The following description of the technical solutions in the embodiments of the present disclosure will be made clearly and completely with reference to the accompanying drawings in the embodiments of the present disclosure, and it is apparent that the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments that a person of ordinary skill in the art would obtain without making any inventive effort are within the scope of protection of this disclosure.

The embodiment of the disclosure provides a sleep period negotiation method, electronic equipment and a storage medium, which are used for providing a mechanism for supporting AP (Access Point) power saving.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

As a first example, referring to fig. 1, fig. 1 illustrates an application scenario example in which embodiments of the present disclosure provide a sleep period negotiation method. The method comprises the steps of 1-1 or 1-2, wherein a first AP acquires R-TWT SP of a neighbor AP.

In the embodiment of the disclosure, a neighboring AP is, for example, an AP that is closer to the first AP in a logical topology, for example, an AP that has a higher signal strength received by the first AP, or an AP that is physically closer to the first AP, or an AP that is in the same basic service set (Basic Service Set, BSS) as the first AP; in WLAN, the AP may obtain basic service set identification (Basic Service Set identifier, BSSID) sent by other APs through channel sounding to discover neighbor APs. The neighbor AP can be recommended to the STA as a better roaming target; in addition, the frequency spectrum resources can be fully utilized by considering the neighbor APs when the radio frequency parameters are adjusted, and load balancing among a plurality of APs can be realized.

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

or (b)

Step 1-2: and the neighbor AP sends the R-TWT SP information to the second AP, and instructs the second AP to share the R-TWT SP information to the first AP.

In the embodiment of the present disclosure, the neighbor AP refers to a neighbor AP of the first AP without special description; in the specific case, for example, if the neighboring AP is referred to as AP-1, the second AP may be another AP other than the first AP among the neighboring APs of the AP-1.

Alternatively, embodiments of the present disclosure do not limit the order of execution of 1-1 and 1-2.

Step 2: the first AP acquires the R-TWT SP information of the neighbor AP in any mode, and determines the acquisition mode of the R-TWT SP information.

Step 3: and the first AP plans the dormancy period of the first AP under at least one connection according to the acquisition mode of the R-TWT SP information. Specifically:

step 3-1: when the first AP determines that the R-TWT SP information is acquired from broadcasting of the neighbor AP and the R-TWT SP information is applied to broadcasting connection for broadcasting the R-TWT SP information, the dormancy period of the first AP under the broadcasting connection is planned to overlap with the time indicated by the R-TWT SP information. Specifically, when the R-TWT SP information is applied to the broadcast connection, that is, in the time indicated by the R-TWT SP information, the neighboring AP may transmit low latency traffic data under the broadcast connection.

And planning that the dormancy period of the first AP under the broadcast connection overlaps with the time indicated by the R-TWT SP information in the time indicated by the R-TWT SP information, namely, the first AP sleeps under the broadcast connection in the R-TWT SP, so that the first AP communicates and interference is caused to service data transmission of the neighbor AP under the broadcast connection in the time indicated by the R-TWT SP information is avoided.

It may be appreciated that in the embodiment of the present disclosure, the sleep period of the first AP under broadcast connection overlaps with the time indicated by the R-TWT SP information, which may include a case where the sleep period overlaps with the time of the R-TWT SP partially or completely; the embodiments of the present disclosure are not limited in this regard.

Step 3-2: the first AP obtains broadcasting from the neighbor AP in determining that the R-TWT SP information includes: and when the service transmitted by the broadcast connection is a low-delay service, planning that the dormancy period of the first AP under the connection overlaps with the time indicated by the R-TWT SP information.

In the same way, in the time indicated by the R-TWT SP information, the dormancy period of the first AP under the broadcast connection is planned to be overlapped with the time indicated by the R-TWT SP information, namely, the first AP is dormant under the broadcast connection in the R-TWT SP, so that the first AP is prevented from communicating to cause interference to the transmission of the service data of the neighbor AP under the broadcast connection in the time indicated by the R-TWT SP information, the transmission of the low-delay service data is ensured, and the transmission delay of the low-delay service data caused by network congestion is avoided.

