Description

[0001] This application is a divisional application of the PCT international patent application PCT / CN2020 / 137763 with an application date of December 18, 2020, which entered the Chinese national phase with Chinese patent application number 202080103300.6 and the invention name “Wireless Communication Method, Terminal Equipment and Network Equipment”. Technical Field

[0002] The embodiments of the present application relate to the field of communications, and more specifically, to a wireless communication method, a terminal device, and a network device. Background Art

[0003] Multi-link (ML) related standards include ML discovery, ML establishment, link management, ML block reply, ML energy saving, etc. The main research point of link management is the mapping of traffic identifier (TID) to link (TID-to-link). The standard requires that each TID must be mapped to a link or a set of links to ensure that the service flow corresponding to the TID can be transmitted.

[0004] Currently, changes to the mapping information of traffic identifiers to links are obtained through negotiation of the Multi-link Device (MLD), including three situations: 1. If the link set responded by the receiving end is the same as the link set provided by the sending end, the mapping result of the traffic identifier to the link is the link set provided by the sending end, and the negotiation is considered successful. 2. If the receiving end provides a set of backup link sets, and the backup link set is a non-empty subset of the link set provided by the sending end, the mapping result is the backup link set provided by the receiving end, and the negotiation is considered successful. 3. If the link set responded by the receiving end is an empty set, the original mapping of traffic identifiers to links will be retained, and the negotiation is considered failed.

[0005] In summary, the current mapping information changes of traffic identifiers to links all adopt the request / response negotiation mode. However, the mapping scenarios of traffic identifiers to links are diverse. In some specific scenarios, the negotiation mode may not be needed. If this negotiation mode is used, it will cause the problem of excessive signaling overhead. Summary of the invention

[0048] The following will describe the technical solutions in the embodiments of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. For the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0049] As mentioned above, the current mapping information change of traffic identifiers to links is obtained through MLD negotiation, including the above three situations. In fact, these three situations are applicable to the expansion, compression and switching scenarios of the negotiation of mapping of traffic identifiers to links. The following describes the application of the above three situations in three scenarios:

[0050] Figure 1 What is provided is a schematic diagram of an extended scenario of negotiation of mapping traffic identifiers to links, such as Figure 1 As shown, the original mapping includes: mapping of TID4 to 5 GHz link, and the mapping provided by MLD1 includes: mapping of TID4 to 2.4 and 5 GHz links, MLD2 agrees with the mapping provided by MLD1, that is, the mapping responded by MLD2 includes: mapping of TID4 to 2.4 and 5 GHz links, based on this, the mapping negotiation is successful, and the mapping after the negotiation includes: mapping of TID4 to 2.4 and 5 GHz links.

[0051] Figure 2 Provided is another extended scenario diagram of the negotiation of mapping traffic identifiers to links, such as Figure 2 As shown, the original mapping includes: mapping of TID4 to 5 GHz link, and the mapping provided by MLD1 includes: mapping of TID4 to 2.4 and 5 GHz links. MLD2 does not agree to map TID4 to the 2.4 GHz link, that is, the mapping responded by MLD2 includes: mapping of TID4 to 5 GHz link. In this case, the mapping is deemed to be successfully negotiated, and the mapping after negotiation includes: mapping of TID4 to 5 GHz link.

[0052] Figure 3 What is provided is a schematic diagram of a compressed scenario for negotiating the mapping of traffic identifiers to links, such as Figure 3 As shown, the original mapping includes: mapping of TID4 to 2.4 and 5 GHz links, and the mapping provided by MLD1 includes: mapping of TID4 to 5 GHz link. MLD2 agrees with the mapping provided by MLD1, that is, the mapping responded by MLD2 includes: mapping of TID4 to 5 GHz link. Based on this, the mapping negotiation is successful, and the mapping after the negotiation includes: mapping of TID4 to 5 GHz link.

[0053] Figure 4 What is provided is a schematic diagram of a switching scenario for negotiating the mapping of traffic identifiers to links, such as Figure 4 As shown, the original mapping includes: mapping of TID4 to 5 GHz link, and the mapping provided by MLD1 includes: mapping of TID4 to 6 GHz link, MLD2 agrees with the mapping provided by MLD1, that is, the mapping responded by MLD2 includes: mapping of TID4 to 6 GHz link, based on this, the mapping negotiation is successful, and the mapping after the negotiation includes: mapping of TID4 to 6 GHz link.

