Technical field

This application relates to the field of communications, and in particular to a method and device for reusing spectrum resources.

Background technique

The fifth generation of mobile communication technology (5th generation mobile networks, 5G) networks have begun to be gradually built on a large scale. High speed, low latency, and large connections are important features of 5G networks, and 5G will usher in a new era of wireless communication. 5G has a rich spectrum, ranging from 450 megahertz (MHz) to 52600MHz, and will use a lot of high-frequency spectrum. However, it is more and more difficult to obtain site sites. In the 5G era, it is expected that a large number of pole sites will be used (such as combining base stations with urban street lights). At the same time, due to 5G spectrum resources, the site density of 5G communication networks will also increase. The 5G network needs to meet the business requirements of different quality of service (Quality of Service, QOS) requirements, which will greatly increase the complexity of 5G network construction, and will also challenge the improvement of the spectrum efficiency of the overall network system. At present, most 5G pole stations are deployed in cooperation with macro base stations. In this way, the problem of co-frequency multiplexing interference will occur between macro stations and pole stations in accordance with the current spectrum reuse rules.

In order to solve this problem, the main idea of the current scheme is to avoid it, that is, some time-frequency resources are not used by the macro station, and are only used for user equipment (UE) with high interference at the pole station, while other UEs at the pole station are shared with the macro station. Spectrum resources, endure interference from macro stations.

Summary of the invention

The embodiments of the present application provide a spectrum resource multiplexing method and device, which are used to implement efficient multiplexing of spectrum resources of a macro station and a pole station.

In the first aspect, an embodiment of this application provides a spectrum resource reuse method, which is specifically used in a scenario where a macro station and a pole station are deployed together. The solution in this embodiment is described from the pole station side. The specific solution is as follows: The service model of the service to be processed; then the pole station performs real-time prediction according to the service model to obtain the spectrum resource demand information of the pole station in different time periods; then the pole station sends the spectrum resource demand information to the macro station through the interface, After the macro station receives the spectrum resource demand information, it selects available spectrum resources according to the spectrum resource demand information and spectrum resource configuration information of the pole station, where the spectrum resource configuration information is used to indicate that the spectrum resource of the pole station is the first A spectrum resource, the dedicated spectrum resource of the macro station is the second spectrum resource, wherein the macro station can share the first spectrum resource of the pole station, and the first spectrum resource and the second spectrum resource are later equal to the communication The full bandwidth spectrum of the system.

In the technical solution provided in this embodiment, the pole station predicts its own spectrum resource demand according to the service model, and enables the pole station and the macro station to select spectrum resources according to the spectrum resource demand information. For example, when the pole station business declines or becomes idle, the surplus spectrum resources are released for use by the macro station in time. When the pole station business increases, the spectrum resources of the pole station are recovered in time to ensure that the pole station is always using dedicated spectrum that is not interfered with. At the same time, the macro station can maximize the use of the shared spectrum, which effectively improves the utilization of spectrum resources. rate.

Optionally, when configuring the first spectrum resource for the pole station, the first spectrum resource may be determined according to the service requirement of the pole station. For example, during peak hours, the pole station is to guarantee the QOS of the service, and the required spectrum resource is A, then the first spectrum resource can be configured as A.

Optionally, the pole station can adopt the following methods when acquiring the business model:

In one possible implementation manner, the pole station determines the business model according to business regularity. For example, the time of a certain service has corresponding time regularity. For example, when it is at the peak from 9 am to 12 noon, the required spectrum resource is A; when it is idle from 12 o'clock to 2 pm, the required spectrum resource is B; It is at the peak between 2 pm and 6 pm, and the required spectrum resource is A; it is idle from 6 pm to 9 am, and the required spectrum resource is C. At this time, the pole station can generate a business model corresponding to the business according to the time regularity of the business. If the pole station handles multiple services, the pole station can generate different service models according to the time regularity of each service, and then count the sum of the required spectrum resources in the same time period, and then calculate the spectrum resources according to the final calculation. As spectrum resource demand information.

In another possible implementation, the pole station determines the service model based on historical services, that is, the pole station collects the historical services processed by the pole station and the spectrum resources required by the historical service, and analyzes and trains the information to obtain A business model.

