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 power control method, electronic equipment and a storage medium, which are used for providing an energy saving mechanism in an EMLSR mode.

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, an example in which embodiments of the present disclosure provide a power control method will be described. As shown in fig. 1, AP2, AP3, AP4 are attached to AP MLD; non-AP STA1, non-AP STA2, non-AP STA3, non-AP STA4 are attached to the non-AP MLD. Links between the AP MLD and the non-AP MLD are link 1, link 2, link 3, and link 4, respectively, for example, link 1 between the AP1 and the non-AP STA1, link 2 between the AP2 and the non-AP STA2, link 3 between the AP3 and the non-AP STA3, and link 4 between the AP4 and the non-AP STA 1.

After the non-AP MLD and the AP MLD successfully establish multiple connections, the non-AP MLD can request to enter an EMLSR mode and indicate a link to enable the EMLSR mode, wherein the corresponding link is called an EMLSR mode link; the non-AP STA corresponding to each EMLSR mode link works in an Active state (Active mode) or an Awake state (Awake mode) after entering the EMLSR mode, enters a monitoring operation mode, and can receive an AP MLD to send an initial control frame.

In the embodiment of the disclosure, as shown in fig. 1, taking the case that link 1, link 2, link 3 and link 4 are all in EMLSR mode, the AP MLD sends an initial control frame to the non-AP STA3 (the non-AP STA3 is the first non-AP STA) through the link 3 as an example:

the non-AP MLD responds to the initial control frame received by the non-AP STA3 and sent by the AP MLD, and sends a first message frame to the AP MLD through the link 3 to request to update the power states of the non-AP STAs (other non-AP STAs, i.e., the second non-AP STA) corresponding to other EMLSR mode links that do not receive the initial control frame, and request to update the power states of the non-AP STA1, the non-AP STA2, and the non-AP STA4, so that the other non-AP STAs enter a low power consumption mode, such as a sleep mode.

Optionally, the first message frame may include a first category field, a first session token field, a first information field, and a second information field.

Wherein the first category field identifies that the category of the first message frame is an EMLSR link power mode update request; the first dialogue token field identifies the ID number of the current dialogue; the first information field identifies a link in which each of the second non-AP STAs is located; the second information field identifies a duration corresponding to the low power mode. As an example, the first message frame may be an action frame, and the format of the first message frame may be as shown in table 1 below:

table 1:

optionally, when a bit of the first information field is set to a first parameter value, the second non-AP STA of the link corresponding to the bit is instructed to enter the low power consumption mode in a preset period of time.

The bit of the first information field may be used as a first subfield in the first information field, which may correspond to a link of a second non-AP STA; as an example, the first subfield may be identified by a 2-byte bitmap.

As an example, the format of the first information field may be as shown in the following table 2:

table 2:

information content	EMLSR energy saving bitmap (EMLSR Power Save Bitmap)
		Number of bits	16

When the bit is set to a first parameter value, the second non-AP STA of the link corresponding to the bit may be instructed to enter the low power consumption mode (doze state) in a preset period of time, for example, the first parameter value may be 1. The preset time period may be a data exchange time of the working link. When the bit is set to the second parameter value, it may indicate that the power mode of the second non-AP STA of the link to which the bit corresponds is not updated, for example, the second parameter value may be 0. As an example, for example, the first field is set to 0100010010000101, and the second non-AP STA corresponding to the link 1, the link 3, the link 8, the link 11, and the link 15 enters the low power consumption mode in the preset period.

Optionally, the second information field includes an EMLSR power saving duration (EMLSR PS Duration) subfield; the EMLSR PS Duration subfield identifies the duration of time that the second non-AP STA enters a low power mode.

As an example, the EMLSR PS Duration subfield may have a field length of 3 bits (and may further include 5 bits of reserved bits), and the EMLSR PS Duration subfield may have a format as shown in table 3:

table 3:

as an example, as shown in table 4, the duration of entering the low power mode may be identified by setting the EMLSR PS Duration subfield to different parameters:

table 4:

EMLSR PS Duration subfield value	Corresponding duration of time
		0	2 mus (microsecond)
1	4μs
		2	8μs
3	16μs
		4	32μs
5	64μs
		6	128μs
7	256μs

It should be noted that, the duration corresponding to the low power consumption mode identified by the EMLSR PS Duration subfield is less than or equal to the duration identified by the EMLSR transition delay (EMLSR Transition Delay) field.

