Technical Field

[0001] The embodiments of the present invention relate to the field of wireless communication technology, and in particular to a channel resource allocation method, device, base station and medium for spectrum sharing. Background Art

[0002] Nowadays, the spectrum occupied by Long Term Evolution (LTE) has been deployed commercially on a large scale. 5GNR (New Radio) is a global 5G standard based on OFDM and a new air interface design. It will be a very important foundation for the next generation of cellular mobile technology, with ultra-low latency and high reliability. How to recultivate the golden frequency bands occupied by LTE and solve the demand for the use of spectrum resources, so that the existing spectrum can be used to quickly deploy 5GNR to meet the introduction of new 5G technologies and brand promotion of operators, has brought new challenges to global network operators.

[0003] Dynamic spectrum sharing technology (full name in English: Dynamic Spectrum Sharing, abbreviated as DSS) can provide operators with a good solution to improve the utilization of spectrum resources and realize LTE and NR shared spectrum. Dynamic spectrum sharing technology supports spectrum sharing based on traffic demand between 4G and 5G resources, and can quickly complete spectrum allocation. Through this technology, network operators can dynamically share spectrum between 4G and 5G, and can deploy 5G services more economically and efficiently. However, after the shared spectrum is realized, there is usually unreasonable allocation of channel resources, which leads to the inability to fully utilize the shared spectrum resources and low utilization of shared spectrum resources. Therefore, how to reasonably allocate channel resources and improve the utilization of shared spectrum has become an urgent problem to be solved. Summary of the invention

[0004] The purpose of one or more embodiments of the present specification is to provide a channel resource allocation method, device, base station and medium for spectrum sharing, which can allocate channel resources on demand and improve the utilization rate of shared spectrum.

[0005] To solve the above technical problems, one or more embodiments of this specification are implemented as follows:

[0006] In a first aspect, a channel resource allocation method for spectrum sharing is provided, the method comprising: counting resource occupancy requirements of a first network system and a second network system for a shared channel according to business requirements; and adjusting a first resource configuration of the first network system for the shared channel and a second resource configuration of the second network system for the shared channel based on the resource occupancy requirements.

[0007] In the second aspect, a channel resource allocation device for spectrum sharing is proposed, and the device includes: a demand statistics module, used to count the resource occupancy demands of the first network system and the second network system for the shared channel according to business demand; a resource adjustment module, used to adjust the first resource configuration of the shared channel by the first network system and the second resource configuration of the shared channel by the second network system based on the resource occupancy demand.

[0008] In a third aspect, a base station is proposed, wherein the base station includes the channel resource allocation device for spectrum sharing as described above.

[0009] In a fourth aspect, a storage medium is proposed for computer-readable storage, wherein the storage medium stores one or more programs, and when the one or more programs can be executed by one or more processors, the steps of the channel resource allocation method for spectrum sharing as described above are implemented.

[0010] It can be seen from the technical solutions provided by one or more embodiments of the present specification that in the channel resource allocation method for spectrum sharing provided by the embodiment of the present invention, the resource occupation requirements of the first network system and the second network system for the shared channel are respectively counted according to business needs. The first network system and the second network system are network systems of different standards, and the shared channel resources need to be allocated when sharing the spectrum. When allocating, firstly, the resource occupation requirements of each network system for the shared channel are counted according to the business needs of the first network system and the second network system, and then the first resource configuration of the shared channel by the first network system and the second resource configuration of the shared channel by the second network system are adjusted based on the resource occupation requirements, so that the first resource configuration and the second resource configuration of the shared channel by the first network system and the second network system can be allocated in real time according to business needs. Therefore, the shared spectrum can be deployed more flexibly and dynamically, avoiding the problem of low spectrum utilization due to unreasonable channel resource allocation, improving the utilization of the shared spectrum, and improving the stability and robustness of spectrum sharing deployment.

[0022] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in one or more embodiments of this specification will be clearly and completely described below in conjunction with the drawings in one or more embodiments of this specification. Obviously, the one or more embodiments described are only part of the embodiments of this specification, not all of the embodiments. Based on one or more embodiments in this specification, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of this document.

[0023] A channel resource allocation method for spectrum sharing provided in an embodiment of the present invention is applicable to spectrum sharing technology, especially in dynamic shared spectrum, by allocating shared channel resources on demand to network systems of different standards supported simultaneously, so as to meet the business needs of network systems of different standards and improve the utilization rate of shared spectrum.