Optionally, in the case that the spectrum resource of the pole station is determined, the pole station can also self-plan the spectrum resource. The specific operations are as follows:

In a possible implementation manner, the pole station receives sub-spectrum resource information, where the sub-spectrum resource information is related information of each sub-spectrum resource after the first spectrum resource is evenly divided, such as a center frequency point, etc.; The pole station scans each sub-spectrum resource after it is powered on, and obtains the receiving level of each sub-spectrum resource; finally, the pole station determines its own initial spectrum resource according to the receiving level.

Optionally, in order to avoid interference in the communication process, the pole station may select the sub-spectrum resource with the smallest receiving level as its initial spectrum resource.

In another possible implementation manner, the pole station receives sub-spectrum resource information, where the sub-spectrum resource information is related information of each sub-spectrum resource after dividing the first spectrum resource, such as a center frequency, etc.; After the pole station is powered on, it scans each sub-spectrum resource and obtains the receiving level of each sub-spectrum resource; then the pole station sends the receiving level information of each sub-spectrum resource to the centralized node, and then the centralized node Determine the appropriate sub-spectrum resource as the initial spectrum resource of the pole station; then the pole station receives the feedback information sent by the centralized node; finally, the pole station determines its own initial spectrum resource according to the feedback information.

Optionally, in order to avoid interference in the communication process, the centralized node may select the sub-spectrum resource with the smallest receiving level as the initial spectrum resource of the pole station. That is, the feedback information is used to instruct the pole station to select the sub-spectrum resource with the smallest receiving level as the initial spectrum resource.

In the technical solution provided in this embodiment, by dividing the available spectrum resources into multiple sub-spectrum resources, the pole station scans the sub-spectrum resources and selects a suitable sub-spectrum resource as the initial spectrum resource, so that the pole station spectrum self-planning can be realized , Reducing the difficulty of pole station deployment and planning, and improving the efficiency of pole station deployment.

Optionally, the specific operation of the pole station when scanning to obtain the receiving level of each sub-spectrum resource may be as follows: the pole station scans for one sub-spectrum resource in a preset period to obtain multiple receiving levels; The receiving level is directly mathematically averaged or averaged through filtering to obtain the final receiving level of the sub-spectrum resource. The pole station performs the above operations on each sub-spectrum resource, and finally obtains the reception level of each sub-spectrum resource. This can ensure that the received level obtained by scanning is a stable value, thereby ensuring the accuracy of spectrum planning.

Optionally, after the spectrum planning of the pole station is completed, when the pole station processes services, the specific operations can be as follows:

When the volume of the data packet to be sent is smaller than the preset threshold (that is, the data packet to be sent is a small packet, the preset threshold can be set according to the initial spectrum resource of the pole station, which can be used to ensure the transmission quality And the maximum data packet volume in the case of the transmission rate, or it may be smaller than the maximum data packet volume), the pole station directly uses the initial spectrum resource to send the data packet to be sent; when the volume of the data packet to be sent is greater than the pre-determined When the threshold is set, the pole station obtains the reception level of the other sub-spectrum resources in addition to the initial spectrum resource, and then selects the available sub-spectrum resources as the target sub-spectrum resources in descending order; finally, the pole station uses the The initial spectrum resource and the target sub-spectrum resource send the to-be-sent data packet. In this way, the pole station flexibly selects the spectrum resource based on service requirements, which can effectively improve the utilization rate of the spectrum resource.

It is understandable that, in this embodiment, the first spectrum resource can be allocated as a shared spectrum resource between pole stations, so that when the volume of the data packet to be sent is greater than the preset threshold, the pole station can Directly use the shared spectrum resource and the initial spectrum resource together to send the data packet to be sent; if neither the shared spectrum resource nor the initial spectrum resource can bear the data packet to be sent, the pole station scans other sub-spectrum resources , And obtain the available sub-spectrum resource together with the shared spectrum resource and the initial spectrum resource to send the to-be-sent data packet. At the same time, when the pole station acquires other sub-spectrum resources, the pole station can always maintain the corresponding frequency scan to obtain the receiving level of other sub-spectrum resources after power-on; it can also be used when the volume of the data packet to be sent is larger than the Only when the threshold is preset, the receiving level of other sub-spectrum resources is obtained by scanning.