Step 3-3: and when the first AP determines that the R-TWT SP information is acquired from the broadcasting of the neighbor AP and the first connection and the broadcasting connection are STR (Simultaneous Transmitting and Receiving, simultaneous transceiving) connection pairs, planning that the dormancy period of the first AP under the first connection is not overlapped with the time indicated by the R-TWT SP information. The first connection and the broadcast connection are STR connection pairs, namely, the service data can be synchronously transmitted and received under the first connection and the broadcast connection, namely, the service data transmission of the first AP under the first connection does not interfere the service data transmission of the neighbor AP under the broadcast connection.

In this way, the dormancy period of the first AP under the first connection is planned to be not overlapped with the time indicated by the R-TWT SP information in the time indicated by the R-TWT SP information, namely, the first AP does not need to be dormant in the time indicated by the R-TWT SP information, and can normally communicate without causing interference to the service data transmission of the neighbor AP under the broadcast connection. Therefore, in the embodiment of the present disclosure, when the first connection and the broadcast connection are STR connection pairs, it may be planned that the sleep period of the first AP under the first connection is not overlapped with the time indicated by the R-TWT SP information, so that service data transmission of the neighboring AP under the broadcast connection is ensured, and also the communication condition of the STR connection pairs is ensured, thereby improving the data transmission efficiency and the spectrum utilization rate.

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

Alternatively, a Broadcast TWT Parameter Set (broadcast target wake time parameter set) field of the R-TWT SP information may include first identification information identifying a range of a connection to which the R-TWT SP information applies; wherein the first identification information indicates that a range of a connection to which the R-TWT SP information is applied includes the broadcast connection; or the first identification information indicates that the range of the connection to which the R-TWT SP information applies includes the above-described plurality of connections. The TID information of the broadcast connection may indicate that the service transmitted by the broadcast connection is a low latency service. Alternatively, the TID information may be TID-to-link mapping information, for example.

Step 3-4: and 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 neighbor APs, planning that the dormancy period of the first AP under at least one connection overlaps with the time indicated by the R-TWT SP information. When the first AP monitors the communication record of the neighboring AP (for example, the record of the communication in the BSS where the neighboring AP is located), it may be predicted that there may still be a situation where the communication is performed in the BSS where the neighboring AP is located in the time indicated by the R-TWT SP information. By planning that the dormancy period of the first AP under at least one connection overlaps with the time indicated by the R-TWT SP information, that is, the first AP sleeps under at least one connection in the time indicated by the R-TWT SP information, the first AP is prevented from interfering with communication in the BSS where the neighbor AP is located.

Therefore, the sleep period of the first AP under different connections can be planned according to different acquisition modes of the R-TWT SP information while the transmission of the service data in the time indicated by the R-TWT SP information is not interfered, the reasonable utilization of spectrum resources is realized, the utilization rate of the spectrum resources is improved, and the load balancing among a plurality of APs is realized.

As shown in fig. 2, embodiments of the present disclosure provide a sleep period negotiation method, optionally applicable to a first access point device; optionally, in an embodiment of the disclosure, the first AP is, for example, a device with a wireless-to-wired Bridging (Bridging) function, and the first AP is responsible for extending a service provided by the wired network to the wireless network.

The method may comprise the steps of:

step 201, acquiring R-TWT SP information of a neighbor AP;

step 202, planning a sleep period of the first AP under at least one connection according to an acquisition mode of the R-TWT SP information of the neighbor AP; wherein the sleep period overlaps or does not overlap with the time indicated by the R-TWT SP information.

Typically, the APs may include three forms, such as soft AP (or soft AP MLD), mobile AP (or NSTR mobile AP MLD; mobile AP; AP MLD: access Point Multi-Link Device; multiple connectivity access point Device) which is Non-simultaneous transceiving (NSTR, non-Simultaneous Transmitting and Receiving) and regular AP (or regular AP), wherein regular AP is a router, for example. Taking soft AP and NSTR mobile AP as examples, battery power is usually used, power consumption is high, and communication with STA is not in long continuous state, so a mechanism for supporting AP power saving needs to be provided. 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 for supporting power saving of the AP is provided.

