Detailed ways

Exemplary embodiments of the present invention will be described below with reference to the accompanying drawings. In the interest of clarity and conciseness, not all features of an actual implementation are described in this specification. It should be understood, however, that in developing any such practical embodiment, many implementation-specific decisions must be made in order to achieve the developer's specific goals, such as meeting those constraints related to the system and business, and those Restrictions may vary from implementation to implementation. Moreover, it should also be understood that development work, while potentially complex and time-consuming, would at least be a routine undertaking for those skilled in the art having the benefit of this disclosure.

Here, it should also be noted that, in order to avoid obscuring the present invention due to unnecessary details, only the device structure and/or processing steps closely related to the solution according to the present invention are shown in the drawings, and the Other details not relevant to the present invention are described.

Fig. 1 shows a block diagram of functional modules of a spectrum management electronic device for wireless communication according to an embodiment of the present disclosure.

As shown in FIG. 1 , the spectrum management electronic device 100 includes: a processing unit 101, which can receive an application for spectrum trading from a spectrum acquisition electronic device in the subsystem of the spectrum management system to which the spectrum management electronic device 100 belongs. In the case of spectrum trading, pre-processing is carried out to protect the main system in the spectrum management system from damage caused by interference caused by spectrum trading.

Wherein, the processing unit 101 may be implemented by one or more processing circuits, and the processing circuits may be implemented as a chip, for example.

Spectrum management electronic device 100 may specifically, for example, be arranged on the side of a spectrum management device included in a spectrum management system or be communicably connected to the spectrum management device. Here, it should also be pointed out that the electronic spectrum management device 100 may be implemented at the chip level, or may also be implemented at the device level. For example, the spectrum management electronic device 100 may work as a spectrum management device itself, and may also include external devices such as memory, transceiver (not shown), and the like. The memory can be used to store programs and related data information that the base station needs to execute to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices, and the implementation form of the transceiver is not specifically limited here.

The spectrum management system according to the present disclosure may be a 5G NR (New Radio, new air interface) communication system. Further, the spectrum management system according to the present disclosure may include a non-terrestrial network (Non-terrestrial network, NTN). Optionally, the spectrum management system according to the present disclosure may further include a terrestrial network (Terrestrial network, TN). Those skilled in the art can understand that the spectrum management system according to the present disclosure can also be a 4G or 3G communication system. In addition, the spectrum management system according to the present disclosure may also be a spectrum management system of the Citizens Broadband Radio Service (CBRS) standard.

The spectrum management system may include a spectrum management electronic device 100, a primary system, and a secondary system. The spectrum management electronic device 100 is used to manage spectrum usage in the spectrum management system. The primary system is generally a military radar system, a ground satellite station, and the like. The number of primary systems can be more than one, and several electronic devices are included in the secondary systems. Spectrum trading is possible between electronic devices included in the subsystem. For example, when the spectrum acquisition electronic device in the secondary system wants to acquire the spectrum, it sends an application for spectrum trading.

In the spectrum management system, the main system has the highest spectrum usage priority. After spectrum transactions are carried out between electronic devices included in the secondary system, the use of spectrum resources will change, so the interference relationship with the primary system will also change, and the cumulative interference at the protection point of the primary system will also change accordingly.

In the case where there are multiple primary systems in the spectrum management system according to an embodiment of the present disclosure, each primary system should be protected from damage caused by interference caused by spectrum trading.

In the embodiment according to the present disclosure, the spectrum management electronic device 100 can pre-process the spectrum transaction. If the spectrum transaction causes severe interference to the primary system, the spectrum transaction will be excluded, so as to protect the communication quality of the primary system. Therefore, the spectrum management electronic device 100 can protect the primary system in the spectrum management system from damage caused by interference caused by spectrum trading, thereby ensuring the communication quality of the primary system.

Hereinafter, for convenience, the Citizens Broadband Radio Service (CBRS) standard is taken as an example to describe the spectrum management system. As an example, the spectrum management electronic device 100 includes a spectrum access system (SAS) and a coexistence manager (CxM) corresponding to each coexistence group (CxG) in the secondary system, and each CxG may include multiple electronic devices (also May be called CBSD, Citizens Broadband Radio Service Device).

The CBSD may be a base station, and the base station may be, for example, an eNB or a gNB. Specifically, for example, the CBSD may be set on the side of the base station or communicably connected to the base station. Here, it should also be pointed out that CBSD can be implemented at the chip level, or can also be implemented at the device level. For example, a CBSD may operate as a base station itself, and may also include external devices such as memory, transceivers (not shown). The memory can be used to store programs and related data information that the base station needs to execute to implement various functions. The transceiver may include one or more communication interfaces to support communication with different devices (eg, user equipment, other base stations, etc.), and the implementation form of the transceiver is not specifically limited here.

