It should also be noted that like numerals and letters in the figures indicate like items, and thus once an item is defined in one figure, it need not be discussed for subsequent figures.

In the present disclosure, the terms "first", "second", etc. are only used to distinguish elements or steps, and are not intended to indicate chronological order, preference, or importance.

In the vast rural areas or tourist attractions, the flow of people is usually unevenly distributed and the area spreads widely. It is in line with the laws of the market economy to use a low-cost and highly flexible network coverage scheme to achieve communication in this area. However, the currently commonly used 4G or 5G has scale effects and price advantages in ultra-high-density aggregation areas, and in the above-mentioned wide area scenarios, especially such areas with sparsely populated areas and random aggregation characteristics , the cost is high and the location of the base station cannot be changed flexibly, resulting in poor communication service effect.

For communication scenarios in wide areas, especially the communication of random gathering points of multiple people in a wide area, a relay network can be built to use multiple relay paths to provide services for users in the scenario. The path in the relay network is usually composed of multiple APs (access points) or wireless connections of appropriate devices. The AP at one end is connected to the fixed network, and the AP at the other end can access and serve user terminal equipment. In particular, from the access point of the fixed network, or the large base station in the network, through multiple APs, data can be exchanged wirelessly with the communication equipment of the crowd in the remote place in the form of relay, so that the relay path can be used to achieve wide bandwidth. Communication in open area communication scenarios.

However, in the current communication resource management (such as spectrum management), the communication resources are usually allocated in advance for the equipment in the wireless communication system, such as the relay AP, and then for the relay path formed by the relay AP, so that the During the communication, the relay path will use the pre-allocated communication resources to provide services for the user, and the allocated resources are basically kept constant during the communication. However, in the process of use, it usually occurs that the authorized communication resources of some relay paths or APs cannot meet their usage requirements, while the authorized communication resources of other relay paths are in an idle state. The system performance is adversely affected and communication resources are wasted. This is especially true when communication resources are limited.

In order to alleviate the shortage of communication resources, the 5G network can carry out refined management of communication resources, realize the sharing of communication resources in different frequency bands, exchange and utilize communication resources between different base stations/devices, and various networks (such as 5G network spectrum). , IoT vertical industry spectrum, WIFI free spectrum) to dynamically share communication resources. For the scenario of using a relay network composed of relay paths for communication, if some relay paths do not need to communicate in certain periods or do not require so many allocated spectrum resources for communication, a good idea is to Allocate idle spectrum resources to other relay paths that urgently need spectrum resources, so that the spectrum efficiency of the entire system is greatly improved.

In addition, the sharing and allocation of communication resources should consider information security in addition to meeting the needs of all parties. As an emerging technology, blockchain is essentially a digital distributed ledger technology with the characteristics of decentralization, trustlessness, immutability, encryption security and openness. Therefore, blockchain technology can be used to manage the shared allocation and use of various spectrums by various networks and various terminals, and can better achieve high security and information protection.

In view of this, in the present disclosure, a dynamic communication resource allocation/sharing scheme for relay paths is proposed, in which paths are used as basic transaction objects, so that different paths can trade redundant/idle spectrum resources, thereby improving the utilization of spectrum resources. overall utilization efficiency. In particular, the relay path can dynamically request or provide communication resources to the appropriate relay path according to its own communication requirements and the degree of possible interference with adjacent paths, so that the communication resources between the relay paths can be realized. Effective dynamic reallocation makes the allocation and use of resources more suitable for the application requirements of system equipment, improves the utilization efficiency of resources, and improves the communication performance.

Further, in the present disclosure, a dynamic communication resource allocation/sharing scheme based on the relay path of the blockchain technology is also proposed. In particular, the exchange of available spectrum resources can be realized between different paths through blockchain technology. Blockchain can help 5G solve problems such as user privacy information security, online transaction trust establishment, and virtual intellectual property protection, so as to optimize resource utilization. At the same time of efficiency, it improves the security of information transmission and realizes the improvement of communication services. In this disclosure, the term "blockchain technology" includes, but is not limited to, technologies such as distributed storage, peer-to-peer networks, consensus mechanisms, and encryption algorithms. A detailed description will not be given here.

In the present disclosure, in particular, the dynamic allocation/sharing of resources in a wireless communication system can be realized by means of resource transaction by means of blockchain technology. In particular, relay paths that can request (also referred to as procuring) additional resources to communicate/provide services and relay paths that can allocate/offer/share (referred to as selling) their own spare resources as both parties to a resource transaction , the use of blockchain technology to realize the purchase and sale of resources, and transactions can also be confirmed by appropriate equipment. Typically, in the wireless communication system of the present disclosure for resource sharing in a resource transaction manner, at least a resource purchase end, a resource seller end, and a transaction accounting end of communication resources can be divided based on the roles of each party in the transaction. In this disclosure, a "resource buyer" of a wireless communication system has the full breadth of its usual meaning, generally indicating a relay path in the communication system that requires additional communication resources to communicate and/or provide services, eg, corresponding to the path The "resource seller" of a wireless communication system has the full breadth of its usual meaning, or a device participating in a transaction on behalf of that path, generally indicating a relay in the communication system that can provide additional idle communication resources for use by other relay paths A path, such as a device corresponding to the path or participating in a transaction on behalf of the path, the "transaction billing end" of a wireless communication system has the full breadth of its usual meaning, usually indicating the relationship between the resource buying end and the resource selling end in the communication system. A device that summarizes the transactions concluded between them, sends them to the parties in the communication system for authentication, and finally confirms them. It should be pointed out that the aforementioned resource buying end, resource selling end, transaction and account end, etc. are mainly divided/named according to their respective roles/functions in the resource transaction process. In an actual wireless communication system, their corresponding Paths and/or devices may be separated from each other, and their corresponding paths and/or devices may also overlap with each other. For example, a path/device in a wireless communication system may be either a resource buyer or a resource seller, or a transaction accounting end.

As an example, resource transactions between relay paths may be performed as follows: Paths that request/purchase resources (also known as buyer paths) use bidding to provide/distribute/sell resources to paths (also known as sellers) Path) to apply for resource transaction, the seller path selects the buyer path to be traded according to the rules, and all transactions are summarized by the accounting device/node in the system, and then the unauthenticated blocks are packaged and sent to all parties in the system for authentication. If a certain transaction is finally confirmed as a legitimate transaction, it will be recorded in the newly generated block by the accounting device/node and notified to all parties in the system. In the context of the present disclosure, the execution of resource allocation/transaction between relay paths may be performed by devices corresponding to the relay paths, for example, a device corresponding to each path, or a common device corresponding to multiple paths .

The communication resources in the wireless communication system mentioned in the present disclosure may refer to various resources that can be used by the relay paths in the wireless communication system, especially the devices included in the relay paths, in order to communicate and/or provide services. resources, such as any of physical resources, channel resources, time-frequency resources, etc., and these resources can take various forms and be used by devices in the relay path in the wireless communication system in various appropriate ways, It will not be described in detail here. As an example, the system scenario allows the use of private network spectrum resources or non-certified spectrum resources, such as specified available spectrum resources in CBRS or white spectrum resources in TVWS, which can be dynamically allocated between paths.

According to the embodiments of the present disclosure, when multiple paths in the communication system perform dynamic allocation/transaction of communication resources based on the blockchain technology, various appropriate communication methods can be used to transmit information between paths to realize transaction information and Control the interaction of information. It should be noted that, in the context of the present disclosure, the interaction of resource allocation/transaction-related information between relay paths is substantially equivalent to the information interaction between respectively corresponding devices of the relay paths. As an example, each path may have its corresponding information transceiving device for transceiving information with devices of other paths. In the present disclosure, information exchange between paths can be implemented in an appropriate manner. According to an embodiment of the present disclosure, these information exchanges can be accomplished through a public network (eg WiFi or 5G). For example, all devices access a common network, such as WiFi or a cellular network, to complete the task of information exchange. According to another embodiment of the present disclosure, the information interaction can also be implemented by the method for an ad hoc network provided by the present disclosure. For example, a frequency band is selected from the available spectrum resources as a common channel, and then an Ad-hoc network of devices is constructed, and an appropriate routing protocol is used to complete the transmission and interaction of resource allocation/transaction information. For example, table-driven DSDV, CGSR, WRP protocols can be used, and reactive routing DSR, AODV, and TOAR can also be used. The determination of the information interaction mode may be notified by the device of the path by broadcasting, or each path may be notified in advance by other control devices. It will not be described in detail here.

