Taking a node in a wireless communication system to communicate through a frequency domain channel resource as an example, a frequency domain channel resource in a wireless communication system generally includes an authorized frequency domain channel resource and an unauthorised frequency domain channel resource. When nodes communicate with authorized frequency domain channel resources, channel resources planning for frequency domain channel resources can be used to eliminate and reduce interference between adjacent nodes, but when nodes communicate with each other through unlicensed frequency domain channel resources. Because channel resource planning cannot be performed, the interference problem caused by communication between nodes is very complicated and difficult to solve.

The first node in the embodiment of the present invention may be a node in a wireless communication system, such as a WLAN, that needs to communicate with other nodes, and the interference node may be between the wireless node and the first node. There are nodes that interfere with each other; for example, the first node and the interfering node may be nodes located at the network side, such as an access point (AP), a base station (Node B), etc., so as to implement negotiation of radio resources between the network side nodes.

[89] FIG. 3 is a schematic diagram of a first embodiment of a resource negotiation method according to the present invention, where the method includes:

[90] Step 301: The first node determines an interference node that interferes with the first node.

[91] The interference node may be one or more. When the number of the interference nodes is multiple, the following steps 302 to 306 are performed between the first node and each of the interference nodes.

[92] The first node may obtain information of the interference node that interferes with the first node in a passive or active manner. In the passive mode, the first node may obtain the information of the interfering node by detecting the sending address or the sending node identifier in the sending frame of the neighboring node on the working frequency domain channel resource; in the active mode, the first node may The request frame is sent on the working frequency domain channel resource, and the information of the interference node is obtained by detecting the response frame fed back by the neighbor node.

[93] The request frame and the response frame may be implemented by using an existing data frame structure, or may be defined autonomously in an actual application, which is not limited herein.

[94] Step 302: The first node sends a resource negotiation request frame to the interference node, where the resource negotiation request frame is used to request the interference node to perform resource negotiation with the first node.

[00] Step 303: The first node receives the resource negotiation confirmation frame sent by the interference node, where the resource negotiation confirmation frame is used to indicate that the interference node of the first node agrees to perform resource negotiation.

[96] The resource negotiation request frame and the resource negotiation confirmation frame may be implemented by using an existing data frame structure, or may be defined autonomously in an actual application, which is not limited herein.

[97] Step 302 and step 303 are optional steps. In addition, step 302 and step 303 may also be performed before the step 305 is performed after the authentication is passed in step 304.

[98] Step 304: Perform security authentication between the first node and the interfering node. After the authentication is passed, perform step 305. When the authentication fails, the processing between the first node and the interfering node ends.

[99] The implementation method for performing security authentication between the first node and the interfering node in this step is described in detail in FIG. 4 and FIG. 5, and details are not described herein.

[100] Step 305: The first node acquires radio environment related information of the interfering node and a resource negotiation policy that is negotiated with the interfering node.

[101] The wireless environment related information of the interference node may include at least one of the following information: a list of interference nodes that interfere with the interference node, a channel list obtainable by the interference node, and the interference The load condition information of each channel that can be obtained by the node, the load condition information of the interfering node, and the like. The channel list obtainable by the interfering node refers to a channel that the interfering node is currently working on and a channel that can work after being negotiated according to its capabilities and wishes. [102] wherein the resource negotiation policy is optional information; for example, when the first node and each interfering node support only the same resource negotiation policy, for example, respectively, the first node and each interfering node are already set. When the resource negotiation policy is the same, the first node does not need to obtain the resource negotiation policy that is negotiated with the interfering node, and directly negotiates according to the preset resource negotiation policy in the subsequent step 306. .

[103] The resource negotiation policy refers to a policy followed by radio resource negotiation between nodes. The main purpose of the resource negotiation policy setting is that the first node and the interfering node negotiate according to the resource negotiation policy, and the radio resources that the first node can obtain are only allocated to the first node or are allocated to the first node and Part or all interfere with the node to avoid or reduce the occurrence of collisions. The implementation of the resource negotiation policy can be implemented in many ways. Generally, the resources are negotiated according to the same resource negotiation policy to avoid unfairness between nodes and reduce the collision probability of the negotiation result.

[108] The first node receives wireless environment related information of the interference node sent by the interference node.