[0054] Figure 5 Provided is another switching scenario diagram of the negotiation of mapping traffic identifiers to links, such as Figure 5 As shown, the original mapping includes: mapping of TID4 to 5GHz link, and the mapping provided by MLD1 includes: mapping of TID4 to 6GHz link, MLD2 disagrees with the mapping provided by MLD1, that is, the link set responded by MLD2 is an empty set, based on this, the mapping negotiation fails, and therefore, the original mapping remains unchanged, that is, including: mapping of TID4 to 5GHz link.

[0055] Figure 6 Provided is another switching scenario diagram of the negotiation of mapping traffic identifiers to links, such as Figure 6As shown, the original mapping includes: mapping of TID4 to the 5 GHz link, and the mapping provided by MLD1 includes: mapping of TID4 to the 2.4 and 6 GHz links. MLD2 disagrees to map TID4 to the 2.4 GHz link. The mapping responded by MLD2 includes: mapping of TID4 to the 6 GHz link. Based on this, the mapping negotiation is deemed successful, and the mapping after the negotiation includes: mapping of TID4 to the 6 GHz link.

[0056] As mentioned above, the current mapping of traffic identifiers to links adopts the request / response negotiation mode. However, in some specific scenarios, the sender can decide the mapping scheme, and the receiver only needs to collect the mapping scheme. For details, see the following example:

[0057] Exemplarily, when a site multi-link device (non-AP MLD) has a large number of service flows corresponding to a certain uplink TID, it needs to try its best to provide a dedicated link set for the uplink TID. In this case, the site multi-link device initiates a remapping request to remove other uplink TIDs on at least one original link mapped by the TID. At this time, the link set corresponding to each TID in the updated mapping of traffic identifiers to links is a non-empty subset of the original mapping link set of each TID, corresponding to a compression scenario. In this case, for the site multi-link device, it hopes that the access point multi-link device will directly accept the remapping request.

[0058] For example, from the perspective of improving system performance, the access point multi-link device (AP MLD) has the link state information of all sites associated with it, so a better mapping result of traffic identifiers to links can be obtained through a certain algorithm, and the mapping result can also meet the transmission requirements of the site multi-link device. In this case, for the access point multi-link device, it hopes that the site multi-link device will directly accept this better mapping result.

[0059] In the above scenario, or other possible scenarios, if the receiving end still replies with a response message, the signaling overhead will increase.

[0060] In order to solve the above technical problems, the present application adopts a mandatory mode, which instructs the receiving end not to reply with response information to reduce signaling overhead.

[0061] Combine the following Figure 7 , the architecture of the communication system in this application is described.

[0062] For example, Figure 7 This is a schematic diagram of the architecture of a communication system provided in an embodiment of the present application. Figure 7, including a site multi-link device 710 and an access point multi-link device 720, and at least two links may exist between the site multi-link device 710 and the access point multi-link device 720 for wireless communication. Optionally, the communication system may include multiple site multi-link devices 710, and may also include multiple access point multi-link devices 720, which is not limited in the embodiment of the present application.

[0063] It should be understood that the site multi-link device 710 may include: at least one station (Station, STA), therefore, the site multi-link device 710 may be understood as a logical entity, wherein: Figure 7 It is exemplarily shown that the station multi-link device 710 includes two STAs.

[0064] It should be understood that the access point multi-link device 720 may include: at least one access point (Access Point, AP), therefore, the access point multi-link device 720 can be understood as a logical entity, wherein, Figure 7 It is exemplarily shown that the access point multi-link device 720 includes two APs.

[0065] It should be understood that there may be one link between one AP and one STA.

[0066] Optionally, Figure 7 The communication system shown may also include other network entities such as a mobility management entity (Mobility Management Entity, MME), an access and mobility management function (Access and Mobility Management Function, AMF), etc., which is not limited in the embodiments of the present application.

[0067] It should be understood that the terms "system" and "network" are often used interchangeably herein.

[0068] Optionally, the communication system in the embodiment of the present application can be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, or a standalone (SA) networking scenario.

[0069] Optionally, the embodiments of the present application may be applied to unlicensed spectrum or to licensed spectrum, wherein the unlicensed spectrum may also be considered as a shared spectrum, and the licensed spectrum may also be considered as a non-shared spectrum.

