Detailed ways

In order to make the purposes, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments It is a part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

After multiple links are established between the AP MLD and the non-AP MLD, when the AP MLD needs to transmit data to the non-AP MLD, which link should be selected to transmit data among all the links, in the current standard Not limited. However, the multiple links between the two MLDs are at different frequencies. In some cases, such as when the distance is long, some links may be in an unsatisfactory signal state. However, for AP MLD, it can only obtain the status of link signals when transmitting data, and cannot know whether each link signal is ideal in real time. In this way, AP MLD may choose a link with an unsatisfactory link signal to transmit data, which affects the transmission efficiency. The following is an example of the scenario where AP MLD transmits data to non-AP MLD.

For example, for a non-AP STA in power saving mode (Power Save Mode, PSM), when there is no data to send, it can enter the sleep (doze) state, and before entering the doze state, pass the power management subfield (Power Management subfield) to notify the AP that the AP will buffer the downlink data for the non-AP STA entering the doze state. The non-AP STA of PSM enters the awake (awake) state from the doze state every other listening period (Listen Interval) to receive the beacon (Beacon) frame, by detecting the traffic indication table element (Traffic Indication Map element, TIM element) in the Beacon frame ) to determine whether there is downlink data to be received, and if so, send a power saving-poll (PS-Poll) frame to the AP, and the AP will then send the cached downlink data to the non-AP STA. In the ML system, the AP can indicate which link transmits the cached data through the Multi-Link Traffic element in the beacon frame on a link, and the AP may indicate the link with an unsatisfactory signal , resulting in untimely data transmission (the indicated link is unreachable) or low efficiency (the indicated link signal is not good).

For example, for a non-AP STA that has signed a target wake-up time TWT (Target Wake Time) agreement with the AP, the non-AP STA will enter the awake state during the agreed TWT service period (TWT service period, TWT SP). If the agreed TWT parameter Trigger is 1, it means that the AP will send a trigger frame (Trigger Frame). In this case, if the non-AP STA has uplink data to send, it needs to wait for the AP’s Trigger Frame to allocate resources, and the AP may TWT SP on the link with unsatisfactory signal will be selected to transmit data.

In order to prevent AP MLD from selecting a link with an unsatisfactory link signal to transmit data, it is considered in the embodiment of this application that for non-AP MLD, it can know whether the link signal is ideal in real time by measuring the Beacon frame of AP MLD, so , the non-AP MLD can send the measured information about whether the link signal is ideal to the AP MLD, so that the AP MLD can obtain the information about whether the link signal is ideal, and based on this, select the link with the ideal link signal To transmit data to ensure data transmission efficiency.

The data transmission method provided by this application will be described in detail below through specific embodiments. It can be understood that the following specific embodiments may be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments.

FIG. 1 is a schematic flowchart of a data transmission method provided by an embodiment of the present application. As shown in Figure 1, the method includes:

S101. The non-AP MLD determines the quality of at least one second link between the non-AP MLD and the AP MLD.

There are multiple links between non-AP MLD and AP MLD, and the second link can be any link in the multiple links. Non-AP MLD can determine one or more second links by measuring Beacon frames For the quality of , the measurement method can refer to related technologies, which are not limited in the embodiments of the present application.

S102. If the quality of the second link meets the third preset condition, the non-AP MLD sends indication information to the AP MLD through the first link.

Wherein, the indication information is used to indicate the quality of the second link.

The indication information may include at least one of the following: signal strength, signal quality, or link state, that is, the quality of the second link may include at least one of the following: signal strength, signal quality, or link state. For example, the signal strength can be characterized by a received channel power parameter (Received Channel Power Indicator, RCPI); the signal quality can be characterized by a received signal-to-noise ratio parameter (Received Signal to Noise Indicator, RSNI); the link state can be a combination of RCPI and/ Or RSNI is converted to the status of good, medium, poor and broken. Optionally, the indication information may be included in a link measurement report frame (Link Measurement Report frame), or the indication information may also be included in other frames that can complete the indication function, which is not limited in this embodiment of the present application.

Optionally, in order to prevent AP MLD from selecting a link with an unsatisfactory link signal, that is, a link with poor quality to transmit data, non-AP MLD needs to indicate the link with poor quality to AP MLD through indication information. Therefore, the second link The quality of the path satisfies the third preset condition, which may be that at least one of signal strength, signal quality, or link status satisfies a condition of poor quality, and an example will be described below.

For example, the quality of the second link meeting the third preset condition may include: the signal strength of the second link is less than a fifth preset value, so that the non-AP MLD sends indication information to the AP MLD through the first link, indicating The information is used to indicate the signal strength of the second link. If the signal strength of the second link is less than the fifth preset value, it means that the signal strength of the second link is weak, that is, the quality of the link is poor, and the link signal is not ideal. The fifth preset value can be set according to the actual situation.

