Description

Technical Field

[0001] The present disclosure relates to the field of communications, and more particularly, to a communication method and a communication device in wireless communications. Background Art

[0002] Current Wi-Fi technology research focuses on 320MHz bandwidth transmission, aggregation and coordination of multiple frequency bands, and is expected to increase speed and throughput by at least four times compared to existing standards. Its main application scenarios include video transmission, augmented reality (AR), and virtual reality (VR).

[0003] Aggregation and coordination of multiple frequency bands means that devices can communicate simultaneously across the 2.4 GHz, 5.8 GHz, and 6-7 GHz frequency bands. This simultaneous communication between devices requires the definition of a new MAC (Media Access Control) mechanism to manage this. Furthermore, it is expected that this multi-band aggregation and coordination will 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 actual applications, various types of stations (STAs) may coexist in a network, such as stations supporting high throughput (HT) communication (hereinafter referred to as "HT stations"), stations supporting high efficiency (HE) communication (hereinafter referred to as "HE stations"), stations supporting very high throughput (VHT) communication (hereinafter referred to as "VHT stations"), and / or stations supporting extremely high throughput (EHT) communication (hereinafter referred to as "EHT stations"), etc. When an EHT station is capable of operating as a Soft AP (soft access point), it can communicate with various stations in the network.

[0006] According to existing standards, when an EHT station works as a Soft AP and communicates with various stations in the network, it will cause waste of frequency bands (for example, the 6 GHz band) and fail to meet the vision of multi-connection communication. Summary of the Invention

[0025] Unless otherwise defined, all terms (including technical and scientific terms) used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

[0026] Figure 1 is an exemplary diagram illustrating a wireless communication scenario.

[0027] Reference Figure 1 In a wireless local area network, multiple stations (STAs) may exist, wherein an EHT station, acting as a Soft AP, can communicate with multiple other stations (e.g., stations 1 to 4). Each of stations 1 to 4 may be an HT station, HE station, VHT station, or EHT station, etc. However, it should be understood that the present disclosure is merely illustrative of HT stations, HE stations, VHT stations, and EHT stations, and does not limit the scope of the embodiments of the present disclosure. For example, stations supporting other communication capabilities are also within the scope of the present disclosure. Furthermore, while the present disclosure describes an embodiment using an EHT station as an example of a Soft AP, the present disclosure is not limited thereto. For example, HE stations, etc., may also serve as Soft APs. As examples, stations may be various devices capable of wireless communication, such as cellular phones, smartphones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers (PIMs), personal navigation devices (PNDs), global positioning systems, multimedia devices, Internet of Things (IoT) devices, etc.

[0028] The IEEE802.11be standard defines a mechanism to support the operation of Non-STR AP (non-synchronous transmission / reception Access Point) MLD (multi-link device). Non-STR AP MLD means that the AP MLD (access point multi-link device) can transmit or receive simultaneously under multiple connections at the same time, that is, the access point multi-link device can only receive or transmit at the same time, not receive and transmit at the same time. This mechanism is limited to using Non-STR Non-AP (non-AP device) MLD as a Soft AP that utilizes all its connections, for example, Figure 1 The EHT station in can serve as the Non-STR Soft AP MLD. For the convenience of description, the Non-STR Soft AP MLD and Soft AP are used interchangeably in the following text.

[0029] In an embodiment, the connections supported by the Soft AP can be described as a basic link set and a conditional link. Specifically, in the basic link set, under paired connections, the Non-STR Soft AP MLD can send and receive frames simultaneously with other multi-connection devices. As an example, the paired connections in the basic connection set may include {2.4GHz connection, 5GHz connection} or {2.4GHz connection, 6GHz connection}. In addition, under conditional connections and some connections in the basic connection set, the Non-STR Soft AP MLD cannot send and receive frames simultaneously with other multi-connection devices. These connections in the basic connection set can be referred to as the corresponding basic connections for the conditional connection. For example, if {2.4GHz connection, 5GHz connection} is the basic connection set, then the 6GHz connection is the conditional connection corresponding to the 5GHz connection.

