Description

Site wake-up method, device and medium for multi-connected devices

technical field

The present disclosure relates to the field of wireless communication technologies, and in particular, to a method, apparatus and medium for waking up a site of a multi-connected device.

Background technique

In May 2018, the Institute of Electrical and Electronics Engineers (IEEE) established the IEEE 802.11 study group to study IEEE 802.11be as the next-generation mainstream Wi-Fi technology. The research scope includes 320MHz bandwidth transmission and multiple frequency bands. Aggregation and collaboration, etc. Its main application scenarios are video transmission, Augmented Reality (AR), Virtual Reality (VR) and other scenarios. The expected effect of IEEE802.11be is relative to the existing IEEE802.11ax. Increase the transmission rate and data throughput by at least four times, and support low-latency transmission at the same time.

The aggregation and collaboration of multiple frequency bands in IEEE802.11be refers to the simultaneous communication between devices in the frequency bands of 2.4GHz, 5.8GHz and 6-7GHz, so a new Media Access Control (MAC) mechanism needs to be defined to manage the simultaneous communication between devices in multiple frequency bands.

In the existing standard, an access point (Access Point, AP) and a station (Station, STA) establish an initial association under one connection. The hibernation mechanism makes the site hibernate.

In 802.11be, a multi-connection access point device (Access Point Multi-Link Device, AP MLD) includes multiple access points, and a multi-connection station device (Station Multi-Link Device, STA MLD) includes multiple stations. The two are initially associated under one connection, and multiple connections will be activated for subsequent communication. The two can communicate on multiple channels simultaneously through multiple connections.

When multiple connections are established between the AP MLD and the STA MLD, after some of the multiple connections enter the dormant state, when the connection in the dormant state needs to be enabled between the two, the single connection between the access point and the station cannot be used. The wake-up mechanism in the connection context is used to wake up.

Detailed ways

The embodiments of the present disclosure will now be further described with reference to the accompanying drawings and specific embodiments.

Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments are not intended to represent all implementations consistent with embodiments of the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as recited in the appended claims.

The multi-connection between the AP MLD and the STA MLD includes multiple single connections, and each single connection is a one-to-one connection between an AP and an STD.

In an example, as shown in FIG. 1 , the AP MLD includes 4 APs, the STA MLD includes 4 STAs, and 4 connections are established between the AP MLD and the STA MLD.

The four APs included in the AP MLD are: AP1, AP2, AP3, and AP4.

STA MLD includes four STAs: STA1, STA2, STA3, and STA4.

The 4 connections established between AP MLD and STA MLD include:

The first connection, that is, the connection between AP1 and STA1;

The second connection, that is, the connection between AP2 and STA2;

The third connection, that is, the connection between AP3 and STA3;

The fourth connection is the connection between AP4 and STA4.

The process of establishing a connection between an AP and a STA includes: initial association, activation, and successful connection establishment. After the established connection enters the dormant state, the STA corresponding to the connection in the dormant state is in the power saving state. For example, in the multi-connection between AP MLD and STA MLD shown in Figure 1, the connection between AP1 and STA1 is in the awake state, this connection is called the awake connection, and STA1 is in the working state. The connection between AP2 and STA2, the connection between AP3 and STA3, and the connection between AP4 and STA4 are all in the dormant state, these three connections are called dormant connections, and STA2, STA3 and STA4 are all in the power saving state.

In an example, as shown in FIG. 2 , the AP MLD includes 4 APs, the STA MLD includes 5 STAs, and 4 connections are established between the AP MLD and the STA MLD.

The four APs included in the AP MLD are: AP1, AP2, AP3, and AP4.

STA MLD includes five STAs: STA1, STA2, STA3, STA4 and STA5.

The 4 connections established between AP MLD and STA MLD include:

The first connection, that is, the connection between AP1 and STA1;

The second connection, that is, the connection between AP2 and STA2;

The third connection, that is, the connection between AP3 and STA3;

The fourth connection is the connection between AP4 and STA4.

STA5 in the STA MLD has not established a connection with any AP and is in an inactive state.

When multiple connections are established between the AP MLD and the STA MLD, after some of the multiple connections enter the dormant state, when the connection in the dormant state needs to be enabled between the two, the single connection between the access point and the station cannot be used. The wake-up mechanism in the connection scenario is used to wake up, so this disclosure provides a new site wake-up method for multi-connected devices between AP MLD and STA MLD.

An embodiment of the present disclosure provides a method for waking up a site of a multi-connected device, and the method is applied to an AP MLD. Fig. 3 is a flowchart of a method for waking up a station connection according to an exemplary embodiment. As shown in Fig. 3, the method includes:

Step S31, in response to having at least one wake-up connection with the STA MLD, generate a message frame.

Step S32: Send the message frame through the wake-up connection, wherein the message frame includes a wake-up field for waking up at least one STA in the power saving state in the STA MLD.

Among them, the station in the power saving state refers to the STA whose connection state transitions to the dormant state after establishing the connection with the AP in the AP MLD.

