Description

[Technical field]

[0001] The present embodiment relates to the field of communications, and more particularly to a wireless communication method, a terminal device, and a network device. [Background technology]

[0002] 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 traffic identifier (TID)-to-link mapping. The standard requires that each TID be mapped to a link or a set of links, so that the service flow corresponding to the TID can be carried.

[0003] Currently, the change of the mapping information from traffic identifiers to links is obtained through negotiation with a Multi-link Device (MLD), and includes three cases as follows: 1. If the link set responded by the receiving terminal is the same as the link set provided by the sending terminal, the mapping result from traffic identifiers to links is the link set provided by the sending terminal, and the negotiation is deemed successful; 2. If the receiving side provides a set of spare link sets, and the spare link set is a non-empty subset of the link set provided by the sending terminal, the mapping result is the spare link set provided by the receiving side, and the negotiation is deemed successful; 3. If the link set responded by the receiving side is an empty set, the original mapping from traffic identifiers to links is reserved, and the negotiation is deemed unsuccessful.

[0004] In summary, currently, all changes to mapping information from traffic identifiers to links adopt the request / response negotiation mode. However, the traffic identifier-to-link mapping scenarios are diverse, and in some specific scenarios, it may not be necessary to adopt the negotiation mode, in which case adopting such a negotiation mode will cause the problem of too large signaling overhead.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, the technical solutions in the embodiments of the present invention will be described with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part, not all, of the embodiments of the present invention. For the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts shall be included in the protection scope of the present invention.

[0024] As described above, currently, the change of mapping information from traffic identifier to link is obtained through MLD negotiation, which includes the above three cases, and in fact, these three cases are applied to the expansion, compression and switching scenarios of traffic identifier to link mapping negotiation, and the following describes the application of the above three cases in the three scenarios.

[0025] FIG. 1 is a schematic diagram of an extended scenario of traffic identifier-to-link mapping negotiation. As shown in FIG. 1, the original mapping includes a mapping from TID4 to a 5 GHz link, the mapping provided by MLD1 includes a mapping from TID4 to a 2.4 and 5 GHz link, and MLD2 agrees with the mapping provided by MLD1, i.e., the mapping responded by MLD2 includes a mapping from TID4 to a 2.4 and 5 GHz link. Based on this, the mapping negotiation is successful, and the negotiated mapping includes a mapping from TID4 to a 2.4 and 5 GHz link.

[0026] FIG. 2 is a schematic diagram of another extended scenario of traffic identifier-to-link mapping negotiation. As shown in FIG. 2, the original mapping includes a mapping of TID4 to a 5 GHz link, the mapping provided by MLD1 includes mapping of TID4 to 2.4 and 5 GHz links, and MLD2 does not agree to map TID4 to the 2.4 GHz link, i.e., the mapping responded by MLD2 includes a mapping of TID4 to a 5 GHz link. In this case, the negotiation on the mapping is deemed successful, and the negotiated mapping includes a mapping of TID4 to a 5 GHz link.

[0027] FIG. 3 is a schematic diagram of a compressed scenario of traffic identifier-to-link mapping negotiation. As shown in FIG. 3, the original mapping includes mapping from TID4 to 2.4 and 5 GHz links, the mapping provided by MLD1 includes mapping from TID4 to the 5 GHz link, and MLD2 agrees with the mapping provided by MLD1, i.e., the mapping responded by MLD2 includes mapping from TID4 to the 5 GHz link. Based on this, the mapping negotiation is successful, and the negotiated mapping includes mapping from TID4 to the 5 GHz link.

[0028] FIG. 4 is a schematic diagram of a switching scenario of traffic identifier-to-link mapping negotiation. As shown in FIG. 4, the original mapping includes a mapping of TID4 to a 5 GHz link, the mapping provided by MLD1 includes a mapping of TID4 to a 6 GHz link, and MLD2 agrees with the mapping provided by MLD1, i.e., the mapping responded by MLD2 includes a mapping of TID4 to a 6 GHz link. Based on this, the mapping negotiation is successful, and the negotiated mapping includes a mapping of TID4 to a 6 GHz link.

