Detailed Description
In order to make the objects, 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 with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application without making any creative effort belong to the protection scope of the present application.
After a plurality of links are established between the AP MLD and the non-AP MLD, when the AP MLD has data to transmit to the non-AP MLD, which link is specifically selected from all the links to transmit the data is not limited in the current standard. However, the multiple links between the two MLDs are at different frequencies, and in some cases, such as when the distance is long, part of the links may be in a state where the signal is not ideal. However, for the AP MLD, the state of the link signal can only be acquired when data is transmitted, and it is not possible to know whether each link signal is ideal in real time. Thus, the AP MLD may select a link with an imperfect link signal to transmit data, which affects transmission efficiency, and a scenario in which the AP MLD transmits data to the non-AP MLD is described below as an example.
For example, for a non-AP STA in Power Save Mode (PSM), when there is no data to be transmitted, the STA may enter a sleep (doze) state, and notify the AP through a Power Management subfield (Power Management subfield) of the MAC frame before entering the doze state, where the AP may buffer downlink data for the non-AP STA entering the doze state. A non-AP STA of the PSM enters an awake (awake) state from a doze state every other monitoring period (Listen Interval) to receive a Beacon (Beacon) frame, determines whether downlink data are to be received or not by detecting a Traffic Indication Map element (TIM element) in the Beacon frame, and sends a power saving-polling (PS-Poll) frame to the AP if the downlink data are to be received, and the AP then sends the buffered downlink data to the non-AP STA. In ML systems, an AP may indicate which Link to transmit buffered data over a Link via a Multi-Link Traffic element (Multi-Link Traffic element) in a beacon frame on the Link, and the AP may indicate a Link whose signal is not ideal, resulting in untimely (indicated Link not on) or inefficient data transmission (indicated Link not signaled).
For example, for a non-AP STA that signs a Target Wake Time (TWT) agreement with an AP, the non-AP STA may enter an awake state for an agreed TWT service period (TWT SP). If the agreed Trigger parameter Trigger is 1, it indicates 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 Trigger Frame of the AP to allocate resources, and the AP may select a TWT SP on a link whose signal is not ideal to transmit data.
In order to avoid that the AP MLD selects a link with an unsatisfactory link signal to transmit data, in the embodiment of the present application, it is considered that, for the non-AP MLD, it can know whether the link signal is satisfactory or not in real time by measuring the Beacon frame of the AP MLD, and therefore, the non-AP MLD can send the information of whether the link signal measured by the non-AP MLD is satisfactory or not to the AP MLD, so that the AP MLD can obtain the information of whether the link signal is satisfactory or not, and select the link with the satisfactory link signal to transmit data based on the information, thereby ensuring the data transmission efficiency.
The data transmission method provided by the present application will be described in detail below by specific examples. It is to be understood that the following detailed description may be combined with other embodiments, and that 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 according to an embodiment of the present application. As shown in fig. 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 the non-AP MLD and the AP MLD, the second link may be any one of the multiple links, the non-AP MLD may determine the quality of one or more second links by measuring the Beacon frame, and the measurement method may refer to the related art, which is not limited in this embodiment of the application.
And S102, if the quality of the second link meets a third preset condition, the non-AP MLD sends indication information to the AP MLD through the first link.
Wherein the indication information is used for indicating the quality of the second link.
The indication information may include at least one of: signal strength, signal quality or link status, i.e. the quality of the second link may comprise at least one of: signal strength, signal quality, or link status. For example, the signal strength may be characterized by a Received Channel Power Indicator (RCPI); the Signal quality can be characterized by a Received Signal to Noise Indicator (RSNI); the link state may be a state that transitions RCPI and/or RSNI to good, medium, bad, or 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 avoid the AP MLD selecting a link with a non-ideal link signal, that is, a link with poor quality, to transmit data, the non-AP MLD needs to indicate the link with poor quality to the AP MLD through the indication information, so that the quality of the second link satisfies a third preset condition, that may be at least one of signal strength, signal quality, or link status satisfies the condition of poor quality, which is described in the following.
