Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without inventive step based on the embodiments of the present invention, are within the scope of protection of the present invention.

Referring to fig. 1, fig. 1 is a flowchart of a resource allocation method provided in an embodiment of the present invention, for a network device, as shown in fig. 1, the method includes the following steps:

step 101: and performing user pairing on N sliced user groups and M non-sliced users based on the network equipment to determine a user pairing result, wherein N, M are positive integers.

The network device may be a base station or the like, and the resource allocation method may be resource allocation based on MU-MIMO (multi-user-multi-input multi-output), in the MU-MIMO mode, the network device may implement service to a plurality of users, in the MU-MIMO mode, user pairing needs to be performed, one user pairing is to pair two users, and user pairing may also be understood as terminal pairing. In this embodiment, the users of the network device may include N sliced user groups and M non-sliced users, where the sliced user group includes at least one sliced user, and the N sliced user groups and the M non-sliced users may be user-paired by using a pairing algorithm of MU-MIMO, so as to obtain a user pairing result.

Step 102: and determining target resource allocation information of the N slice user groups based on the user pairing result.

After the user pairing is performed, resource allocation information of the N slice user groups is determined according to a user pairing result, and as an example, the resource allocation information may be a resource allocation proportion and the like.

Step 103: and distributing resources for the N slice user groups according to the target resource distribution information of the N slice user groups.

After the target resource allocation information of the N slice user groups is determined, resource allocation can be performed on the N slice user groups according to the target resource allocation information, and it can be understood that time-frequency resource allocation is performed according to the target resource allocation information. In MU-MIMO mode, spatially multiplexed data streams may be scheduled to multiple users, which may share time-frequency resources through spatial multiplexing, whereas in SU-MIMO mode, spatially multiplexed data streams are scheduled to a single user, the time-frequency resources allocated to a user being exclusively owned by that user.

As an example, the time-frequency resources allocated between two users of any pair are the same, and the space-frequency resources allocated are different. Namely, the paired users can adopt the same video resources and different airspace resources to realize space division multiplexing, the sum of the proportion of the resources distributed by the N slice user groups can exceed 100%, and the resource distribution effect is improved.

As shown in fig. 2, in an embodiment, the step 102 of determining target resource allocation information of N slice user groups based on the user pairing result may include:

step 1021: adjusting first resource allocation information of the N slice user groups based on the user pairing result, and determining target resource allocation information of the N slice user groups;

the first resource allocation information is resource allocation information sent by a network slice subnet management function NSSMF, or latest resource allocation information obtained before the current information adjustment is performed on the network device.

That is, before determining target resource allocation information of N slice user groups based on a user pairing result, the network device may receive resource allocation information sent by a network slice subnet management function NSSMF, and if it is determined based on the user pairing result this time that the target resource allocation information of the N slice user groups is the latest resource allocation to the N slice user groups after receiving the resource allocation information sent by the NSSMF, the resource allocation information received from the NSSMF may be adjusted based on the user pairing result, so as to obtain the target resource allocation information. Or, before the resource allocation information is adjusted this time, the resource allocation information has been adjusted last time by the resource allocation method of the present embodiment, so that the latest resource allocation information can be obtained, and the latest resource allocation information can be adjusted based on the user pairing result to obtain the target resource allocation information.

That is, in this embodiment, the resource allocation information sent by the NSSMF may be adjusted, or the latest resource allocation information obtained before the current information adjustment is performed by the network device may be adjusted, so as to adjust the resource allocation information, obtain the target resource allocation information, improve the flexibility of determining the target resource allocation information, allocate resources according to the target resource allocation information, and improve the effect of allocating resources to the slice user groups.

In one embodiment, the user pairing includes at least one of:

pairing in a user group;

pairing among user groups;

pairing of users of the N sliced user groups with M non-sliced users.