[0024] It should be noted that the channel resources in the channel resource allocation method for spectrum sharing provided in the embodiment of the present invention may at least include frequency domain resources. The channel resource allocation method for spectrum sharing provided in this specification and its various steps will be described in detail below.

[0025] Embodiment 1

[0026] Reference Figure 1 As shown, it is a schematic diagram of the steps of a channel resource allocation method for spectrum sharing provided by an embodiment of the present invention. It can be understood that the channel resource allocation method for spectrum sharing provided by an embodiment of the present invention is applicable to the allocation of channel resources when two network systems of different standards share spectrum. The channel resource allocation method for spectrum sharing includes the following steps:

[0027] Step 10: Counting resource occupation requirements of the first network system and the second network system for the shared channel respectively according to service requirements;

[0028] The resource occupancy demand of the first network system for the shared channel is counted according to the business demand of the first network system, and the resource occupancy demand of the second network system for the shared channel is counted according to the business demand of the second network system. The purpose is to adjust the original resource configuration of the shared channel based on the resource occupancy demand of the first network system and the second network system for the shared channel respectively, so that the shared channel works according to the adjusted resource configuration, which solves the resource occupancy demand of the first network system and the second network system and meets the business needs of the first network system and the second network system respectively.

[0029] In the prior art, unreasonable channel resource allocation strategies lead to insufficient spectrum resource utilization, and how channel resources are allocated becomes a bottleneck restricting shared spectrum resources. The channel resource allocation method for spectrum sharing provided in the embodiment of the present invention can count the resource occupation requirements of the first network system and the second network system for the shared channel in real time when the service requirements change in the spectrum sharing technology, and adjust the original resource configuration of the shared channel according to the service requirements of the network systems of different standards, so as to meet the resource occupation requirements of the spectrum between the network systems of different standards on demand, and can deploy dynamic sharing strategies more intelligently and flexibly, improve the utilization effect of the spectrum, and improve the stability and robustness of the spectrum sharing deployment.

[0030] The first network system and the second network system are network systems of different standards, for example, they can be an LTE network system and an NR network system, or they can be network systems of other standards, which are not limited here.

[0031] Step 20: Adjust the first resource configuration of the first network system for the shared channel and the second resource configuration of the second network system for the shared channel based on the resource occupation requirement.

[0032] The first resource configuration may be the first resource configuration actually completed in advance for the shared channel by the first network system, and the second resource configuration may be the second resource configuration actually completed in advance for the shared channel by the second network system. After the resource occupancy requirements of the two different standard network systems for the shared channel are respectively calculated according to the business requirements of the first network system and the second network system, the first resource configuration and the second resource configuration may be adjusted respectively based on the resource occupancy requirements.

[0033] When the first resource configuration and the second resource configuration are configured for the shared channel for the first time, the first resource configuration and the second resource configuration may also be text descriptions in the sharing strategy. When the first configuration is performed, the descriptions of the first resource configuration and the second resource configuration in the sharing strategy may be adjusted according to resource occupation requirements. The adjusted first resource configuration and the second resource configuration are then performed on the shared channel.

[0034] The first resource configuration of the first network system for the shared channel can meet the resource occupation demand of the first network system for the shared channel, thereby solving the business demand of the first network system; accordingly, the second resource configuration of the second network system for the shared channel can meet the resource occupation demand of the second network system for the shared channel, thereby solving the business demand of the second network system. Therefore, when business demand arises, the resource occupation demand of the shared channel of the different standard network systems of the shared spectrum can be adjusted according to the resource occupation demand corresponding to the business demand, and then the second resource configuration and the second resource configuration of the shared channel of the different standard network systems can be adjusted, thereby realizing the on-demand adjustment of the resource configuration of the shared channel, satisfying the business demand of the shared spectrum of the different standard network systems, and improving the utilization rate of the shared spectrum.

[0035] Of course, the spectrum sharing technology may include more than two network systems of different standards, and the principle of channel resource allocation is the same, and the number of network systems of different standards is not limited here.