For example, the quality of the second link satisfying the third preset condition may include: and the signal strength of the second link is smaller than a fifth preset value, so that the non-AP MLD sends indication information to the AP MLD through the first link, and the indication information is used for indicating the signal strength of the second link. The fact that the signal strength of the second link is smaller than the fifth preset value indicates that the signal strength of the second link is weak, namely the quality of the link is poor, the link signal is not ideal, and the fifth preset value can be set according to actual conditions.
For example, the quality of the second link satisfying the third preset condition may include: and the change value of the signal strength of the second link in the preset time period is greater than a seventh preset value, so that the non-AP MLD sends indication information to the AP MLD through the first link, and the indication information is used for indicating the signal strength of the second link. The variation value of the signal strength of the second link in the preset time period is greater than the seventh preset value, which indicates that the fluctuation of the signal strength of the second link is large, and at this time, the quality of the link may become poor, that is, the link signal is not ideal, and the seventh preset value may be set according to actual conditions.
For example, the quality of the second link satisfying the third preset condition may include: and the signal quality of the second link is less than an eighth preset value, so that the non-AP MLD sends indication information to the AP MLD through the first link, wherein the indication information is used for indicating the signal quality of the second link. The fact that the signal quality of the second link is smaller than the eighth preset value indicates that the signal quality of the second link is poor, namely the quality of the link is poor, the link signal is not ideal, and the eighth preset value can be set according to actual conditions.
For example, the quality of the second link satisfying the third preset condition may include: and the change value of the signal quality of the second link in the preset time period is greater than a tenth preset value, so that the non-AP MLD sends indication information to the AP MLD through the first link, and the indication information is used for indicating the signal quality of the second link. The variation value of the signal quality of the second link in the preset time period is greater than the tenth preset value, which indicates that the fluctuation of the signal quality of the second link is large, and at this time, the quality of the link may become poor, and the link signal is not ideal, and the tenth preset value may be set according to actual conditions.
For example, the quality of the second link satisfying the third preset condition may include: and the link state of the second link is a poor or broken state, so that the non-AP MLD sends indication information to the AP MLD through the first link, wherein the indication information is used for indicating the link state of the second link. It should be noted that the link status of the second link includes several levels, which may be set according to needs, and the 4 states of good, medium, bad, and broken in the embodiment of the present application are only used for illustration, and the link status is not limited to include only these 4 states.
The first link may be the same as or different from the second link, for example, the non-AP MLD may select another first link with better quality to send the indication information if it determines that one second link is of worse quality. For example, the non-AP MLD determines that the quality of all links is poor, that is, at least one second link is all links, and the non-AP MLD may select one of all links with relatively good quality as the first link to send the indication information to the AP MLD.
Optionally, the non-AP MLD may indicate, through the indication information, the link with poor quality to the AP MLD, and may also indicate, when the link quality is recovered, to the AP MLD again, that is, the quality of the second link satisfies a third preset condition, or at least one of the signal strength, the signal quality, and the link state satisfies a condition with good quality, which is described in the following by way of example.
For example, the quality of the second link satisfying the third preset condition may include: and 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 sends indication information to the AP MLD through the first link, and the indication information is used for indicating the signal strength of the second link. The fact that the signal strength of the second link is greater than the sixth preset value indicates that the signal strength of the second link is strong, namely the quality of the link is good, the link signal is ideal, and the sixth preset value can be set according to actual conditions.
For example, the quality of the second link satisfying the third preset condition may include: and the change value of the signal strength of the second link in the preset time period is greater than a seventh preset value, so that the non-AP MLD sends indication information to the AP MLD through the first link, and the indication information is used for indicating the signal strength of the second link. The variation value of the signal strength of the second link in the preset time period is greater than the seventh preset value, which indicates that the fluctuation of the signal strength of the second link is large, and at this time, it may be that the quality of the link becomes better, that is, the link signal is ideal.
For example, the quality of the second link satisfying the third preset condition may include: and the signal quality of the second link is greater than a ninth preset value, and the ninth preset value is greater than an eighth preset value, so that the non-AP MLD sends indication information to the AP MLD through the first link, and the indication information is used for indicating the signal quality of the second link. The fact that the signal quality of the second link is greater than the ninth preset value indicates that the signal quality of the second link is good, namely the quality of the link is good, the link signal is ideal, and the ninth preset value can be set according to actual conditions.
