Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

It is noted that, in this document, relational terms such as "first" and "second," and the like, may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions.

In a first aspect, as shown in fig. 1, this embodiment provides a method for wireless local area network communication, which is applied to an Access Point (AP), and the method may include the following steps 101 and 102:

101. generating a message frame, wherein the message frame carries a corresponding relation between a characteristic value of a basic service set (PLCP) (physical layer conversion Protocol) Data Unit (PLCP Protocol Data Unit) and a communication frequency band; the corresponding relation comprises at least one basic service set PPDU characteristic value, and each basic service set PPDU characteristic value corresponds to one communication frequency band.

102. And sending the message frame to Stations (Stations, STA).

In this embodiment, the characteristic value of the basic service set PPDU is a basic service set color value (BSS) (basic service set) color), and the purpose of the characteristic value is to enable a station that does not receive the PPDU to discard the remaining PPDU, so that the station saves power and reduces the occurrence of communication collisions inside the BSS. The AP communicates with the STA at 2.4GHz or other frequency bands, and the BSS color values are different.

In this embodiment, the correspondence does not include the communication frequency band for sending the message frame and the BSS color value corresponding to the communication frequency band. For example, if the communication frequency band for sending the message frame is 2.4GHz and the corresponding BSS color value is 6, the BSS color value carried in the correspondence is 9, the corresponding communication frequency band is 5.8GHz, and the BSS color value is not 6 and the corresponding communication frequency band is 2.4 GHz.

In this embodiment, in order to coordinate a plurality of communication channels used by the AP, a correspondence relationship between a value of the BSS color and a communication frequency band may be configured. The value of the BSS color corresponds to the communication frequency band one by one. And the AP sends the corresponding relation to the STA to complete the configuration of the value of the BSS color.

In this embodiment, the manner in which the AP sends the correspondence to the STA is that the AP sends a message frame carrying the correspondence to the STA. The message frame may be a Beacon (Beacon) frame, a Probe Response (Probe Response) frame, an Association Response (Association Response) frame, or an Authentication Response (Authentication Response) frame.

In this embodiment, the AP may determine the timing for sending the corresponding relationship by selecting different message frames. There are two ways, active and passive, for the STA and AP to establish the initial connection, and the process of establishing the initial connection continues to use the prior art, which is not described in this embodiment.

In this embodiment, when the STA actively establishes the initial connection with the AP, after receiving a Probe Request (Probe Request) frame or an Association Request (Association Request) frame sent by the STA, the AP may carry the correspondence in a Probe Response (Probe Response) frame or an Association Response (Association Response) frame fed back to the STA.

In this embodiment, when the STA establishes an initial connection with the AP passively, the AP may carry the correspondence in a Beacon (Beacon) frame and broadcast the Beacon (Beacon) frame.

In this embodiment, the manner in which the message frame carries the corresponding relationship specifically includes: the message frame carries an IE (Information Element) in a specific format:

frequency band 1

Color value of frequency band 1

Frequency band 2

Color value of frequency band 2

……

Frequency band N

Color value of frequency band N

The frequency bands 1 to N indicate that the corresponding relationship includes N communication frequency bands, where N is a positive integer greater than 2, and each frequency band corresponds to a value of a BSS color.

In this embodiment, the correspondence carried by the message frame may not include a communication frequency band when the STA and the AP perform initial connection establishment and a value of a BSS color corresponding to the communication frequency band.

In this embodiment, when the AP communicates with the STA, the AP may determine the communication frequency band according to the BSScolor value carried in the physical frame header of the received communication frame.

It can be seen that, in this embodiment, the access point carries the corresponding relationship between the PPDU feature value of the basic service set and the communication frequency band in the message frame, and sends the message frame to the station, so that the configuration of the PPDU feature value of the basic service set is implemented, so that the access point and the station can communicate through different communication frequency bands, and the throughput of the wireless local area network is improved.

In some embodiments, the correspondence includes:

In this embodiment, the correspondence relationship includes three communication frequency bands. When the AP communicates with the STA, the AP may determine a communication frequency band according to a basic service set PPDU characteristic value carried in a physical frame header of a received communication frame. For example, if the characteristic value of the basic service set PPDU is the second value, it is determined that the corresponding communication frequency band is 5 GHz.

In some embodiments, the correspondence includes:

In this embodiment, the correspondence relationship includes two communication frequency bands. When the AP communicates with the STA, the AP may determine a communication frequency band according to a basic service set PPDU characteristic value carried in a physical frame header of a received communication frame. For example, if the characteristic value of the basic service set PPDU is the fourth value, it is determined that the corresponding communication frequency band is 45 GHz.

In practical application, the corresponding relationship may include five communication frequency bands, which respectively correspond to the first value to the fifth value of the PPDU characteristic value of the basic service set. The correspondence may further include: the characteristic value of the basic service set PPDU is a sixth value, and the communication frequency band corresponding to the sixth value is 5.8 GHz.

Those skilled in the art will appreciate that different basic service set PPDU characteristic values may be set for different communication frequency bands.

In some embodiments, the correspondence may further include: a basic service Set identification bssid (basic service Set identifier) value.

In this embodiment, the PPDU feature value and the communication frequency band of the basic service set in the correspondence both correspond to the BSSID value of the basic service set identifier.

BSSID value

Frequency band 1

Color value of frequency band 1

BSSID value

Frequency band 2

Color value of frequency band 2

……

In this embodiment, the number of frequency bands included in the format is determined based on the number of communication frequency bands included in the correspondence relationship. All basic service set PPDU characteristic values and all communication frequency bands included in the corresponding relation correspond to the same BSSID value.

In some embodiments, the correspondence may further include: at least one basic service set identifies BSSID values.

In this embodiment, the PPDU characteristic value of the basic service set, the communication frequency band, and the BSSID value of the basic service set are in one-to-one correspondence.

BSSID value 1

Frequency band 1

Color value of frequency band 1

BSSID value of 2

Frequency band 2

Color value of frequency band 2

……

In this embodiment, the number of frequency bands included in the format is determined based on the number of communication frequency bands included in the correspondence relationship. The basic service set PPDU characteristic value and the communication frequency band included in the corresponding relation correspond to the BSSID value one by one. The AP corresponds to different BSSID values in different communication bands.

In practical application, the number of BSSID values may be less than the number of communication bands, the same BSSID value may correspond to different communication bands, and any communication band may only correspond to one BSSID value.

In some embodiments, the method of wireless local area network communication may include the following steps 103 to 105 in addition to the method steps shown in fig. 1:

103. and after detecting that an access point exists in the coverage range of the current communication frequency band, adjusting the characteristic value of a basic service set PPDU corresponding to the current communication frequency band.

104. And generating a message frame, wherein the message frame carries the current communication frequency band and the adjusted characteristic value of the basic service set PPDU.

105. And sending the message frame to the station.

In this embodiment, the manner for the AP to detect that the AP exists in the coverage area of the current communication frequency band is, for example: the AP receives Beacon (Beacon) frames broadcast by other APs.

In this embodiment, the AP adjusts the PPDU characteristic value of the basic service set corresponding to the current communication frequency band until no other AP exists in the coverage of the AP.

In this embodiment, the message frame may be the same as or different from the message frame shown in fig. 1.

In this embodiment, a plurality of communication bands or one BSSID at different times correspond to a plurality of BSS color values in the same communication band.
