Description

Bandwidth allocation method and device
Technical Field

Background
In the context of the 4th generation mobile communication technology (4G), a bandwidth of a User Equipment (UE) is consistent with a whole bandwidth of a base station, and after the UE accesses the base station, the bandwidth of the UE cannot be changed.
However, with the advent of the fifth generation mobile communication technology (5th generation wireless systems, 5G), the bandwidth allocation of UEs has varied. The whole bandwidth of the base station is divided into several isolated partial Bandwidths (BWPs), for example, the bandwidth of 100MHz is divided into 3 BWPs: 20MHz, 35MHz and 45 MHz. In 5G, one BWP may configure multiple users, or allocate multiple BWPs to one user, but one user can only activate one BWP at the same time. Obviously, in the 5G background, how to dynamically allocate an appropriate BWP to a user makes the overall communication efficiency and communication resource utilization higher, which is significant. However, there is no allocation method for BWP of users, which is a problem to be solved.

Detailed Description
In order to better understand the technical solutions, the technical solutions will be described in detail below with reference to the drawings and the specific embodiments of the specification, and it should be understood that the specific features in the embodiments and examples of the present application are detailed descriptions of the technical solutions of the present application, but not limitations of the technical solutions of the present application, and the technical features in the embodiments and examples of the present application may be combined with each other without conflict.
Under the 4G background, the bandwidth of User Equipment (UE) is consistent with the entire bandwidth of the base station, and after the UE accesses the base station, the bandwidth of the UE cannot be changed. The multi-user frequency selective resource scheduling is to schedule each user to a better frequency band in the bandwidth of the UE for transmission, thereby improving the overall frequency spectrum efficiency of the system under the multi-user and increasing the system capacity. With 5G, the bandwidth of the UE can be divided into multiple BWPs, so the bandwidth allocation of the UE varies differently, but at present, there is no allocation method for the BWPs of the user, which does not conform to the idea of efficient communication in the 5G context. To this end, the present application provides a bandwidth allocation method.
Step 101: within a first preset duration, when determining that the communication resource distribution of the bandwidth BWPs of each part of the whole bandwidth is unbalanced, the base station determines a first target BWP of which the communication resource meets a first preset rule from the BWPs; and/or within a second preset duration, when the base station determines that the communication efficiency of each BWP is inefficient, determining, from the BWPs, a second target BWP whose communication efficiency meets a second preset rule.
Step 102: and the base station determines a user to be adjusted from the users of the first target BWP and/or the second target BWP, and determines a BWP distributed to the user to be adjusted from candidate BWPs.
Wherein, the candidate BWP is a BWP except the first target BWP and/or the second target BWP in each BWP.
It should be noted that, when determining whether the communication resource allocation of each bandwidth BWP of the entire bandwidth is balanced, the base station may determine whether the frequency domain resource allocation in the communication resource is balanced according to a certain criterion determined by the communication resource indicator and the corresponding communication resource indicator, such as the communication resource indicator being the number of idle RBs of each bandwidth BWP, and then select BWP according to whether the average power consumption of each bandwidth BWP is balanced, so as to reasonably allocate BWP and improve the power efficient utilization.
In addition, there are various judgment criteria for equalization, such as the statistics (e.g., standard deviation, variance, etc.) of the communication resource indicators of each BWP compared with a threshold. As another example, RB usage for each BWP may be clustered by a clustering method, such as clustering the RB usage for each BWP, as measured by the distribution of outliers (e.g., cluster centers are mean, deviate by more than a standard deviation or some threshold), or clustering the power consumption for each BWP, as measured by the distribution of outliers (e.g., cluster centers are mean, deviate by more than a standard deviation or some threshold). Further, the RB usage rate and power consumption level of each BWP may also be selected simultaneously as two dimensions of the cluster, measured according to the distribution of outliers (cluster center is mean, calculated euclidean distance deviation exceeds a threshold).
Furthermore, the base station may determine whether the communication efficiency of each BWP is inefficient in various ways, such as different communication efficiency indicators and judgment criteria for whether the communication efficiency is inefficient. For example, the spectrum efficiency, the packet error rate, the retransmission times, and the like of each BWP may be set as a threshold to design a rule whether the communication efficiency of each BWP is low.
It should be noted that the user to be adjusted may be at least one user with the lowest spectral efficiency among the users of the first target BWP or the second target BWP. The spectral efficiency reflects the amount of data transmitted per unit frequency, reflecting the utilization of BWP.