[0036] Reference Figure 2 As shown, in some embodiments, before step 10: counting the resource occupation requirements of the first network system and the second network system for the shared channel according to the service requirements, the channel resource allocation method provided by the embodiment of the present invention further includes:

[0037] Step 30: Performing a first resource configuration on a shared channel for the first network system according to a preset sharing strategy, and performing a second resource configuration on the shared channel for the second network system;

[0038] In spectrum sharing technology, network systems of different standards can reach a sharing strategy for spectrum sharing, and network systems of different standards share the spectrum based on the sharing strategy. Therefore, in some embodiments, before the resource occupation requirements of the first network system and the second network system for the shared channel are respectively counted according to business needs, the first resource configuration for the shared channel can be performed for the first network system according to the preset sharing strategy. When the sharing strategy defines the first resource configuration for the shared channel by the first network system, if the second resource configuration for the shared channel by the second network system is also defined, the second network system can perform the second resource configuration for the shared channel based on the sharing strategy. Of course, the first resource configuration and the second resource configuration are based on the resource occupation requirements of the respective network systems for the shared channel.

[0039] It should be noted that the first resource configuration may be time domain resources or frequency domain resources, or time-frequency resources, and the second resource configuration may also be time domain resources or frequency domain resources, or time-frequency resources.

[0040] Reference Figure 3 As shown, in some embodiments, the channel resource allocation method provided by the embodiment of the present invention, step 30: performing a first resource configuration on a shared channel for a first network system according to a preset sharing strategy, and performing a second resource configuration on a shared channel for a second network system, specifically includes:

[0041] Step 300: Perform a first time-frequency resource configuration on a shared channel for a first network system, and perform a second time-frequency resource configuration on a shared channel for a second network system.

[0042] In the channel resource allocation method provided in an embodiment of the present invention, the first resource may be a time domain resource and a frequency domain resource, and the second resource may also be a time domain resource and a frequency domain resource. Therefore, performing the first resource configuration for the shared channel for the first network system according to the preset sharing strategy may be performing the first time-frequency resource configuration for the shared channel, and correspondingly, performing the second time-frequency resource configuration for the shared channel for the second network system may be performing the second time-frequency resource configuration for the shared channel.

[0043] It should be noted that the first time-frequency resource configuration and the second time-frequency resource configuration for the shared channel require that the shared channel support the implementation and sharing of time-frequency resources. Therefore, when adjusting the first resource configuration of the shared channel by the first network system and the second resource configuration of the shared channel by the second network system based on resource occupancy requirements, it is necessary to consider the adjustment of time domain resources and the adjustment of frequency domain resources at the same time to improve the utilization rate of spectrum resources.

[0044] In the embodiment of the present invention, a shared channel is a physical downlink control channel PDCCH (full name in English: Physical Downlink Control Channel), the first network system is an LTE network system, and the second network system is an NR network system for channel resource allocation as an example for explanation.

[0045] In the first step, the LTE network system completes the channel resource configuration of the physical control format indicator channel PCFICH (Physical Control Format Indicator Channel) and the first time-frequency resource configuration of the PDCCH according to the preset sharing strategy;

[0046] In the second step, the NR network system completes the second time-frequency resource configuration corresponding to the PDCCH. The NR network system can complete the second time-frequency resource configuration of the NR network system for the PDCCH according to the sharing strategy and the configuration result of the first time-frequency resource of the other LTE network system shared. The configuration result of the first time-frequency resource and the configuration result of the second time-frequency resource are in the same time domain interval, with the purpose of improving the utilization rate of spectrum sharing and solving the problem of insufficient spectrum utilization.

[0047] In the third step, the NR network system and the LTE network system each count the resource occupation requirements for the shared channel according to service requirements;

[0048] The fourth step is to adjust the first time-frequency resource configuration and the second time-frequency resource configuration for the PDCCH according to the resource occupation requirement.

[0049] Reference Figure 4 As shown, in some embodiments, in the channel resource allocation method provided in the embodiment of the present invention, the first network system is an LTE network system, the second network system is an NR network system, and the shared channel includes a physical downlink control channel PDCCH. Step 10: According to the service requirements, the resource occupation requirements of the first network system and the second network system for the shared channel are respectively counted, specifically including:

[0050] Step 100: Count the number of time domain symbols and the number of frequency domain symbols occupied by PDCCH in the LTE network system and the NR network respectively.

[0051] In the channel resource allocation method provided in an embodiment of the present invention, the first network system is an LTE network system, the second network system is an NR network system, and the shared channel is a PDCCH (Physical Downlink Control Channel) that can support time-frequency resource sharing. Therefore, an embodiment of the present invention is a method for allocating channel resources of a PDCCH.

