[0025] Figure 1 is an exemplary diagram illustrating a communication scenario under a multi-connection.
[0026] In a wireless local area network, a basic service set (BSS) can be formed by an AP and one or more non-AP STA devices in communication 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).
[0027] An AP is a wireless switch for a wireless network and is also the core of the wireless network. An AP device can be used as a wireless base station and is mainly used as a bridge connecting a wireless network and a wired network. With such an access point (AP), wired and wireless networks can be integrated.
[0028] An AP can include software applications and / or circuitry to enable other types of nodes in a wireless network to communicate with the wireless network both externally and internally through the AP. In some examples, the AP can be a terminal device or a network device equipped with a Wi-Fi (Wireless Fidelity) chip, for example.
[0029] A non-AP STA device can 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, and the like, for example.
[0030] In example embodiments of the present disclosure, an AP and a non-AP STA device can support multi-connected devices, which can be denoted as an AP MLD and a non-AP STA MLD, respectively, for example. For ease of description, hereinafter, an example in which one AP MLD and one non-AP STA MLD communicate under multi-connection will be mainly described, however, example embodiments of the present disclosure are not limited thereto.
[0031] In Figure 1 , an AP MLD can represent an access point supporting a multi-connection communication function, and a non-AP STA MLD can represent a non-access point device supporting a multi-connection communication function, for example only. Referring to Figure 1 , an AP MLD can operate under three connections, such as AP1, AP2, and AP3 as shown in Figure 1 , and a non-AP STA MLD can also operate under three connections, such as non-AP STA 1, non-AP STA 2, and non-AP STA 3 as shown in Figure 1 Figure 1 In the example shown in FIG. 1, it is assumed that AP1 communicates with non-AP STA1 through a corresponding first connection Link 1, and similarly, AP2 and AP3 communicate with non-AP STA2 and non-AP STA3 through second and third connections Link 2 and 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 the same or different bandwidths at 2.4 GHz. In addition, there can be multiple channels under each connection. However, it should be understood that, Figure 1 The communication scenario shown in FIG. 1 is only exemplary, and the inventive concept is not limited thereto. For example, there can be fewer or more connections between the AP MLD and the non-AP STA MLD, the AP MLD can be connected to multiple non-AP STA MLDs, or under each connection, the AP can communicate with multiple other types of stations.
[0032] In the current communication system, there can be stations supporting two functions: EMLSR (enhanced-multilink single radio) and EMLMR (enhanced-multilink multi-radio), where EMLSR refers to a non-AP STA MLD that can only communicate with an AP MLD under one connection at a time and perform channel listening under multiple connections, and EMLMR refers to a non-AP STA MLD that can communicate with an AP MLD under multiple connections at a time and perform channel listening under multiple connections. In the following, EMLSR is mainly taken as an example for description, however, it will be understood that embodiments of the disclosure are not limited thereto, for example, the methods described in the disclosure can also be applied to EMLMR.
[0033] Before the AP MLD and the non-AP STA MLD exchange data, the non-AP STA MLD receives parameters negotiated by the AP MLD for data exchange under each connection, such as the number of spatial streams, MCS (or data rate of non-HT PPDU), PPDU type, and frame type, etc.
[0034] Although some parameters are defined, the behavior of the AP MLD and the non-AP STA MLD (which can be collectively referred to as STA MLD (station multi-link device)) is not defined, so the EMLSR mechanism cannot be applied. Embodiments of the disclosure improve the communication mode of the STA MLD so that the EMLSR mechanism can be applied.
[0035] Figure 2 is a flowchart illustrating a communication method according to an example embodiment. Figure 2 The illustrated communication method can be applied to a multi-connection device, for example, can be applied to a non-AP STA MLD.
[0036] Referring to Figure 2 In step 210, a first message frame can be determined. In an embodiment of the present disclosure, there can be many ways to determine the first message frame, for example: the non-AP STA MLD can generate the first message frame according to at least one of the following: network conditions, load conditions, hardware capabilities of the transmitting / receiving device, traffic types, relevant protocol provisions; the present embodiment of the disclosure does not make specific limitations on this. In an embodiment of the present disclosure, the non-AP STA MLD can also obtain the first message frame from an external device, and the present embodiment of the disclosure does not make specific limitations on this.
[0037] According to an embodiment, the first message frame can include first information about EMLSR operation. Specifically, the first information is used to identify that the multi-connection device performs enhanced multi-link single radio communication (EMLSR) operation under at least part of the multiple connections. Wherein, the multiple connections refer to multiple connections that the multi-connection device (for example, non-AP STA MLD) can support, for example, Figure 1 The illustrated Link 1 to Link 3.
[0038] According to an embodiment of the present disclosure, the first message frame can be a probe request frame, an association request frame, a Re-association request frame, or a multi-link probing request (ML probing request) frame, etc.