[0070] It should be understood that the site multi-link device and the access point multi-link device need to first perform multi-link discovery, multi-link establishment, and mapping of traffic identifiers to links. These three parts are described below:

[0071] Step 1: Multi-link discovery

[0072] The basic goal of multi-link discovery is that the site multi-link device can obtain information about the access point multi-link device and all the links it supports by receiving beacon frames or probe response frames from any subordinate AP of the access point multi-link device. Its essence is a multi-link scanning process, namely, multi-link discovery.

[0073] After the multi-link discovery phase is completed, the site multi-link device obtains complete or partial information of the APs affiliated with the access point multi-link device.

[0074] Step 2: Multi-link establishment

[0075] The basic goal of multi-link establishment is for the site multi-link device and the access point multi-link device to exchange the complete information of their respective attached STA and AP, and complete the multi-link establishment according to their respective capability information. Its essence is the multi-link association process, that is, multi-link establishment.

[0076] The following steps 2.1 and 3 respectively describe the process of establishing the traffic identifier-to-link mapping information between the site multi-link device and the access point multi-link device in the non-default mode of traffic identifier-to-link mapping.

[0077] The default mode of mapping traffic identifiers to links is that all traffic identifiers are mapped to all established links. If a non-default mode is used during initialization, a preliminary negotiation of mapping traffic identifiers to links is required between the site multi-link device and the access point multi-link device.

[0078] Step 2.1 (optional method 1 for establishing mapping of traffic identifiers to links): mapping information of traffic identifiers to links is established in the multi-link establishment phase.

[0079] Optionally, the mapping information of traffic identifier to link can be included in the multi-link establishment phase. A specific implementation is to place the mapping information of traffic identifier to link as a field in the ML information element of the association request / response frame used in the multi-link establishment phase. Figure 8 A schematic diagram of the ML information element provided in the embodiment of the present application, such as Figure 8 As shown, the ML information element includes mapping information from traffic identifiers to links.

[0080] Step 3 (optional method 2 for establishing mapping of traffic identifiers to links): the multi-link establishment phase and the traffic identifier-to-link mapping information establishment phase are independent.

[0081] Optionally, the mapping information from the traffic identifier to the link may be included in a certain independent stage, in which the mapping information from the traffic identifier to the link is included using the information element of the corresponding management frame.

[0082] Through the above steps, the mapping information from traffic identifier to link between the site multi-link device and the access point multi-link device is established.

[0083] This application will focus on updating the mapping information of traffic identifiers to links. The technical solution of this application will be described in detail below:

[0084] Example 1

[0085] Fig. 9 An interactive flow chart of a wireless communication method provided in an embodiment of the present application, such as Fig. 9 As shown, the method includes:

[0086] S910: The site multi-link device updates first mapping information.

[0087] S920: The site multi-link device generates a first indication message.

[0088] S930: The site multi-link device sends a first indication message to the access point multi-link device.

[0089] S940: The access point multi-link device updates the second mapping information according to the updated first mapping information.

[0090] It should be understood that the first mapping information is mapping information from a traffic identifier to an uplink at the site multi-link device side.

[0091] It should be understood that the traffic identifier involved in the first mapping information may be all uplink traffic identifiers of the site multi-link device, or may be an uplink traffic identifier of the corresponding mapping information to be updated, and the present application does not impose any limitation on this.

[0092] It should be understood that the traffic identifier involved in the first mapping information may be one or more. If it is one, then the first mapping information is the mapping information of the traffic identifier to the uplink on the site multi-link device side. If it is more than one, then the first mapping information is the mapping information of these multiple traffic identifiers to the uplink on the site multi-link device side.

[0093] It should be understood that a traffic identifier may correspond to or be mapped to at least one link. For example, TID1 may be mapped to link 1 and link 2 , and TID2 may be mapped to link 1 .

[0094] It should be understood that the site multi-link device can update the first mapping information in the above compression scenario.

[0095] For example, Fig.10 A schematic diagram of updating the mapping information of the traffic identifier to the link provided in the embodiment of the present application, such as Fig.10 As shown in the figure, there are two links between the site multi-link device and the access point multi-link device, namely link 1 and link 2. In the initial state, TID1 and TID2 are mapped on link 1, and TID2 and TID3 are mapped on link 2. If at this time, the site multi-link device has a large number of service flows of TID3, in order to meet the service flow requirements of TID3, TID2 on link 2 needs to be removed. At this time, the site multi-link device updates the mapping information of each TID to the link, that is, executes the remapping forced mode, such as Fig.10 As shown, after updating the mapping information of each TID to the link, the TID on link 1 remains unchanged, and only TID3 is mapped on link 2.