The R-TWT SP information may include a transmission time parameter of the neighboring AP (i.e., a time indicated by the R-TWT SP information, i.e., a time period during which the neighboring AP performs service data transmission with its associated AP), or may include other information of the neighboring AP, such as a Broadcast TWT Parameter Set field, which is not limited herein.

In the embodiment of the disclosure, the first AP acquires R-TWT SP information of the neighboring AP, where the R-TWT SP information may be broadcasted by the neighboring AP or may be shared by the second AP, and is not limited herein. Namely, the acquisition mode of the R-TWT SP information can comprise the following steps: receiving R-TWT SP information broadcast by a neighbor AP, receiving R-TWT SP information shared by a second AP by the neighbor AP, and the like.

Alternatively, the neighboring AP and the second AP may be accessory APs of the same or different AP MLDs, or may be different AP MLDs or independent APs, which is not limited herein. Optionally, the neighboring AP is attached to the first AP MLD, the second AP is attached to the second AP MLD, and the second AP may be in a certain location range or coverage with the neighboring AP, so that the second AP may obtain parameter information of the neighboring AP, for example, the second AP may obtain R-TWT SP information of the neighboring AP.

Any two APs may transmit data 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 dormancy period (namely a dormancy time period) of the first AP under at least one connection according to an acquisition mode of the R-TWT SP information; wherein the sleep period overlaps or does not overlap with the time indicated by the R-TWT SP information.

The at least one connection includes a connection of the first AP with one STA or a connection of the first AP with a plurality of STAs (i.e., the first AP is a multi-connection access point Device (AP MLD)).

If the first AP is a multi-connection AP device, the first AP may be independent of each other between sleep periods under each Link. For example, if the at least one connection may include Link1, link2, and Link3, the sleep period of the first AP under Link1 is a period 1, then in this period 1, the first AP is in a sleep state under Link1, and under Link2 or Link3, if the current time is not in the sleep period of Link2 or Link3, the first AP may not sleep, so as to maintain the traffic data transmission.

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

When the first AP plans a sleep period of the first AP under each connection, it may first determine whether the first AP performs service data transmission under the connection, and whether there is a conflict with the neighbor AP performing service data transmission in 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. Under the condition that the two do not have conflict, the first AP can plan that the dormancy period of the first AP under the connection is not overlapped with the time indicated by the R-TWT SP information, namely, the first AP can perform service data transmission under the connection in the time indicated by the R-TWT SP information, and the neighbor AP can also perform service data transmission. Under the condition that the two conflict, the first AP can plan that the dormancy period of the first AP under the connection overlaps with the time indicated by the R-TWT SP information, namely, the first AP can dormancy under the connection in the time indicated by the R-TWT SP information, and the neighbor AP can conduct business data transmission, so that when the neighbor AP conducts business data transmission under the connection, the first AP conducts communication to cause interference to the business data transmission conducted by the neighbor AP. Therefore, the sleep period of the first AP under different connections can be reasonably planned while the transmission of service data in the time indicated by the R-TWT SP information is not interfered, and a mechanism for supporting the power saving of the AP is provided.

Optionally, in an embodiment of the present disclosure, the acquiring manner of the R-TWT SP information includes a first manner or a second manner:

in a first mode, receiving R-TWT SP information broadcasted by the neighbor AP;

and in a second mode, receiving R-TWT SP information shared by the second AP and the neighbor AP.

And receiving the R-TWT SP information broadcast by the neighbor AP, namely the first AP can directly acquire the R-TWT SP information broadcast by the neighbor AP.