Exemplary implementations of the embodiments of the present disclosure will be described below by taking a relay network composed of relay paths including a plurality of APs as an example. As an example, each path consists of several APs, including at least an AP connected to a fixed network or any suitable functional network, a terminating AP that is the ultimate serving AP of the path, and possibly specific specific APs located in between. The intermediate AP can transmit data from the fixed network access AP to the terminating AP. Multiple relay paths are completely independent, that is, no two paths have a common AP node. The AP node here refers to a node other than the node connected to the fixed network. That is to say, multiple relay paths in the relay network can access the fixed network through the same AP node, that is, have the same AP node accessing the fixed network, or can have their own AP nodes accessing the fixed network, The other APs in each path are independent of each other.

FIG. 1 illustrates a communication scenario in accordance with the present disclosure, which includes multiple communication paths. AP 0 is a node accessing the fixed network, and multiple paths can be derived from AP 0. For example, path 1 includes {AP 0, AP 1, AP 2}, and path 2 includes {AP 0, AP 3}. Each path has a final serving AP called a terminating AP, such as AP 2 in path 1 and AP 3 in path 2 in Figure 1. Usually the frequency of the relay AP is relatively low, which is suitable for long-distance transmission. When transmitting to the crowd gathering point, the radio frequency conversion AP (sAP1, sAP2, sAP3, and sAP4 in Figure 1) can be used, which converts the frequency of the radio frequency signal from a higher frequency. The low frequency band is raised to the high frequency band (for example, from 700MHz to 2.4GHz), which is conducive to distributing services to more users, such as providing communication services for user terminal equipment. In the present disclosure, a terminal device may refer to a terminal device that is part of a wireless communication system or a radio system to communicate, especially a customer premises equipment (UE) of a wireless communication system, such as a vehicle or a vehicle communication device in V2X, Mobile devices in cell communication, robots in similar application scenarios, or components thereof.

Communication resource allocation/sharing can be performed between different paths, such as spectrum resource allocation/sharing, so as to maximally satisfy the communication service of the terminal AP of the path to the terminal device. Since each path is formed by the relay propagation of multiple APs, if the respective APs of the two paths interfere with each other, it is considered that the two paths may have interference, and then the spectrum can be allocated based on the degree of interference.

According to an embodiment of the present disclosure, whether there is mutual interference between paths may be determined according to the relationship between the coverage areas of the paths. In particular, considering the coverage of the radio frequency signals of the paths, if the coverage of different paths has an intersection, it is considered that these paths may have interference, and then there is the possibility of spectrum trading. Also, AP nodes accessing the fixed network of the paths are not considered when determining the interference between the paths. In particular, AP 0 can sometimes support sending data to AP1 and AP3 simultaneously using the same frequency band (for example, by using spatial division multiple access), so AP0 does not need to be considered as an interference factor between the two paths.

Fig. 2 schematically shows a schematic diagram of different relay paths, wherein the coverage of each node in the relay path is schematically shown.

The coverage of a path can be defined as the union of the coverage of other APs in the path except the AP connected to the fixed network. For example, path 1 in FIG. 2 is {AP0, AP1, AP2}, where AP0 is connected to the fixed network and AP2 is the terminating AP, so the coverage of path 1 is the union of the coverages of AP1 and AP2. Assuming that the coverage of all APs is a circle with a radius of Rc, the coverage of a path is the union of the coverage of the circles of all APs on the path. Of course, the coverage areas of different APs may also have different sizes, for example, circle domains with different radii.

There may be overlap/crossover between the coverage areas of the relay paths. In particular, the overlap/intersection between the coverage areas of the relay paths can be particularly manifested as the overlap/intersection between the coverage areas of the APs included in the relay paths, such as the overlap/intersection between the dotted circles in FIG. 2 . shown. That is, if the coverage of one AP included in one relay path overlaps/crosses the coverage of any AP included in an adjacent relay path, the two relay paths can be considered to overlap. For example, the coverage areas of AP1 and AP2 in path 1 in FIG. 2 overlap with the coverage areas of AP4 and AP5 in path 2, and then the coverage areas of path 1 and path 2 can be considered to overlap. Preferably, when an AP included in one relay path is located in the coverage area of any AP included in an adjacent relay path, it can be considered that the two relay paths overlap/cross, and their coverage areas overlap. For example, AP1 in Path 1 in FIG. 2 is located in the coverage area of AP4 in Path 2, and/or AP4 in Path 2 is located in the coverage area of AP1 in Path 1, that is,

paths

1 and 2 have mutual APs located in Therefore, it can be considered that the coverage areas of Path 1 and Path 2 overlap. As a result, interference may occur between

paths

1 and 2, and there is a possibility of spectrum trading.

According to the embodiments of the present disclosure, regarding the dynamic allocation/transaction of spectrum resources between relay paths in the relay network, the path will determine the amount of spectrum that the path undertakes according to the bandwidth requirements of the terminating AP to provide services and the existing spectrum resources. Role (buyer path or seller path). If more spectrum resources are needed, the path is the buyer's path; if there are excess spectrum resources idle, the path is the seller's path. As another example, the role assumed by the path may also be determined according to the communication requirements/resource usage of the APs included in the path.

According to an embodiment of the present disclosure, the buyer path is a seller path that is suitable for transaction with which is determined in consideration of communication interference. In particular, buyer paths may purchase spectrum from adjacent relay paths with overlapping/intersecting coverage areas, because paths that use spectrum resources in the intersecting coverage areas will interfere with the communications of surrounding paths, so paths that cross coverage areas will The resource redistribution between adjacent paths can effectively balance the resource allocation between adjacent paths, thereby reducing the impact of resource allocation and utilization on the system. In this way, adjacent relay paths with idle communication resources that overlap/cross the coverage of the buyer's path can serve as the seller's path.

According to the embodiment of the present disclosure, in the transaction system, the buyer relay path for purchasing resources makes an offer to the seller path capable of selling the resource, and the seller path can choose to accept the quotation of the appropriate path, so that the relationship between the seller path and the seller path can be selected. Transactions for dynamic resource allocation and sharing. It should be pointed out that the resource allocation/transaction between paths can be performed by appropriate equipment, and usually, for convenience, the AP connected to the fixed network that can select the path assumes the role of executing the path resource allocation/transaction. Of course, path resource allocation and sharing can also be performed by other devices, such as other APs included in the path (for example, APs with sufficient processing power), the public AP responsible for all paths connected to the fixed network, the or other suitable device in the system, etc.

The following will describe the flow of an inter-path spectrum transaction scheme according to an embodiment of the present disclosure with reference to FIG. 3 . FIG. 3 schematically shows a signaling interaction diagram of a resource transaction according to the present disclosure. The signaling interaction between the path and the transaction confirmation device, where the transaction confirmation device can play the role of the accounting node in the blockchain technology in some operations, which can be equivalent to the selected node with accounting rights, It summarizes all transactions, then packs unauthenticated blocks for authentication, and then combines the authentication results obtained by all parties to determine legal transactions. It should be noted that, although not shown, the relevant information of the paths in the relay network, such as the resources to which the paths are allocated, resource requirements, etc., may be determined or informed to the servers in the network before the interactive execution of the flow instructions of FIG. Determine the paths that are both sides of the transaction before resource allocation/transaction. This operation may be performed by the control device of each path, the device included in the network, the common control device of the network, other suitable devices in the network, or the like. Transaction confirmation devices can also be informed/broadcasted to all paths in the system prior to resource allocation/transaction.

In the implementation of this solution, the buyer's path and the seller's path can be determined according to the needs of the terminating AP and the spectrum resources it possesses, as described above. Furthermore, it should be noted that the buyer's path and the seller's path may not be fixed, but dynamically adjust as the transaction progresses. That is to say, the path will adjust its own purchase or sale status of resources according to the number of terminals that need to be served and its own resource status. In particular, after the buyer path acquires additional communication resources through a transaction, if in the subsequent communication process, the number of terminals served by the terminating AP decreases and its own resources become idle, the buyer path may ask for resources from resources The party becomes the resource seller. On the contrary, after the seller path uses its idle communication resources by other paths through transactions, if in the subsequent communication process, the number of terminals served by the terminating AP increases and its own resources are insufficient, the seller path may change from The resource seller becomes the resource buyer to request additional communication resources.

After the buyer and seller paths are determined, the buyer path can select a path available for trading to make an offer for the required communication resources according to its own needs and the learned conditions of each path. In particular, the buyer path takes into account the degree of interference between it and adjacent paths, such as overlapping/intersecting conditions of coverage, etc., to select the path available for trading.

