Description

Site awakening method, device and medium for multi-connection equipment

Technical Field

The present disclosure relates to the field of wireless communications technologies, and in particular, to a method, an apparatus, and a medium for waking up a station of a multi-connection device.

Background

In the 5 th month in 2018, the Institute of Electrical and Electronics Engineers (IEEE) established an IEEE802.11 research group for researching IEEE802.11be as the next-generation mainstream Wi-Fi technology, the researched range includes 320MHz bandwidth transmission and aggregation and cooperation of multiple frequency bands, the main application scenarios are video transmission, Augmented Reality (AR), Virtual Reality (VR), and the like, and the expected effect of IEEE802.11be is to improve the transmission rate and data throughput by at least four times compared with the existing IEEE802.11ax and support low-latency transmission at the same time.

The aggregation and cooperation of multiple frequency bands in ieee802.11be means that devices communicate with each other in the frequency bands of 2.4GHz, 5.8GHz, and 6-7GHz, and therefore, a new Media Access Control (MAC) mechanism needs to be defined to manage the communication between the devices in the multiple frequency bands.

In the existing standard, an Access Point (AP) and a Station (STA) establish an initial association under one connection, and in order to save power, the AP and the STA negotiate a sleep period and sleep the Station by using a timely sleep mechanism.

In 802.11be, a Multi-connection Access Point Device (AP MLD) includes multiple Access points, and a Multi-connection Station Device (STA MLD) includes multiple stations. The two carry on the initial association under a connection, and will activate multiple connections for subsequent communication, both can carry on the communication of multiple channels at the same time through the multiple connection.

When a plurality of connections are established between the AP MLD and the STA MLD, and after a part of the plurality of connections enters a sleep state, when the connection in the sleep state needs to be enabled between the AP MLD and the STA MLD, a wake-up mechanism under a single connection scenario of the AP and the STA cannot be used to wake up.

Detailed Description

Embodiments of the disclosure will now be described with reference to the accompanying drawings and detailed description.

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the exemplary embodiments below 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 certain aspects of the present disclosure, as detailed in the appended claims.

The multi-connection between the AP MLD and the STA MLD includes a plurality of single connections, each single connection being a one-to-one connection of one AP and one STD.

In one 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 4 APs included in the AP MLD are: AP1, AP2, AP3, and AP 4.

The STA MLD includes 4 STAs which are: STA1, STA2, STA3, STA 4.

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

a first connection, i.e., a connection between AP1 and STA 1;

a second connection, i.e., between AP2 and STA 2;

a third connection, i.e., between AP3 and STA 3;

the fourth connection, the connection between AP4 and STA 4.

The process of establishing connection between an AP and an STA includes: initial association, activation, and successful connection establishment. After the established connection enters the sleep state, the STA corresponding to the connection in the sleep state is in a power saving state. For example: in the multi-connection between the AP MLD and the STA MLD shown in fig. 1, the connection between the AP1 and the STA1 is in an awake state, which is called an awake connection, and the STA1 is in an operating state. The connection between AP2 and STA2, the connection between AP3 and STA3, and the connection between AP4 and STA4 are all in sleep states, where these 3 connections are called sleep connections, and STA2, STA3, and STA4 are all in power saving states.

In one 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 4 APs included in the AP MLD are: AP1, AP2, AP3, and AP 4.

The STA MLD includes 5 STAs which are: STA1, STA2, STA3, STA4, and STA 5.

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

a first connection, i.e., a connection between AP1 and STA 1;

a second connection, i.e., a connection between AP2 and STA 2;

a third connection, i.e., a connection between AP3 and STA 3;

the fourth connection, the connection between AP4 and STA 4.

STA5 in STA MLD is not connected to any AP and is in an inactive state.