After the non-AP MLD transmits the first message frame to the AP MLD, the AP MLD may transmit a second message frame in response, which the non-AP MLD receives.

Optionally, the second message frame includes a second category field, a second session token field, and a status code field. The second category field identifies a category of the second message frame as a response to an EMLSR link power mode update request; the second dialogue token field identifies the ID number of the current dialogue; the status code field identifies whether the AP MLD accepts the EMLSR link power mode update request sent by the non-AP MLD. Wherein the second dialog token field is set to be consistent with the first dialog token field in the first message frame, i.e. the second dialog token field identifies the same session as the first dialog token field.

Alternatively, the AP MLD may be identified by setting the status code field to a third parameter value (for example, the third parameter value may be set to 0 or SUCCESS, etc.), and in this case, the non-AP MLD may allow the corresponding second non-AP STA to enter a low power mode state, where the bit of the corresponding second non-AP STA, that is, the STA corresponding to the link of the first parameter value (for example, 1) is set to the STA corresponding to the link of the first parameter value (for example, 1). For example, if the bit of the first information field corresponding to the link 1 is set to 1, the non-AP STA1 corresponding to the link 1 is allowed to enter the low power mode state.

And switching back to the listening operation (Listening Operation) state after a time period identified by the second information field (EMLSR PS Duration). In this way, the monitoring operation duration of the second non-AP STA can be shortened, namely, the second non-AP STA does not need to monitor during the data exchange of the working link, and the energy consumption of the non-AP MLD is reduced.

In addition, when the status code field is set to a fourth parameter value, the AP MLD is identified to reject the EMLSR link power mode update request sent by the non-AP MLD. In this case, the second non-AP STA maintains the current listening operation state.

In summary, in the embodiment of the present disclosure, in response to the first non-AP STA receiving and responding to the initial control frame sent by the AP MLD, a first message frame is sent to the AP MLD through the working link of the first non-AP STA, and the power states of one or more second non-AP STAs are requested to be updated through the first message frame, so that the energy consumption of the non-AP MLD is reduced.

Referring to fig. 2, the embodiment of the present disclosure provides a power control method, which may alternatively be applied to a multi-connection site device non-AP MLD.

The method may comprise the steps of:

step 201, responding to a first site equipment non-AP STA to receive and respond to an initial control frame sent by a multi-connection access point equipment AP MLD; and sending a first message frame to the AP MLD through an operating link of the first non-AP STA, wherein the first message frame requests to update the power states of one or more second non-AP STAs.

In extremely high-throughput (EHT) communication, throughput may be improved by Multiple Links (ML); among them, a Device having the capability of communicating in parallel over a plurality of links (or a plurality of frequency bands) is called a Multi-Link Device (MLD) Device. The MLD device adopts wider bandwidth to carry out data transmission, so that the throughput rate is greatly improved; the MLD device includes one or more Affiliated (affirmed) stations, which can operate on a link. The MLD device may be an Access Point MLD (AP MLD) or a non-Access Point MLD (Non Access Point Station MLD, non-AP MLD); the corresponding affiliated stations are Access Point (AP) and non-Access Point stations (Non Access Point Station, non AP STA), respectively.

The non-AP MLD may communicate with an AP MLD supporting an EMLSR mode in an enhanced-multilink single radio, EMLSR mode. The EMLSR mode refers to that the non-AP MLD can only communicate with the AP MLD under one link at a time, but can monitor channels under a plurality of links. That is, when the non-AP MLD is in the EMLSR mode, a listening operation may be performed on a channel, and an initial control frame transmitted by the AP MLD is received, wherein the initial control frame is transmitted in an orthogonal frequency division multiplexing PPDU type and a non-high throughput repetition PPDU type.