In a second mode, the second AP is received to share the R-TWT SP information of the neighbor AP, namely, the first AP can acquire the R-TWT SP information of the neighbor AP through forwarding operation of the second AP. And the service data transmission can be performed between the neighbor AP and the second AP. Optionally, under the condition that the first AP and the neighbor AP cannot monitor each other, the first AP may obtain R-TWT SP information of the neighbor AP by receiving R-TWT SP information of the second AP sharing the neighbor AP.

In the embodiment of the present disclosure, the first AP may acquire R-TWT SP information of the neighboring AP through any one of the above manners, or may acquire R-TWT SP information of the neighboring AP in two manners at the same time, and may specifically acquire the R-TWT SP information of the neighboring AP according to an actual situation.

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

And planning that the dormancy period of the first AP under at least one connection overlaps with the time indicated by the R-TWT SP information, wherein the R-TWT SP information is obtained from the broadcasting of the neighbor AP.

Wherein the planning 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 indicating a range of a connection to which the R-TWT SP information is applied;

planning a sleep period of the first AP under the broadcast connection; wherein the first identification information indicates a range of the applied connection including: said broadcast connection of said broadcasted R-TWT SP information;

or (b)

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

Broadcast connection, i.e. connection of broadcasted R-TWT SP information. For example, when the 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 (broadcast TWT parameter set) field may be as shown in table 1 below:

table 1:

the format of the request type field in the Broadcast TWT Parameter Set (broadcast TWT parameter set) field may 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 may be set to a different value as the first identification information to identify the range of connection to which the R-TWT SP information is applied. Illustratively, when the Aligned subfield is set to a value of 0, identifying that the first identification information indicates a range of connections to which the R-TWT SP information applies includes: broadcast connection of broadcasted R-TWT SP information; when the Aligned subfield is set to a value of 1, the range of connections to which the identification R-TWT SP information is applied includes a plurality of connections.

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

The format of the limited target wake-up time transmission information field may be as follows in table 3:

Table 3:

for example, the Restricted TWT DL TID Bitmap subfield and/or Restricted TWT UL TID Bitmap in the constraint target wakeup 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 the first value, the downlink traffic transmitted by the broadcast connection is indicated as low-latency traffic. When the Restricted TWT UL TID Bitmap subfield is set to the second value, the uplink traffic transmitted by the broadcast connection is indicated as low latency traffic.

In the embodiment of the disclosure, when the range of the connection to which the first identification information indicates that the R-TWT SP information is applied includes the broadcast connection, that is, in the time indicated by the R-TWT SP information, the neighboring AP performs service data transmission under the broadcast connection, and by planning that the sleep period of the first AP under the broadcast connection overlaps 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 neighboring AP performs service data transmission under the broadcast connection, the first AP performs communication and interferes with the service data transmission performed by the neighboring AP.

When the first identification information indicates that the range of the connection to which the R-TWT SP information is applied comprises a plurality of connections and the TID information indicates that the service transmitted by the broadcast connection is low-delay service, the dormancy period of the first AP under the plurality of connections is planned to be overlapped with the time indicated by the R-TWT SP information respectively, namely the first AP is dormant under the broadcast connection, so that when the neighbor AP performs low-delay service data transmission under the broadcast connection, the first AP performs communication to cause interference to the low-delay service data transmission of the neighbor AP, the transmission of the low-delay service data is ensured, and the transmission delay of the low-delay service data caused by network congestion is avoided.

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

The first connection and the broadcast connection are STR connection pairs, i.e. service data can be synchronously transmitted and received under the first connection and the broadcast connection. I.e. the traffic data transmission under the first connection does not interfere with the traffic data transmission under the broadcast connection.

Further, in the time indicated by the R-TWT SP information, the service data transmission under the first connection will not interfere with the service data transmission under the broadcast connection, so that the sleep period of the first AP under the first connection can be planned to be non-overlapping with the time indicated by the R-TWT SP information, and the sleep period of the first AP under the first connection can be reasonably planned while the service data transmission in the time indicated by the R-TWT SP information is not interfered.

