Description

Data transmission method and device

The present invention relates to the field of communications, and in particular, to a data transmission method and device.

Background technique

With the rapid development of data communication, users' demand for data transmission is increasing, making the load of wireless networks more and more heavy. In order to make full use of spectrum resources and meet the increasing data transmission requirements, carrier aggregation technology emerges. Carrier aggregation That is, two or more component carriers are aggregated to form a large bandwidth channel to transmit data, thereby meeting the requirements of larger bandwidth and higher data transmission rate. Carrier aggregation can be divided into continuous carrier aggregation and discontinuous carrier aggregation.

Currently, in the existing mechanism of the 802.11, the spectrum resources managed by the AP (Access Point) device are divided into a primary carrier and a secondary carrier, and the signal transmission bandwidth is increased to increase the peak rate of data transmission. The mechanism in 802.11 is similar to carrier aggregation, which requires carrier-to-carrier access. For example, when the channel bandwidth is 160MHz, the order of carrier competing access is mainly 20MHz carrier, secondary 20MHz carrier, auxiliary 40MHz carrier, and auxiliary 80MHz carrier. In this order, only when the previous carrier is allowed to access, the AP device or the STA (station, user equipment) will perform the competing access of the latter carrier, and finally combine the carriers that are allowed to access to form a large Bandwidth channel to transmit data.

However, at present, the frequency resource resources managed by each AP device only establish one BSS (Basic Service Set), and the BSS is an independent communication system. Correspondingly, the spectrum resources corresponding to the BSS are divided into a primary carrier and a secondary carrier. Regardless of the bandwidth of the BSS, the primary carrier is always fixed. When the spectrum resource where the primary carrier is located is occupied by other devices, the spectrum resource cannot be used to transmit the unique BSS data managed by the AP device. The transmission of data by the user equipment on the spectrum resource and the AP device is affected, and the data transmission efficiency of the user equipment is reduced.

In addition, the character "/" in this article generally indicates that the contextual object is an "or" relationship.

The data transmission method provided by the embodiment of the present invention is applied to a wireless local area network, where the wireless local area network includes multiple AP devices and multiple user equipments, and each of the AP devices manages a specific piece of spectrum resources, and the AP device can be managed by the AP device. The spectrum resources and the corresponding user equipment for data transmission.

An embodiment of the present invention provides a data transmission method, which is applied to a user equipment, as shown in FIG. 1 , and includes:

Step 101: Acquire a primary BSS and a secondary BSS allocated by the AP device to the user equipment. It should be noted that, before step 101, the user equipment needs to establish a connection with the AP device. Optionally, the user equipment determines whether the detected BSS supports BSS aggregation, and the detected BSS is a BSS established by the AP device. Determining whether the user equipment supports BSS aggregation; when the detected BSS supports BSS aggregation and the user equipment supports BSS aggregation, sending, in the detected BSS, an AP device that manages the detected BSS Requesting information, so as to obtain a primary BSS and a secondary BSS allocated by the AP device to the user equipment after establishing a connection with the AP device.

The obtaining the primary basic service set BSS and the secondary BSS of the user equipment that the AP device allocates to the user equipment includes: receiving a BSS aggregation list of the current primary BSS sent by the AP device, or acquiring the current current local saved by the user equipment a BSS aggregation list of the primary BSS, the BSS aggregation list records at least one BSS to be measured; receives BSS measurement information sent by the AP device, or acquires BSS measurement information locally saved by the user equipment, and the BSS measurement information record Having a measurement rule; measuring the BSS to be measured according to the BSS measurement information; transmitting, in the primary BSS, the measured channel quality of the BSS to be measured to the AP device, and carrier aggregation supported by the user equipment The capability of the AP device to generate a primary BSS indication and a secondary BSS list of the user equipment according to the channel quality of the BSS to be measured and the carrier aggregation capability supported by the user equipment, where the secondary BSS list is Including at least one secondary BSS indication, the primary BSS indication is used to indicate that the user equipment needs to be connected BSS, BSS indicates to the secondary auxiliary BSS instructing the user equipment to be connected; delivered by the AP receiving the device information about the device, the device-related information comprises an indication of said primary and said secondary BSS BSS list.