Specifically, the non-AP MLD in the EMLSR mode receives an initial control frame sent by the AP MLD, and after responding to the initial control frame, a non-AP STA (the non-AP STA belongs to the non-AP MLD) corresponding to a link that receives the initial control frame switches from a listening operation mode to a transmitting/receiving operation mode, and has the capability of transmitting or receiving data on the link that receives the initial control frame. Before the frame exchange on the link receiving the initial control frame is finished, the non-AP STA corresponding to the link of other EMLSR modes is in an active state, but cannot receive or transmit data, so that the energy consumption of the non-AP MLD is caused.

In view of this, embodiments of the present disclosure provide a power saving mechanism that may respond to a first non-AP STA receiving and responding to an initial control frame sent by an AP MLD, send a first message frame to the AP MLD over an active link of the first non-AP STA, and request an update of the power states of one or more second non-AP STAs over the first message frame.

Specifically, the second non-AP STA and the first non-AP STA are attached to the non-AP MLD, the non-AP MLD is in an EMLSR mode, and the first non-AP STA and the second non-AP STA operate in an EMLSR mode link.

The first non-AP STA comprises a non-AP STA which receives an initial control frame, wherein a link for transmitting the initial control frame is a working link of the first non-AP STA, and the working link of the first non-AP STA is an EMLSR mode link. The second non-AP STA comprises a non-AP STA which does not receive the initial control frame, and a link corresponding to the second non-AP STA is an EMLSR mode link.

Alternatively, the power state may include a power state of a low power mode, such as a sleep mode.

For example, in an alternative example, in response to a first non-AP STA receiving and responding to an initial control frame sent by an AP MLD, a first message frame may be sent to the AP MLD over the working link, and the second non-AP STA may be caused to enter a low power mode by requesting an update of the power state of one or more second non-AP STAs over the first message frame. Optionally, after the data exchange of the working link is finished, the second non-AP STA may switch to a listening mode. In this way, the monitoring operation duration of the second non-AP STA can be shortened, namely, the second non-AP STA does not need to monitor during the data exchange of the working link, and the energy consumption of the non-AP MLD is reduced.

Optionally, in an embodiment of the present disclosure, the first message frame includes at least one of the following fields:

a first category field, a first dialog token field, a first information field, and a second information field;

wherein the first category field identifies that the category of the first message frame is an EMLSR link power mode update request;

the first dialogue token field identifies the ID number of the current dialogue;

the first information field identifies a link in which each of the second non-AP STAs is located;

the second information field identifies a duration corresponding to the low power mode.

As an example, the format of the first message frame may be as shown in table 1 above.

Optionally, in an embodiment of the present disclosure, a bit of the first information field is set to a first parameter value, and the second non-AP STA of the link corresponding to the bit is indicated to enter the low power consumption mode in a preset period of time.

Optionally, the bit of the first information field may be used as a first subfield in the first information field, which may correspond to a link of a second non-AP STA; as an example, the first subfield may be identified by a 2-byte bitmap.

As an example, the format of the first information field may be as shown in table 2 above.

Optionally, when the bit is set to the first parameter value, the second non-AP STA of the link corresponding to the bit may be instructed to enter the low power consumption mode (doze state) within a preset period of time, for example, the first parameter value may be 1. The preset time period may be a data exchange time of the working link. When the bit is set to the second parameter value, it may indicate that the power mode of the second non-AP STA of the link to which the bit corresponds is not updated, for example, the second parameter value may be 0. As an example, for example, the first field is set to 0100010010000101, and the second non-AP STA corresponding to the link 1, the link 3, the link 8, the link 11, and the link 15 may enter the low power consumption mode during the preset period.

Optionally, in an embodiment of the present disclosure, a duration corresponding to the low power consumption mode identified by the second information field is less than or equal to a duration identified by an EMLSR transition delay (EMLSR Transition Delay) field.

As an example, the EMLSR PS Duration subfield may have a field length of 3 bits (and may further include 5 bits reserved bits), and the EMLSR PS Duration subfield may have a format as shown in table 3 above.

