In order to better understand and explain the solutions of the embodiments of the present disclosure, some technologies involved in the embodiments of the present disclosure are briefly described below.
Coverage classification may include or be referred to as coverage level, coverage class, and so on.
The coverage characteristics may include RSRP, signal to interference plus noise ratio (SINR), reference signal receiving quality (RSRQ), or other indicators that indicate the coverage classification. According to the current 3GPP protocol, based on the division of coverage levels, NB-IoT supports up to 3 coverage levels and eMTC supports up to 4 coverage levels. The maximum number of coverage levels may change in other wireless communication systems or future 3GPP protocol.
According to the current 3GPP protocol, different coverage levels are determined by defining reference signal receiving power (RSRP) thresholds. In the future 3GPP protocol or in other wireless communication systems, the division of coverage classifications may be determined by defining other threshold indicators, including SINR, RSRQ or other indicators that identify coverage differences. In this case, RSRP is taken as an example.
The resource configuration (a set of parameters affected by RSRP threshold) for each coverage level may include random access resource configuration, which includes time domain/frequency domain resources for transmitting the preamble (msg1) and the number of repetitions of the preamble.
Where, time domain resources include time domain periods; frequency domain resources include the number of subcarriers; the number of repetitions of preamble represents the number of repetitions for transmission required for transmitting a preamble; scheduling resource configuration includes the number of repetitions for transmission and/or modulation and coding scheme (MCS) configuration for physical downlink control channel (PDCCH), physical downlink shared channel (PDSCH), physical uplink shared channel (PUSCH), physical uplink control channel (PUCCH).
Specifically, the IoT terminal may compare the measured signal strength (RSRP) with the RSRP threshold to determine the coverage level (CL) where it is located, and then use the corresponding (random access channel (RACH) resource to initiate random access, a base station selects the corresponding resource configuration based on the CL that the UE accesses. For example, for a CL with a good signal strength, the transmission requirement can be met without setting the number of repetitions or with a small amount of repetitions while ensuring a higher data transmission rate; for a CL with a poor signal strength, the coverage characteristics can be met by setting a larger number of repetitions.
The open radio access network (O-RAN) focuses on the needs of network intelligence, interface openness, open source software and hardware white box, which is intended to promote the openness of wireless device interfaces, and realize intelligent wireless networks by introducing new technologies such as artificial intelligence, thereby to raise the openness of the next generation wireless communication network to a new level.
According to the open radio access network (O-RAN) specification, the logical architecture of the open radio access network (O-RAN) is shown in FIG. 5. The entities of wireless side may include Near-RT RIC, O-CU-CP, O-CU-UP, O-DU, and O-eNB.
Service management and orchestration (SMO) entities may provide a variety of management services and network management functions, such as RAN management, core network management, transmission management, and end-to-end slice management.
Non-real time RAN intelligent controller (Non-RT RIC) is a logical entity built into SMO, which supports non-real-time control and optimization of RAN network elements and resources, AI/ML model establishing, reasoning and updating; RAN is optimized through data analysis and AI/ML training/reasoning, and it provides strategic guidance and ML model management to the near-real Time RAN intelligent controller (Near-RT RIC) through the A1 interface.
The Near-RT RIC logical entity may support near-real-time control and optimization of RAN network elements and resources, and may include artificial intelligence (AI)/ machine learning (ML) model training, reasoning and updating, and strategy guidance. The Near-RT RIC provides network optimization instructions to the E2 node through the E2 interface.
E2 node: which may include O-RAN control unit control plane (O-CU-CP), O-RAN control unit user plane (O-CU-UP), O-RAN data unit (O-DU), O-eNB and other entities, where O-CU-CP, O-CU-UP, and O-DU are used for 5G NR access, O-eNB is used for E-UTRA access. Compared with the CU-CP, CU-UP and DU of the non-O-RAN system, the E2 node adds support for the E2 interface.
O-eNB: which is eNB or ng-eNB supporting O-RAN architecture.
O-Cloud: which is O-RAN cloud computing platform.