[0039] In one embodiment, the first information included in the first message frame can have the format as shown in Table 1 below.
[0040] Table 1. Format of first information
[0041]
[0042] Referring to Table 1, the first information can include: connection identifiers corresponding to at least part of the connections used to perform EMLSR operation, i.e., connection identifier 1 to connection identifier n (n is an integer greater than or equal to 1) in Table 1. Link ID 1 to Link ID n identify that these connections are activated, so that listening or transmission can be performed under these links. For example, referring to Figure 1If the EMLSR operation can be performed under the first connection Link 1 and the third connection Link 3, the first information shown in Table 1 can include connection identifiers corresponding to the first connection Link 1 and the third connection Link 3, respectively, i.e., the first connection Link 1 and the third connection Link 3 are activated for listening or transmission. However, the embodiment in which the information about the connection used for performing the EMLSR operation is carried in the first information is not limited thereto. For example, in another embodiment, the first information can include state identifiers corresponding to all the multiple connections that the multi-connection device (e.g., non-AP STA MLD) can support, respectively. For example, referring to Figure 1 Assuming that the non-AP STA MLD can support 3 connections and can perform the EMLSR operation under the first connection Link 1 and the third connection Link 3, "101" can be included in the first information, three bits for indicating the states of the three connections, respectively, the bit set to "1" can represent that it can be used for performing the EMLSR operation, and the bit set to "0" can represent that it can be used for performing the EMLSR operation. It will be understood that the specific numerical values used herein are only exemplary illustrations, not limitations of the present disclosure.
[0043] Referring to Table 1, the first information can include switch delay identification information indicating the switching delay from one connection to another connection for data transmission. That is, when the non-AP STA MLD communicates with the AP MLD, if one connection cannot meet the communication requirement, it needs to switch to another connection for communication, and there will be a delay when switching to another connection. In one embodiment, when the switch delay identification (Switch delay) in Table 1 is set to 0, it can be identified that the delay is 32us (microsecond); when the switch delay identification in Table 1 is set to 1, it can be identified that the delay is 64us. It will be understood that the specific numerical values used herein are only exemplary illustrations, not limitations of the present disclosure, for example, a plurality of bits can be used to represent the switch delay identification, so that a plurality of different delay values can be identified, for example, 32us, 64us, 48us, etc.
[0044] In one embodiment, the delay of switching under each connection can be consistent. However, the present disclosure is not limited thereto, and Table 1 can also include a plurality of delay identifications to define the delay values of switching to each connection as different values.
[0045] In one embodiment, the first message frame can include a multi-link information element (ML: multi-link Information element), and the first information (as shown in Table 1) can be carried in the first message frame in the form of the multi-link information element. That is, the first information can be contained in the multi-link information element.
[0046] According to embodiments, the first message frame can comprise an ML information element which identifies under which links the non-AP STA MLD can perform EMLSR operation, which can be as shown in Table 1. In Table 1, Link ID identifies the links that are activated and can be used for listening or transmitting, Switch delay identifies the delay for switching to transmit data on another link, the delay for switching under each link can be consistent, or the delay for switching to each link can be defined as having different switching delay values.
[0047] In an embodiment, the first message frame can further comprise an identification bit indicating that the multi-link device (e.g., the non-AP STA MLD) supports EMLSR. For example, the first message frame can comprise an extreme high-throughput (EHT) capabilities information element, and the identification bit indicating that the non-AP STA MLD supports EMLSR can be included in the EHT capabilities information element. For example, the EHT capabilities information element can be an EHT MAC capabilities information element or an EHT PHY capabilities information element. That is, the identification bit indicating that the non-AP STA MLD supports EMLSR can be included in the EHT MAC capabilities information element or the EHT PHY capabilities information element.
[0048] According to embodiments, the non-AP STA MLD can use a field in an EHT capabilities information element to identify that it supports EMLSR (e.g., using one bit), and the EHT capabilities information element can be EHT MAC capabilities or EHT PHY capabilities. The non-AP STA MLD can include the EHT capabilities information element in a probe request frame, an (re)association request frame, or an ML probe request frame.
[0049] Continuing with reference to Figure 2 In step 220, the first message frame can be transmitted. For example, the non-AP STA MLD can transmit the first message frame carrying the first information and the identification bit indicating support for EMLSR to the AP MLD for further communication with the AP MLD, e.g., in the manner of EMLSR.
[0050] It will be understood that Figure 2 The steps included in the communication method shown are only exemplary, and embodiments of the present disclosure are not limited thereto.
[0051] In another embodiment, Figure 2 The illustrated communication method can further include receiving a second message frame. For example, the second message frame is received from the AP MLD. According to an embodiment, the second message frame can include parameter information required for performing the EMLSR operation. That is, the AP MLD can configure the non-AP STA MLD with parameters required for the EMLSR operation. In one embodiment, in response to the first message frame transmitted by the non-AP STA MLD in step 220, the AP MLD can transmit the second message frame to the non-AP STA MLD, thereby configuring the non-AP STA MLD with parameters required for the EMLSR operation.