In particular, the BSS in the BSS list may be from a BSS constructed in different situations. For example, the secondary BSS allocated by the AP device to the first user equipment is a BSS managed by the AP device; and/or The secondary BSS allocated by the AP device to the first user equipment is a BSS managed by another AP device; and/or the secondary BSS allocated by the AP device to the first user equipment is established by at least two user equipments. The BSS, wherein the at least two user equipments may include the local user equipment or the local user equipment, which is not limited by the disclosure. Step 102: Perform data transmission in the primary BSS and the secondary BSS. The user equipment accepts management of the AP device in the primary BSS. For example, the user equipment may receive, in the primary BSS, new device-related information that is sent by the AP device, where the new device-related information is that the AP device adds a BSS to the spectrum resource managed by the AP device. Thereafter, and/or generated after deleting the BSS in the spectrum resource managed by the AP device; comparing the locally saved device related information with the new device related information; if the locally saved device related information is the primary The BSS indication is different from the primary BSS indication in the new device related information, and the user equipment is switched to the primary BSS indicated by the primary BSS indication in the new device related information; if the locally saved device related information The secondary BSS list in the new device related information is different from the secondary BSS list in the new device related information, and the secondary BSS list in the locally saved device related information is updated by using the secondary BSS list in the new device related information.

In this way, since the user equipment acquires the primary BSS and the secondary BSS allocated by the AP device, each BSS is an independent communication system, and when data is transmitted in the primary BSS and the secondary BSS, even if there is a BSS The spectrum resource is occupied by other devices, and the BSS and the other BSSs in the secondary BSS can continue to perform data transmission, thereby improving data transmission efficiency of the user equipment.

Further, before determining, in step 101, whether the user equipment supports BSS aggregation, the user equipment may acquire a beacon frame on each BSS, and detect a BSS according to the BSS information in the beacon frame; or send a probe to each BSS. The request detects the BSS based on the received probe response frame. If the BSS information in the beacon frame includes the BSS aggregation indication, determining that the detected BSS supports the BSS aggregation; where the BSS aggregation indication is used to indicate that the BSS managed by the AP device supports the BSS aggregation. Further, the beacon frame may further include power constraint information or the probe response frame further includes power constraint information, and the user equipment may further acquire a local maximum transmit power of the user equipment according to the power constraint information, where the power is The constraint information records the power constraint value, and the user equipment may obtain the rated maximum transmit power of the user equipment, and the difference between the rated maximum transmit power and the power constraint value to obtain the local maximum transmit power; Legal maximum transmit power; maximum local transmit power And selecting the smallest transmitting device power among the legal maximum transmitting powers as the actual maximum transmitting power of the user equipment. Thus, in the subsequent data transmission process, the transmit power of the normal operation of the transmitter of the user equipment needs to be less than or equal to the actual maximum transmit power of the user equipment, which can reduce the noise generated during the data transmission. The process of acquiring the actual maximum transmit power of the user equipment may be referred to as a TPC (Transmission Power Control) process. It should be noted that after the acquiring the AP device is allocated to the primary BSS and the secondary BS S of the user equipment, the user equipment may also receive multiple managements of the AP device, such as authentication, association, and privacy. Management (secretity), transition, and DFS (Dynamic Frequency Selection).

When the AP device performs authentication management, the user equipment may first generate an authentication request. Then, the authentication request is sent to the AP device in the primary BSS, so that the AP device generates the authentication response information according to the authentication request. Finally, the primary BS S receives the authentication response information sent by the AP device.

When the AP device performs association management, the user equipment may first generate an association request. Then, the association request is sent to the AP device in the primary BSS, so that the AP device generates association response information according to the association request. Finally, the association response information sent by the AP device is received by the primary BS S.

When the AP device performs re-association management, the user equipment may first generate a re-association request; then, send the re-association request to the AP device in the primary BSS, so that the AP device according to the re-association request Generating re-association response information; finally, receiving, at the primary BSS, the re-association response information sent by the AP device.

When the AP device performs deauthentication management, the user equipment may first generate a deauthentication request; then, send the deauthentication request to the AP device in the primary BSS, so that the AP device is configured according to the deauthentication request. Generating de-authentication response information; finally, receiving, at the primary BSS, the release sent by the AP device Authentication response information.

When the AP device performs disassociation management, the user equipment may first generate a disassociation request; then, send the disassociation request to the AP device in the primary BSS, so that the AP device generates according to the association request. De-releasing the response information; finally, receiving, in the primary BSS, the disassociation response information sent by the AP device.

