In 802.11be, a function capable of supporting 802.11 multilink is defined. According to the definition of the two ends of the communication in 802.11, one is the station STA multi-link device (Multiple Links Device, MLD), and the other is the access point (Access Point, AP) MLD device. The STA MLD and AP MLD that have established multi-links can take advantage of multi-links to send and receive data on multiple links to achieve high throughput and low latency.

At the same time, in 802.11be, in order to make better use of the advantages of multi-link on some low-cost STA MLD devices, enhanced multiple link single radio (enhanced Multiple Link Single Radio, eMLSR) and enhanced multi-link Enhanced Multiple Link Multiple Radio (eMLMR) two mechanisms. The following takes the establishment of two links between AP MLD and STA MLD as an example to illustrate the mechanisms of eMLSR and eMLMR.

The working mechanism of eMLSR is as follows. When STA MLD and AP MLD enable eMLSR mode (mode), the downlink (Down Link, DL) transmission will include two stages:

1) Initial control frame exchange phase (Initial Control frame exchange Phase):

At this stage, STA MLD and AP MLD will transmit frames with a limited link capability (Link Capability). ), the data rate (data rate) corresponding to the modulation method used is relatively low, and so on. And, at this stage, STA MLD can work on both links simultaneously.

2) Normal frame exchange Phase (Normal frame exchange Phase):

At this stage, STA MLD can only work on one link, and the link capacity between STA MLD and AP MLD can be higher than that in the initial control frame interaction stage. At this stage, the link on which STA MLD can work is determined by the behavior of the initial control frame interaction stage. Please refer to FIG. 2 , which shows a schematic diagram of downlink transmission involved in the present application. As shown in FIG. 2 , the link where the initial control frame interaction succeeds is the link where the normal frame interaction phase is located. And, the duration of this phase is a frame exchange sequence.

Figure 2 shows the downlink transmission process of an eMLSR. First, the AP MLD will select a link (Link1) for the initial control frame interaction process. After the initial control frame interaction is successful, the STA MLD will switch to a higher link on Link1. Link capability for transmission, for example, switch to higher spatial stream and/or higher modulation and coding strategy (Modulation and Coding Scheme, MCS) and/or higher operating bandwidth, etc., while not working on Link2. After AP MLD and STA MLD complete a frame exchange sequence with a higher link capability on Link1, STA MLD needs to switch to a lower link capability again to work on Link1 and Link2 at the same time.

The mechanism of eMLMR is similar to that of eMLSR, and the DL downlink transmission is also divided into the Initial Control Frame exchange stage and the Normal frame exchange stage. Moreover, STA MLD can work on two links at the same time during the Initial Control Frame exchange phase, but the link capability on these two links is a low link capability (such as lower spatial flow capability); STA MLD In the Normal frame exchange stage, only one link can work, and a higher link capacity is used. The switching process of the two phases of eMLMR is similar to the switching process of eMLSR; the working link in the Normal frame exchange phase is also determined by the Initial Control Frame exchange phase. The duration of the Normal frame exchange phase is also a frame exchange sequence.

The difference between eMLMR and eMLSR can include that the types of data frames allowed to be sent and received during the Initial Control Frame Exchange phase are different. For example, in eMLSR, the Initial Control Frame Exchange stage only allows sending and receiving control frames with low modulation orders and/or single spatial streams, while in eMLMR, higher modulation orders and/or multiple spatial streams can be allowed Interaction with dataframes.

Under the relevant mechanism, the duration of the Normal frame exchange phase between STA MLD and AP MLD is determined by whether a frame exchange sequence (frame exchange sequence) is completed. Please refer to Figure 3, which shows a schematic diagram of a stage end judgment involved in this application. As shown in Figure 3, a common method for STA MLD to judge whether the frame exchange sequence It is detected that the channel state is idle (Idle) for a duration exceeding a certain threshold, usually this threshold is the priority frame interval (Priority Inter Frame Space, PIFS), such as 25us.

Based on the stage end judging process shown in FIG. 3 , please refer to FIG. 4 , which shows a schematic diagram of downlink transmission involved in this application. As shown in Figure 4, the scheme shown in Figure 3 has the following shortcomings in judging the duration of the Normal frame exchange phase:

During the downlink Normal frame exchange phase of AP MLD, when STA MLD does not correctly receive the downlink data frame of AP MLD, AP MLD will not receive the corresponding acknowledgment frame (Acknowledgment) from STA MLD, and AP MLD may adopt a retransmission strategy , but when the AP MLD selects the retransmission time point, the AP MLD will first judge that the Acknowledgment confirmation frame has not been received (that is, the AP MLD has not received the confirmation frame within a certain period of time (Ack Timeout) after sending the DL data frame), Channel access will then be re-executed.