In this embodiment, the AP MLD generates a message frame including a wake-up field when a wake-up connection is established with the STA MLD, where the wake-up field is used to wake up at least one STA in the power saving state in the STA MLD. The AP MLD sends a message frame through this wake-up connection to clearly indicate the STA to be woken up to the STA MLD, so that the AP MLD can accurately and effectively control the wake-up of one or at least two stations in the STA MLD, which is the wake-up between the AP MLD and the STA MLD. The mechanism provides new solutions to improve connection management performance.

Those skilled in the art can understand that the current embodiment is that the AP MLD wakes up the STA MLD through the wake-up connection; this is only an example. Those skilled in the art can understand that the foregoing solution can also be that the STA MLD wakes up the AP MLD through the wake-up connection, and the solution is consistent with the idea of the foregoing solution, so it is not repeated here.

An embodiment of the present disclosure provides a method for waking up a site of a multi-connected device, the method includes the method shown in FIG. 1 , and this method can wake up a site in a STA MLD. Wherein, the message frames in steps S31 and S32 are response frames sent during the contention period, and the wake-up field is located in a media access control (MAC) header in the response frame.

In one embodiment, this response frame is a response frame to a power save poll (PS-poll) frame. During the contention period, the STA MLD sends a power saving polling (PS-poll) frame to the AP MLD, and the AP MLD sends a response frame for the power saving polling (PS-poll) frame to the STA MLD, and the response frame carries the wake-up field.

In one embodiment, the wake-up field is a subfield of the control field of the Media Access Control (MAC) frame header. For example: This control domain is the A-control domain.

In one embodiment, the number of bits or bytes occupied by the wake-up field is a set value.

For example, the wake-up field occupies 16 bits, 20 bits, 24 bits or 32 bits, etc.

For example: this wake-up field occupies 1 byte, 2 bytes, 3 bytes or 4 bytes, etc.

In one embodiment, the wake-up field indicates a wake-up manner including one of the following three:

Manner 1 : The wake-up field is a connection set field, the bits of the set position in the wake-up field represent the identification of the site, and the value of the bits of the set position indicates whether to indicate wake-up.

An example is as follows:

The wake-up field occupies 1 byte, and each bit in this 1 byte corresponds to a station in the STA MLD. For example, the first bit corresponds to the first site numbered 1 in the STA MLD, the second bit corresponds to the second site number 2 in the STA MLD, and so on. When the value of a bit is set to "1", it means to wake up the station corresponding to this bit. When the value of a bit is set to "0", it means that the station corresponding to this bit will not be woken up, so that the station will continue to maintain the power saving state.

Taking Figure 1 as an example, among the four stations included in the STA MLD, the number of STA1 is 1, the number of STA2 is 2, the number of STA3 is 3, and the number of STA4 is 4.

There are 4 connections between AP MLD and STA MLD. The connection between STA1 and AP1 is an awake connection, and other connections are in a dormant state. The wake-up field in the message frame occupies 1 byte. The AP MLD sends a message frame to the STA MLD.

When the specific information contained in the wake-up field in the message frame is "01000000", it indicates that the second station, ie STA2, is instructed to wake up.

When the specific information contained in the wake-up field in the message frame is "00100000", it indicates that the third station, that is, STA3, is instructed to wake up.

When the specific information contained in the wake-up field in the message frame is "00010000", it indicates that the fourth station, that is, STA4, is instructed to wake up.

Among them, the first bit is used to indicate STA1, the connection between this STA1 and AP1 is an awake connection, so this bit will not be set to "1".

In a second manner , the wake-up field includes at least one field pair, and each field pair includes a station identification field for indicating a station in a power saving state and/or an indication field for indicating whether to wake up.

Mode 2 includes two implementation modes.

The first implementation method:

When the station identification field in the field pair carries the identification of the station in the power saving state to be woken up, the corresponding indication field carries the wakeup indication;

When the station identification field in the field pair carries the identification of the station in the power saving state that is not awakened, the corresponding indication field carries the non-awakening indication.

The site identifier is an association identifier (Association Identifier, AID) of the site or a MAC address.

An example is as follows:

There are 4 connections between AP MLD and STA MLD. The connection between STA1 and AP1 is an awake connection, and other connections are in a dormant state. The AP MLD sends a message frame to the STA MLD.

The wake-up field included in the message frame includes 3 field pairs, each of which includes a site identification field and an indication field. As shown in Table 1:

Table 1

Wherein, MAC2 represents the address of STA2, MAC3 represents the address of STA3, and MAC4 represents the address of STA4.

The value of the corresponding indication field in the field pair where MAC2 is located is "1", indicating that STA2 is instructed to wake up.

The value of the corresponding indication field in the field pair where MAC3 is located is "0", indicating that STA3 is not to be woken up.

The value of the corresponding indication field in the field pair where the MAC4 is located is "0", indicating that the STA4 is not to be woken up.

The second way to implement:

The site identification field is used to carry the identification of a station in a power saving state that needs to be woken up, and the indication field is used to carry a wakeup indication.