Due to the fact that N slice user groups exist, in the user pairing process, at least one pairing mode of in-group pairing, inter-group pairing or pairing of users of the N slice user groups and users of the M non-slice users can be adopted for pairing, so that the pairing of the users of the N slice user groups can be completed, and the flexibility of user pairing can be improved. The user pairing result includes a pairing result of each slice user in the N slice user groups. Intra-group pairing may be understood as pairing users in the same slice user group, and inter-group pairing may be understood as pairing users between slice user groups.

As shown in fig. 3, in an embodiment, the step 101 of determining a user pairing result based on user pairing performed by N sliced user groups and M non-sliced users of a network device includes:

step 1011: determining an ith master user from unpaired slice users of the N slice user groups;

i is an integer, i is more than or equal to 1 and less than N, and N is the total number of slice users of the N slice user groups;

step 1012: determining an ith paired user paired with an ith master user from unpaired users of the first sliced user group under the condition that the unpaired sliced users are included in the first sliced user group;

the first slice user group comprises an ith master user;

and under the condition that each slice user in the N slice user groups is paired, the user pairing result comprises the pairing result of a plurality of main users and the pairing user of the plurality of main users, and the plurality of main users comprise the ith main user.

I can start from 1, i.e. from the determination of the 1 st master user, after aligning and pairing, i can increase by one, and then continue to determine the next master user, and the process is circulated until all users in the N slice user groups are paired, so as to obtain the user pairing result.

In this embodiment, each pairing is to select one master user from unpaired slice users of N slice user groups, and then, intra-slice user group pairing may be preferentially performed, that is, it is determined whether an unpaired slice user other than the master user is included in a first slice user group, where the first slice user group is a slice user group in which the master user is located in the N slice user groups, and if the unpaired slice user other than the master user is included in the first slice user group, a paired user paired with the master user may be determined from the unpaired users of the first slice user group, so that the number of the unpaired users in the N slice user groups is reduced by two after the master user and the paired user are paired.

In one embodiment, after determining the i-th primary user from the unpaired slice users in the N slice user groups, the method further includes:

and under the condition that the first slice user group does not comprise unpaired slice users and the second slice user group comprises unpaired slice users, determining an ith paired user paired with the ith master user from the unpaired slice users of the second slice user group, wherein the first slice user group comprises the ith master user, the N slice user groups comprise the second slice user group, and the second slice user group does not comprise the ith master user.

If the first slice user group does not include unpaired slice users except the ith master user, the slice users in the same slice user group with the ith master user are all paired, an inter-group pairing method can be adopted to pair the ith master user, namely, under the condition that the second slice user group includes unpaired slice users, the ith paired user paired with the ith master user is determined from the unpaired slice users in the second slice user group, and the inter-group user pairing of the ith master user is completed. It should be noted that the second slice user group may be a user group other than the first slice user group in the N slice user groups.

under the condition that a first slicing user group does not comprise unpaired slicing users, a second slicing user group does not comprise unpaired slicing users, and M non-slicing users comprise unpaired users, determining an ith pairing user paired with an ith main user from the M non-slicing users, wherein the first slicing user group comprises the ith main user, the N slicing user groups comprise the second slicing user group, and the second slicing user group does not comprise the ith main user.

If the first sliced user group does not comprise unpaired sliced users except the ith master user and the second sliced user group does not comprise unpaired sliced users, the fact that the users in the N sliced user groups except the ith master user and other sliced users outside the ith master user are all paired is indicated, at the moment, the ith master user can be paired in a pairing mode (namely an intra-group and intra-group pairing mode) of the users in the N sliced user groups and M non-sliced users, a user paired with the ith master user is selected from the M non-sliced users, namely if the M non-sliced users comprise unpaired users, the ith paired user paired with the ith master user can be determined from the M non-sliced users, and the user pairing of the ith master user is completed. It should be noted that, if the first sliced user group does not include unpaired sliced users other than the i-th master user, the second sliced user group does not include unpaired sliced users, and the M non-sliced users do not include unpaired users, that is, the N sliced user groups and the M non-sliced users are all paired, and only the i-th master user is left unpaired, at this time, the i-th master user may not be paired.