[0030] For example, a wireless network may include HE stations (supporting 2.4 GHz, 5 GHz, and 6 GHz), VHT stations (supporting 2.4 GHz and 5 GHz), and EHT stations (supporting 2.4 GHz, 5 GHz, and 6 GHz). If an EHT station is capable of operating as a Soft AP, then an EHT station operating as a Soft AP can communicate with both the VHT station and the HE station and / or other EHT stations (stations not functioning as Soft APs). For example, since a VHT station operates in the 5 GHz and 2.4 GHz bands, an EHT station operating as a Soft AP can only communicate with the VHT station in the 2.4 GHz or 5 GHz bands, but can communicate with the HE station and / or other EHT stations in the 2.4 GHz, 5 GHz, and 6 GHz bands. If an EHT station acting as a Soft AP first establishes a Basic Service Set (BSS) with a VHT station in the 2.4 GHz or 5 GHz frequency band, then according to existing standards, the HE station and / or other EHT stations can only access the EHT station acting as a Soft AP in the 2.4 GHz or 5 GHz frequency band, and cannot establish a BSS with the EHT station acting as a Soft AP in the 6 GHz frequency band (assuming that the interference is small but the bandwidth is large). This results in a waste of the 6 GHz frequency band. To this end, embodiments of the present disclosure provide a communication method that can improve spectrum utilization efficiency and increase throughput.

[0031] In all embodiments of the present disclosure, the 2.4 GHz, 5 GHz, and 6 GHz frequency bands are used as examples. However, it should be noted that these frequency bands are merely examples and do not limit the scope of the embodiments of the present disclosure. The embodiments of the present disclosure do not impose any restrictions on the frequency bands supported by different standards; any frequency band with any numerical value is within the scope of protection of the embodiments of the present disclosure.

[0032] Figure 2 is a flowchart illustrating a communication method according to an example embodiment of the present disclosure. Figure 2 The method can be applied to Figure 1 The EHT site shown in FIG as a Soft AP (for the sake of brevity of description, it may be referred to as a “Soft AP” hereinafter).

[0033] Reference Figure 2 In step 210, a first message frame may be determined and sent. The first message frame may include information indicating that the first device sending the first message frame (i.e., an EHT station capable of serving as a Soft AP) supports a soft access function, wherein the information about supporting the soft access function is in an EHT capability information element of the first message frame.

[0034] In embodiments of the present disclosure, there are various ways to determine the first message frame. For example, the Soft AP may generate the first message frame based on at least one of the following: network conditions, load conditions, hardware capabilities of the transmitting / receiving device, service type, or relevant protocol specifications; this is not specifically limited in embodiments of the present disclosure. In embodiments of the present disclosure, the Soft AP may also obtain the first message frame from an external device; this is not specifically limited in embodiments of the present disclosure.

[0035] In an embodiment of the present disclosure, the first message frame may be a probe request frame, a multi-link probe request (ML probe request) frame, an association request frame, or a re-association request frame, etc. However, this is merely an exemplary description, and the embodiments of the present disclosure are not limited thereto.

[0036] In an embodiment of the present disclosure, if the EHT station supports the Soft AP function, it may be broadcasted in a probe request frame, an ML probe request frame, an association request, or a re-association request frame.

[0037] In step 220, a second message frame may be received. The second message frame may include: frequency band information supported by a second device located around the first device. In an embodiment of the present disclosure, the first device may correspond to Figure 1 The second device may correspond to the SoftAP shown in Figure 1 1 to 4 shown in . For example, the second message frame may be a response frame to a probe request frame, a multi-connection probe request frame, an association request frame, or a reassociation request frame sent by the first device, but the present disclosure is not limited thereto. For example, the second message frame may be various management frames, control frames, or data frames sent by stations surrounding the Soft AP, and the present disclosure does not specifically limit this.

