Technical field

The present application relates to the field of communication technology, and in particular, to a communication method and device.

Background technique

Many wireless devices (especially terminal devices) are battery-powered, so energy-saving features are particularly important. The standard protocol IEEE 802.11ah introduces target wakeup time (TWT) technology in the Internet of Things (IoT) field. The TWT request site can be maintained outside the TWT service period (TWT SP). Hibernate to reduce energy consumption.

The standard protocol IEEE 802.11ax extends TWT to the broadband field. In one case, the non-access point station (non-access point station, non-AP STA) can negotiate the TWT SP with the access point (access point, AP), which is called unicast TWT (individual TWT). In another case, the AP can carry one or more broadcast TWT (broadcast TWT) identifiers in frames such as beacon frames through scheduling. Each broadcast TWT corresponds to one or more broadcast TWT service phases (broadcast TWT). SP), non-AP STA can apply to join one or more broadcast TWT (broadcast TWT), so that it can maintain energy saving at times other than the joined broadcast TWT SP.

In order to save more energy, IEEE 802.11ax introduces a TWT information frame (TWT information frame), which can be used to pause unicast TWT or broadcast TWT. In this way, after the TWT requesting STA (TWT requesting STA) and the TWT scheduled STA (TWT scheduled STA) exchange TWT information frames, they can enter the sleep mode before the TWT resumes, which is beneficial to energy saving.

At present, more and more wireless network applications and services have put forward strict requirements on delay characteristics, such as online games, virtual reality, industrial sites, etc. To this end, the next-generation wireless local area network (WLAN) IEEE 802.11be standard regards ensuring delay and delay jitter characteristics as a key technical goal, and has received widespread attention from the industry. Based on this, IEEE 802.11be proposed restricted target wakeup time (r-TWT) technology to improve delay guarantee performance. r-TWT technology is a mechanism derived from the broadcast TWT introduced by IEEE 802.11ax to ensure low-latency services.

However, the current TWT information frame cannot flexibly indicate the above multiple types of TWT when instructing to suspend TWT, which may affect service performance.

The communication method provided by this application can be applied to data communication between an AP and one or more STAs, to communications between APs, and to communications between STAs. There are no restrictions on this application.

Some technologies involved in the embodiments of this application are briefly introduced below.

1. Next generation wireless local area network (WLAN) standard

WLAN has experienced standards such as IEEE 802.11a/b/g/n/ac/ax, and the 802.11be currently under discussion, and its standard version continues to evolve and develop. Among them, the name of the 802.11n standard can also be called high throughput (HT), the 802.11ac standard can also be called very high throughput (VHT), and the 802.11ax can also be called high efficient (HE). 802.11be can also be called extremely high throughput (EHT), while standards before HT, such as 802.11a/b/g, can be collectively called non-HT.

2. Target wakeup time (TWT)

Many wireless devices (especially terminal devices) are battery-powered, so energy-saving features are particularly important. IEEE802.11ah first introduced the concept of TWT in the IoT field. A TWT requesting STA (TWT requesting STA) can negotiate the TWT service period (TWT service period, TWT SP, or SP for short) with another TWT responding STA (TWT responding STA), so that the TWT requesting STA can be maintained at a time other than the TWT SP. Sleep to save energy.

IEEE 802.11ax extends TWT to the broadband field. Non-access point stations (non-AP STA) can negotiate TWT SPs with APs, which is called unicast TWT (individual TWT). A unicast TWT can be uniquely determined based on the TWT requesting STA's media access control (MAC) address and a TWT flow identifier.

In addition, IEEE 802.11ax also allows APs (called TWT scheduling APs) to carry one or more broadcast TWTs in frames such as beacon frames through scheduling. Each broadcast TWT (broadcast TWT) Corresponding to one or more broadcast TWT service phases (broadcast TWT SP), non-AP STA (called TWT scheduled STA) can apply to join one or more Broadcast TWT, thus maintaining power saving at times other than the joined Broadcast TWT SP. The broadcast TWT can be uniquely determined based on the MAC address of the TWT scheduling AP and a broadcast TWT ID.

