Detailed ways

The specific embodiments of the present invention will be further described below with reference to the accompanying drawings. The following examples are only used to illustrate the technical solutions of the present invention more clearly, and cannot be used to limit the protection scope of the present invention.

In the embodiment of the present invention, it is assumed that there are U adjacent cells with co-channel interference, there are M randomly distributed users in each cell, the number of radio resource blocks of each cell base station is N, and the system bandwidth is B.

Specifically, in the scheduling period, each resource block of each cell is allocated to one user, and users in different cells have co-channel interference.

The Signal to Interference plus Noise Ratio (SINR) of resource block n allocated to user m in cell u is as follows:

为用户m在其他小区同频干扰信道上的增益，p_u,m,n为小区u用户m被分配资源块n的下行发射功率，z为高斯白噪声。Among them, G _u,m,n is the channel gain of cell u user m to resource block n,

is the gain of user m on the co-channel interference channel of other cells, p _u,m,n is the downlink transmit power of resource block n allocated to user m in cell u, and z is white Gaussian noise.

Further, according to Shannon's formula, under the condition of a certain bit error rate, the specific calculation formula of the maximum throughput of resource block n allocated to user m in cell u is as follows:

为常数，B表示系统带宽，N表示每个小区资源块的数量，BER表示误码率。where B ₀ =B/N,

is a constant, B represents the system bandwidth, N represents the number of resource blocks in each cell, and BER represents the bit error rate.

Further, the specific calculation formula of the total downlink throughput is as follows:

Among them, λ _u,m,n =1 indicates that the base station u allocates the resource block n to the user m, on the contrary, λ _u,m,n =0 indicates that the base station u does not allocate the resource block n to the user m.

Further, considering the requirements for fairness and throughput of the multi-cell system in the grid slicing service scenario, the embodiment of the present invention proposes that the grid resource dynamic scheduling target is max C(λ _u,m,n ,p _u,m,n ).

Specifically, the constraints are as follows:

C2:λu _,m, n∈{0,1}

Among them, C1 and C2 are constraints on resource blocks, C1 means that each resource block of each cell is allocated to 1 user in the scheduling period; C3 is the power constraint on each base station, P _u means the transmit power of base station u upper limit; C4 is the resource transmission rate constraint for cell u user m.

In order to achieve the above goal of dynamic grid resource scheduling, the method for dynamic grid resource scheduling provided by the embodiments of the present invention can be applied to the system architecture shown in FIG. 1 , where the system architecture includes a base station 100 and a user 200 .

In this embodiment of the present invention, the base station 100 is configured to acquire resource scheduling requests of multiple users 200 at the current moment.

It should be noted that the resource scheduling request includes the amount of data to be sent, the resource transmission rate, and the data packet queuing delay of each user.

In the embodiment of the present invention, the user is a network slice user.

Further, the slice types of network slices include multiple types, such as video type, voice type, and so on.

For example, there are 10 adjacent cells with co-channel interference, there are 20 randomly distributed users in each cell, and 10 cells correspond to 10 base stations respectively. The cell corresponding to base station 1 includes two slice types, namely slice type A and slice type B, respectively. Slice type A contains 6 users, and slice type B contains 4 users.

The base station 100 is configured to determine the resource scheduling priority of each user according to the amount of data to be sent, the resource transmission rate, and the data packet queuing delay, and schedule multiple resource blocks to be allocated according to the resource scheduling priority.

It should be noted that FIG. 1 is only an example of the system architecture of the embodiment of the present invention, which is not specifically limited by the present invention.

Based on the system architecture shown above, FIG. 2 is a schematic flowchart corresponding to a method for dynamic scheduling of power grid resources provided by an embodiment of the present invention. As shown in FIG. 2 , the method includes:

Step 201: Obtain resource scheduling requests of multiple users at the current moment and multiple resource blocks to be allocated from different base stations.

It should be noted that the resource scheduling request includes the amount of data to be sent, the resource transmission rate, and the data packet queuing delay of each user.

Further, in this embodiment of the present invention, the user is a network slice user.

It should be noted that the fifth-generation mobile communication provides users with customized services in the form of network slices. Different users require different service qualities. According to the different service qualities, the embodiment of the present invention performs the following steps on the radio access network side. Scheduling of resources to be allocated to meet the service requirements of different users end-to-end.

Step 202: Determine the resource scheduling priority of each user according to the amount of data to be sent, the resource transmission rate, and the data packet queuing delay.

Specifically, the formula for calculating the resource scheduling priority of user m at time t is as follows:

表示小区u用户m在时刻t的待发送数据量，

表示所有用户在时刻t的待发送数据量。

表示用户m在时刻t的资源传输速率，

表示用户m在时刻t前的预设时间段内的平均资源传输速率，

表示用户m在时刻t的数据包在缓冲区的排队时延，

表示用户m对应的最大排队时延，

表示用户m的丢包率界限，

取对数后为负数。in,

represents the amount of data to be sent by user m in cell u at time t,

Indicates the amount of data to be sent by all users at time t.

represents the resource transmission rate of user m at time t,

is the average resource transmission rate of user m in the preset time period before time t,

represents the queuing delay of the data packets of user m in the buffer at time t,

represents the maximum queuing delay corresponding to user m,

represents the packet loss rate limit of user m,

Negative after taking the logarithm.