FIG. 2 is a diagram illustrating an example of a spectrum management system according to an embodiment of the present disclosure. Several CBSDs are shown in Fig. 2, all of these CBSDs constitute a subsystem, and these CBSDs belong to coexistence groups CxG-1, CxG-2 and CxG-3 respectively (in Fig. 2, for convenience, only three Coexistence group, those skilled in the art can understand that the spectrum management system can include other numbers of coexistence groups), there is potential interference between different CBSDs due to the setting of transmission parameters, and CxM-1 is a coexistence manager corresponding to CxG-1, CxM-2 is a coexistence manager corresponding to CxG-2, and CxM-3 is a coexistence manager corresponding to CxG-3. The SAS (not shown in Figure 2) has the information of the main system; each CxM has the identity information and transmission parameter information of all managed CBSDs. Each CxM is responsible for the allocation of CBSD spectrum resources in its corresponding CxG to coordinate the coexistence between CBSDs. CxM and CBSD can exchange information through the SAS-CBSD protocol. In each synchronization cycle (the longest synchronization cycle is once a day), the SASs will synchronize information, and the CxM will exchange information to coordinate and synchronize the interference relationship of CBSD. The CxM will allocate spectrum to the CBSD in the CxG. In the embodiment according to the present disclosure, it is assumed that each CBSD has been assigned a main channel, and the CBSD can expand spectrum resources in the form of spectrum trading, that is, when CBSD needs other spectrums, it can apply for spectrum trading with other CBSDs, For example, the application may contain parameters such as the frequency band to be traded, the transmit power of CBSD, and basic information. The dotted double arrows in Figure 2 indicate spectrum trading.

Those skilled in the art can understand that the spectrum management system shown in FIG. 2 is only an example, and the spectrum management system according to an embodiment of the present disclosure may be a system other than the spectrum management system shown in FIG. 2 .

For example, in the spectrum management system shown in FIG. 2 , the SAS is used to perform the above preprocessing on spectrum trading.

As an example, protecting the primary system from damage caused by interference caused by spectrum trading includes ensuring that the interference is within the tolerable range of the primary system.

As an example, protecting the primary system from damage caused by interference caused by spectrum trading includes: judging whether interference from spectrum trading to the primary system is smaller than a first predetermined threshold.

Those skilled in the art may understand that the first predetermined threshold may be preset according to experiences or application scenarios.

For example, in the spectrum management system shown in Figure 2, consider the interference protection point of the main system, and set the interference threshold (the first predetermined threshold) for the interference protection point, if the interference brought by spectrum trading to the interference protection point of the main system exceeds If the interference threshold is not exceeded, the spectrum transaction is verified as not passing, so as to ensure the communication quality of the main system.

Those skilled in the art can also think of other ways to protect the primary system from damage caused by interference caused by spectrum trading, which will not be repeated here.

As an example, the processing unit 101 may be configured to perform the above determination based on the transmission power information of the spectrum acquisition electronic device and the path loss from the spectrum acquisition electronic device to the main system.

Assuming that I _p is the interference caused by spectrum trading to the main system, P _t is the transmission power of the spectrum acquisition electronic equipment, and P _l is the path loss value from the spectrum acquisition electronic equipment to the protection point of the main system, then the interference I _p can be expressed as:

I _p =P _t -P _l +G _t +G _r

In the above formula, G _t represents the transmit antenna gain of the spectrum acquisition electronic device, and G _r represents the receive antenna gain of the spectrum providing electronic device to conduct spectrum trading with the spectrum acquisition electronic device.

As an example, the processing unit 101 may be configured to, in the case of protecting the main system from damage caused by interference caused by spectrum trading, send the application related to spectrum trading to the user in the coexistence group to which the spectrum acquisition electronic device belongs. At least one decision-making electronic device for verification of spectrum transactions. For example, in the spectrum management system shown in Figure 2, under the condition that the SAS ensures that the main system will not be damaged by interference caused by spectrum trading, the CxM corresponding to the coexistence group to which the spectrum acquisition electronic equipment belongs will The transaction application is sent to at least one decision-making electronic device for verifying the spectrum transaction in the coexistence group to which the spectrum acquisition electronic device belongs.

In the embodiment according to the present disclosure, the spectrum management electronic device 100 performs the above preprocessing and the decision-making electronic device verifies the spectrum transaction, so that the spectrum management electronic device 100 and the decision-making electronic device jointly process the spectrum transaction, which can improve Efficiency of Spectrum Trading.

As an example, the processing unit 101 may be configured to construct an interference overlap graph based on interference between electronic devices included in the secondary system, and select at least one decision-making electronic device from among the electronic devices included in the coexistence group based on the interference overlap graph.

When the decision-making electronic device verifies the spectrum transaction, the spectrum acquisition electronic device will interfere with it, and the decision-making electronic device may deny the transaction with a certain probability, that is, a selfish behavior occurs.

In an embodiment according to the present disclosure, the spectrum management electronic device 100 selects the decision-making electronic device in consideration of interference between electronic devices included in the secondary system. Considering interference and selecting decision-making electronic equipment can make decision-making electronic equipment and spectrum trading as irrelevant as possible (that is, maintain the fairness of the verification of spectrum trading), reduce the selfish behavior of decision-making electronic equipment, and thus reduce the risk caused by selfish decision-making electronic equipment. The spectrum transaction fails due to the equipment.

As an example, each node in the interference overlap graph corresponds to each electronic device included in the secondary system, and the edge formed by the connection between node i and node j in the interference overlap graph is used to represent node i and Interference relationship between nodes j: when the interference between node i and node j is less than the second predetermined threshold, the edge indicates that there is no interference between node i and node j, and the interference between node i and node j In the case of greater than or equal to the second predetermined threshold and node i and node j belong to the same coexistence group, the edge indicates that there is interference in the same group between node i and node j, and the interference between node i and node j is greater than or equal to the second predetermined threshold threshold and node i and node j belong to different coexistence groups, the edge indicates that there is cross-group interference between node i and node j, where i and j are positive integers greater than or equal to 1 and less than or equal to N, and N represents the subsystem The total number of electronic devices included in , and N is a positive integer greater than or equal to 2.