The buyer path, eg, via its responsible equipment, can then provide an offer to the selected seller path for the required communication resources. The information related to the offer may include identification information of the buyer's route, the quantity of resources required by the buyer's route, the bid of the buyer's route for the resource, and the like is transmitted to the seller's route. The information may be represented in any suitable format, for example, the information may be a data packet, the content of which may occupy corresponding fields, and may be transmitted in any suitable manner, which will not be described in detail here. In addition, the bid can refer to the cost/price that the buyer path is willing to pay for seeking/obtaining the resource, and can indicate any content accepted by both the buyer path and the seller path, such as physical entities, virtual objects, etc., for example, can communicate with physical resources related. This cost/cost can be expressed in any suitable way, as long as it is acceptable to both the buyer's path and the seller's path, as described further below.

After receiving the quotation from the buyer's path, the seller's path selects a certain buyer's path as a transaction object according to the rules according to the received quotation of the buyer's path. As an example, the seller path selects transaction objects from multiple buyer paths according to specific rules, and determines the spectrum selling price. The seller path that the specific rule may refer to selects an appropriate buyer path according to various criteria, for example, according to the level of bids, the degree of correlation between the buyer and seller paths, and the like.

After determining the buyer's route intended to conduct the transaction, the seller's route, eg via its responsible device, may notify the transaction control device of the proposed transaction. Specifically, the responsible device of the seller's path sends the identification information of the seller's path, the identification information of the selected buyer's path, bidding information and other information to the transaction confirmation device, and the transaction confirmation device can be used as an accounting node. According to the present disclosure, the billing node may also be other suitable devices, such as APs included in the path (even APs in the seller or buyer path), other suitable APs in the system, and so on. Accounting nodes may be selected from APs in a communication scenario in various suitable ways, in particular may be based on the network for the interaction of route transaction related information. According to one embodiment, if a public network such as WiFi or a cellular network is used for information exchange, each path can use a traditional PoW or PoS mechanism to compete for accounting rights, which is well known in blockchain technology and will not be described in detail here. Thus, the corresponding devices competing for the path to the billing right can be responsible for billing. After the accounting node in the communication scenario is determined, it can notify each path in the communication scenario in an appropriate way, for example, it can be determined when the communication network is constructed and broadcasted to notify each path in the communication network, or during operation. It is informed in other ways and will not be described in detail here.

The transaction confirmation device aggregates all proposed transactions and sends them to the appropriate relay path for authentication. As an example, the relevant information for all proposed transactions may be generated as unauthenticated blocks to be sent to the buyer and seller routes for authentication. It should be noted that, although not shown, the transaction confirmation device may also send unauthenticated blocks to other suitable relay paths in the network. As another example, unauthenticated blocks may also be sent to paths that are related to the resources involved in the transaction, but are not involved in the transaction. As yet another example, even unauthenticated blocks may be sent to all paths in the relay network for authentication.

Each path that receives an unauthenticated block can authenticate the proposed transaction and feed back the transaction authentication status to the transaction confirmation device. As an example, those participating in the authentication path will classify all transactions, and then authenticate transactions that are related to or affect themselves. Then feedback the authentication result.

Then, the transaction confirmation device collects the transaction authentication information from each path, finally confirms each transaction in the block, and writes the legal transaction into a new block. The legal transaction may refer to an approved/licensed resource transaction, and the determination of the legal transaction may be performed by various determination methods in the blockchain technology, which will not be described in detail here. After this, the transaction controller station distributes the verified blocks to the various paths. This resource transaction ends. The blocks in the transaction confirmation process may take various suitable forms, such as the block form shown in FIG. 4 .

As can be seen from the above, the present disclosure proposes a path spectrum transaction method based on blockchain technology that supports relay network communication, which can meet the needs of rapidly building a flexible relay network under wide coverage, and realize multiple relay paths under the network. The exchange of communication resources between them, such as the exchange of spectrum resources. Among them, based on the blockchain technology, different paths can realize spectrum transactions through transaction confirmation equipment as an intermediary, so that the spectrum resources of each path in the relay network can be flexibly adjusted, and the number of users and service quality of the entire system can be effectively improved. demand, and further improve security with the help of blockchain technology.

Embodiments according to the present disclosure will be described below with reference to the accompanying drawings. In particular, the parties involved in resource allocation/transaction in a wireless communication system will be described separately, including in particular electronic devices and methods related to resource purchase, resource sale, and transaction confirmation. Among them, electronic equipment related to resource purchase, electronic equipment related to resource sales, and electronic equipment related to transaction confirmation can communicate through a public network, or can communicate through an ad hoc network.

An exemplary electronic device for requesting a path for acquiring wireless communication resources, ie, a resource buyer path, of the wireless communication system according to an embodiment of the present disclosure will be described below. 5 is a block diagram schematically illustrating an electronic device for requesting a relay path for wireless communication resources of a wireless communication system according to an embodiment of the present disclosure. The electronic device 500 includes a processing circuit 502 configured to: determine a certain number of adjacent relay paths that may have communication interference with the relay path for requesting redundant wireless communication resources, the certain number being dependent on the medium. communication requirements of a relay path; and requesting redundant wireless communication resources from the adjacent relay path based on a spatial interference coefficient between the relay path and each of the specified number of adjacent relay paths.

In particular, in the context of the present disclosure, the relay path for requesting communication resources may be the resource buying side, which may be referred to as the buyer path, and the relay path for the requested communication resources may be the resource selling side, which may be referred to as the seller path . It should be pointed out that the electronic device may correspond to an electronic device in the wireless communication system that is responsible for the resource purchase operation of the buyer path, which may be a specific device corresponding to the buyer path, such as a device that accesses a fixed network (such as a fixed network) of the path. Access AP), the specific device included in the path (such as a relay AP), or even other suitable devices in the system, such as the public fixed network access device for all paths, other control devices in the fixed network, etc., or are electronic devices used in conjunction with these devices.

According to the embodiment of the present disclosure, the wireless communication resource to be purchased depends on the communication requirement of the terminal device served by the relay path, for example, the communication requirement within the communication coverage of the terminating AP of the relay path. In particular, the quantity of wireless communication resources to be purchased on the relay path depends on the number of users (or terminals) perceived by the terminating AP of the path, and may also depend on the users (or terminals) served by each unit of communication resources. quantity. For example, the perceived number of users may be, for example, the number of users within the communication coverage of the terminating AP. As an example, the number of users can be periodically detected and updated during the communication process. For example, the terminating AP can actively detect the number of users, or automatically update the number of terminals when the user accesses the electronic device, and notify the electronic device responsible for the wireless communication resource transaction. equipment. As an example, the coverage of a terminating AP may be informed by the system before the communication begins, and typically remains unchanged during the communication.

As an example, assuming that the communication resources are in units of basic bandwidth units, and the number of terminals that can be served by a basic bandwidth unit is determined, then by determining the number of terminals perceived by the terminating AP, such as the number of terminals within the coverage area of the AP, The required number of bandwidth units can be known, thereby judging whether the communication resources possessed by the current AP meet the requirements.

As an example, generally, the number of users that can be served by a basic bandwidth unit W is assumed to be Nc, the number of users perceived by the terminating AP of the current path is Na, and the spectrum resources owned by this path are x W. Assuming that the number of units of spectral resources that are redundant in the current path is r, it can be expressed by Equation (1).

If r is greater than 0, it means that the spectrum resources owned by the current path can be shared with other paths in addition to its own use, and the role of the current path can be the seller path. If r is less than 0, it means that the spectrum resources possessed by the current path cannot support user requirements, and additional spectrum resources need to be obtained from other paths, and the role of the current path can be the buyer path.

After determining that the current path needs to obtain additional spectrum resources from other paths, the electronic device will determine a path that may have communication interference with the current path.

According to the present disclosure, the relay paths in the system have their own communication coverage, for example, the relay devices included in the relay path, especially the devices other than the fixed network access device, may have their own communication coverage. union. According to the embodiments of the present disclosure, it is determined that there may be interference between the relay path and the adjacent relay path in the case where the communication coverage of the relay path and the communication coverage of the adjacent relay path overlap.

According to an embodiment, in the case where the communication coverage of the relay device included in the relay path overlaps with the communication coverage of the relay device included in the adjacent relay path, it is determined that the relay path is adjacent to the adjacent relay path. There may be interference between relay paths. As an example, as long as the coverage areas of any relay device in the buyer's path and any relay device in the seller's path overlap/cross, it can be considered that the communication coverage of the two paths overlaps, that is, there may be interference.

According to another embodiment, if one of any relay device included in the relay path and any relay device included in the adjacent relay path is located within the communication coverage of the other It is judged that there may be interference between the relay path and adjacent relay paths. As an example, as long as any relay in the buyer's path is within coverage of any relay in the seller's path, and/or any relay in the seller's path is in any relay in the buyer's path Within the coverage area, it can be considered that the communication coverage of the two paths overlaps, that is, interference may exist.