When multiple connections are established between the AP MLD and the STA MLD, and after a part of the connections enter a dormant state, when the connections in the dormant state need to be enabled between the AP MLD and the STA MLD, a wake-up mechanism under a single connection scenario of the AP and the station cannot be used for wake-up, so that the present disclosure provides a new station wake-up method for a multi-connection device between the AP MLD and the STA MLD.

The embodiment of the disclosure provides a site awakening method of a multi-connection device, which is applied to AP MLD. Fig. 3 is a flowchart illustrating a method of waking up a station connection according to an example embodiment, as shown in fig. 3, the method comprising:

Step S31, in response to having at least one awake connection with the STA MLD, generates a message frame.

Step S32, sending the message frame through the wakeup connection, where the message frame includes a wakeup field for waking up at least one STA in a power saving state in the STA MLD.

The station in the power saving state refers to an STA which is in a dormant state after establishing a connection with an AP in the AP MLD.

In this embodiment, the AP MLD generates a message frame including an awake field when an awake connection is established with the STA MLD, where the awake field is used to awake at least one STA in a power saving state in the STA MLD. The AP MLD sends a message frame through the wakeup connection and definitely indicates the STA to be awakened to the STA MLD, so that the AP MLD accurately and effectively controls the awakening of one or at least two stations in the STA MLD, a new solution is provided for an awakening mechanism between the AP MLD and the STA MLD, and the connection management performance is improved.

Those skilled in the art will appreciate that the current embodiment is that the AP MLD wakes up the STA MLD through the wakeup connection; this is by way of example only. It can be understood by those skilled in the art that the foregoing solution may also be that the STA MLD wakes up the AP MLD through the wakeup connection, and the solution is consistent with the idea of the foregoing solution, and therefore, the details are not described herein.

The embodiment of the present disclosure provides a method for waking up a station of a multi-connection device, where the method includes the method shown in fig. 1, and the method can wake up a station in an STA MLD. Wherein the message frames in steps S31 and S32 are response frames transmitted during a contention period, and the wake-up field is located in a Media Access Control (MAC) frame header in the response frames.

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

In one embodiment, the wake-up field is a subfield in the control field of a 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: this wake-up field occupies 16 bits, 20 bits, 24 bits, 32 bits, or the like.

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

In one embodiment, the manner in which the wake field indicates wake includes one of the following three:

In one mode: the wake-up field is a connection set field, and a bit of a set position in the wake-up field indicates the identity of the station, and the value of the bit of the set position indicates whether wake-up is indicated.

Examples are as follows:

the wakeup field occupies 1 byte, and each bit in the 1 byte corresponds to a station in the STA MLD. For example, bit 1 corresponds to the first station numbered 1 in the STA MLD, bit 2 corresponds to the second station numbered 2 in the STA MLD, and so on. Setting the value of a bit to "1" indicates that the station corresponding to the bit is to be woken up. When the value of a bit is set to be "0", it indicates that the station corresponding to the bit is not awakened, so that the station continues to keep the power saving state.

Taking fig. 1 as an example, among 4 stations included in the STA MLD, the STA1 is numbered 1, the STA2 is numbered 2, the STA3 is numbered 3, and the STA4 is numbered 4.

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

When the specific information included in the wake-up field in the message frame is "01000000", it indicates that the 2 nd station, i.e., STA2, is woken up.

When the specific information included in the wakeup field in the message frame is "00100000", this indicates that the 3 rd station, i.e., STA3, is awake.

When the specific information included in the wakeup field in the message frame is "00010000", it indicates that the 4 th station, i.e., STA4, is awake.

The first bit is used to indicate STA1, and the connection between STA1 and AP1 is awake, so this bit is not set to "1".

Mode twoThe wake-up field includes at least one field pair, each of which 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.

The second mode includes two implementations.

The first implementation mode comprises the following steps:

when the station identification field in the field pair carries the identification of the station which needs to be awakened and is in a power saving state, the corresponding indication field carries an awakening indication;

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

The station Identifier is an Association Identifier (AID) of the station or a MAC address.

