Description

Technical Field

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

[0002] In May 2018, IEEE (Institute of Electrical and Electronic Engineers) established TG (Task group) IEEE802.11be to study the next generation (IEEE802.11a / b / g / n / ac) Wi-Fi technology. The research scope 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 IEEE802.11ax standard. 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, 5.8GHz and 6-7GHz 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, IEEE802.11be is also expected to support low-latency transmission.

[0004] In the discussion of the IEEE802.11be standard, the maximum bandwidth to be supported is 320MHz (160MHz+160MHz). In addition, 240MHz (160MHz+80MHz) and the bandwidth supported by the IEEE802.11ax standard may also be supported.

[0005] In the IEEE802.11be standard, a station (STA) and an access point (AP) can be a multi-link device (MLD), that is, it supports the function of sending and / or receiving simultaneously under multiple connections at the same time. Therefore, in the IEEE802.11be standard, there can be multiple connections between STA and AP. In the 802.11be standard, the communication between these two devices under multiple connections will be studied. However, in the existing standard, since multi-connection communication is not supported, address interaction under multiple connections is not possible. Summary of the invention

[0029] Figure 1 It is an exemplary diagram showing a communication scenario under multiple connections.

[0030] In a wireless LAN, a basic service set (BSS) can be composed of an AP and one or more stations (STAs) 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).

[0031] 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.

[0032] 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.

[0033] 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.

[0034] In an exemplary embodiment of the present disclosure, an AP and a STA may support multi-connected devices, for example, may be represented as AP MLD and non-AP 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.

[0035] exist Figure 1 In the example, the AP MLD may represent an access point supporting a multi-connection communication function, and the non-AP MLD may represent a station supporting a multi-connection communication function. Figure 1 , AP MLD can work under three connections, such as Figure 1 The non-AP MLD can also work under three connections, such as AP1, AP2 and AP3. 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, etc. or several connections at 2.4 GHz with the same or different bandwidths. In addition, multiple channels can exist under each connection. However, it should be understood that Figure 1The 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 MLDs, or in each connection, an AP may communicate with multiple other types of stations.

[0036] In order to support multi-connection communication, an embodiment of the present disclosure provides a communication method under multi-connection. Specifically, the communication method according to an embodiment of the present disclosure may include sending a message frame, wherein the message frame may include a multi-connection information element (ML element) for indicating multi-connection configuration information. That is to say, the communication method according to an embodiment of the present disclosure can be applied to any multi-connection device (MLD), and the multi-connection information element may include information related to the configuration of multiple connections that the multi-connection device can support. As an exemplary and non-restrictive description only, when the communication method according to an embodiment of the present disclosure is applied to an access point AP MLD, the message frame sent may be a beacon frame, an association response frame, or a multi-connection establishment request response frame; when the communication method according to an embodiment of the present disclosure is applied to a site non-AP MLD, the message frame sent may be a probe request frame, an association request frame, a reassociation request frame, or a multi-connection establishment request message frame.

[0037] In the following, reference will be made to Figure 2 and Figure 4 Examples in which the communication method according to an embodiment of the present disclosure is applied to an access point AP MLD and a station non-AP MLD are described respectively.

[0038] Figure 2 is a flow chart illustrating a communication method according to an example embodiment of the present disclosure. Figure 2 The communication method shown can be applied to an access point.

[0039] Reference Figure 2, in step 210, a first message frame may be determined. According to an embodiment, the first message frame may include a first multi-connection information element, which may be used to indicate multi-connection configuration information of an access point. For example, the first message frame may be determined by the AP under one of the multiple connections it supports. According to an example embodiment of the present disclosure, the first message frame may be a beacon frame or an association response frame broadcast by the AP, however, the example embodiment of the present disclosure is not limited thereto, and depending on the communication environment, the first message frame may be any other type of frame, such as a multi-connection establishment request response frame. In an example embodiment, the first message frame may be determined based on the software / hardware configuration, communication capabilities, and current communication environment of the AP. In another example embodiment, a pre-stored or pre-written first message frame may be directly obtained.

[0040] In step 220, a first message frame may be sent. For example, the first message frame may be sent through any connection of the plurality of connections. According to an embodiment, the connection used to determine the first message frame in step 210 and the connection used to send the first message frame in step 220 may be the same or different.

[0041] As an example, the format of the first multiple connection information element may be as shown in Table 1 below.

[0042] Table 1. Multi-Link Element

[0043]

[0044] Referring to Table 1, the element ID, length and element ID extension are similar to those defined in the existing standards, and are not described in detail in this disclosure.