3. Restricted target wakeup time (r-TWT)

At present, more and more wireless network applications and services have put forward strict requirements on delay characteristics, such as online games, virtual reality, industrial sites, etc. To this end, the next-generation WLAN IEEE 802.11be standard regards ensuring delay and delay jitter characteristics as a key technical goal, which has received widespread attention from the industry. IEEE 802.11be plans to introduce r-TWT technology to improve delay guarantee performance.

As shown in Figure 3, the r-TWT mechanism is a new mechanism to ensure low-latency services derived from the broadcast TWT introduced by IEEE 802.11ax. Under the 802.11be standard, non-AP EHT STA (hereinafter referred to as EHT STA) has many real-time applications (RTA), and the traffic of these applications has very strict latency requirements (stringent latency requirements). Based on this, a r-TWT mechanism.

When the EHT STA in the basic service set (BSS) receives any r-TWT SP information broadcast by the AP, if the r-TWT option implementation (dot11RestrictedTWTOptionImplemented) of the EHT STA is set to true (true) , then the EHT STA must end its transmission opportunity (TXOP) before the r-TWT SP start time. In addition, the AP can set a quiet interval (quiet interval) aligned with the r-TWT SP start time in the beacon frame (beacon) or response (probe response) frame, and the duration can be 1 millisecond (ms). The length of the silent interval is generally shorter than the length of r-TWT SP. The EHT STAs belonging to this r-TWT SP group (grouped by broadcasting TWT ID) are called r-TWT scheduled STAs (r-TWT scheduled STAs). It is stipulated that the r-TWT scheduled STAs can ignore the above silent interval, and then in r -TWT competes for the channel after SP starts. Other legacy stations (legacy STAs) and other EHT STAs need to remain silent according to the silent interval. This will reduce the number of STAs competing for the channel in the BSS and increase the probability of EHT STAs with low-latency services competing for the channel. Among them, traditional sites can refer to STAs that do not support IEEE 802.11be and support IEEE 802.11ax.

Currently, IEEE 802.11ax introduces a TWT Information frame, which can be used to suspend unicast TWT or broadcast TWT. The frame format of the TWT information frame can be shown in Table 1 below, in which the format of the TWT Information field (TWT Information field) can be shown in Figure 4.

Table 1 Frame format of TWT information frame

Among them, the TWT flow identifier (TWT flow identifier) field is used to indicate the identity of the unicast TWT. Response requested is fixed to 0 in IEEE 802.11ax. A value of 1 in the next TWT request field indicates that the peer is required to send a TWT information frame containing a "next TWT" field with a length that is not 0. The next TWT subfield size is used to indicate the length of the next TWT (next TWT) field in this TWT information field. A value of 1 in the "All TWT" field indicates that this TWT information frame indicates all TWTs, and a value of 0 indicates that this TWT information frame does not indicate all TWTs. The next TWT (next TWT) field is used to indicate the TWT pause time.

After the TWT requesting STA and the TWT scheduled STA interact through the TWT information frame, the TWT requesting STA and the TWT scheduled STA can enter the sleep mode before the TWT is restored, which is beneficial to energy saving.

In the above introduction of the TWT information frame, to use the TWT information frame to pause the broadcast of TWT, you must set "all The value of the TWT" field is 1. One of the broadcast TWTs cannot be paused through the TWT information frame. This is because the broadcast TWT ID field does not exist in the frame structure of the TWT information field. Therefore, the TWT information Frame support for broadcasting TWT is very limited.

Moreover, when the value of the "all TWT" field is 1, not only all unicast TWTs are suspended, but all broadcast TWTs are also suspended. This means that the TWT information frame cannot distinguish between pausing all unicast TWTs, pausing all broadcast TWTs, or pausing all unicast TWTs and all broadcast TWTs. It should be pointed out that unicast TWT and broadcast TWT are different in function and use.