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

and planning the dormancy period of the first AP under at least one connection to be overlapped with the time indicated by the R-TWT SP information, 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 may monitor the communication record of the neighboring APs by reporting information by STAs associated with the first AP under any of the at least one connection. Specifically, the STA associated with the first AP may report the information to the AP1 when collecting communications of other BSSs (e.g., BSSs where neighboring APs are located; wherein the BSSs are basic service sets, 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 BSSs where neighboring APs are located.

When the first AP monitors the communication record of the neighbor AP, it can be predicted that communication is still possible in the BSS where the neighbor AP is located in the time indicated by the R-TWT SP information, and by planning that the sleep period of the first AP under at least one connection overlaps with the time indicated by the R-TWT SP information, that is, the first AP sleeps under at least one connection in the time indicated by the R-TWT SP information, the communication is still possible in the BSS where the neighbor AP is located. The method can prevent the first AP from communicating to cause interference to communication in the BSS where the neighbor AP is located in the time indicated by the R-TWT SP information. For example, if Link4 is included in at least one connection, 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 Link4 may be scheduled to overlap with the time indicated by the R-TWT SP information.

In the embodiment of the disclosure, a first AP acquires R-TWT SP information of a neighbor AP, and plans a dormancy period of the first AP under at least one connection according to an acquisition mode of the R-TWT SP information; wherein the sleep period overlaps or does not overlap with a time indicated by the R-TWT SP information; in this way, the sleep period of the first AP under different connections can be planned according to different acquisition modes of the R-TWT SP information while not interfering with the transmission of traffic data in the time indicated by the R-TWT SP information. The embodiment of the disclosure provides a mechanism for supporting AP power saving.

Referring to fig. 3, the embodiment of the present disclosure further provides a sleep mechanism negotiation method applied to a neighboring AP, which may include the steps of:

step 301: broadcasting R-TWT SP information of the neighbor AP;

Typically, the APs may include three forms, such as soft AP (or soft AP MLD), NSTR Mobile AP (or NSTR mobile AP MLD; mobile AP; AP MLD Access Point Multi-Link Device, multiple connection access point Device) and regular AP (or regular AP MLD; regular AP), such as a router. Taking soft AP and NSTR mobile AP as examples, battery power is usually used, power consumption is high, and communication with STA is not in long continuous state, so a mechanism for supporting AP power saving needs to be provided. In an embodiment of the present disclosure, taking an example of instructing a first AP to plan a sleep period of the first AP under at least one connection, a mechanism for supporting power saving of the AP is provided.

The first AP may directly acquire the R-TWT SP information broadcast by the neighbor AP by broadcasting the R-TWT SP information of the neighbor AP by the neighbor AP.

In the embodiment of the disclosure, the neighbor AP may further instruct the second AP to share the R-TWT SP information to the first AP by sending the R-TWT SP information to the second AP. Optionally, in the case that the neighbor AP and the first AP cannot monitor each other, the neighbor AP may instruct the second AP to share the R-TWT SP information with the first AP by sending the R-TWT SP information to the second AP, so that the first AP obtains the R-TWT SP information of the neighbor AP. That is, the manner in which the first AP obtains the R-TWT SP information of the neighboring AP may include: receiving R-TWT SP information broadcast by a neighbor AP, receiving R-TWT SP information shared by a second AP by the neighbor AP, and the like.

The at least one connection includes a connection of the first AP with one STA or a connection of the first AP with a plurality of STAs (i.e., the first AP is a multi-connection access point Device (AP MLD)). If the first AP is a multi-connection AP device, the first AP may be independent of each other between sleep periods under each Link. For example, if the at least one connection may include Link1, link2, and Link3, the sleep period of the first AP under Link1 is a period 1, then in this period 1, the first AP is in a sleep state under Link1, and under Link2 or Link3, if the current time is not in the sleep period of Link2 or Link3, the first AP may not sleep, so as to maintain the traffic data transmission.