External server: which is a server for various application APP, etc., and may provide SMO with rich data.
The O-RAN architecture mainly includes four interfaces:
A1: which is located between Non-RT RIC and near-RT RIC, and supports strategy management, rich information and ML model management services.
E2: which is used to connect the near-RT RIC and E2 node. One E2 node can only be connected to one near-RT RIC. The Near-RT RIC entity can collect the near-real-time information (UE-level or cell-level) measured by respective functional entity of the wireless network through the E2 interface, and can also issue control command words to the base station through the E2 interface, and finally the E2 interface may control the behavior of the base station.
O1: which is an interface located between the O-RAN managed entity (near-RT RIC, E2 node) and the O-RAN management entity (SMO), and supports operation and management, including network fault/configuration/accounting/performance/security (FCAPS) management, physical network function (PNF) software management and file management.
O2: which connects SMO and O-Cloud to support O-RAN virtualization.
Open fronthaul M-plane interface: which is located between SMO and O-RAN radio unit (O-RU) to support O-RU management.
In order to make the objectives, technical solutions, and advantages of the present disclosure clear, the implementations of the present disclosure will be further described in detail below in conjunction with the accompanying drawings.
To support large-scale connections, 3GPP has proposed two cellular IoT protocol standards of Narrow Band IOT (NB-IoT) and enhanced machine type communication (eMTC). In the protocol, 3GPP introduced the concept of coverage level (CL). As shown in FIG. 1, CL is divided by defining a signal strength threshold (rsrpThreshold), and differentiated resource configurations are defined for respective coverage levels to achieve requirements of coverage, capacity, and management for a large number of terminals.
CL division is mainly achieved by defining reference signal receiving power (RSRP) threshold. In actual networks, the RSRP threshold is generally determined based on the maximum and deepest coverage of the cell. However, since IoT services are mostly transmitted infrequently, in fact, the distribution of IoT terminals that truly have service transmitting and receiving requirements in the cell has time-varying characteristics. As shown in FIG. 2 and FIG. 3, for example, IoT terminals are distributed evenly during the day, but at night, most of the terminals that transmit IoT services fall into a range of strong signal strength. In this case, a fixed division of three CLs and a fixed resource configuration may lead to insufficient resources for CL0, which may cause access congestion; at the same time, the resources reserved for CL1 and CL2 may be wasted since the actual number of users is small, thereby reducing resource utilization.
(2) The semi-static resource configuration cannot adapt to the time-varying distribution of IoT terminals, which results in an increased power consumption and a decreased system capacity.
As above mentioned, the distribution of IoT terminals that truly have service transmitting and receiving requirements in the cell has time-varying characteristics. The CL-based semi-static resource configuration cannot adapt to the time-varying characteristics of terminal distribution, and may allocate a larger number of repetitions, which not only wastes terminal power, but also causes unnecessary resource waste, thereby reducing system capacity.
As shown in FIG. 4, during the morning time period, an actual effective terminal of CL0 in the area is UE1/UE2; during the noon time period, the actual effective terminal of CL0 is UE1/UE5; during the afternoon time period, the actual effective terminal of CL0 is UE1/UE2. Where, UE1/UE5 have higher RSRP, it may meet transmission requirement that the number of repetitions is 1; UE2 has lower RSRP, and the number of repetitions is 2. In this case, if it uses the semi-static configuration that the number of repetitions is 2, the number of repetitions for UE1 and UE5 would be too high during the noon time period, which results in an increased resource occupation.

Optionally, in step 5, it may use the predicted IoT service terminal distribution under respective RSRPs obtained in step 4 to cluster RSRP thresholds of different coverage levels.
Optionally, based on obtained the RSRP thresholds, it is possible to calculate the number of repetitions of PDCCH/PDSCH/PUSCH/UCI (uplink control information) and MCS (modulation and coding scheme) configuration of the IoT terminal under respective CLs.
Specifically: the adjusting of the number of repetitions for transmission of the physical downlink control channel may include adjusting the number of repetitions of message msg2, message msg3, and message msg4 in the common search space, and the number of repetitions of the dedicated search space.