[0029] FIG. 5 is a schematic diagram of another switching scenario of traffic identifier-to-link mapping negotiation. As shown in FIG. 5, the original mapping includes a mapping of TID4 to a 5 GHz link, the mapping provided by MLD1 includes a mapping of TID4 to a 6 GHz link, and MLD2 does not agree with the mapping provided by MLD1, i.e., the link set responded by MLD2 is an empty set. Based on this, the mapping negotiation fails, and thus the original mapping is not changed, i.e., includes a mapping of TID4 to a 5 GHz link.

[0030] FIG. 6 is a schematic diagram of yet another switching scenario of traffic identifier-to-link mapping negotiation, as shown in FIG. 6, the original mapping includes a mapping of TID4 to a 5 GHz link, the mapping provided by MLD1 includes mapping of TID4 to 2.4 and 6 GHz links, MLD2 does not agree to map TID4 to the 2.4 GHz link, and the mapping responded by MLD2 includes a mapping of TID4 to a 6 GHz link, based on which the mapping negotiation is considered successful, and the negotiated mapping includes a mapping of TID4 to a 6 GHz link.

[0031] As described above, currently, all mappings from traffic identifiers to links adopt a request / response negotiation mode, but in some specific scenarios, the transmitting terminal can determine the mapping scheme and the receiving terminal only needs to obtain the mapping scheme. For details, please refer to the examples below.

[0032] For example, in station multilink device (non-AP MLD), when there is a large number of service flows corresponding to a certain uplink TID, it is necessary to try to provide a dedicated link set for the uplink TID. In this case, the station multilink device issues a remapping request to remove other uplink TIDs on at least one original link of the TID mapping, and in this case, in the updated traffic identifier-to-link mapping, the link set corresponding to each TID is a non-empty subset of each TID original mapping link set, corresponding to a compression scenario. In this case, the station multilink device expects the access point multilink device to directly accept the remapping request.

[0033] For example, from the viewpoint of improving system performance, the access point multilink device (AP MLD) has the link status information of all stations associated with it, and therefore can obtain a better mapping result from traffic identifiers to links through a certain algorithm, and ensure that the mapping result can also meet the transmission requirements of the station multilink device. In this case, the access point multilink device expects the station multilink device to directly accept this better mapping result.

[0034] In the above scenario, or any other possible scenario, if the receiving terminal still sends back response information, the signaling overhead will increase.

[0035] To solve the above technical problems, the present application adopts a forced mode, i.e., instructs the receiving terminal that it does not need to return response information, thereby reducing signaling overhead.

[0036] In the following, the architecture of the communication system in this application will be described with reference to FIG.

[0037] Exemplarily, Fig. 7 is a schematic diagram of the architecture of a communication system according to an embodiment of the present application. Referring to Fig. 7, the communication system includes a station multilink device 710 and an access point multilink device 720, and at least two links can exist between the station multilink device 710 and the access point multilink device 720 for wireless communication. Exemplarily, the communication system may include a plurality of station multilink devices 710 or a plurality of access point multilink devices 720, and the embodiment of the present application is not limited thereto.

[0038] It should be understood that the station multilink equipment 710 may include at least one station (STA), and thus the station multilink equipment 710 may be understood as a logical entity, where FIG. 7 exemplarily illustrates that the station multilink equipment 710 includes two STAs.

[0039] It should be understood that the access point multi-link device 720 may include at least one access point (AP), and thus the access point multi-link device 720 may be understood as a logical entity, where FIG. 7 exemplarily illustrates that the access point multi-link device 720 includes two APs.

[0040] It should be understood that there can be one link between the AP and one STA.

[0041] For example, the communication system shown in FIG. 7 may further include other network entities such as a Mobility Management Entity (MME) and an Access and Mobility Management Function (AMF), and the present embodiment is not limited thereto.

[0042] It should be understood that the terms "system" and "network" are always used interchangeably herein.

