Description

Resource allocation method, device and computer readable storage medium

Technical Field

The present application relates to the field of communication technology, and in particular to a resource allocation method, device and computer-readable storage medium.

Background Art

Under the time division duplexing (TDD) standard of the fifth generation (5G) network, there are diversified network application scenarios. In order to adapt to the diversified network application scenarios, different access network devices will be configured with different frame structures. If two adjacent access network devices are configured with different frame structures, the downlink time slot of one access network device (denoted as access network device 1) will interfere with the uplink time slot of another adjacent access network device (denoted as access network device 2). This will cause access network device 1 to interfere with access network device 2 using the uplink time slot to transmit data when using the downlink time slot, thereby affecting the uplink transmission performance of access network device 2.

In the description of the present application, unless otherwise specified, “plurality” means two or more.

The following explains the terms involved in the embodiments of the present application to facilitate the reader's understanding.

(1) Co-construction and sharing

Co-construction and sharing refers to a network construction solution in which different operators share carrier resources. Through co-construction and sharing, one access network device can carry services of multiple operators, or one access network device can carry multiple types of services, thereby reducing the network construction costs of operators.

Co-construction and sharing include: independent carrier sharing, operator-level shared carrier sharing, and service type-level shared carrier sharing.

In the application scenario of independent carrier sharing, the access network device configures an independent carrier for a type of service of an operator. For example, the access network device configures an independent carrier C for a type B service of operator A.

In the application scenario of operator-level shared carrier sharing, the access network device configures a shared carrier for multiple types of services of an operator. For example, the access network device configures shared carrier G for type D, type E, and type F services of operator A.

In the application scenario of service type-level shared carrier sharing, the access network device configures a shared carrier for a type of service of multiple operators. For example, the access network device configures shared carrier Q for type J services of operator A, operator H, and operator I.

It should be pointed out that the frequency band of the antenna radio frequency of the current access network equipment is constantly increasing, and the coverage range of the access network equipment is correspondingly reduced. The number of access network equipment required to be deployed to cover the same area is constantly increasing. In addition, the current access network equipment usually adopts multiple in multiple out (MIMO) technology, and the number of antennas of the access network equipment has increased significantly, which has also led to an increase in the number of access network equipment deployed in the same area. With the increase in the number of access network equipment to be deployed as mentioned above, the cost of operator network construction has also greatly increased. The above-mentioned co-construction and sharing network construction solution can well solve the problem of increased operator network construction costs caused by the increase in access network equipment.

(2) 5G quality of service identifier (5QI)

5QI is used to indicate the service characteristics of different services in 5G networks. For example, the service characteristics of guaranteed bit rate (GBR) services and non-guaranteed bit rate (non-GBR) services. In the fourth generation (4G) network, the service characteristics of different services can be represented by the quality of service class identifier (QCI).

It should be noted that 5QI can be obtained through the session management function-unified data management registration information (SMF-UDMregistration). 5QI can also be obtained from the initial context setup request (i.e. INITIAL CONTEXT SETUP REQUEST) message of the N2 interface or the protocol data unit session resource setup request (i.e. PDUSESSION RESOURCE SETUP REQUEST) message when the terminal device initiates a service request.

It should be pointed out that 5QI can be used to characterize the service characteristics of a service, and can also be used to characterize the service characteristics of a service (which can be multiple services).

As an example, the following Table 1 shows the 5QIs of various types of GBR services.

As shown in Table 1, 5QI may include at least one of the following: 5QI value (5QI Value), default priority (DefaultPriority Level), packet delay budget (Packet Delay Budget), packet error rate (Packet Error Rate), default averaging window (Default Averaging Window), and typical services (Example Services).

Table 1

As another example, the following Table 2 is a 5QI mapping table for various types of non-GBR services.

As shown in Table 2, the categories of information included in the 5QI of the non-GBR service are the same as the categories of information included in the 5QI of the above-mentioned GBR service.

Table 2

It should be noted that the 5QI value in 5QI (i.e., 5QI Value) can be used to distinguish between GBR services and non-GBR services. For example, when the 5QI value is 1, 2, 3, 4, 65, 66, or 67, it can be used to characterize the service as a GBR service. When the 5QI value is 5, 6, 7, 8, 9, 69, or 70, it can be used to characterize the service as a non-GBR service.

