Description

Technical Field

[0001] This application relates to communication technology, and more particularly to a data transmission method, apparatus, chip, chip module, and electronic device. Background Technology

[0002] The IEEE 802.11be standard introduced multi-link (ML) technology. A multi-link device (MLD) can contain multiple stations (STAs), allowing multiple links to be established between two MLDs. Correspondingly, data can be transmitted over multiple links. The links used for data transmission are determined by the mapping relationship between traffic identifiers (TrafficID, TID) and links; by default, TIDs are mapped to all links.

[0003] After multiple links are established between an Access Point (AP) MLD and a non-AP MLD, the current standard does not specify which link to select from all the links mapped by the TID for data transmission when the AP MLD needs to transmit data to the non-AP MLD. However, some links between these two MLDs may have poor signal strength, and the AP MLD may choose a link with poor signal strength to transmit data, affecting transmission efficiency.

[0062] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] After multiple links are established between the AP MLD and the non-AP MLD, the current standard does not specify which link to select for data transmission when the AP MLD needs to transmit data to the non-AP MLD. However, since the multiple links between the two MLDs operate at different frequencies, in some cases, such as over long distances, some links may experience suboptimal signal strength. The AP MLD can only obtain the link signal status during data transmission and cannot monitor the signal strength of each link in real time. Therefore, the AP MLD may select a link with suboptimal signal strength to transmit data, affecting transmission efficiency. The following example illustrates a scenario where the AP MLD transmits data to the non-AP MLD.

[0064] For example, for a non-AP STA in Power Save Mode (PSM), when there is no data to send, it can enter a doze state. Before entering the doze state, it notifies the AP via the Power Management subfield of the MAC frame. The AP will then cache downlink data for the non-AP STA in the doze state. Every listen interval, the PSM non-AP STA transitions from the doze state to the awake state to receive beacon frames. By checking the Traffic Indication Map element (TIM element) in the beacon frame, it determines whether there is downlink data to be received. If so, it sends a Power Save Polling (PS-Poll) frame to the AP, which then sends the cached downlink data to the non-AP STA. In an ML system, an AP can indicate which link to transmit buffered data through the multi-link traffic element in a beacon frame on a link. However, the AP may indicate a link with poor signal, resulting in untimely data transmission (the indicated link is down) or inefficiency (the indicated link has a poor signal).

[0065] For example, for a non-APSTA that has signed a Target Wake Time (TWT) agreement with the AP, the non-AP STA will enter the awake state during the agreed TWT service period (TWT SP). If the agreed TWT parameter Trigger is 1, it means that the AP will send a 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 choose a TWT SP on a link with poor signal strength to transmit data.

[0066] To prevent the AP MLD from selecting a link with an unsatisfactory signal for data transmission, this embodiment considers that the non-AP MLD can measure the Beacon frames of the AP MLD in real time to determine whether the link signal is ideal. Therefore, the non-AP MLD can send the measured link signal information to the AP MLD, so that the AP MLD can obtain the link signal information and select a link with an ideal signal for data transmission, thus ensuring data transmission efficiency.

[0067] The data transmission method provided in this application will be described in detail below through specific embodiments. It is understood that the following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be described again in some embodiments.

[0068] Figure 1 This is a flowchart illustrating a data transmission method provided in an embodiment of this application. Figure 1 As shown, the method includes:

[0069] S101, non-AP MLD determines the quality of at least one second link between the non-AP MLD and the AP MLD.

[0070] There are multiple links between the non-AP MLD and the AP MLD. The second link can be any of these multiple links. The non-AP MLD can determine the quality of one or more second links by measuring Beacon frames. The measurement method can refer to relevant technologies, but is not limited in this embodiment.

[0071] S102. If the quality of the second link meets the third preset condition, the non-AP MLD sends an indication message to the APMLD through the first link.

[0072] The indication information is used to indicate the quality of the second link.

[0073] The indication information may include at least one of the following: signal strength, signal quality, or link status. That is, the quality of the second link may include at least one of the following: signal strength, signal quality, or link status. For example, signal strength may be characterized by the Received Channel Power Indicator (RCPI); signal quality may be characterized by the Received Signal to Noise Indicator (RSNI); and link status may be a state that converts RCPI and / or RSNI to good, neutral, poor, or disconnected. Optionally, the indication information may be included in a link measurement report frame, or the indication information may also be included in other frames that can perform the indication function. This application embodiment does not limit this.

