One case of association is that the stations directly communicate with each other in an ad hoc network, which is referred to as an independent BSS (IBSS). Another more common case is that in a BSS network, there is only one central station with a full-time management BSS, referred to as an access point device, and other STAs in the network are associated with it. Other stations in the BSS network that are not central stations are referred to as terminals, also referred to as non-AP STAs. When describing STAs, it is not necessary to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, and the like, a STA cannot detect other STAs that are far away from it, and the two are each other's hidden nodes.

[0116] The second padding field includes: a second padding delay required for a second non-AP STA affiliated to a second non-AP MLD for the last time to send a switch enhanced multi-link single radio EMLSR link.

[0117] Preferably, the first non-AP STA is a device supporting UHR transmission protocol, the second non-AP STA is a device supporting Extremely High Throughput (EHT) transmission protocol; and the AP MLD at least comprises a first AP operating at a first channel and having a working bandwidth of 20 MHz.

[0118] In the WLAN, power saving (PS) is a research focus, and considering that some STAs have limited receiving capability, an Enhanced Multi-link Single Radio (EMLSR) mode is introduced. In the EMLSR mode, a non-AP MLD can enter a listening operation on multiple links simultaneously. In the listening operation, the non-AP MLD uses a single antenna (for example, one antenna) to receive on each link. After an AP MLD successfully transmits an initial control frame (ICF) to the non-AP MLD on any link (for example, link 1), the non-AP MLD can switch all spatial streams on the links to link 1 to perform frame interaction with the AP MLD, and at this time, there are multiple spatial streams / antennas on link 1. After the frame interaction ends, the non-AP MLD switches the spatial streams on link 1 back to the links and returns to the listening operation, that is, the non-AP MLD switches the spatial streams on link 1 switched from link 2 back to link 2 to perform the listening operation, and at this time, there is one spatial stream / antenna on each of link 1 and link 2.

[0119] In the embodiments of the present disclosure, the initial control frame is, for example, a Multi User-Request To Send (MU-RTS) frame or a Buffer Status Report Poll (BSRP) frame, or other frames.

[0120] In the embodiments of the present disclosure, as an example, referring to FIG. 3, there are three MLDs in the networking environment, which are an AP MLD supporting UHR transmission protocol, a first non-AP MLD supporting UHR transmission protocol, and a second non-AP MLD supporting EHT transmission protocol. Among them, the AP MLD at least includes a first AP (AP1 in FIG. 3) working in a first channel with a working bandwidth of 20 MHz and other APs; the first non-AP MLD includes a first non-AP STA (STA1-1 in FIG. 3) and other non-AP STAs, and the second non-AP MLD includes a second non-AP STA A (STA2-1 in FIG. 3) and other non-AP STAs.

[0121] Among them, the first AP is connected with STA1-1 and STA2-1 through link 1 (link1 in FIG. 3) and link 3 (link3 in FIG. 3) respectively.

[0122] The AP MLD determines an initial control frame, which can be used to wake up UHR devices and trigger EHT devices; wherein the initial control frame includes target padding delay information, so that the non-AP MLD has enough time to switch its working link or power consumption state after receiving the initial control frame. The padding delay information indicates the time used for switching from a single spatial stream (or a single antenna) on one link to a multi-spatial stream (or multi-antenna) on another link. The non-AP MLD can start switching after receiving the content part of the initial control frame, and only needs to complete the switching before the arrival of the subsequent data frame. It can be understood that the longer the switching delay required by the non-AP MLD, the more padding bits need to be added in the initial control frame, that is, the more bits of the padding field of the target padding delay information.

[0123] Among them, the length of the padding field corresponding to the target padding delay information is the larger value (that is, the padding field has more bits) in the first padding field and the second padding field;

[0124] The first padding field includes: a first padding delay required by a first non-AP STA affiliated to a first non-AP MLD to switch from a first capabilities mode to a second capabilities mode, for example, a padding delay required by STA1-1 to switch from a low capabilities mode to a high capabilities mode (or a full capabilities mode) in FIG. 3; at least one working parameter of the first non-AP STA, which is lower in the first capabilities mode than in the second capabilities mode; it can be understood that in the embodiments of the present disclosure, the "capabilities mode" is equivalent to the "capabilities state", and in some embodiments, the two can be interchangeable.