In accordance with the present disclosure, various suitable ways may be used to determine a path that interferes with the buyer's path, which may serve as a possible seller's path for a transaction. As an example, the interference condition may be determined based on the distance between other relay APs other than the fixed network access AP in the two paths. For example, the distance between two APs can be calculated based on their location coordinates, compared with the sum of the coverage radius of the two APs to determine whether the coverages of the two APs overlap, and if so, it can be confirmed There is interference. It should be noted that the location coordinates of the relay AP may be obtained in advance, for example, when the relay network is constructed. As shown in Figure 6A, the distance between APb and APs can be calculated as follows:

The location coordinates of APb are (x _b , y _b ), and its coverage is R _b , and the location coordinates of APs are (x _s , y _s ), and its coverage is R _s. From this, d _bs can be compared with R _b +R _s . For example, if d _bs <R _b +R _s , it is considered that there is overlap between the coverage areas of the two APs, and then it can be determined that the two paths to which the two APs belong respectively have interference. As another preferred example, when judging that d _bs is less than or equal to R _b or R _s , it may be considered that one of the two APs is located within the coverage of the other AP, and then two paths to which the two APs belong respectively may be determined. There is interference.

After determining the seller paths capable of conducting the transaction, bids are made for the required communication resources to pursue the transaction based on the degree of possible interference between the paths. According to embodiments of the present disclosure, the degree of possible interference may be based on spatial interference coefficients between paths.

According to an embodiment of the present disclosure, the spatial interference coefficient of a relay path and an adjacent relay path depends on an overlap condition between the communication coverage of the relay path and the communication coverage of the adjacent relay path. According to an embodiment of the present disclosure, the overlap condition depends on an overlap condition between a relay device included in the relay path and a relay device included in the adjacent relay path.

According to an embodiment, the overlapping condition between the relay devices included in the relay path and the relay devices included in the adjacent relay path can be represented by the distance between the relay devices, and the distance can be As calculated by equation (2) above, this is especially suitable for relays having the same coverage, eg circular coverage with the same radius.

According to another embodiment, the overlapping condition between the relay device included in the relay path and the relay device included in the adjacent relay path can be determined by the overlap/intersection of the coverage of the relay devices Area representation. The intersection area of the communication coverage can be determined in various ways, in particular, the intersection area can be determined based on the respective coverage sizes of the two APs (eg, can be characterized by a radius) and the distance between the two APs. According to the embodiment of the present disclosure, the intersection area S _c of the communication coverage of the electronic device and the adjacent electronic device is as follows:

Among them, d _bs is the distance between the electronic device and the adjacent electronic device; R _b is the radius of the communication coverage of the electronic device, and R _s is the radius of the communication coverage of the adjacent electronic device.

Figure 6B schematically illustrates the calculation of the overlap/intersection area between the coverage areas of two devices. Among them, AP _b represents the AP in the buyer's path, and AP _s represents the AP in the seller's path. It is assumed that the coverage area of the buyer and seller AP is a circular domain, and the radii are R _b and R _s in turn. According to the law of cosines, the radians of α and β in Fig. 6B are calculated respectively, as shown in formulas (3) and (4), and then the intersection area Sc of the coverage can be calculated as shown in formula (5).

According to an embodiment of the present disclosure, the spatial interference coefficient of a relay path and an adjacent relay path includes a spatial interference coefficient between each relay device included in the relay path and the adjacent relay path. In particular, spatial interference coefficients between the relay device and adjacent relay paths may be determined based on a set of interference coefficients between the relay device and each relay device included in the adjacent relay paths. For example, the spatial interference coefficient between the relay device and the adjacent relay paths is determined based on the distance or coverage intersection area between the relay device and each relay device included in the adjacent relay paths.

As an example, for the degree of possible interference between the paths, the spatial interference coefficient between the paths may be calculated. The interference coefficient may be in various suitable forms, in particular being determined based on the signal-to-interference-to-noise ratio of the path. The signal-to-interference-noise ratio of the path can be determined in various suitable ways. As an example, the interference of each AP of the current path by the adjacent paths, that is, the interference conditions of each AP in the adjacent paths, such as the signal-to-interference and noise ratio, can be calculated separately, and then based on the signal interference of the affected APs in the current path The sum of the noise ratios is used to determine the signal-to-interference noise ratio of the current path.

The calculation of the spatial interference coefficients, eg, the calculation method of the path 1 and path 2 interference coefficients, will be described below with reference to the coverage overlap in FIG. 2 . Assuming that path 1 is a buyer path, the set of APs except AP0 is β={b ₁ ,b ₂ ,...,b _u }, and path 2 is a seller path, and the set of APs except AP0 is Γ = {s ₁ ,s ₂ ,...,s _u }, calculate the interference between APs by calculating the overlap/overlap of coverage between APs in these two sets, and then obtain the interference between the two paths . Preferably, the interference between APs is calculated only when one AP in one path is within the coverage of one AP in the other path, and then the interference between the two paths is obtained.

Specifically, for any AP in the buyer's path, which corresponds to any b _z belonging to the set B, the coverage radius of Rc can be used to filter the subset Ωz from the set Γ to get the subset Ωz within the coverage range, if Ωz is the empty set , indicating that there is no s in the set Γ that has overlapping coverage with the AP, then b _z does not need to perform subsequent calculations. On the other hand, if Ωz is non-empty, that is, there is s in set Γ that has coverage overlap with this AP. For any s _w belonging to Ωz, the distance between b _z and s _w can be calculated as in equation (6):

in,

and

is the position coordinate of b _z ,

and

are the position coordinates of _sw , and these coordinate information can be obtained in advance, for example, it can be informed when the network is constructed.

From this, the interference of _sw to b _z can be calculated, as in formula (7):

where P _Tx is the communication signal transmit power of the AP in the vendor path indicated by _sw , G _Tx is the signal gain of the AP in the vendor path indicated by _sw , λ is the communication wavelength, and α is a constant, which can be empirically determined value.

Considering that the coverage of APs in the buyer's path and the seller's path is the same as _Rc , the interference of b _z to sw is the same as that of _sw to b _z . Thus, the interference problem only needs to be considered from the perspective of the buyer's path. For any element b _z belonging to the buyer path AP set B (required to have a corresponding non-empty Ωz seller AP subset), the SINR of the seller path can be obtained

Based on this, considering all APs in Ωz, the signal-to-interference-to-noise ratio at b _z can be obtained, which is the ratio of the received power to the sum of the reference noise and the interference of the seller's path to bz, as shown in Equation (8):

Wherein, P _Rx is the received power of the communication signal of the AP in the buyer path indicated by b _z , and N _o is the reference noise. Meanwhile, the normalized SNR=P _Rx /N ₀ is defined here, the ratio

It can be used to describe the interference loss, which can indicate the interference loss of an AP in the buyer's path interfered by the seller's path, and it can also indicate the interference coefficient of the AP in the buyer's path interfered by the seller's path, that is, the distance between the AP and the seller's path. interference factor. Then the interference loss of other APs in the buyer path can be similarly determined, so that the interference loss of the buyer path interfered by the seller path can be determined based on the mathematical statistics of the interference losses of all APs in the buyer path, such as mean, median, maximum value, etc. Wait. As an example, a key parameter in resource transactions can be defined: maximum interference loss

Thereby, bids may be made to the interference seller paths seeking to trade resources based on the interference loss, in particular the maximum interference loss.

It should be noted that in the above example, the interference loss is calculated by considering the distance between the relay devices, which is especially suitable for the case where the coverage radius of the relay devices is the same. As another example, for the case where the coverage of the relays may be different, the interference loss can be calculated by considering the coverage overlap area between the relays. In particular, the overlapping area of coverage between each relay device in the path and each relay device in the adjacent path can be calculated as described above, and calculated similarly to the above formula (7), so that the coverage area The larger the overlapping area, the

bigger. In particular, the coverage overlap area can be substituted into formula (7) in an appropriate form, for example instead of

Then the interference loss in this case, especially the maximum interference loss, is obtained.

According to an embodiment of the present disclosure, the bid of the electronic device of the current path to purchase communication resources from a possible seller path with interference is based on the interference coefficient between the buyer path and the seller path, that is, the interference loss calculated above, in particular based on The interference loss caused by the seller's path to the buyer's path. In particular, the reason why the buyer path purchases communication resources from the adjacent seller paths with interference is that the use of the communication resources by the adjacent seller paths will cause interference to itself, so the bid is actually a measure of the impact of this interference. Typically, the greater the interference loss due to the seller path, the higher the bid.

According to an embodiment of the present disclosure, the bid of the electronic device of the current route to the seller route is a random bid that depends on the interference loss with the seller route. Random quotation can avoid the interference of artificially set prices and increase fairness. In particular, when more than one buyer path purchases resources from the seller path, random bidding can increase the fairness of each buyer path obtaining corresponding resources from the seller path.