[112] The first node obtains the resource negotiation policy supported by the corresponding interfering node from the resource negotiation confirmation frame, and uses the obtained resource negotiation policy as a resource negotiation policy that is negotiated with the interfering node; In a second possible implementation, if the interfering node supports only one resource negotiation policy, and the resource negotiation policy is not carried in the resource negotiation acknowledgement frame sent by the interfering node, but is transmitted to the A resource negotiation policy that the first node obtains to negotiate with the interfering node may include:

[113] The first node receives the resource negotiation policy supported by the interference node sent by the interference node, and uses the received resource negotiation policy as a resource negotiation policy that is negotiated with the interference node.

Optionally, the resource negotiation policy may be carried in the data frame by the interfering node to the first node.

[115] In a third possible implementation, if the interfering node supports at least two resource negotiation policies, and the resource negotiation policy information formed by the at least two resource negotiation policies carries the resource negotiation sent by the interfering node. In the acknowledgment frame, the resource negotiation policy that the first node obtains to negotiate with the interfering node may include:

[116] The first node obtains the resource negotiation policy information of the corresponding interfering node from the resource negotiation confirmation frame, and selects a resource negotiation policy supported by the first node from the voluntary negotiation policy information to negotiate with the interference node. The resource negotiation policy is followed, and the information about the selected resource negotiation policy is sent to the interference node.

[117] In a fourth possible implementation, if the interfering node supports the at least two resource negotiation policies, and the resource negotiation policy information that is formed by the at least two resource negotiation policies does not carry the resources sent by the interfering node The negotiation confirmation frame is transmitted to the first node by other means, and the resource negotiation policy that the first node obtains to negotiate with the interference node may include:

[118] The first node receives the resource negotiation policy information supported by the interference node sent by the interference node; the first node selects a resource negotiation policy supported by the first node from the received resource negotiation policy information as And the interference negotiation node negotiates the resource negotiation policy, and sends the information of the selected resource negotiation policy to the interference node.

Optionally, the resource negotiation policy information may be carried in a data frame for transmission.

[120] Optionally, the information of the selected resource negotiation policy may be carried in a data frame for transmission.

[121] Optionally, the wireless environment related information and the resource negotiation policy or resource negotiation policy information may be carried in the same or different data frames.

[122] The resource negotiation confirmation frame may also include only the radio environment related information of the interfering node, and the resource negotiation policy supported by the interfering node or the resource negotiation policy information of the interfering node may be used by the interfering node by other means, for example, other Sending a data frame to the first node; or, the resource negotiation confirmation The frame may also include only the resource negotiation policy supported by the interfering node or the resource negotiation policy information of the interfering node, and the radio environment related information of the interfering node may be sent by the interfering node to the first node by other means, such as other data frames.

[123] The resource negotiation request frame in step 302 may also include: information about the wireless environment of the first node and/or information of the resource negotiation policy supported by the first node, so as to interfere with the node and the interference node. The own interfering node negotiates the radio resources used by itself;

[124] Alternatively, the resource negotiation request frame may not include: the wireless environment related information of the first node and/or the information of the resource negotiation policy supported by the first node, etc., but is transmitted by the first node through other frames. Give the interference node. The wireless environment related information of the first node and the resource negotiation policy supported by the first node may be transmitted using the same or different frames.

[125] Step 306: The first node negotiates the radio resource used by the first node with the interfering node according to the radio environment related information of the first node, the radio environment related information of the interfering node, and the resource negotiation policy negotiated with the interfering node. .

[126] The wireless environment related information of the first node may include: a list of interference nodes that interfere with the first node, and/or a channel list obtainable by the first node, and/or the first Load condition information of each channel available to the node, and/or load condition information of the first node.

[127] In practical applications, the wireless environment related information of the first node and the specific information included in the wireless environment related information of the interference node should be consistent, for example, the first node may include the first node in the wireless environment related information. The channel list, then the information about the wireless environment of the interfering node preferably includes the channel list available to the interfering node, so that the first node can obtain more comprehensive information when negotiating with the interfering node for radio resources, so that the negotiation result is obtained. More accurate.

[128] In a first possible implementation manner, the first node and the interference node may negotiate that the radio resource used by the first node may be completely distributed. Specifically, the first node is configured according to the wireless environment of the first node. The related information, the wireless environment related information of the interfering node, and the resource negotiation policy that is negotiated with the interfering node, and the radio resource used by the first node to negotiate with the interfering node may include:

[130] The first node uses the determined radio resource as the radio resource used by the first node, and sends the information of the radio resource to each interfering node.