For example, the quality of the second link satisfying the third preset condition may include: and the change value of the signal quality of the second link in the preset time period is greater than a tenth preset value, so that the non-AP MLD sends indication information to the AP MLD through the first link, and the indication information is used for indicating the signal quality of the second link. The variation value of the signal quality of the second link in the preset time period is greater than the tenth preset value, which indicates that the fluctuation of the signal quality of the second link is large, and at this time, the quality of the link may become better, and the link signal is not ideal.
For example, the quality of the second link satisfying 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 being used for indicating the link state of the second link.
The first link may be the same as or different from the second link, for example, if the non-AP MLD determines that a second link is better recovered in quality, the second link is selected as the first link to send the indication information. For example, the non-AP MLD determines that the quality of all links is better recovered, that is, at least one second link is all links, and the non-AP MLD may select any one of all links as the first link to send the indication information to the AP MLD.
It should be further noted that the quality of the second link meeting the third preset condition may include one or more of the above examples.
S103, if the indication information meets the first preset condition, the AP MLD adopts a plurality of links between the AP MLD and the non-AP MLD, and the target links except the second link transmit data to the non-AP MLD.
Wherein the quality of the target link is higher than the quality of the second link.
After receiving the indication information sent by the non-AP MLD through the first link, the AP MLD may determine the quality of the second link according to the indication information, and select a link for transmitting data according to the quality of the second link. If the indication information meets the first preset condition, namely the quality of the second link is poor, the AP MLD selects a target link with the quality higher than that of the second link to transmit data, and therefore transmission efficiency is guaranteed.
For example, the indication information satisfies a first preset condition, including: the signal strength of the second link is smaller than a first preset value. The first preset value and the fifth preset value may be the same or different, and the fact that the signal strength of the second link is smaller than the first preset value indicates that the signal strength of the second link is weaker, that is, the quality of the link is poorer, and the link signal is not ideal, so the AP MLD may select a target link with higher quality other than the second link to transmit data, and the first preset value may be set according to an actual situation.
For example, the indication information satisfies a first preset condition, including: the signal quality of the second link is less than a second preset value. The second preset value and the eighth preset value may be the same or different, and the fact that the signal quality of the second link is smaller than the second preset value indicates that the signal quality of the second link is better, that is, the quality of the link is poorer, and the link signal is not ideal, so the AP MLD may select a target link with higher quality other than the second link to transmit data, and the second preset value may be set according to actual conditions.
For example, if the link status of the second link is a bad or broken status, the non-AP MLD sends indication information to the AP MLD through the first link, where the indication information is used for indicating the link status of the second link.
And S104, if the indication information meets a second preset condition, determining a target link in at least one link comprising a second link by the AP MLD, and transmitting data to the non-AP MLD through the target link.
After receiving the indication information sent by the non-AP MLD through the first link, the AP MLD may determine the quality of the second link according to the indication information, and select a link for transmitting data according to the quality of the second link. If the indication information meets the second preset condition, that is, the quality of the second link is good, the AP MLD may use the second link as a candidate link of its selection target link, thereby ensuring transmission efficiency.
For example, the indication information satisfies a 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 a value that the signal strength of the second link is smaller 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 signal is not ideal, so that the AP MLD may use the second link as a candidate link when determining the target link for transmitting data, 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.
For example, the indication information satisfies a second preset condition, including: and 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 a value that the signal quality of the second link is 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 signal is ideal, so that the AP MLD may use the second link as a candidate link when determining a target link for transmitting data, 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 a second preset condition, including: the link state of the second link is a good or medium state, which indicates that the quality of the second link is good and the link signal is ideal, and the AP MLD may use the second link as a candidate link when determining a target link for transmitting data, 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 application, the quality of the link is determined through 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 of a link signal to transmit data based on the quality of the link signal, and the data transmission efficiency is ensured.
It should be noted that, in the above embodiments, the preset values, for example, the first preset value, the second preset value \ 823030, in the conditions that the quality of the second link meets, until the tenth preset value, may be respectively set according to each second link, for example, the preset values corresponding to different frequency bands (bands) may be different, for example, the first preset value corresponding to the 5G link may be different from the first preset value corresponding to the 2.4G link, and the second preset value corresponding to the 5G link may be different from the second preset value corresponding to the 2.4G link.
