The embodiments of the present disclosure provide a sleep cycle negotiation method, an electronic device, and a storage medium, so as to provide a mechanism for supporting AP (Access Point, AP) power saving.

Among them, the method and the device are based on the same application concept. Since the method and the device solve the problem in a similar principle, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

As a first example, refer to Figure 1, which shows an example of an application scenario of the sleep cycle negotiation method provided by each embodiment of the present disclosure. Among them, the first AP obtains the R-TWT SP of the neighboring AP, and the acquisition method includes step 1-1 or step 1-2.

In the disclosed embodiment, the neighbor AP is, for example, an AP that is relatively close to the first AP in logical topology, for example, the first AP receives a higher signal strength from the neighbor AP, or an AP that is physically close to the first AP, or an AP that is in the same basic service set (BSS) as the first AP; in a WLAN, an AP can obtain a basic service set identifier (BSSID) sent by other APs through channel detection and then discover neighbor APs. Among them, the neighbor AP can be recommended to the STA as a better roaming target; in addition, considering the neighbor AP when adjusting the radio frequency parameters can make full use of spectrum resources and can achieve load balancing among multiple APs.

Step 1-1: The neighbor AP of the first AP broadcasts its own R-TWT SP (R-TWT stands for Restricted Target Wake Time, SP stands for Service Period, R-TWT SP, Restricted Target Wake Time Service Period, restricting the service time of the target wake-up time) information;

or

Step 1-2: The neighbor AP sends the R-TWT SP information to the second AP, instructing the second AP to share the R-TWT SP information with the first AP.

In the embodiments of the present disclosure, unless otherwise specified, a neighbor AP refers to a neighbor AP of a first AP; in the case of special specifications, for example, if the neighbor AP is called AP-1, the second AP may be any other AP among the neighbor APs of AP-1 except the first AP.

Optionally, the embodiment of the present disclosure does not limit the execution order of 1-1 and 1-2.

Step 2: The first AP obtains the R-TWT SP of the neighbor AP through any of the above methods. information, and determine the method for obtaining the R-TWT SP information.

Step 3: The first AP plans a sleep cycle of the first AP under at least one connection according to the method of obtaining the R-TWT SP information. Specifically:

Step 3-1: When the first AP determines that the R-TWT SP information is obtained from the broadcast of the neighbor AP and the R-TWT SP information is applied to the broadcast connection that broadcasts the R-TWT SP information, the first AP plans the sleep period of the first AP under the broadcast connection to overlap with the time indicated by the R-TWT SP information. Specifically, when the R-TWT SP information is applied to the above-mentioned broadcast connection, that is, within the time indicated by the R-TWT SP information, the neighbor AP can transmit low-latency service data under the broadcast connection.

During the time indicated by the R-TWT SP information, the sleep period of the first AP under the broadcast connection is planned to overlap with the time indicated by the R-TWT SP information, that is, the first AP sleeps within the R-TWT SP and under the broadcast connection, thereby avoiding interference with the business data transmission of the neighboring AP under the broadcast connection due to the communication of the first AP during the time indicated by the R-TWT SP information.

It can be understood that in the embodiment of the present disclosure, the sleep period of the first AP under the broadcast connection overlaps with the time indicated by the R-TWT SP information, which may include the situation where the sleep period partially overlaps or completely overlaps with the R-TWT SP time; the embodiment of the present disclosure is not limited to this.

Step 3-2: When the first AP determines that the R-TWT SP information is obtained from the broadcast of a neighboring AP, and the range of connections to which the R-TWT SP information is applied includes: multiple connections, and the service transmitted by the broadcast connection is a low-latency service, the sleep periods of the first AP under the multiple connections are planned to overlap with the time indicated by the R-TWT SP information.

Similarly, within the time indicated by the R-TWT SP information, the sleep period of the first AP under the broadcast connection is planned to overlap with the time indicated by the R-TWT SP information, that is, the first AP sleeps within the R-TWT SP and under the broadcast connection, thereby avoiding interference with the service data transmission of the neighboring AP under the broadcast connection due to the communication of the first AP within the time indicated by the R-TWT SP information, ensuring the transmission of low-latency service data and avoiding transmission delays of low-latency service data caused by network congestion.

Step 3-3: The first AP determines that the R-TWT SP information is obtained from the broadcast of the neighboring AP, and the first connection and the broadcast connection are STR (Simultaneous Transmitting and Receiving, The first connection and the broadcast connection are STR connection pairs, that is, service data can be sent and received synchronously under the first connection and the broadcast connection, that is, the service data transmission of the first AP under the first connection will not interfere with the service data transmission of the neighboring AP under the broadcast connection.