[0043] For example, the communication system in the present embodiment may be applied to a carrier aggregation (CA) scenario, a dual connectivity (DC) scenario, a standalone (SA) network deployment scenario, etc.

[0044] Illustratively, embodiments of the present application may be applied to unlicensed spectrum or licensed spectrum, where unlicensed spectrum may be considered as shared spectrum and licensed spectrum may be considered as non-shared spectrum.

[0045] It should be understood that the station multilink device and the access point multilink device first need to perform multilink discovery, multilink establishment, and traffic identifier to link mapping establishment, and the contents of these three parts will be described below.

[0046] Step 1: Multilink Discovery The basic purpose of MultiLink Discovery is to enable a Station MultiLink device to obtain information about an Access Point MultiLink device and all the links it supports by receiving a Beacon frame or a Probe Response frame from any of the Access Point MultiLink device's associated APs, which is essentially a MultiLink Scan process, i.e., MultiLink Discovery.

[0047] After the MultiLink discovery phase is completed, the station MultiLink device obtains full or partial information of the access point MultiLink device's attached AP.

[0048] Step 2: Multi-link establishment The basic purpose of multi-link establishment is to enable the station multi-link equipment to exchange complete information of each attached STA and AP with the access point multi-link equipment, and complete the multi-link establishment according to each capability information, the essence of which is the multi-link association process, i.e., multi-link establishment.

[0049] The following steps 2.1 and 3 show the establishment process of traffic identifier-to-link mapping information between station multilink equipment and access point multilink equipment in case of non-default mode of traffic identifier-to-link mapping.

[0050] Here, the default mode of traffic identifier-to-link mapping is to map all traffic identifiers to all already established links. If a non-default mode is adopted at initialization, a preliminary negotiation of traffic identifier-to-link mapping needs to be performed between the station multilink device and the access point multilink device.

[0051] Step 2.1 (Selective Scheme 1 for Establishing Mapping from Traffic Identifiers to Links): Establishing mapping information from traffic identifiers to links in the multi-link establishment phase.

[0052] Exemplarily, the establishment of mapping information from traffic identifiers to links can be included in the multi-link establishment phase. A specific embodiment is to place the mapping information from traffic identifiers to links as a field in the ML information element of the associated request / response frame used in the multi-link establishment phase. Figure 8 is a schematic diagram of an ML information element according to an embodiment of the present application, and as shown in Figure 8, the ML information element includes the mapping information from traffic identifiers to links.

[0053] Step 3 (Selective Method 2 for Establishing Mapping from Traffic Identifiers to Links): The stage of establishing the multi-links and the stage of establishing mapping information from traffic identifiers to links are independent.

[0054] Illustratively, the traffic identifier-to-link mapping information may be included in an independent stage, in which an information element of the corresponding management frame is used to include the traffic identifier-to-link mapping information.

[0055] Through the above steps, the establishment of mapping information from traffic identifiers to links between the station multilink equipment and the access point multilink equipment is completed.

[0056] This application focuses on updating mapping information from traffic identifiers to links, and the technical solutions of this application are described in detail below.

[0057] Example 1 FIG. 9 is an interaction flowchart of a wireless communication method according to an embodiment of the present application. As shown in FIG. 9, the method includes the following steps:

[0058] In step S910, the station multilink device updates the first mapping information.

[0059] In step S920, the station multilink device generates a first indication message.

[0060] In step S930, the station multilink device sends a first indication message to the access point multilink device.

[0061] In step S940, the access point multilink device updates the second mapping information according to the updated first mapping information.

[0062] It should be understood that the first mapping information is mapping information from a traffic identifier to an uplink on the station multilink equipment side.

[0063] It should be understood that the traffic identifiers in the first mapping information may be all uplink traffic identifiers of the station multilink equipment, or may be the uplink traffic identifiers of the corresponding mapping information to be updated, and the present application is not limited thereto.

