Problems solved by technology

Although 802.11ax and previous WiFi in the same working frequency band are configured with multiple links, generally speaking, each multi-link establishes a different Basic Service Set (BSS), and only one link can communicate with the link at a time. Site communication within the homed BSS

example 2

[0247] Optionally, the first information field may be set in a BSS parameter (BSS parameter) field or a TBTT information field of the simplified neighbor report element. In FIG. 8( a ), it is specifically illustrated by taking that the Co-MLD field is a reserved (reserved) bit (bit 7) of the BSS parameter (BSS parameter) field as an example. As shown in Figure 8(a), in Example 1, if the reported AP and the reporting AP are in the same MLD or the members of the reported AP and the MLD to which the reporting AP belong belong to the same MultipleBSSID set, the Co-MLD field in the The value of an indicator bit is set to 1; if the reported AP and the reporting AP are not in the same MLD and the reported AP does not belong to the same Multiple BSSID set as the members of the MLD to which the reporting AP belongs, then the value of this indicator bit is set to 0. Example 2, whether the reported AP is in the same MLD as the reporting AP can be indicated by an indicator bit, for exampl...

example 1

[0302] Example 1: The seventh information is carried in a specific field (for example, it may be called a "complete field"), and the specific field is used to indicate whether the reporting AP carries the information of all the first reported APs in the management frame, and the information of all the first reported APs. The member information in the Multiple BSSID set where the AP is reported, for example, if yes, the seventh information may specifically take a value, such as 1, and if not, the seventh information may specifically take another value, such as 0.

[0303] After obtaining the seventh information, the receiving end may know whether the relevant information corresponding to each reported AP has been completely received.

[0304] Example 2: the seventh information is carried in a specific field (for example, it may be called a "complete field"), and the specific field is used to indicate how many information cycles the reporting AP needs to report all the informatio...

[0338] Example 1: The station carries the MLD-index and one or more items of one or more link IDs in the probe request frame, so as to request the AP to reply the information of the AP corresponding to the one or more link IDs in the probe response frame. Then the station establishes an association with one or more APs according to the information of the APs corresponding to the one or more Link IDs. For example, if Image 6 As shown, the MLD-index carried in the probe request is MLD2, and the carried link ID is link 2 (link2), then the AP can determine that the corresponding AP is the AP whose MAC address is BSSID-2x according to MLD2 and link2, so Send more detailed information about the AP whose MAC address is BSSID-2x to the station, and the station establishes an association with the AP whose MAC address is BSSID-2x.

[0339] Example 2: The station carries the MLD-index and one or more link IDs in the probe request frame, so as to request the AP to reply to the AP inform...

Abstract

Provided in an embodiment of the present application are an access point (AP) multi-link equipment discovery method and a related device, for example, applied to a WLAN supporting 802.11 be, the method comprising: a report AP sends a first management frame to a station, the first management frame carrying information of a neighbor AP, the report AP belonging to AP multi-link equipment, the reported AP indicated by the neighbor AP information and the report AP belonging to the same multi-link equipment or the reported AP indicated by the neighbor AP information and other APs in the multi-link equipment where the report AP is located belonging to the same multi-BSSID set. Therefore, the station receiving the first management frame can know the MLD structure and the multi-BSSID set structure on the AP multi-link equipment, so that the station can better select a proper AP for association.

Description

technical field [0001] The present application relates to the field of communication technology, and in particular to a node AP multi-link device discovery method and related devices. Background technique [0002] In order to greatly increase the service transmission rate of the WLAN system, the Institute of Electrical and Electronics Engineers (Institute of Electrical and Electronics Engineers, IEEE) 802.11ax standard is based on the existing Orthogonal Frequency Division Multiplexing (OFDM) technology. Orthogonal Frequency Division Multiple Access (OFDMA) technology is adopted. OFDMA technology supports multiple nodes to transmit and receive data simultaneously, thereby achieving multi-site diversity gain. In 2017 when 802.11ax was finalized, the Federal Communications Commission (FCC) of the United States opened a new free frequency band 5925-7125MHz, hereinafter referred to as 6GHz. So the 802.11ax standard workers extended the working range of 802.11ax devices from 2....