In one embodiment, determining an i-th paired user paired with an i-th primary user from unpaired users of a first sliced user group includes:

predicting the predicted cell capacity of the cell to which the ith master user belongs after the unpaired user of the first slice user group is respectively paired with the ith master user;

and selecting the user with the largest predicted cell capacity from the unpaired users of the first slice user group as the ith paired user.

In the process of selecting the ith paired user from the first slice user master, if the number of unpaired users of the first slice user group is one, that is, the number of users capable of being paired with the ith master user in the first slice user group is one, the unpaired users are directly used as the ith paired users, if the number of unpaired slice users of the first slice user group is at least two, that is, the number of slice users capable of being paired with the ith master user in the first slice user group is at least two, one of the slice users needs to be selected as the ith paired user, in the selection process, other factors can be considered as selection conditions for pairing with the ith master user, for example, after the unpaired users of the first slice user group are respectively paired with the ith master user, the predicted cell capacity of the cell to which the ith master user belongs can be predicted firstly, that after the unpaired users of the first slice user group are respectively paired with the ith master user, the cell capacity of the cell to which the ith master user belongs to the first slice user group is predicted respectively paired with the ith master user, that the maximum predicted cell capacity in the unpaired users in the first slice user group is selected as the first slice user, and the first slice user group is preferentially paired with the highest possible to be paired with the first slice user. It should be noted that the cell capacity can be understood as the sum of user rates in a cell.

In one embodiment, determining an i-th paired user paired with an i-th primary user from unpaired slice users of a second slice user group includes:

determining channel orthogonality parameters of unpaired slice users of the second slice user group and the ith main user respectively according to channel information of unpaired slice users of the second slice user group and channel information of the ith main user, wherein the channel orthogonality parameters are used for representing the degree of channel orthogonality;

and selecting the user with the largest orthogonality parameter from the unpaired slicing users in the second slicing user group as the ith pairing user.

It should be noted that the channel orthogonality parameter may be used to indicate a degree of channel orthogonality, and the larger the channel orthogonality parameter is, the larger the degree of channel orthogonality is, and the smaller the channel orthogonality parameter is, the smaller the degree of channel orthogonality is. The greater the channel orthogonality degree is, the less the possibility of interference between channels is, so in this embodiment, in the process of pairing in an inter-group pairing manner, a user with the largest orthogonality parameter may be selected from unpaired slice users of the second slice user group as the ith paired user, that is, a user with large orthogonality is preferentially selected as a paired user of the master user for pairing, which may reduce interference between users, and avoid introducing uncertainty to performance guarantee of the slice user group.

In addition, in the intra-group and intra-group pairing scheme, users with high orthogonality may be selected for pairing, for example, an ith pairing user paired with an ith primary user may be determined from M non-slice users, and the method may include: determining channel orthogonality parameters of the M non-slice users and the ith main user respectively according to the channel information of the M non-slice users and the channel information of the ith main user, wherein the channel orthogonality parameters are used for representing the degree of channel orthogonality; and selecting the user with the largest orthogonality parameter from the M non-slice users as the ith pairing user.

In one embodiment, the adjusting the first resource allocation information of the N slice user groups based on the user pairing result to determine the target resource allocation information of the N slice user groups includes:

determining resource allocation information adjustment amounts of the N slice user groups based on user pairing results, data packet sizes of main users in the N slice user groups in a preset time window and data packet sizes of paired users paired with the main users;

and adjusting the first resource allocation information of the N slice user groups by using the resource allocation information adjustment amount of the N slice user groups, and determining the target resource allocation information of the N slice user groups.