[0045] In Table 1, the first multi-connection information element may include: a multi-connection device MAC address identifier indicating the MAC address of the access point (i.e., "MLD MAC Address" in Table 1). According to an embodiment, a multi-connection device (e.g., AP MLD) may have a unique multi-connection device MAC address identifier for identifying the multi-connection device (e.g., AP MLD). According to an embodiment, when the communication quality is poor and one of the multiple connections cannot be identified, the access point AP MLD to which the connection belongs can be identified by the multi-connection device MAC address identifier (MLD MAC Address), so that communication can continue using other connections of the identified access point AP MLD.

[0046] In Table 1, the details of the optional subelements can be as follows: Figure 3 In order to implement address exchange under multiple connections in the interaction between AP MLD and non-AP MLD, Figure 3 The per-STA profile x subfield of the AP MLD may include multiple connections supported by the AP MLD (for example, Figure 1 The MAC address identifier corresponding to each connection in AP1 to AP3) shown in FIG. 1 is shown in Table 2 below. As an example, the content shown in Table 2 may be included in the data of the per-STA profile. Figure 3 In the "per-STA profile", the "STA" in a broad sense usually refers to access point APMLD and station non-AP MLD. Figure 3 When the example of the multi-connection information element shown is applied to the first message frame of the access point AP MLD, the "STA" in the "per-STA profile" may correspond to the access point AP MLD; in addition, in the following reference Figure 4 In the communication method described, when Figure 3 When the example of the multi-connection information element shown is applied to the second message frame of the station non-AP MLD, the "STA" in the "per-STA profile" may correspond to the station non-AP MLD.

[0047] Table 2. MAC address identification of multiple connections

[0048]

[0049] Referring to Table 2, the first multiple connection information element may include: a MAC address identifier (MAC 1 to MAC n) corresponding to each of the multiple connections of the access point AP MLD and a connection identifier (Link ID1 to Link IDn) corresponding to each of the multiple connections of the access point AP MLD. The MAC address identifier (MAC 1 to MAC n) corresponding to each of the multiple connections of the access point AP MLD can be used to identify the MAC address under each connection (for example, Figure 1In other words, although the AP MLD may have a unique multi-connection device MAC address identifier ("MLD MAC Address" in Table 1), each connection of the AP MLD may have a different MAC address identifier (MAC 1 to MAC n in Table 2). According to an embodiment, setting the MAC address identifier of each connection may ensure the security of communication. For example, in secure encrypted communication, a corresponding key may be generated according to the MAC address of each connection. The quality of communication may also be ensured. For example, when a communication failure occurs in one connection, communication may continue according to the MAC addresses of other connections.

[0050] In addition, in other embodiments, the connection identifier (Link ID1 to Link IDn) may also be omitted. For example, the MAC address identifier corresponding to each connection may be identified in Table 2 in order of the frequency of each connection, so that the connection identifier (Link ID1 to Link IDn) may be omitted. However, this is merely exemplary and the embodiments of the present disclosure are not limited to this.

[0051] In the embodiment of Table 1, the multi-connection device MAC address identifier ("MLD MAC Address" in Table 1) and the MAC address identifiers of each connection ("MAC 1 to MAC n" in Table 2) can be respectively included in different subfields in the first multi-connection information element. Although, in the embodiment of Table 1, it is shown that the first multi-connection information element can include MLD MACAddress and MAC1 to MAC n, however, the embodiments of the present disclosure are not limited to this. For example, in some cases (for example, when the communication quality is good), MLD MAC Address can also be omitted.

[0052] In addition, the first multi-connection information element may also include: a connection quantity identifier indicating the number of multiple connections of the access point. For example, the connection quantity identifier may be included in the multi-link control (Multi-Link Control) of Table 1, such as the "number of supported links" shown in B0-B2 in Table 3 below.

[0053] Table 3. Multi-Link Control

[0054]

[0055] According to an embodiment, the first message frame may further include: a capability information identifier indicating that the access point can support multi-connection communication. For example, the access point AP MLD may carry the capability information identifier in a beacon frame for broadcasting to notify the station receiving the beacon frame that it can obtain the capability information of the access point AP MLD. In the example, the capability information identifier may be represented in the form of a capability information element (Capability Info Element) of the first message frame.

[0056] Figure 4 is a flow chart illustrating a communication method according to an example embodiment of the present disclosure. Figure 4 The communication method shown can be applied to a station (e.g., Figure 1 non-AP MLD).