When the AP device performs the DFS management, the user equipment may first receive the measurement request information sent by the AP device, where the measurement request information includes the silent period; and then measure the channel list supported by the user equipment in the silent period. Whether there is a radar signal; finally, sending measurement response information to the AP device, the measurement response information indicating whether a radar signal exists in a channel list supported by the user equipment; and when the measurement response information indicates a channel list supported by the user equipment There is a radar signal in which a channel switching statement sent by the AP device is obtained.

The user equipment can also actively perform DF S management. For example, the user equipment can obtain a silent time period. In the silent time period, it is measured whether there is a radar signal in the channel list of the user equipment, and the channel list records the current An available channel of the user equipment; when there is a radar signal in the channel list of the user equipment, the association with the channel in which the radar signal is present is released. The embodiment of the present invention provides a spectrum resource management method, which is applied to an AP device. As shown in FIG. 2, the method includes:

Step 201: Divide the spectrum resource managed by the AP device into at least two member carriers.

For example, the AP device may scan the first k channels of the frequency ridge resource managed by the AP device, where k is an integer greater than 1. determining whether the sum of the bandwidths of the first k channels is greater than that of the AP device. If the sum of the bandwidths of the first k channels is greater than the maximum supported bandwidth of the AP device, all available channels in the first k channels are obtained, and the available channels are divided into at least two component carriers. .

Step 202: Establish a BSS for each of the component carriers. Step 203: Assign one or more of the BSSs to the user equipment.

The user equipment can perform data transmission in the spectrum resource allocated by the AP device, and can transmit data with other user equipments, and can also transmit data with the AP device, which is not limited by the present invention.

In this way, since the AP device divides the spectrum resources managed by the AP device into at least two component carriers, and establishes a basic service set BSS for each of the component carriers, the final AP device establishes at least two BSSs, even if The spectrum resources in which any one BSS is located are occupied by other devices, and other BSSs managed by the device can be unaffected and data transmission is continued, thereby improving the data transmission efficiency on the spectrum resources managed by the device.

Further, after step 202, the method further includes:

Broadcasting a beacon frame, the beacon frame includes BSS information, so that the user equipment performs BSS detection according to the BSS information; or, the probe request frame is responded to the probe response frame for each user equipment, where the probe response frame includes Describe the BSS information.

For example, the BSS information may include a BSS aggregation indication, where the BSS aggregation indication is used to indicate that the BSS managed by the device supports BSS aggregation. It should be noted that the BSS managed by the device includes at least the BSS established by the device. . The BSS information may also include BSS classification information and/or BSS aggregation list. The BSS classification information is used to indicate the category of the BSS established by the AP device, and the BSS aggregation list records the identity of the BSS established by the AP device. The user equipment may determine whether the BSS supports carrier aggregation by determining whether the obtained BSS information includes a BSS aggregation indication. When the acquired BSS information includes a BSS aggregation indication, the BSS is determined to support carrier aggregation; and the acquired BSS information does not include the BSS aggregation. If indicated, it is determined that the BSS does not support carrier aggregation.

Optionally, the beacon frame may further include power constraint information; or, the probe response frame further includes power constraint information, so that the user equipment may obtain the local maximum of the user equipment according to the power constraint information. Transmit power, the power constraint information records a power constraint value, and the user equipment can obtain the rated maximum transmit power of the user equipment, and the difference between the rated maximum transmit power and the power constraint value is obtained. The local maximum transmit power; obtaining a legal maximum transmit power of the user equipment; selecting a minimum transmit device power as the actual maximum transmit power of the user equipment in the local maximum transmit power and the legal maximum transmit power. Thus, in the subsequent data transmission process, the transmit power of the normal operation of the transmitter of the user equipment needs to be less than or equal to the actual maximum transmit power of the user equipment, which can reduce the noise generated during the data transmission. The process of obtaining the actual maximum transmit power of the user equipment may be referred to as a TPC (Transmission Power Control) process.

It should be noted that, after establishing the BSS for each of the component carriers, the AP device may further add a BSS to the spectrum resource managed by the AP device; and/or delete the spectrum resource managed by the AP device. BS S. In this way, reconfiguration management such as adding or deleting BSS can be implemented. The allocated BSS of the AP device to each user equipment can be flexibly adjusted, which improves the flexibility of BS S management.