It should be noted that the size of the data packet of the master user in the N slice user groups may be the size of the data packet sent by the master user in the N slice user groups to the network device, may also be the size of the data packet sent by the network device to the master user in the N slice user groups, and may also be the sum of the two sizes. The size of the data packet of the paired user paired with the master user may be the size of the data packet sent by the paired user paired with the master user to the network device, may also be the size of the data packet sent by the network device to the paired user paired with the master user, or may also be the sum of the two. Determining the resource allocation information adjustment amount of the N slice user groups according to the user matching result, the data packet size of a main user in the N slice user groups in a preset time window and the data packet size of a matching user matched with the main user, and adjusting the first resource allocation information of the N slice user groups by using the resource allocation information adjustment amount of the N slice user groups so as to determine the target resource allocation information of the N slice user groups. In this embodiment, the resource allocation information adjustment amount of the N slice user groups may be determined by using the user pairing result, the data packet size of the main user in the N slice user groups within the preset time window, and the data packet size of the paired user paired with the main user, and then the first resource allocation information of the N slice user groups may be adjusted by using the resource allocation information adjustment amount of the N slice user groups, so as to determine the target resource allocation information of the N slice user groups, which may improve the accuracy of the target resource allocation information, thereby improving the resource allocation effect.

In one embodiment, the resource allocation information adjustment amount of the N slice user groups is determined based on the user pairing result and the data packet size of the primary user and the data packet size of the paired user paired with the primary user in the N slice user groups within the preset time window, and includes at least one of the following:

determining the reduction amount of first resource allocation information of a first target slice user group based on first resource allocation information of the first target slice user group, the size of a data packet of the first master user in a preset time window and the size of a data packet of a first paired user under the condition that the first target slice user group comprises a first master user and the first paired user which are paired in the group, wherein the first target slice user is any one of N slice user groups;

determining a first resource allocation information promoting amount of a first target slice user group based on first resource allocation information of the first target slice user group and a data packet size of a second main user in a preset time window under the condition that the first target slice user group comprises the second main user, and determining a second resource allocation information reducing amount of a second target slice user group based on the first resource allocation information of the second target slice user group and the data packet size of a second paired user in the preset time window, wherein the second main user is paired with the second paired user, the second paired user belongs to the second target slice user group, and the N slice user groups comprise second target slice groups;

determining the reduction amount of third resource allocation information of the first target slice user group based on the first resource allocation information of the first target slice user group and the size of a data packet of a third paired user in a preset time window under the condition that the first target slice user group comprises the third paired user, wherein a third main user is paired with the third paired user, the third main user belongs to the third target slice user group, and the N slice user groups comprise third target slice groups;

and under the condition that the first target slice user group comprises a fourth master user paired with a non-slice user, determining the reduction amount of the fourth resource allocation information of the first target slice user group based on the first resource allocation information of the first target slice user group and the data packet size of the fourth master user in a preset time window.

It is to be understood that the first target slice user group is a different user group than the second target slice user group, and the third target slice user group is also a different user group. In the process of determining the adjustment amount of the resource allocation information, for any slice user group of the N slice user groups, if a paired master user and a paired user are included, that is, if the slice user group includes users paired in an intra-group pairing manner, a first resource allocation information reduction amount of a first target slice user group may be determined according to first resource allocation information of the first target slice user group, a size of a data packet of the first master user within a preset time window, and a size of a data packet of the first paired user, and the first resource allocation information reduction amount may be understood as one adjustment amount of the resource allocation information of the slice user group. If the slice user group further includes a second master user, that is, a user who passes through an inter-group pairing mode, a first resource allocation information boost amount of the first target user group may be determined based on the first resource allocation information of the first target slice user group and a data packet size of the second master user within a preset time window, and the first resource allocation information boost amount may be understood as another adjustment amount in the resource allocation information adjustment amount of the slice user group. If the slice user group includes a third paired user, that is, a user including an inter-group pairing mode, a reduction amount of third resource allocation information of the first target slice user group may be determined based on the first resource allocation information of the first target slice user group and a size of a data packet of the third paired user within a preset time window, and the increase amount of the third resource allocation information may be understood as another adjustment amount in the adjustment amount of the resource allocation information of the slice user group. If the slice user group further includes a fourth master user paired with a non-slice user, that is, a user paired in and out of the group, a fourth resource allocation information reduction amount of the first target slice user group may be determined based on the first resource allocation information of the first target slice user group and a data packet size of the fourth master user within a preset time window, and the fourth resource allocation information reduction amount may be understood as a further adjustment amount in the resource allocation information adjustment amounts of the slice user group.