In the following description, for simplicity, node i is sometimes used to represent the electronic device corresponding to node i, and node j is used to represent the electronic device corresponding to node j.

Interference between node i and node j

It can be expressed as:

In the above formula, I _{i, j} represents the interference of node i to node j, and I _{j, i} represents the interference of node j to node i. max() means to take the maximum value.

For example, assuming that node i is a transmitting node and node j is a receiving node, I _i,j can be calculated by the following formula:

In the above formula,

Denotes the transmit antenna gain of node i,

Denotes the receiving antenna gain of node j,

Indicates the transmitting power of node i, λ indicates the wavelength, d _i,j indicates the distance between node i and node j, and α indicates the path loss coefficient.

The interference overlay graph can be expressed as:

G=<V,E>

In the above formula, G represents the interference overlap graph, V represents the node in the interference overlap graph, and E represents the edge of the interference overlap graph.

The nodes in the interference overlap graph can be expressed as:

V={v _i |i=1, 2, ..., N}

In the above formula, v _i represents node i.

The "edges" in the interference overlap graph can be expressed as:

E={e _i,j |i,j=1,2,...,N; i≠j}

In the above formula, e _{i, j} represent the interference relationship between node i and node j. According to whether node i and node j are in the same coexistence group and the size of the interference, different "edges" can be further distinguished. The mathematical expression is as follows:

Based on e _i,j corresponding to i=1,2,...,N and j=1,2,...,N, an N*N adjacency matrix can be obtained, and an interference overlap graph can be constructed based on the adjacency matrix.

It can be seen that the interference overlap graph can reflect the interference relationship between the electronic devices included in the secondary system. For example, an "edge" indicating the presence of same-group interference can reflect that the interference between node i and node j is interference between electronic devices from the same coexistence group, while an "edge" indicating the existence of cross-group interference can reflect that node i Interference with node j is interference between electronic devices from different coexistence groups.

Those skilled in the art may understand that the second predetermined threshold may be preset according to experiences or application scenarios.

For example, in the spectrum management system shown in Figure 2, in each synchronization cycle, information is synchronized between CxMs, for example, CxM will interact with other CxMs in the spectrum management system with the transmission information of the CBSD in its corresponding CxG .

If there are M (M is a positive integer greater than or equal to 2) CxGs in the spectrum management system shown in FIG. the case of M=3). In each synchronization period, the M CxMs respectively exchange the transmission information of the CBSD in the corresponding CxG with other CxMs.

For example, each CxM in CxM_1, CxM_2, ..., CxM_M can respectively construct an interference overlap map based on the interference relationship between all electronic devices included in the subsystem, or, by part of CxM_1, CxM_2, ..., CxM_M The CxM constructs an interference overlay graph based on the interference relationships among all electronic devices included in the subsystem, and sends the constructed interference overlap graph to other CxMs.

For example, each CxM in CxM_1, CxM_2, ..., CxM_M can be based on the interference relationship between electronic devices in its corresponding CxG and the interference between electronic devices in its corresponding CxG and electronic devices in neighboring GxGs In each synchronization cycle, M CxMs share these partial interference graphs to form an interference overlap graph that can reflect the interference relationship between all electronic devices in the subsystem.

Those skilled in the art can think of other forms of the interference overlay graph, which will not be repeated here.

As an example, the processing unit 101 may be configured to obtain the frequency spectrum for each electronic device k included in the coexistence group to which the electronic device belongs: find a node k corresponding to the electronic device k in the interference overlap graph, and calculate and Among the edges corresponding to node k, the first number of edges indicating the presence of same-group interference and the second number of edges indicating the existence of cross-group interference, and the ratio between the first number and the second number are greater than a third predetermined threshold In the case of , the electronic device k is selected as a candidate decision-making electronic device, and the processing unit 101 may be configured to select at least one decision-making electronic device from the candidate decision-making electronic devices corresponding to the coexistence group, wherein k is greater than or equal to 1 And a positive integer less than or equal to N.

Due to the complexity of cross-coexistence group spectrum transactions (cross-group transactions), electronic devices with more interference in the same group are more likely to initiate spectrum transactions within the same coexistence group, and electronic devices with more cross-group interference are more likely to initiate cross-coexistence group transactions. spectrum trading. Under this premise, an electronic device with a larger ratio of the same-group interference and cross-group interference has a smaller probability of applying for cross-group transactions, that is, it has less correlation with cross-group transactions, so it can be selected as a decision-making electronic device. Validation and processing of spectrum transactions. That is, considering the ratio of the same-group interference and cross-group interference received by electronic devices to select decision-making electronic devices can improve the independence of electronic devices that conduct cross-group transactions and decision-making electronic devices.

For example, the candidate decision nodes are preliminarily selected according to the quantitative relationship of "edges" in the interference overlap graph, and the expression is as follows:

In the above formula, V ^* represents the candidate decision node for preliminary selection,

Represents the first number of edges with the same group of interference among the edges corresponding to node k,

Indicates the second number of edges that represent cross-group interference among the edges corresponding to node k, and E _th represents the threshold of the "edge" ratio, that is, the third predetermined threshold.

Those skilled in the art may understand that the third predetermined threshold may be preset according to experiments or application scenarios.

Those skilled in the art can think of other ways of selecting candidate decision-making electronic devices, which will not be repeated here.