Compared with the example shown in Table 1 in the first implementation, when the second implementation instructs to wake up STA2, the wakeup fields included in the message frame are shown in Table 2:

Table 2

The difference between the second implementation and the first implementation is that the wake-up field in the second implementation only carries the field pair corresponding to the ID of the site in the power-saving state that needs to be woken up, and does not need to carry the field pair that is in the power-saving state that does not wake up. The field pair corresponding to the site ID of the state.

In a third way , the wake-up field includes at least one field pair, and each field pair includes a site identification field and a connection set field.

Mode three includes two implementation modes.

The first implementation method:

The station identification field is used to indicate a station in a power saving state, the bit in the set position in the connection set field represents the identification of the station, and the value of the bit in the set position indicates whether wake-up is indicated.

An example is as follows:

Taking Figure 1 as an example, among the four stations included in the STA MLD, the number of STA1 is 1, the number of STA2 is 2, the number of STA3 is 3, and the number of STA4 is 4. There are 4 connections between AP MLD and STA MLD. The connection between STA1 and AP1 is an awake connection, and other connections are in a dormant state. The AP MLD sends a message frame to the STA MLD.

The wake-up field included in the message frame includes 3 field pairs, and each field pair includes a site identification field and an indication field, as shown in Table 3:

table 3

Wherein, MAC2 represents the address of STA2, MAC3 represents the address of STA3, and MAC4 represents the address of STA4. The MAC address refers to the MAC address of the site under this connection.

The value of the bit corresponding to the position of STA2 in the connection set field corresponding to the field pair where MAC2 is located is "1", indicating that the second STA, ie, STA2, is instructed to wake up.

The value of the bit corresponding to the position of STA3 in the corresponding connection set field in the field pair where MAC3 is located is "0", indicating that the third STA, ie, STA3, is not to be woken up.

The value of the bit corresponding to the position of STA4 in the corresponding connection set field in the field pair where MAC4 is located is "0", indicating that the fourth STA, ie, STA4, is not to be woken up.

The second way to implement:

The station identification field is used to indicate the identification of the station in the power saving state to be woken up, the bit in the set position in the connection set field represents the identification of the station, and the value of the bit in the set position indicates wake-up.

Compared with the example shown in Table 3 in the first implementation, when the second implementation instructs to wake up STA2, the wakeup fields included in the message frame are shown in Table 4:

Table 4

An embodiment of the present disclosure provides a method for waking up a site of a multi-connected device, the method includes the method shown in FIG. 1 , and this method can wake up a site in the STA MLD. Wherein, the message frames in steps S31 and S32 are non-contention polling (CF-poll) frames sent during the non-contention period, and the wake-up field is located in the media access control (MAC) frame of the non-contention polling frame. inside the head. After receiving the non-contention-poll (CF-poll) frame, the STA MLD replies with a response frame for the non-contention-poll (CF-poll) frame.

In one embodiment, the wake-up field is a subfield of the control field of the media access control frame header. For example: This control domain is the A-control domain.

The manner in which the wake-up field indicates wake-up is the same as that in the previous embodiment, which is not repeated here.

An embodiment of the present disclosure provides a method for waking up a station connection, the method includes the method shown in FIG. 1 , and this method can wake up more than one station in the STA MLD.

According to the existing target wake time (Target Wake Time, TWT) mechanism, the station and the access point device negotiate the TWT wake period, and the AP MLD sends a trigger frame within the TWT period. The message frames in steps S31 and S32 are trigger frames sent within the target wake-up time period.

In one embodiment, the wake-up field is located in the trigger-related common information (Trigger Dependent Common Info) field in the trigger frame. The trigger-related public information is a field after the 63rd bit in the trigger frame.

An example is as follows:

The wake-up field occupies 1 byte, and each bit in this 1 byte corresponds to a station in STA MLD. For example, the first bit corresponds to the first site numbered 1 in the STA MLD, the second bit corresponds to the second site number 2 in the STA MLD, and so on. When the value of one bit is set to "1", it means that the site corresponding to this bit is to be woken up. When the value of one bit is set to "0", it means that the site corresponding to this bit is not to be woken up, so that this site will continue to be saved. power status.

When the specific information contained in the wake-up field in the message frame is "01100000", it indicates that the second station, namely, STA2, and the third station, namely, STA3, are instructed to wake up.

When the specific information contained in the wakeup field in the message frame is "00111000", it indicates that the second station, namely STA2, the third station, namely STA3, and the fourth station, namely STA4, are instructed to wake up.

In a second manner , the wake-up field includes a plurality of field pairs, and each field pair includes a station identification field for indicating a station in a power saving state and/or an indication field for indicating whether to wake up.

Mode 2 includes two implementation modes.

The first implementation method:

An example is as follows:

There are 4 connections between AP MLD and STA MLD. The connection between STA1 and AP1 is an awake connection, and other connections are in a dormant state. The AP MLD sends a message frame to the STA MLD to instruct STA2 and STA3 to wake up.

The wake-up field included in the message frame includes 3 field pairs, and each field pair includes a site identification field and an indication field, as shown in Table 5:

table 5

The value of the corresponding indication field in the field pair where MAC3 is located is "1", indicating that the STA3 is instructed to wake up.
