Description

Technical Field

[0001] The present disclosure relates to the field of wireless communications, and more specifically, to a communication method and a communication device under multiple connections. Background Art

[0002] The current research scope of Wi-Fi technology includes: 320MHz bandwidth transmission, aggregation and coordination of multiple frequency bands, etc. It is expected to increase the rate and throughput by at least four times compared with the existing standards. Its main application scenarios are video transmission, AR (Augmented Reality), VR (Virtual Reality), etc.

[0003] Aggregation and coordination of multiple frequency bands means that devices can communicate simultaneously in the 2.4GHz, 5GHz and 6GHz frequency bands. For devices to communicate simultaneously in multiple frequency bands, a new MAC (Media Access Control) mechanism needs to be defined to manage it. In addition, it is also expected that the aggregation and coordination of multiple frequency bands can support low-latency transmission.

[0004] The maximum bandwidth currently supported by multi-band aggregation and system technology is 320MHz (160MHz+160MHz). In addition, 240MHz (160MHz+80MHz) and other bandwidths may also be supported.

[0005] In the prior art, in order to enable a station (STA) such as a terminal to quickly establish an initial connection with an access point (AP), a FILS (Fast Initial Link-setup) mechanism may be used. In this mechanism, the AP may broadcast an FD (FILS Discovery) frame to quickly establish an initial connection.

[0006] In addition, in current technology, a station (STA) and an access point (AP) can be a multi-link device (MLD), that is, it supports the function of simultaneously sending and / or receiving under multiple connections at the same time. Therefore, in current technology, there can be multiple connections between a STA and an AP, and research is being conducted on the communication between these two devices under multiple connections.

[0007] However, the FILS mechanism in the prior art is only applicable to single-connection communication between a station and an access point and is not applicable to multi-connection communication in the current technology, so it needs to be enhanced. Summary of the invention

[0027] Figure 1 It is an exemplary diagram showing a communication scenario under multiple connections.

[0028] In a wireless LAN, a basic service set (BSS) can be composed of an AP and one or more stations (STA) communicating with the AP. A basic service set can be connected to a distribution system (DS) through its AP, and then connected to another basic service set to form an extended service set (ESS).

[0029] AP is a wireless switch used in wireless networks and is also the core of wireless networks. AP devices can be used as wireless base stations, mainly as bridges to connect wireless networks and wired networks. Using this access point AP, wired and wireless networks can be integrated.

[0030] The AP may include software applications and / or circuits to enable other types of nodes in the wireless network to communicate with the outside and inside of the wireless network through the AP. In some examples, as an example, the AP may be a terminal device or network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0031] As an example, a station (STA) may include, but is not limited to, a cellular phone, a smart phone, a wearable device, a computer, a personal digital assistant (PDA), a personal communication system (PCS) device, a personal information manager (PIM), a personal navigation device (PND), a global positioning system, a multimedia device, an Internet of Things (IoT) device, etc.

[0032] In an exemplary embodiment of the present disclosure, an AP and a STA may support multi-connected devices, for example, may be represented as an AP MLD and a non-AP STA MLD, respectively. For ease of description, the following mainly describes an example in which an AP communicates with a STA under multi-connection, however, the exemplary embodiments of the present disclosure are not limited thereto.

[0033] exist Figure 1 In the example, the AP MLD may represent an access point supporting a multi-connection communication function, and the non-AP STA MLD may represent a station supporting a multi-connection communication function. Figure 1 , AP MLD can work under three connections, such as Figure 1 As shown in the figure, AP1, AP2 and AP3, non-AP STA MLD can also work under three connections, such as Figure 1 STA1, STA2 and STA3 are shown. Figure 1 In the example, it is assumed that AP1 communicates with STA1 through the corresponding first connection Link 1. Similarly, AP2 and AP3 communicate with STA2 and STA3 through the second connection Link 2 and the third connection Link 3, respectively. In addition, Link 1 to Link 3 can be multiple connections at different frequencies, for example, connections at 2.4 GHz, 5 GHz, 6 GHz bands, etc. or several connections with the same or different bandwidths at 2.4 GHz. In addition, multiple channels can exist under each connection. However, it should be understood that Figure 1 The communication scenarios shown are merely exemplary, and the present invention is not limited thereto. For example, an AP MLD may be connected to multiple non-AP STA MLDs, or in each connection, an AP may communicate with multiple other types of stations.