In this way, within the time indicated by the R-TWT SP information, the sleep period of the first AP under the first connection is planned not to overlap with the time indicated by the R-TWT SP information, that is, the first AP does not have to sleep within the time indicated by the R-TWT SP information, and can communicate normally without interfering with the business data transmission of the neighboring AP under the broadcast connection. Therefore, in the embodiment of the present disclosure, when the first connection and the broadcast connection are a STR connection pair, the sleep period of the first AP under the first connection can be planned not to overlap with the time indicated by the R-TWT SP information, which not only ensures the business data transmission of the neighboring AP under the broadcast connection, but also guarantees the communication of the STR connection pair, improves data transmission efficiency, and improves spectrum utilization.

It can be understood that in the embodiments of the present disclosure, the sleep period of the first AP under the broadcast connection does not overlap with the time indicated by the R-TWT SP information, which may include the situation where the sleep period does not overlap at all or partially overlaps with the R-TWT SP time; the embodiments of the present disclosure are not limited to this.

Optionally, the Broadcast TWT Parameter Set field of the R-TWT SP information may include first identification information, which identifies the scope of connections to which the R-TWT SP information applies; wherein the first identification information indicates that the scope of connections to which the R-TWT SP information applies includes the above-mentioned broadcast connection; or the first identification information indicates that the scope of connections to which the R-TWT SP information applies includes the above-mentioned multiple connections. The TID information of the broadcast connection may indicate that the service transmitted by the broadcast connection is a low-latency service. Optionally, the TID information may be, for example, TID-to-link mapping information.

Step 3-4: When the first AP determines that the R-TWT SP information is shared by the second AP and the first AP monitors the communication records of the neighboring AP, the sleep period of the first AP under at least one connection is planned to overlap with the time indicated by the R-TWT SP information. When the first AP monitors the communication records of the neighboring AP (for example, the communication records in the BSS where the neighboring AP is located), it can be predicted that During the time indicated by the R-TWT SP information, there may still be communication in the BSS where the neighbor AP is located. By planning the sleep period of the first AP under at least one connection to overlap with the time indicated by the R-TWT SP information, that is, during the time indicated by the R-TWT SP information, the first AP is in sleep mode under at least one connection, thereby preventing the first AP from interfering with the communication in the BSS where the neighbor AP is located.

In this way, without interfering with the transmission of business data within the time indicated by the R-TWT SP information, it is possible to plan the sleep cycle of the first AP under different connections according to different ways of obtaining the R-TWT SP information, thereby achieving rational use of spectrum resources, improving the utilization rate of spectrum resources, and achieving load balancing among multiple APs.

As shown in FIG. 2 , an embodiment of the present disclosure provides a sleep cycle negotiation method. Optionally, the method may be applied to a first access point device. Optionally, in an embodiment of the present disclosure, the first AP is, for example, a device having a wireless to wired bridging function, and the first AP is responsible for extending the services provided by the wired network to the wireless network.

The method may include the following steps:

Step 201, obtaining the R-TWT SP information of the neighboring AP;

Step 202: Plan a sleep period of the first AP under at least one connection according to the method for acquiring the R-TWT SP information of the neighboring AP; wherein the sleep period overlaps or does not overlap with the time indicated by the R-TWT SP information.

Generally, APs may include three forms, such as soft AP (or soft AP MLD), non-simultaneous transmitting and receiving (NSTR) mobile AP (or NSTR mobile AP MLD; mobile AP is mobile AP; AP MLD is Access Point Multi-Link Device) and regular AP (or regular AP MLD; regular AP is conventional AP), where regular AP is, for example, a router. Taking soft AP and NSTR mobile AP as examples, they are usually battery-powered, with high power consumption, and their communication with STA is usually not in a long-term continuous state. Therefore, it is necessary to provide a mechanism to support AP power saving. In the embodiment of the present disclosure, taking planning the sleep period of the first AP under at least one connection as an example, a mechanism to support AP power saving is provided.

The R-TWT SP information may include the transmission time parameter of the neighbor AP (i.e., the time indicated by the R-TWT SP information, that is, the time period during which the neighbor AP transmits service data to the AP associated with it), and may also include other information of the neighbor AP, such as the Broadcast TWT Parameter Set field, which is not limited here.

In the disclosed embodiment, the first AP obtains the R-TWT SP information of the neighbor AP, and the R-TWT SP information may be broadcast by the neighbor AP or shared by the second AP, without limitation. That is, the acquisition method of the R-TWT SP information may include: receiving the R-TWT SP information broadcast by the neighbor AP, receiving the R-TWT SP information shared by the second AP, etc.

Among them, in the embodiments of the present disclosure, unless otherwise specified, the neighbor AP refers to the neighbor AP of the first AP; in the case of special instructions, for example, if the neighbor AP is called AP-1, the second AP can be other APs among the neighbor APs of AP-1 except the first AP.