For example, when the BSS needs to be added to the spectrum resource managed by the AP device, the AP device may acquire an unused channel of the spectrum resource managed by the AP device; scan the nth channel in the unused channel, n is an integer greater than or equal to 1; determining whether the channel is available; if the channel is available, determining whether a sum of bandwidths of the used channel and the scanned first n channels is greater than a maximum supported bandwidth of the AP device; The sum of the used channel and the bandwidth of the first n channels is greater than the maximum supported bandwidth of the AP device, and the first n-1 available channels are divided to obtain at least one component carrier, and a BSS is established for each of the component carriers respectively. Add the BSS to the BSS aggregation list.

When the BSS needs to be deleted in the spectrum resource managed by the AP device, the AP device may acquire the used channel of the spectrum resource managed by the AP device; measure the mth channel in the used channel, where the m is greater than Or an integer equal to 1; determining whether the channel is available; if the channel is unavailable, deleting the BSS on the channel, deleting the BS S in the BSS aggregation list.

After the BSS is added to the spectrum resource managed by the AP device, and/or after the BS S is deleted in the spectrum resource managed by the AP device, the AP device performs the BSS addition or deletion, and the corresponding AP device manages The device related information of the user equipment is changed.

In particular, the BSS in the BSS list may be from a BSS constructed in different situations. For example, the secondary BSS allocated by the AP device to the first user equipment is a BSS managed by the AP device; and/or The secondary BSS allocated by the AP device to the first user equipment is a BSS managed by another AP device; and/or the AP device is the The secondary BSS allocated by the first user equipment is a BSS established by at least two user equipments, where the at least two user equipments may include the first user equipment or may not include the first user equipment.

It should be noted that, the silent time period is a radar signal measurement time period, in which, in addition to the channel test, the device that measures the radar signal stops transmitting data in the channel that needs to be measured. . For example, when the AP device measures whether there is a radar signal in the channel list of the AP device during the silent period, the corresponding user equipment stops data transmission in the channel in the channel list of the AP device.

In particular, the AP device can also obtain the maximum rated transmit power of each user equipment; the maximum transmit power is selected as the maximum transmit power of the AP device in the rated maximum transmit power of each user equipment, so that the subsequent data is During transmission, the transmit power of the normal operation of the transmitter of the AP device needs to be less than or equal to the maximum transmit power of the AP device, which can reduce the noise generated during data transmission. The embodiment of the present invention provides a data transmission method. As a plurality of user equipments may exist in the communication system, the first user equipment is taken as an example in this embodiment. As shown in FIG. 3, the method includes:

Step 301: The AP device divides the spectrum resource managed by the AP device into at least two component carriers.

Specifically, the AP device can perform the following steps: Al. Scanning the kth channel of the spectrum resource managed by the AP device, the k being an integer greater than one. Perform step bl.

Bl. Determine if the kth channel is available. When the channel is available, step c1 is performed, and when the channel is not available, step dl is performed.

Cl. Determine whether the sum of the bandwidths of the first k channels is greater than the maximum supported bandwidth of the AP device. When the sum of the bandwidths of the first k channels is not greater than the maximum supported bandwidth of the AP device, step dl is performed. When the sum of the bandwidths of the first k channels is greater than the maximum supported bandwidth of the AP device, step el is performed.

Dl. Get a new k for k+1 and repeat steps al to dl until all channels have been scanned. Perform step el.

El. Obtain all available channels in the channel whose sum of the bandwidths of the first k channels is greater than the maximum supported bandwidth of the AP device, and divide the channel into at least two component carriers.

The determination of whether the sum of the bandwidths of the first k channels is greater than the maximum supported bandwidth of the AP device is based on the bandwidth carrying capacity of the AP device. Generally, the maximum supported bandwidth of the BSS needs to be established on the AP device. Inside.

Specifically, in step 301, after all channel scans of the spectrum resources managed by the AP device are completed, the sum of the bandwidths of the first k channels is still less than or equal to the maximum supported bandwidth of the AP device, and the bandwidth of the first k channels is divided. Is at least one member carrier. In practical applications, the bandwidth of the channel is typically 20 MHz. It should be noted that, in the step el, there may be independent available channels, because there may be multiple adjacent available channels among all available channels in the channel of the first k channels that are larger than the maximum supported bandwidth of the AP device. a channel, where the independent channel indicates that the adjacent channels of the available channel are all unavailable channels, the process of dividing the channel into at least two component carriers may include: placing two or more adjacent ones of the channels The channels are divided into one component carrier, and one channel is divided into one component carrier.

