Description

[Technical field]

[0001] The present disclosure relates to the field of wireless communication, and more particularly to a communication method and device in multi-connection. [Background technology]

[0002] The current research scope of Wi-Fi technology includes 320MHz bandwidth transmission, aggregation and cooperation of multiple frequency bands, etc., and it is expected to improve speed and throughput by at least four times compared to conventional standards. Its main application scenarios include video transmission, AR (Augmented Reality), VR (Virtual Reality), etc.

[0003] Aggregation and cooperation of multiple frequency bands refers to simultaneous communication between devices in the 2.4GHz, 5GHz and 6GHz frequency bands, and a new MAC (Media Access Control) mechanism needs to be defined and managed for simultaneous communication between devices in multiple frequency bands. In addition, aggregation and cooperation of multiple frequency bands is expected to support low latency transmission.

[0004] With current multi-frequency band aggregation and system technology, the maximum bandwidth supported is 320MHz (160MHz+160MHz), and may also support 240MHz (160MHz+80MHz) and other bandwidths.

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

[0006] In addition, in current technology, a station (STA) and an access point (AP) may be a multi-link device (MLD), i.e., a function capable of simultaneously transmitting and / or receiving via multiple connections at the same time is supported. Thus, in current technology, multiple connections can exist between a STA and an AP, and research is being conducted into communication between these two devices in multiple connections.

[0007] However, the FILS mechanism in the prior art only applies to single-connection communication between a site and an access point, and does not apply to multi-connection communication in the current technology, so an extension is needed.

[0023] FIG. 1 is a diagram showing an example of a communication scenario in multi-connection.

[0024] In a wireless LAN, a Basic Service Set (BSS) may consist of an AP and one or more Sites (STAs) that communicate with the AP. A Basic Service Set can connect to a Distribution System (DS) through its AP and access another Basic Service Set to form an Extended Service Set (ESS).

[0025] AP is a wireless switch for wireless network and also the core of the network. AP device can be mainly used as a bridge to connect wireless network and wired network. By using this type of access point AP, wired and wireless network can be integrated.

[0026] An AP may include software applications and / or circuitry to enable other types of nodes in a wireless network to communicate with the outside and inside of the wireless network through the AP. In some embodiments, for example, an AP may be a terminal device or a network device equipped with a Wi-Fi (Wireless Fidelity) chip.

[0027] By way of example, a site (STA) may include, but is not limited to, a mobile 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, and the like.

[0028] In the exemplary embodiment of the present disclosure, the AP and the STA can support multi-connection devices, and can be represented as AP MLD and non-AP STA MLD, respectively. For ease of explanation, the following mainly describes an example in which one AP and one STA communicate with multi-connection, but the exemplary embodiment of the present disclosure is not limited thereto.

[0029] In FIG. 1, merely as an example, AP MLD can represent an access point supporting a multi-connection communication function, and non-AP STA MLD can represent a site supporting a multi-connection communication function. Referring to FIG. 1, AP MLD can operate with three connections, AP1, AP2, and AP3, as shown in FIG. 1, and non-AP STA MLD can also operate with three connections, STA1, STA2, and STA3, as shown in FIG. 1. In the example of FIG. 1, assuming that AP1 and STA1 communicate through a corresponding first connection Link1, similarly, AP2 and AP3 communicate with STA2 and STA3 through a second connection Link2 and a third connection Link3, respectively. Also, Link1 to Link3 may be multiple connections at different frequencies, such as connections in 2.4GHz, 5GHz, and 6GHz frequency bands, or several same or different bandwidth connections in 2.4GHz. Also, there may be multiple channels in each connection. However, it should be understood that the communication scenario illustrated in FIG. 1 is merely exemplary, and the inventive concept is not limited thereto, for example, an AP MLD can connect to multiple non-AP STA MLDs, or in each connection, an AP can communicate with multiple other types of sites.

[0030] The communication method and communication device provided by the embodiments of the present disclosure can be applied to the multi-connection communication environment shown in FIG.