[0125] Specifically, at least one working parameter of the first capabilities mode is lower than the second capabilities mode, and the working parameter is, for example, bandwidth, spatial stream (SS), modulation and coding scheme (MCS) mode, and the like.

[0126] The communication parameter type of the first and second capability modes can be the same, and at least one working parameter of the first capability mode is lower than that of the second capability mode. For example, the first capability mode can also be a listening state or a low-power communication stage, and the working parameter is, for example, a 20MHz basic bandwidth, the number of SS is 1, and the MCS mode is, for example, from MCS0 to MCS7. The working parameter of the second capability mode is, for example, greater than or equal to 20MHz, the BW can also be 40 / 80 / 160(80+80) / 320MHz, the number of SS is greater than or equal to 2, and the MCS mode is, for example, from MCS6 to MCS14, and the like. Specifically, under certain conditions, a UHR device in a dynamic power saving (DPS) mode will enter a low-power listening (LPL) mode. In the LPL mode, for example, a single spatial stream, a 20MHz bandwidth, and a low-rate MCS are used for transceiving. When an AP MLD needs to communicate with it, the affiliated AP is scheduled to actively send an ICF frame to trigger the corresponding non-AP STA to enter a full-capability (or high-capability) mode. The second padding field includes a second non-AP STA affiliated to a second non-AP MLD and a second padding delay required for the last time to send a switching EMLSR link. For example, after STA2-1 completes initial association with AP1, the padding delay required for switching the EMLSR link is reported. The second padding delay can be initially reported by the second non-AP STA through an Association Request frame, or subsequently updated through an EML Operating Mode Notification frame.

[0127] In the embodiments of the present disclosure, the AP MLD carries a padding field in the ICF frame, which is used to wait for the STA to switch the EMLSR link and the power consumption state. After the STA completes the switching, the STA can reply with an ICF Response frame to indicate that the state switching is completed. Then, the affiliated AP and the STA perform PPDU data interaction again. After the data interaction is completed, the STA resumes the LPL mode. In the embodiments of the present disclosure, the length of the padding field corresponding to the target padding delay information is the larger one of the first padding field and the second padding field. The first padding field is the first padding delay required for the first non-AP STA affiliated to the first non-AP MLD to switch from the first capability mode to the second capability mode. The second padding field is the second padding delay required for the last time of the second non-AP STA to send the switching EMLSR link. In this way, in the padding field corresponding to the target padding delay information, the EHT STA can complete the EMLSR link switching, and the UHR STA can complete the power consumption state switching (or the communication parameter switching), for example, switching from a low capability state to a high capability state. In this way, it is avoided that the spatial stream switching of the EHT STA is not completed due to that the padding time in the initial control frame is too short, and the data transmission is started, resulting in the PPDU packet loss at the EHT device side.

[0128] In step 202, the AP MLD sends the initial control frame to the first non-AP MLD and / or the second non-AP MLD.

[0129] In step 202, the AP MLD sends the initial control frame to the first non-AP MLD and / or the second non-AP MLD.

[0130] In this way, in the padding field corresponding to the target padding delay information, the EHT STA completes the EMLSR link switching, and the UHR STA completes the power consumption state switching (or communication parameter switching), such as switching from a low-capability state (or LPL state) to a high-capability state (or full-capability state), so that the situation that the spatial stream switching of the EHT STA is not completed and data transmission is started, and PPDU packet loss occurs at the EHT device side due to too short padding time in the initial control frame is avoided. The power consumption state switching time of the UHR STA and the EMLSR link switching time of the EHT STA are considered at the same time, and the problem that the UHR device cannot interact with the EHT STA after being woken up is avoided, the power saving wake-up requirement of the UHR STA is met, and the link switching requirement of the EHT STA in the EMLSR link is also compatible.