[0052] PDCCH is a key channel for implementing spectrum sharing technology. Since it can support the sharing of both time domain resources and frequency domain resources, the channel resources will be underutilized during sharing due to the need to adjust the above two resources, and spectrum sharing cannot be maximized. In the channel resource allocation method provided in the embodiment of the present invention, the resource occupancy requirements of the first network system and the second network system for spectrum sharing on the shared channel can be counted separately according to business needs, so that the time and frequency resource configuration of the shared channel can be adjusted as needed to the maximum extent.

[0053] In the channel resource allocation method for spectrum sharing provided in an embodiment of the present invention, when the shared channel is PDCCH, the first network system is an LTE network system, and the second network system is an NR network system, the LTE network system configures the channel resources of the physical control format indicator channel PCFICH (full name: Physical Control Format Indicator Channel) and the first resource configuration of the PDCCH according to the sharing strategy; the NR network system completes the second resource configuration of the NR network system for the PDCCH based on the first resource configuration of the LTE network system for PCFICH and PDCCH under the premise of the sharing strategy; then, the resource occupancy requirements of the LTE network system and the NR network system for the time domain symbols, the number of time domain symbols, the frequency domain, the number of frequency domains, etc. occupied by the PDCCH are respectively counted; based on the resource occupancy requirements, the number of time domain symbols and the number of frequency domains occupied by the LTE network system and the NR network system for the PDCCH are adjusted.

[0054] Reference Figure 5 As shown, in some embodiments, the channel resource allocation method provided by the embodiment of the present invention, when the shared channel includes a physical downlink control channel PDCCH, step 30: performing a first resource configuration on the shared channel for the first network system according to a preset sharing strategy, and performing a second resource configuration on the shared channel for the second network system, specifically includes:

[0055] Step 310: Without exceeding the search upper limit of the PDCCH, configure a multi-symbol user equipment UE-specific search space for the PDCCH for the NR network system.

[0056] In the channel resource allocation method provided by an embodiment of the present invention, when the second resource configuration is performed on the shared channel for the second network system according to the preset sharing strategy, a multi-symbol UE-specific search space can be configured for the NR network system without exceeding the PDDCH search upper limit.

[0057] The sharing strategy may be the current definition of spectrum sharing rules by protocol in spectrum sharing. Some improvements may be made to the channel resource allocation method provided in the embodiment of the present invention, such as configuring a multi-symbol user equipment UE-specific search space for PDCCH for the NR network system mentioned in the embodiment of the present invention.

[0058] Reference Figure 6 As shown, in some embodiments, the channel resource allocation method provided by the embodiment of the present invention, step 10: counting the resource occupation requirements of the first network system and the second network system for the shared channel according to the service requirements, specifically includes:

[0059] Step 110: For the scheduling requirements of the periodic services of the NR network system, the time slot requirements of the periodic services for periodic scheduling of the PDCCH are counted;

[0060] For example, the basic public scheduling of the NR network system belongs to periodic services. To count the scheduling requirements of such periodic services, it is necessary to count the time slot requirements of the periodic services for periodic scheduling of PDCCH.

[0061] Correspondingly, step 20: adjusting the first resource configuration of the first network system for the shared channel and the second resource configuration of the second network system for the shared channel based on the resource occupation requirement specifically includes:

[0062] Step 210: For the time slot requirements of periodic services, time-frequency resources are adjusted by configuring multicast subframes.

[0063] In response to the time slot requirements of periodic services in LTE and NR network systems, the time and frequency resources are adjusted by configuring multicast subframes.

[0064] Reference Figure 7 As shown, in some embodiments, the channel resource allocation method provided by the embodiment of the present invention, step 10: counting the resource occupation requirements of the first network system and the second network system for the shared channel according to the service requirements, specifically includes:

[0065] Step 120: establishing corresponding service types for random access response RAR (full name in English: Random Access Response) and radio resource control RRC (full name in English: Radio Resource Control), and counting the time slot requirements for event-based scheduling of PDCCH by service types;

[0066] Optionally, corresponding service types are established for RAR and RRC, and the time slot requirements for event-based scheduling of PDCCH by the service types are counted.

[0067] Correspondingly, step 20: adjusting the first resource configuration of the first network system for the shared channel and the second resource configuration of the second network system for the shared channel based on the resource occupation requirement specifically includes:

[0068] Step 220: For the time slot requirements of event-type scheduling, the NR network system scheduling is delayed by configuring multicast subframes through the LTE network system to adjust the time and frequency resources of the PDCCH.