Optionally, the neighbor AP and the second AP may be subordinate APs of the same or different AP MLDs, or may be different AP MLDs or independent APs, and no limitation is made here. Optionally, the neighbor AP is subordinate to the first AP MLD, and the second AP is subordinate to the second AP MLD. The second AP may be in a certain location range or coverage range with the neighbor AP, so that the second AP can obtain parameter information of the neighbor AP, for example, the second AP can obtain R-TWT SP information of the neighbor AP.

Any two APs may perform data transmission via a beacon frame or a probe response frame, wherein the probe response frame may be an unsolicited probe response frame.

The first AP plans a sleep cycle (i.e., sleep time period) of the first AP under at least one connection according to a method for acquiring the R-TWT SP information; wherein the sleep cycle overlaps or does not overlap with the time indicated by the R-TWT SP information.

At least one connection includes a connection between the first AP and one STA, or a connection between the first AP and multiple STAs (that is, the first AP is a multi-connection access point device (Access Point Multi-Link Device, AP MLD)).

If the first AP is a multi-connection access point device, the sleep cycle of the first AP under each link can be independent of each other. For example, if at least one connection can include Link1, Link2 and Link3, and the sleep cycle of the first AP under Link1 is time period 1, then in this time period 1, the first AP is in a sleep state under Link1, and under Link2 or Link3, if the current moment If the first AP is not in the sleep period of Link 2 or Link 3, the first AP may not sleep to maintain service data transmission.

Optionally, the sleep cycle of the first AP under at least one connection overlaps or does not overlap with the time indicated by the R-TWT SP information, that is, whether the sleep cycle of the first AP under at least one connection is the same as the time indicated by the R-TWT SP information. For example, the time indicated by the R-TWT SP information includes time period 1, and the sleep cycle of the first AP under Link3 includes time period 2. If the sleep cycle of the first AP under Link1 overlaps with the time indicated by the R-TWT SP information, time period 2 is the same as time period 1; if the sleep cycle of the first AP under Link1 does not overlap with the time indicated by the R-TWT SP information, that is, time period 2 is different from time period 1, and there is no overlapping time period between the two.

When the first AP plans the sleep period of the first AP under each connection, it can first determine whether the service data transmission of the first AP under the connection conflicts with the service data transmission of the neighbor AP within the time indicated by the R-TWT SP information, and then plan the sleep period of the first AP under the connection based on whether there is a conflict between the two. Wherein, if there is no conflict between the two, the first AP can plan the sleep period of the first AP under the connection not to overlap with the time indicated by the R-TWT SP information, that is, within the time indicated by the R-TWT SP information, the first AP can perform service data transmission under the connection, and the neighbor AP can also perform service data transmission. If there is a conflict between the two, the first AP can plan the sleep period of the first AP under the connection to overlap with the time indicated by the R-TWT SP information, that is, within the time indicated by the R-TWT SP information, the first AP can sleep under the connection, and the neighbor AP can perform service data transmission, so as to avoid interference with the service data transmission performed by the neighbor AP due to the communication of the first AP when the neighbor AP performs service data transmission under the connection. In this way, the sleep cycle of the first AP under different connections can be reasonably planned without interfering with the business data transmission within the time indicated by the R-TWT SP information, providing a mechanism to support AP power saving.

Optionally, in the embodiment of the present disclosure, the method for obtaining the R-TWT SP information includes method 1 or method 2:

Method 1: receiving the R-TWT SP information broadcast by the neighbor AP;

Method 2: receiving the R-TWT SP information of the neighbor AP shared by the second AP.

Receive the R-TWT SP information broadcast by the neighbor AP, that is, the first AP can directly obtain the R-TWT SP information broadcast by the neighbor AP.

In the second method, the second AP shares the R-TWT SP information of the neighbor AP, that is, the first AP can obtain the R-TWT SP information of the neighbor AP through the forwarding operation of the second AP. Among them, business data can be transmitted between the neighbor AP and the second AP. Optionally, when the first AP and the neighbor AP cannot listen to each other, the first AP can obtain the R-TWT SP information of the neighbor AP by receiving the R-TWT SP information of the neighbor AP shared by the second AP.

In the disclosed embodiment, the first AP can obtain the R-TWT SP information of the neighbor AP through any one of the above methods, or can obtain the R-TWT SP information of the neighbor AP through both methods at the same time, and the specific method can be obtained according to the actual situation.

Optionally, in an embodiment of the present disclosure, according to a method for acquiring the R-TWT SP information of the neighboring AP, planning a sleep cycle of the first AP under at least one connection includes:

Plan the sleep period of the first AP under at least one connection to overlap with the time indicated by the R-TWT SP information, wherein the R-TWT SP information is obtained from the broadcast of the neighbor AP.