In the second aspect, this application describes the method for obtaining the spectrum resource from the macro station side, which is specifically as follows: the macro station receives the spectrum resource demand information sent by the pole station, where the spectrum resource demand information is determined by the pole station according to the service The model is predicted; then the macro station selects the spectrum resource according to the spectrum resource demand information and the spectrum resource configuration information, where the spectrum resource configuration information is used to indicate that the spectrum resource of the pole station is the first spectrum resource, and the macro station is dedicated The spectrum resource is a second spectrum resource, where the macro station can share the first spectrum resource of the pole station, and the first spectrum resource and the second spectrum resource are later equal to the full bandwidth spectrum of the communication system.

Optionally, the specific operation of the macro station to select the spectrum resource according to the spectrum resource demand information and the spectrum configuration information may be as follows:

In a possible implementation manner, when the spectrum resource demand information indicates that the first spectrum resource is all released (that is, when the pole station is not processing services and is in an idle state), the macro station can use the first spectrum resource and the second spectrum resource. Spectrum resource; when the spectrum resource demand information indicates the release of the first spectrum resource (that is, the spectrum resource occupied by the pole station for processing services does not completely occupy the first spectrum resource), the macro station can use the second spectrum Resources and part of the spectrum resources released in the first spectrum resource; when the spectrum resource demand information indicates that the first spectrum resource is fully occupied (that is, the pole station processing service occupies all of the first spectrum resource), the macro station The second spectrum resource can be used.

In another possible implementation manner, when the spectrum resource demand information indicates that the pole station is processing services, the macro station can use the second spectrum resource; or, the macro station can use the second spectrum resource and the macro station can use the second spectrum resource. The first spectrum resource is used in the area where the station and the pole station do not overlap; when the spectrum resource demand information indicates that the pole station is in an idle state (that is, when the pole station is not processing services), the macro station can use the first spectrum resource And the second spectrum resource.

In this embodiment, the macro station can select the spectrum resources according to the time latitude or the space latitude, which effectively improves the utilization rate of the spectrum resources.

The spectrum resource multiplexing method provided in this embodiment can be applied to a deployment scenario of multiple pole stations or a deployment scenario of multiple macro stations, and its specific implementation manner may be as follows:

In the deployment scenario of multiple pole stations, each pole station is prioritized; then the corresponding spectrum resources are allocated according to the priority of the pole stations from high to low, and/or the shared spectrum resources are reserved; the pole stations notify each other For spectrum resource demand information, the pole station then determines the spectrum resource based on the spectrum resource demand information and pole station priority. The specific situation can be as follows: when a high-priority pole station needs to perform services, when the high-priority pole station uses its own spectrum resources, the shared resource can be used first; at the same time, the high-priority pole station can also Priority is given to the use of spectrum resources released by other pole stations that have not performed services. For shared spectrum resources, other poles cannot be used when performing services at high-priority pole stations. In an example, the high-priority pole station is allocated spectrum resource A, the low-priority pole station is allocated spectrum resource B, and the reserved shared spectrum resource is C. Then the specific spectrum resource allocation is as follows: When all the spectrum resource B is instructed to be released (that is, when the low-priority pole station is not processing services and is in an idle state), the high-priority pole station can use the spectrum resource A, the spectrum resource B, and the spectrum resource C; When the spectrum resource demand information indicates that a portion of the spectrum resource B is released (that is, the spectrum resource occupied by the low-priority pole station for processing services does not completely occupy the spectrum resource B), the high-priority pole station can use the spectrum resource Part of the spectrum resources released in A and the spectrum resource B and spectrum resource C; when the spectrum resource demand information indicates that the spectrum resource B is fully occupied (that is, the low-priority pole station processing service occupies all of the spectrum resource B ), the high-priority pole station can use the spectrum resource A and the spectrum resource C.

In another possible implementation manner, when the spectrum resource demand information indicates that the high-priority pole station is processing services, the low-priority pole station can use the spectrum resource B; or, the macro station can use the spectrum Resource B and use the spectrum resource C in an area where the low priority pole station and the high priority pole station do not overlap; when the spectrum resource demand information indicates that the high priority pole station is in an idle state (that is, the high priority pole station) When the priority pole station does not process services), the low priority pole station can use the spectrum resource B and the spectrum resource C.