[0031] 2 is a flowchart illustrating a communication method in multi-connection according to an embodiment of the present invention, which can be applied to an access point supporting multi-connection communication, such as AP MLD shown in FIG.

[0032] Referring to Fig. 2, in 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 on at least one connection of the multiple connections. In an embodiment of the present disclosure, the multiple connections may represent multiple connections available for communication between an AP MLD and a non-AP STA MLD, such as the first connection Link1 to the third connection Link3 shown in Fig. 1.

[0033] In addition, in the embodiment of the present disclosure, the manner of determining the first message frame may be various, for example, the first message frame may be generated based on at least one of the network condition, the load condition, the hardware capability of the transmitting / receiving device, the service type, and the related protocol specification, and the embodiment of the present disclosure is not specifically limited. In the embodiment of the present disclosure, the first message frame may also be obtained from an external device, and the 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.

[0034] In step 220, a first message frame may be transmitted. For example, the first message frame may be transmitted on any of the multiple connections. According to an embodiment, through information carried in the first message frame, one connection may quickly activate other connections, thereby realizing a quick initial connection establishment in the multiple connections.

[0035] As an illustrative example only, the first message frame may be a FILS discovery frame, i.e., an FD frame. After an access point transmits a beacon frame, it may broadcast one message frame (FD frame) at a predetermined time interval (e.g., 20 ms or 10 ms). When a site receives the broadcasted first message frame (FD frame), it may establish one or more connections with the access point based on the information indicating FILS contained 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 explanation, the first message frame and the information contained therein are described using an FD frame as an example. For example, the first message frame (FD frame) may have a format shown in Table 1 below.

[0036] [Table 1]

[0037] As shown in Table 1, the first message frame (FD frame) may include contents such as Category, Public Action, FILS Discovery information field, Reduced Neighbor Report element, FILS Indication element, Roaming Consortium element, etc., but it should be understood that the contents shown in Table 1 are merely illustrative examples and are not limitations of the present disclosure. For example, the first message frame (FD frame) may omit partial contents shown in Table 1, or may include more other contents. Also, it should be understood that each content in Table 1 exists independently, and although these contents are exemplarily listed in the same table, it does not represent that all contents in the table should exist simultaneously as shown in the contents. The value of each content is a value that does not depend on any other content value in Table 1. Therefore, those skilled in the art can understand that the value of each content in this Table 1 is an independent embodiment, and these contents in Table 1 can also be freely combined to form an embodiment.

[0038] In the following, for ease of explanation, the FILS discovery information field and the Reduced Neighbor Report element (RNRE) for realizing the FILS mechanism in multi-connection in Table 1 will be collectively explained.

[0039] According to an embodiment of the present disclosure, the information included in the first message frame indicating a Rapid Initial Connection Establishment (FILS) for at least one of the multiple connections may include a FILS discovery information field. The FILS discovery information field may carry information about a FILS mechanism, and may selectively include, for example, a FILS discovery frame control subfield, a timestamp, a beacon frame interval, FD capability information, an operation class, a primary channel, etc.

[0040] In order to realize a fast initial connection establishment in multi-connection, the FILS discovery information field according to the 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 an FD Capability subfield of the FILS discovery information field. As an illustrative example, the FD Capability subfield may have a format shown in Table 2 below.

[0041] [Table 2]

[0042] Referring to Table 2, the identification bit of bit B8 can be used to indicate that the access point can support multi-connection communication. When this identification bit is carried in the FILS discovery information field of the first message frame (FD frame), the site receiving the first message frame (FD frame) can know that the access point can support multi-connection communication by analyzing the identification bit, and can further analyze other contents of the first message frame (FD frame) to obtain information of multiple access points corresponding to multiple connections, thereby realizing rapid initial connection establishment of multiple connections. It should be understood that the contents shown in Table 2 are only illustrative examples, not limitations of the present disclosure. For example, some of the contents shown in Table 2 can be omitted, or more other contents can be included.