[0069] Optionally, for RAR and RRC establishment type data, the NR network system scheduling is delayed by configuring multicast subframes through the LTE network system, thereby adjusting the time and frequency resources of the PDCCH.

[0070] Reference Figure 8 As shown, in some embodiments, the channel resource allocation method provided by the embodiment of the present invention, step 10: counting the resource occupation requirements of the first network system and the second network system for the shared channel according to the service requirements, specifically includes:

[0071] Step 130: For the scheduling requirements of uplink service scheduling and downlink service scheduling of the NR network system, the occupancy requirements of the service interval of the uplink service scheduling and the service interval of the downlink service scheduling for the PDCCH are counted respectively;

[0072] According to the scheduling requirements of uplink service scheduling and downlink service scheduling of the NR network system, the occupancy requirements of the service intervals of uplink service scheduling and downlink service scheduling for PDCCH are counted.

[0073] Correspondingly, step 20: adjusting the first resource configuration of the first network system for the shared channel and the second resource configuration of the second network system for the shared channel based on the resource occupation requirement specifically includes:

[0074] Step 230: In response to the occupancy requirements of the service interval, the PDCCH channels are centrally allocated by configuring the time interval K0 between sending the downlink scheduling control information and the corresponding scheduling service information, and the time interval K2 between sending the uplink scheduling control information and the corresponding scheduling service information, so as to adjust the time-frequency resources of the PDCCH.

[0075] In response to the occupancy requirements of the service interval of the NR network system, PDCCH is centrally allocated using K0 and K2 with different configurations to complete the adjustment of the second time-frequency resources.

[0076] The channel resource allocation method for spectrum sharing provided in an embodiment of the present invention completes the channel resource configuration of the PCFICH channel and the first resource configuration of the PDCCH by the LTE network system according to the preset sharing strategy when allocating channel resources to the PDCCH, and completes the second resource configuration of the PDCCH by the NR network system according to the sharing strategy and the configuration result of the channel resource configuration by the LTE network system. Then, the resource occupation requirements of the LTE network system and the NR system for the PDCCH are counted according to their respective business requirements and link conditions; finally, the first time-frequency resource configuration and the second time-frequency resource configuration of the PDCCH by the LTE network system and the NR network system are adjusted according to the resource requirements and the sharing strategy.

[0077] From the above analysis, it can be seen that in the channel resource allocation method for spectrum sharing provided in the embodiment of the present invention, the resource occupation requirements of the first network system and the second network system for the shared channel are respectively counted according to the business requirements. The first network system and the second network system are network systems of different standards, and the shared channel resources need to be allocated when sharing the spectrum. When allocating, firstly, the resource occupation requirements of each network system for the shared channel are counted according to the business requirements of the first network system and the second network system, and then the first resource configuration of the shared channel by the first network system and the second resource configuration of the shared channel by the second network system are adjusted based on the resource occupation requirements, so that the first resource configuration and the second resource configuration of the shared channel by the first network system and the second network system can be allocated in real time according to the business requirements. Therefore, the shared spectrum can be deployed more flexibly and dynamically, avoiding the problem of low spectrum utilization due to unreasonable channel resource allocation, improving the utilization of the shared spectrum, and improving the stability and robustness of spectrum sharing deployment.

[0078] Embodiment 2

[0079] Reference Fig. 9 As shown, a channel resource allocation device 10 for spectrum sharing provided by an embodiment of the present invention includes: a demand statistics module 100 and a resource adjustment module 110. Among them:

[0080] A demand statistics module 100, used to count the resource occupation requirements of the first network system and the second network system for the shared channel according to the service requirements;

[0081] The resource occupancy demand of the first network system for the shared channel is counted according to the business demand of the first network system, and the resource occupancy demand of the second network system for the shared channel is counted according to the business demand of the second network system. The purpose is to adjust the original resource configuration of the shared channel based on the resource occupancy demand of the first network system and the second network system for the shared channel respectively, so that the shared channel works according to the adjusted resource configuration, which solves the resource occupancy demand of the first network system and the second network system and meets the business needs of the first network system and the second network system respectively.

[0082] In the prior art, unreasonable channel resource allocation strategies lead to insufficient spectrum resource utilization, and how channel resources are allocated becomes a bottleneck restricting shared spectrum resources. The channel resource allocation method for spectrum sharing provided in the embodiment of the present invention can count the resource occupation requirements of the first network system and the second network system for the shared channel in real time when the service requirements change in the spectrum sharing technology, and adjust the original resource configuration of the shared channel according to the service requirements of the network systems of different standards, so as to meet the resource occupation requirements of the spectrum between the network systems of different standards on demand, and can deploy dynamic sharing strategies more intelligently and flexibly, improve the utilization effect of the spectrum, and improve the stability and robustness of the spectrum sharing deployment.