For example, in the spectrum management system shown in FIG. 2, the spectrum management electronic device corresponding to the coexistence group to which the spectrum acquisition electronic device belongs selects a candidate decision-making electronic device from the coexistence group to which the spectrum acquisition electronic device belongs based on the interference overlap graph, and At least one decision-making electronic device is selected from candidate decision-making electronic devices corresponding to the coexistence group to which the spectrum acquisition electronic device belongs. Similarly, the spectrum management electronic devices corresponding to other coexistence groups respectively select candidate decision-making electronic devices from the coexistence group based on the interference overlap graph, and select at least one decision-making electronic device from the candidate decision-making electronic devices corresponding to the coexistence group .

As an example, the processing unit 101 may be configured to select at least one decision-making electronic device based on reputation values of candidate decision-making electronic devices corresponding to the coexistence group to which the spectrum acquisition electronic device belongs.

For example, in the spectrum management system shown in FIG. 2 , the CxM corresponding to each CxG stores the transaction reputation values of the CBSDs it manages (all CBSDs in the CxG).

For the reputation value of electronic equipment, please refer to "Zhao Youping, Lu Cong, Sun Chen, Electronic equipment and method for wireless communication, computer readable storage medium, CN112954698A,

2021-06-11 ". In addition, those skilled in the art can think of other definitions of reputation value, which will not be repeated here.

The reputation value (transaction reputation value) of electronic equipment can reflect the transaction records of electronic equipment. Spectrum trading will bring changes in reputation value. The higher the reputation value, the better the transaction record of electronic equipment. Sort the primary candidate decision-making electronic devices in descending order according to the transaction reputation value, and select the candidate decision-making electronic device with a good reputation value as the decision-making electronic device.

In addition, in addition to the reputation value, those skilled in the art can think of other ways to select the decision-making electronic device from the candidate decision-making electronic devices, which will not be repeated here.

As an example, the total number of candidate decision-making electronic devices selected from all coexistence groups included in the subsystem is a third quantity, and the total number of decision-making electronic devices selected from all coexistence groups is a fourth quantity, wherein the fourth A number of decision-making electronic devices constitute a decision-making group, and the decision-making electronic devices in the decision-making group can communicate in real time. The number is set to 0, and when the third number is greater than or equal to the predetermined minimum number of decision-making electronic devices and less than the predetermined maximum number of decision-making electronic devices, the fourth number is calculated based on the third number, and when the third number is greater than or equal to the predetermined maximum number of decision-making electronic devices In the case of the number of devices, the fourth number is set as the predetermined maximum number of decision-making electronic devices.

Assume that according to the provisions in the existing standards, if CxM is used to achieve the

For spectrum trading between CBSDs, since the current interaction cycle (synchronization cycle) between CxM and SAS is at most once a day, it will lead to poor real-time performance of spectrum trading across coexistence groups, which is far from meeting the dynamic requirements. Spectrum management needs.

In the spectrum management system according to an embodiment of the present disclosure, the decision-making electronic devices selected from all coexistence groups form a decision-making group, and the decision-making electronic devices in the decision-making group can communicate in real time. Therefore, through the decision-making group in the decision-making group The real-time communication between decision-making electronic devices can carry out real-time spectrum transactions between different coexistence groups, and can meet the throughput requirements of user equipment in the scenario for large-scale spectrum transactions, that is, it can increase the number of effective spectrum transactions and Network cumulative throughput.

Assuming that N _ini is the total number of candidate decision-making electronic devices selected from all coexistence groups included in the subsystem, that is, the third quantity, and N _Dec is the total number of decision-making electronic devices selected from all coexistence groups, that is, the fourth quantity, it can be N _Dec is calculated from N _ini as follows.

In the above formula, N _min and N _max are respectively the predetermined minimum number of decision-making electronic devices and the predetermined maximum number of decision-making electronic devices. g(N _ini ) represents a manner of calculating N _Dec according to N _ini when the third number is greater than or equal to the predetermined minimum number of decision-making electronic devices and less than the predetermined maximum number of decision-making electronic devices.

Those skilled in the art can understand that the minimum number of decision-making electronic devices and the predetermined maximum number of decision-making electronic devices can be preset according to experience or application scenarios.

For example, when N _ini <N _min , that is, N _Dec is 0, the process of selecting candidate decision-making electronic devices is performed again by changing the third predetermined threshold until N _ini ≥ N _min .

For example, in the spectrum management system shown in FIG. 2, when the sum of the numbers of candidate decision-making electronic devices selected by CxM corresponding to each coexistence group is not equal to the fourth number, for example, by changing the The number of candidate decision-making electronic devices selected by the CxM corresponding to the group makes the sum of the numbers of candidate decision-making electronic devices selected by the CxM corresponding to each coexistence group equal to the fourth number.

As an example, the processing unit 101 may be configured to make the fourth number comply with the requirements of the predetermined consensus mechanism between the decision-making electronic devices when the third number is greater than or equal to the predetermined minimum number of decision-making electronic devices and less than the predetermined maximum number of decision-making electronic devices quantity.

For example, when the predetermined consensus mechanism is the Practical Byzantine Consensus Algorithm (PBFT), the number of PBFTs N_PBFT must satisfy:

N_PBFT=3f+1

In the above formula, f represents the maximum number of Byzantine fault nodes that can be tolerated, f=1,2,3..., and the complexity of the PBFT algorithm is O(N_PBFT ² ), so as the number of nodes increases, the PBFT algorithm Latency and overhead will be significantly affected.

For example, when the predetermined consensus mechanism is the above PBFT, g(N _ini ) can be expressed as:

In the above formula,

Indicates the rounding down operation.