[0043] The access point broadcasts the first message frame (FD frame) so that the site can quickly establish an initial connection with it. In the current technology, the access point can communicate in multiple connections, and the FD frame can optionally include a reduced neighbor report element (RNRE), so that the access point can broadcast the connections supported in the RNRE. According to an embodiment of the present disclosure, the information indicating that at least one of the multiple connections included in the first message frame performs a fast initial connection establishment (FILS) can include a reduced neighbor report element. The reduced neighbor report element can be used to identify information related to multiple connections supported by an access point that supports communication in multiple connections. That is, the reduced neighbor report element can include information of multiple access points belonging to the same AP MLD (e.g., AP1, AP2, and AP3 shown in FIG. 1) or information of multiple access points belonging to different AP MLDs.

[0044] As an illustrative example only, a Reduced Neighborhood Report Element (RNRE) may have the format shown in Table 3 below.

[0045] [Table 3]

[0046] Referring to Table 3, the element identifier (Element ID) can be used to identify the reduced neighbor report element (RNRE), the length (Length) can be used to indicate the length of the reduced neighbor report element (RNRE), and the Neighbor AP Information fields can identify TBTT (target beacon transmission time) information and other information associated with a set of neighbor APs.

[0047] As an example, the TBTT information may have the format shown in Table 4 below.

[0048] [Table 4]

[0049] The reduced neighbor report element (RNRE) may include one or more TBTT information fields. In some embodiments of the present disclosure, if the multiple connections included in the first message frame (FD frame) correspond to each attached AP of the same AP MLD, only one TBTT information field may be included, and information of each attached AP may be included in the MLD Parameters subfield. In some other embodiments of the present disclosure, if the multiple connections included in the first message frame (FD frame) correspond to each attached AP of different AP MLDs, multiple TBTT information fields may be included, and the MLD Parameters subfield of each TBTT information field may include information of each attached AP belonging to the corresponding AP MLD.

[0050] It should be understood that the contents shown in Table 4 are merely illustrative examples and are not limitations of the present disclosure. For example, some contents shown in Table 4 may be omitted or other contents may be included. In addition, each content in Table 4 exists independently, and although these contents are exemplarily listed in the same table, it can be understood that all contents shown in the table should not exist simultaneously as shown in the table. The value of each content therein is a value that does not depend on any other content value in Table 4. Therefore, a person skilled in the art can understand that the value of each content in this Table 4 is an independent embodiment, and these contents in Table 4 can also be freely combined to form an embodiment.

[0051] In Table 4, information of multiple access points of an access point supporting multi-connection communication (AP MLD) can be carried in the MLD Parameters subfield. As an illustrative example, the MLD Parameters subfield can have the format shown in Table 5 below.

[0052] [Table 5]

[0053] Referring to Table 5, the MLD Parameters subfield may include a multi-connection device identifier (MLD ID) and at least one connection identifier (Link ID 1 to Link ID 3).

[0054] In other words, according to an embodiment of the present disclosure, the reduced neighbor report element may include a multi-connection device identifier (MLD ID) that can be used to identify an address of an access point (AP MLD) that supports multi-connection communication. The multi-connection device identifier (MLD ID) is a unique identifier of the AP MLD, for example, an MLD MAC address. The reduced neighbor report element may further include multiple connection identifiers that can be respectively used to identify multiple connections supported by the access point (AP MLD) that supports multi-connection communication. For example, the connection identifiers Link ID 1 to Link ID 3 in Table 5 identify communication connections that the AP MLD can support and are unique to the AP MLD.

[0055] In Table 5, only one multi-connection device identifier (MLD ID) and its corresponding connection identifiers (Link ID 1 to Link ID 3) are shown, but the present disclosure is not limited thereto and may include other multi-connection device identifiers (which may be represented by MLD ID2) and their corresponding connection identifiers (e.g., which may be represented by Link ID 21, Link ID 22). Also, the three connection identifiers Link ID 1 to Link ID3 shown in Table 5 are exemplary, and the present disclosure is not limited thereto and may include more or less connection identifiers.