Step 6: the calculation and control unit may transmit the optimized radio resources and transmission parameters to the network device, and the network device performs the parameter updating and configuration.
Optionally, for step 4, the calculation and control unit may use at least one of an artificial intelligence (AI) model and a machine learning ML model to predict the service distribution in the next time period, which involves using historical data (for example, data from the past year) to train the AI model, and the distribution of the IOT service capacity over time under different RSRPs in the next period is predicted based on the distribution characteristics of the most recent N (>=1) periods. For example, the predicted requirement capacity distribution under the ith RSRP in the next period T is as the following formula (1):
Capacity_RSRPi(t) ( 0< t <T) (1)
Optionally, for step 5, the calculation and control unit may form optimized wireless resources and transmission parameters based on the predicted IoT service terminal distribution, which specifically includes the following steps.
Step 5-1: estimating the classification configuration parameters of the CL in the system, which include the RSRP threshold and the number of CLs.
Based on the predicted IoT service terminal distribution, the method of variance analysis is used to obtain the number of coverage levels and the corresponding RSRP threshold.
Step 1: based on the AI prediction result obtained in step 4, a formula (2) is used to calculate the sum of capacity requirements under the ith RSRP within the prediction period T, formula (2) is as follows:
Capacity_RSRPi (T)= ²TCapacity_RSRPi(t) (2)
Then, the distribution of the required capacity within the period T is obtained. As shown in FIG. 8, the X-axis represents RSRP value, and the Y-axis represents the capacity corresponding to respective RSRPs within the prediction period T.
Step 2: as shown in FIG. 9, through a sliding window, the RSRP distribution range within the period T is divided into m regions. The set number of sliding windows depends on the maximum number of coverage levels supported by the system. If the maximum number of coverage levels supported by the system is M (for example, which is 3 in the current NBIOT system, 3 is taken as an example for analysis in this case), then M-1 sliding windows are used for division, and m=1~M.
Step 3: variance analysis is performed on the m divided regions obtained by each sliding of the sliding window in step 2, as shown in FIG. 10, it may perform corresponding weighting processing by taking into account the influence of capacity distribution, the weighted variance for the ith region is the following formula (3):

Step 4: values for RSRP TH1&TH2&...&THM-1 are selected so that the discrete variance corresponding to the system is the smallest in the divided area, as shown in formula (4), formula (4) represents the minimum value for the sum of M weighted variances.
Figure PCTKR2021009111-appb-I000002
(4)
Step 5: based on the values for RSRP TH1&TH2&...&THM-1 obtained in Step 4, obtaining the system configuration of the RSRP threshold.
Optionally, NB-IoT supports up to 3 coverage levels.
The RSRP TH1&TH2 values obtained in step 4 may be divided into three situations as shown in FIG. 11-a, 11-b and 11-c.
As shown in FIG. 11-a, when TH1=RSRPmax and TH2=RSRPmin, the variance is smallest, then it may be considered that the RSRP distribution of all IoT terminals has the smallest variance under the condition of not dividing the range, so there is no need to configure RSRP thresholds, and the cell has only 1 coverage level.
As shown in FIG. 11-b, when TH2=RSRPmin, TH1!=RSRPmin, the variance is smallest, then it may be determined that it only needs to configure one threshold of TH1, and the cell is divided into 2 coverage levels.
As shown in FIG. 11-c, when TH2!=RSRPmin, TH1!=TH2, and TH1! =RSRPmax, the variance is smallest, then it may be determined that the thresholds are TH1 and TH2, and the cell is divided into 3 coverage levels.
Step 5-2-1: calculating the configuration of data parameters under different CLs, including the number of repetitions for transmission and the MCS value.
Step 1: estimating the distribution of the minimum RSRP value of IOT services in different CL ranges over time. Based on the RSRP threshold obtained above, the range of RSRP values in different CLs in the next period may be obtained.