Examples are as follows:

taking fig. 1 as an example, among 4 stations included in the STA MLD, STA1 is numbered 1, STA2 is numbered 2, STA3 is numbered 3, and STA4 is numbered 4.

4 connections are established between the AP MLD and the STA MLD, the connection between the STA1 and the AP1 is an awakening 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 station identification field and an indication field. As shown in table 1:

TABLE 1

MAC2 indicates the address of STA2, MAC3 indicates the address of STA3, and MAC4 indicates the address of STA 4.

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

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

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

The second implementation mode comprises the following steps:

the station identification field is used for carrying station identification which needs to be awakened and is in a power-saving state, and the indication field is used for carrying awakening indication.

Compared with the example shown in table 1 in the first implementation, when the STA2 is instructed to wake up in the second implementation, the wake-up field included in the message frame is shown in table 2:

TABLE 2

The second implementation manner is different from the first implementation manner in that the wake-up field in the second implementation manner only carries a field pair corresponding to the station identifier in the power saving state that needs to be woken up, and does not need to carry a field pair corresponding to the station identifier in the power saving state that does not need to be woken up.

Mode IIIThe wake-up field includes at least one field pair, each field pair including a site identification field and a connection set field.

The third mode comprises two implementation modes.

The first implementation mode comprises the following steps:

the station identification field is used for indicating stations in a power saving state, a bit of a set position in the connection set field represents an identification of the station, and a value of the bit of the set position represents whether to indicate wakeup.

Examples are as follows:

taking fig. 1 as an example, among 4 stations included in the STA MLD, the STA1 is numbered 1, the STA2 is numbered 2, the STA3 is numbered 3, and the STA4 is numbered 4. 4 connections are established between the AP MLD and the STA MLD, the connection between the STA1 and the AP1 is an awakening 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 field pair including a station identification field and an indication field, as shown in table 3:

TABLE 3

Here, MAC2 indicates the address of STA2, MAC3 indicates the address of STA3, and MAC4 indicates the address of STA 4. Where the MAC address refers to the MAC address of the station under this connection.

The bit in the corresponding connection set field in the pair of fields in which MAC2 is located corresponding to the position of STA2 has a value of "1", indicating that the second STA, STA2, is awake.

The bit in the connection set field corresponding to the position of STA3 in the corresponding pair of fields in which MAC3 is located has a value of "0", indicating that the third STA, i.e., STA3, is not awake.

The bit in the connection set field corresponding to the position of STA4 in the corresponding pair of fields in which MAC4 is located has a value of "0", indicating that the fourth STA, i.e., STA4, is not awake.

The second implementation mode comprises the following steps:

the station identification field is used for indicating the station identification which needs to be awakened and is in a power-saving state, the bit of the set position in the connection set field indicates the station identification, and the value of the bit of the set position indicates the indication of awakening.

Compared to the example shown in table 3 in the first implementation, when the STA2 is awakened in the second implementation, the awakening field included in the message frame is shown in table 4:

TABLE 4

The embodiment of the present disclosure provides a method for waking up a station of a multi-connection device, where the method includes the method shown in fig. 1, and the method may wake up a station in an STA MLD. Wherein the message frames in steps S31 and S32 are non-contention poll (CF-poll) frames transmitted during a non-contention period, and the wake-up field is located in a Medium Access Control (MAC) frame header of the non-contention poll frames. 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 sub-field in the control field of the media access control frame header. For example: this control domain is the a-control domain.

The way of waking up indicated by the wake up field is the same as that in the previous embodiment, and is not described herein again.

The embodiment of the present disclosure provides a method for waking up a station connection, where the method includes the method shown in fig. 1, and the method may wake up more than one station in an STA MLD.

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

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

in a first mode: the wake-up field is a connection set field, and bits of set positions in the wake-up field indicate the identities of the stations, and the values of the bits of the set positions indicate whether wake-up is indicated.

