Description

Technical Field

[0001] The present application relates to the field of wireless communication technologies, and particularly to a service expansion method, apparatus, communication device, and computer-readable storage medium. Background Art

[0002] Reduced Capability (RedCap) is a lightweight technology for 5G terminals. This technology reduces the complexity and power consumption of devices by trimming the capabilities of 5G terminals, thereby enabling the large-scale application of 5G terminals in technologies such as the Internet of Things. Currently, the bandwidth of the new radio (NR) in the 3.5G frequency band is usually 100 MHz, and RedCap can support a maximum bandwidth part (BWP) of 20 MHz. By configuring a section of bandwidth within the NR frequency band for RedCap to use, the deployment of RedCap in the 5G network can be achieved.

[0003] Considering resource utilization as the expansion metric for RedCap, according to traditional technologies, the statistical method of resource utilization is to calculate the proportion of physical resource blocks (PRBs) occupied by RedCap in the entire NR bandwidth. When the resource utilization of RedCap is relatively high, from the perspective of the entire NR bandwidth, if the traffic volume of ordinary NR users is small, the resource utilization of the entire system is not high either. In this case, the expansion standard may not be met, resulting in the neglect of the expansion requirements for RedCap.

[0047] In order to make the objectives, technical solutions, and advantages of the present application clearer, the following further describes the present application in detail with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0048] It should be noted that the terms "first", "second", etc. in the specification, claims and the above-mentioned drawings of the present disclosure are used to distinguish similar objects, and do not necessarily have to be used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present disclosure described herein can be implemented in an order other than those illustrated or described herein. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0049] With the rapid development of Internet of Things (IoT) requirements, scenarios such as Enhanced Mobile Broadband (eMBB) and Massive Machine Type Communication (mMTC) have raised the requirements for the performance of 5G terminals. To solve this problem, the 3GPP R17 standardizes the RedCap technology, aiming to reduce capabilities, costs, and power consumption by trimming the terminal hardware, so that 5G technology can be widely applied in scenarios such as video surveillance, industrial sensing, and personal wearables. 3GPP R17 specifies that RedCap supports a maximum Bandwidth Part (BWP) bandwidth of 20 MHz, with antenna trimming to 1T1R / 1T2R, and defines basic features such as residence, identification, access, and mobility, as well as features such as energy saving, Small Data Transmission (SDT), and coverage enhancement. At the same time, it also supports 5G native functions such as slicing, Ultra Reliable and Low Latency Communication (uRLLC), and 5G Local Area Network.

[0050] The 5G radio network channels can be divided into two cases: restricted and unrestricted. Among them, the unrestricted channels include:

[0051] (1) Primary Synchronization Signal (PSS) / Secondary Synchronization Signal (SSS), Physical Broadcast Channel (PBCH): They occupy fixed time-frequency positions and resources, are broadcast-type channels, do not need to consider capacity issues, nor the restrictive relationships with other channels;

[0052] (2) Physical Random Access Channel (PRACH), Physical Uplink Control Channel (PUCCH), Sounding Reference Signal (SRS): The capacity can be increased or decreased through the configuration of the channel itself. Therefore, there is no capacity limitation, but it will restrict the available time-frequency resources of other channels.

[0053] The restricted channels include:

[0054] (1) Physical Downlink Control Channel (PDCCH): The available time-frequency resources come from the remaining resources after the reference signal allocation. As the control information and the number of users increase, the channel capacity will be limited.

[0055] (2) Physical Downlink Shared Channel (PDSCH): Transmits downlink service information. As the traffic volume increases, the capacity will be limited.

[0056] (3) Physical Uplink Shared Channel (PUSCH): The available time-frequency resources come from the remaining resources after the PUCCH and PRACH allocations. It transmits uplink service information. As the traffic volume increases, the capacity will be limited.