[0096] Optionally, the station multi-link device may send the first indication message to the subordinate AP in the access point multi-link device through the subordinate station therein.

[0097] It should be noted that, for an established link, if there is at least one TID mapped to the link, the state of the link is an enabled state, otherwise, the state of the link is a disabled state.

[0098] Optionally, the uplink corresponding to the subsidiary site is in an enabled state.

[0099] Optionally, the uplink corresponding to the subordinate AP is in an enabled state.

[0100] It should be understood that the above-mentioned first indication message can be an implicit indication message or an explicit indication message, and the present application does not impose any limitation on this.

[0101] It should be understood that the first indication message is used to indicate that the access point multi-link device does not need to respond to the site multi-link device for the first indication message. That is, the first indication message is used to indicate the use of the remapping forced mode. In addition, the first indication message includes: updated first mapping information.

[0102] Optionally, the updated first mapping information includes: mapping information from at least one traffic identifier to a corresponding uplink set.

[0103] It should be noted that, when the traffic identifier involved in the first mapping information is all uplink traffic identifiers of the site multi-link device, the at least one traffic identifier may be all uplink traffic identifiers of the site multi-link device. When the traffic identifier involved in the first mapping information is an uplink traffic identifier of the corresponding mapping information to be updated, the at least one traffic identifier may be all uplink traffic identifiers of the corresponding mapping information to be updated.

[0104] Optionally, for any one of the at least one traffic identifier, after the first mapping information is updated, the uplink set corresponding to the traffic identifier is a non-empty subset of the uplink set established between the site multi-link device and the access point multi-link device. Fig.10 As shown, after updating the mapping information of each TID, the uplink set corresponding to TID1 still includes: link 1, the uplink set corresponding to TID2 only includes: link 1, and the uplink set corresponding to TID3 still includes: link 2. The uplink set established between the site multi-link device and the access point multi-link device includes: link 1 and link 2. Therefore, it can be seen that the uplink sets corresponding to TID1, TID2 and TID3 are all non-empty subsets of the uplink set established between the site multi-link device and the access point multi-link device.

[0105] Optionally, for any one of the at least one traffic identifier, after the first mapping information is updated, the uplink set corresponding to the traffic identifier is a non-empty subset of the first mapping link set between the site multi-link device and the access point multi-link device; wherein the first mapping link set is the uplink set corresponding to the traffic identifier before the first mapping information is updated. Fig.10 As shown, before updating the mapping information of each TID, the uplink set corresponding to TID1 (i.e., the first mapping link set corresponding to TID1) includes: link 1, and after updating the mapping information, the uplink set corresponding to TID1 still includes: link 1. Before updating the mapping information of each TID, the uplink set corresponding to TID2 (i.e., the first mapping link set corresponding to TID2) includes: link 1 and link 2, and after updating the mapping information, the uplink set corresponding to TID2 only includes: link 1. Before updating the mapping information of each TID, the uplink set corresponding to TID3 (i.e., the first mapping link set corresponding to TID3) includes: link 2, and after updating the mapping information, the uplink set corresponding to TID3 still includes: link 2. It can be seen that after the mapping information is updated, the uplink sets corresponding to TID1, TID2 and TID3 are all non-empty subsets of their respective corresponding first mapping link sets.

[0106] Further, after receiving the updated first mapping information, the access point multi-link device will update the second mapping information, wherein the second mapping information is the mapping information from the traffic identifier to the uplink at the access point multi-link device side.

[0107] It should be understood that the traffic identifier involved in the second mapping information may be all uplink traffic identifiers of the site multi-link device, or may be an uplink traffic identifier of the corresponding mapping information to be updated, and the present application does not impose any limitation on this.

[0108] It should be understood that the traffic identifier involved in the second mapping information may be one or more. If it is one, then the second mapping information is the mapping information of the traffic identifier to the uplink on the access point multi-link device side. If it is more than one, then the second mapping information is the mapping information of these multiple traffic identifiers to the uplink on the access point multi-link device side.