That is, the resource allocation information adjustment amount of any slice user group may include at least one of a first resource allocation information reduction amount, a first resource allocation information promotion amount, a third resource allocation information reduction amount, and a fourth resource allocation information reduction amount, and the first resource allocation information of the slice user group is adjusted by using the resource allocation information adjustment amount of the slice user group. In addition, for the case that the first target slice user group includes a second master user, the second master user is in the first target slice user group, and a second paired user paired with the second master user is in the second target slice user group, not only the first resource allocation information of the first target user group may be determined to be increased, but also the second resource allocation information of the second target slice user group may be decreased, that is, once a paired user paired with a master user of other slice users is included in the slice user group, it is necessary to determine a resource allocation information decrease amount of the slice user group.

As an example, the first resource allocation information reduction amount of the first target slice user group is positively correlated with the total number of the first PRB resources of the first target slice user group (determined according to the first resource allocation information of the first target slice user group, and is positively correlated with the first resource allocation information of the first target slice user group, for example, the first resource allocation information of the first target slice user group may be multiplied by the total number of PRB resources under the total bandwidth), the preset time window, and the packet size of the first master user, and the first resource allocation information reduction amount of the first target slice user group is positively correlated with the packet size of the first paired user. The first resource allocation information boost quantity of the first target user group is positively correlated with the total number of the first PRB resources of the first target slice user group and a preset time window, and the first resource allocation information boost quantity of the first target user group is positively correlated with the size of a data packet of the second master user. The third resource allocation information reduction amount of the first target slice user group is inversely related to the total number of the first PRB resources of the first target slice user group and the preset time window, and the third resource allocation information reduction amount of the first target slice user group is positively related to the size of the data packet of the third paired user. The fourth resource allocation information reduction amount of the first target slice user group is inversely related to the total number of the first PRB resources of the first target slice user group and the preset time window, and the fourth resource allocation information reduction amount of the first target slice user group is positively related to the size of the data packet of the fourth master user. The reduction amount of the second resource allocation information of the second target slice user group is positively correlated with the total number of the second PRB resources of the second target slice user group (determined according to the first resource allocation information of the second target slice user group, and positively correlated with the first resource allocation information of the second target slice user group, for example, the first resource allocation information of the second target slice user group may be multiplied by the total number of PRB resources under the total bandwidth) and a preset time window, and the reduction amount of the second resource allocation information of the second target slice user group is positively correlated with the packet size of the second paired user.

In this embodiment, the resource allocation information of each slice user group may be dynamically adjusted according to a pairing manner (e.g., intra-group pairing, inter-group pairing, intra-group and inter-group pairing), a size of a paired user data packet, and the like, so as to achieve accurate guarantee for each slice user group and a slice resource reservation effect.

The process of the above resource allocation method is described in detail in an embodiment.

The network slice is an end-to-end logic 'special network' provided based on unified infrastructure and unified network, network resources are flexibly distributed and network capabilities are flexibly combined, a plurality of logic sub-networks with different characteristics are virtualized based on a 5G network, and network service customized according to requirements and oriented to different scenes is provided.