[0034] The communication method and communication device provided according to the embodiments of the present disclosure can be applied to Figure 1 The multi-connection communication environment shown.

[0035] Figure 2 is a flowchart illustrating a communication method under multiple connections according to an embodiment. Figure 2 The communication method shown can be applied to access points that support multi-connection communication, such as Figure 1 The AP MLD is shown.

[0036] Reference Figure 2In step 210, a first message frame may be determined. According to an embodiment, the first message frame may include: information indicating that a fast initial connection establishment (FILS) is performed under at least one connection in the multiple connections. In an embodiment of the present disclosure, the multiple connections may represent multiple connections that can be used for communication between the AP MLD and the non-AP STA MLD, such as Figure 1 The first connection Link 1 to the third connection Link 3 are shown.

[0037] In addition, in the embodiment of the present disclosure, there are many ways to determine the first message frame, for example, the first message frame can be generated according to at least one of the following conditions: network conditions, load conditions, hardware capabilities of the sending / receiving device, service types, and relevant protocol provisions; this embodiment of the present disclosure is not specifically limited. In the embodiment of the present disclosure, the first message frame can also be obtained from an external device, and this embodiment of the present disclosure is not specifically limited. The first message frame will be described in detail later with reference to Tables 1 to 6.

[0038] In step 220, a first message frame may be sent. For example, the first message frame may be sent in any connection among multiple connections. According to an embodiment, other connections may be quickly activated in one connection through information carried in the first message frame, thereby achieving fast initial connection establishment in multiple connections.

[0039] As a descriptive embodiment only, the first message frame may be a FILS discovery frame, i.e., an FD frame. The first message frame (FD frame) may be broadcast at a predetermined time interval (e.g., 20ms or 10ms) after the access point sends a beacon frame. When the station receives the broadcasted first message frame (FD frame), one or more connections may be established with the access point based on the information indicating FILS included therein. However, the present disclosure is not limited thereto, and any other type of frame is also included within the scope of the present disclosure. In the following, for ease of description, the first message frame and the information included therein are described by taking the FD frame as an example. For example, the first message frame (FD frame) may have a format as shown in Table 1 below.

[0040] Table 1. Format of the first message frame (FD frame)

[0041]

[0042] Although it is shown in Table 1 that the first message frame (FD frame) may include the Category, Public Action, FILS Discovery information field, Reduced Neighbor Report element, FILS Indication element, Roaming Consortium element and the like, it will be understood that the contents shown in Table 1 are only illustrative examples and not limitations on the present disclosure. For example, the first message frame (FD frame) may omit some of the contents shown in Table 1, or may include more other contents. In addition, it is understood that each content in Table 1 exists independently, and these contents are exemplarily listed in the same table, but it does not mean that all the contents in the table must exist at the same time as shown in the table. The value of each content is independent of any other content value in Table 1. Therefore, those skilled in the art can understand that the value of each content in Table 1 is an independent embodiment; and these contents in Table 1 can also be freely combined to form an embodiment.

[0043] In the following, for the sake of brevity, the description will focus on the FILS Discovery information field and the Reduced Neighbor Report element (RNRE) in Table 1 for implementing the FILS mechanism under multiple connections.

[0044] According to an embodiment of the present disclosure, the information included in the first message frame indicating that a fast initial connection establishment (FILS) is performed under at least one connection in the multiple connections may include a FILS discovery information field. The FILS discovery information field may carry information related to the FILS mechanism, for example, optionally, it may include: a FILS discovery frame control subfield (FILS DiscoveryFrame Control), a timestamp (Timestamp), a beacon frame interval (Beacon Interval), FD capability information (FDCapability), an operation type (Operation Class), a primary channel (Primary Channel), etc.