[0109] It should be understood that before the first mapping information and the second mapping information are updated, ie, in the initial stage, the first mapping information and the second mapping information are the same.

[0110] It should be understood that the updated first mapping information is the same as the updated second mapping information, that is, the mapping information from the traffic identifier to the link remains consistent on the site multi-link device side and the access point multi-link device side.

[0111] In summary, in the present application, a remapping forced mode may be adopted, that is, the access point multi-link device does not need to respond to the site multi-link device for the first indication message, thereby reducing signaling overhead.

[0112] As described above, the first indication message may be an implicit indication message or an explicit indication message, that is, an implicit manner may be used to indicate that the access point multi-link device does not need to respond to the site multi-link device for the first indication message, or an explicit manner may be used to indicate that the access point multi-link device does not need to respond to the site multi-link device for the first indication message. These two manners are described below respectively:

[0113] Example 2

[0114] The first indication message may be an explicit indication message, for example: the first indication message includes: first indication information. The first indication information is used to indicate that the access point multi-link device does not need to respond to the site multi-link device for the first indication message. The following will illustrate the carrying method of the first indication message by way of example:

[0115] Example 1: Fig.11 A schematic diagram of a mapping negotiation request frame provided in an embodiment of the present application, such as Fig.11As shown, the mapping negotiation request frame includes a mapping negotiation information element, and the mapping negotiation information element includes: first indication information and updated first mapping information. Optionally, the first indication information may carry a mandatory field in a control field in the mapping negotiation information element. In addition, the mapping negotiation request frame may also include: a category field, a mapping negotiation request field, and other fields, etc. This application does not limit other fields in the mapping negotiation request frame except the mapping negotiation information element.

[0116] It should be understood that the mapping negotiation request frame is a form of an action frame.

[0117] Optionally, the category field may be populated with an Extremely High Throughput (EHT) category.

[0118] Optionally, the length of the first indication information may be 1 bit, wherein the first indication information may be 1, indicating that the access point multi-link device does not need to respond to the site multi-link device for the first indication message. If the field where the first indication information is located is not filled with 1, for example, 0, it indicates that the access point multi-link device needs to respond to the site multi-link device for the first indication message.

[0119] It should be noted that Fig.11 The provided mapping negotiation request frame is an improvement on the mapping negotiation request frame in the prior art. The mapping negotiation request frame in the prior art has no mandatory field. In the present application, the mapping negotiation request frame carries a mandatory field, which can be used to fill in the first indication information.

[0120] Example 2: Fig.12 A schematic diagram of a forced mapping frame provided in an embodiment of the present application, such as Fig.12 As shown, the forced mapping frame includes a forced mapping field and a mapping negotiation information element, the forced mapping field can be filled with the first indication information, and the mapping negotiation information element includes: the updated first mapping information. In addition, the forced mapping frame can also include: a category field and other fields, etc. This application does not limit other fields in the forced mapping frame except the mapping negotiation information element.

[0121] It should be understood that the mandatory mapping frame is a form of action frame.

[0122] Optionally, the category field may be populated with the EHT category.

[0123] It should be noted that Fig.12 The mandatory mapping frame provided is the same as Fig.11 The mapping negotiation request frame provided differs in that Fig.12 The mandatory mapping frame provided does not carry mandatory fields in the mapping negotiation information element.

[0124] It should be understood that the carrying method of the first indication information is not limited to Fig.11 and Fig.12 The situation shown can also be carried in other frames, or carried in other fields in a mapping negotiation request frame or a forced mapping frame, and this application does not impose any restrictions on this.

[0125] Further, after the access point multi-link device receives the mapping negotiation request frame, it parses the mandatory field in the mapping negotiation request frame. If the mandatory field carries the first indication information, such as 1, it indicates that there is no need to respond to the site multi-link device for the mapping negotiation request frame. If the mandatory field does not carry the first indication information, such as 0, it indicates that it is necessary to respond to the site multi-link device for the mapping negotiation request frame. Alternatively, after the access point multi-link device receives the mandatory mapping frame, if the mandatory mapping field after the type field is parsed, it indicates that there is no need to respond to the site multi-link device for the mandatory mapping frame.

[0126] In the present application, the first indication message may explicitly indicate that the access point multi-link device does not need to respond to the site multi-link device with respect to the first indication message, thereby reducing signaling overhead.