For example, the quality of the second link meeting the third preset condition may include: the change value of the signal strength of the second link within the preset time period is greater than the seventh preset value, so that the non-AP MLD passes the first link The path sends indication information to the AP MLD, where the indication information is used to indicate the signal strength of the second link. The change value of the signal strength of the second link within the preset time period is greater than the seventh preset value, indicating that the signal strength of the second link fluctuates greatly, and at this time, the quality of the link may become poor, that is, If the link signal is not ideal, the seventh preset value can be set according to the actual situation.

For example, the quality of the second link meeting the third preset condition may include: the signal quality of the second link is less than the eighth preset value, so that the non-AP MLD sends indication information to the AP MLD through the first link, indicating The information is used to indicate the signal quality of the second link. If the signal quality of the second link is lower than the eighth preset value, it means that the signal quality of the second link is poor, that is, the link quality is poor, and the link signal is not ideal. The eighth preset value can be set according to the actual situation.

For example, the quality of the second link meeting the third preset condition may include: the change value of the signal quality of the second link within a preset time period is greater than the tenth preset value, so that the non-AP MLD passes the first link The path sends indication information to the AP MLD, where the indication information is used to indicate the signal quality of the second link. The change value of the signal quality of the second link within the preset time period is greater than the tenth preset value, which means that the signal quality of the second link fluctuates greatly. If the channel signal is not ideal, the tenth preset value can be set according to the actual situation.

For example, the quality of the second link meeting the third preset condition may include: the link status of the second link is poor or disconnected, so that the non-AP MLD sends indication information to the AP MLD through the first link, The indication information is used to indicate the link state of the second link. It should be noted that the link state of the second link includes several levels that can be set according to needs, and the four states of good, medium, bad, and broken in the embodiment of this application are only for illustration, rather than limiting the link The state includes only these 4 states.

The first link may be the same as or different from the second link. For example, the non-AP MLD determines that the quality of a second link is poor, and then selects another first link with better quality to send the indication information. For example, non-AP MLD determines that the quality of all links is poor, that is, at least one second link is all links, and non-AP MLD can select a link with relatively good quality among all links as the first link The route sends indication information to the AP MLD.

Optionally, in addition to indicating the link with poor quality to the AP MLD through the indication information, the non-AP MLD can also indicate to the AP MLD again when the link quality is restored, that is, the quality of the second link Satisfying the third preset condition may also mean that at least one of signal strength, signal quality, or link state satisfies a condition of better quality, and an example will be described below.

For example, the quality of the second link meeting the third preset condition may include: the signal strength of the second link is greater than a sixth preset value, and the sixth preset value is greater than a fifth preset value, so that the non-AP MLD passes The first link sends indication information to the AP MLD, where the indication information is used to indicate the signal strength of the second link. If the signal strength of the second link is greater than the sixth preset value, it means that the signal strength of the second link is stronger, that is, the quality of the link is better, and the link signal is ideal. The sixth preset value can be set according to the actual situation.

For example, the quality of the second link meeting the third preset condition may include: the change value of the signal strength of the second link within the preset time period is greater than the seventh preset value, so that the non-AP MLD passes the first link The path sends indication information to the AP MLD, where the indication information is used to indicate the signal strength of the second link. The change value of the signal strength of the second link within the preset time period is greater than the seventh preset value, indicating that the signal strength of the second link fluctuates greatly. At this time, the quality of the link may become better, that is, Link signal is ideal.

For example, the quality of the second link meeting the third preset condition may include: the signal quality of the second link is greater than the ninth preset value, and the ninth preset value is greater than the eighth preset value, so that the non-AP MLD passes The first link sends indication information to the AP MLD, where the indication information is used to indicate the signal quality of the second link. If the signal quality of the second link is greater than the ninth preset value, it means that the signal quality of the second link is better, that is, the link quality is better, and the link signal is ideal. The ninth preset value can be set according to the actual situation.

For example, the quality of the second link meeting the third preset condition may include: the change value of the signal quality of the second link within a preset time period is greater than the tenth preset value, so that the non-AP MLD passes the first link The path sends indication information to the AP MLD, where the indication information is used to indicate the signal quality of the second link. The change value of the signal quality of the second link within the preset time period is greater than the tenth preset value, which means that the signal quality of the second link fluctuates greatly. The road signal is not ideal.

For example, the quality of the second link meeting the third preset condition may include: the link state of the second link is a good or medium state, so that the non-AP MLD sends indication information to the AP MLD through the first link, The indication information is used to indicate the link state of the second link.