[0083] The first network system and the second network system are network systems of different standards, for example, they can be an LTE network system and an NR network system, or they can be network systems of other standards, which are not limited here.

[0084] The resource adjustment module 110 is configured to adjust a first resource configuration of the first network system for the shared channel and a second resource configuration of the second network system for the shared channel based on resource occupation requirements.

[0085] The first resource configuration may be the first resource configuration actually completed in advance for the shared channel by the first network system, and the second resource configuration may be the second resource configuration actually completed in advance for the shared channel by the second network system. After the resource occupancy requirements of the two different standard network systems for the shared channel are respectively calculated according to the business requirements of the first network system and the second network system, the first resource configuration and the second resource configuration may be adjusted respectively based on the resource occupancy requirements.

[0086] When the first resource configuration and the second resource configuration are configured for the shared channel for the first time, the first resource configuration and the second resource configuration may also be text descriptions in the sharing strategy. When the first configuration is performed, the descriptions of the first resource configuration and the second resource configuration in the sharing strategy may be adjusted according to resource occupation requirements. The adjusted first resource configuration and the second resource configuration are then performed on the shared channel.

[0087] The first resource configuration of the first network system for the shared channel can meet the resource occupation demand of the first network system for the shared channel, thereby solving the business demand of the first network system; accordingly, the second resource configuration of the second network system for the shared channel can meet the resource occupation demand of the second network system for the shared channel, thereby solving the business demand of the second network system. Therefore, when business demand arises, the resource occupation demand of the shared channel of the different standard network systems of the shared spectrum can be adjusted according to the resource occupation demand corresponding to the business demand, and then the second resource configuration and the second resource configuration of the shared channel of the different standard network systems can be adjusted, thereby realizing the on-demand adjustment of the resource configuration of the shared channel, satisfying the business demand of the shared spectrum of the different standard network systems, and improving the utilization rate of the shared spectrum.

[0088] Of course, the spectrum sharing technology may include more than two network systems of different standards, and the principle of channel resource allocation is the same, and the number of network systems of different standards is not limited here.

[0089] Reference Fig.10 As shown, in some embodiments, the channel resource allocation device provided by the embodiment of the present invention further includes a resource configuration module 120, which is used to:

[0090] The first resource configuration is performed on the shared channel for the first network system according to a preset sharing strategy, and the second resource configuration is performed on the shared channel for the second network system.

[0091] In spectrum sharing technology, a sharing strategy for spectrum sharing can be reached between network systems of different standards, and network systems of different standards share the spectrum based on the sharing strategy. Therefore, in some embodiments, before the resource occupation requirements of the first network system and the second network system for the shared channel are respectively counted according to business needs, the first resource configuration for the shared channel can be performed for the first network system according to the preset sharing strategy. Of course, if the sharing strategy defines the first resource configuration for the shared channel by the first network system and also defines the second resource configuration for the shared channel by the second network system, the second resource configuration for the shared channel can be performed for the second network system based on the sharing strategy. Of course, the first resource configuration and the second resource configuration are based on the resource occupation requirements of the respective network systems for the shared channel.

[0092] It should be noted that the first resource configuration may be time domain resources or frequency domain resources, or time-frequency resources, and the second resource configuration may also be time domain resources or frequency domain resources, or time-frequency resources.

[0093] From the above analysis, it can be seen that in the channel resource allocation method for spectrum sharing provided in the embodiment of the present invention, the resource occupation requirements of the first network system and the second network system for the shared channel are respectively counted according to the business requirements. The first network system and the second network system are network systems of different standards, and the shared channel resources need to be allocated when sharing the spectrum. When allocating, firstly, the resource occupation requirements of each network system for the shared channel are counted according to the business requirements of the first network system and the second network system, and then the first resource configuration of the shared channel by the first network system and the second resource configuration of the shared channel by the second network system are adjusted based on the resource occupation requirements, so that the first resource configuration and the second resource configuration of the shared channel by the first network system and the second network system can be allocated in real time according to the business requirements. Therefore, the shared spectrum can be deployed more flexibly and dynamically, avoiding the problem of low spectrum utilization due to unreasonable channel resource allocation, improving the utilization of the shared spectrum, and improving the stability and robustness of spectrum sharing deployment.