It should be noted that the sequence of the steps of the method for dividing the frequency band resource provided by the embodiment of the present invention may be appropriately adjusted. For example, the sequence of the steps bl and cl may be reversed, and the steps may also be increased or decreased according to the situation, and any familiar technical field. The skilled person can easily think of the method of variation within the scope of the technology disclosed by the present invention and should cover It is within the scope of the present invention and therefore will not be described again.

Step 302: The AP device establishes a BSS for each of the component carriers.

The AP device can establish a BSS for each of the component carriers, and the process of establishing the BSS can refer to the prior art.

After the BSS is established, the beacon frame may be broadcasted, and the beacon frame includes BSS information, so that the user equipment performs BSS detection according to the BSS information. The BSS information may further include a BSS aggregation indication, where the BSS aggregation indication is used to indicate that the BSS managed by the AP device supports BSS aggregation. The BSS information may also include BSS classification information and/or a BSS aggregation list. The BSS classification information is used to indicate the category of the BSS established by the AP device, and the BSS aggregation list records the ID (IDentity, ID) of the BSS established by the AP device. In particular, the specific form of the BSS classification information and/or the BSS aggregation list may be various. For example, the BSS aggregation list and the BSS category may be in the same table, as shown in FIG. 4, the table of FIG. 4 records the BSS. The aggregation list 10 and the BSS classification information 20, the BSS aggregation list 10 records the ID numbers of the BSS, namely ID 1, ID 2, ID 3, ID 4, and ID 5, and the BSS classification information 20 records the category of each BSS, and the ID 1 is the first category. ID2 is the first class, ID3 is the second class, ID4 is the second class, and ID5 is the first class. In particular, a BSS aggregation list may also be established for BSSs belonging to the same category, and the BSS information includes multiple BSS aggregation lists.

In this way, each user equipment can obtain related information of the AP device according to the beacon frame, and obtain BSS information according to the BSS information in the beacon frame to perform BSS detection.

In particular, the AP device may also respond to the probe request frame for the probe request frame of each user equipment, where the probe response frame includes the BSS information. For the BSS information, reference may be made to the BSS information in the above-mentioned beacon frame, which is not described in this embodiment.

Step 303: The first user equipment establishes a connection with the AP device.

The first user equipment first needs to detect the BSS in the communication system. For example, the first user equipment can detect multiple BSSs at the same time, or can detect the BSSs in the communication system one by one. The detection process may include two methods: active detection and passive detection. The passive detection may be that the first user equipment acquires a beacon frame on each BSS, and detects the BSS according to the BSS information in the beacon frame; since each AP device is in the week The beacon frame is broadcast periodically, and each beacon frame includes only one BSS information. The first user equipment can acquire the beacon frame one by one, or can obtain multiple beacon frames at the same time. The active detection may be that the first user equipment sends a probe request to each BSS, and the probe request is sent to the corresponding AP device by each of the BSSs, and then the AP device may return a probe response frame, and then the first user equipment according to the received A BSS is detected by detecting a response frame, wherein the probe response frame includes the BSS information.

When the first user equipment detects a BSS, the first user equipment first determines whether the detected BSS supports the BSS aggregation. Optionally, the first user equipment may determine whether the BSS is determined by determining whether the acquired BSS information includes a BSS aggregation indication. Supporting carrier aggregation, determining that the BSS supports carrier aggregation when the obtained BSS information includes a BSS aggregation indication, and determining that the BSS does not support carrier aggregation when the acquired BSS information does not include the BSS aggregation indication; and the first user equipment needs to determine the location Whether the first user equipment supports BSS aggregation; when the detected BSS supports BSS aggregation and the first user equipment supports BSS aggregation, to the AP device that manages the detected BSS in the detected BSS Sending the request information, so as to obtain the primary BSS and the secondary BSS allocated by the AP device to the user equipment after establishing a connection with the AP device. In particular, when the detected BSS does not support the BSS aggregation or the first user equipment does not support the BSS aggregation, the first user equipment continues to detect other BSSs and performs the foregoing determination process, which is not described herein.