[0045] In order to achieve fast initial connection establishment under multiple connections, the FILS discovery information field according to an embodiment of the present disclosure may include an identification bit for indicating that the access point can support multi-connection communication. For example, the identification bit may be included in the FD capability information (FD Capability) subfield of the FILS discovery information field. As a descriptive embodiment, the FD capability information (FD Capability) subfield may have a format as shown in Table 2 below.

[0046] Table 2. Format of the FD Capability subfield

[0047]

[0048] Referring to Table 2, the flag bit of bit B8 can be used to indicate that the access point can support multi-connection communication. When the flag bit is carried in the FILS discovery information field of the first message frame (FD frame), the station receiving the first message frame (FD frame) can learn that the access point can support multi-connection communication by parsing the flag bit, so that other contents of the first message frame (FD frame) can be further parsed to obtain information of multiple access points corresponding to multiple connections, thereby realizing rapid initial connection establishment of multiple connections. It will be understood that the content shown in Table 2 is only an illustrative example and not a limitation of the present disclosure. For example, part of the content shown in Table 2 is omitted, or more other content may be included.

[0049] The access point broadcasts the first message frame (FD frame) so that the station can quickly establish an initial connection with it. In addition, since in the current technology, communication can be carried out under multiple connections, and the FD frame can optionally include a reduced neighbor report information element (RNRE), the access point can broadcast the connections it supports in the RNRE. According to an embodiment of the present disclosure, the information included in the first message frame indicating that a fast initial connection establishment (FILS) is to be performed under at least one connection in the multiple connections may include a reduced neighbor report information element. The reduced neighbor report information element can be used to identify relevant information of multiple connections supported by an access point that supports multi-connection communication. That is, in the reduced neighbor report information element, multiple access points belonging to the same AP MLD (for example, Figure 1 The AP MLD may contain information of AP1, AP2 and AP3 as shown, or may contain information of multiple access points belonging to different AP MLDs.

[0050] As an illustrative example only, the Reduced Neighbor Report Information Element (RNRE) may have the format shown in Table 3 below.

[0051] Table 3. Format of Reduced Neighbor Report Information Element (RNRE)

[0052]

[0053] Referring to Table 3, the element identifier (Element ID) can be used to identify the simplified neighbor report information element (RNRE), the length (Length) can be used to indicate the length of the simplified neighbor report information element (RNRE), and the neighbor AP information field (NeighborAP Information fields) can identify TBTT (target beacon transmission time) information and other information related to a group of neighbor APs.

[0054] As an example, the TBTT information may have a format as shown in Table 4 below.

[0055] Table 4. Format of the TBTT information field

[0056]

[0057] One or more TBTT information fields may be included in a Reduced Neighbor Report Information Element (RNRE). In some embodiments of the present disclosure, if the multiple connections included in the first message frame (FD frame) correspond to the various subordinate APs of the same AP MLD, only one TBTT information field may be included, and the information of each subordinate AP may be included in the MLD Parameters (MLDParameters) subfield. In other embodiments of the present disclosure, if the multiple connections included in the first message frame (FD frame) correspond to the various subordinate APs of different AP MLDs, multiple TBTT information fields may be included, and the MLD Parameters (MLD Parameters) subfield of each TBTT information field may contain information of each subordinate AP belonging to the corresponding AP MLD.

[0058] It will be understood that the contents shown in Table 4 are merely illustrative examples, and are not limitations on the present disclosure. For example, some of the contents shown in Table 4 may be omitted, or more other contents may be included. In addition, it is understood that each content in Table 4 exists independently, and these contents are exemplarily listed in the same table, but it does not mean that all the contents in the table must exist at the same time as shown in the table. The value of each content is independent of any other content value in Table 4. Therefore, those skilled in the art can understand that the value of each content in Table 4 is an independent embodiment; and these contents in Table 4 can also be freely combined to form an embodiment.

[0059] In Table 4, information of multiple access points of an access point supporting multi-connection communication (AP MLD) may be carried in the MLD Parameters subfield. As a descriptive embodiment, the MLD Parameters subfield may have a format as shown in Table 5 below.