[0064] It should be understood that the traffic identifier in the first mapping information may be one or more, and if it is one, the first mapping information is mapping information from the traffic identifier to an uplink at the station multilink device side, and if it is more than one, the first mapping information is mapping information from these multiple traffic identifiers to uplinks at the station multilink device side.

[0065] It should be understood that one traffic identifier may correspond or map to at least one link, for example, TID1 may map to link1 and link2, and TID2 may map to link1.

[0066] It should be understood that the station multilink equipment can update the first mapping information in the above compression scenario.

[0067] Illustratively, FIG. 10 is a schematic diagram of updating mapping information from traffic identifiers to links according to an embodiment of the present application. As shown in FIG. 10, there are two links between a station multilink device and an access point multilink device, which are link 1 and link 2 respectively. In the initial state, TID1 and TID2 are mapped to link 1, and TID2 and TID3 are mapped to link 2. At this time, if the station multilink device has a large number of service flows of TID3, it is necessary to remove TID2 in link 2 to meet the service flow requirements of TID3. In this case, the station multilink device updates the mapping information from each TID to a link, that is, performs a forced re-mapping mode. As shown in FIG. 10, after updating the mapping information from each TID to a link, the TID in link 1 is not changed, and only TID3 is mapped to link 2.

[0068] Exemplarily, the station multilink device may send a first indication message to the attached AP of the access point multilink device via its attached station.

[0069] It should be noted that for an established link, if at least one TID is mapped to the link, the state of the link is valid; otherwise, the state of the link is invalid.

[0070] Illustratively, the uplink corresponding to the attached station is in an active state.

[0071] Illustratively, the uplink corresponding to the attached AP is in an enabled state.

[0072] It should be understood that the above first instruction message may be an implicit instruction message or an explicit instruction message, and the present application is not limited thereto.

[0073] It should be understood that the first indication message is used to instruct the access point multilink device that it does not need to respond to the first indication message to the station multilink device, that is, the first indication message is used to instruct the access point multilink device to adopt a remapping forced mode, and the first indication message further includes the updated first mapping information.

[0074] Exemplarily, the updated first mapping information includes mapping information from at least one traffic identifier to a corresponding uplink set.

[0075] It is noted that, when the traffic identifier in the first mapping information is all the uplink traffic identifiers of the station multilink equipment, the at least one traffic identifier may be all the uplink traffic identifiers of the station multilink equipment; when the traffic identifier in the first mapping information is the uplink traffic identifier of the corresponding mapping information to be updated, the at least one traffic identifier may be all the uplink traffic identifiers of the corresponding mapping information to be updated.

[0076] Exemplarily, for any one of the at least one traffic identifiers, after updating the first mapping information, the uplink set corresponding to the traffic identifier is a non-empty subset of the uplink set established between the station multilink device and the access point multilink device. For example, as shown in FIG. 10, 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. Meanwhile, the uplink set established between the station multilink device and the access point multilink device includes link 1 and link 2, and it can be seen that the uplink sets corresponding to TID1, TID2 and TID3 respectively are non-empty subsets of the uplink set established between the station multilink device and the access point multilink device.

[0077] Exemplarily, for any one of the at least one traffic identifiers, after updating the first mapping information, the uplink set corresponding to the traffic identifier is a non-empty subset of the first mapping link set between the station multilink device and the access point multilink device. Here, the first mapping link set is the uplink set corresponding to the traffic identifier before the first mapping information is updated. For example, as shown in FIG. 10, 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. As can be seen, after updating the mapping information, the uplink sets corresponding to TID1, TID2, and TID3 are non-empty subsets of the corresponding first mapping link sets, respectively.

[0078] Furthermore, after receiving the updated first mapping information, the access point multilink device updates the second mapping information, where the second mapping information is mapping information from the traffic identifier to the uplink at the access point multilink device side.

[0079] It should be understood that the traffic identifiers in the second mapping information may be all uplink traffic identifiers of the station multilink equipment, or may be the uplink traffic identifiers of the corresponding mapping information to be updated, and the present application is not limited thereto.