In Figure 4, because there is a mismatch between the STA MLD and the AP MLD in judging whether the frame exchange sequence is over, the AP MLD cannot choose to use the correct Link Capability to transmit downlink frames to the STA MLD, making the STA MLD DL downlink frame of AP MLD cannot be received correctly. For example, at this time, STA MLD believes that the Normal Frame exchange Phase has ended, so it can only receive the downlink data frame of one spatial stream on Link1, but at this time, the AP MLD believes that the Normal Frame exchange Phase has not ended, and will continue to communicate with Link1. STA MLD sends downlink data frames of two spatial streams, which causes STMLD to fail to receive these downlink data frames correctly.

Please refer to FIG. 5 , which shows a schematic diagram of downlink transmission involved in this application. As shown in Figure 5, when the AP MLD fails to correctly receive the Acknowledgment confirmation frame sent by the STA MLD in the downlink Normal frame exchange, the AP MLD may also adopt a retransmission strategy, so that the STA MLD shown in Figure 3 will also appear The judgment of whether the frame exchange sequence ends does not match with the AP MLD.

For the above problems, a subsequent embodiment of the present application proposes a scheme in which the STA MLD and the AP MLD interact to determine a unified criterion for judging the end of the downlink Normal frame exchange phase.

Fig. 6 is a flow chart showing a frame interaction control method according to an exemplary embodiment. The frame interaction control method may be executed by a station multi-link device. For example, the station multi-link device may be the one shown in Fig. 1 The terminal device 110 in the implementation environment. As shown in Fig. 6, the method may include the following steps.

Step 601, interacting with the access point multi-link device for phase control information, where the phase control information is used to indicate the end condition of the downlink normal frame interaction phase.

In this embodiment of the present application, before a downlink normal frame interaction phase is performed between the station multi-link device and the access point multi-link device, or during a downlink normal frame interaction phase, the station multi-link device and the access point multi-link device Interaction of phase control information can be performed between the multi-link devices of the access point, so as to define a unified downlink normal frame interaction phase end judgment condition between the multi-link device of the station and the multi-link device of the access point.

Step 602: During the downlink normal frame interaction process with the access point multi-link device, when the end condition is met, end the downlink normal frame interaction phase with the access point multi-link device.

The station multi-link device is in the process of the downlink normal frame interaction between the access point multi-link device, and can judge the downlink normal frame through the unified stage end judgment condition in the station multi-link device and the access point multi-link device Whether the interaction phase is over.

To sum up, in the embodiment of this application, phase control information can be exchanged between the site multi-link device and the access point multi-link device to determine the end condition of the downlink normal frame interaction phase, so that the site multi-link The road device can use the end condition unified with the access point multi-link device to judge whether the downlink normal frame interaction phase with the access point multi-link device is over, so as to avoid the occurrence of site multi-link devices and access point multi-link The end time of the normal frame interaction stage of the road device is inconsistent, reducing the transmission error between the multi-link device of the site and the multi-link device of the access point, thereby improving the utilization rate of air interface resources.

Fig. 7 is a flow chart showing a frame interaction control method according to an exemplary embodiment, the frame interaction control method may be executed by an access point multi-link device, for example, the access point multi-link device may be 1 shows the access point device 120 in the implementation environment. As shown in Fig. 7, the method may include the following steps.

Step 701, interacting with the station multi-link device for phase control information, where the phase control information is used to indicate the end condition of the downlink normal frame interaction phase.

Step 702: During the downlink normal frame interaction process with the site multi-link device, when the end condition is met, end the downlink normal frame interaction phase with the site multi-link device.

To sum up, in the embodiment of this application, the phase control information interaction can be performed between the access point multi-link device and the station multi-link device to determine the end condition of the downlink normal frame interaction phase, so that the access point The multi-link device can use the end condition unified with the site multi-link device to judge whether the downlink normal frame interaction phase with the site multi-link device is over, avoiding the occurrence of site multi-link devices and access point multi-link devices The judgment of the end time of the normal frame interaction phase is inconsistent, reducing the transmission error between the site multi-link device and the access point multi-link device, thereby improving the utilization of air interface resources.