In the deployment scenario of multiple macro stations, prioritize each macro station; prioritize each macro station; then allocate the corresponding spectrum resources according to the priority of the macro station from high to low, and/or reserve the shared spectrum Resources: The macro stations notify each other of spectrum resource demand information, and the macro station then determines the spectrum resource according to the spectrum resource demand information and the priority of the macro station. The specific situation can be as follows: when a high-priority macro station needs to perform services, the high-priority macro station can use the shared resource first when it uses its own spectrum resources; at the same time, the high-priority macro station can also Give priority to using the spectrum resources released by other macro stations that have not performed services. For shared spectrum resources, other macro stations cannot use other macro stations when performing services at high-priority macro stations. In an example, a high-priority macro station allocates spectrum resource A, a low-priority macro station allocates spectrum resource B, and the reserved shared spectrum resource is C. Then the specific spectrum resource allocation is as follows: When the spectrum resource B is instructed to be all released (that is, when the low-priority macro station is not processing services and is in an idle state), the high-priority macro station can use the spectrum resource A, the spectrum resource B, and the spectrum resource C; When the spectrum resource demand information indicates that a portion of the spectrum resource B is released (that is, the spectrum resource occupied by the low-priority macro station for processing services does not completely occupy the spectrum resource B), the high-priority macro station can use the spectrum resource Part of the spectrum resources released in A and the spectrum resource B and spectrum resource C; when the spectrum resource demand information indicates that the spectrum resource B is fully occupied (that is, the low-priority macro station processing service occupies all of the spectrum resource B ), the high-priority macro station can use the spectrum resource A and the spectrum resource C.

In another possible implementation manner, when the spectrum resource demand information indicates that the high-priority macro station is processing services, the low-priority macro station can use the spectrum resource B; or, the macro station can use the spectrum Resource B and use the spectrum resource C in an area where the low-priority macro station and the high-priority macro station do not overlap; when the spectrum resource demand information indicates that the high-priority macro station is in an idle state (that is, the high-priority macro station is idle) When the priority macro station does not process services), the low priority macro station can use the spectrum resource B and the spectrum resource C.

Detailed ways

The embodiments of the present application provide a spectrum resource multiplexing method and device, which are used to implement efficient multiplexing of spectrum resources between a macro station and a pole station.

It should be understood that the data used in this way can be interchanged under appropriate circumstances so that the embodiments described herein can be implemented in a sequence other than the content illustrated or described herein.

The fifth generation of mobile communication technology (5th generation mobile networks, 5G) networks have begun to be gradually built on a large scale. High speed, low latency, and large connections are important features of 5G networks, and 5G will usher in a new era of wireless communication. 5G has a rich spectrum, ranging from 450 megahertz (MHz) to 52600MHz, and will use a lot of high-frequency spectrum. However, it is more and more difficult to obtain site sites. In the 5G era, it is expected that a large number of pole sites will be used (such as combining base stations with urban street lights). At the same time, due to 5G spectrum resources, the site density of 5G communication networks will also increase. 5G networks need to meet the business requirements of different quality of service (Quality of Service, QOS) requirements, which will greatly increase the complexity of 5G network construction, and will also challenge the improvement of the spectrum efficiency of the overall network system. At present, most 5G pole stations are deployed in cooperation with macro base stations. In an example, as shown in Figure 1, there is an overlapping coverage area between the macro station and the pole station, and the pole station serves the corresponding business. In this way, the problem of co-frequency multiplexing interference will occur between the macro station and the pole station in accordance with the current spectrum reuse rules. In order to solve this problem, the main idea of the current plan is to avoid it, that is, some time-frequency resources are not used by the macro station, and are only used for user equipment (UE) with high interference at the pole station, while other UEs at the pole station are shared with the macro station. Spectrum resources, endure interference from macro stations.

In order to solve this problem, the embodiments of the present application provide the following technical solutions: the pole station obtains its own service model of the service to be processed; then the pole station performs real-time prediction according to the service model to obtain the spectrum resource demand of the pole station in different time periods Information; and then the pole station sends the spectrum resource demand information to the macro station through the interface. After the macro station receives the spectrum resource demand information, it selects the available spectrum according to the spectrum resource demand information and spectrum resource configuration information of the pole station Resource, where the spectrum resource configuration information is used to indicate that the spectrum resource of the pole station is the first spectrum resource, and the dedicated spectrum resource of the macro station is the second spectrum resource, wherein the macro station can share the use of the second spectrum resource of the pole station. A spectrum resource, and the first spectrum resource and the second spectrum resource afterwards are equal to the full bandwidth spectrum of the communication system.