In a possible implementation manner, the first preset time duration is a downlink time slot for communication between the base station and a user; the second preset time is an uplink time slot of the communication between the base station and the user. In this way, the work flow is inserted into the nodes of which the downlink scheduling is finished and the uplink receiving is finished respectively, the influence on the normal work flow of the protocol is minimized, and the method can be conveniently connected with the existing communication protocol.
In steps 101 to 102, the specific manner of determining the BWP allocated to the user to be adjusted from the candidate BWPs may be:
the base station sets the distribution probability of each BWP in the candidate BWPs distributed to the user to be adjusted according to the communication quality of the candidate BWPs; and the base station determines the BWP allocated to the user to be adjusted according to the allocation probability of each BWP in the candidate BWPs allocated to the user to be adjusted.
It should be noted that the evaluation Indicator of the communication Quality of the BWP candidate may be a Channel Quality Indicator (CQI) of the user in the BWP candidate, or a reference signal received power (L1-RSRP) of the user in the BWP candidate, or a signal to interference noise ratio (SINR) of the user in the BWP candidate.
The rule for setting the allocation probability of each BWP in the candidate BWPs to the user to be adjusted may be: the allocation probability of each BWP to the user to be adjusted is positively correlated with the communication quality of the BWP.
Specifically, the first allocation probability is greater than the second allocation probability; the first distribution probability is a corresponding distribution probability when the communication quality of the candidate BWP is higher than the communication quality of the first target BWP and/or the second target BWP; the second probability is a corresponding distribution probability when the communication quality of the candidate BWP is lower than the communication quality of the first target BWP and/or the second target BWP.
Specifically, how to set the quantity relationship between the distribution probability and the indicator of the communication quality is not limited herein, as long as the first distribution probability is greater than the second distribution probability.
In steps 101 to 102, the specific way of determining whether the communication resource allocation of the bandwidth BWP of each portion of the entire bandwidth is balanced may be:
and the base station determines whether the communication resource allocation of each BWP is balanced or not according to the number of idle resource blocks of each BWP and the number of occupied user resource blocks of the whole bandwidth.
And the number of occupied user resource blocks is obtained according to the total number of the resource blocks of the whole bandwidth and the number of users of the base station. The number of occupied resource blocks of the user may be an average value of the number of occupied resource blocks of the user of the base station.
In steps 101 to 102, the step of determining whether the communication efficiency of each BWP is inefficient may specifically be:
and the base station determines whether the communication efficiency of each BWP is low or not according to the average throughput and the maximum transmission data volume of each user in each BWP.
More specifically, the manner of determining whether the communication efficiency of each BWP is inefficient may be:
the base station determines the frequency efficiency of each BWP according to the average throughput and the maximum transmission data volume of each user in each BWP; the base station determines whether the communication efficiency of each BWP is inefficient according to the frequency efficiency of each BWP.
Wherein, the frequency efficiency of each BWP may refer to a ratio of a bandwidth occupied in each BWP to the whole BWP.
The method from step 101 to step 102 will be described in detail below with reference to two specific flow charts.
The execution flow of the bandwidth allocation method from step 101 to step 102 includes two flows: a first process and a second process. The first process designs a policy with the number of idle RBs of BWP as an angle, and the second process designs a policy with the BWP spectrum efficiency as an angle, as shown in fig. 2, which is specifically described as follows:
procedure one
It should be noted that the values of the parameters in the first process only depend on the steps in the first process, the first process and the second process are independent from each other, and the first process is not affected by the steps in the second process.
Step 1-1, when each user initially accesses, a base station configures default initial BWP for the user;
step 1-2, after the resource scheduling of each Transmission Time Interval (TTI) is completed, updating the resource utilization of each BWP in the scheduling, that is, the number of Resource Blocks (RBs) used in the scheduling.
Step 1-3, counting BWP resource utilization of a first preset duration to obtain average idle RB number of each BWP, which is expressed as
Figure BDA0002445683100000091
It should be noted that the setting of the different first preset duration affects the time granularity of BWP switching.
Step 1-4, if the current flow II is not in the execution process, calculating the maximum deviation value of the average idle RB number, which is expressed as
ΔRBunused＝max(RBunused)-min(RBunused)。
Step 1-5, if the maximum number of scheduling users per TTI is N, the RB number (the number of occupied user resource blocks) of each user which is averagely allocated to the whole bandwidth of the base station can be set
Figure BDA0002445683100000092
) Is a deviation threshold for the number of free RBs, if
Figure BDA0002445683100000093
Triggering a BWP reselection process, otherwise keeping the current BWP configuration by all users;
steps 1-6 may only process one user on one BWP per BWP reselection, the selected BWP being min (RB)unused) And selecting the user with the lowest spectral efficiency from the users working on the BWP corresponding to the BWP, wherein the user spectral efficiency evaluation value is calculated according to the following formula:
v＝SE(MCS)*(1-BLER)
wherein, se (MCS) represents the spectrum efficiency corresponding to the average of the Modulation and Coding Scheme (MCS) of the user in the BWP for a period of time, and BLER is the packet loss rate of the user in the period of time.