[0057] Among them, the restricted channels can be further divided into the common channel PDCCH, and the service channels PDSCH and PUSCH. Among them, for the common channel, the resource utilization and the number of users should be comprehensively considered. When occupying 3 symbols, the resource utilization rate of PDCCH is usually not greater than 70% (different operators may set different thresholds); for the service channels, it is the maximum resource utilization rate that the system can carry under the condition of meeting network assessment indicators such as access success rate, disconnection rate, and congestion rate. The resource utilization rate can be tentatively set at 70% in the initial stage of network construction (different operators may set different thresholds). When considering the system expansion index, usually the restricted channels of the system are considered. This application mainly focuses on the resource utilization rate of the service channels in the restricted channels. When calculating the resource utilization rate, considering that both the 5G uplink and downlink service channels are scheduled in units of PRB, the PRB occupancy rate can be used to evaluate the system resource utilization rate.

[0058] 3GPP R17 specifies that the maximum BWP bandwidth supported by RedCap is 20 MHz, and the bandwidth of the 3.5G NR band is 100 MHz. By configuring a BWP with a bandwidth of 20 MHz within the NR band for RedCap to use, the deployment of RedCap in the 5G network can be achieved. Since RedCap is included within the NR bandwidth and only occupies the PRBs within the configured BWP, while ordinary NR terminals can use the PRBs within 100 MHz, when the PRB occupancy rate of RedCap is very high, for the entire bandwidth, if the traffic volume of ordinary NR users is small, the statistical value of the PRB occupancy rate of the entire system will not be high, which may lead to the neglect of the expansion requirements of RedCap.

[0059] Figure 1 The schematic diagram of the expansion index statistics after RedCap deployment is provided. Among them, CD-SSB is the Cell Defining Synchronization Signal and PBCH block, and NCD-SSB is the Non Cell Defining Synchronization Signaland PBCH block. Refer to Figure 1 , currently, no distinction is made between the PRB resources used by RedCap UEs (User Equipment) and NR UEs, and they are statistically mixed together. In this case, for the situation where the RedCap and NR bandwidths are equal, the resource utilization rate of RedCap can be accurately reflected. However, for the situation where the RedCap and NR bandwidths are not equal, the resource utilization rate of RedCap cannot be accurately statistically calculated. For example, in the 3.5G band, the NR bandwidth is 100 MHz, and the BWP bandwidth of RedCap is 20 MHz. If the PRB occupancy rate of RedCap within the 20 MHz bandwidth is 80%, and the PRB occupancy rate of NR within the 100 MHz bandwidth is 30%, at this time, the RedCap resource utilization rate is relatively high, and it can be determined that RedCap needs to be expanded. However, when the resources of RedCap and NR are statistically mixed together, what is statistically calculated is the total PRB occupancy rate of RedCap and NR within the 100 MHz bandwidth. At this time, the total PRB occupancy rate may be obtained as 40%, which has not reached the expansion standard, so RedCap will not be expanded. Based on this, there is a problem of inaccurate expansion index statistics in traditional technologies.

[0060] Based on the above traditional technologies, embodiments of the present application provide a service expansion method. By obtaining the resource occupancy corresponding to the service type, and based on the resource occupancy and the total available resources of the service type, the resource utilization rate of the service type is obtained. According to the resource utilization rate, expansion processing is performed on the service type; the resource utilization rate of the service type can be determined based on the resource occupancy and the total available resources of the service type, and expansion metrics are statistically calculated for the service type, increasing the accuracy of the expansion metrics, thereby accurately identifying service expansion requirements and avoiding the neglect of expansion requirements.

[0061] It should be noted that the beneficial effects brought by the embodiments of the present application or the technical problems solved are not limited to this one, and there may also be other implicit or related problems. For specific details, please refer to the descriptions in the following embodiments.

[0062] The following uses specific embodiments to elaborate in detail on the technical solutions of the present application and how the technical solutions of the present application solve the above technical problems. These several specific embodiments can be combined with each other, and for the same or similar concepts or processes, they may not be repeated in some embodiments. The following will describe the embodiments of the present application in conjunction with the accompanying drawings.

[0063] In an exemplary embodiment, as Figure 2 shown, a service expansion method is provided. In this embodiment, it is exemplified that the method is applied to a base station. It can be understood that the method can also be applied to a network management server, and can also be applied to a system including a base station and a network management server, and is implemented through the interaction between the base station and the network management server. In this embodiment, the method includes the following steps:

[0064] Step S102, obtain the resource occupancy corresponding to the service type.

[0065] Among them, the service type can be a wireless communication service type, including but not limited to RedCap, eMBB, uRLLC, mMTC, NR, etc. The resource occupancy can be the number of occupied PRBs.