Furthermore, r-TWT is a special broadcast TWT introduced by IEEE 802.11be to ensure the delay characteristics of low-latency services. Although r-TWT reuses broadcast TWT from frame structure to interaction mode, its technical goals and STA processing methods are significantly different from broadcast TWT in IEEE 802.11ax. However, if the value of the "all TWT" field is 1, then not only all unicast TWTs are suspended, all broadcast TWTs supported by IEEE 802.11ax are also suspended, and all r-TWTs are also suspended. Among them, r-TWT is aimed at low-latency characteristics, and general broadcast TWT is often aimed at energy saving. For example, in order to further improve the energy saving effect, the AP can send TWT information frames to make the STA sleep for a longer period of time (no need to wake up during this TWT pause time), but the r-TWT used for low latency is the same. Also canceled.

On the other hand, r-TWT is a pre-reserved resource for low latency, so it is possible that the AP has completed the transmission of low-latency services through random competition before the arrival of the r-TWT SP. Therefore, the originally planned r- TWT SP is no longer needed. Therefore, the AP only needs to pause all r-TWTs at this time, but does not need to pause other unicast TWTs or broadcast TWTs. However, the above suspension method can only suspend all these types of TWT, and does not take into account the particularity of r-TWT.

It can be seen from the above that the current TWT information frame cannot flexibly indicate the suspension of multiple types of TWT, which may affect service performance.

Based on this, embodiments of the present application propose a communication method to flexibly indicate the suspension of multiple types of TWT and improve service performance.

The various methods proposed in this application for flexibly indicating the suspension of multiple types of TWT will be described in detail below through specific embodiments.

Figure 5 shows a schematic flowchart of a communication method provided by an embodiment of the present application. In the communication method shown in Figure 5, when all TWT fields are set to 1, whether the r-TWT is paused can be indicated through the first field in the first frame, thereby clearly indicating the suspension of the r-TWT. By way of example, the process of this method may include:

Step 501: The first device determines the first frame. The first frame includes a first field. When all TWT fields are set to 1, the first field is used to indicate whether the r-TWT is suspended. Wherein, the r-TWT may represent at least one r-TWT or all r-TWT.

It should be noted that the fields involved in this application can also be described as information fields, subfields, cells, information fields, domains, elements, etc. This application does not limit this.

Optionally, the first frame may be a unicast frame.

When the All TWT field is set to 1, that is, when all TWTs are indicated, the first field may indicate whether r-TWT is paused. Alternatively, it may also be understood that the first field may indicate when all TWTs need to be paused. , whether the r-TWT is paused.

It should be noted that the "all" in "all TWT" in this application may include all TWT of at least one type. The "all TWT" field may be used to indicate that at least one type of TWT is to be uniformly suspended. ” may not contain all or all types of TWT.

In this application, the "All TWT" field can be the 8th bit (B7) in the TWT information field shown in Figure 4 in the above introduction. This bit can be named All TWT, which is a possibility for the All TWT field. The implementation can be All TWT fields. It should be understood that all TWT fields in this application can also have other names, such as Conditional All TWT (Conditional All TWT) or other names in the future, etc., and this application does not limit this.

In an optional implementation, when all TWT fields are set to 1, the first field is used to indicate whether r-TWT is suspended: the all TWT fields are set to 1, the first field The value of a field is a first value, and the first field indicates that the r-TWT is suspended; the all TWT fields are set to 1, the value of the first field is a second value, and the first field Instruct the r-TWT not to pause.

Exemplarily, the first field may include 1 bit, and the all TWT fields are set to 1. When the value of the 1 bit is the first value, the first field indicates that the r-TWT is paused; The all TWT fields are set to 1, and when the value of the 1 bit is the second value, the first field indicates that the r-TWT is not paused. Wherein, the first field including 1 bit can also be understood as the length of the first field being 1 bit.