According to an embodiment of the present disclosure, the random bids follow a Gaussian distribution, wherein the mean and/or variance of the Gaussian distribution is determined based on interference losses between paths. In particular, the mean value of the Gaussian random distribution is based on the maximum value of the spatial interference coefficients between each relay device included in the relay path and the adjacent relay path, and the variance of the Gaussian random distribution is based on the medium The set of spatial interference coefficients between each relay device in the relay path and the adjacent relay path. Therefore, in the case of random distribution, the actual quotation is a random variable, which can ensure the difference between paths and ensure fairness.

According to an embodiment of the present disclosure, redundancy is requested from each of the relay paths and the specified number of adjacent relay paths based on activity statistics about the requested wireless communication resource. free wireless communication resources. That is, regarding the buyer's path requesting communication resources from the seller's path, in addition to considering the interference loss between the paths, the activity statistics of the buyer's path and the seller's path on wireless communication resources to be allocated/requested may also be based. In particular, a buyer path to a seller path's bid for a communication resource may also be determined based on the activity statistics of the buyer path and the seller path regarding wireless communication resources to be allocated/requested.

According to an embodiment of the present disclosure, the activity statistic is a correlation coefficient of the relay path and the adjacent relay path with respect to the activity state of the requested wireless communication resource within a specific time. In particular, the statistical value may be a historical statistical value, and the active state may refer to the usage status of the relay path for the requested resource, that is, if the relay path uses the resource in a certain period of time, it may be considered that the relay path is related to The resource is active. Then, the usage of the communication resource by the two paths and the correlation between the two paths can be determined, so as to determine the activity statistics. According to an embodiment of the present disclosure, the activity statistical information is a statistical value of the common activity state of the relay path and the adjacent relay paths in a specific time with respect to the requested wireless communication resource, and within a specific time, two Statistical value of how the path can all use the resource.

Fig. 7 schematically shows the activity of two relay paths with respect to a certain resource to be allocated, which shows that two paths (path 1, path 2) with respect to a certain bandwidth unit (the spectrum resource may be) in one day will be traded) statistical activity template graph in a typical day, where 1 indicates that the resource is used by the path, and 0 indicates that the resource is not used by the path, so the active statistics about the bandwidth unit of these two paths can be passed through this The overlap of the statistical activity template maps of the two paths is determined, which can be called the path activity correlation coefficient, as follows:

According to an embodiment of the present disclosure, in addition to the spatial interference coefficient, the bid for the requested wireless communication resource by the relay path is further based on activity statistics, such as the aforementioned calculated activity correlation coefficient. Therefore, the bid of the buyer's path to the seller's path can be determined in consideration of the path activity correlation coefficient. The higher the correlation coefficient, the higher the bid should be. Because the buyer path purchases the spectrum of a certain unit bandwidth from the seller path, the goal is that the seller path will no longer use the spectrum, so that the interference disappears, so the greater the interference, the higher the bid should be (for the buyer path, because the interference is removed, the greater the benefit). The larger the correlation coefficient, the greater the possibility of interference caused by the simultaneous use of the two. Therefore, for the buyer path, the price to be paid by purchasing the exclusive use right of this spectrum needs to be higher.

According to an embodiment of the present disclosure, the bid of the buyer's path to the seller's path may be determined based on both the spatial interference coefficient and the activity correlation coefficient of the buyer's path and the seller's path. As an example, the bid of the buyer's path with respect to the seller's path can be considered to be determined by ρ _corr and

The decision, in particular, can be decided by ρ _corr and _rm , for example. According to an embodiment of the present disclosure, bid and q= _rm ·ρ _corr are positively correlated.

According to an embodiment of the present disclosure, when bidding based on both the interference coefficient and the activity correlation coefficient, random bidding, such as Gaussian random distribution, may be used. which uses

The non-zero elements in are calculated to obtain the variance of the random distribution, and q=r _m ·ρ _corr is used as the mean value of the random distribution.

According to an embodiment of the present disclosure, in addition to the buyer path determining the required number of resources and the paths with interference therewith, the electronic device will purchase resources from a specific number of paths with communication interference.

According to an embodiment of the present disclosure, the specific quantity is determined based on the quantity of wireless communication resources to be purchased. As an example, the specific number may depend on the number of spectral bandwidth units the electronic device needs to purchase, as described above. As an example, assuming that the buyer path can only purchase at most one bandwidth unit from one seller path, the number of seller paths is equal to the determined number of spectrum bandwidth units that need to be purchased. For example, the buyer path needs to purchase spectrum resources from |r| seller paths . As another example, if multiple (eg, D) bandwidth units are allowed to be purchased from one vendor path, the vendor path may be virtualized, eg, one vendor path may be virtualized into multiple vendor virtual paths, and the The path asks for a bandwidth unit. In this case, the actual seller path can be |r|/D. Of course, the number of seller paths can also be determined in various appropriate ways based on the number of spectral bandwidth units that need to be purchased, which will not be described in detail here.

According to an embodiment of the present disclosure, the specific number of adjacent relay paths is the first specific number of all adjacent relay paths that have communication interference with the relay path requesting the resource in descending order of possible interference degree. adjacent relay paths, so that bids can be made for these relay paths in turn, where the bids can be set randomly depending on the interference factor as described above. This ensures that as many resources as possible are available.

According to an embodiment of the present disclosure, the specific number of adjacent relay paths are sorted in ascending order according to the combination of the possible interference degree and the activity correlation coefficient among all adjacent relay paths that have communication interference with the requested relay path. The first specified number of adjacent relay paths can be bid on in sequence, where the bids can be set randomly depending on both the interference coefficient and the activity correlation coefficient as previously described. This ensures that as many resources as possible are available.

Furthermore, according to the disclosed embodiments, the sum of the bids of the buyer paths for the specific number of seller paths is less than a specific constraint value. The specific constraint value may be set in any suitable manner and to any suitable value. As an example, resource transactions according to the present disclosure may be performed by means of so-called resource coins, such as bidding and trading in units of resource coins, each resource coin may correspond to each unit of resource, which is expressed as a basic value, such that The specific constraint value is also related to the resource currency, which can be all the resource currency owned by the path before the transaction or a specific percentage of it. As an example, the resource currency possessed by the path may be set to an initial value when the communication system is established, and may be dynamically changed after each transaction as resources are bid for or sold. It should be pointed out that the term resource currency is only used for the purpose of explaining resource transactions more clearly, it is only used to indicate the price paid for obtaining resources, and actually indicates the price/cost paid for seeking resources, for example, it is only a numerical value. .

The buyer path will receive the same amount of resource coins, such as spectrum coins, at the initial stage. Usually, the buyer path will bid to multiple seller paths, and the sum of the bids needs to be less than the total number of spectrum coins in the buyer path. As an example, when a buyer path makes a bid for resources to a seller path set including r seller paths, it is assumed that the bids are in sequence: y1, . . . , yr. At the same time, assuming that the number of spectrum coins currently owned by the buyer path is Cr, it is necessary to constrain the total bid price to be less than the total amount of spectrum coins held, as shown in formula (10).

y ₁ +y ₂ +…+y _r ≤C _r (10)

As an example, since one buyer path may find multiple seller paths, there is a need to bid on multiple seller paths. Assuming that the seller path corresponding to the current buyer path is {Ps1,...,Psv}, each seller path has a corresponding q value, and the order from small to large is {q1,...,qv}. In addition, assuming that the number of spectrum coins owned by the current buyer path is C0, let the quotation for each path be y1,...,yv. Then start from the seller path with the smallest q value, take the corresponding q1 value as the mean value, and the corresponding variance is

Randomly select the value h1 according to the Gaussian distribution, if h1<1, then the quotation of the path is h1C0; then take q2 as the mean value, and the corresponding variance is

The value h2 is randomly selected according to the Gaussian distribution. If h2<1, the quotation of this path is h2(1-h1)C0; the quotation value is continuously performed in this way. Therefore, the path on the resource purchasing side can purchase resources from the path with communication interference in the communication system, so as to satisfy its own communication requirement.

In the structural examples of the apparatus described above, the processing circuit may be in the form of a general-purpose processor, or may be a special-purpose processing circuit, such as an ASIC. For example, the processing circuit can be constructed of a circuit (hardware) or a central processing device such as a central processing unit (CPU). In addition, a program (software) for operating the circuit (hardware) or a central processing device may be carried on the processing circuit. The program can be stored in a memory such as arranged in a memory or an external storage medium connected from the outside, and downloaded via a network such as the Internet.