This embodiment assumes that the detected BSS is the first BSS, and the detected BSS is the BSS established by the AP device. The request information is transmitted by the first BSS, and after receiving the request information sent by the first user equipment, the AP device sets the first BSS as the primary BSS of the first user equipment according to the request information, to The AP device is configured to establish a connection with the first user equipment by using the primary BSS, and then the AP device can allocate a primary BSS and a secondary BSS to the user equipment on the primary BSS, where the AP device is located. The primary BSS allocated to the user equipment on the primary BSS may be the same as the current primary BSS, or may be different from the current primary BSS. At different times, the user equipment needs to switch to the new primary BSS.

Step 304: The AP device allocates a primary BSS and a secondary BSS to the first user equipment. It is assumed that the first user equipment is any one of the user equipments managed by the AP device, and the first user equipment supports BSS aggregation. When the first user equipment establishes a connection with the AP device, the current primary BSS is the first A BSS, as shown in FIG. 5, the process for the AP device to allocate the primary BSS and the secondary BSS to the first user equipment includes: Step 3041: The AP device acquires a BSS aggregation list of the current primary BSS.

When the first user equipment establishes a connection with the AP device in step 303, the first user equipment obtains the BSS information by acquiring the beacon frame or the probe response frame, and sets the ―BSS as the primary BSS, which is currently in this embodiment. The primary BSS is the first BSS. Since the BSS information further includes the BSS aggregation list of the first BSS, the first user equipment can locally save the BSS aggregation list of the current primary BSS.

Optionally, the user equipment may also receive a BSS aggregation list of the current primary BSS sent by the AP device.

Step 3042: The first user equipment acquires BSS measurement information, where the BSS measurement information records a measurement rule.

The BSS measurement information may be information that is sent by the AP device, where the BSS measurement information indicates that all or part of the BSS in the BSS aggregation list is the BSS to be tested; the BSS measurement information may also be a pre-stored pre-stored by the first user equipment. The information measurement rule is set, according to the information measurement rule, the first user equipment may filter all or part of the BSS from the BSS aggregation list as the BSS to be tested.

Step 3043: The first user equipment measures the to-be-measured BSS according to the BSS measurement information.

The channel quality measurement process is the same as the prior art, and the present invention will not be described again. Step 3044: The first user equipment sends, in the primary BSS, the measured channel quality of the BSS to be measured to the AP device, and the carrier aggregation capability that the first user equipment can support.

Specifically, before step 3044, the user equipment may compare the measured channel quality of the BSS to be measured to obtain the first d BSS to be measured with good channel quality, and then return the channel quality to the AP device in step 3044. Returning only the channel quality of the first d BSS to be measured, which can reduce the computational complexity of the AP device and simplify In the process, the d is a preset value, and the d is an integer greater than or equal to 1.

Step 3045: The AP device generates a primary BSS indication and a secondary BSS list of the first user equipment according to the channel quality of the BSS to be measured and the carrier aggregation capability supported by the first user equipment.

The secondary BSS list includes at least one secondary BSS indication, and the primary BSS indicates a primary BSS that is used to indicate that the user equipment needs to be connected, and the secondary BSS indicates a secondary BSS that is used to indicate that the user equipment needs to be connected.

The AP device allocates one or more of the BSSs established by the AP device to the user equipment, where the primary BSS is included, and the secondary BSS may be established by the AP device, or may be established by other AP devices. Therefore, the BSS is configured. The BSS in the list may be from a BSS constructed in different situations, for example, the secondary BSS allocated by the AP device to the first user equipment is a BSS managed by the AP device; and/or the AP device is the The secondary BSS allocated by the first user equipment is a BSS managed by another AP device; and/or the secondary BSS allocated by the AP device to the first user equipment is a BSS established by at least two user equipments, where The at least two user equipments may include the local user equipment or the local user equipment, which is not limited by the present invention.

As shown in FIG. 6, it is assumed that the AP device is an AP device N, and the current primary BSS of the first user device is a BSS established by the AP device, but in step 3042, the first user device measures that another AP device exists. The BSS1 channel of the M is of good quality. After step 3043, the AP device N receives the measurement information of the BSS1, and can exchange the BSS information of the BSS1 with the AP device M through a certain negotiation mechanism, so that the AP device can establish the AP device M. The BSS1 serves as a secondary BSS of the first user equipment to provide services. In this embodiment, the AP device N needs to put the BSS information of the BSS1 of the AP device M into the secondary BSS list of the first user equipment.