Optionally, as shown in FIG. 12, the AI-based prediction may obtain the capacity requirement distribution under respective RSRPs, as shown in formula (1):
Capacity_RSRPi(t) (0< t <T)
Optionally, when Capacity_RSRPi(t1)=0 or Capacity_RSRPi(t1) < Capacity_Threshold, then at time t1, the probability of IOT services occurring under RSRPi is zero (or very small), and there will be no data transmission, then the probability of corresponding RSRP existing is 0, otherwise the probability of corresponding RSRP existing is 1.
Optionally, through the analysis of all RSRPs in the CL range at each time t within the time period T, the RSRP set with the probability of all RSRPs existing in the CL range is obtained, and then at each time t in the period T, the minimum RSRP value corresponding to the system is obtained, which refers to the distribution of the minimum RSRP value in CL over time.
Optionally, as shown in FIG. 13, the distribution of the minimum RSRP value under respective CLs of the system over time may be obtained.
Step 2: analyzing the fluctuation features of the minimum RSRPmin(t) value over time in respective CLs. The calculation duration is the minimum RSRP change in the two time periods t1 and t2 before and after td1 and td2, respectively, as shown in formula (5):
RSRP= RSRPmin(t2) - RSRPmin(t1) (5)
Step 3: based on RSRP, estimating the change in the number of data retransmissions and MCS configuration within the time period t2. The change in the number of repetitions is defined as Rep, and the change in code modulation is defined as △MCS. A possible related algorithm is shown in FIG. 14, where X, Y, and Z values depend on the performance of the device and can be pre-configured.
The RSRP obtained in S301 is rounded to obtain an integer difference.
S302: determining whether RSRP is not less than XdB; when △RSRP is not less than XdB, the change in the number of repetitions for transmission is as follows:
S303,△Rep=floor(△RSRP/X).
After adjusting the number of repetitions, the difference of remaining RSRPs is as follows:
S304, △RSRPr=△RSRP-X*△Rep;
S305, determining whether △RSRPr is greater than YdB; when △RSRPr is less than YdB, then S309, MCS configuration will not be changed: △MCS=0; when △RSRPr is greater than YdB, then S306;
S306, determining whether △RSRPr is greater than ZdB; when △RSRPr is greater than YdB but less than ZdB, then S307, MCS configuration change is: △MCS=1; when △RSRPr is greater than ZdB, then S308, MCS configuration change is: △MCS=2;
S302, determining whether RSRP is not less than XdB; if △RSRP is less than XdB, the number of repetitions for transmission does not change, S310 △Rep=0; MCS configuration change is:
S311: determining whether △RSRPr is greater than YdB; when △RSRP is less than YdB, then S312, MCS configuration will not be changed: △MCS=0;
S313: determining whether △RSRPr is greater than ZdB; when △RSRP is greater than YdB but less than ZdB, then S314, MCS configuration change is: △MCS=1; when △RSRP is greater than ZdB, then S315, MCS configuration changes is: △MCS=2.
Step 4: based on the number of data retransmissions RepNum1 and MCS1 in the time period t1, configuring the number of data retransmissions RepNum2 and MCS2 in the time period t2, as shown in formulas (6) and (7):
RepNum2 = RepNum1 + Rep (6)
MCS2 = MCS1 + MCS (7)
Step 5-2-2: calculating the parameter configuration of RACH under different CLs, including the number of repetitions for transmission of random access preamble, the number of subcarriers, and the period.
Step 1: estimating the time-varying distribution of IOT service capacity requirements over time in different CL ranges.
First, according to the RSRP threshold obtained above, the range of RSRP values in different CLs in the next period may be obtained;
The required capacity distribution under respective RSRPs obtained based on AI prediction is shown in formula (1):
Capacity_RSRPi(t) ( 0< t <T)
In the period T, the distribution characteristics of the total required capacity of the IOT service under CLx over time is shown in formula (8):
CapacityCLx_RSRP(t)= Σi Capacity_RSRPi(t) (8)
In this way, the distribution of the capacity requirements of the IOT services under respective CLs of the system over time may be obtained, as shown in FIG. 15.