When the first AP is instructed to plan the sleep period of the first AP under each connection, it may be first determined whether the first AP performs traffic data transmission under the connection, and whether there is a collision with the neighbor AP performing traffic data transmission in the time indicated by the R-TWT SP information, and then, based on whether there is a collision between the two, the first AP is instructed to plan the sleep period of the first AP under the connection. Under the condition that the two do not have conflict, the first AP can be instructed to plan that the dormancy period of the first AP under the connection is not overlapped with the time indicated by the R-TWT SP information, namely, the first AP can perform service data transmission under the connection in the time indicated by the R-TWT SP information, and the neighbor AP can also perform service data transmission. Under the condition that the two conflict, the first AP can be instructed to plan that the dormancy period of the first AP under the connection overlaps with the time indicated by the R-TWT SP information, namely, the first AP can dormancy under the connection in the time indicated by the R-TWT SP information, the neighbor AP can conduct business data transmission, and the phenomenon that the first AP communicates to cause interference to the business data transmission conducted by the neighbor AP when the neighbor AP conducts business data transmission under the connection is avoided. In this way, the first AP can be reasonably instructed to plan the sleep period of the first AP under different connections while not interfering with the transmission of service data in the time indicated by the R-TWT SP information, and a mechanism for supporting the power saving of the AP is provided.

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

the R-TWT SP information indicates the first AP: planning that the dormancy period of the first AP under the broadcast connection overlaps with the time indicated by the R-TWT SP information; wherein the first identification information indicates a range of the applied connection including: broadcast connection of the broadcasted R-TWT SP information;

or (b)

The R-TWT SP information indicates the first AP: planning sleep periods of the first AP under a plurality of connections to overlap with the time indicated by the R-TWT SP information respectively; the first identification information indicates that the range of the applied connection includes a plurality of connections, and the TID information of the broadcast connection indicates that the traffic transmitted by the broadcast connection is low latency traffic.

As an example, the format of the Broadcast TWT Parameter Set (broadcast TWT parameter set) field may be as shown in table 1 above; the format of the request type field in the Broadcast TWT Parameter Set (broadcast TWT parameter set) field may be as shown in table 2 above. For example, the Aligned subfield of the request type field in the Broadcast TWT Parameter Set field may be set to a different value as the first identification information to identify the range of connection to which the R-TWT SP information is applied. Illustratively, when the Aligned subfield is set to a value of 0, identifying that the first identification information indicates a range of connections to which the R-TWT SP information applies includes: broadcast connection of broadcasted R-TWT SP information; when the Aligned subfield is set to a value of 1, the range of connections to which the identification R-TWT SP information is applied includes a plurality of connections.

The format of the limited-target wake-up time transmission information field may be as shown in the foregoing table 3, for example, the Restricted TWT DL TID Bitmap subfield and/or Restricted TWT UL TID Bitmap subfield in the limited-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 the first value, the downlink traffic transmitted by the broadcast connection is indicated as low-latency traffic. When the Restricted TWT UL TID Bitmap subfield is set to the second value, the uplink traffic transmitted by the broadcast connection is indicated as low latency traffic.

In the embodiment of the disclosure, when the first identification information indicates that the range of the connection to which the R-TWT SP information is applied includes the broadcast connection, that is, in the time indicated by the R-TWT SP information, the neighboring AP performs service data transmission under the broadcast connection, by indicating the first AP to plan that the sleep period of the first AP under the broadcast connection overlaps with the time indicated by the R-TWT SP information, that is, the first AP sleeps under the broadcast connection, the first AP performs communication to avoid interference to the service data transmission performed by the neighboring AP when the neighboring AP performs service data transmission under the broadcast connection.

When the first identification information indicates that the range of the connection to which the R-TWT SP information is applied comprises a plurality of connections and the TID information indicates that the service transmitted by the broadcast connection is low-delay service, the first AP is instructed to plan that the dormancy period of the first AP under the plurality of connections is respectively overlapped with the time indicated by the R-TWT SP information, namely the first AP is dormant under the broadcast connection, so that when the neighbor AP transmits low-delay service data under the broadcast connection, the first AP communicates to cause interference to the low-delay service data transmission of the neighbor AP, the transmission of the low-delay service data is ensured, and the transmission delay of the low-delay service data caused by network congestion is avoided.