Optionally, the first value is 1 and the second value is 0; or, the first value is 0 and the second value is 1.

In an example, the first field may be an r-TWT indication field included, and the r-TWT indication field included may also be called an r-TWT indication field (r-TWT Included). Furthermore, when all TWT fields are set to 1, the first field is used to indicate whether r-TWT is suspended, which may have the following meaning: all TWT fields are set to 1, and the first field indicates that the r-TWT needs to be suspended. The TWT includes the r-TWT; or, the all TWT fields are set to 1, and the first field indicates that the TWT that needs to be suspended does not include the r-TWT.

Wherein, the first field indicates that the TWTs that need to be suspended include the r-TWT. It can be understood that the first field is used to indicate that the r-TWT is suspended. The first field indicates that the TWTs that need to be suspended do not include the r-TWT. It can be understood that the first field is used to indicate that the r-TWT is not suspended. Optionally, the TWTs that need to be suspended in this application can be all TWTs.

Since r-TWT is a special broadcast TWT, when all TWT fields are set to 1, the first field indicates that the TWTs that need to be paused include the r-TWT, which can also be understood as the first information indicating that the The suspended broadcast TWT (which may be all broadcast TWTs) includes the r-TWT, which means that all broadcast TWTs including the r-TWT need to be suspended at this time.

Similarly, when the All TWT field is set to 1, the first field indicates that the TWT that needs to be paused does not include the r-TWT. It can also be understood that the first information indicates that the broadcast TWT that needs to be paused does not include the r-TWT. r-TWT, that is to say, all other broadcast TWTs except the r-TWT need to be suspended at this time.

For example, taking the first field including 1 bit as an example, when the first field includes an r-TWT indication field, an example of a value description including the r-TWT indication field may be as shown in Table 2 below.

Table 2 includes the value description of the r-TWT indicator field

It should be noted that in Table 2, only the value "0" for the indication field containing r-TWT indicates that the paused broadcast TWT does not include r-TWT, and the value "1" indicates that the paused broadcast TWT includes r-TWT. Example explanation. It should be understood that the value of the r-TWT indication field may also be "1" to indicate that the paused broadcast TWT does not include r-TWT, and the value of "0" indicates that the paused broadcast TWT includes r-TWT. This application does not cover this. limited.

In yet another example, the first field may be an exclude r-TWT indication field, which is an exclude r-TWT indication field. It may also be called an excluded r-TWT indication domain (r-TWT excluded). Furthermore, when all TWT fields are set to 1, the first field is used to indicate whether r-TWT is suspended, which may have the following meaning: when all TWT fields are set to 1, the first field indicates that it is not required. The r-TWT is excluded from the suspended TWT; or, the all TWT fields are set to 1, and the first field indicates that the r-TWT is excluded from the TWT that needs to be suspended.

Wherein, the first field indicates that the r-TWT is not excluded from the TWTs that need to be suspended, which can be understood as the first field indicating that the r-TWT is suspended. The first field indicates that the r-TWT is excluded from the TWTs that need to be paused, which can be understood as the first field indicating that the r-TWT is not paused.

Since r-TWT is a special broadcast TWT, when the all TWT fields are set to 1, the first field indicates that the r-TWT is not excluded from the TWT that needs to be paused, which can also be understood as the first The information indicates not to exclude the r-TWT from the broadcast TWTs that need to be suspended (which may be all broadcast TWTs). That is to say, all broadcast TWTs including the r-TWT need to be suspended at this time.

Similarly, when the all TWT fields are set to 1, the first field indicates that the r-TWT is excluded from the TWT that needs to be paused. It can also be understood that the first information indicates that the r-TWT is excluded from the broadcast TWT that needs to be paused. The r-TWT, that is to say, all other broadcast TWTs except the r-TWT need to be suspended at this time.

For example, taking the first field including 1 bit as an example, when the first field is the excluded r-TWT indication field, an example of the value description of the excluded r-TWT indication field may be as shown in Table 3 below.