For example, the aforementioned minimum number of decision-making electronic devices and the predetermined maximum number of decision-making electronic devices may meet the number requirements of the predetermined consensus mechanism.

As an example, the processing unit 101 may be configured to update the interference overlap map at a predetermined period, and reselect at least one decision-making electronic device based on the updated interference overlap map.

For example, the predetermined period may be the aforementioned synchronization period.

The adjustment of the emission coefficient of the electronic equipment in the spectrum management system will change the interference relationship in the spectrum management system, so updating the interference overlap map at a predetermined period can more accurately reflect the above interference relationship. In addition, reselecting at least one decision-making electronic device based on the updated interference overlap map can more accurately select a decision-making electronic device that is as irrelevant as possible to spectrum trading.

For example, decision-making electronic devices change their transaction reputation values due to processing spectrum transactions across coexistence groups; therefore, in the case of selecting decision-making electronic devices based on reputation values, decisions with good reputation values can be selected more accurately Electronic devices can reduce the number of malicious transactions caused by selfish decision-making electronic devices, thereby improving the security of spectrum transactions across coexistence groups.

As an example, the processing unit 101 may be configured to send the updated interference overlap map to at least one decision-making electronic device at a predetermined period, for the at least one decision-making electronic device to verify spectrum trading based on the updated interference overlap map.

For example, the decision-making electronic device may find at least one related electronic device related to spectrum trading based on the interference overlap graph, and verify that the interference of the spectrum trading on each of the at least one related electronic device is less than or equal to the fourth predetermined threshold Via Spectrum Trading.

For example, all decision electronics in the decision group verify spectrum trading based on the updated interference overlap map.

Those skilled in the art can imagine that the fourth predetermined threshold can be preset according to experiences or application scenarios.

Spectrum trading will cause potential co-channel interference. If spectrum trading is not verified, related electronic equipment will be seriously affected by interference after several rounds of trading. By calculating the interference received by the relevant electronic equipment by the decision-making electronic equipment, the influence of the transaction on the communication quality of the relevant electronic equipment can be avoided, and the communication quality of the relevant electronic equipment can be improved. That is to say, related electronic equipment related to spectrum trading can be protected from damage caused by interference caused by spectrum trading, and the signal-to-interference-noise ratio (SINR) of related electronic equipment can be improved.

For example, the relevant electronic device may be an electronic device that is allocated the same main channel as the frequency band involved in the spectrum transaction and interferes with the spectrum acquisition electronic device.

A set of at least one related electronic device is denoted as Q, and for each related electronic device q∈Q in the set, the decision-making electronic device is verified to pass the spectrum transaction if the following formula is satisfied:

Among them, I _{p, q} represent the interference caused by spectrum trading p to related electronic equipment q,

Indicates the fourth predetermined threshold, that is, the interference threshold caused by spectrum trading acceptable to electronic equipment.

If the interference caused by the spectrum transaction does not satisfy the above formula, that is, the spectrum transaction will have a serious impact on the electronic equipment in the system, the transaction fails.

As an example, the processing unit 101 may be configured to determine whether the application for spectrum trading meets the predetermined requirements based on the information of the spectrum acquisition electronic device before performing protection against the main system in the preprocessing, and only when it is determined that the application meets the predetermined requirements Next, the protection in the pretreatment is carried out.

Each spectrum transaction has different information, such as the identity information and emission parameters of the spectrum acquisition electronic equipment. For example, determining whether the application for spectrum trading meets the predetermined requirements may include verifying the registration information of the electronic equipment for spectrum acquisition, verifying the account balance of the electronic equipment for spectrum acquisition, verifying the historical transaction reputation value of the electronic equipment for spectrum acquisition, verifying whether the spectrum transaction information violates regulations, etc. at least one of.

For example, in the spectrum management system shown in FIG. 2 , the CxM corresponding to the CxG to which the spectrum acquisition electronic equipment belongs determines whether the application for spectrum trading meets predetermined requirements. When it is determined that the application meets the predetermined requirements, the CxM corresponding to the CxG to which the spectrum acquisition electronic equipment belongs sends the information about spectrum trading to the SAS, so that the SAS can verify the interference of the main system to protect the main system from spectrum trading. damage caused by interference. For example, information about spectrum trading may include location information of spectrum acquisition electronic equipment, frequency bands to be traded, transmission power of spectrum acquisition electronic equipment, and the like.

By performing the protection processing in the preprocessing only when the application is determined to meet the predetermined requirements, the spectrum management electronic device according to the embodiment of the present disclosure can verify the information of the spectrum acquisition electronic device in advance, and exclude unqualified spectrum transaction applications.

As an example, the coexistence group in the subsystem is a blockchain-related group, and the electronic devices in the coexistence group are nodes involved in the blockchain. For example, each coexisting group in the subsystem is a parallel blockchain. In the blockchain, a single chain can be used to conduct spectrum transactions of nodes in the same coexistence group (same blockchain), and nodes between blockchains can use the cross-chain mechanism to conduct spectrum transactions across coexistence group nodes (cross-blockchain) ( Hereinafter, sometimes simply referred to as cross-chain transactions), resource sharing between blockchains of different coexistence groups can be realized. Due to the complexity and variety of wireless communication services, when using multiple blockchains, different blockchains can be designed for different services, making spectrum management more flexible.

By making the coexistence group a group related to the blockchain, it is possible to connect blockchains designed for different communication services, improve the scalability of the blockchain, and make the blockchain more suitable for the wireless communication field.

In addition, it can realize the decentralized management of spectrum resources of base stations of different operators or spectrum management system equipment.