In a possible implementation manner of the present application, the above end condition may be configured by the access point multi-link device to the station multi-link device.

Fig. 8 is a flow chart showing a frame interaction control method according to an exemplary embodiment. The frame interaction control method may be executed interactively between an access point multi-link device and a station multi-link device, for example, the station The multi-link device may be the terminal device 110 in the implementation environment shown in FIG. 1 , and the access point multi-link device may be the access point device 120 in the implementation environment shown in FIG. 1 . As shown in Figure 8, the method may include the following steps.

Step 801, the access point multi-link device sends phase control information to the station multi-link device; correspondingly, the station multi-link device receives the phase control information; the phase control information is used to indicate the end condition of the downlink normal frame interaction phase.

In the embodiment of the present application, the access point multi-link device may directly notify the station multi-link device of the end condition of the downlink normal frame interaction phase through the phase control information.

In a possible implementation manner, the access point multi-link device may send phase control information to the station multi-link device during the initial control frame interaction stage with the station multi-link device. Correspondingly, the station multi-link device receives the phase control information sent by the access point multi-link device during the initial control frame interaction phase with the access point multi-link device.

In this embodiment of the application, during the process of initial control frame interaction between the access point multi-link device and the station multi-link device, one or more downlink The end condition of the normal frame interaction phase is notified to the station multi-link device.

In a possible implementation manner, the phase control information includes the duration of the downlink normal frame interaction phase; or, the phase control information includes an end time point of the downlink normal frame interaction phase.

In the embodiment of the present application, the end condition of the above-mentioned downlink normal frame interaction phase may be a condition related to the end time point of the downlink normal frame interaction phase, and correspondingly, the phase control information includes the end time of the downlink normal frame interaction phase Point-related time information; wherein, the end time point of the downlink normal frame interaction phase may be a time point that has been determined before the downlink normal frame interaction phase.

For example, the time information may be a duration that indirectly indicates the end time point of the downlink normal frame interaction phase, that is, the duration of the downlink normal frame interaction phase; or, the time information may also be the end of the downlink normal frame interaction phase point in time.

In a possible implementation manner, the phase control information is an initial control frame. In other words, the control information at this stage is carried by the initial control frame.

Wherein, during the process of initial control frame interaction between the access point multi-link device and the station multi-link device, the access point multi-link device may send the initial control frame to the station multi-link device. Optionally, the station The multi-link device can return a Clear To Send (CTS) response frame to the multi-link device of the access point to interactively determine information such as the link used in the subsequent downlink normal frame interaction phase. In this embodiment of the present application, the access point multi-link device may multiplex the initial control frame to indicate the termination condition of the downlink normal frame interaction phase. For example, the duration or end time of the downlink normal frame interaction phase may be carried through a reserved field in the initial control frame. Alternatively, the solution shown in the embodiment of this application can also improve the frame structure of the initial control frame, add a field to the initial control frame, and use the added field to carry the duration or end time of the above-mentioned downlink normal frame interaction phase point.

In another possible implementation, during the process of initial control frame interaction between the multi-link device of the access point and the multi-link device of the station, the multi-link device of the access point may also create a new A downlink frame is added as the above-mentioned stage control information. That is to say, in this embodiment of the application, during the initial control frame interaction phase, the multi-link device of the access point may carry the duration or end time of the above normal downlink frame interaction phase through other downlink frames other than the initial control frame .

In another possible implementation manner, the access point multi-link device may also send phase control information to the station multi-link device at a time point other than the initial control frame interaction phase. For example, when the downlink normal frame interaction phase starts, phase control information is sent to the station multi-link device; optionally, the phase control information may be a new downlink frame in the downlink normal frame interaction phase.

Step 802: In the process of the downlink normal frame interaction between the station multi-link device and the access point multi-link device, if the end condition is satisfied, end the downlink normal frame interaction with the access point multi-link device stage.

In a possible implementation, when the above end condition is a condition related to the end time point of the downlink normal frame interaction phase, the station multi-link device performs the process of downlink normal frame interaction with the access point multi-link device , if the current time reaches or exceeds the end time point of the downlink normal frame interaction phase, the downlink normal frame interaction phase with the access point multi-link device ends.

In this embodiment of the application, after the end condition notified by the station multi-link device through the access point multi-link device through the phase control information, the end time of the current downlink normal frame interaction phase can be directly or indirectly indicated by the end condition point to determine whether the current downlink normal frame interaction phase is over.