(3) TDD system

A TDD system refers to a system in which the transmission and reception share the same radio frequency, and the uplink and downlink use different time slots for communication.

It should be noted that in the current TDD system, in order to effectively improve the uplink and downlink throughput of the network, different frames need to be allocated to different access network devices to transmit data. In this case, because different access network devices are configured with different frames (i.e., the uplink and downlink time-frequency resource configurations are inconsistent), there is serious cross-interference between different access network devices, which has a serious impact on the data transmission between adjacent access network devices.

(4) Cross-interference

Cross interference refers to the interference between signals transmitted in uplink time slots and signals transmitted in downlink time slots of different access network devices.

The interference between the signal transmitted on the uplink time slot and the signal transmitted on the downlink time slot includes: the interference caused by the signal transmitted on the uplink time slot to the signal transmitted on the downlink time slot, and the interference caused by the signal transmitted on the downlink time slot to the signal transmitted on the uplink time slot.

It should be noted that the interference caused by the signal transmitted in the uplink time slot to the signal transmitted in the downlink time slot mainly occurs between the devices on the user side (for example, terminal devices). The interference caused by the signal transmitted in the downlink time slot to the signal transmitted in the uplink time slot mainly occurs between the devices on the wireless network side (for example, access network devices).

Exemplarily, as shown in Figure 1, terminal 1 accesses access network device 1 through a communication link, and terminal 2 accesses base station 2 through a communication link. When access network device 1 currently uses downlink subframe 103 (denoted as DL103 in Figure 1) and access network device 2 currently uses uplink subframe 203 (denoted as UL103 in Figure 1), the downlink signal transmitted between terminal 1 and access network device 1 will interfere with the uplink signal transmitted between terminal 2 and access network device 2. The above interference is cross interference.

It should be noted that there is cross interference between access network devices, that is, access network device 1 causes interference to access network device 2; or, access network device 2 causes interference to access network device 1.

It should be pointed out that in the scenario of cross interference, there will also be interference from adjacent resource blocks, interference from other control channels, and interference from broadcast channels between access network devices.

(5) Time-frequency resources

Time-frequency resources include time domain resources and frequency domain resources.

The time domain resource refers to a time resource, which may include multiple frames. A frame may include multiple time slots, which may include: an uplink time slot, a downlink time slot, and a special time slot.

Frequency domain resources refer to frequency resources, which may include multiple carriers. Carriers may include independent carriers and shared carriers.

It should be noted that the access network equipment uses specific time-frequency resources for data transmission, that is, the access network equipment carries the service data on specific frequency domain resources for transmission within specific time domain resources. For example, the access network equipment carries the data of service B on carrier C for transmission within frame 1. For another example, the access network equipment carries the data of service D on carrier C for transmission within frame 2.

The service data of multiple access network devices can be carried on the same carrier. For example, the service data exchanged between access network device 1 and access network device 2 and the terminal device are all carried on carrier A.

Exemplarily, the time slot resource configuration of the service data of access network device 1 carried on carrier A is: frame structure x, and the time slot resource configuration of the service data of access network device 2 carried on carrier A is: frame structure y. The structures of the uplink time slot and the downlink time slot in frame structure x and frame structure y are shown in Table 3.

Table 3

DL represents a downlink time slot, and UL represents an uplink time slot.

For example, during the transmission process, DL12 in frame structure x may interfere with UL22 in frame structure y; DL13 in frame structure x may interfere with UL23 in frame structure y; and DL17 in frame structure x may interfere with UL27 in frame structure y.

The above is a brief introduction to some concepts involved in the embodiments of this application.

For example, the communication system can be a third generation partnership project (3GPP) communication system, such as a 5G communication system, a NR system, a NR vehicle-to-everything (V2X) system, and other next-generation communication systems, or a non-3GPP communication system without limitation.

At present, methods for processing the degradation of data transmission performance caused by cross interference between adjacent access network devices mainly include the following method 1 and method 2.

Method 1: Physical isolation method, that is, increasing the isolation between two access network devices in physical space.

For example, the isolation between two access network devices in physical space may be increased by reducing the coverage overlap between the two access network devices.

For another example, the physical spatial isolation between the two access network devices may be increased by increasing the distance between the two access network devices.

