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] 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, 5.8GHz and 6-7GHz frequency bands. For simultaneous communication between devices 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 supported by existing standards may also be supported.

[0005] In the Wi-Fi technology currently being studied, multi-connection communication is supported. For example, the access point (AP: Access Point) and station (STA: station) included in the current wireless communication system can be a multi-link device (MLD: multi-link device), that is, it supports the function of being able to send and / or receive simultaneously under multiple connections at the same time. Therefore, there can be multiple connections between the APMLD and the STA MLD.

[0006] In the existing standards, in order to improve the utilization of spectrum, spatial reuse (SR: spatial reuse) technology is introduced, for example, parameterized spatial reuse (PSR: parameterized spatial reuse) mechanism. However, the existing PSR mechanism only supports single connection applications and is not suitable for the above-mentioned multi-connection communication. Summary of the invention

[0025] It should be understood that when an element is referred to as being "connected" or "coupled" to another element, it may be directly connected or coupled to the other element, or there may be intermediate elements. In addition, "connected" or "coupled" as used herein may include wireless connections or wireless couplings.

[0026] 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.

[0027] Figure 1 is an exemplary diagram illustrating a wireless communication scenario.

[0028] 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, or can be connected to another Basic Service Set to form an Extended Service Set (ESS).

[0029] In a wireless communication environment, there may usually be multiple basic service sets (BSS), such as Figure 1 In the example of BSS 1 and BSS 2, each BSS may include an access point and one or more stations. Figure 1 In the example, BSS 1 includes AP1 and STA1, and BSS2 includes AP2 and STA2. However, it will be understood that Figure 1 The number of basic service sets and the number of access points and stations in each basic service set shown in FIG. 1 are merely exemplary, and the embodiments of the present disclosure are not limited thereto.

[0030] AP (e.g., AP1 and AP2) 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.

[0031] 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.

[0032] As examples, stations (e.g., STA1 and STA2) may include, but are not limited to, cellular phones, smart phones, 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.

[0033] In an exemplary embodiment of the present disclosure, AP and STA may be devices that support multiple connections, for example, they may be represented as AP MLD and STA MLD, respectively. For example only, AP MLD may represent an access point that supports multiple connection communication functions, and STA MLD may represent a station that supports multiple connection communication functions. For ease of description, Figure 1 In each BSS shown, an example is mainly shown in which one AP MLD communicates with one STA MLD under multiple connections, however, the example embodiments of the present disclosure are not limited thereto.

[0034] For example, in Figure 1 In the BSS1 shown, AP1 may also be represented as AP1 MLD, and STA1 may also be represented as STA1 MLD, and they may communicate under multiple connections. According to an embodiment, the multiple connections may be multiple connections at different frequencies, for example, connections at 2.4 GHz, 5 GHz, 6 GHz, etc., or may be several connections of the same or different bandwidths at various frequencies. In addition, multiple channels may exist under each connection. The description of BSS1 also applies to BSS2, and for the sake of simplicity, repeated descriptions are omitted here. In the following, for the sake of ease of description, AP and AP MLD may be used interchangeably, and STA and STA MLD may be used interchangeably.

[0035] When access points in multiple basic service sets are densely arranged in a wireless communication environment, there may be overlap in coverage between basic service sets (e.g., overlapping basic service sets (OBSS)), resulting in communication interference. Therefore, spatial reuse (SR) technology is introduced to improve communication efficiency and spectrum utilization.

[0036] The existing space reuse technology is only applicable to an environment where there is a single connection between the AP and the STA. In order to apply to the above-mentioned multi-connection communication, the embodiments of the present disclosure provide the communication method and communication device described below.

[0037] Figure 2 is a flowchart illustrating a communication method according to an embodiment. Figure 2 The communication method shown can be applied to an access point.

[0038] Reference Figure 2 In step 210, the first message frame may be determined. In the embodiment of the present disclosure, there may be many ways to determine the first message frame, for example, the AP may generate the first message frame according to at least one of the following conditions: network conditions, load conditions, hardware capabilities of the sending / receiving device, service type, and related protocol provisions; this embodiment of the present disclosure is not specifically limited to this. In the embodiment of the present disclosure, the AP may also obtain the first message frame from an external device, which is not specifically limited to this embodiment of the present disclosure.