The planning of the sleep period of the first AP under at least one connection includes:

The Broadcast TWT Parameter Set field of the R-TWT SP information includes first identification information, where the first identification information indicates a scope of the connection to which the R-TWT SP information applies;

Planning a sleep cycle of the first AP under the broadcast connection; wherein the scope of the connection applied indicated by the first identification information includes: the broadcast connection of the broadcasted R-TWT SP information;

or

Planning the sleep cycle of the first AP under multiple connections; wherein the first identification information indicates that the range of the applied connections includes the multiple connections, and the TID information of the broadcast connection indicates that the service transmitted by the broadcast connection is a low-latency service.

Broadcast connection, that is, the connection of broadcast R-TWT SP information. When the neighbor AP broadcasts R-TWT SP information, the connection between the first AP and the second AP is a broadcast connection.

As an example, the format of the Broadcast TWT Parameter Set field may be as shown in Table 1 below:

Table 1:

Among them, the format of the request type field in the Broadcast TWT Parameter Set field can be as shown in Table 2 below:

Table 2:

For example, the Aligned subfield of the request type field in the Broadcast TWT Parameter Set field can be used, and the Aligned subfield can be set to different values as the first identification information to identify the range of connections to which the R-TWT SP information applies. Exemplarily, when the Aligned subfield is set to a value of 0, the first identification information indicates that the range of connections to which the R-TWT SP information applies includes: broadcast connections of the broadcast R-TWT SP information; when the Aligned subfield is set to a value of 1, the range of connections to which the R-TWT SP information applies includes multiple connections.

In the embodiment of the present disclosure, the TID information may be, for example, TID-to-link mapping information. Optionally, a subfield associated with the TID-to-link mapping information in the target wake-up time transmission information field may be used as the TID-to-link mapping information.

The format of the target wake-up time transmission information field may be as shown in Table 3 below:

Table 3:

For example, the Restricted TWT DL TID Bitmap subfield and/or the Restricted TWT UL TID Bitmap in the restricted target wake-up time transmission information field may be used to set the Restricted TWT DL TID Bitmap subfield and the Restricted TWT UL TID Bitmap subfield to different values as TID-to-link mapping information. For example, when the Restricted TWT DL TID Bitmap subfield is set to a first value, it indicates that the downlink transmission service transmitted by the broadcast connection is a low-latency service. When the Restricted TWT UL TID Bitmap subfield is set to a second value, it indicates that the uplink transmission service transmitted by the broadcast connection is a low-latency service.

In the embodiment of the present disclosure, the first identification information indicates the connection to which the R-TWT SP information is applied. The scope of connection includes the above-mentioned broadcast connection, that is, within the time indicated by the R-TWT SP information, the neighbor AP performs business data transmission under the broadcast connection, and the sleep period of the first AP under the broadcast connection is planned to overlap with the time indicated by the R-TWT SP information, that is, the first AP sleeps under the broadcast connection, so as to avoid the neighbor AP performing business data transmission under the broadcast connection, and the first AP communicates and interferes with the business data transmission performed by the neighbor AP.

When the first identification information indicates that the scope of connections to which the R-TWT SP information applies includes multiple connections, and the TID information indicates that the service transmitted by the broadcast connection is a low-latency service, the sleep periods of the first AP under multiple connections are planned to overlap with the time indicated by the R-TWT SP information, that is, the first AP sleeps under the broadcast connection, thereby avoiding interference with the low-latency service data transmission performed by the neighboring AP due to communication when the neighboring AP transmits low-latency service data under the broadcast connection, thereby ensuring the transmission of low-latency service data and avoiding transmission delays of low-latency service data caused by network congestion.

Optionally, in an embodiment of the present disclosure, the sleep period of the first AP under the first connection is planned not to overlap with the time indicated by the R-TWT SP information, wherein the first connection and the broadcast connection are a STR connection pair.

The first connection and the broadcast connection are mutually STR connection pairs, that is, service data can be sent and received synchronously under the first connection and the broadcast connection, that is, service data transmission under the first connection will not interfere with service data transmission under the broadcast connection.

Furthermore, within the time indicated by the R-TWT SP information, the transmission of business data under the first connection will not interfere with the transmission of business data under the broadcast connection. The sleep period of the first AP under the first connection can be planned so as not to overlap with the time indicated by the R-TWT SP information, thereby achieving reasonable planning of the sleep period of the first AP under the first connection without interfering with the transmission of business data within the time indicated by the R-TWT SP information.

Optionally, in the embodiment of the present disclosure, the step of planning a sleep cycle of the first AP under at least one connection according to a method of acquiring the R-TWT SP information of the neighboring AP includes:

Planning the sleep cycle of the first AP under at least one connection and the R-TWT SP signal The time indicated by the information overlaps, wherein the R-TWT SP information is shared by the second AP, and the first AP monitors the communication record of the neighbor AP.