Problems with Method 1: Increasing the physical isolation between two access network devices has significant scenario limitations in the specific implementation process. For example, Method 1 is not applicable in dense networking scenarios.

Method 2: According to the frame structure of adjacent access network devices, determine the downlink time slots between adjacent access network devices that may interfere with other access network devices; when the interference caused by the above downlink time slots to other access network devices is relatively large, close the above downlink time slots.

Problems with Method 2: Using Method 2 will reduce the utilization rate of the time and frequency resources of the access network equipment, which will greatly reduce the downlink capacity of the access network equipment. In other words, although using Method 2 can alleviate the impact of cross-interference on data transmission to a certain extent, Method 2 will greatly reduce the utilization rate of the time and frequency resources of the access network equipment, and still affect the transmission performance of the access network equipment to a certain extent.

In order to solve the problem of reduced data transmission performance due to cross interference in the above-mentioned prior art, the embodiment of the present application proposes a resource allocation method, which can effectively improve the transmission performance of access network equipment. As shown in Figure 4, the method includes:

S401. A first access network device obtains service information of at least one service in the first access network device.

The service information includes at least one of the following: information about the operator and service type.

The home operator information can be determined based on public land mobile network (PLMN) information. The first access network device can obtain the PLMN information from the system information block (SIB) 1.

The service types in the above service information can be divided into public network type services and private network type services. Among them, public network type services refer to services carried on public networks; private network type services refer to services carried on private networks.

In a possible implementation, the first access network device may determine the service type of each service according to a data network name (DNN) corresponding to each service.

Specifically, the first access network device obtains the DNN corresponding to each service from the protocol data unit session establishment request (ie, PDU session establishment request), and then determines the service type of each service according to the DNN corresponding to each service.

In yet another possible implementation, the first access network device may determine the service type of each service according to an access point name (APN) of each service.

It should be noted that the at least one service of the first access network device may be all or part of the services supported by the first access network device, which is not limited in the present application.

It should be noted that the first access network device may be an access network device that is interfered with or an access network device that generates interference, and this application does not limit this. For example, the first access network device may be access network device 1 in FIG. 1 (i.e., an access network device that generates interference). For another example, the first access network device may be access network device 2 in FIG. 1 (i.e., an access network device that is interfered with).

S402: The first access network device determines at least one first service from at least one service according to the service information.

In a possible implementation manner, the first service is a service having the same service information among at least one service.

When the parameters in the service information are different, the first service determined by the first access network device is also different. The parameters in the service information can be specifically divided into the following scenarios: Scenario 1, the service information only includes the information of the home operator. Scenario 2, the service information only includes the service type. Scenario 3, the service information includes both the information of the home operator and the service type. The following describes Scenario 1, Scenario 2, and Scenario 3 respectively:

Scenario 1: Business information only includes the information of the home operator.

In this scenario, the first access network device determines that the service with the same operator information is the first service.

In one example, the home operators involved in this application include operator A, operator B and operator C.

After the first access network device obtains the operator information of each service in at least one service, the first access network device determines that the service with operator A is a first service; the first access network device determines that the service with operator B is another first service; the first access network device determines that the service with operator C is another first service.

Scenario 2: Business information only includes business type.

In this scenario, the first access network device determines that the service with the same service type is the first service.

As an example, the service types involved in this application include public network service A and private network service B.

After the first access network device obtains the service type of each service in at least one service, the first access network device determines the service having public network service A as a first service; the first access network device determines the service having public network service B as another first service.

Scenario 3: Service information includes both the operator information and the service type.

In this scenario, the first access network device determines that the service having the belonging operator information and the service type is the first service.

In one example, the home operators involved in this application include operator A, operator B and operator C, and the service types involved in this application include public network service D and private network service E.

After the first access network device obtains the operator information and service type of each service in at least one service, the first access network device determines that the service of operator A and public network service D is a first service; the first access network device determines that the service of operator B and public network service D is another first service; the first access network device determines that the service of operator C and public network service D is another first service; the first access network device determines that the service of operator A and public network service E is another first service; the first access network device determines that the service of operator B and public network service E is another first service; the first access network device determines that the service of operator C and public network service E is another first service.

S403: The first access network device determines a service quality parameter of at least one first service.