It should be noted that the maximum queuing delay and packet loss rate limits corresponding to user m are determined by the service type of the network slice corresponding to the user.

In order to reduce the algorithm complexity, the embodiment of the present invention decomposes the above optimal problem into the following two steps:

Step 1: Allocating resources under the condition of equal power to each cell.

Step 2: Based on the resource allocation result of each cell, perform power allocation among cells.

Specifically, the resource transmission rate is determined by the channel bandwidth corresponding to the user, the noise power, and the transmit power of the base station; the transmit power of the base station corresponding to each user among the multiple users is equal.

In the embodiment of the present invention: r=wlog2(1+s/n), s represents the transmit power of the base station. In the embodiment of the present invention, the transmit power s of the base station corresponding to each user is made equal, that is, each cell is subjected to equal power transmission. Resource allocation.

Step 203: Schedule multiple resource blocks to be allocated according to resource scheduling priorities.

For example, user A1 has the highest resource scheduling priority among the users covered by base station A, the first resource block of base station A is allocated to user A1, and user B1 has the highest resource scheduling priority among the users covered by base station B, The first resource block of base station B is allocated to user B1.

The above scheme, by adjusting the resource scheduling priority of users, dynamically updating the priority of each service terminal to reasonably schedule channel resources, meeting the differentiated requirements of various services of different slice users, and taking into account the transmission rate, delay and scheduling fairness of slice users. It realizes the efficient use of network resources and maximizes the throughput of the system.

Further, after the resource allocation under the equal power of each cell is completed, since λ _u,m,n has been determined, _cu,m,n , γ _u,m,n and p _u,m,n can be simplified as c _u,n , γ _u,n and p _u,n .

In the embodiment of the present invention, the specific calculation formula of the total downlink throughput is as follows:

Further, based on the above formula, it can be obtained:

最大，那么电网系统的下行链路吞吐量最大。It can be seen from the above formula that only the

maximum, then the downlink throughput of the grid system is maximum.

Simplified after resource block allocation.

Based on the above principles, in step 203 in this embodiment of the present invention, the step flow is as shown in FIG. 3 , and the details are as follows:

Step 301: Determine a first set of users according to resource scheduling priorities.

It should be noted that each user in the first user set corresponds to a different base station; the resource scheduling priority of each user in the first user set is the highest among multiple users covered by the corresponding base station.

For example, base station A covers user 1, user 2, and user 3, where the resource scheduling priority corresponding to user 2 is the highest, and base station A allocates resource blocks to user 2; base station B covers user 4, user 5, and user 6, where The resource scheduling priority corresponding to user 6 is the highest, and base station B allocates resource blocks to user 6. Both user 2 and user 6 are in the first user set.

Step 302: Determine the signal-to-interference-noise ratio corresponding to each base station according to the first user set.

In a possible implementation manner, the standard deviation {σ ₁ ,σ ₂ ,...,σ _N } of the signal-to-interference-noise ratio of the same-frequency resource blocks is calculated.

in,

Step 303: Determine the transmit power of each base station according to the signal-to-interference-noise ratio corresponding to each base station.

Specifically, the first base station and the upper limit of the transmit power are determined according to the signal-to-interference-noise ratio corresponding to each base station.

It should be noted that the signal-to-interference-to-noise ratio corresponding to the first base station is the lowest.

According to σ ₁ :σ ₂ :...:σ _N , calculate the upper limit of the power of the same-frequency resource block. The specific calculation formula is as follows:

In the embodiment of the present invention, the ratio of the standard deviation of the signal-to-interference and noise ratio of the same-frequency channel is used to obtain the upper limit of power in the same-frequency resource block.

Further, the upper limit of the transmit power is taken as the transmit power of the first base station.

The transmit power of the second base station is determined according to the principle of equal signal-to-interference-noise ratio.

It should be noted that the second base station is a base station other than the first base station among the multiple base stations corresponding to the first user set.

In the embodiment of the present invention, the resource blocks of other base stations perform power allocation according to γ _1,n =...=γ _U,n . The power of each cell should guarantee the following inequality:

The above scheme allocates the maximum power to the channel resource with the worst signal-to-interference-noise ratio, balances the signal-to-interference and noise ratio of users in the same-frequency slice, reduces the co-channel interference between cells, and further improves the throughput in the grid multi-cell system.

Step 304: Allocate the plurality of resource blocks to be allocated to the users in the first user set according to the transmit power of each base station.

In the embodiment of the present invention, the coordination is performed according to the downlink transmit power of the sub-channel to satisfy γ _1,n =...=γ _I,n . At the same time, considering the fairness of edge users, the channel resource with the worst signal-to-interference-noise ratio is allocated the maximum power.

The above scheme, by aiming at the problem of co-channel interference in multi-cell resource scheduling in power scenarios, reasonably allocates transmit power to users who obtain channel resources, improves system throughput while reducing co-channel interference between cells, and reduces co-channel interference. Throughput loss caused by frequency interference, improve the fairness of resource allocation for different users in multi-cell power service scenarios, and better meet the service quality requirements of different power service terminals.

Further, in this embodiment of the present invention, after step 203, multiple resource blocks to be allocated are deleted from the current resource block list;

Determine whether the resource block list is empty;

If it is empty, end the scheduling, otherwise continue to allocate until the resource block list is empty.

In the above solution, the efficiency of scheduling channel resources is improved through the resource block list.