According to one embodiment, the processing circuit 502 may include various units for implementing the operations described above accordingly, eg, for determining a certain number of adjacent relay paths that may have communication interference with the relay path for requesting redundancy Determining unit 504 of wireless communication resources, the specific number depending on the communication demand of the relay path; and for determining based on the relay path and each of the specific number of adjacent relay paths A requesting unit 506 for requesting redundant wireless communication resources from the adjacent relay path according to the spatial interference coefficient.

Preferably, the requesting unit 506 may further request the adjacent relay path based on the activity statistics about the requested wireless communication resource of each of the relay path and the specific number of adjacent relay paths. Redundant wireless communication resources.

Preferably, the determining unit 504 can also determine the spatial interference coefficient between the paths and the statistical information of the activity between the paths. As another example, the spatial interference coefficient between the paths and the activity statistics between the paths can also be determined by their respective units, which may be different from the determining unit 504, may be included in the processing circuit, or may even be located in outside the processing circuit.

The above-mentioned units can operate as described above, and will not be described in detail here. It should be noted that the above-mentioned units are only logical modules divided according to the specific functions implemented by them, and are not used to limit the specific implementation manner, for example, they may be implemented in software, hardware, or a combination of software and hardware. In actual implementation, each of the above-mentioned units may be implemented as independent physical entities, or may also be implemented by a single entity (eg, a processor (CPU or DSP, etc.), an integrated circuit, etc.). It should be noted that although each unit is shown as a separate unit in FIG. 5 , one or more of these units may also be combined into one unit, or split into multiple units. In addition, the above-mentioned respective units are shown with dotted lines in the drawings to indicate that these units may not actually exist, and the operations/functions implemented by them may be implemented by the processing circuit itself.

It should be understood that FIG. 5 is only a schematic structural configuration of the electronic device on the purchasing side. Optionally, the electronic device 500 on the terminal side may also include other components not shown, such as a memory, a radio frequency link, a baseband processing unit, a network interface, controller etc. The processing circuit may be associated with the memory and/or the antenna. For example, processing circuitry may be connected directly or indirectly (eg, with other components interposed therebetween) to memory for access to data. The memory can store various information acquired and generated by the processing circuit 502 (for example, vehicle interior condition information and its analysis results, etc.), programs and data used for the operation of the purchase-side electronic equipment, data to be sent by the purchase-side electronic equipment, and the like . The memory may also be located within the purchase-side electronics but outside the processing circuitry, or even outside the purchase-side electronics. The memory may be volatile memory and/or non-volatile memory. For example, memory may include, but is not limited to, random access memory (RAM), dynamic random access memory (DRAM), static random access memory (SRAM), read only memory (ROM), flash memory.

Also for example, the processing circuitry may be directly or indirectly connected to the antenna to transmit information and receive requests/instructions via the antenna. For example, by way of example, the antenna may be an omnidirectional antenna and/or a directional antenna, which may be implemented in various ways, such as an antenna array such as both an omnidirectional antenna and a directional antenna, or capable of implementing both an omnidirectional antenna and a directional antenna. Communication components such as a single antenna array) and/or a radio frequency link for the function of the user will not be described in detail here. As an example, the antenna may also be included in the processing circuit, or external to the processing circuit. It may even be coupled/attached to the electronic device 500 without being included in the electronic device 500 .

The electronic device of the wireless communication resource allocation end of the wireless communication system according to the embodiment of the present disclosure will be described below. 8 illustrates an exemplary electronic device 800 of a wireless communication system for allocating/providing a relay path for wireless communication resources having an associated relay path in accordance with an embodiment of the present disclosure Communication coverage, and can provide/allocate idle communication resources to relay paths requesting wireless communication resources. The electronic device 800 includes a processing circuit 802 configured to receive a request for wireless communication resources of the relay path from at least one adjacent relay path with which there may be communication interference with the relay path, each adjacent relay requesting a path based on a spatial interference coefficient between the adjacent relay path and the relay path; and selecting a specific adjacent relay path of the at least one adjacent relay path to allocate the requested wireless communication resources .

According to the embodiments of the present disclosure, a specific relay path can be selected for transaction according to the bid of the relay path for purchasing resources. Here, the adjacent relay path of the bid is the aforementioned buyer path, the bid of which can be determined as described above, and will not be described in detail here.

For a seller path, one or more buyer paths usually receive offers, and at this time, a specific relay path needs to be selected as a transaction object from these bids. According to the present disclosure, various methods can be employed to determine the buyer's relay path as a transaction object.

According to an embodiment of the present disclosure, the adjacent relay path with the highest bid among the at least one adjacent relay path may be selected as the specific relay path for transaction. As an example, the seller relay path usually receives bids from multiple buyer relay paths. In this case, by directly selecting the buyer relay path with the highest bid as the transaction object, the profit can be maximized.

According to an embodiment of the present disclosure, an adjacent relay path with the highest bid in a specific price range among the at least one adjacent relay path may be selected as the specific relay path.

In particular, in order to avoid irrational bidding by one or some buyer relay paths, which will greatly interfere with the fairness of purchases, a reasonable price range can be preset to filter the bids of all buyer relay paths. The buyer's relay path is reserved within the price range, and the relay path with the highest bid is selected from it. If the bid of no relay path is in this range, the idle spectrum resources held will not be traded. In this way, each buyer can be guided to relay more reasonable bids, and at the same time, fairness can be improved, and excessive bids will be invalidated.

The interval can be set in various appropriate ways. According to an embodiment of the present disclosure, the specific price range may be dynamically updated. The following will schematically describe a schematic diagram of a seller path update quotation interval according to an embodiment of the present disclosure with reference to FIG. 9 .

Usually the seller path may receive one or more bids for a bandwidth unit from one or more buyer paths (if it is zero, then there is no need to participate). First, each seller path will maintain a historical quotation range. If the quotation is received for the first time, the buyer path with the highest quotation will be directly selected as the transaction object, and the lowest price of the received quotation will be used as the lower limit of the range, and the highest price is used as the upper limit of the range. If the quotation is not received for the first time, the upper and lower bounds of the quotation range are updated with the newly received quotation. The update principle is as follows. If the average value of all newly received quotations is lower than the lower limit of the original quotation range, the lower limit of the quotation range will be set to this average value, and the upper limit will remain unchanged; if it is higher than the upper limit of the original quotation range, the upper limit of the quotation range will be set. Set the average value, and the lower limit remains unchanged; if the average value is in the original quotation range, the middle value of the original quotation range will be adjusted to the average value. Filter all current quotations according to the updated range, and select the highest quotation in the range as the transaction object.

According to the embodiment of the present disclosure, after the transaction object is determined, transaction information including the selling price and the relevant information of the buyer's relay path for the transaction is notified to the transaction confirmation device/billing electronic device in the wireless communication system for the transaction to be carried out. Transaction confirmation processing.

Similar to that discussed above for the electronics for the resource buyer/buyer path, the processing circuitry for the electronics for the resource seller/seller path, and then for the electronics for the resource seller/seller path, can also be used Various suitable forms are implemented, as described above, and will not be described in detail here.

In particular, according to one embodiment, the processing circuit 802 may include various units for implementing the above-described operations accordingly, eg, for receiving information for the relay path from at least one adjacent relay path that may have communication interference with the relay path. a receiving unit 804 for a request for wireless communication resources of a relay path, the request for each adjacent relay path is based on a spatial interference coefficient between the adjacent relay path and the relay path; and for selecting the The selection unit 806 of the requested wireless communication resource is allocated to a specific adjacent relay path of at least one adjacent relay path. According to one embodiment, the processing circuit further includes a sending unit 808 for sending transaction information containing information about the sale price and the buyer's path to conduct the transaction to the transaction confirmation device in the wireless communication system.

In addition, similar to that discussed above with respect to the electronic device for the resource seeking end, the structure/composition of the electronic device for the resource seeking end described above is merely exemplary.

It should be noted that the above-mentioned units are only logical modules divided according to the specific functions implemented by them, rather than being used to limit the specific implementation manner, which is similar to the description on the aforementioned resource purchasing side, and will not be described in detail here. In addition, similar to the foregoing description on the resource purchasing side, the electronic device on the resource selling side may also include additional or additional units/devices, such as memory, communication interfaces, etc., which will not be described in detail here.

The operation of the transaction confirmation according to the embodiment of the present disclosure will be described below.

According to an embodiment of the present disclosure, based on the blockchain technology, the seller path will send the relevant information of the transaction to a transaction confirmation device, such as a billing electronic device, in the wireless communication system after determining the transaction. The accounting electronic device can summarize the relevant information of all transactions, and then package the transaction information into unauthenticated blocks to send to the appropriate path for transaction authentication. Appropriate paths may include both parties to the transaction, paths that may be affected, and other paths. Preferably, the transaction information is packaged into unauthenticated blocks to be sent to all paths, alternatively, the transaction information can also be packaged into unauthenticated blocks to send paths related to both parties of the transaction, such as may be affected by the communication resources being traded path of.