Wherein, when the phase control information directly includes the end time point of the downlink normal frame interaction phase, the site multi-link device can directly compare the end time point contained in the phase control information with the current time, and if the current time reaches or If the end time point of the downlink normal frame interaction phase is exceeded, the downlink normal frame interaction phase with the access point multi-link device ends; or, before the end time point of the downlink normal frame interaction phase arrives, the station multi-link device A timer can be set according to the end time point of the downlink normal frame interaction phase. The timer reaches its timing duration at the end time point of the downlink normal frame interaction phase. The timer is used to trigger the site multi-link when the timing duration is reached. The device ends the downlink normal frame interaction phase with the multi-link device of the access point.

In a possible implementation, when the phase control information includes the duration of the downlink normal frame interaction phase, the site multi-link device obtains the downlink normal frame interaction phase according to the duration and the start time point of the downlink normal frame interaction phase The end time point of the stage.

In this embodiment of the present application, when the phase control information indirectly indicates the end time point of the downlink normal frame interaction phase through the duration of the downlink normal frame interaction phase, the site multi-link device can firstly use the duration of the downlink normal frame interaction phase time, and a start time point of the downlink normal frame interaction phase known by the station multi-link device and the access point multi-link device to determine the end time point of the downlink normal frame interaction phase.

In a possible implementation manner, the start time point of the downlink normal frame interaction phase is the end time point of the initial control frame in the initial control frame interaction phase;

Alternatively, the start time point of the downlink normal frame interaction phase is the end time point of the response frame of the initial control frame in the initial control frame interaction phase.

In this embodiment of the application, the start time point of the downlink normal frame interaction phase known by the station multi-link device and the access point multi-link device may be the end of a specific frame in the initial control frame interaction phase The time point, for example, can be the end time point of the initial control frame Initial Control frame sent by the access point multi-link device, or it can also be the response frame (such as CTS frame) of the station multi-link device to the above-mentioned initial control frame end time point of .

Optionally, the start time point of the above-mentioned downlink normal frame interaction phase may also be other time points other than the end time point of a specific frame in the initial control frame interaction phase, for example, it may be a time point in the initial control frame interaction phase The start time point of a specific frame, or, it can also be the time point obtained by delaying or advancing the end time point of a specific frame in the initial control frame interaction phase, etc., only the downlink normal frame is required The starting time point of the interaction phase is only known by the station multi-link device and the access point multi-link device.

In a possible implementation manner, the above-mentioned stage control information may also include a switching delay time, and the switching delay time is used to indicate a time delay for switching from the downlink normal frame interaction stage to the initial control frame interaction stage.

In the embodiment of the present application, the above end condition may also be a condition related to the frame interaction in the downlink normal frame interaction phase. For example, the control information of this phase may include a switching delay time, which may be different from the normal downlink frame interaction time. The time points corresponding to the specific frame interaction events in the frame interaction phase are used in combination to determine whether the current downlink normal frame interaction phase is over.

In a possible implementation manner, in the process of downlink normal frame interaction with the access point multi-link device, if the end condition is met, the station multi-link device terminates the communication with the access point multi-link device The process of the downlink normal frame interaction phase may include:

In the process of downlink normal frame interaction with the multi-link device of the access point, if the time length between the current time and the target time point is not less than the handover delay time, and/or, the time between the current time point and the target time point is not successfully completed At least one frame interaction with the access point multi-link device ends the downlink normal frame interaction phase with the access point multi-link device.

In the embodiment of the present application, the above target time point is a time point known to both the station multi-link device and the access point multi-link device during the normal downlink frame interaction process. For example, the target time point is a time point corresponding to a specific event known by the station multi-link device and the access point multi-link device in the process of downlink normal frame interaction. The station multi-link device can start timing from the target time point. If the timing reaches the handover delay time, and at least one frame interaction with the access point multi-link device is not completed during the timing, the station multi-link device The device can end the downlink normal frame interaction phase with the multi-link device of the access point.

In a possible implementation manner, the target time point is an end time point of a downlink frame in the latest successful frame interaction with the access point multi-link device.