The first AP can monitor the communication record of the neighboring AP through the information reported by the STA associated with the first AP under any connection in the at least one connection. Specifically, the STA associated with the first AP in any connection can report the information to AP1 when collecting communications of other BSSs (for example, the BSS where the neighboring AP is located; where BSS is Basic Service Sets Basic Service Set). The reported information may include BSSID information and BSS color information of other BSSs collected by the STA, for example, BSSID information and BSS color information of the BSS where the neighboring AP is located.

When the first AP monitors the communication record of the neighboring AP, it can be predicted that the BSS where the neighboring AP is located may still communicate within the time indicated by the R-TWT SP information. By planning the sleep period of the first AP under at least one connection to overlap with the time indicated by the R-TWT SP information, that is, within the time indicated by the R-TWT SP information, the first AP sleeps under at least one connection, and the BSS where the neighboring AP is located can still communicate. It can be achieved that within the time indicated by the R-TWT SP information, the first AP communicates and interferes with the communication within the BSS where the neighboring AP is located. For example, if at least one connection includes Link4, then if the R-TWT SP information is shared by the second AP, and the STA associated with the first AP under Link4 monitors the communication record of the neighboring AP, the sleep period of the first AP under the Link4 can be planned to overlap with the time indicated by the R-TWT SP information.

In the disclosed embodiment, the first AP obtains the R-TWT SP information of the neighboring AP, and plans the sleep cycle of the first AP under at least one connection according to the method of obtaining the R-TWT SP information; wherein the sleep cycle overlaps or does not overlap with the time indicated by the R-TWT SP information; thus, the sleep cycle of the first AP under different connections can be planned according to different methods of obtaining the R-TWT SP information without interfering with the transmission of service data within the time indicated by the R-TWT SP information. The disclosed embodiment provides a mechanism to support AP power saving.

Referring to FIG. 3 , the present disclosure also provides a sleep mechanism negotiation method, which is applied to neighbor According to the AP, the method may include the following steps:

Step 301: Broadcast the R-TWT SP information of the neighbor AP;

The R-TWT SP information instructs the first AP to plan a sleep period of the first AP under at least one connection according to a method for obtaining the R-TWT SP information; wherein the sleep period overlaps or does not overlap with the time indicated by the R-TWT SP information.

Generally, APs may include three forms, such as soft AP (or soft AP MLD), NSTR mobile AP (or NSTR mobile AP MLD; mobile AP is mobile AP; AP MLD is Access Point Multi-Link Device, multi-connection access point device) and regular AP (or regular AP MLD; regular AP is conventional AP), where regular AP is, for example, a router. Taking soft AP and NSTR mobile AP as examples, they are usually battery-powered, with high power consumption, and their communication with STA is usually not in a long-term continuous state. Therefore, it is necessary to provide a mechanism to support AP power saving. In the embodiment of the present disclosure, taking the example of instructing a first AP to plan a sleep period of the first AP under at least one connection, a mechanism to support AP power saving is provided.

The R-TWT SP information may include the transmission time parameter of the neighbor AP (i.e., the time indicated by the R-TWT SP information, that is, the time period during which the neighbor AP transmits service data to the AP associated with it), and may also include other information of the neighbor AP, such as the Broadcast TWT Parameter Set field, which is not limited here.

By broadcasting the R-TWT SP information of the neighbor AP through the neighbor AP, the first AP can directly obtain the R-TWT SP information broadcast by the neighbor AP.

In the disclosed embodiment, the neighbor AP may also send R-TWT SP information to the second AP, instructing the second AP to share the R-TWT SP information with the first AP. Optionally, in the case where the neighbor AP and the first AP cannot listen to each other, the neighbor AP may send R-TWT SP information to the second AP, instructing the second AP to share the R-TWT SP information with the first AP, so that the first AP obtains the R-TWT SP information of the neighbor AP. That is, the way in which the first AP obtains the R-TWT SP information of the neighbor AP may include: receiving the R-TWT SP information broadcast by the neighbor AP, receiving the R-TWT SP information shared by the second AP, etc.

In the embodiment of the present disclosure, unless otherwise specified, the neighbor AP refers to the first AP neighbor AP; for example, in special cases, if the neighbor AP is called AP-1, the second AP may be any other AP among the neighbor APs of the AP-1 except the first AP.

Optionally, the neighbor AP and the second AP may be subordinate APs of the same or different AP MLDs, or may be different AP MLDs or independent APs, and no limitation is made here. Optionally, the neighbor AP is subordinate to the first AP MLD, and the second AP is subordinate to the second AP MLD. The second AP may be in a certain location range or coverage range with the neighbor AP, so that the second AP can obtain parameter information of the neighbor AP, for example, the second AP can obtain R-TWT SP information of the neighbor AP.

The first AP plans a sleep cycle (i.e., sleep time period) of the first AP under at least one connection according to a method for acquiring the R-TWT SP information; wherein the sleep cycle overlaps or does not overlap with the time indicated by the R-TWT SP information.