According to the embodiments of the present disclosure, after each path feeds back the authentication information to the accounting electronic device, the accounting electronic device determines legal transactions according to the rules, and writes the legal transactions into a new block for sending to each node for recording. In particular, for a transaction, the billing electronic device will approve and write the relevant information of the transaction into a new block if the transaction is approved as valid (ie, it can be considered a legitimate transaction). As an example, after the transaction confirmation device collects the authentication information of the transactions in the blocks of all paths, it can judge legal and illegal transactions by voting. Among them, the buyer-seller path (the first type of transaction) has the right to veto the transaction, and the other paths (the second type of transaction) related to this transaction adopt the method of minority obeying the majority. After all transactions are authenticated, the transaction confirmation device puts the block into the blockchain and distributes the block to various paths.

According to an embodiment of the present disclosure, the transaction confirmation device/billing electronic device may be set in any suitable manner. In particular, the billing electronic device may be an electronic device associated with the buyer's path or the seller's path, such as the aforementioned electronic device with The electronic device for resource transactions in the buyer's path or the seller's path, the appropriate electronic device included in the buyer's path or the seller's path, or other electronic device in the system. As mentioned above, it will not be described in detail here.

According to an embodiment of the present disclosure, in the case that the aforementioned electronic device used for resource transaction of the buyer's path or the seller's path can also be used as the electronic device for billing, the processing of the electronic device of the buyer's path or the electronic device of the seller's path The circuit will also perform the operations of the accounting electronics, such as summarizing the relevant information of all transactions, and then packaging the transaction information into an unauthenticated block, which will be sent to the responsible device of each path for authentication. Also, for example, a transaction approval function can be performed, that is, transaction approval is performed based on feedback information about transaction authentication from relevant relay paths, and relevant information of approved valid transactions is written into a new block for transmission to each path in the system. Responsible for equipment.

According to one implementation, the processing circuit of the electronic device on the resource purchase end or the electronic device on the resource seller end as the billing electronic device may include a billing unit that summarizes all transaction-related information and then packages the transaction information into unauthenticated blocks. The reception of transaction-related information and the transmission of unauthenticated blocks may be performed by the receiving and transmitting unit of the electronic device, or may be performed by other suitable communication interfaces. According to another implementation, the accounting unit may also perform transaction approval based on feedback information about transaction authentication from the relevant relay path, and write the relevant information of the approved valid transaction into the new block. Here, the receiving of the feedback information and the sending of the new block may be performed by the receiving and sending unit of the electronic device, or may be performed by other suitable communication interfaces. As an example, the electronic device 500 on the resource buying end may optionally include a billing unit 508, and/or the electronic device 800 on the resource selling end may optionally include a billing unit 810. Of course, the billing unit is optional, and it may Included in the processing circuit, or outside the processing circuit. It should be noted that the generation of authentication blocks and the generation of new blocks after approval can be performed by a single authentication unit as described above, or alternatively by two separate units, for example transaction approval can be performed by a dedicated authorization unit, which Units may be distinct from billing, may be contained within the processing circuit, or may even be located outside the processing circuit. Detailed description will not be desired here.

According to an embodiment of the present disclosure, either the electronic device of the buyer's path or the electronic device of the seller's path participates in transaction authentication. In this case, the electronic device of the buyer's path or the processing circuit of the electronic device of the seller's path will also perform the following operations: receive an authentication block from the billing electronic device in the wireless communication system, the block including the block to be authenticated the communication resource transaction information; authenticate the authentication block, and send the authentication information to the billing electronic device.

According to an embodiment of the present disclosure, a path participating in transaction authentication may perform authentication in an appropriate manner. As an example, for a resource transaction, the electronic device of the buyer's path or the electronic device of the seller's path may perform transaction authentication in different ways according to the degree of association with the resource transaction, especially the degree of influence of the resource transaction. In particular, paths often need to authenticate transactions that they affect.

According to one example, the path participating in the authentication is a participant in a resource transaction, eg as a buyer or seller of this transaction. In this way, when performing authentication, the path mainly checks the information of both parties of the transaction, for example, information such as the bandwidth of the spectrum resource to be traded, and the transaction price. For example, the information sent by the accounting node can be compared with the transaction information. If the information is correct, the transaction is agreed, and the authentication result is fed back to the accounting node.

According to another example, paths participating in authentication are paths that may be affected by resource transactions, such as paths that may be affected by interference after the transaction has occurred. In particular, the path may be the following path: after the transaction, the coverage of the path itself intersects the coverage of the buyer's path, even if the AP in the current path is within the coverage of the buyer's path, such a resource transaction will It may cause interference to the communication of terminals within its coverage area for this path. In this case, the paths participating in the authentication are authenticated based on the level of interference that the buyer's path may cause. If the disturbance exceeds the disturbance tolerance threshold, the transaction is disapproved.

As an example, the interference here mainly refers to that, if the transaction is successful, the APs of the current path exist within the coverage of the APs in the buyer's path, and there is interference between the APs of the buyer's path and the APs of the current path. The interference here may mainly depend on the relative distance of the two APs and the correlation coefficient of the time active templates of the two APs in a certain bandwidth unit, as described above. In this way, the influence of the APs in the buyer's path on the SINR of the APs of the current path can be calculated. According to this, we can also get the influence of the AP in the buyer's path on the SINR of each AP in the current path, denoted as {SINR _c1 ,...,SINR _cN }, and the corresponding interference loss can also be calculated: r _cj =1-SINR _cj /SNR,j∈{1,…,N}. At the same time, the interference loss is multiplied by the respective template correlation coefficient ρ, and then the maximum q value is selected, q _max =max{SINR _cj ·ρ _cj ,j∈{1,...,N}}

If q _max is greater than the set threshold, it is considered that the loss is too large, and the current path does not agree with the transaction; if q _max is not greater than the set threshold, the loss is considered acceptable, and the current path agrees to the transaction.

According to another example, the path that participates in authentication is a path that is not affected by resource transactions. For example, before and after this transaction, communications within the coverage area of this path will not be affected by any interference. Then the path may not need to authenticate the transaction. As another example, or the waiver may be fed back as an authentication result, such an authentication result will not affect the determination of whether the transaction is successful or not.

According to an implementation, the processing circuit of the electronic device that is the resource purchasing end of the accounting electronic device or the electronic device that is the resource selling end may include an authentication unit: an authentication area for the received electronic device from the accounting electronic device in the wireless communication system. The block is authenticated, and the block includes the communication resource transaction information to be authenticated. The reception of the block to be authenticated and the transmission of the authentication information may be performed by the receiving and transmitting unit of the electronic device, or may be performed by other suitable communication interfaces. As an example, the electronic device 500 at the resource purchasing side may optionally include an authentication unit 510, and/or the electronic device 800 at the resource selling end may optionally include an authentication unit 812. Of course, the authentication unit is optional and may be included in the processing In the circuit, it can also be outside the processing circuit.

According to an embodiment of the present disclosure, after the resource transaction is approved, both the electronic device on the resource buying end or the electronic device on the resource selling end can receive the approved communication resource transaction information. In this case, the processing circuit of the electronic device at the resource buying end or the electronic device at the resource selling end is further configured to: receive a block from the billing electronic device in the wireless communication system, the block including the approved communication resources transaction information.

According to one implementation, the receiving of the block may be performed by the receiving unit of the electronic device, or by other suitable communication interface/communication unit.

The above-mentioned units can operate as described above, and will not be described in detail here. It should be noted that the above-mentioned units are only logical modules divided according to the specific functions implemented by them, rather than being used to limit the specific implementation manner, and will not be described in detail here. It should be noted that the above-mentioned billing unit, authentication unit, etc. are optional and are shown in dashed lines in the drawings.

The method for a purchase end of a wireless communication system according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings. FIG. 10 shows a flowchart of a method 1000 for a purchase end of a wireless communication system according to an embodiment of the present disclosure.

In step S1001, a specific number of adjacent relay paths that may have communication interference with the relay paths are determined for requesting redundant wireless communication resources, the specific number being dependent on the communication requirements of the relay paths.

In step S1002, redundant wireless communication resources are requested from the adjacent relay paths based on the spatial interference coefficient between the relay path and each of the specified number of adjacent relay paths.

In addition, the method may further include corresponding steps for implementing the operations performed by the electronic device of the buyer's path described above, particularly including the steps of performing authentication operations and the steps of receiving confirmation information after the transaction is completed. In addition, if the electronic device of the buyer's route can be used as the billing electronic device, the method for the buyer's route will also include the steps of performing the billing operation described above, and the description will not be repeated here. It should be noted that, depending on the role and function of the electronic device in the transaction process, steps S1003 to S1005 are not necessary and are therefore indicated by dotted lines in the drawing.