[0066] In specific implementation, the base station can count the number of PRBs occupied by a specified service type to obtain the resource occupancy corresponding to the service type.

[0067] For example, the base station can measure the number of PRBs occupied by all RedCap UEs on the current cell's PDSCH channel to obtain the resource occupancy of the RedCap downlink service channel; it can also measure the total number of PRBs occupied by the current cell's PUCCH, PRACH, and PUSCH channels to obtain the resource occupancy of the RedCap uplink channel.

[0068] Step S104, obtain the resource utilization rate of the service type according to the resource occupancy and the total available resources of the service type.

[0069] Among them, the total available resources can be the total number of PRBs that can be used. The resource utilization rate is the resource utilization of a specified service type and can be used as an expansion indicator for this service type.

[0070] In a specific implementation, the base station can calculate the proportion of the resource occupancy in the total available resources of the specified service type and use this proportion as the resource utilization rate of the specified service type.

[0071] For example, if the resource occupancy of the RedCap downlink service channel is measured as a PRBs, the RedCap downlink bandwidth is 20 MHz, and the corresponding total available resources are A PRBs, then the resource utilization rate of the RedCap downlink service channel is a / A×100%; if the resource occupancy of the RedCap uplink channel is measured as b PRBs and the total available uplink resources are B PRBs, then the resource utilization rate of the RedCap uplink channel is b / B×100%.

[0072] Step S106: Perform an expansion process on the service type according to the resource utilization rate.

[0073] Among them, the expansion process can, but is not limited to, increasing the total available resources of the service type.

[0074] In a specific implementation, if the calculated resource utilization rate exceeds a preset threshold, it indicates that the capacity of the specified service type is limited, and the base station can perform an expansion process on this service type. Otherwise, if the calculated resource utilization rate does not exceed the preset threshold, the base station does not need to perform an expansion process on this service type.

[0075] For example, when a / A×100%>T1, the capacity of the RedCap downlink service channel is limited, and at this time, the total available resources of the RedCap downlink service channel can be increased; when b / B×100%>T2, the capacity of the RedCap uplink channel is limited, and at this time, the total available resources of the RedCap uplink channel can be increased. Among them, T1 and T2 are both resource utilization rate thresholds.

[0076] It should be noted that although this application focuses on the resource utilization rate of the service channel, the methods in the embodiments of this application are not limited to being applied to the service channel and can also be applied to channels such as PDCCH.

[0077] The above service capacity expansion method obtains the resource occupancy corresponding to the service type, calculates the resource utilization rate of the service type based on the resource occupancy and the total available resources of the service type, and performs capacity expansion processing on the service type according to the resource utilization rate; it can determine the resource utilization rate of the service type based on the resource occupancy and the total available resources of the service type, count the capacity expansion metrics for the service type, improve the accuracy of the capacity expansion metrics, thereby accurately identifying the service capacity expansion requirements and avoiding the neglect of capacity expansion requirements.

[0078] In an exemplary embodiment, the above step S104 may specifically include: obtaining the resource utilization rate of the service type based on the resource occupancy of the service type in the downlink service channel and the total available downlink resources of the service type.

[0079] Among them, the downlink service channel may be a PDSCH channel. The total available downlink resources may be the total number of PRBs that can be used in the downlink.

[0080] In specific implementation, the base station may measure the resource occupancy of the downlink service channel for a specified service type, and obtain the resource utilization rate of the service type based on the proportion of the resource occupancy in the total available downlink resources of the service type.

[0081] For example, when the cell covers multiple types of UEs such as RedCap UE and NR UE, it is possible to measure the number of PRBs occupied by all RedCap UEs in the PDSCH channel to obtain the resource occupancy PDSCH PRB.Occupancy.classRedCap. Let the total number of PRBs available for RedCap downlink be PRB DL Total, then the resource utilization rate of the RedCap downlink service channel is PDSCHPRB.Occupancy.classRedCap / PRB DL Total×100%.

[0082] In this embodiment, by obtaining the resource utilization rate of the service type based on the resource occupancy of the service type in the downlink service channel and the total available downlink resources of the service type, it is possible to accurately count the resource utilization rate of the downlink service channel and improve the accuracy of the capacity expansion metrics for the downlink service channel.