At least one connection includes a connection between the first AP and a STA, or a connection between the first AP and multiple STAs (that is, the first AP is a multi-connection access point device (Access Point Multi-Link Device, AP MLD)). Among them, if the first AP is a multi-connection access point device, the sleep cycle of the first AP under each Link can be independent of each other. For example, if at least one connection may include Link1, Link2 and Link3, and the sleep cycle of the first AP under Link1 is time period 1, then in this time period 1, the first AP is in a sleep state under Link1, and under Link2 or Link3, if it is not in the sleep cycle of Link2 or Link3 at the current moment, the first AP may not sleep to maintain business data transmission.

Optionally, the sleep cycle of the first AP under at least one connection overlaps or does not overlap with the time indicated by the R-TWT SP information, that is, whether the sleep cycle of the first AP under at least one connection is the same as the time indicated by the R-TWT SP information. For example, the time indicated by the R-TWT SP information includes time period 1, and the sleep cycle of the first AP under Link3 includes time period 2. If the sleep cycle of the first AP under Link1 overlaps with the time indicated by the R-TWT SP information, time period 2 is the same as time period 1; if the sleep cycle of the first AP under Link1 does not overlap with the time indicated by the R-TWT SP information, that is, time period 2 is different from time period 1, and there is no overlapping time period between the two.

When instructing the first AP to plan the sleep period of the first AP in each connection, it can first be determined whether the first AP performs service data transmission in the connection and whether it is connected to the neighboring AP in the R-TWT SP There is a conflict in the transmission of business data within the time indicated by the information, and then based on whether there is a conflict between the two, instruct the first AP to plan the sleep period of the first AP under the connection. Among them, if there is no conflict between the two, the first AP can be instructed to plan the sleep period of the first AP under the connection so that it does not overlap with the time indicated by the R-TWT SP information, that is, within the time indicated by the R-TWT SP information, the first AP can perform business data transmission under the connection, and the neighbor AP can also perform business data transmission. In the case of a conflict between the two, the first AP can be instructed to plan the sleep period of the first AP under the connection to overlap with the time indicated by the R-TWT SP information, that is, within the time indicated by the R-TWT SP information, the first AP can sleep under the connection, and the neighbor AP can perform business data transmission, so as to avoid the first AP communicating and interfering with the business data transmission performed by the neighbor AP when the neighbor AP performs business data transmission under the connection. In this way, the first AP can be reasonably instructed to plan the sleep period of the first AP under different connections without interfering with the business data transmission within the time indicated by the R-TWT SP information, providing a mechanism to support AP power saving.

Optionally, in an embodiment of the present disclosure, the Broadcast TWT Parameter Set field of the R-TWT SP information includes first identification information, where the first identification information indicates a range of connections to which the R-TWT SP information applies;

The R-TWT SP information indicates to the first AP that: a sleep period of the first AP under the broadcast connection is planned to overlap with the time indicated by the R-TWT SP information; wherein the scope of the connection applied by the first identification information indication includes: a broadcast connection of the broadcast R-TWT SP information;

or

The R-TWT SP information indicates to the first AP that: the sleep periods of the first AP under multiple connections are planned to overlap with the times indicated by the R-TWT SP information respectively; the first identification information indicates that the scope of the applied connection includes multiple connections, and the TID information of the broadcast connection indicates that the service transmitted by the broadcast connection is a low-latency service.

A broadcast connection is a connection of broadcast R-TWT SP information. For example, when a first AP receives R-TWT SP information broadcast by a neighboring AP, the connection between the first AP and the second AP is a broadcast connection.

As an example, the format of the Broadcast TWT Parameter Set field can be as shown in the aforementioned Table 1; the format of the request type field in the Broadcast TWT Parameter Set field can be as shown in the aforementioned Table 2. For example, the Aligned subfield of the request type field in the Broadcast TWT Parameter Set field can be used, and the Aligned subfield can be set to different values as the first identification information to identify the range of connections to which the R-TWT SP information applies. Exemplarily, when the Aligned subfield is set to a value of 0, the first identification information indicates that the range of connections to which the R-TWT SP information applies includes: broadcast connections of the broadcast R-TWT SP information; when the Aligned subfield is set to a value of 1, the range of connections to which the R-TWT SP information applies includes multiple connections.

In the embodiment of the present disclosure, the TID information may be, for example, TID-to-link mapping information. Optionally, a subfield associated with the TID-to-link mapping information in the target wake-up time transmission information field may be used as the TID-to-link mapping information.

Among them, the format of the restricted target wake-up time transmission information field can be as shown in the aforementioned Table 3. For example, the Restricted TWT DL TID Bitmap subfield and/or the Restricted TWT UL TID Bitmap in the restricted target wake-up time transmission information field can be used to set the Restricted TWT DL TID Bitmap subfield and the Restricted TWT UL TID Bitmap subfield to different values as TID-to-link mapping information. For example, when the Restricted TWT DL TID Bitmap subfield is set to the first value, it indicates that the downlink transmission service transmitted by the broadcast connection is a low-latency service. When the Restricted TWT UL TID Bitmap subfield is set to the second value, it indicates that the uplink transmission service transmitted by the broadcast connection is a low-latency service.