In this embodiment of the present application, the completion of a frame interaction between the station multi-link device and the access point multi-link device can be considered as a specific event, and the target time point can be the time point between the station multi-link device and the access point The end time point of the downlink frame in the last completed frame exchange between multi-link devices. For example, if the site multi-link device interacts with the access point multi-link device in the process of downlink normal frame interaction, if it does not receive a downlink frame, it can start timing from the time when the reception is completed. If the timing reaches the handover delay time , and at least one frame interaction with the access point multi-link device is not completed during the timing process, the station multi-link device may end the downlink normal frame interaction phase with the access point multi-link device.

Optionally, the above target time point may also be a time point other than the end time point of the downlink frame in the latest successful frame interaction during the normal downlink frame interaction process. For example, the above target time point may be the last successful The end time point of the response frame corresponding to the downlink frame in the frame interaction (for example, the CTS frame fed back by the station multi-link device for the downlink frame), and so on.

In step 803, the access point multi-link device ends the normal downlink frame interaction phase with the station multi-link device when the end condition is met during the process of interacting with the station multi-link device.

In a possible implementation, when the access point multi-link device interacts with the downlink normal frame with the station multi-link device, if the current time reaches or exceeds the end time point of the downlink normal frame interaction phase, the The downlink normal frame interaction phase with the site multi-link device.

In a possible implementation, when the phase control information includes the duration of the downlink normal frame interaction phase, the access point multi-link device obtains the The end time point of the downlink normal frame interaction phase.

In a possible implementation manner, the phase control information includes a switching delay time, and the switching delay time is used to indicate a time delay for switching from the downlink normal frame interaction phase to the initial control frame interaction phase.

In a possible implementation, in the process of downlink normal frame interaction with the station multi-link device, if the time length between the current moment and the target time point is not less than the handover delay time, and/or, the current moment and the target time point If at least one frame interaction with the site multi-link device is not successfully completed between the time points, the downlink normal frame interaction phase with the site multi-link device ends.

In a possible implementation manner, the target time point is the end time point of the downlink frame in the latest successful frame interaction with the station multi-link device.

Wherein, the process in which the access point multi-link device side judges whether the current downlink normal frame interaction phase is over by the end condition is the same as the process in which the station multi-link device side judges whether the current downlink normal frame interaction phase is over by the end condition in step 802 The process is similar and will not be repeated here.

In the embodiment of the present application, since a unified end condition is used between the access point multi-link device and the station multi-link device to determine whether the current downlink normal frame interaction phase is over, correspondingly, in order to avoid downlink frame transmission errors, the On the multi-link device side of the access point, the end condition also needs to constrain the sending behavior of the downlink frame.

In a possible implementation, when the access point multi-link device interacts with the downlink normal frame with the station multi-link device, when the end time of the target downlink frame does not exceed the end time of the downlink normal frame interaction phase When point, send the target downlink frame;

Or, when the access point multi-link device interacts with the downlink normal frame with the station multi-link device, when the end time point of the reply confirmation frame corresponding to the target downlink frame does not exceed the end time point of the downlink normal frame interaction phase , to send the target downlink frame.

That is to say, in this embodiment of the application, when the end condition is a condition related to the end time point of the downlink normal frame interaction phase, if there is a downlink frame to be sent in the multi-link device of the access point, the access point Before the multi-link device sends the downlink frame, it can first judge whether the end time point of the downlink frame or the end time point of the response frame corresponding to the downlink frame (that is, the above-mentioned reply confirmation frame) does not exceed the normal frame interaction phase. End time point, if yes, then send the downlink frame, so as to ensure that the downlink frame or the reply confirmation frame of the downlink frame can be transmitted before the end of the normal frame interaction phase.

In a possible implementation, when the multi-link device of the access point interacts with the downlink normal frame with the multi-link device of the station, between the end time point of the target downlink frame and the end time of the last downlink frame sent When the duration between the points does not exceed the switching delay time, the target downlink frame is sent;

Or, when the access point multi-link device interacts with the downlink normal frame with the station multi-link device, the end time point of the reply confirmation frame corresponding to the target downlink frame is different from the end time point of the last downlink frame sent. When the duration between them does not exceed the handover delay time, the target downlink frame is sent.

That is to say, in the embodiment of the present application, when the end condition is a condition related to a time point corresponding to a specific event in the downlink normal frame interaction phase, if there is a downlink that needs to be sent in the multi-link device of the access point frame, before the access point multi-link device sends the downlink frame, it can first judge the end time point of the downlink frame and the time point corresponding to the specific event (that is, the end time point of the above-mentioned target downlink frame or the reply corresponding to the target downlink frame Confirm whether the duration between the end time of the frame) does not exceed the above switching delay time, if so, it means that the downlink frame can be transmitted before the end of the normal frame interaction phase, and the downlink frame can be sent at this time, otherwise the downlink frame will not be sent frame.