[0074] Optionally, to prevent the AP MLD from selecting a link with poor signal quality to transmit data, the non-AP MLD needs to indicate the link with poor quality to the AP MLD through indication information. Therefore, the quality of the second link meets the third preset condition, which can be at least one of signal strength, signal quality, or link status that meets the condition of poor quality. The following is an example.

[0075] 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, thereby the non-AP MLD sends an indication message to the AP MLD through the first link. The indication message is used to indicate the signal strength of the second link. The signal strength of the second link being less than the fifth preset value indicates that the signal strength of the second link is weak, that is, the link quality is poor and the link signal is not ideal. The fifth preset value can be set according to the actual situation.

[0076] For example, the quality of the second link meeting the third preset condition may include: the change in the signal strength of the second link within a preset time period is greater than a seventh preset value. Therefore, the non-AP MLD sends an indication message to the AP MLD through the first link, indicating the signal strength of the second link. A change in the signal strength of the second link within a preset time period greater than the seventh preset value indicates a large fluctuation in the signal strength of the second link, which may indicate a deterioration in link quality, i.e., an unsatisfactory link signal. The seventh preset value can be set according to the actual situation.

[0077] 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 an eighth preset value, thereby the non-AP MLD sends an indication message to the AP MLD through the first link. The indication message is used to indicate the signal quality of the second link. The signal quality of the second link being less than the eighth preset value indicates 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.

[0078] For example, the quality of the second link meeting the third preset condition may include: the change in the signal quality of the second link within a preset time period is greater than a tenth preset value. Therefore, the non-AP MLD sends an indication message to the AP MLD through the first link. This indication message is used to indicate the signal quality of the second link. The fact that the change in the signal quality of the second link within the preset time period is greater than the tenth preset value indicates that the signal quality of the second link fluctuates significantly. This may indicate that the link quality has deteriorated and the link signal is not ideal. The tenth preset value can be set according to the actual situation.

[0079] For example, the quality of the second link meeting the third preset condition may include: the link status of the second link being poor or disconnected, thereby the non-AP MLD sending indication information to the AP MLD through the first link. The indication information is used to indicate the link status of the second link. It should be noted that the link status of the second link includes several levels that can be set as needed. The four states of good, medium, poor, and disconnected in this embodiment are only used for illustrative purposes and are not intended to limit the link status to only these four states.

[0080] The first link can be the same as or different from the second link. For example, if a non-AP MLD determines that one of the second links has poor quality, it will select another first link with better quality to send the indication information. For example, if a non-AP MLD determines that all links have poor quality, meaning that at least one second link is among all links, the non-AP MLD can select the link with relatively better quality among all links as the first link to send the indication information to the AP MLD.

[0081] Optionally, in addition to indicating the link with poor quality to the AP MLD through 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 meets the third preset condition, or at least one of the signal strength, signal quality, or link status meets the condition of better quality. The following is an example.

[0082] For example, the quality of the second link meeting the third preset condition may include: the signal strength of the second link being greater than a sixth preset value, and the sixth preset value being greater than a fifth preset value. Therefore, the non-AP MLD sends an indication message to the AP MLD through the first link. This indication message indicates the signal strength of the second link. A signal strength greater than the sixth preset value indicates a strong signal, meaning the link quality is good and the link signal is ideal. The sixth preset value can be set according to actual conditions.

[0083] For example, the quality of the second link meeting the third preset condition may include: the change in the signal strength of the second link within a preset time period is greater than a seventh preset value, thereby the non-AP MLD sends an indication message to the AP MLD through the first link. The indication message is used to indicate the signal strength of the second link. The change in the signal strength of the second link within the preset time period being greater than the seventh preset value indicates that the signal strength of the second link fluctuates significantly, which may indicate that the link quality has improved, i.e., the link signal is ideal.

[0084] For example, the quality of the second link meeting the third preset condition may include: the signal quality of the second link being greater than the ninth preset value, and the ninth preset value being greater than the eighth preset value. Therefore, the non-AP MLD sends an indication message to the AP MLD through the first link. This indication message is used to indicate the signal quality of the second link. A signal quality of the second link greater than the ninth preset value indicates that the signal quality of the second link is good, that is, the link quality is good and the link signal is ideal. The ninth preset value can be set according to actual conditions.

[0085] For example, the quality of the second link meeting the third preset condition may include: the change in the signal quality of the second link within a preset time period is greater than a tenth preset value, thereby the non-AP MLD sends an indication message to the AP MLD through the first link. This indication message is used to indicate the signal quality of the second link. The change in the signal quality of the second link within the preset time period being greater than the tenth preset value indicates that the signal quality of the second link fluctuates significantly, which may mean that the link quality has improved, but the link signal is not ideal.