In the embodiment of the present disclosure, when the first identification information indicates that the scope of the connection to which the R-TWT SP information applies includes the above-mentioned broadcast connection, that is, within the time indicated by the R-TWT SP information, the neighbor AP performs business data transmission under the broadcast connection, and by instructing the first AP to plan the sleep period of the first AP under the broadcast connection to overlap with the time indicated by the R-TWT SP information, that is, the first AP sleeps under the broadcast connection, it is avoided that when the neighbor AP performs business data transmission under the broadcast connection, the first AP communicates and interferes with the business data transmission performed by the neighbor AP.

When the first identification information indicates that the range of connections to which the R-TWT SP information applies includes multiple connections, and the TID information indicates that the service transmitted by the broadcast connection is a low-latency service, by indicating The first AP plans that the sleep periods of the first AP under multiple connections overlap with the time indicated by the R-TWT SP information, that is, the first AP sleeps under the broadcast connection, so as to avoid interference with the low-latency service data transmission performed by the neighboring AP due to the communication of the first AP when the neighboring AP performs low-latency service data transmission under the broadcast connection, thereby ensuring the transmission of low-latency service data and avoiding transmission delay of low-latency service data caused by network congestion.

Optionally, in an embodiment of the present disclosure, the R-TWT SP information indicates to the first AP: a sleep period of the first AP planned under the first connection does not overlap with the time indicated by the R-TWT SP information, wherein the first connection and the broadcast connection are a STR connection pair.

The first connection and the broadcast connection are mutually STR connection pairs, that is, service data can be sent and received synchronously under the first connection and the broadcast connection, that is, service data transmission under the first connection will not interfere with service data transmission under the broadcast connection.

Furthermore, within the time indicated by the R-TWT SP information, the transmission of business data under the first connection will not interfere with the transmission of business data under the broadcast connection. The first AP can be instructed to plan the sleep period of the first AP under the first connection so that it does not overlap with the time indicated by the R-TWT SP information, thereby achieving reasonable planning of the sleep period of the first AP under the first connection without interfering with the transmission of business data within the time indicated by the R-TWT SP information.

Optionally, in the embodiment of the present disclosure, the following steps may also be included:

Send the R-TWT SP information to the second AP, instructing the second AP to share the R-TWT SP information with the first AP.

Optionally, the neighbor AP can directly broadcast the R-TWT SP information of the neighbor AP so that the first AP can obtain the R-TWT SP information. It is also possible to send the R-TWT SP information to the second AP and instruct the second AP to forward the R-TWT SP information to the first AP so that the first AP can obtain the R-TWT SP information to ensure that the first AP can obtain the R-TWT SP information. For example, when the first AP and the neighbor AP cannot monitor each other, the R-TWT SP information can be forwarded to the first AP through the neighbor AP, so that the first AP can obtain the R-TWT SP information of the neighbor AP.

Optionally, the embodiments of the present disclosure do not limit the neighbor AP's own R-TWT SP information and the order of operations for sending R-TWT SP information to the second AP.

By sending R-TWT SP information to the second AP and instructing the second AP to share the R-TWT SP information with the first AP, the way in which the first AP obtains the R-TWT SP information of the neighboring AP can be enriched.

In the disclosed embodiment, the neighbor AP broadcasts its own R-TWT SP information; wherein the R-TWT SP information instructs the first AP to plan the sleep period of the first AP under at least one connection according to the method of obtaining the R-TWT SP information; wherein the sleep period overlaps or does not overlap with the time indicated by the R-TWT SP information; in this way, the first AP can directly obtain the R-TWT SP information of the neighbor AP through the broadcast of the neighbor AP, and without interfering with the service data transmission within the time indicated by the R-TWT SP information, according to different methods of obtaining the R-TWT SP information, plan the sleep period of the first AP under different connections. The disclosed embodiment provides a mechanism to support AP power saving.

Referring to FIG. 4 , an embodiment of the present disclosure further provides a sleep cycle negotiation method, which is applied to a second AP. The method may include the following steps:

Step 401: receiving R-TWT SP information of a neighbor AP sent by a neighbor AP of a first AP, and sharing the R-TWT SP information with the first AP;

The R-TWT SP information instructs the first AP to plan a sleep period of the first AP under at least one connection according to a method for obtaining the R-TWT SP information; wherein the sleep period overlaps or does not overlap with the time indicated by the R-TWT SP information.