[0127] Example 3

[0128] The first indication message may be an implicit indication message. This implicit indication method is described below by way of example:

[0129] Optionally, after receiving the first indication message, the access point multi-link device parses and obtains the updated first mapping information, based on which, updates the second mapping information. Further, the access point multi-link device may enter into the following comparison: whether the uplink set corresponding to each traffic identifier is a non-empty subset of the first mapping link set between the site multi-link device and the access point multi-link device. If yes, it is determined that there is no need to respond to the site multi-link device for the first indication message.

[0130] For example, Fig.10As shown, before updating the mapping information of each TID, the uplink set corresponding to TID1 (i.e., the first mapping link set corresponding to TID1) includes: link 1, and after updating the mapping information, the uplink set corresponding to TID1 still includes: link 1. Before updating the mapping information of each TID, the uplink set corresponding to TID2 (i.e., the first mapping link set corresponding to TID2) includes: link 1 and link 2, and after updating the mapping information, the uplink set corresponding to TID2 only includes: link 1. Before updating the mapping information of each TID, the uplink set corresponding to TID3 (i.e., the first mapping link set corresponding to TID3) includes: link 2, and after updating the mapping information, the uplink set corresponding to TID3 still includes: link 2. It can be seen that after the mapping information is updated, the uplink sets corresponding to TID1, TID2 and TID3 are all non-empty subsets of their respective first mapping link sets. Based on this, the access point multi-link device determines that there is no need to respond to the site multi-link device for the first indication message.

[0131] The following is an example of how to carry the first indication message:

[0132] Fig.13 A schematic diagram of a mapping negotiation request frame provided in an embodiment of the present application, such as Fig.13 As shown, the mapping negotiation request frame includes: a mapping negotiation information element, and the mapping negotiation information element includes the updated first mapping information, but does not include the first indication information. In addition, the mapping negotiation request frame may also include: a category field, a mapping negotiation request field and other fields, etc. The present application does not impose any restrictions on other fields in the mapping negotiation request frame except the mapping negotiation information element.

[0133] It should be understood that the mapping negotiation request frame is a form of an action frame.

[0134] Optionally, the category field may be populated with the EHT category.

[0135] In the present application, the first indication message may implicitly indicate that the access point multi-link device does not need to respond to the site multi-link device for the first indication message, thereby reducing signaling overhead.

[0136] Example 4

[0137] Fig.14 An interactive flow chart of another wireless communication method provided in an embodiment of the present application, such as Fig.14 As shown, the method includes:

[0138] S1410: The access point multi-link device updates the third mapping information.

[0139] S1420: The access point multi-link device generates a second indication message.

[0140] S1430: The access point multi-link device sends a second indication message to the site multi-link device.

[0141] S1440: The site multi-link device updates the fourth mapping information according to the updated third mapping information.

[0142] It should be understood that the third mapping information is mapping information from the traffic identifier to the downlink at the access point multi-link device side.

[0143] It should be understood that the traffic identifier involved in the third mapping information may be all downlink traffic identifiers of the access point multi-link device, or may be a downlink traffic identifier of the corresponding mapping information to be updated, and the present application does not impose any limitation on this.

[0144] It should be understood that the traffic identifier involved in the third mapping information may be one or more. If it is one, then the third mapping information is the mapping information of the traffic identifier to the downlink on the access point multi-link device side. If it is more than one, then the third mapping information is the mapping information of these multiple traffic identifiers to the downlink on the access point multi-link device side.

[0145] It should be understood that a traffic identifier may correspond to or be mapped to at least one link. For example, TID1 may be mapped to link 1 and link 2 , and TID2 may be mapped to link 1 .

[0146] It should be understood that the access point multi-link device can update the first mapping information in the above compression scenario.

[0147] For example, Fig.15 A schematic diagram of updating the mapping information of the traffic identifier to the link provided in the embodiment of the present application, such as Fig.15 As shown, two links, Link 1 and Link 2, are established between AP MLD and two site multi-link devices STA MLD 1 and STA MLD 2. In the initial state, for the above STA MLD 1 and STA MLD 2, TID1 and TID7 are mapped on Link 1 and Link 2. AP MLD is for system optimization needs. For example, STA MLD2 has a large number of service flows of TID7 at this time. To ensure the service flow requirements of TID7 of STA MLD2, the access point multi-link device selects Link 2 to only transmit the service flow of TID7 according to the link status of STA MLD2. For STA MLD1, TID1 and TID7 are mapped to Link 1, and TID mapping is not performed on Link 2. At this time, the AP MLD executes the remapping forced mode and updates the mapping information of each TID to the link.