In the Initial Control Frame exchange phase of the AP MLD, the Initial control frame sent by the AP MLD to the STA MLD can carry information indicating the duration/end time point of the Normal frame exchange Phase. Related information can be carried in the following two ways.

1) The Initial Control Frame of AP MLD carries the duration of Normal frame exchange Phase. For example, please refer to FIG. 9 , which shows a schematic diagram of judging the end of the downlink normal frame interaction phase involved in the embodiment of the present application. As shown in Figure 9, the starting point of this Duration can be selected at the end point of the initial control frame of AP MLD.

2) The Initial Control Frame of the AP MLD carries the end time point of the Normal frame exchange Phase (it can be a timestamp timestamp). For example, please refer to FIG. 10 , which shows a schematic diagram of judging the end of the downlink normal frame interaction phase involved in the embodiment of the present application. As shown in Figure 10, the Initial Control Frame directly indicates the end time of the Normal frame exchange Phase.

In this solution, when the AP MLD expects to use the link capability of the Normal Frame Exchange Phase to send frames to the STA MLD, the following two conditions need to be checked.

A) The duration of the frame to be sent does not exceed the end time of the Normal Frame Exchange Phase.

B) The duration of the frame to be sent plus the expected STA MLD reply confirmation frame does not exceed the end time of the Normal Frame Exchange Phase.

When at least one of the above conditions is met, the AP MLD can use the link capability of the Normal Frame Exchange Phase to send the corresponding downlink frame to the STA MLD.

Please refer to FIG. 11 and FIG. 12 , which show two schematic diagrams of multi-link transmission involved in this embodiment of the present application. Taking the AP MLD in the downlink Normal frame exchange, the STA MLD does not correctly receive the DL data of the AP MLD (that is, the downlink frame) as an example, through the solution shown in the embodiment of this application, as shown in Figure 11, when the AP MLD judges that When the DL physical layer protocol packet unit (Physical Protocol Data Unit, PPDU) interaction that needs to be retransmitted does not exceed the normal frame exchange phase negotiation end time, you can continue to retransmit the DL to the STA MLD with the link capability of the normal frame exchange phase PPDU; as shown in Figure 12, when the AP MLD judges that the DL PPDU interaction that needs to be retransmitted will exceed the negotiation end time of the Normal Frame Exchange Phase, the AP MLD will give up retransmitting the DL PPDU and wait for the Normal Frame Exchange Phase. Finish.

To sum up, in the embodiment of this application, the access point multi-link device can notify the station multi-link device of the end condition of the downlink normal frame interaction phase through the phase control information, so that the access point multi-link device The end condition unified with the site multi-link device can be used to judge whether the downlink normal frame interaction phase with the site multi-link device is over, so as to avoid the normal frame interaction between the site multi-link device and the access point multi-link device The judgment of the end time of the stage is inconsistent, reducing the transmission error between the multi-link device of the site and the multi-link device of the access point, thereby improving the utilization rate of air interface resources.

In a possible implementation manner of the present application, the above termination condition may be determined through negotiation between the access point multi-link device and the station multi-link device.

Fig. 13 is a flow chart showing a frame interaction control method according to an exemplary embodiment. The frame interaction control method may be executed interactively between an access point multi-link device and a station multi-link device, for example, the station The multi-link device may be the terminal device 110 in the implementation environment shown in FIG. 1 , and the access point multi-link device may be the access point device 120 in the implementation environment shown in FIG. 1 . As shown in Fig. 13, the method may include the following steps.

In step 1301, the station multi-link device and the access point multi-link device exchange phase control information; the phase control information is used to negotiate the termination condition of the downlink normal frame interaction phase.

That is to say, in this embodiment of the application, between the site multi-link device and the access point multi-link device, the above-mentioned downlink normal The end condition of the frame interaction phase may also be negotiated in the initial control frame interaction phase for the end condition of the downlink normal frame interaction phase.

In a possible implementation, if the site multi-link device and the access point multi-link device negotiate the above-mentioned downlink normal frame interaction phase during the establishment phase of the enhanced multi-link single radio frequency or enhanced multi-link multi-radio frequency connection end condition, the phase control information includes at least one of a connection establishment request and a connection establishment response corresponding to the connection establishment request;

Wherein, the connection establishment request is sent by the multi-link device of the access point, and is a request for establishing an enhanced multi-link single radio frequency or an enhanced multi-link multi-radio connection.