As an example, a decision group is a blockchain-related group, and the decision electronics in the decision group are the nodes involved in the blockchain. As described above, select nodes in each of the above-mentioned parallel blockchains (coexistence groups) to build a decision chain, and the decision chain can assist in spectrum transactions across coexistence group nodes.

The decision chain does not rely on a trusted third party, and has high flexibility and scalability, making it more suitable for multi-system, multi-application wireless network scenarios.

On the one hand, the coexistence manager corresponding to the coexistence group can jointly process cross-chain transactions with the decision-making chain to improve the efficiency of cross-chain transactions, and on the other hand, it can guarantee transactions initiated on different blockchain chains.

In the following, let the coexistence group in the spectrum management system in Fig. 2 be a blockchain for description. In the following, for convenience, the coexistence group is sometimes referred to as a coexistence chain, the electronic devices in the coexistence group are referred to as coexistence nodes, the candidate decision-making electronic devices are referred to as candidate decision-making nodes, the decision-making electronic devices are referred to as decision-making nodes, and the decision-making group is called the decision chain, the same-group interference is called the same-chain interference, and the cross-group interference is called the different-chain interference.

In FIG. 3 , it is shown that, for example, there are two coexistence chains (coexistence chain 1 and coexistence chain 2 ). CxM-1 corresponds to coexistence chain 1, and CxM-2 corresponds to coexistence chain 2. The decision-making nodes selected from coexistence chain 1 and coexistence chain 2 form a decision-making chain.

As shown in Figure 4, the subsystem includes several coexistence nodes, wherein the black coexistence nodes in the subsystem constitute the first coexistence chain, the gray coexistence nodes in the subsystem constitute the second coexistence chain, and the white coexistence nodes in the subsystem Constitute the third coexistence chain, the dotted line in the subsystem indicates that the interference between two coexisting nodes connected by a straight line is same-chain interference, and the solid line in the subsystem indicates the interference between two coexisting nodes connected by a straight line For heterochain interference. As described above in conjunction with the interference overlap graph, based on the ratio between the first number of edges indicating the existence of same-chain interference and the second number of edges indicating the existence of inter-chain interference, from the first coexistence chain, the second coexistence chain, The nodes of the decision chain are selected respectively from the third coexistence chain, and these decision chain nodes constitute the decision chain, where the dotted line with the arrow in Fig. 4 represents the mapping between the coexistence nodes in the subsystem and the decision nodes in the decision chain ( corresponding) relationship.

Fig. 5 is an information interaction diagram illustrating a selection decision node according to an embodiment of the present disclosure. In FIG. 5 , the electronic spectrum management device 100 includes the SAS and the CxM. For simplicity, two coexisting nodes (CBSD-1 and CBSD-2) existing in the CxG corresponding to the CxM are taken as an example for illustration.

In S51, CxM receives registration requests from CBSD-1 and CBSD-2 respectively, and in the registration requests, CBSD-1 and CBSD-2, for example, report to CxM that they support the blockchain spectrum trading function. It should be noted that among the electronic devices in the coexistence group, there may be electronic devices that do not support the blockchain spectrum trading function. Such electronic devices cannot conduct spectrum transactions with electronic devices that support the blockchain spectrum trading function through the blockchain. . In the following, unless otherwise specified, electronic devices refer to electronic devices that support the blockchain spectrum trading function.

In S52, the CxM sends registration responses to CBSD-1 and CBSD-2 respectively.

In S53, in each synchronization period, periodical coordination between SASs and CxMs (for example, synchronization information).

In S54, the CxM determines the number of decision nodes.

In S55, the CxM selects a decision node based on the interference overlap graph.

In S56, if the selected decision nodes include CBSD-1 and CBSD-2, the CxM sends an election request to CBSD-1 and CBSD-2 respectively about whether they can become decision nodes.

In S57 , the CxM receives from CBSD-1 an election rejection for refusing to become a decision node, and receives an election response for agreeing to become a decision node from CBSD-2.

In S59, the CxM receives an election success confirmation from CBSD-2, thereby confirming that CBSD-2 becomes the decision node.

In S60, the CxM sends the interference overlap map to CBSD-2, so that CBSD-2 can verify the spectrum transaction based on the interference overlap map.

FIG. 6 is a diagram illustrating an example of a cross-chain transaction performed by a decision chain according to an embodiment of the present disclosure.

As shown in FIG. 6 , the block information includes, for example, cross-chain transaction-1, cross-chain transaction-2, and cross-chain transaction-3. Among them, in the cross-chain transaction list of each cross-chain transaction, it includes the transaction ID, the ID of the spectrum acquisition electronic device (also called the buyer), the ID of the spectrum providing electronic device (also called the seller), and the buyer's emission Power and other information.

Fig. 7 is a diagram illustrating information interaction in a cross-chain transaction according to an embodiment of the present disclosure. In Figure 7, the coexistence node CBSD-1 in the coexistence chain CxG-1 corresponding to CxM-1 is a spectrum acquisition electronic device (also called a buyer or a buyer node), and the coexistence chain CxG-2 corresponding to CxM-2 The co-existence node CBSD-2 in CBSD-2 provides electronic equipment for spectrum (may also be referred to as seller or seller node).

In S701, CxM-1 receives a spectrum query request sent by CBSD-1.

In S702, CxM-1 looks for sellers available for spectrum trading.

In S703, CxM-1 replies a spectrum query response to CBSD-1.