For details, please refer to FIG. 2. In a scenario where the pole station and the macro station can communicate directly, an embodiment of the spectrum resource multiplexing method in the embodiment of the present application includes:

201. The pole station obtains service model and spectrum resource configuration information.

When the pole is working, it obtains the spectrum resource configuration information pre-configured according to the needs of the service to be processed, and the service model of its own service to be processed. Among them, the service model is used to predict the spectrum resource demand of the pole station in the next time period. In practical applications, the business model can be generated in the following ways: In one possible implementation, the pole station determines the business model according to business regularity. For example, the time of a certain service has corresponding time regularity. For example, when it is at the peak from 9 am to 12 noon, the required spectrum resource is A; when it is idle from 12 o'clock to 2 pm, the required spectrum resource is B; It is at the peak between 2 pm and 6 pm, and the required spectrum resource is A; it is idle from 6 pm to 9 am, and the required spectrum resource is C. At this time, the pole station can generate a business model corresponding to the business according to the time regularity of the business. If the pole station handles multiple services, the pole station can generate different service models according to the time regularity of each service, and then count the sum of the required spectrum resources in the same time period, and then calculate the spectrum resources according to the final calculation. As spectrum resource demand information.

The spectrum resource configuration information is used to indicate that the spectrum resource of the pole station is the first spectrum resource, and the dedicated spectrum resource of the macro station is the second spectrum resource, wherein the macro station can share and use the first spectrum resource of the pole station, Furthermore, the first spectrum resource and the second spectrum resource are equal to the full bandwidth spectrum of the communication system. When configuring the first spectrum resource for the pole station, the first spectrum resource may be determined according to the service requirements of the pole station. For example, during peak hours, the pole station is to guarantee the QOS of the service, and the required spectrum resource is A, then the first spectrum resource can be configured as A. As shown in Figure 3, the full bandwidth available to the operator in the communication system is 100 megabytes (M). According to the service situation of the pole station, 40M is allocated to the pole station as the first spectrum resource, and the remaining 60M is used as the communication The dedicated spectrum resource of the macro station in the system. The macro station can share and use the 40M spectrum resource with the pole station under appropriate circumstances.

202. The pole station predicts its own spectrum resource demand according to the service model, and generates spectrum resource demand information.

The pole station predicts its spectrum resource demand in the next time period according to the pre-acquired service model, and generates spectrum resource demand information from the spectrum resource demand. For example, the pole station determines according to the service model that the spectrum resource in the next time period needs to occupy half of the first spectrum resource to ensure that the service is performed with good service quality, then the spectrum resource demand information is used to indicate the The pole station needs to occupy half of the first spectrum resource. For example, as shown in Figure 4, the business demand of a certain company covered by pole stations, the ordinate is the business volume level, and the abscissa is the time (illustrated in a 24-hour system). It can be seen from Figure 4 that during the 8 hours from 8 o'clock to 12 o'clock and 14 o'clock to 18 o'clock, the pole station is operating at full capacity. At this time, the business volume is recorded as 4; from 12 o'clock to 14 o'clock and From 18:00 to 24:00 in the evening, the pole station is in half-load operation, and the business volume level is 2 at this time; from 0 to 8 o'clock, the pole station is in an idle state, and the business volume is recorded as 0 at this time. Assuming that the first spectrum resource allocated by the pole station is 40M, the spectrum resource demand information of the pole station can be represented as shown in Fig. 5, the pole station is in the 8-hour period from 8 o'clock to 12 o'clock and 14 o'clock to 18 o'clock. Need to use 40M spectrum; from 12 o'clock to 14 o'clock and 18 o'clock to 24 o'clock in the evening, the pole station needs to use 20M spectrum, may release 20M spectrum resources; from 0 o'clock to 8 o'clock, the pole station does not need spectrum, you can Release all 40M of the first spectrum resource.

203. The pole station sends the spectrum resource demand information to the macro station.

The pole station sends the spectrum resource demand information to the macro station through the corresponding interface. Among them, the interface can be an X2 interface or an F1 interface. In this embodiment, as long as the pole station can exchange data with the macro station, the specific interface is not limited here.