The first link may be the same as or different from the second link. For example, the non-AP MLD determines that the quality recovery of a second link is better, and then selects the second link as the first link to send the indication information. For example, the non-AP MLD determines that the quality recovery of all links is better, that is, at least one second link is all links, and the non-AP MLD can select any link in all links as the first link to communicate with the AP. The MLD sends indication information.

In addition, it should be noted that the quality of the second link meeting the third preset condition may include one item or multiple items in the foregoing examples.

S103. If the indication information satisfies the first preset condition, the AP MLD uses the multiple links between the AP MLD and the non-AP MLD, and the target link except the second link transmits data to the non-AP MLD .

Wherein, the quality of the target link is higher than the quality of the second link.

After the AP MLD receives the indication information sent by the non-AP MLD through the first link, it can determine the quality of the second link according to the indication information, and select the link for transmitting data according to the quality of the second link. If the indication information satisfies the first preset condition, that is, when the quality of the second link is poor, the AP MLD selects a target link whose quality is higher than that of the second link to transmit data, thereby ensuring transmission efficiency.

Exemplarily, the indication information that satisfies the first preset condition includes: the signal strength of the second link is smaller than the first preset value. The first preset value and the fifth preset value may be the same or different, and the signal strength of the second link being less than the first preset value indicates that the signal strength of the second link is weak, that is, the quality of the link is poor, and the link The signal is not ideal, therefore, the AP MLD can select a higher-quality target link other than the second link to transmit data, and the first preset value can be set according to the actual situation.

Exemplarily, the indication information that satisfies the first preset condition includes: the signal quality of the second link is smaller than a second preset value. The second preset value and the eighth preset value can be the same or different, and the signal quality of the second link is less than the second preset value, indicating that the signal quality of the second link is better, that is, the quality of the link is poor, and the signal quality of the second link is lower than the second preset value. The signal is not ideal, therefore, the AP MLD can select a higher-quality target link other than the second link to transmit data, and the second preset value can be set according to the actual situation.

For example, if the link status of the second link is poor or disconnected, the non-AP MLD sends indication information to the AP MLD through the first link, and the indication information is used to indicate the link status of the second link.

S104. If the indication information satisfies the second preset condition, the AP MLD determines the target link in at least one link including the second link, and transmits data to the non-AP MLD through the target link.

After the AP MLD receives the indication information sent by the non-AP MLD through the first link, it can determine the quality of the second link according to the indication information, and select the link for transmitting data according to the quality of the second link. If the indication information satisfies the second preset condition, that is, when the quality of the second link is better, the AP MLD may use the second link as a candidate link for selecting the target link, thereby ensuring transmission efficiency.

Exemplarily, the indication information satisfies the second preset condition, including: the signal strength of the second link is greater than a third preset value. The first preset value and the fifth preset value may be the same or different, and the signal strength of the second link being less than the first preset value indicates that the signal strength of the second link is weak, that is, the quality of the link is poor, and the link The signal is not ideal. Therefore, when the AP MLD determines the target link for transmitting data, the second link can be used as a candidate link, that is, the AP MLD determines the target link in at least one link including the second link. The third preset value can be set according to actual conditions.

Exemplarily, the indication that the information satisfies the second preset condition includes: the signal quality of the second link is greater than a fourth preset value. The fourth preset value and the ninth preset value may be the same or different, and the signal quality of the second link greater than the fourth preset value indicates that the signal quality of the second link is better, that is, the quality of the link is better, and the link The signal is ideal. Therefore, when the AP MLD determines the target link for transmitting data, it can use the second link as a candidate link, that is, the AP MLD determines the target link in at least one link including the second link. The fourth preset value can be set according to actual conditions.

For example, the indication information satisfies the second preset condition, including: the link state of the second link is good or in the state, which means that the quality of the second link is better, the link signal is ideal, and the AP MLD is determining the transmission When the data is a target link, the second link may be used as a candidate link, that is, the AP MLD determines the target link in at least one link including the second link.

In the data transmission method provided by the embodiment of the present application, the quality of the link is determined by the non-AP MLD, and the quality of the link is sent to the AP MLD through the indication information, so that the AP MLD can select an ideal link signal based on this. link to transmit data to ensure data transmission efficiency.

It should be noted that the quality of the second link involved in the above-mentioned embodiments includes preset values in the conditions satisfied, such as the first preset value, the second preset value... up to the tenth preset value, and each preset The values can be set separately for each second link. For example, the preset values corresponding to different frequency bands (bands) can be different. For example, the first preset value corresponding to the 5G link is the same as that corresponding to the 2.4G link. The first preset value may be different, and the second preset value corresponding to the 5G link may also be different from the second preset value corresponding to the 2.4G link.