[0039] According to an embodiment, the first message frame may include first information related to spatial multiplexing of multiple connections supported by the access point, wherein the first information is used for the access point to perform spatial multiplexing when exchanging data with the station.

[0040] According to an embodiment, the first information may include spatial multiplexing parameter set information (SR parameter set element), and its format may be as shown in Table 1 below.

[0041] Table 1. Format of spatial multiplexing parameter set

[0042]

[0043] In one embodiment, the format of the SR control field in Table 1 may be as shown in Table 2 below.

[0044] Table 2. Format of the SR control field

[0045]

[0046] It is understood that each element in Table 1 or Table 2 exists independently. These elements are exemplarily listed in the same table, but it does not mean that all elements in the table must exist at the same time as shown in the table. The value of each element is independent of the value of any other element in Table 1. Therefore, those skilled in the art can understand that the value of each element in Table 1 or Table 2 is an independent embodiment.

[0047] Referring to Table 1 and Table 2, when performing OBSS PD-based spatial reuse operation and PSR-based spatial reuse operation, the spatial reuse parameter set information can provide the information required by the station (STA).

[0048] Continue to refer to Figure 2 In step 220, a first message frame may be sent. The first message frame may be sent at different stages of communication between the access point and the station.

[0049] According to one embodiment of the present disclosure, the first message frame may be a beacon frame, that is, the step of sending the first message frame may be performed in the process of the access point broadcasting the beacon frame so that the station discovers and accesses the access point. The first message frame may carry the first information in various ways.

[0050] In one embodiment, the first message frame may include a reduced neighbor report information element, in which case the spatial multiplexing parameter set information (as shown in Tables 1 and 2) may be included in the reduced neighbor report information element. In addition, according to an embodiment, the reduced neighbor report information element may also include a multi-connection device (MLD) parameter subfield, which includes information such as an identifier of the multi-connection device and a connection identifier corresponding to each connection under the multi-connection device. Therefore, the spatial multiplexing parameter set information and the connection identifier may together indicate that spatial multiplexing is performed under the corresponding connection.

[0051] In another embodiment, the first message frame may directly include the newly defined spatial multiplexing parameter set information, which is different from the format shown in Table 1 and Table 2. In addition to the contents shown in Table 1 and Table 2, it may also include a connection identifier (link ID). For example, an additional subfield for indicating the connection identifier may be added in Table 1. That is, the first information may include the spatial multiplexing parameter set and the connection identifier (linkID) shown in Table 1 and Table 2, wherein the connection identifier information corresponds to multiple connections supported by the access point. In one example, each of the multiple connections corresponds to a connection identifier, that is, the multiple connections correspond one-to-one to the connection identifiers. However, this is merely exemplary, and the embodiments of the present disclosure are not limited thereto. For example, the first information may include a connection identifier corresponding to a connection that needs to be spatially multiplexed.

[0052] In another embodiment, the spatial multiplexing parameter set information may exist in the form of an MLD level, in which case the spatial multiplexing parameter set information is set to be the same in each of the multiple connections. In other words, in this case, since the same spatial multiplexing parameter set information is set in each connection, the connection identifier information may not be carried.

[0053] According to another embodiment of the present disclosure, the first message frame may be a multi-link probe response (ML (multi-link) probe response) frame. In this case, the step of sending the first message frame may be performed when the station has accessed the access point and multiple connections are further established between the access point and the station. For example, when the access point receives a request frame for establishing multi-link communication with the access point from the station, the access point may send an ML probe response frame to the station, and carry the first information (e.g., the spatial multiplexing parameter set information shown in Tables 1 and 2) in the ML probe response frame.

[0054] In this embodiment, the first message frame (e.g., ML detection response frame) may include a multi-link information element (MLelement), and the spatial multiplexing parameter set information is included in the multi-link information element. The multi-link information element may include an element identification field, a length field, an element identification extension field, a common information field, a perlink information field, etc. It will be understood that the various fields included in the multi-link information element are merely illustrative examples, not limitations of the present disclosure.

[0055] It will be understood that the types of first message frames described above are merely illustrative examples and are not limitations to the embodiments of the present disclosure.