The service quality parameter includes at least one of the following: service guarantee rate, priority level value, packet delay budget value, and packet average delay value.

The service guarantee rate is used to characterize the service requirement for data transmission rate. The first access network device can obtain the service guarantee rate from the core network side.

The priority level value is used to indicate the priority of service resource scheduling. The smaller the priority level value, the higher the priority of resource scheduling of the service. The first access network device can obtain the priority level value (ie, the default priority level in the 5QI) from the 5QI.

The packet delay budget value is used to represent the estimated transmission delay time when transmitting data packets of a service. The first access network device can obtain the packet delay budget value (ie, the packet delay budget (Packet DelayBudget) in the 5QI) from the 5QI.

The average packet delay is used to characterize the average value of the delay generated when transmitting data packets of the service. The first access network device can obtain the average packet delay from the network management system that controls the access network device.

S404: The first access network device determines a resource allocation priority factor for each first service according to a service quality parameter of each first service in at least one first service.

The resource allocation priority factor is used to represent the priority of allocating time-frequency resources to the first service.

In a possible implementation, the resource allocation priority factor may satisfy the following formula 1:

Wherein, i is the i-th first service in at least one first service. i is a positive integer. _{Qu i} is the resource allocation priority factor of the i-th first service. _Gi is the rate guarantee factor of the i-th first service. _Dbi is the packet delay budget value of the i-th first service. DELAY _i is the average packet delay value of the i-th first service within the period. _{Pl i} is the priority level value of the i-th first service.

It should be noted that the rate guarantee factor needs to be determined by the first access network device according to the service guarantee rate. The specific determination method can refer to the following formula 3, which will not be repeated here.

In another possible implementation, when the service quality parameter further includes: the number of radio resource control protocol (radioresource control, RRC) connections, the resource allocation priority factor satisfies the following formula 2:

Wherein, RRC _i is the RRC connection number of the i-th first service. N is the number of first services. i≤N, and N is a positive integer.

The number of RRC connections includes at least one of the following: the number of RRC service connections and the number of service connections with data transmission. The first access network device may obtain the number of RRC connections from a network management system that controls the access network device.

In a possible implementation, the rate guarantee factor _Gi may satisfy the following formula 3:

Wherein, Gbr _{i is} the service guarantee rate of the i-th first service.

It should be noted that there is a service guarantee rate for GBR services. However, there is no service guarantee rate for non-GBR services. Therefore, in order to calculate the rate guarantee factor of the non-GBR service, the first access network device sets the service guarantee rate of the non-GBR service to a fixed value. For example, the service guarantee rate of the non-GBR service is set to 1.

S405. The first access network device determines interference-free time-frequency resources of the first access network device.

In different scenarios, the interference-free time-frequency resources of the first access network device are different. Scenario 4 and Scenario 5 are described below respectively: Scenario 4, the first access network device is the access network device that is interfered with. Scenario 5, the first access network device is the access network device that generates interference.

Scenario 4: The first access network device is an access network device that is interfered with.

In this scenario, the interference-free time-frequency resources of the first access network device are time-frequency resources of the first access network device that are not interfered by the second access network device.

Scenario 5: The first access network device is an access network device that generates interference.

In this scenario, the non-interference time-frequency resources of the first access network device may also be time-frequency resources in the time-frequency resources of the first access network device that do not interfere with the time-frequency resources of the second access network device.

S406. The first access network device allocates non-interference time-frequency resources to a first service whose resource allocation priority factor meets a preset condition.

In a possible implementation, the first service that meets the preset condition includes: the first N services in the first queue. The first queue is a queue determined by sorting at least one first service according to a resource allocation priority factor. The value of N is determined according to the number of services allocated with non-interference time-frequency resources, and N is a positive integer.

Illustratively, Table 4 below is an arrangement of the first queue.

As shown in Table 4 below, the first queue includes 7 first services (the 7 first services are E05, E06, E03, E04, E01, E02, and E07) sorted by resource allocation priority factors, and the resource allocation priority factors corresponding to the above 7 services. The resource allocation priority factor of the first service E05 is the highest, and the resource allocation priority factor of the first service E07 is the lowest.

In this example, if the first access network device determines that the number of services allocated with interference-free time-frequency resources is 5 (i.e., the value of N is 5), the first access network device can determine that the first 5 first services in the first queue are first services that meet the preset conditions. In other words, the first access network device determines that E05, E06, E03, E04, and E01 are first services that meet the preset conditions.