Examples are as follows:

the wakeup field occupies 1 byte, and each bit in the 1 byte corresponds to a station in the STA MLD. For example, bit 1 corresponds to the first station numbered 1 in the STA MLD, bit 2 corresponds to the second station numbered 2 in the STA MLD, and so on. Setting a bit value to be "1" indicates that the station corresponding to the bit is to be awakened, and setting a bit value to be "0" indicates that the station corresponding to the bit is not to be awakened, so that the station is kept in a power-saving state.

When the specific information included in the awake field in the message frame is "01100000", it indicates that the 2 nd station, i.e., STA2, and the 3 rd station, i.e., STA3, are awake.

When the specific information included in the wake-up field in the message frame is "00111000", it indicates that the 2 nd station, i.e., STA2, the 3 rd station, i.e., STA3, and the 4 th station, i.e., STA4 are woken up.

The first bit is used to indicate STA1, and the connection between STA1 and AP1 is awake connection, so this bit is not set to "1".

Mode twoWake-up field packetIncludes a plurality of field pairs, each field pair including a station identification field for indicating a station in a power saving state and/or an indication field for indicating whether to wake up.

The second mode comprises two implementation modes.

The first implementation mode comprises the following steps:

when the station identification field in the field pair carries the identification of the station in the power saving state which is not wakened, the corresponding indication field carries a non-wakening indication.

The station Identifier is an Association Identifier (AID) of the station or a MAC address, where the MAC address refers to a MAC address of the station under a specific connection.

Examples are as follows:

4 connections are established between the AP MLD and the STA MLD, the connection between the STA1 and the AP1 is an awakening connection, and other connections are in a dormant state. The AP MLD sends a message frame to the STA MLD indicating to wake up STA2 and STA 3.

The wake-up field included in the message frame includes 3 field pairs, each field pair including a station 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 STA3 is awake.

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

The second implementation mode comprises the following steps:

the station identification field is used for carrying station identification which needs to be awakened and is in a power-saving state, and the indication field is used for carrying an awakening indication.

Compared to the example shown in table 5 in the first implementation, when the STA2 and STA3 are instructed to wake up in the second implementation, the wake-up field included in the message frame is shown in table 6:

TABLE 6

Mode IIIThe wake-up field includes a plurality of field pairs, each field pair including a site identification field and a connection set field.

The third mode comprises two implementation modes.

The first implementation mode comprises the following steps:

the station identifier field is used for carrying a station identifier in a power saving state, a bit of a set position in the connection set field represents the identifier of the station, and the value of the bit of the set position represents whether to indicate awakening.

Examples are as follows:

The wake-up field included in the message frame includes 3 field pairs, each field pair including a station identification field and an indication field, as shown in table 7:

TABLE 7

Here, MAC2 indicates the address of STA2, MAC3 indicates the address of STA3, and MAC4 indicates the address of STA 4.

The value of the bit corresponding to the STA2 position in the corresponding connection set field in the pair of fields in which MAC2 is located is "1" and the value of the bit corresponding to the STA3 position is "1", indicating that the second STA, STA2, and the third STA, STA3, are awake.

The bit in the corresponding connection set field in the pair of fields in which MAC4 is located corresponding to the position of STA4 has a value of "0", indicating that the fourth STA, STA4, is not awake.

The second implementation mode comprises the following steps:

Compared to the example shown in table 7 in the first implementation, when waking up STA2 and STA3 in the second implementation is indicated, the wake-up field included in the message frame is shown in table 8:

TABLE 8

The embodiment of the present disclosure provides a method for waking up a station connection, where the method includes the method shown in fig. 1, and the method further includes determining at least one station in a power saving state in an STA MLD to be woken up according to at least one of the following parameters:

The number of the basic service sets, the load of the basic service sets and the reference access time delay corresponding to the dormant connection.

The above parameters are known by the AP MLD through rne (reduced Neighbor element) information.