In S704, CBSD-1 decides whether to apply for a cross-chain transaction according to the information in the spectrum query response. Assuming that CBSD-1 needs to apply for a cross-chain transaction, CBSD-1 sends an application for spectrum transaction to CxM-1.

In S705, CxM-1 determines whether the application for spectrum trading meets predetermined requirements based on the information of CBSD-1.

In S706, only when it is determined that the application meets the predetermined requirements, the CxM-1 sends transaction-related information to the SAS.

In S707, the SAS preprocesses the spectrum transaction to protect the main system from damage caused by the interference caused by the spectrum transaction (in other words, verify the interference of the main system).

In S708, after performing the above preprocessing on the spectrum transaction, the SAS sends the verification result of the main system interference to the CxM-1. If the verification result shows that the main system will not be damaged by the interference caused by spectrum trading, the subsequent processing can be continued, and if the verification result shows that the main system will be damaged by the interference caused by spectrum trading, the spectrum will not be carried out trade.

In the case where the verification result shows that the main system will not be damaged by interference caused by spectrum trading, in S709, CxM-1, for example, sends transaction information such as buyer and seller information and an application related to spectrum trading to CxG-1 The corresponding decision node, the decision node corresponding to CxG-1 sends the information to the decision node corresponding to CxG-2.

In S710, the decision node corresponding to CxG-2 sends the application related to spectrum trading to CBSD-2.

In S711, CBSD-2 sends a transaction response to the decision node corresponding to CxG-2.

In the case that the transaction response indicates that CBSD-2 agrees to conduct spectrum transactions, the decision node corresponding to CxG-2 sends the transaction response to the decision node corresponding to CxG-1.

In S712, the decision node corresponding to CxG-1 sends the transaction response to CxM-1 and CBSD-1.

In S713, CxM-1 sends the transaction information to the decision node corresponding to CxG-1, and the decision node corresponding to CxG-1 sends the transaction information to other decision nodes in the decision chain.

In S714, the decision nodes in the decision chain verify and process the spectrum transaction.

In S715, the decision node corresponding to CxG-1 sends the transaction result to CxM-1 and CBSD-1.

In S716, CxM-1 receives the spectrum authorization request sent by CBSD-1.

In S717, CxM-1 sends a spectrum authorization response to CBSD-1 and allocates the traded spectrum to CBSD-1. CBSD-1 pays transaction fees to CBSD-2 via CxM2, and pays transaction incentives to decision nodes (for example, handling fees for decision node processing).

An example of an implementation manner of a spectrum management system according to an embodiment of the present disclosure is described below.

Assume that in a wireless communication scenario, there are a primary system and a secondary system. Only the spectrum access system has the interference protection point information of the primary system, and the spectrum access system protects the communication quality of the primary system. A total of N coexistence nodes managed by different coexistence managers in the secondary system are randomly distributed in the area, and the coexistence managers are responsible for their spectrum resource allocation and coexistence, and the coexistence managers can interact with interference information in the secondary system. The coexistence nodes managed by each coexistence manager are connected to the same blockchain, and each coexistence node has set its own transmission parameters, and has been allocated initial spectrum resources. Spectrum transactions are possible, which can include on-chain transactions within the same blockchain and cross-chain transactions between different blockchains. The coexistence manager exchanges the interference information once every synchronization cycle, and selects the decision nodes to construct the decision chain according to the interference relationship. The process of a cross-chain transaction is as follows, for example: the coexistence node 1 (buyer node) on the coexistence chain 1 needs additional spectrum, and needs to apply for a transaction from other coexistence nodes. Coexistence node 1 first applies to its affiliated coexistence manager 1 to inquire about spectrum information available for trading (including potential seller nodes and frequency bands), assuming that coexistence manager 1 returns the information of coexistence node 2 on the coexistence chain 2 to coexistence node 1 . The coexistence node 1 initiates a transaction application to the coexistence manager 1. For example, the coexistence manager 1 can first verify part of the content of the transaction, such as verifying the registration information of the buyer node, the account balance of the buyer node, historical transaction reputation value, and at least Is one of the violations etc. After the verification is passed, the coexistence manager 1 sends the transaction information to the spectrum access system for the spectrum access system to verify the interference of the main system protection point. The transaction application that passes the interference verification will be broadcast by the coexistence manager 1 to the decision node in the coexistence chain 1 corresponding to the coexistence manager 1, and the decision node will send the transaction application to the coexistence node 2 through the decision node corresponding to the coexistence node 2, If the coexistence node 2 agrees to the transaction application, the transaction will be stored in the transaction pool of the decision node. The decision-making chain verifies whether each transaction will cause interference to relevant nodes. If the interference to all relevant nodes is lower than the interference threshold, the transaction verification is passed. After the spectrum transaction is completed, the coexistence manager 1 authorizes the spectrum resource applied by the coexistence node 1 to the coexistence node 1 for use.

As shown in Figure 8, the simulation parameters are set based on the CBRS standard. The size of the simulation scene is 2km×2km, and there are 2 coexisting CxMs in the scene, and each CxM manages 20 to 100 coexisting nodes (CBSD). The transaction interference threshold is set to -96dBm, the operating frequency is 3.6GHz, the path loss coefficient is set to 2.4, and the transmit power of the coexisting nodes is set to 20dBm. In the following throughput simulation, 70 coexisting nodes and 210-2800 user equipments can be set, and the throughput requirement (traffic requirement) of each user equipment is set to 8-10 Mbps. The coordinates of the main system protection point are set to (3000m, 3000m), and the interference threshold of the main system protection point is -96dBm.