[0056] Additionally, the MLD parameters subfield in the reduced neighbor report element may further include a plurality of offset time identifiers. Each offset time identifier may be used to identify a time offset (TBTT offset) of a target beacon frame transmission time (TBTT) beacon frame transmitted by an access point using a corresponding connection. In this case, the MLD parameters subfield shown in Table 5 may be modified to a format as shown in Table 6 below.

[0057] [Table 6]

[0058] Since a site may receive a reduced neighbor report element (RNRE) in one connection, and an AP MLD may include multiple APs, and the time at which each AP transmits a beacon frame may be the same or different, an offset time identifier (TBTT offset) needs to be added to indicate the offset time at which each connection transmits a beacon frame. It should be understood that the three offset time identifiers (TBTT offset 1 to TBTT offset 3) shown in Table 6 are exemplary, and the present disclosure is not limited thereto, and may include more or less offset time identifiers.

[0059] In addition, the MLD parameters subfield in the reduced neighbor report element may further include content other than those in Tables 5 and 6, such as a change sequence. This change sequence may be used in common by multiple connections, and for example, when a key update occurs in a beacon frame of an access point in any connection, the value of the change sequence is changed. Alternatively, there may be multiple change sequences corresponding to multiple connections (e.g., Link ID 1 to Link ID 3), and for example, when a key update occurs in a beacon frame of an access point in a corresponding connection, the value of the corresponding change sequence is changed.

[0060] A communication method according to an embodiment of the present disclosure defines a FILS discovery information field and a reduced neighbor report element (RNRE) in a first message frame (FD frame) to include information related to multi-connection, thereby enabling AP MLD and non-AP STA MLD to quickly establish initial access and multi-connection establishment.

[0061] 3 is a flowchart illustrating another communication method in multi-connection according to an embodiment. The communication method illustrated in FIG. 3 can be applied to a site supporting multi-connection (non-AP STA MLD as shown in FIG. 1).

[0062] 3, in step 310, a first message frame may be received, where the first message frame may include information indicating performing a Rapid Initial Connection Establishment (FILS) on at least one connection of the multiple connections, and the information may include a Reduced Neighbor Report element for identifying relevant information of the multiple connections supported by the access point supporting the multi-connection communication. For example, the first message frame may be received on any connection of the multiple connections supported by non-AP STA MLD.

[0063] According to an embodiment of the present disclosure, the reduced neighborhood report element may include a multi-connection device identifier to identify an address of an access point that supports multi-connection communication.

[0064] According to an embodiment of the present disclosure, the reduced neighborhood report element may further include a number of connection identifiers for respectively identifying a number of connections supported by the access point supporting multi-connection communication.

[0065] According to an embodiment of the present disclosure, the reduced neighborhood report element can further include a plurality of offset time identifiers, each offset time identifier identifying a time offset of a target beacon frame transmission time (TBTT) beacon frame transmitted by an access point using a corresponding connection.

[0066] According to an embodiment of the present disclosure, the information indicating a fast initial connection establishment (FILS) for at least one of the multiple connections in the first message frame may further include a FILS discovery information field, which may include an identification bit for indicating an access point that supports multi-connection communication.

[0067] The first message frame, reduced neighborhood report element, and FILS discovery information field of step 310 are similar to the embodiments described with reference to Tables 1 to 6, and therefore, for ease of explanation, duplicate descriptions are omitted here.

[0068] In step 320, perform a communication operation based on the first message frame. For example, after receiving a message frame (e.g., an FD frame), the site can quickly activate a corresponding connection based on the information of at least one access point carried in the FD frame, so as to realize a quick initial connection establishment with the AP MLD for at least one connection of the multiple connections.

In this case, the communication device 400 can execute the communication method described with reference to FIG. 2, and for ease of explanation, the duplicated description will be omitted here. The first message frame, the reduced neighbor report element, and the FILS discovery information field described with reference to Tables 1 to 6 can be applied here, and for ease of explanation, the duplicated description will be omitted here.

In this case, the communication device 400 may perform the communication method described with reference to FIG. 3, and for ease of explanation, the duplicated description will be omitted here.