[0148] Optionally, the subordinate AP of the access point multi-link device may send a second indication message to the subordinate stations in the station multi-link device.

[0149] Optionally, the downlink corresponding to the subsidiary site is in an enabled state.

[0150] Optionally, the downlink corresponding to the subordinate AP is in an enabled state.

[0151] Optionally, the access point multi-link device may send the second indication message to the multiple site multi-link devices by adopting an orthogonal frequency division multiple access (OFDMA) method, but is not limited thereto.

[0152] It should be understood that the above-mentioned second indication message can be an implicit indication message or an explicit indication message, and the present application does not impose any limitation on this.

[0153] It should be understood that the second indication message is used to indicate that the site multi-link device does not need to respond to the access point multi-link device for the second indication message, that is, the second indication message is used to indicate the use of the remapping forced mode. In addition, the second indication message includes: updated third mapping information.

[0154] Optionally, the updated third mapping information includes: mapping information from at least one traffic identifier to a corresponding downlink set.

[0155] It should be noted that, when the traffic identifier involved in the third mapping information is all downlink traffic identifiers of the access point multi-link device, the at least one traffic identifier may be all downlink traffic identifiers of the access point multi-link device. When the traffic identifier involved in the third mapping information is a downlink traffic identifier of the corresponding mapping information to be updated, the at least one traffic identifier may be all downlink traffic identifiers of the corresponding mapping information to be updated.

[0156] Optionally, for any traffic identifier of the at least one traffic identifier, after updating the third mapping information, the downlink set corresponding to the traffic identifier is a non-empty subset of the downlink set established between the site multi-link device and the access point multi-link device.

[0157] Optionally, for any one of the at least one traffic identifiers, after updating the third mapping information, the downlink set corresponding to the traffic identifier is a non-empty subset of the second mapping link set between the site multi-link device and the access point multi-link device; wherein the second mapping link set is the downlink set corresponding to the traffic identifier before updating the third mapping information.

[0158] Further, after receiving the updated third mapping information, the site multi-link device will update fourth mapping information, wherein the fourth mapping information is mapping information from the traffic identifier to the downlink at the site multi-link device side.

[0159] It should be understood that the traffic identifier involved in the fourth mapping information may be all downlink traffic identifiers of the access point multi-link device, or may be a downlink traffic identifier of the corresponding mapping information to be updated, and the present application does not impose any limitation on this.

[0160] It should be understood that the traffic identifier involved in the fourth mapping information may be one or more. If it is one, then the fourth mapping information is the mapping information of the traffic identifier to the downlink on the site multi-link device side. If it is more than one, then the fourth mapping information is the mapping information of the multiple traffic identifiers to the downlink on the site multi-link device side.

[0161] It should be understood that before the third mapping information and the fourth mapping information are updated, ie, in an initial stage, the fourth mapping information and the fourth mapping information are the same.

[0162] It should be understood that the updated third mapping information is the same as the updated fourth mapping information, that is, the mapping information from the traffic identifier to the link remains consistent on the site multi-link device side and the access point multi-link device side.

[0163] In summary, in the present application, a remapping forced mode may be adopted, that is, the site multi-link device does not need to respond to the access point multi-link device for the second indication message, thereby reducing signaling overhead.

[0164] As described above, the second indication message may be an implicit indication message or an explicit indication message, that is, an implicit manner may be used to indicate that the site multi-link device does not need to respond to the access point multi-link device for the second indication message, or an explicit manner may be used to indicate that the site multi-link device does not need to respond to the access point multi-link device for the second indication message. These two manners are described below respectively:

[0165] Example 5

[0166] The second indication message may be an explicit indication message, for example: the second indication message includes: second indication information. The second indication information is used to indicate that the site multi-link device does not need to respond to the access point multi-link device for the second indication message. The following will illustrate the carrying method of the second indication message by way of example:

[0167] Example 1: Fig.16 A schematic diagram of a mapping negotiation request frame provided in an embodiment of the present application, such as Fig.16As shown, the mapping negotiation request frame includes a mapping negotiation information element, and the mapping negotiation information element includes: second indication information and updated third mapping information. Optionally, the second indication information may carry a mandatory field in a control field in the mapping negotiation information element. In addition, the mapping negotiation request frame may also include: a category field, a mapping negotiation request field, and other fields, etc. The present application does not limit other fields in the mapping negotiation request frame except the mapping negotiation information element.