Step 2: analyzing the fluctuation features of IOT capacity requirement over time in each CL. The calculation duration is the change of the capacity requirement in the two time periods t1 and t2 before and after td1 and td2, respectively, as shown in formula (9):
△Capacity= CapacityCLx_RSRP(t2) - CapacityCLx_RSRP(t1) (9)
Step 3: determining whether to reconfigure RACH resources of CL based on △Capacity. If △Capacity is greater than the threshold △Capacity_Threshold, it is considered that the current IoT capacity increases, and the existing RACH resources cannot meet the access requirements, and RACH resources need to be reconfigured; otherwise, the RACH resource configuration does not change.
Step 4: determining the resource configuration of RACH in CL.
Based on the previously obtained capacity performance reference under different RACH configurations, it may estimate the RACH resource configuration that meets the CapacityCLx_RSRP(t2) capacity requirement in the time period t2, which includes the number of repetitions, the period, and the number of subcarriers.
The capacity performance reference gives the system's access success rate or system's access capacity value under different RACH resource configurations (the number of repetitions, period, the number of subcarriers) and the number of users with access requirements.
According to the estimated required capacity CapacityCLx_RSRP(t2), the configuration that enables the highest system access success rate under the required capacity is selected from the capacity references as the RACH configuration in the time period t2.

FIG. 16-a and FIG. 16-b show a principle flow of information processing under the O-RAN system and the modules and interfaces in the corresponding O-RAN system framework.
As shown in FIG. 16-a and FIG. 16-b: step (1): the SMO module collects the location information of the terminal and the feature information of the IOT service (such as the periodic characteristic of the service) from the application server. The above information is used to realize the estimation and prediction of IOT coverage characteristics and service feature in the cell.
The location of IoT users is mostly static (for example, meter reading service) or the running trajectory is regular (for example, high-voltage power line inspection service). Operators may obtain relevant information from vertical industries and store it in the operation server in advance.
IOT services generally have periodic regularities. For example, the humidity detection service detects and reports the humidity indicators of the surrounding environment every fixed time interval. Operators can also store the relevant requirement information of vertical industries in the operation server in advance.

Step (3): the SMO transmits the received measurements to Non-RT RIC via the internal bus. The Non-RT RIC analyzes the measurement and statistical results, which involves using user BO and vertical industry preset period or time settings to obtain the periodic characteristics of IOT services under the coverage of respective RSRPs, involves using the number of Msg1 and Msg4 received in each CL and the corresponding RACH configuration information to analyze the capacity performance reference under different RACH configurations. This capacity reference gives different RACH configurations (the number of repetitions, period, the number of subcarriers), the access success rate or the access capacity value of the system under any number of users with access requirements.
Step (4): the Non-RT RIC uses AI/ML to predict the service distribution in the next time period, which involves Non-RT RIC using historical data (such as the data of the past year) to train the AI model to obtain an AI model suitable for IoT service in a cell. It involves using the trained AI model in combining with the service period distribution characteristics obtained in step (3) and the actual measurement data in the last N (>=1) periods to predict the distribution of the IOT service capacity over time under different RSRPs in the next period.
Step (5): the Non-RT RIC dynamically configures cell radio resources and transmission parameters based on the distribution characteristics of IOT services in the cell, which includes clustering IOT terminals in the same cell by using the capacity weighted variance analysis method, which is realized particularly through estimating and setting different RSRP thresholds. Further, for IOT users in the same cluster, the fluctuation features of the coverage characteristics over time are estimated, and the number of repetitions required for data transmission and the change of MCS are dynamically estimated based on the fluctuation features, so as to obtain the number of repetitions of data transmission and the optimal configuration of MCS for the same type of IOT users in different time periods. On the other hand, in order to ensure the access performance of the same type of IOT users, it may estimate the capacity requirement distribution of the same type of user IOT services in different time periods, and use the capacity performance reference under different RACH configurations obtained in step (3) to estimate the best RACH resource and transmission parameter configuration in different time periods (including the number of RACH subcarriers, period, and the number of repetitions).