[0057] Reference Figure 4 , in step 410, a second message frame may be determined. According to an embodiment, the second message frame may include a second multi-connection information element, wherein the second multi-connection information element may be used to indicate the multi-connection configuration information of the site. According to an embodiment, the second multi-connection information element may include: a multi-connection device MAC address identifier indicating the MAC address of the site, and / or a MAC address identifier corresponding to each connection of the multiple connections of the site. For example, the second message frame may be determined by the site under one of the multiple connections supported by the site. According to an example embodiment of the present disclosure, the second message frame may be a probe request frame, an association request frame, or a reassociation request frame sent by the site, however, the example embodiment of the present disclosure is not limited thereto, and according to the communication environment, the second message frame may be any other type of frame, such as a multi-connection establishment request message frame. In an example embodiment, the second message frame may be determined based on the software / hardware configuration, communication capability, and current communication environment of the site. In another example embodiment, a pre-stored or pre-written second message frame may be directly obtained.

[0058] According to an embodiment, the second multiple connection information element may further include: a connection identifier corresponding to each connection of the multiple connections of the site.

[0059] According to an embodiment, the second multiple connection information element may further include: a connection quantity identifier indicating the number of multiple connections of the site.

[0060] The second multi-connection information element and the multi-connection device MAC address identifier, the MAC address identifier corresponding to each connection, the connection identifier corresponding to each connection, and the connection quantity identifier included therein may be similar to those in Tables 1 and 2 and Figure 3For the sake of simplicity, the repeated description of the described format is omitted here. Similar to Table 1, the multi-connection device MAC address identifier of the station non-AP MLD and the MAC address identifier corresponding to each connection can be included in different subfields in the second multi-connection information element.

[0061] In one example, in response to the site being in enhanced single radio multi-link (ESRML) mode, the second multi-connection information element may be set to include a multi-connection device MAC address identifier. That is, in ESRML mode, the address of each connection in the site non-AP MLD may be a multi-connection device MAC address identifier. However, this is merely exemplary, and the embodiments of the present disclosure are not limited thereto. For example, in this mode, the addresses of the various connections may also be different.

[0062] In addition, according to an embodiment, the second message frame may further include: a capability information identifier indicating that the site can support multi-connection communication. For example, the site non-AP MLD may carry the capability information identifier in a probe request frame, an association request frame, a reassociation request frame, or a multi-connection establishment request message frame, etc., for broadcasting to notify the access point that receives the corresponding frame that it can obtain the capability information of the site non-AP MLD. In the example, the capability information identifier may be represented in the form of a capability information element (Capability Info Element) of the second message frame.

[0063] In step 420, a second message frame may be sent. For example, the second message frame may be sent through any connection of the plurality of connections. According to an embodiment, the connection used to determine the second message frame in step 410 and the connection used to send the second message frame in step 420 may be the same or different.

[0064] Figure 2 and Figure 4 The communication method shown is only exemplary and the present disclosure is not limited thereto. Figure 2 The communication method may further include the access point receiving a second message frame from the station, thereby obtaining a multi-connection device MAC address identifier of the station and / or a MAC address identifier corresponding to each connection of the station by parsing the second message frame; Figure 4 The communication method shown may also include the station receiving a first message frame from the access point, thereby obtaining the multi-connection device MAC address identifier of the access point and / or the MAC address identifier corresponding to each connection of the station by parsing the first message frame. Figure 5is a diagram illustrating interactive communication between an access point and a station according to an example embodiment, wherein the first message frame may be a beacon frame, an association response frame, or a multi-connection establishment request response frame, etc., the second message frame may be a probe request frame, an association request frame, a reassociation request frame, or a multi-connection establishment request message frame, etc., and the first message frame and the second message frame may carry the multi-connection information element (ML element) as described above to interact with MAC addresses (i.e., a multi-connection device MAC address identifier and / or a MAC address identifier corresponding to each connection). Figure 5 The interactive communication process shown is only exemplary, and the embodiments of the present disclosure are not limited thereto. For example, the interactive sequence of the first message frame and the second message frame may be appropriately changed according to the communication status.

[0065] When the access point and the station complete the initial access (multiple connections are established), but do not interact with the receiver address (RA: receiver address) / transmitter address (TA: transmitter address) under each connection, additional signaling is required for interaction. Figure 5 The interactive communication shown can be performed when multiple connections are established. The access point of the multi-connection device and the site of the multi-connection device can obtain each other's multi-connection device MAC address identifiers and / or MAC address identifiers corresponding to each connection through the first message frame and the second message frame defined above. In this way, RA / TA interaction under multiple connections can be performed when multiple connections are established, thereby saving signaling interaction.