[0038] The Soft AP can collect the frequency band information supported by the surrounding stations through the second message frame. Specifically, when receiving the second message frame from the surrounding stations, the Soft AP can determine the frequency band information supported by the corresponding station from the second message frame. In one embodiment, the frequency band information supported by the second device is determined based on the capability information of the second message frame. As an example, the capability information may include at least one of the following items: high throughput (HT) capability information; very high throughput (VHT) capability information; high efficiency (HE) capability information; and extremely high throughput (EHT) capability information. The Soft AP can preliminarily determine which standard the corresponding station supports from the capability information of the second message frame, and thereby preliminarily determine the frequency band information that the corresponding station may support.

[0039] In one embodiment, the frequency band information supported by the second device is determined based on the frequency band identification field of the second message frame. For example, the second message frame may include a frequency band identification information element (Band ID element), and the Soft AP may specifically determine the frequency bands supported by the corresponding station based on the frequency band identification (Band ID) field in the Band ID element in the second message frame sent by each station.

[0040] According to an embodiment of the present disclosure, an EHT station acting as a Soft AP may collect supported frequency band information of surrounding stations. Specifically, for HT stations, the EHT station acting as a Soft AP may parse their HT capability information element, for VHT stations, the VHT capability information element, and for HE stations, the HE capability information element. For other EHT stations, the EHT capability information element may be parsed; or the Band ID field in the Band ID element of each station may be parsed, as shown in Table 1 below:

[0041] Table 1. Band ID field

[0042] Band ID value meaning 0 TV white space 1 Sub-1GHz (excluding TV white space) 2 2.4GHz 3 3.6GHz 4 4.9 and 5GHz 5 60GHz 6 45GHz 7 6GHz 8-255 Reserved

[0043] In Table 1, if the station is a HE station or an EHT station, the Band ID value can be 7 to indicate that it supports the 6 GHz band. It will be understood that the values ​​in Table 1 are for illustrative purposes only and are not intended to limit the embodiments of the present disclosure.

[0044] When the Soft AP collects frequency band information supported by surrounding sites, it can establish a basic service set based on the collected frequency band information.

[0045] Although not shown, according to an embodiment of the present disclosure, Figure 2 The communication method shown may further include: classifying the second device based on the frequency band information; and according to the classification result, establishing a basic service set (BSS) or an ad hoc (Ad-Hoc) network with the second device in different frequency bands. As an example, the Soft AP may send a beacon frame in the corresponding frequency band to establish a BSS or Ad-Hoc with the second device. However, establishing a BSS Ad-Hoc in the form of a beacon frame is only an exemplary description, and the present disclosure is not limited thereto. In the following, the embodiments are mainly described by taking the establishment of a BSS as an example, but the embodiments for establishing a BSS may also be applicable to establishing an Ad-Hoc network. For the sake of simplicity, repeated descriptions are omitted.

[0046] In an embodiment of the present disclosure, the Soft AP may classify the second device based on the capability information and / or BandID field included in the second message frame. For example, the Soft AP may roughly classify the second device based on the capability information included in the second message frame. If the second message frame further includes a BandID field, the Soft AP may further classify the second device based on the BandID field.

[0047] According to embodiments of the present disclosure, there is no out-of-band interference between different frequency bands used to establish a BSS. For example, based on the principle that there is no out-of-band interference between the 2.4 GHz band and the 5 GHz band, or between the 2.4 GHz band and the 6 GHz band, a Soft AP can send beacon frames in both the 2.4 GHz band and the 5 GHz band to establish a BSS, or in both the 2.4 GHz band and the 6 GHz band to establish a BSS.

[0048] According to an embodiment of the present disclosure, Figure 2 The communication method shown may further include: in response to the second device supporting the 2.4 GHz frequency band and the 5 GHz frequency band, the first device and the second device establishing a basic service set in the 2.4 GHz frequency band and the 5 GHz frequency band respectively.

[0049] According to an embodiment of the present disclosure, Figure 2 The communication method shown may further include: in response to the second device supporting the 2.4 GHz frequency band and the 6 GHz frequency band, the first device and the second device establishing a basic service set in the 2.4 GHz frequency band and the 6 GHz frequency band respectively.