Optionally, in an embodiment of the disclosure, the R-TWT SP information indicates the first AP: and planning that the dormancy period of the first AP under a first connection is not overlapped with the time indicated by the R-TWT SP information, wherein the first connection and the broadcast connection are STR connection pairs.

Further, in the time indicated by the R-TWT SP information, the service data transmission under the first connection will not interfere with the service data transmission under the broadcast connection, which may indicate the first AP to plan that the sleep period of the first AP under the first connection does not overlap with the time indicated by the R-TWT SP information, so as to reasonably plan the sleep period of the first AP under the first connection while not interfering with the service data transmission in the time indicated by the R-TWT SP information.

Optionally, in an embodiment of the present disclosure, the method may further include the following steps:

and sending the R-TWT SP information to a second AP, and indicating the second AP to share the R-TWT SP information to the first AP.

Alternatively, the neighbor AP may cause the first AP to acquire the R-TWT SP information by directly broadcasting the R-TWT SP information of the neighbor AP. The second AP may also be instructed to forward the R-TWT SP information to the first AP by sending the R-TWT SP information to the second AP, so that the first AP obtains the R-TWT SP information, to ensure that the first AP may obtain the R-TWT SP information. For example, in the case that the first AP and the neighbor AP cannot mutually listen, the first AP may obtain the R-TWT SP information of the neighbor AP by forwarding the R-TWT SP information to the first AP through the neighbor AP.

Alternatively, embodiments of the present disclosure do not limit the order of operations of the neighbor APs themselves to R-TWT SP information, and transmitting R-TWT SP information to the second AP.

By sending the R-TWT SP information to the second AP, the second AP is instructed to share the R-TWT SP information with the first AP, so that the manner in which the first AP obtains the R-TWT SP information of the neighboring AP can be enriched.

In the embodiment of the disclosure, the neighbor AP broadcasts R-TWT SP information of the neighbor AP; the method comprises the steps that R-TWT SP information indicates a first AP to plan a dormancy period of the first AP under at least one connection according to an acquisition mode of 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 may directly obtain the R-TWT SP information of the neighboring AP through broadcasting of the neighboring AP, and plan the sleep period of the first AP under different connections according to different acquisition modes of the R-TWT SP information while not interfering with service data transmission in the time indicated by the R-TWT SP information.

Taking soft AP and NSTR mobile AP as examples, battery power is usually used, power consumption is high, and communication with STA is not in long continuous state, so a mechanism for supporting AP power saving needs to be provided. 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 for supporting power saving of the AP is provided.

Optionally, the second AP may receive the R-TWT SP information sent by the neighboring AP and share the R-TWT SP information with the first AP. Optionally, under the condition that the first AP and the neighbor AP cannot monitor each other, the second AP may forward the received R-TWT SP information of the neighbor AP of the first AP to the first AP, so as to enable the first AP to acquire the R-TWT SP information of the neighbor AP.

Under the condition that the two do not have conflict, the first AP can plan that the dormancy period of the first AP under the connection is not overlapped with the time indicated by the R-TWT SP information, namely, the first AP can be indicated to transmit service data under the connection in the time indicated by the R-TWT SP information, and the neighbor AP can also transmit the service data. Under the condition that the two conflict, the first AP can be instructed to plan that the dormancy period of the first AP under the connection overlaps with the time indicated by the R-TWT SP information, namely, the first AP can dormancy under the connection in the time indicated by the R-TWT SP information, the neighbor AP can conduct business data transmission, and the phenomenon that the first AP communicates to cause interference to the business data transmission conducted by the neighbor AP when the neighbor AP conducts business data transmission under the connection is avoided. In this way, the first AP can be reasonably instructed to plan the sleep period of the first AP under different connections while not interfering with the transmission of service data in the time indicated by the R-TWT SP information, and a mechanism for supporting the power saving of the AP is provided.