Generally, APs can include three types, such as soft AP (or soft AP MLD), non-simultaneous transmitting and receiving (NSTR, Non-Simultaneous Transmitting and Receiving) mobile AP (or NSTR mobile AP MLD) and regular AP (or regular AP MLD), where regular AP is, for example, a router. Taking soft AP and NSTR mobile AP as examples, they are usually powered by batteries, with high power consumption, and their communication with STA is usually not in a long-term continuous state. Therefore, it is necessary to provide a mechanism to support AP power saving. In the embodiment of the present disclosure, taking the planning of the sleep period of the first AP under at least one connection as an example, a mechanism to support AP power saving is provided. mechanism.

The R-TWT SP information may include the transmission time parameter of the neighbor AP (i.e., the time indicated by the R-TWT SP information, that is, the time period during which the neighbor AP transmits service data to the AP associated with it), and may also include other information of the neighbor AP, such as the Broadcast TWT Parameter Set field, which is not limited here.

Optionally, the second AP can receive the R-TWT SP information sent by the neighbor AP and share the R-TWT SP information with the first AP. Optionally, when the first AP and the neighbor AP cannot listen to each other, the second AP can forward the received R-TWT SP information of the neighbor AP of the first AP to the first AP, so that the first AP can obtain the R-TWT SP information of the neighbor AP.

The second AP may be an AP other than the first AP among the neighbor APs of the neighbor AP. Optionally, the neighbor AP and the second AP may be subordinate APs of the same or different AP MLDs, or different AP MLDs or independent APs, which are not limited here. Optionally, the neighbor AP is subordinate to the first AP MLD, and the second AP is subordinate to the second AP MLD. The second AP may be in a certain location range or coverage range with the neighbor AP, so that the second AP can obtain the parameter information of the neighbor AP, for example, the second AP can obtain the R-TWT SP information of the neighbor AP.

Optionally, the first AP may also obtain the R-TWT SP information of the neighbor AP by directly receiving the broadcast of the neighbor AP. That is, the first AP may obtain the R-TWT SP information of the neighbor AP by: receiving the R-TWT SP information broadcast by the neighbor AP, receiving the R-TWT SP information of the neighbor AP shared by the second AP, etc.

The first AP plans a sleep cycle (i.e., sleep time period) of the first AP under at least one connection according to a method for acquiring the R-TWT SP information; wherein the sleep cycle overlaps or does not overlap with the time indicated by the R-TWT SP information.

At least one connection includes a connection between the first AP and a STA, or a connection between the first AP and multiple STAs (i.e., the first AP is a multi-link access point device (Access Point Multi-Link Device, AP MLD)). If the first AP is a multi-link access point device, the sleep cycle of the first AP under each link can be independent of each other. For example, if at least one connection can include Including Link1, Link2 and Link3, the sleep period of the first AP under Link1 is time period 1, then in this time period 1, the first AP is in sleep state under Link1, and under Link2 or Link3, if the current moment is not in the sleep period of Link2 or Link3, the first AP may not sleep to maintain business data transmission.

Optionally, the sleep cycle of the first AP under at least one connection overlaps or does not overlap with the time indicated by the R-TWT SP information, that is, whether the sleep cycle of the first AP under at least one connection is the same as the time indicated by the R-TWT SP information. For example, the time indicated by the R-TWT SP information includes time period 1, and the sleep cycle of the first AP under Link3 includes time period 2. If the sleep cycle of the first AP under Link1 overlaps with the time indicated by the R-TWT SP information, time period 2 is the same as time period 1; if the sleep cycle of the first AP under Link1 does not overlap with the time indicated by the R-TWT SP information, that is, time period 2 is different from time period 1, and there is no overlapping time period between the two.

When instructing the first AP to plan the sleep period of the first AP under each connection, it can be first determined whether the service data transmission of the first AP under the connection conflicts with the service data transmission of the neighbor AP within the time indicated by the R-TWT SP information, and then based on whether there is a conflict between the two, the first AP is instructed to plan the sleep period of the first AP under the connection. Wherein, if there is no conflict between the two, the first AP can plan the sleep period of the first AP under the connection not to overlap with the time indicated by the R-TWT SP information, that is, within the time indicated by the R-TWT SP information, the first AP can be instructed to perform service data transmission under the connection, and the neighbor AP can also perform service data transmission. If there is a conflict between the two, the first AP can be instructed to plan the sleep period of the first AP under the connection to overlap with the time indicated by the R-TWT SP information, that is, within the time indicated by the R-TWT SP information, the first AP can sleep under the connection, and the neighbor AP can perform service data transmission, so as to avoid interference with the service data transmission performed by the neighbor AP due to the communication of the first AP when the neighbor AP performs service data transmission under the connection. In this way, the first AP can be reasonably instructed to plan the sleep cycle of the first AP under different connections without interfering with the service data transmission within the time indicated by the R-TWT SP information, thereby providing a mechanism to support AP power saving.