The network slice has 2 characteristics, resource isolation and service guarantee. In the aspect of resource isolation, a core network can realize control plane and data plane network element isolation according to different slices, a transmission network can realize data transmission isolation of different time slots through FLEX-E (flexible Ethernet technology) hard isolation, and a wireless network can realize cell-level resource isolation (including data plane and control plane) based on TA (timing advance) and slice bound admission control and UAC (unified access control) schemes. In the aspect of service guarantee, a wireless network can realize wireless soft slicing and hard slicing, wherein the wireless soft slicing refers to realizing fine scheduling through QoS (quality of service) and slicing + QoS, and the wireless hard slicing refers to realizing resource dimension guarantee through PRB (physical resource block) resource reservation.

The PRB resource reservation can divide a group of slice services which are mainly guaranteed into a slice user group, and the deterministic rate guarantee is provided through the PRB resource reservation. In the reserved bandwidth, users in the slice group share the bandwidth, and when other slice users are congested, the users in the slice are not influenced. Resource reservation may be further subdivided into: 1) The special resources are as follows: only users in the slicing user group are available and cannot be preempted by other slicing user groups; 2) Priority resources: scheduling of a slice user group is guaranteed preferentially, and when resources are left, common users can use the slice user group; 3) Resource sharing: all users compete fairly based on QoS.

Currently wireless slices support frequency domain based slice resource reservation. However, the frequency domain resource reservation has a certain limitation in application scenarios, for example, for the frequency domain resource reservation, in order to avoid uncertainty of guarantee effect caused by mutual resource preemption among different slice user groups, the sum of the proportions of dedicated/priority resources of all slice user groups cannot exceed 100%, that is, "over-sale" cannot be realized, and the number of slice user groups and the reservation proportion that can be guaranteed are limited. And at present, frequency domain resource reservation and space division multiplexing are not combined, namely SU-MIMO can be adopted only when the frequency domain resource reservation is used, the resource reservation effect is poor, and the cell capacity and the guarantee effect are both limited easily.

In order to solve the above problems, embodiments of the present application provide a dynamic slice resource reservation scheme in an air separation scenario, where a pairing strategy is optimized during air separation pairing, different pairing strategies are applied to different scenarios paired within a group, between groups, and within and outside the group, and a reservation ratio of a slice user group is dynamically adjusted according to a pairing condition, so as to improve a cell capacity and achieve an effect of "oversale". The method combines slice resource reservation and MU-MIMO, optimizes an MU-MIMO user pairing algorithm in an air separation scene, dynamically adjusts the reservation proportion according to the statistical pairing condition, and improves the capacity of a cell and the proportion of the reserved resource which can be ensured. The resource allocation method of the embodiment of the application comprises the following processes:

firstly, if the slice determines that the slice frequency domain resource reservation is needed during the subscription, the NSSMF sets a resource allocation proportion, including a dedicated/priority/shared resource proportion, wherein the sum of the dedicated + priority resource proportions of all slice user groups may exceed 100%, and the upper limit of the resource allocation proportion that can be reached is M. The value of M is calculated by NSSMF, and a calculation method of the value of M is as follows.

Wherein, C _MU Cell capacity, C, when MU-MIMO can be adopted for all users _SU For SU-MIMO cell capacity, C _MU And C _SU Are calculated in the case of a typical distribution of users, i.e. can be obtained empirically in advance. Alpha is a discount factor which is a constant of 0-1, and since only part of users may be paired in a certain time slot, the discount factor needs to be multiplied to adapt to normal network conditions, and the discount factor can be given according to the current network experience.

Then, when the base station is scheduled, MU-MIMO pairing, namely user pairing, is required to be carried out, after slice resource reservation is introduced, an MU-MIMO user pairing algorithm is required to be optimized, the cell capacity is ensured to be improved to the maximum extent, and meanwhile, the influence of interference among users on the service rate of a slice user group is avoided as much as possible. The MU-MIMO user pairing optimization algorithm is described as follows:

and for the selection of a main user: and preferentially selecting the users of the slice user group as the primary users of the MU-MIMO, and if the users belong to the slice user group, considering other factors as primary user selection conditions, including spectral efficiency, 5QI (5G QoS identifier) and the like. Because the scheduling priority of the users in the slice user group is higher, the master users are guaranteed to be scheduled preferentially, and the cell capacity is improved.