[0050] In one embodiment, the Soft AP classifies the frequency band information collected from pre-11be stations (e.g., HT stations, HE stations, and VHT stations) based on their supported frequency bands into one category, for example, supporting the 2.4 GHz, 5 GHz, or 6 GHz frequency bands. In this embodiment, the Soft AP classifies the pre-11be stations into either a first category of stations supporting both the 2.4 GHz and 5 GHz frequency bands or a second category of stations supporting both the 2.4 GHz and 6 GHz frequency bands. The Soft AP then establishes a BSS with the first category of stations in the 2.4 GHz and 5 GHz frequency bands, and with the second category of stations in the 2.4 GHz and 6 GHz frequency bands. For example, the Soft AP may receive a second message frame from a VHT station; based on the frequency band information included in the second message frame, classify the station as a first category of station; establish a BSS with the VHT station in the 2.4 GHz and 5 GHz frequency bands, and communicate with the VHT station via the 2.4 GHz BSS and the 5 GHz BSS. For example, the Soft AP may receive a second message frame from the HE site; based on the frequency band information included in the second message frame, classify it as a second type of site; establish a BSS with the HE site in the 2.4 GHz band and the 6 GHz band, and communicate with the HE site through the 2.4 GHz band BSS and the 6 GHz band BSS.

[0051] In one embodiment, the Soft AP categorizes the collected frequency band information supported by the EHT station into one category, for example, supporting the 2.4 GHz and 5 GHz bands, or the 2.4 GHz, 5 GHz, and 6 GHz bands. For example, the Soft AP may receive a second message frame from the EHT station; based on the frequency band information included in the second message frame, categorize the station as supporting the 2.4 GHz and 5 GHz bands; establish a BSS with the EHT station in the 2.4 GHz and 5 GHz bands, and communicate with the EHT station via the 2.4 GHz and 5 GHz BSSs. For example, the Soft AP may receive a second message frame from the EHT station; based on the frequency band information included in the second message frame, categorize the station as supporting the 2.4 GHz, 5 GHz, and 6 GHz bands; establish a BSS with the EHT station in the 2.4 GHz, 5 GHz, and 6 GHz bands, and communicate with the EHT station via the 2.4 GHz, 5 GHz, and 6 GHz BSSs. If three BSSs (2.4 / 5 / 6GHz) are established, simultaneous communication is possible in the 2.4GHz and 5GHz bands; simultaneous communication is possible in the 2.4GHz and 6GHz bands, and time division communication is possible in the 5GHz and 6GHz bands.

[0052] In one embodiment, Figure 2 The communication method may further include: in response to the first device and the second device establishing a basic service set in the 2.4 GHz frequency band, the 5 GHz frequency band, and the 6 GHz frequency band, performing communication according to the following manner:

[0053] The first device and the second device communicate simultaneously in the 2.4 GHz frequency band and the 5 GHz frequency band; or

[0054] The first device and the second device communicate simultaneously in the 2.4 GHz band and the 6 GHz band; or

[0055] The first device and the second device perform time-sharing communication in the 5 GHz frequency band and the 6 GHz frequency band.

[0056] In addition, although not shown, according to an embodiment of the present disclosure, Figure 2 The illustrated communication method may further include: establishing a basic service set (BSS) with the second device based on the number of basic service sets (BSSs) in each frequency band. In one embodiment, the Soft AP may determine the number of BSSs in each frequency band based on the frequency band information collected in step 220, and establish a BSS based on the number of BSSs in each frequency band. For example, if the first device and the second device have three overlapping basic service sets (OBSSs) in the 2.4 GHz band and two OBSSs in the 5 GHz band, the first device may choose to establish a BSS with the second device in the 5 GHz band.