Step 3046: The AP device sends the device related information of the first user equipment to the first user equipment, where the device related information of the first user equipment includes a primary BSS indication and a secondary BSS list of the first user equipment.

Specifically, after the AP device sends the device related information of the first user equipment to the first user equipment, the AP device needs to locally save the first user equipment in the AP device. Device-related information. The initial configuration of the user equipment is completed by the AP device. The configuration process can be implemented on the primary BSS of the first user equipment.

Step 305: The AP device manages the BSS established by the AP device.

It should be noted that, after establishing a basic service set BSS for each of the component carriers, the AP device may further add a BSS to the spectrum resource managed by the AP device; and/or a spectrum managed by the AP device. Remove the BSS from the resource. In this way, reconfiguration management such as adding or deleting BSS can be implemented. The BSS allocated by the AP device to each user equipment can be flexibly adjusted, which improves the flexibility of BSS management.

For example, when the BSS needs to be added to the spectrum resource managed by the AP device, the AP device may acquire an unused channel of the spectrum resource managed by the AP device; scan the nth channel in the unused channel, n is an integer greater than or equal to 1; determining whether the channel is available; if the channel is available, determining whether a sum of bandwidths of the used channel and the scanned first n channels is greater than a maximum supported bandwidth of the AP device; If the sum of the used channel and the bandwidth of the first n channels is greater than the maximum supported bandwidth of the AP device, the first n-1 available channels are divided to obtain at least one component carrier, and a BSS is established for each of the component carriers. Add the BSS to the BSS aggregation list.

For example, adding a BSS to the spectrum resource managed by the AP device includes: a2. Obtaining an unused channel of the spectrum resource managed by the AP device, and performing step b2.

B2. Scan the nth channel in the unused channel, where n is an integer greater than or equal to 1, and perform step c2.

C2. Determine whether the nth channel is available, when the channel is available, perform step d2, and when the channel is unavailable, perform step f2.

Determining whether the sum of the bandwidth of the used channel and the scanned first n channels is greater than the maximum supported bandwidth of the AP device, when the sum of the bandwidth of the used channel and the scanned first n channels is not greater than the AP device The maximum supported bandwidth is performed. In step f2, when the sum of the bandwidth of the used channel and the scanned first n channels is greater than the maximum supported bandwidth of the AP device, step e2 is performed.

E2. The first n-1 available channels are divided to obtain at least one component carrier, respectively Each of the component carriers establishes a BSS, adds the BSS to the BSS aggregation list, and performs step f2.

F2. Let n+1 get a new n, repeat steps a2 to f2 until all channels in the unused channel are scanned.

Specifically, in step f2, after all channel scans of the spectrum resources managed by the AP device are completed, the sum of the bandwidths of all channels in the unused channel is still less than or equal to the maximum supported bandwidth of the AP device, and then the bandwidth of all channels is used. Divided into at least one component carrier. In practical applications, the bandwidth of the channel is typically 20 MHz. It should be noted that, in step e2, there may be independent, because there may be multiple adjacent available channels among all available channels in the channel of the first n-1 channels that are larger than the maximum supported bandwidth of the AP device. The available channel, where the independent channel indicates that the adjacent channel of the available channel is an unavailable channel, the process of dividing the channel into at least two component carriers may include: placing two adjacent ones of the channels Or multiple channels are divided into one component carrier, and one channel is divided into one component carrier.

It should be noted that the sequence of the method steps for adding the BSS provided by the embodiment of the present invention may be appropriately adjusted. For example, the sequence of the steps c2 and d2 may be reversed, and the steps may be correspondingly increased or decreased according to the situation, and any familiar technical field. Those skilled in the art can easily conceivably change the method within the scope of the present invention, and are not included in the scope of the present invention.

When the BSS needs to be deleted in the spectrum resource managed by the AP device, the AP device may acquire the used channel of the spectrum resource managed by the AP device; measure the mth channel in the used channel, where the m is greater than Or an integer equal to 1; determining whether the channel is available; if the channel is not available, deleting the BSS on the channel, deleting the BSS in the BSS aggregation list.

For example, deleting the BSS in the spectrum resource managed by the AP device includes: a3. Obtaining the used channel of the spectrum resource managed by the AP device, and performing step b3.