[0080] It should be understood that the traffic identifier in the second mapping information may be one or more, and if it is one, the second mapping information is mapping information from the traffic identifier to an uplink at the access point multilink device side, and if it is more than one, the second mapping information is mapping information from these more than one traffic identifier to an uplink at the access point multilink device side.

[0081] It should be understood that before updating the first mapping information and the second mapping information, that is, at the initial stage, the first mapping information is the same as the second mapping information.

[0082] 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 traffic identifiers to links on the station multilink device side and the access point multilink device side are consistent.

[0083] In summary, in this application, a forced remapping mode can be adopted, that is, the access point multilink device does not need to respond to the station multilink device for the first indication message, thereby reducing signaling overhead.

[0084] As mentioned above, the first indication message can be an implicit indication message or an explicit indication message, that is, the first indication message can be an implicit manner to indicate to the access point multilink device that the station multilink device does not need to respond to the first indication message, or the first indication message can be an explicit manner to indicate to the access point multilink device that the station multilink device does not need to respond to the first indication message. The following describes these two methods respectively.

[0085] Example 2 The first indication message may be an explicit indication message, for example, the first indication message includes first indication information, where the first indication information is used to indicate to the access point multilink device that the station multilink device does not need to respond to the first indication message. The following takes an example to describe the manner of carrying the first indication message.

[0086] In Example 1, Figure 11 is a schematic diagram of a mapping negotiation request frame according to an embodiment of the present application, as shown in Figure 11, 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. Exemplarily, the first indication information can be carried by a mandatory field in a control field of the mapping negotiation information element. In addition, the mapping negotiation request frame can further include a category field, a mapping negotiation request field, and other fields, and the present application is not limited to other fields other than the mapping negotiation information element in the mapping negotiation request frame.

[0087] It should be understood that a mapping negotiation request frame is a type of action frame.

[0088] Illustratively, the category field may be filled with an Extremely High Throughput (EHT) category.

[0089] Exemplarily, the length of the first indication information may be 1 bit, where the first indication information may be 1, which indicates that the access point multilink device does not need to respond to the first indication message to the station multilink device. If the field in which the first indication information is located is not 1, for example, 0, it indicates that the access point multilink device needs to respond to the first indication message to the station multilink device.

[0090] It should be noted that the mapping negotiation request frame provided in FIG. 11 is an improvement to the mapping negotiation request frame in the prior art, in which the mapping negotiation request frame in the prior art does not have a forced field, and in the present application, the mapping negotiation request frame carries a forced field, which can be used to fill the first indication information.

[0091] In Example 2, Figure 12 is a schematic diagram of a forced mapping frame according to an embodiment of the present application, as shown in Figure 12, the forced mapping frame includes a forced mapping field and a mapping negotiation information element, the forced mapping field can be filled with first indication information, and the mapping negotiation information element includes the updated first mapping information. In addition, the forced mapping frame can further include a category field and other fields, etc., and the present application is not limited to other fields in the forced mapping frame other than the mapping negotiation information element.

[0092] It should be understood that a mandatory mapping frame is a type of action frame.

[0093] Illustratively, the category field may be filled with an EHT category.

[0094] It should be noted that the difference between the forced mapping frame provided in FIG. 12 and the mapping negotiation request frame provided in FIG. 11 is that the forced mapping frame provided in FIG. 12 does not carry a forced field in the mapping negotiation information element.

[0095] It should be understood that the manner of carrying the first instruction information is not limited to the situation shown in Figures 11 and 12, and may be carried in other frames, or may be carried in other fields of the mapping negotiation request frame or the forced mapping frame, and the present application is not limited thereto.

[0096] Furthermore, after receiving the mapping negotiation request frame, the access point multilink device analyzes the forced field in the mapping negotiation request frame, and if the forced field carries first indication information (e.g., 1), this indicates that the station multilink device does not need to respond to the mapping negotiation request frame, and if the forced field does not carry first indication information, e.g., carries 0, this indicates that the station multilink device needs to respond to the mapping negotiation request frame. Or, after receiving the forced mapping frame, the access point multilink device analyzes the forced mapping field after the category field, which indicates that the station multilink device does not need to respond to the forced mapping frame.