Table 3 Value description of excluded r-TWT indication domain

It should be noted that in Table 3, only the value of the exclude r-TWT indication field is "0" to indicate that r-TWT is not excluded from the suspended broadcast TWT, and the value of "1" indicates that the r-TWT is not excluded from the suspended broadcast TWT. Exclusion in TWT is explained as an example. It should be understood that the value of the exclude r-TWT indication field can also be "1" to indicate that the r-TWT is not excluded from the suspended broadcast TWT, and the value of "0" indicates that the r-TWT is excluded from the suspended broadcast TWT. There are no restrictions on this application.

In a possible implementation manner, the first field can reuse the existing fields (or existing fields) of the TWT information frame of IEEE 802.11ax as shown in Figure 4. For example, as shown in Figure 6, the TWT information frame of IEEE 802.11ax stipulates that when all TWT values in the TWT information field are 1, the 3-bit TWT flow identification field is reserved (Reserved). Based on this, in the embodiment of the present application, the first field can multiplex 1 bit in the 3-bit TWT stream identification field. That is, as shown in Figure 6, when all TWT values are 1, the 3-bit One bit of the TWT stream identification field is used as the first field, and the other two bits are still reserved (Reserved).

It should be noted that the position of the bits multiplexed in the first field is not limited to the last bit in the 3-bit TWT stream identification field shown in Figure 6. It should be understood that it can also be the first bit or the middle bit. This application does not limit this.

It should be noted that FIG. 6 only shows an exemplary schematic diagram of the structure of the first frame. It should be understood that the structure of the first frame can also be implemented in various other ways, which is not limited in this application.

It can be understood that in the frame structure shown in Figure 6, when all TWT values are 0, the bits multiplexed in the first field can still have the original meaning, and no longer indicate the meaning indicated by the first field. The application does not limit the functions of the bits multiplexed in the first field. Of course, from one perspective, it can also be understood that when all TWT values are 0, there is no first field.

In an optional implementation, the first frame may also include a second field, and the second field may be used to Indicates a suspended TWT type, where the TWT type may include at least one of unicast TWT, broadcast TWT, unicast TWT and broadcast TWT, or r-TWT.

The second field may be a TWT type indication field, or may be called a TWT type indication field (TWT type indication).

Optionally, the second field may include 2 bits, or may be described as having a length of 2 bits. The second field may indicate different types of suspended TWT by taking different values of the 2 bits. .

For example, assuming that the second field is the TWT type indication field and the second field includes 2 bits, an example of the value description of the TWT type indication field can be shown in Table 4 below.

Table 4 Value description of TWT type indication field

It should be noted that the correspondence between the values and meanings of the TWT type indication field in Table 4 is only an example, and the correspondence between different values and different meanings is not limited in this application. For example, a value of 0 may correspond to indicating a pause in broadcasting TWT, etc.

Following the example of Table 4, taking the first field as an example including the r-TWT indication field, the joint description of the TWT type indication field and the value of the r-TWT indication field may be as shown in Table 5 below.

Table 5 Joint description of TWT type indication field and values including r-TWT indication field

It should be noted that the unicast TWT mentioned in Table 4 and Table 5 can be all unicast TWT, the broadcast TWT can be all broadcast TWT, and the r-TWT can be all r-TWT.

As can be seen from Table 5, when all TWT fields are set to 1, when the TWT type indication field indicates that the type of the suspended TWT is broadcast TWT, or the type is unicast TWT and broadcast TWT, different values of the first field can be Indicates whether r-TWT is paused. In the above two cases, the value description of the first field can be found in the above table. 2 and related descriptions in Table 3.