204. The macro station selects a spectrum resource according to the spectrum resource demand information and the spectrum resource configuration information.

After the macro station receives the spectrum resource requirement information of the pole station, it determines the spectrum resource that can be used by the macro station itself according to the spectrum resource requirement information and the spectrum resource configuration information. The specific operation can be as follows:

In a possible implementation manner, when the spectrum resource demand information indicates that the first spectrum resource is all released (that is, when the pole station is not processing services and is in an idle state), the macro station can use the first spectrum resource and the second spectrum resource. Spectrum resource; when the spectrum resource demand information indicates the release of the first spectrum resource (that is, the spectrum resource occupied by the pole station for processing services does not completely occupy the first spectrum resource), the macro station can use the second spectrum Resources and part of the spectrum resources released in the first spectrum resource; when the spectrum resource demand information indicates that the first spectrum resource is fully occupied (that is, the pole station processing service occupies all of the first spectrum resource), the macro station The second spectrum resource can be used. For example, as shown in Figure 3 and Figure 5, the macro station can use the dedicated 60M spectrum during the 8 hours from 8 o'clock to 12 o'clock and 14 o'clock to 18 o'clock; from 12 o'clock to 14 o'clock and 18 o'clock to 24 o'clock in the evening During this period, the macro station can use the dedicated 60M spectrum plus the 20M spectrum resources released by the pole station; during the period from 0 to 8 o'clock, the macro station can use the dedicated 60M spectrum and the 40M spectrum resources released by the pole station.

In another possible implementation manner, when the spectrum resource demand information indicates that the pole station is processing services, the macro station can use the second spectrum resource; or, the macro station can use the second spectrum resource and the macro station can use the second spectrum resource. The first spectrum resource is used in the area where the station and the pole station do not overlap; when the spectrum resource demand information indicates that the pole station is in an idle state (that is, when the pole station is not processing services), the macro station can use the first spectrum resource And the second spectrum resource. For example, as shown in Figure 3 and Figure 5, when the pole station is processing services, the macro station selects the dedicated 60M spectrum or the macro station selects the dedicated 60M spectrum, and where it does not overlap with the pole station The 40M frequency spectrum is also selected; when the pole station is not processing services, the macro station selects the full bandwidth 100M frequency spectrum.

It is understandable that when spectrum resource multiplexing is performed between the macro station and the pole station, the following method can also be used. As long as the pole station processes services, the macro station does not share the use of the first spectrum resource; When the pole station is idle, the macro station can share and use the first spectrum resource.

In this embodiment, the pole station predicts its own spectrum resource demand based on the service model, and both the pole station and the macro station select spectrum resources based on the spectrum resource demand information. For example, when the pole station business declines or becomes idle, the surplus spectrum resources are released for use by the macro station in time. When the pole station business increases, the spectrum resources of the pole station are recovered in time to ensure that the pole station is always using dedicated spectrum that is not interfered with. At the same time, the macro station can maximize the use of the shared spectrum, which effectively improves the utilization of spectrum resources. rate.

For details, please refer to FIG. 6. In a scenario where a centralized node needs to be used for communication between a pole station and a macro station, an embodiment of the spectrum resource multiplexing method in the embodiment of the present application includes:

Step 601 to step 602 are the same as step 201 to step 202 in the embodiment shown in FIG. 2 and will not be repeated here.

603. The pole station sends the spectrum resource demand information to the centralized node.

604. The centralized node sends the spectrum resource demand information to the macro station.

605. The macro station selects a spectrum resource according to the spectrum resource demand information and the spectrum resource configuration information.

In this embodiment, the step 605 is the same as the step 204 shown in FIG. 2 and will not be repeated here.

For details, please refer to FIG. 7. In a scenario where a centralized node needs to be used for communication between a pole station and a macro station, an embodiment of the spectrum resource multiplexing method in the embodiment of the present application includes:

Step 701 to step 703 are the same as step 601 to step 603 in the embodiment shown in FIG. 6, and will not be repeated here.

704. The centralized node calculates available spectrum resources of the macro station according to the spectrum resource demand information and the spectrum resource configuration information, and generates available spectrum resource information.