As an example, as shown in table 4 above, the duration of entering the low power mode may be identified by setting the EMLSR PS Duration subfield to different parameters.

The embodiment of the disclosure provides a power control method, which can be optionally applied to multi-connection site equipment non-AP MLD.

The method may comprise the steps of:

responding to the initial control frame sent by the multi-connection access point equipment (AP) MLD received by the first site equipment non-AP STA; and sending a first message frame to the AP MLD through an operating link of the first non-AP STA, wherein the first message frame requests to update the power states of one or more second non-AP STAs.

After the transmitting the first message frame to the AP MLD, the method further includes:

receiving a second message frame sent by the AP MLD;

the second message frame comprises at least one of the following fields:

a second category field, a second dialog token field, and a status code field;

wherein the second category field identifies a category of the second message frame as a response to an EMLSR link power mode update request;

the second dialogue token field identifies the ID number of the current dialogue;

the status code field identifies whether the AP MLD accepts the EMLSR link power mode update request sent by the non-AP MLD.

Alternatively, after transmitting the first message frame to the AP MLD, the AP MLD may transmit a second message frame in response, which the non-AP MLD receives.

Wherein the second dialog token field is set to be consistent with the first dialog token field in the first message frame, i.e. the second dialog token field identifies the same session as the first dialog token field.

Optionally, in an embodiment of the disclosure, the method further includes:

the status code field is set to a third parameter value, allowing the second non-AP STA of the link for which the bit of the first information field is set to the first parameter value to enter a low power mode state; and after the duration of the second information field identifier, the second non-AP STA is switched into a monitoring operation state; wherein, the third parameter value identifies that the AP MLD accepts the EMLSR link power mode update request sent by the non-AP MLD;

or (b)

And the status code field is set to a fourth parameter value, and the identification of the AP MLD refuses the EMLSR link power mode update request sent by the non-AP MLD.

Alternatively, the AP MLD may be identified by setting the status code field to a third parameter value (for example, the third parameter value may be set to 0 or SUCCESS, etc.), and in this case, the non-AP MLD may allow the corresponding second non-AP STA to enter a low power mode state, where the bit of the corresponding second non-AP STA, that is, the STA corresponding to the link of the first parameter value (for example, 1) is set to the STA corresponding to the link of the first parameter value (for example, 1). And switching back to the listening operation (Listening Operation) state after a time period identified by the second information field (EMLSR PS Duration). In this way, the monitoring operation duration of the second non-AP STA can be shortened, namely, the second non-AP STA does not need to monitor during the data exchange of the working link, and the energy consumption of the non-AP MLD is reduced.

The method may comprise the steps of:

Optionally, the first message frame includes at least one of the following fields:

Optionally, the bit of the first information field is set to a first parameter value, and the second non-AP STA of the link corresponding to the bit is instructed to enter the low power consumption mode in a preset time period.

or (b)

In an embodiment of the disclosure, a power saving mechanism is provided, where a non-AP MLD responds to an initial control frame received by a first non-AP STA and sent by the AP MLD, and sends a first message frame to the AP MLD through an operating link of the first non-AP STA, and requests updating of power states of one or more second non-AP STAs through the first message frame.

The AP MLD receives the first message frame.

For example, in an alternative example, a non-AP MLD may send a first message frame to an AP MLD over the working link in response to a first non-AP STA receiving and responding to an initial control frame sent by the AP MLD, and request an update of the power state of one or more second non-AP STAs through the first message frame, causing the second non-AP STAs to enter a low power mode. Optionally, after the data exchange of the working link is finished, the second non-AP STA may switch to a listening mode. In this way, the monitoring operation duration of the second non-AP STA can be shortened, namely, the second non-AP STA does not need to monitor during the data exchange of the working link, and the energy consumption of the non-AP MLD is reduced.

In summary, in the embodiment of the present disclosure, the non-AP MLD responds to the initial control frame received by the first non-AP STA and sent by the AP MLD, and sends the first message frame to the AP MLD through the working link of the first non-AP STA, and requests to update the power states of one or more second non-AP STAs through the first message frame, thereby reducing the energy consumption of the non-AP MLD.