B3. Measure the mth channel in the used channel, where m is an integer greater than 1, and perform step c3. C3. Determine whether the mth channel is available. If the channel is unavailable, perform step d3. If the channel is available, perform step e3.

D3. Deleting the BSS on the mth channel, deleting the BSS in the BSS aggregation list, and obtaining a new m from m+1, repeating steps a3 to d3 until all channels in the used channel are scanned .

E3. Get m+1 to get a new m, repeat steps a3 to e3 until all channels in the used channel are scanned.

It should be noted that the sequence of the method for deleting the BSS provided by the embodiment of the present invention may be appropriately adjusted. For example, the sequence of steps d3 and e3 may be reversed, and the steps may be correspondingly increased or decreased according to the situation, and any familiar technical field. Those skilled in the art can easily conceivably change the method within the scope of the present invention, and are not included in the scope of the present invention.

Step 306: The AP device performs configuration management on the first user equipment in the primary BSS of the first user equipment.

In step 305, the AP device adjusts the BSS aggregation list, where the adjusted BSS may be the primary BSS or the secondary BSS originally allocated for the first user equipment. Therefore, in the embodiment of the present invention, the first user equipment is used as an example, the AP device may generate device-related information of the first user equipment, and send the device to the first user equipment in the primary BSS of the first user equipment. Corresponding information, so that the first user equipment compares the device related information locally saved by the first user equipment with the device related information received by the first user equipment, and reconfigures the first user according to the comparison result. Device-related information local to the device. Specifically, the first user equipment may receive the device related information that is sent by the AP device in the primary BSS, because the first user equipment is previously connected to the AP device, therefore, in step 3046, the first user equipment The information about the device delivered by the AP device has been received and saved locally. Therefore, the device-related information sent by the AP device is new device-related information for the first user device. The first user device can Comparing the locally saved device related information with the new device related information; if the primary BSS indication in the locally saved device related information is different from the primary BSS indication in the new device related information, the first use is The user equipment is switched to the primary BSS indicated by the primary BSS indication in the new device related information; if the secondary BSS list in the locally saved device related information and the secondary BSS list in the new device related information Differently, the secondary BSS list in the locally saved device related information is updated with the secondary BSS list in the new device related information.

It should be noted that the AP device may also perform authentication, association, security, handover, TPC, and DFS management on the first user equipment in the primary BSS of the first user equipment.

For example, when the AP device performs authentication management on the first user equipment in the primary BSS of the first user equipment, the first user equipment may first generate an authentication request, and then send the AP to the AP in the primary BSS. After the device sends the authentication request, the AP device generates the authentication response information according to the authentication request after receiving the authentication request sent by the first user equipment in the primary BSS, and then the first The user equipment sends the authentication response information.

The BSS receives the authentication response information sent by the first device.

When the AP device performs association management on the first user equipment in the primary BSS of the first user equipment, the first user equipment may first generate an association request, and then send the location to the AP device in the primary BSS. After the association request receives the association request sent by the first user equipment in the primary BSS, the AP device generates association response information according to the association request, and then sends the primary BSS to the first user equipment. The association response information.

When the AP device performs re-association management on the first user equipment in the primary BSS of the first user equipment, the first user equipment may first generate a re-association request, and then in the primary BSS to the AP device. Sending the re-association request, after receiving the re-association request sent by the first user equipment in the primary BSS, the AP device generates re-association response information according to the association request; and then in the main BSS The first user equipment sends the re-association response information.

After the de-authentication request sent by the user equipment, the de-authentication response information is generated according to the de-authentication request; and then the de-authentication response information is sent to the first user equipment by the primary BSS. In particular, the AP device may also first generate a de-authentication request, and then send the de-authentication request to the first user equipment in the primary BSS, where the first user equipment receives the AP device in the primary BSS. After the transmitted de-authentication request, the de-authentication response information is generated according to the de-authentication request; and then the de-authentication response information is transmitted to the AP device by the primary BSS.

When the AP device performs disassociation management on the first user equipment in the primary BSS of the first user equipment, the first user equipment may first generate a disassociation request, and then in the main BSS to the AP device.

In particular, the AP device may also first generate a disassociation request, and then send the disassociation request to the first user equipment in the primary BSS, where the first user equipment receives the AP device in the primary BSS. After the disconnection request is transmitted, the disassociation response information is generated according to the disassociation request; and then the disassociation response information is transmitted to the AP device by the main BSS.