The centralized node calculates the available spectrum resources of the macro station according to the spectrum resource demand information and the spectrum resource configuration information. The details are as follows: In a possible implementation manner, when the spectrum resource demand information indicates that the first spectrum resource is all released (that is, when the pole station is not processing services and is in an idle state), the centralized node determines that the macro station can use the first spectrum resource. A spectrum resource and the second spectrum resource; when the spectrum resource demand information indicates the release of the first spectrum resource (that is, the spectrum resource occupied by the pole station for processing services does not completely occupy the first spectrum resource), the concentration The node determines that the macro station can use the second spectrum resource and the released part of the spectrum resource in the first spectrum resource; when the spectrum resource demand information indicates that the first spectrum resource is fully occupied (that is, the pole station processing service occupies all The first spectrum resource), the centralized node determines that the macro station can use the second spectrum resource. For example, in combination with Figure 3 and Figure 5, the centralized node determines that the macro station can use the dedicated 60M spectrum during the 8-hour period from 8 o'clock to 12 o'clock and 14 o'clock to 18 o'clock; from 12 o'clock to 14 o'clock and 18 o'clock in the evening. During the period from 0 to 24:00, the centralized node determines that the macro station can use the dedicated 60M spectrum plus the 20M spectrum resources released by the pole station; from 0 to 8 o’clock, the centralized node determines that the macro station can use the dedicated 60M spectrum. The spectrum and the 40M spectrum resources released by the pole station.

In another possible implementation manner, when the spectrum resource demand information indicates that the pole station is processing services, the centralized node determines that the macro station can use the second spectrum resource; or, the centralized node determines that the macro station can use the second spectrum resource. The second spectrum resource and the use of the first spectrum resource in the area where the macro station and the pole station do not overlap; when the spectrum resource demand information indicates that the pole station is in an idle state (that is, when the pole station is not processing services), the centralized The node determines that the macro station can use the first spectrum resource and the second spectrum resource. For example, as shown in Figure 3 and Figure 5, when the pole station processes services, the centralized node determines that the macro station selects the dedicated 60M spectrum or the centralized node determines that the macro station selects the dedicated 60M spectrum, and The 40M spectrum is also selected where it does not overlap with the pole station; when the pole station is not processing services, the centralized node determines that the macro station selects the full-bandwidth 100M spectrum.

It is understandable that when spectrum resource multiplexing is performed between the macro station and the pole station, the following method can also be used. As long as the pole station processes services, the centralized node determines that the macro station does not share the use of the first spectrum. Resources; only when the pole station is idle, the centralized node determines that the macro station can share and use the first spectrum resource.

After the centralized node calculates the available spectrum resource of the macro station, it generates available spectrum resource information so that the centralized node can send the available spectrum resource information to the macro station.

It can be understood that the relationship between the centralized node and the macro station and the pole station may be a relationship between a centralized unit (CU) and a distributed unit (DU). That is, the centralized node is a CU, and the macro station and the pole station are two different DUs.

705. The centralized node sends the available spectrum resource information to the macro station.

706. The macro station selects a spectrum resource according to the available spectrum resource information.

Based on the above solution, if multiple pole stations are deployed, since the pole stations have a small coverage area and limited business volume, it is usually not necessary to use the full 5G bandwidth, so the pole stations can only use part of the 5G bandwidth. This requires special frequency planning for pole stations. However, in the current planning scheme, the planned site usually does not have the conditions for the deployment of pole stations. When the pole station is actually deployed, the site must be adjusted. If the site is adjusted, it will affect the effect of the frequency planning of the pole station. Theoretically, after the site is adjusted, frequency planning must be re-executed. In the 5G era, pole stations are often used to cover blindness and absorb hotspot capacity. The deployment and adjustment of pole stations will be more frequent. Every time a pole station is deployed or the site is adjusted, frequency planning is carried out. The workload is large, the efficiency is low, and the cost is high. high. Therefore, in the multi-pole station deployment scenario as shown in FIG. 8, the pole station can also implement spectrum resource self-planning. For details, please refer to FIG. 9. An embodiment of the spectrum resource self-planning method in the embodiment of the present application includes :

901. The pole station obtains sub-spectrum resource information, where the sub-spectrum resource information is used to indicate information about each sub-spectrum resource in the sub-spectrum resource set after the first spectrum resource is divided.