That is to say, during the establishment of an enhanced multi-link single radio or enhanced multi-link multi-radio connection, the access point multi-link device can send a connection establishment request to the site multi-link device, and the site multi-link device can send a connection establishment request to the access point The peer multilink device returns a connection establishment response. In the embodiment of this application, the station multi-link device and the access point multi-link device can multiplex the above connection establishment request and/or connection establishment response to exchange phase control information, so as to negotiate and determine the end condition of the downlink normal frame interaction phase .

The link device accepts the end condition, and returns a connection establishment response to the access point multi-link device; or, the access point multi-link device sends a connection establishment request to the site multi-link device, if the access point multi-link device If it is determined to establish a multi-link connection, a connection establishment response is returned to the access point multi-link device, and the connection establishment response includes information used to indicate the end condition of the downlink normal frame interaction phase.

In another possible implementation, if the end condition of the downlink normal frame interaction phase is negotiated between the station multi-link device and the access point multi-link device during the initial control frame interaction phase, the control information of this phase includes the initial control frame and at least one of the response frame corresponding to the initial control frame.

That is to say, in this embodiment of the application, the station multi-link device and the access point multi-link device can multiplex the initial control frame in the initial control frame interaction phase and/or the response frame corresponding to the initial control frame to control the interaction phase. information to negotiate and determine the end conditions of the downlink normal frame interaction phase.

For example, the above negotiation process may include: the access point multi-link device may send an initial control frame to the station multi-link device, and the initial control frame includes information for indicating the end condition of the downlink normal frame interaction phase. The link device accepts the end condition, and returns a response frame to the access point multi-link device; or, the access point multi-link device sends an initial control frame to the station multi-link device, and the access point multi-link device sends an initial control frame to the access point multi-link device. The in-point multi-link device returns a response frame, and the response frame includes information for indicating the end condition of the downlink normal frame interaction phase.

For the information contained in the above-mentioned phase control information, reference may be made to the description in the embodiment shown in FIG. 8 , and details are not repeated here.

Step 1302: In the process of the downlink normal frame interaction between the station multi-link device and the access point multi-link device, if the end condition is satisfied, end the downlink normal frame interaction with the access point multi-link device stage.

In step 1303, the access point multi-link device ends the normal downlink frame interaction phase with the station multi-link device when the end condition is satisfied during the process of interacting with the station multi-link device.

Wherein, for the execution process of the above step 1302 and step 1303, reference may be made to the description under step 802 and step 803 in the above embodiment shown in FIG. 8 , which will not be repeated here.

Through the scheme shown in the embodiment of this application, AP MLD and STA MLD can negotiate a switching delay time Switch Delay, and this Switch Delay is calculated from a time point that both AP MLD and STA MLD can identify. When AP MLD and STA MLD During this period, when at least one frame exchange is not successfully completed, the AP MLD and STA MLD consider the Normal Frame exchange Phase to be over.

For example, please refer to FIG. 14 , which shows a schematic diagram of judging the end of the downlink normal frame interaction phase involved in the embodiment of the present application. As shown in Figure 14, the time point jointly recognized by AP MLD and STA MLD can be defined as the end point of the frame transmitted by AP MLD in the last successful frame interaction between AP MLD and STA MLD.

A) The time between the end time point of the frame to be sent and the end time point of the frame transmitted by the AP MLD in the last successful frame interaction (that is, the downlink frame) does not exceed the Switch Delay time.

B) The length of time between the end time point of the expected STA MLD reply confirmation frame of the frame to be sent and the end time point of the frame transmitted by the last successful frame interaction AP MLD does not exceed the Switch Delay time.

Please refer to FIG. 15 , which shows a schematic diagram of multi-link transmission involved in this embodiment of the present application. Taking the AP MLD in the downlink Normal frame exchange, the STA MLD does not correctly receive the DL data of the AP MLD (that is, the downlink frame) as an example, through the scheme shown in the embodiment of this application, when the AP MLD determines that the DL PPDU that needs to be retransmitted When the interaction exceeds the defined Switch Delay, the AP MLD will give up retransmitting the DL PPDU and wait for the end of the Normal Frame Exchange Phase (that is, the time indicated by the Switch Delay).