[0057] In an exemplary embodiment of the present disclosure, the EHT station (and supporting the Soft AP function) establishes a BSS capable of simultaneous communication under different connections or time-sharing communication based on the Band ID information collected in step 210, specifically:

[0058] I. If the Soft AP classifies the frequency band information collected by pre-11be stations into one category, such as supporting the 2.4 GHz, 5 GHz, or 6 GHz bands; and classifies the frequency band information supported by EHT stations into one category, such as supporting the 2.4 GHz and 5 GHz bands, or the 2.4 GHz, 5 GHz, and 6 GHz bands; and based on the principle that there is no out-of-band interference between the 2.4 GHz and 5 GHz bands, or the 2.4 GHz and 6 GHz bands, the EHT station (that supports the Soft AP function) can send beacon frames in the 2.4 GHz and 5 GHz bands to establish a BSS, or send beacon frames in the 2.4 GHz and 6 GHz bands to establish a BSS;

[0059] II. Basic conditions for establishing a 2.4GHz, 5GHz, or 6GHz BSS

[0060] You can also establish BSSs based on the number of BSSs in each frequency band, but the primary principle is to establish two BSSs that do not interfere with each other (capable of receiving and transmitting simultaneously in two connections);

[0061] If three BSSs (2.4 / 5 / 6GHz) are established, the 2.4GHz and 5GHz bands or the 6GHz band can communicate simultaneously, while the 5GHz and 6GHz bands can use time division.

[0062] Figure 3 is a flowchart illustrating another communication method according to an example embodiment of the present disclosure. Figure 3 The communication method shown can be applied to Figure 1 Site 1 to Site 4 in (hereinafter, may be referred to as second devices).

[0063] Reference Figure 3 In step 310, a first message frame may be received. The first message frame may be determined and sent by a Soft AP. The first message frame may include information indicating that the first device sending the first message frame supports a soft access function, wherein the information indicating support for the soft access function is in an EHT capability information element of the first message frame.

[0064] In step 320, a second message frame may be sent. When the second device receives the first message frame from the first device and needs to access the first device, the second device may send a second message frame in response to the first message frame. The second message frame includes information about frequency bands supported by the second device located near the first device.

[0065] According to an embodiment, the frequency band information supported by the second device is included in the capability information of the second message frame. According to an embodiment, the capability information may include at least one of the following items:

[0066] High Throughput (HT) capability information;

[0067] Very High Throughput (VHT) capability information;

[0068] High-Efficiency (HE) capability information;

[0069] Extreme High Throughput (EHT) capability information.

[0070] According to an embodiment, the frequency band information supported by the second device is included in the frequency band identification field of the second message frame. The frequency band information of the second message frame in step 320 can be similar to that of reference Figure 2 For the sake of brevity, repeated descriptions of the described embodiments are omitted here.

[0071] In step 330, the first device establishes a basic service set (BSS) with the second device in different frequency bands. For example, the first device may classify the second device based on the frequency band information and, based on the classification result, send a beacon frame to the second device in the corresponding frequency band. After receiving the beacon frame, the second device sends an association request frame to the first device. The second device then feeds back an association response frame to the second device, thereby establishing the BSS.

[0072] In one embodiment, in response to the second device supporting the 2.4 GHz frequency band and the 5 GHz frequency band, the first device and the second device establish a basic service set in the 2.4 GHz frequency band and the 5 GHz frequency band respectively.

[0073] In one embodiment, in response to the second device supporting the 2.4 GHz frequency band and the 6 GHz frequency band, the first device and the second device establish a basic service set in the 2.4 GHz frequency band and the 6 GHz frequency band respectively.

[0074] In one embodiment, the first device and the second device establish a basic service set according to the number of basic service sets in each frequency band.

[0075] In step 340, communication may be performed. In one embodiment, in response to the first device and the second device establishing a basic service set in the 2.4 GHz band, the 5 GHz band, and the 6 GHz band, communication may be performed in the following manner:

[0076] The first device and the second device communicate simultaneously in the 2.4 GHz frequency band and the 5 GHz frequency band; or

[0077] The first device and the second device communicate simultaneously in the 2.4 GHz band and the 6 GHz band; or

[0078] The first device and the second device perform time-sharing communication in the 5 GHz frequency band and the 6 GHz frequency band.

[0079] exist Figure 3 In the steps shown, for the sake of simplicity, the reference Figure 2 The corresponding embodiments described are similar to those described above.