[131] In this implementation, since the first node can only obtain local information in the wireless communication system, The determined radio resource used by the first node may overlap with the radio resource used by the interfering node determined by the interfering node. In this case, the two may share overlapping frequency domain channel resources through a contention mechanism, which is not described herein. .

In a second possible implementation, the first node and the interference node may negotiate that the radio resource used by the first node may be interactive. Specifically, the first node is related to the wireless environment of the first node. The information, the information about the wireless environment of the interfering node, and the resource negotiation policy that is negotiated with the interfering node, and the radio resource used by the interfering node to negotiate with the interfering node may include:

[134] The first node sends the determined information of the radio resource to each interfering node for confirmation;

[135] After receiving the consent response sent by each interfering node, the first node uses the radio resource as the radio resource used by the first node.

In this implementation, the first node sends the information of the radio resource to each interfering node, and if the interfering node agrees, replies to the acknowledgment response, and if the interfering node disagrees, replies the refusal response. The first node can use the corresponding radio resource as the radio resource used by its own work only after all the interfering nodes reply the consent response. Otherwise, the radio resource corresponding to the first node needs to be re-determined and then the acknowledgement is sent to the interfering node again. request.

[137] Hereinafter, the implementation of this step will be further described by taking a radio resource as a frequency domain channel resource as an example.

In a first possible implementation, the first node negotiates with the interfering node according to the radio environment related information of the first node, the radio environment related information of the interfering node, and the resource negotiation policy negotiated with the interfering node. The frequency domain channel resources used by a node may include:

Determining, by the first node, the first node according to the wireless environment related information of the first node, the wireless environment related information of the interference node, and the resource negotiation policy negotiated with the interference node. Frequency domain channel resources;

[140] The first node uses the determined frequency domain channel resource as the frequency domain channel resource used by the first node, and sends the information of the frequency domain channel resource to each interference node.

[141] In this implementation manner, since the first node can only obtain local information in the wireless communication system, the determined frequency domain channel resource used by the first node and the frequency used by the interference node determined by the interference node are determined. The domain channel resources may overlap. In this case, the two can share overlapping frequency domain channel resources through the contention mechanism, which is not described here. [142] In a second possible implementation, the first node negotiates with the interfering node according to the radio environment related information of the first node, the radio environment related information of the interfering node, and the resource negotiation policy negotiated with the interfering node. The frequency domain channel resources used by a node may include:

[144] The first node sends the determined information of the frequency domain channel resource to each interference node for confirmation;

[145] After receiving the consent response sent by each interfering node for the acknowledgment, the first node uses the frequency domain channel resource as the frequency domain channel resource used by the first node.

In this implementation, the first node transmits the information of the frequency domain channel resource to each interference node, and if the interference node agrees, replies to the consent response, and if the interference node does not agree, the response refusal. The first node can use the corresponding frequency domain channel resource as the frequency domain channel resource used by itself only after all the interfering nodes reply the consent response. Otherwise, the frequency domain channel resource corresponding to the first node needs to be re-determined and then again. A confirmation request is sent to the interfering node.

[147] The following is a more detailed description of the resource negotiation strategy.

[148] Generally, the resource negotiation policy is related to specific information included in the wireless environment related information of the node, where the node may include: a first node and an interference node.

[149] In a possible implementation, the resource negotiation algorithm may be set as a resource negotiation policy according to one or more information in the wireless environment related information as an input parameter, and the wireless resource is used as an output parameter, for example:

[150] If the wireless environment related information of the node includes an interference node list that interferes with the node, the resource negotiation policy may include: determining, according to the interference node list, between the first node, the interference node, and the interference node of the interference node. a topological relationship; allocating a total radio resource obtainable by the first node according to the topology relationship;

[151] If the wireless environment related information of the node includes a channel list that is available to the node, the resource negotiation policy may include: when determining the wireless resource for the first node, the interference node may be excluded from the channel list obtainable by the first node. Channel in the channel list; for example, when a channel is occupied by a radar or has been allocated to an interfering node by negotiation, the channel is not available to the first node, so the first node is in interference with The channel needs to be excluded when the node negotiates radio resources.