[0095] The embodiment of the present invention provides a base station, and the base station includes the channel resource allocation device 10 for spectrum sharing as described above. The channel resource allocation device 10 for spectrum sharing includes: a demand statistics module 100 and a resource adjustment module 110 .

[0098] The resource occupancy demand of the first network system for the shared channel is counted according to the business demand of the first network system, and the resource occupancy demand of the second network system for the shared channel is counted according to the business demand of the second network system. The purpose is to adjust the original resource configuration of the shared channel based on the resource occupancy demand of the first network system and the second network system for the shared channel respectively, so that the shared channel works according to the adjusted resource configuration, which solves the resource occupancy demand of the first network system and the second network system and meets the business needs of the first network system and the second network system respectively.

[0099] In the prior art, unreasonable channel resource allocation strategies lead to insufficient spectrum resource utilization, and how channel resources are allocated becomes a bottleneck restricting shared spectrum resources. The channel resource allocation method for spectrum sharing provided in the embodiment of the present invention can count the resource occupation requirements of the first network system and the second network system for the shared channel in real time when the service requirements change in the spectrum sharing technology, and adjust the original resource configuration of the shared channel according to the service requirements of the network systems of different standards, so as to meet the resource occupation requirements of the spectrum between the network systems of different standards on demand, and can deploy dynamic sharing strategies more intelligently and flexibly, improve the utilization effect of the spectrum, and improve the stability and robustness of the spectrum sharing deployment.

[0100] The first network system and the second network system are network systems of different standards, for example, they can be an LTE network system and an NR network system, or they can be network systems of other standards, which are not limited here.

[0101] The resource adjustment module 110 is configured to adjust a first resource configuration of the first network system for the shared channel and a second resource configuration of the second network system for the shared channel based on resource occupation requirements.

[0102] The first resource configuration may be the first resource configuration actually completed in advance for the shared channel by the first network system, and the second resource configuration may be the second resource configuration actually completed in advance for the shared channel by the second network system. After the resource occupancy requirements of the two different standard network systems for the shared channel are respectively calculated according to the business requirements of the first network system and the second network system, the first resource configuration and the second resource configuration may be adjusted respectively based on the resource occupancy requirements.

[0103] When the first resource configuration and the second resource configuration are configured for the shared channel for the first time, the first resource configuration and the second resource configuration may also be text descriptions in the sharing strategy, and when the first configuration is performed, the descriptions of the first resource configuration and the second resource configuration in the sharing strategy may be adjusted according to resource occupation requirements. Then, the adjusted first resource configuration and the second resource configuration are performed on the shared channel.

[0104] The first resource configuration of the first network system for the shared channel can meet the resource occupation demand of the first network system for the shared channel, thereby solving the business demand of the first network system; accordingly, the second resource configuration of the second network system for the shared channel can meet the resource occupation demand of the second network system for the shared channel, thereby solving the business demand of the second network system. Therefore, when business demand arises, the resource occupation demand of the shared channel of the different standard network systems of the shared spectrum can be adjusted according to the resource occupation demand corresponding to the business demand, and then the second resource configuration and the second resource configuration of the shared channel of the different standard network systems can be adjusted, thereby realizing the on-demand adjustment of the resource configuration of the shared channel, satisfying the business demand of the shared spectrum of the different standard network systems, and improving the utilization rate of the shared spectrum.

[0105] Of course, the spectrum sharing technology may include more than two network systems of different standards, and the principle of channel resource allocation is the same, and the number of network systems of different standards is not limited here.

[0106] From the above analysis, it can be seen that in the channel resource allocation method for spectrum sharing provided in the embodiment of the present invention, the resource occupation requirements of the first network system and the second network system for the shared channel are respectively counted according to the business requirements. The first network system and the second network system are network systems of different standards, and the shared channel resources need to be allocated when sharing the spectrum. When allocating, firstly, the resource occupation requirements of each network system for the shared channel are counted according to the business requirements of the first network system and the second network system, and then the first resource configuration of the shared channel by the first network system and the second resource configuration of the shared channel by the second network system are adjusted based on the resource occupation requirements, so that the first resource configuration and the second resource configuration of the shared channel by the first network system and the second network system can be allocated in real time according to the business requirements. Therefore, the shared spectrum can be deployed more flexibly and dynamically, avoiding the problem of low spectrum utilization due to unreasonable channel resource allocation, improving the utilization of the shared spectrum, and improving the stability and robustness of spectrum sharing deployment.