[0131] In some embodiments, as shown in FIG. 4, before the foregoing step 201, the method further includes:

[0132] In step 401, the AP MLD receives a first EML Operating Mode Notification frame or a first wireless frame sent by the first non-AP STA (or first non-AP MLD); the EML Operating Mode Notification frame or the first wireless frame carries the first padding delay; the first wireless frame is a wireless frame sent in an association completion or multi-link establishment process, such as an Association Request frame.

[0133] In the foregoing embodiment, the UHR non-AP MLD (first non-AP MLD) reports the padding delay required for EMLSR link switching when establishing a connection with the AP MLD. For example, STA1-1 is connected to AP1, and reports the padding delay required for EMLSR link switching through an Association Request.

[0134] Alternatively, after the association is completed, the Padding delay is updated through the first EML Operating Mode Notification frame. For example, when the UHR non-AP MLD (the first non-AP MLD) establishes a connection with the AP MLD, the Padding delay required for switching the EMLSR link is periodically reported through the first EML Operating Mode Notification frame. For example, STA1-1 is connected to AP1, and the Padding delay required for switching the EMLSR link is reported through the EML Operating Mode Notification frame.

[0135] In some embodiments, as shown in FIG. 5, before the foregoing step 201, the method further comprises:

[0136] Step 501, receiving the association request frame and / or the second EML Operating Mode Notification frame sent by the second non-AP MLD; wherein the association request frame or the second EML Operating Mode Notification frame includes the second padding delay.

[0137] Wherein, when the second non-AP MLD establishes a connection with the AP MLD, the Padding delay required for switching the EMLSR link is reported through the Association Request frame; for example, STA2-1 is connected to AP1, and the Padding delay required for switching the EMLSR link is reported through the Association Request when establishing a connection.

[0138] Alternatively, after the association is completed, the Padding delay is updated through the second EML Operating Mode Notification frame. For example, when the EHT non-AP MLD (the second non-AP MLD) establishes a connection with the AP MLD, the Padding delay required for switching the EMLSR link is periodically reported through the second EML Operating Mode Notification frame. For a STA, for example, the second non-AP STA, the Padding delay last reported by it is taken as the second padding delay.

[0139] In some embodiments, as shown in FIG. 6, after step 202, the method further comprises:

[0140] In step 203, the AP MLD receives a first CTS frame sent by the first non-AP STA; the first CTS frame identifies that the first non-AP STA is switched from the first capability mode to the second capability mode and waits for data transmission.

[0141] and / or

[0142] In step 204, the AP MLD receives a second CTS frame sent by the second non-AP STA; the second CTS frame identifies that the second non-AP STA waits for data transmission.

[0143] In step 203, in combination with FIG. 3, after STA1-1 of the UHR STA MLD receives the ICF frame, it switches to Higher Capabilities and replies with a first clear to send (CTS) frame, indicating that STA1-1 has completed the state switching and waits for subsequent data transmission.

[0144] In step 204, in combination with FIG. 3, after STA2-1 of the EHT STA MLD receives the ICF frame, it replies with a second CTS frame according to whether it can receive / transmit data, indicating that it waits for subsequent data transmission.

[0145] In some embodiments, the method further comprises:

[0146] The AP MLD sends a Multi-User Physical Layer Protocol Data Unit (MU PPDU) data frame to the first non-AP MLD and / or the second non-AP MLD.

[0147] After receiving the first CTS frame, the AP MLD sends a MU PPDU data frame to the first non-AP MLD, and STA1-1 can also send a Trigger-Based PPDU (TB PPDU) to complete data transmission.

[0148] After receiving the second CTS frame, the AP MLD sends a MU PPDU data frame to the second non-AP MLD, and STA2-1 can also send a TB PPDU to complete data transmission.

[0149] The embodiments of the present disclosure provide a power saving wake-up scheduling method when a UHR device coexists with an EHT device. When a qualified UHR device and an EHT device simultaneously access a UHR AP MLD, a reasonable comparison and selection are made by using the reported padding delay, so as to avoid the situation that the EHT STA is not ready for data reception when the UHR AP sends a data packet, and ensure the compatibility and availability of the power saving feature.