It should be noted that these steps may be performed by the aforementioned electronic device according to the buyer's path of the present disclosure, in particular by corresponding units of the aforementioned electronic device according to the buyer's path of the present disclosure.

The method for a wireless communication system resource seller according to an embodiment of the present disclosure will be described below with reference to the accompanying drawings. FIG. 11 shows a flowchart of a method 1100 for a wireless communication system purchase end according to an embodiment of the present disclosure.

In step S1101, a request for wireless communication resources of the relay path from at least one adjacent relay path that may have communication interference with the relay path is received, and the request for each adjacent relay path is based on the adjacent relay path. The spatial interference coefficient between the relay path and the relay path.

In step S1102, a specific adjacent relay path among the at least one adjacent relay path is selected to allocate the requested wireless communication resource.

In addition, the method may further include corresponding steps to implement the operations performed by the electronic device of the seller path described above, particularly including the steps of performing authentication operations and the steps of receiving confirmation information after the transaction is completed. Furthermore, if the electronic device of the seller's route is to be used as a billing electronic device, the method for the seller's route will also include the steps of performing the billing operations described above, which will not be repeated here. It should be noted that, depending on the role and function of the electronic device in the transaction process, steps S1103 to S1105 are not necessary and are therefore indicated by dotted lines in the drawing.

It should be noted that these steps may be performed by the aforementioned electronic device of the seller path according to the present disclosure, in particular by corresponding units of the aforementioned electronic device according to the seller path of the present disclosure.

The present disclosure proposes a communication network for multiple relay paths in a communication scenario, and adopts the blockchain technology to perform flexible and reasonable allocation of communication resources among different paths. Among them, the relay path will adjust the demand of communication resources according to the communication requirements, and then buy or sell communication resources from the adjacent relay paths, so that the resources of each path can be dynamically adjusted and the utilization efficiency of resources can be improved.

In particular, communication resource transactions between relay paths can be performed based on blockchain technology. As an example, a differentiated self-organizing private network is constructed according to the actual communication needs of relay paths in different areas in the scenario to conduct communication resource transactions based on blockchain technology, where the relay paths can dynamically change the number of terminals that need to be served within the coverage area. or communication needs to adjust the sale and purchase status of its own spectrum resources. In operation, all transactions constitute blocks to be authenticated to be authenticated by the relevant paths, and after confirming the agreed transactions, new blocks are formed and distributed to each relay path for recording, so that the use of blockchain can improve the security of information interaction .

In the present disclosure, the dynamic allocation of communication resources between relay paths especially considers the mutual interference between different paths as the pricing and driving factor of spectrum resource transactions, wherein the interference of different paths is essentially the interference of multiple groups of APs to APs. Considering it comprehensively, the essence of requesting to allocate communication resources is to eliminate the interference effect on the buyer's AP when the seller's AP uses the spectrum. In particular, the mutual interference between paths takes into account the geographic location information of APs in each path and the statistical template of the daily spectrum activity of buyers and sellers for a certain candidate bandwidth unit, and makes corresponding transaction quotations according to the degree of interference, The larger the disturbance, the higher the bid accordingly, in order to eliminate the disturbance effect as much as possible.

Therefore, based on the blockchain technology, the present disclosure conducts reasonable transactions of spectrum resources for multiple APs in the system scenario to adapt to the needs of data traffic in different regions, thereby improving the overall utilization of communication resources in the entire system scenario. efficiency, and further improve the security of transactions.

specific example

Usually in addition to the common cellular network, for simpler and customized communication, sometimes some enterprises or factories will establish some private networks. The frequency bands used by these networks may be unlicensed frequency bands or shared frequency bands that do not interfere with primary users, such as broadcast television white spectrum (TVWS) or the open CBRS frequency bands in the United States. Assuming that these frequency bands are shared by multiple APs in an area, there will be spectrum allocation problems among multiple APs. Here, we use blockchain technology to realize the transaction of spectrum resources between various relay paths. The specific embodiment scenario is shown in Figure 12. There are four paths in the scenario. Each path determines its own role (buyer path or seller path, and the need to purchase or the number of bandwidth units that can be sold). Here, it is assumed that after calculation, path 2 and path 3 are buyers (each wants to buy 1 bandwidth unit), and path 1 and path 4 are sellers (each can sell one bandwidth unit). Path 2 uses the method mentioned above to determine the transaction price for Path 1 and Path 4, and Path 3 also uses this method to determine the transaction price for Path 1 and Path 4. Here, we assume that path 4 uses the method proposed above to determine the offer of accepting path 2, and path 1 also uses a similar method to determine the offer of accepting path 3. That is, two transactions are drawn up. Path 4 sells the spectrum of a single bandwidth unit to Path 2 at the agreed price, and Path 1 sells the spectrum of a single bandwidth unit to Path 3 at the agreed price.

Here we take the transaction between path 4 and path 2 as an example (as shown in Figure 12) to illustrate the authentication process of this transaction by all paths. First, the seller path 4 sends the proposed transaction information (including transaction price, path information of both parties to the transaction, attribute information of a single bandwidth unit of the transaction, etc.) to the transaction confirmation device. The transaction confirmation device, after aggregating all proposed transactions, forms a new unauthenticated block, which is then distributed to all paths. Path 2 and Path 4 are the participants of this transaction. After checking that the information is correct, they confirm that they agree to the transaction (if they are wrong, deny the transaction). After this transaction occurs, path 1 may be disturbed, and the above-mentioned determination method can be used to confirm the operation. Path 3 will not be affected by any interference after this transaction, so no authentication is required. The authentication of this transaction by all paths will eventually be gathered on the proxy manager, and the proxy manager uses the fifth part of the voting method for final confirmation. If the transaction is considered valid, it is written into a new block; otherwise, the transaction is discarded.

first example

14 is a block diagram showing a first example of a schematic configuration of a gNB to which techniques of the present disclosure may be applied. gNB 1700 includes multiple antennas 1710 and base station equipment 1720. The base station apparatus 1720 and each antenna 1710 may be connected to each other via an RF cable. In an implementation manner, the gNB 1700 (or the base station device 1720) here may correspond to the above-mentioned control-side electronic device.

Each of the antennas 1710 includes a single or multiple antenna elements (such as multiple antenna elements included in a multiple-input multiple-output (MIMO) antenna), and is used by the base station apparatus 1720 to transmit and receive wireless signals. As shown in FIG. 14, gNB 1700 may include multiple antennas 1710. For example, multiple antennas 1710 may be compatible with multiple frequency bands used by gNB 1700.

The base station apparatus 1720 includes a controller 1721 , a memory 1722 , a network interface 1717 , and a wireless communication interface 1725 .

The controller 1721 may be, for example, a CPU or a DSP, and operates various functions of a higher layer of the base station apparatus 1720 . For example, the controller 1721 determines the location of the target terminal device in the at least one terminal device according to the positioning information of the at least one terminal device on the terminal side in the wireless communication system and the specific location configuration information of the at least one terminal device acquired by the wireless communication interface 1725 . location information.

This control can be performed in conjunction with nearby gNB or core network nodes. The memory 1722 includes RAM and ROM, and stores programs executed by the controller 1721 and various types of control data such as a terminal list, transmission power data, and scheduling data.

The network interface 1723 is a communication interface for connecting the base station apparatus 1720 to the core network 1724 .

In this case, gNB 1700 and core network nodes or other gNBs may be connected to each other through logical interfaces such as S1 interface and X2 interface. The network interface 1723 may also be a wired communication interface or a wireless communication interface for wireless backhaul. If the network interface 1723 is a wireless communication interface, the network interface 1723 may use a higher frequency band for wireless communication than the frequency band used by the wireless communication interface 1725 .

The BB processor 1726 may be a memory storing a communication control program, or a module including a processor and associated circuitry configured to execute the program. The update procedure may cause the functionality of the BB processor 1726 to change. The module may be a card or blade that is inserted into a slot in the base station device 1720. Alternatively, the module can also be a chip mounted on a card or blade. Meanwhile, the RF circuit 1727 may include, for example, a mixer, a filter, and an amplifier, and transmit and receive wireless signals via the antenna 1710.

As shown in FIG. 14 , the wireless communication interface 1725 may include a plurality of RF circuits 1727 . For example, multiple RF circuits 1727 may be compatible with multiple antenna elements. Although FIG. 14 shows an example in which the wireless communication interface 1725 includes multiple BB processors 1726 and multiple RF circuits 1727 , the wireless communication interface 1725 may also include a single BB processor 1726 or a single RF circuit 1727 .