[0109] Step 10: Counting resource occupation requirements of the first network system and the second network system for the shared channel respectively according to service requirements;

[0110] The resource occupancy demand of the first network system for the shared channel is counted according to the business demand of the first network system, and the resource occupancy demand of the second network system for the shared channel is counted according to the business demand of the second network system. The purpose is to adjust the original resource configuration of the shared channel based on the resource occupancy demand of the first network system and the second network system for the shared channel respectively, so that the shared channel works according to the adjusted resource configuration, which solves the resource occupancy demand of the first network system and the second network system and meets the business needs of the first network system and the second network system respectively.

[0111] In the prior art, unreasonable channel resource allocation strategies lead to insufficient spectrum resource utilization, and how channel resources are allocated becomes a bottleneck restricting shared spectrum resources. The channel resource allocation method for spectrum sharing provided in the embodiment of the present invention can count the resource occupation requirements of the first network system and the second network system for the shared channel in real time when the service requirements change in the spectrum sharing technology, and adjust the original resource configuration of the shared channel according to the service requirements of the network systems of different standards, so as to meet the resource occupation requirements of the spectrum between the network systems of different standards on demand, and can deploy dynamic sharing strategies more intelligently and flexibly, improve the utilization effect of the spectrum, and improve the stability and robustness of the spectrum sharing deployment.

[0112] The first network system and the second network system are network systems of different standards, for example, they can be an LTE network system and an NR network system, or they can be network systems of other standards, which are not limited here.

[0113] Step 20: adjusting the first resource configuration of the first network system for the shared channel and the second resource configuration of the second network system for the shared channel based on the resource occupation requirement.

[0114] The first resource configuration may be the first resource configuration actually completed in advance for the shared channel by the first network system, and the second resource configuration may be the second resource configuration actually completed in advance for the shared channel by the second network system. After the resource occupancy requirements of the two different standard network systems for the shared channel are respectively calculated according to the business requirements of the first network system and the second network system, the first resource configuration and the second resource configuration may be adjusted respectively based on the resource occupancy requirements.

[0115] When the first resource configuration and the second resource configuration are configured for the shared channel for the first time, the first resource configuration and the second resource configuration may also be text descriptions in the sharing strategy. When the first configuration is performed, the descriptions of the first resource configuration and the second resource configuration in the sharing strategy may be adjusted according to resource occupation requirements. The adjusted first resource configuration and the second resource configuration are then performed on the shared channel.

[0116] The first resource configuration of the first network system for the shared channel can meet the resource occupation demand of the first network system for the shared channel, thereby solving the business demand of the first network system; accordingly, the second resource configuration of the second network system for the shared channel can meet the resource occupation demand of the second network system for the shared channel, thereby solving the business demand of the second network system. Therefore, when business demand arises, the resource occupation demand of the shared channel of the different standard network systems of the shared spectrum can be adjusted according to the resource occupation demand corresponding to the business demand, and then the second resource configuration and the second resource configuration of the shared channel of the different standard network systems can be adjusted, thereby realizing the on-demand adjustment of the resource configuration of the shared channel, satisfying the business demand of the shared spectrum of the different standard network systems, and improving the utilization rate of the shared spectrum.

[0117] Of course, the spectrum sharing technology may include more than two network systems of different standards, and the principle of channel resource allocation is the same, and the number of network systems of different standards is not limited here.

[0118] From the above analysis, it can be seen that in the channel resource allocation method for spectrum sharing provided in the embodiment of the present invention, the resource occupation requirements of the first network system and the second network system for the shared channel are respectively counted according to the business requirements. The first network system and the second network system are network systems of different standards, and the shared channel resources need to be allocated when sharing the spectrum. When allocating, firstly, the resource occupation requirements of each network system for the shared channel are counted according to the business requirements of the first network system and the second network system, and then the first resource configuration of the shared channel by the first network system and the second resource configuration of the shared channel by the second network system are adjusted based on the resource occupation requirements, so that the first resource configuration and the second resource configuration of the shared channel by the first network system and the second network system can be allocated in real time according to the business requirements. Therefore, the shared spectrum can be deployed more flexibly and dynamically, avoiding the problem of low spectrum utilization due to unreasonable channel resource allocation, improving the utilization of the shared spectrum, and improving the stability and robustness of spectrum sharing deployment.