[0056] According to an embodiment, the spatial multiplexing parameter set information may exist in the form of an MLD level, in which case the spatial multiplexing parameter set information may be included in the common information field of the multi-connection information element. According to another embodiment, the spatial multiplexing parameter set information may exist in the form of each connection (per link), in which case the spatial multiplexing parameter set information may be included in each connection configuration information field (per link profile).

[0057] According to an embodiment, the spatial multiplexing parameter set information may be included in a simplified neighbor report information element; or new spatial multiplexing parameter set information (which includes a connection identifier) ​​may be defined, i.e., the new spatial multiplexing parameter set information may be simply expressed as link ID+SR parameter set; or the spatial multiplexing parameter set information may exist at the MLD level, i.e., be set consistently under each connection.

[0058] According to an embodiment, the spatial multiplexing parameter set information may be included in the ML detection response frame, for example, in the multi-connection information element of the ML detection response frame. For example, if the spatial multiplexing parameter set information exists at the MLD level, it may be included in the public information field of the ML information element; for example, if the spatial multiplexing parameter set information may appear in the form of each connection (per link), it may be included in the per link profile field.

[0059] exist Figure 2 In the communication method shown, the access point provides the station with various parameter information required for OBSS PD-based spatial multiplexing operation and / or PSR-based spatial multiplexing operation by carrying spatial multiplexing parameter set information in the first message frame.

[0060] Figure 3 is a flow chart of a communication method according to an embodiment of the present disclosure. Figure 3 The communication method shown may be used to exchange capability information between an access point and a station.

[0061] Reference Figure 3 The station may determine a third message frame and send it to the access point, wherein the third message frame includes: third information for identifying the spatial multiplexing capability of the station. The access point may receive the third message frame from the station and thereby learn the information of the spatial multiplexing capability of the station.

[0062] According to an embodiment, the third information may include at least one of the following: a first identifier used to identify whether the parameterized spatial multiplexing responder is supported; and a second identifier used to identify whether the parameterized spatial multiplexing operation is supported.

[0063] In the embodiments of the present disclosure, there are many ways to determine the third message frame, for example, the site can generate the third message frame according to at least one of the following conditions: network conditions, load conditions, hardware capabilities of the sending / receiving device, service types, and related protocol regulations; the embodiments of the present disclosure are not specifically limited to this. In the embodiments of the present disclosure, the site can also obtain the third message frame from an external device, and the embodiments of the present disclosure are not specifically limited to this.

[0064] According to an embodiment, the third message frame may be a probe request, an association request, a re-association request, or a multi-connection probe request (MLprobe request) frame. It will be understood that the type of the third message frame described herein is merely an illustrative example and not a limitation of the embodiments of the present disclosure.

[0065] Continue to refer to Figure 3 The access point may determine a second message frame and send it to the station, wherein the second message frame may include: second information for identifying the spatial multiplexing capability of the access point. The station may receive the second message frame from the access point and thereby learn the information about the spatial multiplexing capability of the access point.

[0066] According to an embodiment, the second information may include at least one of the following: a third identifier used to identify whether the parameterized spatial multiplexing responder is supported; and a fourth identifier used to identify whether the parameterized spatial multiplexing operation is supported.

[0067] In the embodiment of the present disclosure, there are many ways to determine the second message frame, for example: the access point can generate the second message frame according to at least one of the following conditions: network conditions, load conditions, hardware capabilities of the sending / receiving device, service types, and related protocol regulations; this embodiment of the present disclosure is not specifically limited. In the embodiment of the present disclosure, the access point can also obtain the second message frame from an external device, which is not specifically limited in the embodiment of the present disclosure.

[0068] According to an embodiment, the second message frame may be a probe response frame, an association response frame, a re-association response frame, or an ML probe response frame, etc. It will be understood that the types of the second message frames described herein are merely illustrative examples and are not limitations of the embodiments of the present disclosure.

[0069] According to an embodiment, the second message frame and the third message frame may respectively carry the second information (third identifier and / or fourth identifier) ​​and the third information (first identifier and / or second identifier) ​​in the form of capability information elements.

[0070] In one embodiment, either the second message frame or the third message frame may include an extremely high-throughput (EHT) capability information element, and the second information (third identifier and / or fourth identifier) ​​may be included in the EHT capability information element of the second message frame, and the third information (first identifier and / or second identifier) ​​may be included in the EHT capability information element of the third message frame.