[0086] For example, the quality of the second link meeting the third preset condition may include: the link status of the second link being good or neutral, so that the non-AP MLD sends indication information to the AP MLD through the first link, the indication information being used to indicate the link status of the second link.

[0087] The first link can be the same as or different from the second link. For example, if the non-AP MLD determines that a second link has good quality recovery, it will select that second link as the first link to send the indication information. For example, if the non-AP MLD determines that all links have good quality recovery, that is, at least one second link is among all links, the non-AP MLD can choose any link from all links as the first link to send the indication information to the AP MLD.

[0088] It should also be noted that the quality of the second link meeting the third preset condition may include one or more of the conditions mentioned in the above examples.

[0089] S103. If the indication information meets the first preset condition, the AP MLD uses the target link other than the second link among the multiple links between the AP MLD and the non-AP MLD to transmit data to the non-AP MLD.

[0090] The quality of the target link is higher than that of the second link.

[0091] After receiving the indication information sent by the non-AP MLD through the first link, the AP MLD can determine the quality of the second link based on the indication information and select a link for data transmission based on the quality of the second link. If the indication information meets a first preset condition, i.e., the quality of the second link is poor, the AP MLD selects a target link with higher quality than the second link to transmit data, thereby ensuring transmission efficiency.

[0092] For example, the indication information meets the first preset condition, including: the signal strength of the second link is less than the first preset value. The first preset value and the fifth preset value can be the same or different. 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 link quality is poor and the link signal is not ideal. Therefore, the AP MLD can select a target link with higher quality other than the second link to transmit data. The first preset value can be set according to the actual situation.

[0093] For example, the indication information meets the first preset condition, including: the signal quality of the second link is less than the second preset value. The second preset value and the eighth preset value can be the same or different. The signal quality of the second link being less than the second preset value indicates that the signal quality of the second link is good, that is, the link quality is poor and the link signal is not ideal. Therefore, the AP MLD can select a target link with higher quality other than the second link to transmit data. The second preset value can be set according to the actual situation.

[0094] For example, if the link status of the second link is poor or broken, the non-AP MLD sends an indication message to the AP MLD through the first link. The indication message is used to indicate the link status of the second link.

[0095] S104. If the indication information meets 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.

[0096] After receiving the indication information sent by the non-AP MLD through the first link, the AP MLD can determine the quality of the second link based on the indication information and select the link for data transmission based on 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 can use the second link as a candidate link for its target link selection, thereby ensuring transmission efficiency.

[0097] For example, the indication information meets the second preset condition, including: the signal strength of the second link is greater than the third preset value. The first preset value and the fifth preset value can be the same or different. 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 link quality is poor and the link signal is not ideal. Therefore, when determining the target link for data transmission, the AP MLD can consider the second link as a candidate link. That is, the AP MLD determines the target link from at least one link including the second link. The third preset value can be set according to the actual situation.

[0098] For example, the indication information meets the second preset condition, including: the signal quality of the second link is greater than the fourth preset value. The fourth preset value and the ninth preset value can be the same or different. The signal quality of the second link being greater than the fourth preset value indicates that the signal quality of the second link is good, that is, the link quality is good and the link signal is ideal. Therefore, when determining the target link for data transmission, the AP MLD can consider the second link as a candidate link. That is, the AP MLD determines the target link from at least one link that includes the second link. The fourth preset value can be set according to the actual situation.

[0099] For example, if the indication information meets the second preset condition, including: the link status of the second link is good or medium, it means that the quality of the second link is good and the link signal is ideal. When determining the target link for data transmission, the AP MLD can use the second link as a candidate link. That is, the AP MLD determines the target link from at least one link that includes the second link.

[0100] In the data transmission method provided in this application embodiment, the link quality is determined by the non-AP MLD, and the link quality is sent to the AP MLD through indication information. Thus, the AP MLD can select a link with ideal link signal to transmit data based on this, ensuring data transmission efficiency.

[0101] It should be noted that the preset values ​​in the conditions for the quality of the second link involved in the above embodiments, such as the first preset value, the second preset value, ... up to the tenth preset value, can all be set separately for each second link. For example, the preset values ​​corresponding to different frequency bands can be different. For instance, the first preset value corresponding to the 5G link can be different from the first preset value corresponding to the 2.4G link, and the second preset value corresponding to the 5G link can also be different from the second preset value corresponding to the 2.4G link.