[0052] According to an embodiment, the parameter information can include at least one of:
[0053] information on spatial streams (e.g., the number of spatial streams);
[0054] information on a modulation and coding scheme (MCS) (e.g., the index of the MCS);
[0055] information on a physical layer protocol data unit (PPDU) (e.g., the type of the PPDU);
[0056] information on a frame type.
[0057] It will be understood that the parameter information illustrated herein is only an exemplary illustration, and is not a limitation on the present disclosure.
[0058] In one embodiment, the AP MLD can configure the non-AP STA MLD with the same parameters in the second message frame. In the case where the parameter information is set to be different under different connections, the second message frame further includes a connection identification corresponding to the parameter information. That is, in this case, the second message frame can carry the parameter information as described above in the form of an information element.
[0059] In another embodiment, the AP MLD can configure the non-AP STA MLD with different parameters in the second message frame, in which case the second message frame can not only include the parameter information under each connection, but also include a connection identification corresponding to the parameter information.
[0060] According to embodiments, the AP MLD can configure the same parameters (under each connection) for the non-AP STA MLD, or configure different parameters under different connections. For example, the parameters can be configured in the form of an information element, and the specific parameters can be: spatial streams, MCS index, PPDU type, etc. If the parameters are inconsistent under each connection, the Link ID needs to be taken as an identifier together with the parameters.
[0061] In embodiments of the present disclosure, the transmission of the first message frame and the second message frame can be performed under any activated connection between the non-AP STA MLD and the AP MLD, for example, the first message frame and the second message frame can be transmitted under any activated connection of Link 1 to Link 3 shown in the figure. Figure 1
[0062] Referring to Figure 2 The described communication method can enable the application of the EMLSR mechanism, and improve the utilization efficiency of the spectrum and the system throughput.
[0063] Figure 3 is a flowchart of another communication method according to embodiments of the present disclosure. Figure 3 The communication method shown in the figure can be applied to an access point, for example, an AP MLD.
[0064] Referring to Figure 3 In step 310, a first message frame can be received. According to embodiments, the first message frame can include first information, and the first information is used to identify that a multi-connection device (for example, a non-AP STA MLD) that transmits the first message frame performs an enhanced multi-connection single radio communication (EMLSR) operation under at least part of the connections in the multiple connections.
[0065] According to embodiments, the first information can include a connection identifier corresponding to at least part of the connections used to perform the EMLSR operation.
[0066] According to embodiments, the first information can include switching delay identifier information indicating switching from one connection to another connection for data transmission.
[0067] According to embodiments, the first information can be carried in the first message frame in the form of a multi-connection information element.
[0068] The first message frame and the first information in step 310 can be similar to the description with reference to Figure 2 and Table 1, and repeated descriptions are omitted here for brevity.
[0069] According to an embodiment, the first message frame can further include an identification bit indicating that the multi-connection device sending the first message frame supports EMLSR. According to an embodiment, the identification bit can be included in an Extremely High Throughput (EHT) capability information element of the first message frame. The identification bit can be similar to that described with reference to Figure 2 for brevity.
[0070] In step 320, communication can be performed based on the first message frame. For example, an EMLSR operation can be performed under the corresponding connection.
[0071] Further, although not shown, the communication method shown in Figure 3 may further include transmitting a second message frame, wherein the second message frame includes parameter information required for performing the EMLSR operation. That is, the AP MLD can configure the parameter information for the non-AP STA MLD by transmitting the second message frame to the non-AP STA MLD. In one embodiment, the AP MLD can transmit the second message frame to the non-AP STA MLD in response to receiving the first message frame from the non-AP STA MLD, thereby configuring the non-AP STA MLD with parameters required for the EMLSR operation.
[0072] According to an embodiment, the parameter information included in the second message frame can include at least one of:
[0073] information on spatial streams;
[0074] information on modulation and coding strategies;
[0075] information on physical layer protocol data units;
[0076] information on frame types.
[0077] In one embodiment, the AP MLD can configure the same parameters for the non-AP STA MLD in the second message frame, in which case the second message frame can carry the parameter information as described above in the form of an information element.
[0078] In another embodiment, the AP MLD can configure different parameters for the non-AP STA MLD in the second message frame. In the case where the parameter information is set to be different under different connections, the second message frame further includes a connection identification corresponding to the parameter information. That is, in this case, the second message frame can not only include the parameter information under each connection, but also include the connection identification corresponding to the parameter information.
[0079] Referring to Figure 3The described communication method can enable the EMLSR mechanism to be applied, improve the spectrum utilization efficiency and system throughput.