[0168] It should be understood that the mapping negotiation request frame is a form of an action frame.

[0169] Optionally, the category field may be populated with the EHT category.

[0170] Optionally, the length of the second indication information may be 1 bit, wherein the second indication information may be 1, indicating that the site multi-link device does not need to respond to the access point multi-link device for the second indication message. If the field where the second indication information is located is not filled with 1, for example, 0, it indicates that the site multi-link device needs to respond to the access point multi-link device for the second indication message.

[0171] It should be noted that Fig.16 The provided mapping negotiation request frame is an improvement on the mapping negotiation request frame in the prior art. The mapping negotiation request frame in the prior art has no mandatory field. In the present application, the mapping negotiation request frame carries a mandatory field, which can be used to fill in the second indication information.

[0172] Example 2: Fig.17 A schematic diagram of a forced mapping frame provided in an embodiment of the present application, such as Fig.17 As shown, the forced mapping frame includes a forced mapping field and a mapping negotiation information element, the forced mapping field can be filled with the second indication information, and the mapping negotiation information element includes: the updated third mapping information. In addition, the forced mapping frame can also include: a category field and other fields, etc. This application does not limit other fields in the forced mapping frame except the mapping negotiation information element.

[0173] It should be understood that the mandatory mapping frame is a form of action frame.

[0174] Optionally, the category field may be populated with the EHT category.

[0175] It should be noted that Fig.17 The mandatory mapping frame provided is the same as Fig.16 The mapping negotiation request frame provided differs in that Fig.17 The mandatory mapping frame provided does not carry mandatory fields in the mapping negotiation information element.

[0176] It should be understood that the carrying method of the second indication information is not limited to Fig.16 and Fig.17 The situation shown can also be carried in other frames, or carried in other fields in a mapping negotiation request frame or a forced mapping frame, and this application does not impose any restrictions on this.

[0177] Further, after the site multi-link device receives the mapping negotiation request frame, it parses the mandatory field in the mapping negotiation request frame. If the mandatory field carries the second indication information, such as 1, it indicates that there is no need to respond to the access point multi-link device for the mapping negotiation request frame. If the mandatory field does not carry the second indication information, such as 0, it indicates that it is necessary to respond to the access point multi-link device for the mapping negotiation request frame. Alternatively, after the site multi-link device receives the mandatory mapping frame, if the mandatory mapping field after the type field is parsed, it indicates that there is no need to respond to the site multi-link device for the mandatory mapping frame.

[0178] In the present application, the second indication message may explicitly indicate that the site multi-link device does not need to respond to the access point multi-link device for the second indication message, thereby reducing signaling overhead.

[0179] Example 6

[0180] The second indication message may be an implicit indication message. This implicit indication method is described below by way of example:

[0181] Optionally, after receiving the second indication message, the site multi-link device parses and obtains the updated third mapping information, based on which, updates the fourth mapping information. Further, the site multi-link device may enter into the following comparison: whether the downlink set corresponding to each traffic identifier is a non-empty subset of the second mapping link set between the site multi-link device and the access point multi-link device. If yes, it is determined that there is no need to respond to the access point multi-link device for the second indication message.

[0182] The following is an example of how to carry the second indication message:

[0183] Fig.18 A schematic diagram of a mapping negotiation request frame provided in an embodiment of the present application, such as Fig.18 As shown, the mapping negotiation request frame includes: a mapping negotiation information element, and the mapping negotiation information element includes the updated third mapping information, but does not include the second indication information. In addition, the mapping negotiation request frame may also include: a category field, a mapping negotiation request field and other fields, etc. The present application does not impose any restrictions on other fields in the mapping negotiation request frame except the mapping negotiation information element.

[0184] It should be understood that the mapping negotiation request frame is a form of an action frame.

[0185] Optionally, the category field may be populated with the EHT category.

[0186] In the present application, the second indication message may implicitly indicate that the site multi-link device does not need to respond to the access point multi-link device for the second indication message, thereby reducing signaling overhead.