Step (6): it may transmit the resource and transmission parameter configuration obtained in step (5) to SMO through the internal bus interface Non-RT RIC. Next, SMO transmits the relevant parameter configuration to the O-eNB or O-DU by using the O1 interface. Finally, the O-eNB or O-DU completes the update of resource configuration parameters.

And the Non-RT RIC uses the trained AI model in combining with the service period distribution characteristics obtained in step (3.1) and the actual measurement data collected in step (2.1) in the last N (>=1) periods to predict the distribution of the IOT service capacity over time under different RSRPs in the next period.

Step (5): the Non-RT RIC dynamically configures cell radio resources and transmission parameters based on the distribution characteristics of IOT services in the cell, which includes clustering IOT terminals in the same cell by using the capacity weighted variance analysis method, which is realized particularly through estimating and setting different RSRP thresholds. Further, for IOT users in the same cluster, the fluctuation features of the coverage characteristics over time are estimated, and the number of repetitions required for data transmission and the change of MCS are dynamically estimated based on the fluctuation features, so as to obtain the number of repetitions of data transmission and the optimal configuration of MCS for the same type of IOT users in different time periods.

The above information is used to realize the estimation and prediction of IOT coverage characteristics and service characteristics in the cell.
The location of IoT users is mostly static (for example, meter reading service) or the running trajectory is regular (for example, high-voltage power line inspection service). Operators may obtain relevant information from vertical industries and store it in the operation server in advance.
IOT services generally have periodic regularities. For example, the humidity detection service detects and reports the humidity indicators of the surrounding environment every fixed time interval. Operators can also store the relevant requirement information of vertical industries in the operation server in advance.

The Non-RT RIC analyzes the measurement and statistical results, which involves using user BO and vertical industry preset period or time settings to obtain the periodic characteristics of IOT services under the coverage of respective RSRPs, involves using the number of Msg1 and Msg4 received in each CL and the corresponding RACH configuration information to analyze the capacity performance reference under different RACH configurations. This capacity reference gives different RACH configurations (the number of repetitions, period, the number of subcarriers), the access success rate or the access capacity value of the system under any number of users with access requirements.
Step (3.2): the Non-RT RIC transfers the analyzed period characteristics of IOT services under the coverage of each RSRP and the capacity performance reference results under different RACH configurations to Near-RT RIC through the A1 interface.
Step (4.1): the Non-RT RIC uses long-term historical data (such as the data of the past year) to train the AI model to obtain an AI model suitable for the IOT service in the cell.
Step (4.2): the Non-RT RIC deploys the trained AI model suitable for the IOT service to the Near-RT RIC through the O1 interface.
Step (4.3): the Near-RT RIC uses the AI/ML model to predict the service distribution in the next time period, which involves using the trained AI model in combining with the service period distribution characteristics obtained in step (3.2) and the actual measurement data in the last N (>=1) periods to predict the distribution of the IOT service capacity over time under different RSRPs in the next period.
Step (5): the Non-RT RIC dynamically configures cell radio resources and transmission parameters based on the distribution characteristics of IOT services in the cell, which includes clustering IOT terminals in the same cell by using the capacity weighted variance analysis method, which is realized particularly through estimating and setting different RSRP thresholds. Further, for IOT users in the same cluster, the fluctuation features of the coverage characteristics over time are estimated, and the number of repetitions required for data transmission and the change of MCS are dynamically estimated based on the fluctuation features, so as to obtain the number of repetitions of data transmission and the optimal configuration of MCS for the same type of IOT users in different time periods. On the other hand, in order to ensure the access performance of the same type of IOT users, it may estimate the capacity requirement distribution of the same type of user IOT services in different time periods, and use the capacity performance reference under different RACH configurations obtained in step (3.2) to estimate the best RACH resource and transmission parameter configuration in different time periods (including the number of RACH subcarriers, period, and the number of repetitions).