[0083] In an exemplary embodiment, the above step S104 may specifically include: determining the resource occupancy based on the first occupancy of the service type in the uplink control channel, the second occupancy of the service type in the uplink service channel, and the third occupancy of the service type in the random access channel; obtaining the resource utilization rate of the service type based on the resource occupancy and the total available uplink resources of the service type.

[0084] Among them, the uplink control channel can be a PUCCH channel. The first occupancy can be the number of PRBs occupied by the PUCCH channel. The uplink traffic channel can be a PUSCH channel. The second occupancy can be the number of PRBs occupied by the PUSCH channel. The random access channel can be a PRACH channel. The third occupancy can be the number of PRBs occupied by the PRACH channel. The total available uplink resources can be the total number of PRBs that can be used on the uplink.

[0085] In a specific implementation, the base station can measure the first occupancy of its PUCCH channel, the second occupancy of the PUSCH channel, and the third occupancy of the PRACH channel for a specified service type, and calculate the sum of the first occupancy, the second occupancy, and the third occupancy to obtain the total uplink resource occupancy. Then, based on the proportion of the resource occupancy in the total available uplink resources of the service type, the resource utilization rate of the service type can be obtained.

[0086] For example, the number of PRBs occupied by the PUCCH, PUSCH, and PRACH channels can be measured respectively to obtain the resource occupancies PUCCH PRB.Occupancy.classRedCap, PUSCH PRB.Occupancy.classRedCap, and PRACH PRB.Occupancy.classRedCap. Assuming that the total number of PRBs available for RedCap uplink is PRB UL Total, the RedCap uplink resource utilization rate is (PUCCH PRB.Occupancy.classRedCap + PUSCH PRB.Occupancy.classRedCap + PRACH PRB.Occupancy.classRedCap) / PRB UL Total×100%.

[0087] In this embodiment, by determining the resource occupancy based on the first occupancy of the uplink control channel, the second occupancy of the uplink traffic channel, and the third occupancy of the random access channel for the service type, and obtaining the resource utilization rate of the service type based on the resource occupancy and the total available uplink resources of the service type, the uplink resource utilization rate can be accurately counted, and the accuracy of the uplink capacity expansion index can be improved.

[0088] In an exemplary embodiment, the above step S106 can specifically include: determining whether the service type is capacity - limited according to the resource utilization rate; and increasing the total available resources of the service type when it is determined that the service type is capacity - limited.

[0089] In a specific implementation, the base station can compare the resource utilization rate with a preset threshold. If the resource utilization rate exceeds the preset threshold, it is determined that the capacity of the corresponding service type is limited, and then the total available resources of this service type can be increased. Otherwise, if the resource utilization rate does not exceed the preset threshold, it can be determined that the capacity of the corresponding service type is not limited, and there is no need to increase the total available resources of this service type at this time.

[0090] For example, when the resource utilization rate of the RedCap downlink service channel exceeds the preset threshold T1, the total available resources of the RedCap downlink service channel, PRB DL Total, can be increased; when the resource utilization rate of the RedCap uplink exceeds the preset threshold T2, the total available resources of the RedCap uplink channel, PRB UL Total, can be increased. Among them, both T1 and T2 are resource utilization rate thresholds.

[0091] In this embodiment, by determining whether the capacity of the service type is limited according to the resource utilization rate, and increasing the total available resources of the service type when it is determined that the capacity of the service type is limited, the expansion can be carried out when the expansion index reaches the expansion standard, ensuring the reliable execution of the service.

[0092] In an exemplary embodiment, the above step S102 may specifically include: measuring the number of physical resource blocks occupied by the service type; obtaining the resource occupancy according to the number of physical resource blocks.

[0093] In a specific implementation, the base station can measure the number of PRBs occupied by a specified service type and determine the resource occupancy of this service type according to the measured number of PRBs.