[0097] In this application, the first indication message can explicitly indicate to the access point multilink equipment that it does not need to respond to the first indication message to the station multilink equipment, thereby reducing signaling overhead.

[0098] Example 3 The first instruction message may be an implicit instruction message. The following describes an example of the implicit instruction method.

[0099] For example, after receiving the first indication message, the access point multilink device obtains the updated first mapping information through analysis, and updates the second mapping information according to the same; and the access point multilink device can compare whether the uplink set corresponding to each traffic identifier is a non-empty subset of the first mapping link set between the station multilink device and the access point multilink device. If yes, determine that there is no need to respond to the first indication message to the station multilink device.

[0100] For example, as shown in FIG. 10, 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. As can be seen, after updating the mapping information, the uplink sets corresponding to TID1, TID2, and TID3 are non-empty subsets of the first mapping link sets corresponding to them, respectively. Based on this, the access point multilink device determines that it is not necessary to respond to the first indication message to the station multilink device.

[0101] The method of transmitting the first instruction message will be described below by taking an example.

[0102] FIG. 13 is a schematic diagram of a mapping negotiation request frame according to an embodiment of the present application. As shown in FIG. 13, the mapping negotiation request frame includes a mapping negotiation information element, which includes updated first mapping information but does not include first indication information. Furthermore, the mapping negotiation request frame may further include a category field, a mapping negotiation request field, and other fields, and the present application is not limited to other fields other than the mapping negotiation information element in the mapping negotiation request frame.

[0103] It should be understood that a mapping negotiation request frame is a type of action frame.

[0104] Illustratively, the category field may be filled with an EHT category.

[0105] In the present application, the first indication message can implicitly indicate to the access point multilink equipment that it does not need to respond to the first indication message to the station multilink equipment, thereby reducing signaling overhead.

[0106] Example 4 FIG. 14 is an interaction flowchart of another wireless communication method according to an embodiment of the present application. As shown in FIG. 14, the method includes the following steps:

[0107] In step S1410, the access point multilink device updates the third mapping information.

[0108] In step S1420, the access point multilink device generates a second indication message.

[0109] In step S1430, the access point multilink device sends a second indication message to the station multilink device.

[0110] In step S1440, the station multi-link device updates the fourth mapping information according to the updated third mapping information.

[0111] It should be understood that the third mapping information is mapping information from a traffic identifier to a downlink on the access point multilink device side.

[0112] It should be understood that the traffic identifiers in the third mapping information may be all downlink traffic identifiers of the access point multilink device, or may be the downlink traffic identifiers of the corresponding mapping information to be updated, and the present application is not limited thereto.

[0113] It should be understood that the traffic identifier in the third mapping information may be one or more, and if it is one, the third mapping information is mapping information from the traffic identifier to a downlink at the access point multilink device side, and if it is more than one, the third mapping information is mapping information from these more than one traffic identifier to a downlink at the access point multilink device side.

[0114] It should be understood that one traffic identifier may correspond or map to at least one link, for example, TID1 may map to link1 and link2, and TID2 may map to link1.

[0115] It should be understood that the access point multilink device can update the first mapping information in the above compression scenario.

[0116] 15 is a schematic diagram of updating mapping information from traffic identifiers to links according to an embodiment of the present application. As shown in FIG. 15, two links are established between the AP MLD and two station multilink devices STA MLD 1 and STA MLD 2, which are link 1 and link 2, respectively. In the initial state, for the above STA MLD 1 and STA MLD 2, TID1 and TID7 are all mapped to link 1 and link 2. For system optimization, for example, if STA MLD 2 has a large number of service flows of TID7 at this time, in order to ensure the service flow requirements of TID7 of STA MLD 2, the access point multilink device determines that link 2 is only used to transmit the service flow of TID7 according to the link state of STA MLD 2. For STA MLD 1, map TID1 and TID7 to link 1, and do not perform TID mapping for link 2. In this case, the AP MLD performs a remapping forced mode to update the mapping information from each TID to a link.