Table 4

It should be noted that the specific implementation process of the above S406 can be: the first access network device first arranges at least one first service from large to small according to the time-frequency resource allocation priority factor to determine the first queue. The first access network device sequentially allocates non-interference time-frequency resources to the first services in the first queue until the non-interference time-frequency resources are allocated.

It should be noted that the execution order of the steps shown in FIG4 can be S401→S402→S403→S404→S405→S406, or S405→S402→S403→S404→S401→S406. The above two orders are only two examples of the execution order of the steps shown in FIG4. The steps shown in FIG4 can also have other execution orders, which are not limited in this application.

The present application provides a resource allocation method, in which a first access network device determines a resource allocation priority factor for each first service according to a service quality parameter, and then allocates interference-free time-frequency resources to services with larger resource allocation priority factors (i.e., more important services) according to the size of the resource allocation priority factors for each of the above-mentioned first services. In this way, the access network device allocates interference-free time-frequency resources to services with higher priority, reduces the impact of cross-interference on such important services, ensures the normal transmission of such important services, and thus improves the transmission performance of the access network device.

It should be noted that after the first access network device allocates the non-interference time-frequency resources to the first service in the first queue according to the steps recorded in S401-S406 above, there may still be some services in the first queue that are not allocated with non-interference time-frequency resources. The first access network device needs to allocate the interference time-frequency resources to the services that are not allocated with non-interference time-frequency resources.

As shown in FIG. 5 , the first access network device may allocate the interference time-frequency resources to the above-mentioned services to which the non-interference time-frequency resources are not allocated by the following methods described in S501 to S503 .

S501. A first access network device determines a second queue.

The second queue is a queue determined by the first access network device after sorting at least one second service according to the resource allocation priority factor. The second service includes at least one of the following: at least one service in the first service that is not allocated with non-interference time-frequency resources, and a service of the second access network device that is not allocated with non-interference time-frequency resources.

The process of determining the second queue by the first access network device is specifically described below:

Step 1: The first access network device determines that the service in the first queue that is not allocated with interference-free time-frequency resources is the second service.

Step 2. The second access network device also determines the third queue according to a similar process described in S401-S406 above. The third queue is a queue determined after sorting the first service in the second access network device according to the resource allocation priority factor. The second access network device allocates the interference-free time-frequency resources of the second access network device to the first service in the third queue. After this, there may still be some services in the third queue that have not been allocated interference-free time-frequency resources. The second access network device sends a first indication message to the first access network device, indicating the services in these third queues that have not been allocated interference-free time-frequency resources. After receiving the first indication message, the first access network device determines that the services indicated by the first indication message that have not been allocated interference-free time-frequency resources are also the second services.

Step three: The first access network device sorts the second service according to the resource allocation priority factors of the second service determined in steps one and two, and determines a second queue.

The second queue and the third queue are exemplarily described below.

Illustratively, Table 5 below is an arrangement of the third queue.

As shown in Table 5 below, the third queue includes 7 first services (the 7 first services are F05, F06, F03, F04, F01, F02, and F07) sorted by resource allocation priority factors, and the resource allocation priority factors corresponding to the above 7 services. The resource allocation priority factor of the first service F05 is the highest, and the resource allocation priority factor of the first service F07 is the lowest.

In this example, if the second access network device determines that the number of services allocated with non-interference time-frequency resources is 5 (i.e., the value of N is 5), the second access network device can determine that the first 5 first services in the third queue are first services that meet the preset conditions. In other words, the second access network device determines that F05, F06, F03, F04, and F01 are first services that meet the preset conditions.

Table 5

It should be noted that the first service in the first queue and the first service in the third queue have the same service information.

Illustratively, Table 6 below is an arrangement of the second queue.

As shown in Table 6 below, the second queue includes 7 second services sorted according to the resource allocation priority factor (the 7 second services are the first services (E04, E01, E02, E07)), and the services (F01, F02, F07) of the second access network device that are not allocated with interference-free time-frequency resources, and the resource allocation priority factors corresponding to the above 7 services. The resource allocation priority factor of the second service E04 is the highest, and the resource allocation priority factor of the second service F07 is the lowest.