[0094] For example, the number of PRBs occupied by all RedCap UEs on the PDSCH channel can be measured to obtain the resource occupancy of the RedCap downlink service channel, PDSCH PRB.Occupancy.classRedCap; the number of PRBs occupied by the PUCCH, PUSCH, and PRACH channels can also be measured respectively to obtain the resource occupancies PUCCH PRB.Occupancy.classRedCap, PUSCHPRB.Occupancy.classRedCap, and PRACH PRB.Occupancy.classRedCap, and PUCCHPRB.Occupancy.classRedCap + PUSCH PRB.Occupancy.classRedCap + PRACHPRB.Occupancy.classRedCap is used as the RedCap uplink resource occupancy.

[0095] In this embodiment, by measuring the number of physical resource blocks occupied by the service type and obtaining the resource occupancy based on the number of physical resource blocks, the resource occupancy can be accurately counted, and then the resource utilization rate can be accurately calculated.

[0096] In an exemplary embodiment, the step of measuring the number of physical resource blocks occupied by the service type may specifically include: measuring the number of physical resource blocks according to a pre-set resource scheduling period.

[0097] Among them, the resource scheduling period may be the period for the 5G network to perform resource scheduling. For example, a radio subframe (1 ms).

[0098] In a specific implementation, the base station may use the resource scheduling period as the statistical period to measure the number of physical resource blocks and obtain the resource occupancy of the specified service type.

[0099] For example, the number of PRBs occupied by the RedCap downlink service channel or the number of PRBs occupied by the uplink channel may be counted in each radio subframe.

[0100] In this embodiment, by measuring the number of physical resource blocks according to a pre-set resource scheduling period, the expansion index can be measured in real time to ensure the real-time nature of service expansion.

[0101] In an exemplary embodiment, the above service type includes at least one of the reduced-capability RedCap service, enhanced mobile broadband eMBB service, ultra-reliable low-latency uRLLC service, massive machine type communication mMTC service, and new radio NR service.

[0102] In a specific implementation, the base station can separately count the resource utilization rates of services such as RedCap, eMBB, uRLLC, mMTC, and NR to obtain accurate expansion indexes.

[0103] In this embodiment, by including at least one of the RedCap service, eMBB service, uRLLC service, mMTC service, and NR service in the service type, accurate expansion indexes for different services can be obtained respectively, and the expansion requirements for different services can be reliably realized.

[0104] To facilitate those skilled in the art to deeply understand the embodiments of the present application, the following will be described with a specific example.

[0105] In one embodiment, three metrics, namely the PDCCH channel utilization rate, the PDSCH channel utilization rate, and the uplink channel utilization rate, can be used to evaluate the utilization of 5G network resources. Among them, the PDCCH channel utilization rate is used to evaluate and analyze the usage of the downlink control channel, the PDSCH channel utilization rate is used to evaluate and analyze the usage of the downlink service channel, and the uplink channel utilization rate is used to evaluate and analyze the usage of the uplink channel resources.

[0106] Specifically, the PDSCH channel resource utilization rate = the number of PRBs actually used in the downlink / the number of available PRBs in the downlink × 100%;

[0107] The uplink channel utilization rate = (the number of PRBs occupied by PUCCH + the number of PRBs occupied by PRACH + the number of PRBs occupied by PUSCH) / the total number of uplink PRBs;

[0108] Among them, the number of PRBs actually used in the downlink can be the number of PRBs actually used in the downlink statistically with a radio subframe (1 ms) as the period, that is, the number of PRBs scheduled for transmitting PDSCH services; the total number of uplink PRBs can be understood as the number of available PRBs in the uplink, and the total number of available PRBs for both the uplink and downlink is related to the system bandwidth.

[0109] In view of the problem that when the resource utilization rates of hybrid statistical RedCap and NR cannot accurately reflect the expansion metrics of RedCap and NR, which is not conducive to network operation and maintenance optimization, this application proposes a RedCap radio resource statistical method. This method can reuse and enhance the existing measurement values related to PRB occupancy defined in the 3GPP standard for this use case. Among them, the current measurements of PRB occupancy include the total number of uplink PRBs occupied in the cell, the total number of downlink PRBs occupied in the cell, the total amount of PUSCH PRB occupancy, the total amount of PDSCH PRB occupancy, etc.

[0110] In one embodiment, in order to accurately evaluate the RedCap air interface resource utilization rate, most aspects of the existing measurements can be reused, and enhanced functions can also be introduced. When a cell covers multiple types of UEs (for example, RedCap UEs, eMBB UEs, eRedCap UEs), the measurement results can be further separated into different subsets to represent the occupancy rates of RedCap PRBs, eMBB PRBs, and eRedCap PRBs.