For paired user selection: the MU-MIMO pairing may cause inter-stream interference, and if the users in the slice user group are paired with the users in the non-slice user group, the MCS (Modulation and coding scheme) needs to be reduced to ensure correct decoding of the terminal due to the interference, which affects the rate certainty guarantee of the slice user group. Therefore, if the master user is a user in the slice user group, when the paired user is selected, the user pairing in the group (the paired user and the master user belong to the same slice user group) is preferentially selected, the user pairing between the secondary groups (the paired user and the master user belong to different slice user groups respectively), and finally the user pairing inside and outside the group (the master user belongs to the slice user group, the paired user does not belong to the slice user group, and the paired user is a non-slice user) is selected, so that the influence on the capacity of the slice user group is reduced.

In addition, when the paired users are selected, a proper pairing scheme can be selected according to whether the paired users belong to the slice user group, so that the interference received by the slice user group users is reduced as much as possible, and the cell capacity is improved to the greatest extent.

Wherein, for intra-group pairing: and selecting the paired users according to the channel capacity increasing degree, namely pre-storing the cell capacity after the users are paired, and preferentially selecting the user with the largest cell capacity increasing degree to perform pairing.

For pairings between groups or pairings within and outside groups: orthogonality of paired users is mainly considered, namely, the orthogonality is calculated by utilizing channel information of a master user and a user to be paired, users with high orthogonality are preferentially selected for pairing, interference among the users is reduced as much as possible, and uncertainty introduced to performance guarantee of a slice user group is avoided.

Secondly, after the MU-MIMO user pairing is completed, the base station dynamically adjusts the resource allocation proportion of each slice user group according to the pairing mode (including intra-group pairing, inter-group pairing, intra-group and inter-group pairing) and the size of a pairing user data packet, so as to realize accurate guarantee of the resources of each slice user group and realize the effect of 'oversale'. The resource allocation proportion adjustment method of one embodiment is as follows:

and respectively calculating the total size of the master user and the paired user data packets of 3 pairing modes of intra-group pairing, inter-group pairing and intra-group pairing of each slice user group in a statistical time window, namely a preset time window, and dynamically adjusting the resource allocation proportion of each slice user group according to the total size. Specifically, the 3 pairing methods adopt different proportion adjustment methods.

Firstly, for intra-group pairing, if the same slice user group is paired, the capacity of the slice user group is improved, the resource allocation proportion (dedicated + priority resource) can be properly compressed, and more PRB resources are reserved for other slice user groups. For example, the total scheduling packet size D of the master user of a slice user group is obtained by statistics in a preset time window T (which can be configured according to the processing capability of the base station and is 1 scheduling time slot at minimum) ₁ The total dispatch packet size of paired users within the slice user group paired with the master user is D ₂ If the latest resource allocation ratio (corresponding to the first resource allocation information) before the current ratio adjustment is X, the total number of allocated PRB resources, that is, the total number of first PRB resources corresponding to the first resource allocation information of the slice user group, can be determined according to X, where the larger the first resource allocation information is, the larger the total number of PRB resources is, for example, N ₁ Assuming that inter-stream interference causes a rate reduction ratio of ρ, the value falls within the range of 0-1, the amount of reduction γ in the first resource allocation ratio for the slice user group can be determined ₁ ：

Wherein the content of the first and second substances,

for the capacity increased by MU-MIMO for the slice user group, the efficiency is the spectrum efficiency (i.e. the preset frequency efficiency) corresponding to the typical MCS, B _PRB The bandwidth occupied by one PRB (e.g., sub-6G (5G band, band below 6G with working frequency of 450MHz-6000 MHz) is generally 360 kHz),

the number of PRBs that need to be compressed.