FIG. 12 is a graph showing an example of the comparison of the impact of the cross-chain transaction mechanism and other transaction mechanisms on the cumulative throughput performance of the network according to an embodiment of the present disclosure. Considering the limitation of the current blockchain transaction throughput in the simulation, it is assumed that each parallel blockchain adopts the setting of Ethereum, that is, the transaction throughput is approximately 20 transactions per second, and there are a certain number of transactions in the blockchain network. Transactions need to be processed. A block generation cycle and a transaction processing time of about 15 seconds are compared, and the cumulative throughput of the network brought about by different mechanisms changes with the number of users. Other trading mechanisms in Figure 12 include: cross-chain spectrum trading by CxM interaction (that is, spectrum trading between different blockchains via CxM), the use of a single blockchain (single chain) mechanism, and no spectrum trading Mechanisms. It can be seen that within a certain period of time, the cross-chain transaction mechanism according to the embodiments of the present disclosure can significantly improve the cumulative network throughput brought by transactions compared with other mechanisms.

Other trading mechanisms in Figure 13 include: cross-chain spectrum trading by CxM interaction (that is, spectrum trading between different blockchains via CxM) and the mechanism of using a single blockchain (single chain). Figure 13 counts the increase in the number of transactions brought about by the cross-chain transaction mechanism according to the embodiment of the present disclosure relative to the single-chain mechanism within 15s, and also counts the cross-chain transaction mechanism according to the embodiment of the present disclosure relative to the cross-chain transaction by CxM interaction The increase in the number of transactions brought about by the spectrum trading mechanism. It can be seen that the cross-chain transaction mechanism according to the embodiments of the present disclosure can complete more effective transactions within a certain time limit, that is, the overall transaction throughput of multiple blockchains has been improved.

FIG. 14 is a diagram illustrating an example of accumulated interference of a main system protection point according to an embodiment of the present disclosure. In the simulation, after each spectrum transaction is executed, the interference caused by the change of the spectrum usage of the buyer node to the main system protection point is considered. If the interference caused by a spectrum transaction exceeds the first predetermined threshold, the spectrum transaction will be invalid. The simulation results show how the cumulative interference of the main system protection point varies with the number of nodes, and specifically show the cumulative interference of the main system protection point after a round of cross-chain transactions when the above-mentioned preprocessing according to the embodiment of the present disclosure is adopted, and without The cumulative interference of the main system protection point during the above preprocessing mechanism (the unit of cumulative interference is dBm/10MHz). It can be seen that when the above-mentioned preprocessing according to the embodiment of the present disclosure is adopted, the interference effect of the cross-chain transaction on the main system can be reduced.

FIG. 15 is a diagram showing an example of comparison of selfish behaviors of decision nodes in different decision chain construction methods. When the decision-making chain node verifies the spectrum transaction, the buyer node of the spectrum transaction will interfere with it, and the decision-making chain node may deny the transaction with a certain probability, that is, selfish behavior. In the simulation, the method of constructing a decision chain using the interference overlap graph according to the embodiment of the present disclosure, the method of constructing the decision chain using the interference overlap graph and the transaction reputation value according to the embodiment of the present disclosure, and the method of constructing the decision chain based on PoW are compared. The average number of selfish actions of decision nodes in the decision chain. The simulation results show that the method of constructing a decision chain using the interference overlap graph according to the embodiment of the present disclosure and the method of constructing the decision chain using the interference overlap graph and the transaction reputation value according to the embodiment of the present disclosure can reduce the influence of selfish behavior, and when considering reputation The improvement in the performance of reducing selfish behavior is more significant when the value is .

In case of damage caused, the spectrum transaction is verified, wherein the spectrum acquisition electronic device in the subsystem in the spectrum management system sends an application for the spectrum transaction to the spectrum management electronic device.

Wherein, the verification unit 1601 may be implemented by one or more processing circuits, and the processing circuits may be implemented as a chip, for example.

The decision electronic device 1600 may be a base station, and the base station may be, for example, an eNB or a gNB. Specifically, the decision-making electronic device 1600 may be set at the side of the base station or be communicably connected to the base station, for example. Here, it should also be pointed out that the decision-making electronic device 1600 can be implemented at the chip level, or can also be implemented at the device level. For example, the decision electronics 1600 may function as a base station itself, and may also include external devices such as memory, transceivers (not shown), and the like. The memory can be used to store programs and related data information that the base station needs to execute to implement various functions.

As an example, the decision-making electronic device 1600 is selected based on the reputation value of the candidate decision-making electronic device corresponding to the coexistence group to which it belongs. Those skilled in the art can also think of other ways to select the decision-making electronic device from the candidate decision-making electronic devices corresponding to the coexistence group, which will not be repeated here.

As an example, the total number of candidate decision-making electronic devices selected from all coexistence groups included in the secondary system is a third quantity, and the total number of decision-making electronic devices 1600 selected from all coexistence groups is a fourth quantity, wherein, The fourth number of decision-making electronic devices 1600 constitutes a decision-making group, and the decision-making electronic devices 1600 in the decision-making group can communicate in real time, and when the third number is less than the predetermined minimum number of decision-making electronic devices, the fourth number is set to 0 , when the third number is greater than or equal to the predetermined minimum number of decision-making electronic devices and less than the predetermined maximum number of decision-making electronic devices, calculating the fourth number based on the third number, and in the case where the third number is greater than or equal to the predetermined maximum number of decision-making electronic devices Next, the fourth number is set as the predetermined maximum number of decision-making electronic devices.