[0111] Taking the total number of downlink PRBs occupied by a cell as an example, the total PRB occupancy rate can be further divided into different subsets of PRBs, namely PRB.Occupancy.class1, PRB.Occupancy.class2, PRB.Occupancy.class3, …… When classN is RedCap, classN represents the metric of the RedCap PRB occupancy rate, and the subset of classes with RedCap values can be used as the metric of the RedCap PRB occupancy rate.

[0112] Since the measurement results are further separated into different subsets to represent the PRB occupancy rates of different types of terminals such as RedCap UEs, eMBB UEs, and eRedCap UEs, the busy and idle conditions of different services can be accurately evaluated, providing more accurate basic data for network operation and maintenance. The improved resource utilization rate statistical method is as follows:

[0113] (1)RedCap resource utilization rate statistics:

[0114] Resource utilization rate of the PDSCH downlink service channel = PDSCH PRB.Occupancy.classRedCap / Number of available PRBs for RedCap downlink × 100%;

[0115] Uplink resource utilization rate = (Number of PRBs occupied by PUCCH PRB.Occupancy.classRedCap + Number of PRBs occupied by PRACH PRB.Occupancy.classRedCap + Number of PRBs occupied by PUSCH PRB.Occupancy.classRedCap) / Total number of uplink RedCap PRBs × 100%.

[0116] (2)NR resource utilization rate statistics:

[0117] Resource utilization rate of the PDSCH downlink service channel = PDSCH PRB.Occupancy.classNR / Number of available PRBs for downlink × 100%;

[0118] Uplink resource utilization rate = (Number of PRBs occupied by PUCCH PRB.Occupancy.classNR + Number of PRBs occupied by PRACH PRB.Occupancy.classNR + Number of PRBs occupied by PUSCH PRB.Occupancy.classNR) / Total number of uplink PRBs × 100%.

[0119] Through the above mechanism, the RB resources used by RedCap and NR can be separately counted, and the radio resource utilization rates of RedCap and NR can be accurately counted respectively, so as to accurately judge the network loads of RedCap and NR, providing accurate data support for RedCap operation and 5G network operation and maintenance.

[0120] In one embodiment, as Figure 3 shown, a service expansion method is provided, including the following steps:

[0121] Step S201, according to a preset resource scheduling period, measure the number of physical resource blocks occupied by a service type to obtain the resource occupancy corresponding to the service type;

[0122] Step S202, according to the resource occupancy of the service type on the downlink service channel and the total available resources of the service type on the downlink, obtain the resource utilization rate; or,

[0123] Step S203, according to the first occupancy of the service type on the uplink control channel, the second occupancy on the uplink service channel, and the third occupancy on the random access channel, determine the resource occupancy, and according to the resource occupancy and the total available resources of the service type on the uplink, obtain the resource utilization rate;

[0124] Step S204, determine whether the service type is capacity - limited according to the resource utilization rate. When it is determined that the service type is capacity - limited, increase the total available resources of the service type.

[0125] In specific implementation, the base station can measure the number of PRBs occupied by a specified service type in each resource scheduling period to obtain the resource occupancy corresponding to the service type, and obtain the PDSCH channel resource utilization rate according to the ratio of the number of PRBs occupied by the PDSCH channel of the service type to the total available PRBs of the service type on the downlink. Or, count the total number of PRBs occupied by the PUCCH, PUSCH, and PRACH channels of the service type, and obtain the uplink channel resource utilization rate according to the ratio of the total number of PRBs to the total available PRBs of the service type on the uplink. Compare the resource utilization rate with a preset threshold. When the resource utilization rate exceeds the preset threshold, it is determined that the capacity is limited. At this time, the total available resources of the service type can be increased, that is, the total available PRBs on the downlink or the total available PRBs on the uplink of the service type can be increased.

[0126] The above service expansion method can determine the resource utilization rate of a service type according to the resource occupancy and the total available resources of the service type, count the expansion indicators for the service type, increase the accuracy of the expansion indicators, so as to accurately identify the service expansion requirements and avoid the neglect of expansion requirements.