According to the spectrum resource configuration information, it can be known that the pole station has a correspondingly allocated first spectrum resource. In this embodiment, the first spectrum resource is divided to obtain multiple sub-spectrum resources; then the pole station obtains related information of the multiple sub-spectrum resources, such as the center frequency point of each sub-spectrum resource. In this way, the pole station can know which sub-spectrum resources it can configure on itself, and can also know the possible working sub-spectrum resources of other pole stations, as well as information such as the center frequency of the working sub-spectrum resources. As shown in FIG. 10, assuming that the first spectrum resource is 40M, the 40M can be divided into 5M for each sub-spectrum resource, which can be divided into 8 sub-spectrum resources.

902. The pole station scans to obtain the reception level of each sub-spectrum resource.

When the pole station is in working state (that is, the pole station is powered on), the pole station can scan the receiving level of each sub-spectrum resource in real time (the receiving level here is used to indicate that the sub-spectrum resource is relative to the pole station. In the case of interference, the smaller the receiving level, the smaller the interference, and the larger the receiving level, the greater the interference).

In this embodiment, the specific operation of the pole station when scanning to obtain the receiving level of each sub-spectrum resource may be as follows: the pole station scans for a sub-spectrum resource in a preset period to obtain multiple receiving levels; The received level is directly mathematically averaged or averaged through filtering to obtain the final received level of the sub-spectrum resource. The pole station performs the above operations on each sub-spectrum resource, and finally obtains the reception level of each sub-spectrum resource. This can ensure that the received level obtained by scanning is a stable value, thereby ensuring the accuracy of spectrum planning. For example, if the preset week is 1 minute, the pole station may obtain N reception levels for a sub-spectrum resource within 1 minute, and then average the N reception levels to obtain the final reception level. As the receiving level of this sub-spectrum resource.

903. The pole station determines its own initial spectrum resource according to the receiving level.

After the pole station scans and obtains the reception level of each sub-spectrum resource, it configures its own initial spectrum resource according to the reception level. In this embodiment, in order to better avoid interference, the pole station may select the sub-spectrum resource with the smallest receiving level as its initial spectrum resource.

In this embodiment, after the spectrum planning of the pole station is completed, when the pole station processes services, the specific operation can be as shown in Figure 11:

When the volume of the data packet to be sent is smaller than the preset threshold (that is, the data packet to be sent is a small packet, the preset threshold can be set according to the initial spectrum resource of the pole station, that is, the preset threshold can be the use of the initial spectrum The maximum data packet volume under the condition that the resource guarantees the transmission quality and the transmission rate may also be smaller than the maximum data packet volume), the pole station directly uses the initial spectrum resource to send the data packet to be sent; When the volume is greater than the preset threshold, the pole station obtains the reception level of other sub-spectrum resources in addition to the initial spectrum resource, and then selects the available sub-spectrum resources as the target sub-spectrum resources in ascending order (understandably) However, the spectrum resource acquired by the pole station only needs to ensure the transmission quality and transmission rate of the data packet to be sent. For example, if the spectrum resource required to send the data packet to be sent is 10M, the pole station can only Select the sub-spectrum resource with the lowest received level among the remaining sub-spectrum resources as the target sub-spectrum resource; if the spectrum resource required to send the to-be-sent data packet is 13M, the pole station can select the remaining sub-spectrum resources according to the received Two sub-spectrum resources are selected as the target sub-spectrum resources in the order of the level from small to large; finally, the pole station uses the initial spectrum resource and the target sub-spectrum resource to send the data packet to be sent. In this way, the pole station flexibly selects the spectrum resource based on service requirements, which can effectively improve the utilization rate of the spectrum resource.

It is understandable that the pole station can plan the spectrum resource by itself, or send the received level obtained by the scan to the centralized node, so that the centralized node configures the initial spectrum resource for the pole station according to the received level. The operation of the centralized node to plan the initial spectrum resource for the pole station is the same as that of the pole station, and will not be repeated here.

It can be understood that the technical solutions shown in Figs. 8 to 9 can be used in combination with the technical solutions shown in Figs. 2 to 7 or can be used independently. The specific circumstances are not limited here.

In this embodiment, by dividing the available spectrum resources into multiple sub-spectrum resources, the pole station scans the sub-spectrum resources, and selects a suitable sub-spectrum resource as the initial spectrum resource. In this way, the pole station spectrum self-planning can be realized and the pole station is reduced. The difficulty of station deployment and planning improves the efficiency of pole station deployment.