[0117] Exemplarily, the attached AP of the access point multilink device may send a second indication message to the attached station of the station multilink device.

[0118] Illustratively, the downlink corresponding to the attached station is in an active state.

[0119] Illustratively, the downlink corresponding to the attached AP is in an enabled state.

[0120] By way of example, but not limited to, the access point multi-link device may transmit the second indication message to the multiple station multi-link devices in an Orthogonal Frequency Division Multiple Access (OFDMA) manner.

[0121] It should be understood that the above second instruction message may be an implicit instruction message or an explicit instruction message, and the present application is not limited thereto.

[0122] It should be understood that the second indication message is used to instruct the station multilink device that it does not need to respond to the second indication message to the access point multilink device, i.e., the second indication message is used to instruct the station multilink device to adopt a remapping forced mode. Furthermore, the second indication message includes the updated third mapping information.

[0123] Exemplarily, the updated third mapping information includes mapping information from at least one traffic identifier to a corresponding downlink set.

[0124] It is noted that, when the traffic identifiers in the third mapping information are all the downlink traffic identifiers of the access point multilink device, the at least one traffic identifier may be all the downlink traffic identifiers of the access point multilink device.When the traffic identifiers in the third mapping information are the downlink traffic identifiers of the corresponding mapping information to be updated, the at least one traffic identifier may be all the downlink traffic identifiers of the corresponding mapping information to be updated.

[0125] Illustratively, 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 downlink set established between the station multilink device and the access point multilink device.

[0126] Illustratively, for any one traffic identifier among 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 second mapping link set between the station multilink device and the access point multilink device, where the second mapping link set is the downlink set corresponding to the traffic identifier before the third mapping information is updated.

[0127] Furthermore, after receiving the updated third mapping information, the station multi-link equipment updates the fourth mapping information, where the fourth mapping information is mapping information from the traffic identifier to the downlink at the station multi-link equipment side.

[0128] It should be understood that the traffic identifiers in the fourth mapping information may be all downlink traffic identifiers of the access point multilink device, or may be the downlink traffic identifiers of the corresponding mapping information to be updated, and the present application is not limited thereto.

[0129] It should be understood that the traffic identifier in the fourth mapping information may be one or more, and if it is one, the fourth mapping information is mapping information from the traffic identifier to a downlink at the station multilink equipment side, and if it is more than one, the fourth mapping information is mapping information from these more than one traffic identifier to a downlink at the station multilink equipment side.

[0130] It should be understood that before updating the third mapping information and the fourth mapping information, that is, at the initial stage, the third mapping information is the same as the fourth mapping information.

[0131] 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 traffic identifiers to links on the station multilink device side and the access point multilink device side are consistent.

[0132] In summary, in this application, a remapping forced mode can be adopted, that is, the station multilink device does not need to respond to the access point multilink device for the second indication message, thereby reducing signaling overhead.

[0133] As mentioned above, the second instruction message can be an implicit instruction message or an explicit instruction message, that is, the second instruction message can be an implicit method to instruct the station multilink device that it does not need to respond to the access point multilink device, or the second instruction message can be an explicit method to instruct the station multilink device that it does not need to respond to the access point multilink device. The following describes these two methods respectively.

[0134] Example 5 The second instruction message may be an explicit instruction message, for example, the second instruction message includes second instruction information, where the second instruction information is used to instruct the station multilink device that it does not need to respond to the second instruction message to the access point multilink device. The following takes an example to describe the manner of carrying the second instruction message.

[0135] In Example 1, Figure 16 is a schematic diagram of a mapping negotiation request frame according to an embodiment of the present application, as shown in Figure 16, 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. Exemplarily, the second indication information can be carried in a mandatory field in a control field of the mapping negotiation information element. In addition, the mapping negotiation request frame can further include a category field, a mapping negotiation request field, and other fields, and the present application is not limited to other fields other than the mapping negotiation information element in the mapping negotiation request frame.