Step 1-7, the user selectable BWPs are divided into two categories, the CQI of the candidate BWP of the first category is better than the CQI of the current working BWP or the CQI of the candidate BWP is unknown, the CQI of the candidate BWP of the first category is lower than the CQI of the current working BWP, and the probability of the candidate BWP being selected is as follows:
Figure BDA0002445683100000094
wherein, PBWPiAnd (3) the probability of the ith BWP being selected is probability weighting, the value can be flexibly set according to a specific scene, k represents the number of the first BWPs, and t represents the number of the second BWPs.
1-8, selecting BWP by adopting a roulette algorithm based on the probability calculated in the step 1-7;
and 1-9, executing BWP switching according to the protocol specification, and ending the first flow.
Flow two
It should be noted that the values of the parameters in the second process only depend on the steps in the second process, the first process and the second process are independent of each other, and the second process is not affected by the first process.
Step 2-1, when the user initially accesses, the base station configures default initial BWP for the user;
step 2-2, when the uplink scheduling receives a Cyclic Redundancy Check (CRC) Check, or the downlink scheduling receives an Acknowledgement Character (ACK), the transmission is considered to be successfully completed, otherwise, the transmission fails; the frequency efficiency of each BWP can be updated by the following formula
Figure BDA0002445683100000101
Wherein Thr isiRepresents the average throughput, TBS, of the ith useri,maxRepresents the maximum amount of data that can be transmitted by the ith user on the RB to which the ith user is scheduled, and S is the total number of users;
step 2-3, if the current process is not in the execution process and the minimum frequency efficiency (V value) of each BWP is lower than the preset threshold of frequency efficiency, triggering the BWP reselection process, otherwise, all users keep the current BWP configuration;
step 2-4, only one user on one BWP can be processed in every BWP reselection, where the selected BWP is the BWP corresponding to the minimum V value, and the user with the lowest spectral efficiency is selected from the users working on the BWP, and the spectral efficiency evaluation value is calculated according to the following formula:
v＝SE(MCS)*(1-BLER)
wherein se (MCS) indicates the spectrum efficiency corresponding to the MCS mean value of the user in the BWP for a period of time, BLER is the packet loss rate of the user in the period of time, and it should be noted that v here has no relationship with v in the first process, and the value depends on steps 2 to 4;
step 2-5, the user selectable BWPs are divided into two categories, the CQI of the candidate BWP of the first category is better than the CQI of the current working BWP or the CQI of the candidate BWP is unknown, the CQI of the candidate BWP of the first category is lower than the CQI of the current working BWP, and the probability that the candidate BWP is selected is as follows:
Figure BDA0002445683100000111
wherein, PBWPiThe probability of being selected for the ith BWP is probability weighting, the value can be flexibly set according to a specific scene, and k represents the above-mentioned the ith BWPThe number of BWPs of one class, t, represents the number of BWPs of the second class, it should be noted that, here, k, t have no relation with k, t in the first flow, and the value depends on step 2-5.
Step 2-6, based on the probability calculated in step 2-5, adopting a roulette algorithm to select BWP;
and 2-7, executing BWP switching according to the protocol specification, and ending the second flow.
It should be noted that, when the first and second procedures are applied in the 5G NR scenario, the frame structure (TDD mode) defined by the 5G protocol specifies an explicit timing sequence for the base station to transmit and receive. During online processing, the first process is accompanied by a downlink time slot, the second process is accompanied by an uplink time slot, and the two processes are executed alternately to form an iterative convergence dynamic programming model. The dynamic planning model can be used for finding out the deviation in time and correcting in time in the working process of the base station.
In summary, in the 5G NR system, a new problem is generated in the frequency selective scheduling technology, and the present application provides a solution for selecting a bandwidth, which can improve the utilization efficiency of limited spectrum resources and provide a better service experience for a user. In addition, in the transceiving process specified by the protocol, nodes which are finished by downlink scheduling and uplink receiving are selected to be inserted into the working process, and the influence on the normal working process of the protocol is minimized, so that the method can be conveniently connected with the existing communication protocol, has good practicability, and can improve the spectrum efficiency of the system and improve the system capacity.