Table 6

S502: The first access network device determines an interfering time-frequency resource pair.

The interference time-frequency resource pair includes: a first interference time-frequency resource of a first access network device, and a second interference time-frequency resource of a second access network device.

When a signal transmitted in a downlink time slot of the first access network interferes with a signal transmitted in an uplink time slot of a second access network device, the first interfering time-frequency resource interferes with the second time-frequency resource. When a signal transmitted in a downlink time slot of the second access network interferes with a signal transmitted in an uplink time slot of the first access network device, the second time-frequency resource interferes with the first time-frequency resource.

Exemplarily, the following Table 7 shows multiple interference time-frequency resource pairs.

Table 7

As shown in Table 7 above, the second interference time-frequency resource DL21 in the interference time-frequency resource pair D1 (i.e., the downlink time-frequency resource DL21 of the second access device) will interfere with the first interference time-frequency resource UL11 in the interference time-frequency resource pair D1 (the uplink time-frequency resource UL11 of the first access network device). The first interference time-frequency resource DL11 in the interference time-frequency resource pair D4 (i.e., the downlink time-frequency resource DL11 of the first access device) will interfere with the second interference time-frequency resource UL21 in the interference time-frequency resource pair D4 (the uplink time-frequency resource UL21 of the second access network device).

In a possible implementation, the specific implementation process of the above S502 may be: the second access network device determines the interference time-frequency resources (i.e., the second interference time-frequency resources) of the second access network device, and sends the second information to the first access network device. The second information is used to indicate the second interference time-frequency resources of the second access network device. The first access network device receives the second information from the second access network. The first access network device determines the interference time-frequency resources (i.e., the first interference time-frequency resources) of the first access network device, and then forms an interference time-frequency resource pair with the first interference time-frequency resources and the second interference time-frequency resources.

It should be noted that the first information and the second information may be combined into one information and sent by the first access network device, or may be sent separately by the first access network device. This application does not limit this.

S503: The first access network device allocates one of the interference time-frequency resource pairs to the second service in the second queue in sequence according to the arrangement order of the services in the second queue.

The time-frequency resources allocated to the second service are the time-frequency resources of the access network device corresponding to the second service in the interference time-frequency resource pair.

In combination with Table 5 and Table 6, illustratively, the first access network device may allocate the interference resource pair D1 in Table 6 to the second service E04 in Table 5. As can be seen from Table 4, E04 is the first service of the first access network device. Therefore, the first access network device allocates the first interference time-frequency resource UL11 in the interference resource pair D1 to the second service E04. In this case, the second interference time-frequency resource DL21 in the interference resource pair D1 is not allocated a service to avoid interference between the first interference time-frequency resource UL11 and the second interference time-frequency resource DL21.

The present application provides a resource allocation method, in which the first access network device first determines the second queue and the interference time-frequency resource pair, and then allocates one of the interference time-frequency resources of the interference time-frequency resource pair to the second service in the second queue according to the resource allocation priority factor, so that when the second service uses one of the interference time-frequency resources in the interference resource pair, the other interference time-frequency resource does not carry other services, thereby avoiding the problem of mutual interference caused by the two interference time-frequency resources in the interference time-frequency resource pair carrying services at the same time, thereby improving the transmission performance of the access network device. In addition, when the first access network device allocates the interference time-frequency resource pair to the second service in the second queue, it also allocates the interference time-frequency resource pair from large to small according to the resource allocation priority factor, so that the access network device allocates interference time-frequency resources to services with higher priority, which facilitates the priority data transmission of such services, thereby improving the transmission performance of the access network device.

It should be noted that the allocation of the non-interference time slots and the allocation of the interference time slots can be periodically performed by the first access network device. The specific execution period can be set by the first access network device according to actual conditions, and this application does not limit this.

The above FIG. 4 and FIG. 5 record the process of the first access network device allocating time-frequency resources to the service.

Before the first access network device allocates time and frequency resources to the service, it is also necessary to determine, from a set of adjacent access network devices, a second access network device that has cross-interference with the time and frequency resources of the first access network device.

As shown in FIG. 6 , the process of the first access network device determining the second access network device from the set of access network devices having a neighbor relationship may be implemented through the following S601 to S605 .