[152] If the wireless environment related information of the node includes the load situation information of each channel that the node can obtain, the resource negotiation policy may include: dividing the channel resources between the nodes; The channel resources available to the interfering node and the interfering node are equally divided according to the load condition information of each channel that the interfering node can obtain, and the channel resources used by the first node are negotiated with the interfering node. It should be noted that when performing channel resource division, it is generally considered that different load between channels may result in different transmission rates that the same width or number of channels can support, so as to avoid unfairness of the negotiation process.

[153] If the wireless environment related information of the node includes the load situation information of the node, the resource negotiation policy may include: allocating the total wireless resources available to the first node according to the interference node and the load of the first node. For example, if the radio resource is a frequency domain channel resource, the load of the interfering node is Pi p ₂ , - pk, the load of the first node is p _Q , and the total frequency domain channel resource obtainable by the first node is S, In the resource negotiation with the interfering node, the frequency domain channel resource width obtainable by the first node does not exceed

So=S* p ₀ /( po+p ₁ +~+Pk).

[154] In the following, the wireless environment related information of the node includes the load situation information of the node, and the resource negotiation policy is used to allocate the frequency domain channel resource according to the interference node and the load of the first node, and how to implement the determination in step 306. The frequency domain channel resources corresponding to the first node are described in more detail.

In a first possible implementation manner, the determining, by the first node, the frequency domain channel resource corresponding to the first node according to the wireless environment related information and the resource negotiation policy may include:

[156] The first node determines, according to the load of the first node and the interfering node, and the resource negotiation policy, a frequency domain channel resource width obtainable by the first node and the interfering node;

[157] The first node performs the ordering of the first node and the interfering node according to the first node and the MAC address of the interfering node;

[158] The first node determines the frequency domain channel resource corresponding to the first node from the total frequency domain channel resources according to the sorting order and the frequency domain channel resource width obtainable by each node.

[159] The total frequency domain channel resource may include: all frequency domain channel resources that the first node can acquire.

[160] wherein the method is particularly applicable to the first possible implementation of step 306 above.

[161] For example, if the sorting order of the first node is i, then the frequency domain channel resource width corresponding to the first node may be determined according to the frequency domain channel resource width that can be obtained by the interfering node that is sorted by l~il. The starting position of the first node, the frequency domain channel resource width obtainable by the first node may determine the end position of the frequency domain channel resource corresponding to the first node in the total frequency domain channel resource, thereby determining the frequency domain corresponding to the first node Channel resources. The width of the frequency domain channel resource corresponding to the first node may be equal to or smaller than the frequency domain channel resource width obtainable by the first node. [162] In a second possible implementation, the determining, by the first node, the frequency domain channel resource corresponding to the first node, according to the information about the wireless environment and the resource negotiation policy, may include:

[163] The first node determines, according to the load of the first node and the interfering node, and the resource negotiation policy, a frequency domain channel resource width obtainable by the first node;

[164] The first node randomly selects the frequency domain channel resource corresponding to the first node from the total frequency domain channel resources according to the frequency domain channel resource width obtainable by the first node.

[165] The total frequency domain channel resource may include: all frequency domain channel resources that the first node can acquire.

This method is particularly applicable to the second possible implementation of step 306 above.

[167] wherein the width of the frequency domain channel resource used by the first node may be less than or equal to the frequency domain channel resource width obtainable by the first node.

In this embodiment, the first node negotiates with the interfering node the radio resources used by the first node, and does not need to additionally set the resource management node, thereby reducing the complexity of the network architecture of the wireless communication system; The wireless resources used by the first node are negotiated with the interference nodes of the first node, and the data processing amount of the resource management node in the prior art is dispersed to each node, thereby improving the efficiency of allocating wireless resources to the nodes; The related information and the resource negotiation policy information negotiate the radio resource used by the first node with the interfering node, so that the first node radio resource can be allocated to the radio environment of the first node and its interfering node, which can be more advanced than the prior art. To accurately perform wireless resource allocation of nodes;

[169] Moreover, before the wireless environment related information and the supported resource negotiation policy are transmitted between the first node and the interfering node, the security authentication is performed first, thereby ensuring the security of resource negotiation between the first node and the interfering node.

[170] For step 302, the security authentication may be performed by the public key encryption method between the first node and the interfering node of the first node.