[0136] It should be understood that a mapping negotiation request frame is a type of action frame.

[0137] Illustratively, the category field may be filled with an EHT category.

[0138] For example, the length of the second indication information may be 1 bit, where the second indication information may be 1, which indicates that the station multilink device does not need to respond to the second indication message to the access point multilink device. If the field in which the second indication information is located is not 1, for example, 0, it indicates that the station multilink device needs to respond to the second indication message to the access point multilink device.

[0139] It should be noted that the mapping negotiation request frame provided in FIG. 16 is an improvement to the mapping negotiation request frame in the prior art, in which the mapping negotiation request frame in the prior art does not have a forced field, and in the present application, the mapping negotiation request frame carries a forced field, which can be used to fill the second indication information.

[0140] In Example 2, Figure 17 is a schematic diagram of a forced mapping frame according to an embodiment of the present application, as shown in Figure 17, the forced mapping frame includes a forced mapping field and a mapping negotiation information element, the forced mapping field can be filled with second indication information, and the mapping negotiation information element includes updated third mapping information. In addition, the forced mapping frame can further include a category field and other fields, etc., and the present application is not limited to other fields in the forced mapping frame other than the mapping negotiation information element.

[0141] It should be understood that a mandatory mapping frame is a type of action frame.

[0142] Illustratively, the category field may be filled with an EHT category.

[0143] It should be noted that the difference between the forced mapping frame provided in FIG. 17 and the mapping negotiation request frame provided in FIG. 16 is that the forced mapping frame provided in FIG. 17 does not carry a forced field in the mapping negotiation information element.

[0144] It should be understood that the manner of carrying the second instruction information is not limited to the situation shown in Figures 16 and 17, and may be carried in other frames, or may be carried in other fields of the mapping negotiation request frame or the forced mapping frame, and the present application is not limited thereto.

[0145] Furthermore, after receiving the mapping negotiation request frame, the station multilink device analyzes the forced field in the mapping negotiation request frame, and if the forced field carries the second indication information (e.g., 1), this indicates that the access point multilink device does not need to respond to the mapping negotiation request frame, and if the forced field does not carry the second indication information, e.g., carries 0, this indicates that the access point multilink device needs to respond to the mapping negotiation request frame. Or, after receiving the forced mapping frame, the station multilink device analyzes the forced mapping field after the category field, which indicates that the station multilink device does not need to respond to the forced mapping frame.

[0146] In this application, the second indication message can explicitly indicate to the station multilink equipment that it does not need to respond to the second indication message to the access point multilink equipment, thereby reducing signaling overhead.

[0147] Example 6 The second instruction message may be an implicit instruction message. The following describes an implicit instruction manner by taking an example.

[0148] For example, after receiving the second indication message, the station multilink device obtains the updated third mapping information through analysis, and updates the fourth mapping information according to the obtained information; further, the station multilink device can compare whether the downlink set corresponding to each traffic identifier is a non-empty subset of the second mapping link set between the station multilink device and the access point multilink device. If yes, determine that there is no need to respond to the second indication message to the access point multilink device.

[0149] The method of transmitting the second instruction message will be described below by taking an example.

[0150] FIG. 18 is a schematic diagram of a mapping negotiation request frame according to an embodiment of the present application. As shown in FIG. 18, the mapping negotiation request frame includes a mapping negotiation information element, which includes updated third mapping information but does not include second indication information. Furthermore, the mapping negotiation request frame may further include a category field, a mapping negotiation request field, and other fields, and the present application is not limited to other fields other than the mapping negotiation information element in the mapping negotiation request frame.

[0151] It should be understood that a mapping negotiation request frame is a type of action frame.

[0152] Illustratively, the category field may be filled with an EHT category.

[0153] In the present application, the second indication message can implicitly indicate to the station multilink equipment that it does not need to respond to the second indication message to the access point multilink equipment, thereby reducing signaling overhead.