For inter-group pairing, if the master user and the paired users paired with the master user belong to 2 different slice user groups, the resource allocation proportion (dedicated + priority resource) of the slice user group in which the master user is located can be appropriately increased to reduce the influence on the rate caused by inter-stream interference, and meanwhile, the resource allocation proportion of the slice user group in which the paired users are located is appropriately compressed to save resources. If the slice user group comprises paired users and the paired main users are expected to belong to other slice user groups, the resource allocation proportion of the slice user group can be properly compressed. For example, 2 slice user groups are configured in a cell, and are obtained through statistics in a preset time window T, and the total scheduling packet size of a master user in the slice user group 1 is D ₃ The total scheduling packet size of the paired users in the slice user group 2 is D ₄ The total number of the reserved PRB resources of the previous 2 slice user groups of the proportion adjustment is N ₁ (i.e., the total number of first PRB resources corresponding to the first resource allocation information of the slice user group 1) and N ₂ (i.e., the total number of the second PRB resources corresponding to the first resource allocation information of the slice user group 2) is determined according to the first resource allocation proportion of the 2 slice user groups, and assuming that the rate reduction proportion caused by inter-stream interference is ρ, the first resource allocation proportion boost amount γ of the slice user group 1 may be determined ₂ ：

And determining a second resource allocation ration reduction γ for the slice user group 2 ₃ ：

Similarly, the adjustment ratios of the 2 slice user groups can be further calculated according to the statistical data of the master user in the slice user group 2 and the paired users in the slice user group 1. By adopting the calculation method, the proportion adjustment of all the 2 slice user groups subjected to inter-group pairing can be traversed in sequence. For example, the total scheduling packet size of paired users in slice user group 1 is D ₅ The third resource allocation proportion reduction amount gamma of the slice user group 1 can be determined ₄ ：

For intra-group and intra-group pairing, a master user belongs to a slice user group, a paired user does not belong to the slice user group, if the users of the slice user group are paired with non-slice users, the rate of the slice user group is influenced, and the resource allocation proportion (special + priority resource) of the slice user group in which the master user is located needs to be properly improved. For example, the total scheduling packet size of the primary users paired in and out of a group of a slice user group is counted and obtained within a preset time window T and is D ₆ Assuming that inter-stream interference causes a rate reduction ratio of ρ, the fourth resource allocation ratio for the slice user group is reduced by an amount γ ₅ ：

In addition, in order to verify the dynamic slice resource reservation effect in the MU-MIMO scene, the actual performance and the resource use condition of the slice user group can be monitored, and the resource allocation scheme is evaluated based on the monitoring result. The base station can count the PRB resource occupation condition and the average rate of the slice user group in a period of time, and report the statistical result to the NSSMF through an interface. The NSSMF may evaluate the effect of adjusting the MU-MIMO and resource allocation ratio of the base station according to the statistical result. For example, if the proportion of the PRB resources actually occupied by the slice user group is lower than the allocation proportion (for example, 30% is reduced to 20%), and the average rate just meets the requirements of the slice user group SLA (Service-Level Agreement), it indicates that the implementation effect of the resource allocation scheme is better.

That is, in the resource allocation method implemented in the present application, for a scenario in which resource reservation of a slice user group is configured, an MU-MIMO pairing optimization algorithm is proposed, which includes a master user selection method and a paired user selection method for a sub-scenario, so that cell capacity is improved to the maximum extent while the rate of the slice user group is ensured as much as possible. The method for dynamically adjusting the reservation proportion of each slice user group by the base station according to the pairing mode (including intra-group pairing, inter-group pairing and intra-group and inter-group pairing) and the size of a paired user data packet is provided, so that the accurate guarantee of all slice user groups and the 'over-sale' of slice reservation resources are realized. The effect of the dynamic slice resource reservation scheme in the MU-MIMO scene can be evaluated by counting the actual performance and resource use condition of the slice user group.