[0071] It will be understood that the “third identifier and the fourth identifier” of the second information or the “first identifier and the second identifier” of the third information may be included in different subfields in the EHT capability information element or included in different capability information. For example, the EHT capability information element may include an EHT MAC capability information element and an EHT PHY capability information element. For the third information, the first identifier may be included in the EHT MAC capability information element of the third message frame, and the second identifier may be included in the EHT PHY capability information element of the third message frame. For the second information, the third identifier may be included in the EHT MAC capability information element of the second message frame, and the fourth identifier may be included in the EHT PHY capability information element of the second message frame. However, it will be understood that this is merely exemplary and the present disclosure is not limited thereto. For example, the “third identifier and the fourth identifier” of the second information or the “first identifier and the second identifier” of the third information may be included in the same subfield in the EHT capability information element.

[0072] In another embodiment, either the second message frame and the third message frame may include a multi-connection information element (ML element). For the third information, the first identifier and / or the second identifier may be included in the multi-connection information element of the third message frame. For the second information, the third identifier and / or the fourth identifier may be included in the multi-connection information element of the second message frame.

[0073] According to an embodiment, the first identifier and the third identifier may be represented as a PSR responder subfield in the EHT MAC capability information element, and a detailed description thereof may refer to Table 3 below.

[0074] Table 3. Description of PSR Responder

[0075]

[0076] In an embodiment, the second identifier and the fourth identifier may be represented as a PSR-based SR Support subfield in the EHT PHY capability information element, and a detailed description thereof may be referred to as shown in Table 4 below.

[0077] Table 4. Description of PSR-based SR Support

[0078]

[0079] according to Figure 3According to the communication method shown, the AP can notify the site of the AP's spatial multiplexing capability information through the second information carried in the second message frame (i.e., the third identifier and / or the fourth identifier), and the site can notify the AP of the site's spatial multiplexing capability information through the third information carried in the third message frame (i.e., the first identifier and / or the second identifier).

[0080] In addition, the second information and the third information may be referred to as a spatial multiplexing (SR) subfield. According to an embodiment of the present disclosure, the SR subfield may be defined as an MLD level, which may be included in an EHT capability information element or in a multi-connectivity information element.

[0081] According to an embodiment, the SR subfield may be present in the EHT capability information element, and its setting may be as shown in Table 3 and Table 4 above.

[0082] According to an embodiment, the SR subfield may exist in the multiple connection information element, for example, may be identified using the common information subfield of the multiple connection information element.

[0083] For the manner in which the SR subfield exists in the EHT capability information element and the manner in which the SR subfield exists in the multi-connection information element, the station (e.g., EHT MLD STA) may encapsulate it in a probe request frame, an association request frame, a reassociation request frame, or an ML probe request frame; the access point (e.g., EHT MLD AP) may encapsulate it in a probe response frame, an association response frame, a reassociation response frame, or an ML probe response frame.

[0084] Although in Figure 3 , the station determines the third message frame and sends it to the access point, and the access point determines the second message frame and sends it to the station, but these two operations do not necessarily exist at the same time. In one embodiment, the access point may have the spatial multiplexing capability by default (for example, during hardware manufacturing or software design), and the station may know in advance that the access point itself has the spatial multiplexing capability. Therefore, the access point may not send the second message frame to the station, that is, Figure 3 In another embodiment, the station may have the spatial multiplexing capability by default (for example, during hardware manufacturing or software design), and the access point may know in advance that the station itself has the spatial multiplexing capability. Therefore, the station may not send the third message frame to the station, that is, in Figure 3 The actions performed by the site are omitted.

[0085] In addition, although Figure 2 and Figure 3 The communication method according to the embodiment of the present disclosure is shown separately, but the two can be combined. For example, you can first execute Figure 3The communication method shown in the figure enables the access point and the station to exchange spatial multiplexing capability information and other capability information; then execute Figure 2 The communication method shown in the figure enables the access point to allocate parameter information required for spatial multiplexing to the station. However, such a communication method is only exemplary and may be used for Figure 2 and Figure 3 The various steps shown in the figure may be changed, and some of the operations may be performed in parallel.

