel of the target cell during multiple scheduling within the first preset period. Specifically, each time the channel is scheduled, there will be multiple available PRBs for the channel to be scheduled. However, at each scheduling, the channel usually does not occupy all available PRBs. Therefore, the electronic device can obtain the PRB utilization of the number of PRBs occupied by the channel of the target cell within the first preset period as the target PRB utilization. Then, the electronic device can obtain the number of PRBs available for each scheduling of the channel within the first preset period, and determine the cumulative value of the number of available PRBs when the channel of the target cell is scheduled multiple times as the target number of available PRBs. Subsequently, the electronic device can determine the product of the target PRB utilization and the target number of available PRBs as the second number of PRBs. In some embodiments, in combination with FIG. 8 , as shown in FIG. 9 , in the above S401, the electronic device obtains the second PRB number of the target cell within the first preset period specifically includes: S901. The electronic device determines the product of a fourth PRB number and the number of scheduling times of a channel of a target cell within a first preset period as a second PRB number. The fourth PRB number is the average number of PRBs occupied by the channel of the target cell during multiple schedulings within the first preset period. Specifically, the electronic device may obtain the average number of PRBs occupied by each scheduling when the channel of the target cell is scheduled multiple times within the first preset period, and determine it as the fourth PRB number. Then, the electronic device may obtain the number of scheduling times of the channel of the target cell within the first preset period, and determine the product of the fourth PRB number and the scheduling number as the second PRB number. In some embodiments, in combination with FIG. 9 , as shown in FIG. 10 , in the above S401, the electronic device obtains the second PRB number of the target cell within the first preset period specifically includes: S1001. The electronic device determines a sum of a plurality of fifth PRB quantities as a second PRB quantity. Among them, any fifth PRB quantity is the cumulative value of the PRB quantity of multiple empty layers when the channel of the target cell is scheduled at each preset time within the first preset period. Specifically, when the channel of the target cell is scheduled, since the PRB is divided into multiple empty layers for scheduling, at each moment, each empty layer includes multiple corresponding PRBs. In this case, the electronic device can divide the first preset period into multiple preset moments, and obtain the cumulative value of the number of PRBs of multiple empty layers when the channel of the target cell is scheduled at each preset moment, and determine it as the fifth PRB number. Since there are multiple preset moments, the fifth PRB number is also multiple. Afterwards, the electronic device can determine the sum of multiple fifth PRB numbers as the second PRB number. The above mainly introduces the solution provided by the embodiment of the present application from the perspective of the method.