[0060] Table 5. Format of the MLD Parameters subfield

[0061] MLD ID Link ID 1 Link ID 2 Link ID 3 ……

[0062] Referring to Table 5, the MLD Parameters subfield may include a multi-link device identifier (MLD ID) and at least one link identifier (Link ID 1 to Link ID 3).

[0063] In other words, according to an embodiment of the present disclosure, a simplified neighbor report information element may include a multi-connection device identifier (MLD ID), which may be used to identify the address of an access point (AP MLD) supporting multi-connection communication. The multi-connection device identifier (MLD ID) may be a unique identifier of the AP MLD, for example, an MLD MAC address. In addition, the simplified neighbor report information element may further include: multiple connection identifiers, which may be used to respectively identify multiple connections supported by the access point (AP MLD) supporting multi-connection communication. For example, the connection identifiers Link ID 1 to Link ID 3 in Table 5 identify the communication connections that the AP MLD can support, and are unique to the AP MLD.

[0064] Although only one multi-connection device identifier (MLD ID) and its corresponding connection identifier (LinkID 1 to Link ID 3) are shown in Table 5, the present disclosure is not limited thereto, and other multi-connection device identifiers (for example, MLD ID2 can be used to represent) and their corresponding connection identifiers (for example, Link ID 21, Link ID 22, etc. can be used to represent) can be included. In addition, the three connection identifiers Link ID 1 to Link ID 3 shown in Table 5 are only exemplary, and the present disclosure is not limited thereto, and more or fewer connection identifiers can be included.

[0065] In addition, the MLD parameter subfield in the simplified neighbor report information element may also include multiple offset time identifiers. Each offset time identifier may be used to identify the time offset (TBTT offset) at which the access point under the corresponding connection sends a target beacon transmission time (TBTT) beacon frame. In this case, the MLD parameter subfield shown in Table 5 may be changed to a format as shown in Table 6 below.

[0066] Table 6. Format of the MLD Parameters subfield

[0067]

[0068] Since a station can receive a reduced neighbor report information element (RNRE) under one connection, and an AP MLD can include multiple APs, and the time point at which each AP sends a beacon frame may be the same or different, an offset time identifier (TBTT offset) needs to be added to indicate the offset time for sending a beacon frame under each connection. It will be understood that the three offset time identifiers (TBTT offset1 to TBTT offset3) shown in Table 6 are only exemplary, and the present disclosure is not limited thereto, and more or fewer offset time identifiers may be included.

[0069] In addition, the MLD parameter subfield in the simplified neighbor report information element may also include content other than Table 5 and Table 6, for example, a change sequence. The change sequence may be used in common by multiple connections, for example, when a critical update occurs in the beacon frame of an access point under any connection, its value may change; or there may be multiple change sequences corresponding to multiple connections (such as Link ID 1 to Link ID 3), for example, when a critical update occurs in the beacon frame of an access point under a corresponding connection, the value of the corresponding change sequence may change.

[0070] According to the communication method of an embodiment of the present disclosure, the FILS discovery information field and the reduced neighbor report information element (RNRE) of the first message frame (FD frame) are defined to include information about multiple connections, so that the AP MLD and the non-AP STA MLD can quickly establish initial access and multiple connections.

[0074] According to an embodiment of the present disclosure, the simplified neighbor report information element may further include: multiple connection identifiers, which are respectively used to identify multiple connections supported by the access point supporting multi-connection communication.

[0075] According to an embodiment of the present disclosure, the simplified neighbor report information element may further include multiple offset time identifiers. Each offset time identifier may be used to identify the time offset of the target beacon transmission time (TBTT) beacon frame sent by the access point under the corresponding connection.

[0076] According to an embodiment of the present disclosure, the information in the first message frame indicating that a fast initial connection establishment (FILS) is performed under at least one connection in the multiple connections may also include a FILS discovery information field. The FILS discovery information field may include an identification bit for indicating an access point that supports multiple connection communication.

For example, after receiving the message frame (e.g., FD frame), the station can quickly activate the corresponding connection according to the information of at least one access point carried in the FD frame to achieve a fast initial connection establishment with the AP MLD under at least one connection in the multiple connections.