[0086] In addition, the communication method according to the embodiment of the present disclosure may omit Figure 3 In the communication method shown, for example, when both the access point and the station have the spatial multiplexing capability information by default, there is no need to interact with the spatial multiplexing capability information in advance, so the communication method can be omitted. Figure 3 The communication method shown.

[0087] according to Figure 2 and Figure 3 The communication method described can apply spatial reuse technology under multiple connections to improve spectrum utilization efficiency and system throughput.

[0088] Figure 4 is a flow chart illustrating another communication method according to the present disclosure. Figure 4 The communication method shown can be applied to the site.

[0089] Reference Figure 4 In step 410, a first message frame may be received, for example, the station may receive the first message frame from the access point, wherein the first message frame includes: first information related to spatial multiplexing of multiple connections supported by the access point, wherein the first information is used for spatial multiplexing between the station and the access point during data interaction.

[0090] According to an embodiment, the first information may include: spatial multiplexing parameter set information. The spatial multiplexing parameter set information may be as shown in Table 1 and Table 2 above. For the sake of simplicity, repeated descriptions are omitted here.

[0091] According to an embodiment, the first message frame may include: a reduced neighbor report information element, wherein the spatial multiplexing parameter set information is included in the reduced neighbor report information element.

[0092] According to an embodiment, the first information may further include: connection identification information, wherein the connection identification information corresponds to the plurality of connections.

[0093] According to an embodiment, the spatial multiplexing parameter set information is set to be the same in each of a plurality of connections existing between the station and the access point.

[0094] According to an embodiment, the first message frame may include: a multiple connection information element, wherein the spatial multiplexing parameter set information is included in the multiple connection information element.

[0095] According to an embodiment, the multiple connection information element includes a common information field, wherein the spatial multiplexing parameter set information is included in the common information field.

[0096] According to an embodiment, the multiple connection information element may include: each connection configuration information field, wherein the spatial multiplexing parameter set information is included in each connection configuration information field.

[0097] In step 420, the station may perform a communication operation based on the first information. For example, the station may adjust the transmit power based on the spatial multiplexing parameter set information to perform spatial multiplexing.

[0098] In addition, although not shown, Figure 4 The communication method shown may also include: receiving a second message frame, wherein the second message frame includes: second information for identifying the spatial multiplexing capability of the access point.

[0099] In addition, although not shown, Figure 4 The communication method shown may further include: sending a third message frame, wherein the third message frame includes: third information for identifying the spatial multiplexing capability of the site.

[0100] According to an embodiment, any one of the second information and the third information may include at least one of the following:

[0101] Identification information used to identify whether the responder supports parameterized spatial multiplexing;

[0102] Identification information used to indicate whether parameterized spatial multiplexing operations are supported.

[0103] The above two identification information may be similar to the descriptions in Table 3 and Table 4 above. For the sake of brevity, the description of repetition is omitted here.

[0104] In addition, the identification information included in any one of the second information and the third information may be referred to as a spatial multiplexing (SR) subfield. According to an embodiment of the present disclosure, the SR subfield may be defined as an MLD level, which may be included in an EHT capability information element or in a multi-connection information element.

[0105] According to an embodiment, the SR subfield may be present in the EHT capability information element, and its setting may be as shown in Table 3 and Table 4 above.

[0106] According to an embodiment, the SR subfield may exist in the multiple connection information element, for example, may be identified using the common information subfield of the multiple connection information element.

[0107] For the manner in which the SR subfield exists in the EHT capability information element and the manner in which the SR subfield exists in the multi-connection information element, the station (e.g., EHT MLD STA) may encapsulate it in a probe request frame, an association request frame, a reassociation request frame, or an ML probe request frame; the access point (e.g., EHT MLD AP) may encapsulate it in a probe response frame, an association response frame, a reassociation response frame, or an ML probe response frame.

[0108] According to an embodiment, any one of the second message frame and the third message frame may include: a very high throughput capability information element, wherein at least one of the above two identification information may be included in the very high throughput capability information element.

[0109] According to an embodiment, any one of the second message frame and the third message frame may include: a multiple connection information element, wherein at least one of the above two identification information may be included in the multiple connection information element.