[171] The public key encryption method uses an asymmetric key, including a pair of keys, an encryption key and a decryption key. These two keys are mathematically related. When a certain information is encrypted by an encryption key, only The corresponding decryption key can be used to decrypt the information. Moreover, if one of the keys is known, and another key paired with the key cannot be calculated, if one of the pair of keys is disclosed, the other key will not be compromised. The secret nature. The public key is called a public key, and the undisclosed key is called a private key.

In a possible implementation manner of the embodiment of the present invention, a wireless communication system such as a WLAN may be used. A public key server is set in the system, and the public key of each node is stored in the public key server. Each node can communicate with a public key server, see for example Figure 3A. Through the public key server, each node can obtain the public key of any other node. Any form of communication connection can be used between the node and the public key server, for example, the node communicates with the public key server via Ethernet, and the like. In the embodiment of the present invention, although the public key server is also connected to each node, it is substantially different from the resource management node described in the prior art, that is, the resource management node maintains a resource database, and according to the database All nodes allocate resources, and the public key server is only responsible for managing the public keys of each node, and does not directly participate in the negotiation and allocation of resources.

[173] In the first possible implementation manner, as shown in FIG. 4, the method for implementing security authentication between the first node and the interfering node may include:

[174] Step 401: The first node sends, to the interfering node, the first encrypted information encrypted by using the private key of the first node;

[175] Step 402: The interfering node requests the public key of the first node from the public key server;

[176] Step 403: The public key server sends the public key of the first node to the interference node;

[177] Step 404: The interfering node decrypts the first encrypted information by using the public key of the first node. If the decryption is unsuccessful, the interfering node fails to pass the first node security authentication; if the decryption succeeds, the interfering node pairs the first After the node security authentication is passed, step 405 is performed.

[178] Step 405: The interfering node sends the second encrypted information encrypted by the private key of the interfering node to the first node.

[179] Step 406: The first node requests the public key server to interfere with the public key of the node;

[180] Step 407: The public key server sends the public key of the interfering node to the first node;

[181] Step 408: The first node decrypts the second encrypted information by using the public key of the interfering node. If the decryption is unsuccessful, the first node does not pass the security authentication of the interfering node; if the decryption succeeds, the first node interferes with the first node. The node security certification is passed.

Optionally, the first encryption information may be carried in the resource negotiation request frame, and the second encryption information may be carried in the resource negotiation confirmation frame.

[183] Optionally, the interaction of information between the interference node and the first node may be implemented by means of frame interaction.

In a second possible implementation manner, as shown in FIG. 5, the method for implementing security authentication between the first node and the interfering node may include:

[185] Step 501: The first node requests the public key server to interfere with the public key of the node;

[186] Step 502: The public key server sends the public key of the interfering node to the first node; [187] Step 503: The first node encrypts the first problem information by using the public key of the interfering node, and sends the obtained third encrypted information to the interfering node;

[188] Step 504: The interfering node decrypts the third encrypted information by using its own private key, and solves the first problem information obtained by decrypting to obtain the first answer information.

[189] Step 505: The interfering node requests the public key of the first node from the public key server;

[190] Step 506: The public key server sends the public key of the first node to the interference node;

[191] Step 507: The interference node encrypts the second problem information by using the public key of the first node, and sends the obtained fourth encrypted information and the first solution information to the first node.

[192] Step 508: The first node verifies the first answer information. If the verification passes, step 509 is performed; if the verification fails, the security authentication between the first node and the interfering node fails, and the authentication process ends.

[193] Step 509: The first node decrypts the fourth encrypted information by using its own private key, and answers the decrypted second question information to obtain second answer information, and sends the second answer information to the interference node. ;

[194] Step 5 10: The interference node verifies the second solution information, if the verification passes, the security authentication between the interference node and the first node passes; if the verification fails, the first node and the interference node The security certification did not pass and the certification process ended.

[195] The third encrypted information may be carried in the resource negotiation request frame, where the fourth encrypted information and the first solution information may be carried in the resource negotiation confirmation frame.

[196] Through the security authentication methods of Figures 4 and 5 above, the security authentication between the first node and the interfering node can be achieved. However, the security authentication method shown in FIG. 4 and FIG. 5 above is only an example. In practical applications, the security authentication method shown in FIG. 4 and FIG. 5 may be modified, or the other security authentication method may be used to implement the first method.