S601. A first access network device obtains uplink and downlink resource configuration information of all adjacent access network devices in a target area on each carrier.

The uplink and downlink resource configuration information includes at least one of the following: numerology parameters, subframe type, time slot information, subframe-time slot relationship, subframe-mini-slot relationship, time slot-mini-slot relationship, vacant resource information, resource configuration information, frame structure, carrier information, pattern index number, dynamic resource information, and fixed resource information. The above is only an exemplary description of the uplink and downlink resource configuration information, and the uplink and downlink resource configuration information may also include other information, which is not limited in this application.

It should be noted that the above information can be obtained through multiple channels. The above information can include at least one of the following: a broadcast channel, a control channel, a service channel, and an access channel. The above channels are only an exemplary description, and the above channels can also include other channels, which are not limited in this application.

It should be pointed out that the access network devices having a neighboring relationship refer to access network devices where the distance between the access network devices is less than a preset value.

Alternatively, the access network devices that are in a neighboring relationship refer to access network devices whose distances are less than a preset value and whose sectors have the same coverage direction.

S602: The first access network device determines a target carrier.

The target carrier is any one of at least one carrier carried by the first access device.

Exemplarily, if the first access network device can carry two carriers (ie, carrier A and carrier B), in this case, the first access network device can determine carrier A as the target carrier, and can also determine carrier B as the target carrier.

S603: The first access network device determines a set of target access network devices from all the acquired access network devices having a neighbor relationship in the target area.

The target access network device is an access network device that supports the target carrier.

S604: The first access network device determines uplink and downlink resource configuration information of each target access network device in the set of target access network devices.

S605: The first access network device determines a second access network device from the set of target access network devices.

The second access network device is an access network device that interferes with the first access network device.

Exemplarily, the first access network device determines the frame structure (frame A1) of the target carrier (carrier A) of the first access network device according to the uplink and downlink resource configuration information. The first access network device determines the frame structure (frame A2) of the target carrier (carrier A) of the target access network device according to the uplink and downlink resource configuration information. As can be seen from Table 8 below, the value of the uplink time slot of frame A1 is 4, and the value of the downlink time slot is 6; the value of the uplink time slot of frame A2 is 7, and the value of the downlink time slot is 3. In this case, the first access network device can determine that the three uplink time slots in frame A2 will be interfered with by the three downlink time slots in frame A1 (that is, the downlink time slot DL12 will interfere with the uplink time slot UL22; the downlink time slot DL13 will interfere with the uplink time slot UL23; the downlink time slot DL17 will interfere with the uplink time slot UL27), so the first access network device determines that the target access network device is the second access network device.

Table 8

It should be noted that, when the first access network device determines that there are multiple second target access network devices, they can be allocated in sequence according to the above actions.

The present application provides a resource allocation method, in which a first access network device determines a second access network device with interference among multiple adjacent access network devices in a specified area according to uplink and downlink configuration information. In this case, not only are the interference-free time-frequency resources of the first access network device preferentially allocated to services with a larger resource allocation priority factor, and the interference time-frequency resources of the second access network device are preferentially allocated to services with a larger resource allocation priority factor, but also the interference time-frequency resources are allocated in the form of resource pairs to services in the first access network device and the second access network device that are not allocated with interference-free time-frequency resources, so that services in the first access network device and the second access network device that are not allocated with interference-free time-frequency resources only use one resource in the interference time-frequency resource pair for data transmission, thereby effectively improving the transmission performance of the access network device.

It should be noted that the above embodiments are all described by taking the first access network device as an example. In the actual process, the second access network device can also allocate non-interference time-frequency resources and/or interference time-frequency resources to the services in the second access device by executing S401-S401 in Figure 4, S501-S503 in Figure 5, and S601-S605 in Figure 6. The specific operation process of the second access network device can be understood by referring to the above embodiments, and will not be repeated here.

It is understandable that the above-mentioned resource allocation method can be implemented by a resource allocation device. In order to realize the above-mentioned functions, the resource allocation device includes hardware structures and/or software modules corresponding to the execution of each function. Those skilled in the art should easily realize that, in combination with the modules and algorithm steps of each example described in the embodiments disclosed herein, the embodiments disclosed in the present application can be implemented in the form of hardware or a combination of hardware and computer software.

There may be other division methods in actual implementation.