However, when the TWT type indication field indicates that the type of the suspended TWT is unicast TWT or the type is r-TWT, the value of the first field may be any value, such as 0, 1 or a reserved value. That is to say, when all the TWT fields are set to 1, when the TWT type indication field indicates that the type of the suspended TWT is unicast TWT, no matter what the value of the first field is, it can be understood as indicating that the r-TWT is not suspended. . When the all TWT fields are set to 1, and when the TWT type indication field indicates that the type of the suspended TWT is r-TWT, no matter what the value of the first field is, it can be understood as indicating r-TWT suspension.

It should be noted that when the TWT type indication field indicates that the type of TWT to be suspended is unicast TWT, or the type is r-TWT, the first field may not exist, that is, the suspension can be clearly indicated only through the TWT type indication field. The type of TWT, and then clarify whether r-TWT is paused. In this case, the bits occupied by the first field can also be used as fields indicating other functions, which is not limited in this application.

In an optional implementation, the above-mentioned TWT type indication field and the first field can be combined into one field, and this field can still be represented by the first field. At this time, the first field can also be used to indicate a pause. TWT type. At this time, the first field may include 3 bits, and different values of the 3 bits may correspond to different indications in Table 4.

Optionally, the name of the field that combines the above-mentioned TWT type indication field and the first field may also be called suspended TWT indication (suspended TWT indication), etc. This application does not limit this.

In an optional implementation, when the first frame contains the first field and the second field, the first field and the second field can multiplex the existing TWT information frame of IEEE 802.11ax as shown in Figure 4. There are fields. For example, as shown in Figure 7, the TWT information frame of IEEE 802.11ax stipulates that when all TWT values are 1, the 3-bit TWT stream identification field becomes reserved (Reserved). Based on this, in the embodiment of the present application, the first field can multiplex 1 bit in the 3-bit TWT stream identification field, and the second field can multiplex 2 bits in the 3-bit TWT stream identification field. . That is, as shown in Figure 7, when all TWT values are 1, 1 bit of the 3-bit TWT stream identification field is used as the first field, and the other 2 bits are used as the second field.

It should be noted that the position of the bits multiplexed between the first field and the second information bit is not limited to the position in the 3-bit TWT stream identification field shown in Figure 7, and this application does not limit this.

It should be noted that FIG. 7 only shows a schematic diagram of the structure of an exemplary first frame. It should be understood that when the first frame includes a first field and a second field, the structure of the first frame may also have many other structures. implementation manner, this application does not limit this.

Optionally, when the first field and the second field are combined into one field, for example, when the combined field is the first field, the first field can multiplex 3 bits in the TWT stream identification field shown in Figure 7, This is not shown in detail here.

It can be understood that in the frame structure shown in Figure 7, when all TWT values are 0, the bits multiplexed in the first field and the second field can still have the original meaning, and no longer indicate the first field and The second field indicates the meaning. This application does not limit the functions of the bits multiplexed in the first field and the second field. Of course, from one perspective, it can also be understood that when all TWT values are 0, the first field and the second field do not exist.

Step 502: The first device sends the first frame to the second device, and accordingly, the second device receives the first frame from the first device.

Wherein, the first device may be a TWT Scheduling AP (TWT Scheduling AP) or a TWT scheduling site (TWT scheduled STA), and the second device may be a TWT scheduled site.

Step 503: The second device determines whether the r-TWT is suspended according to the first frame.

Exemplarily, the second device may determine the r-TWT based on the specific indication of the field in the first frame in step 501. Whether to pause, please refer to the relevant description in step 501 for details.

Based on the above communication method, when all TWT fields are set to 1, the first field in the first frame can be used to indicate whether the r-TWT is suspended, thereby clearly indicating the suspension of the r-TWT, thereby improving service performance.

Figure 8 shows a schematic flowchart of another communication method provided by an embodiment of the present application. In the communication method shown in FIG. 8 , the type of TWT that needs to be paused can be indicated through the third field in the first frame, thereby clarifying the TWT that needs to be paused. By way of example, the process of this method may include:

In a first optional implementation, the third field may include 2 bits. Different values of the third field may indicate at least one of the following: suspension of all unicast TWTs, suspension of all broadcast TWTs, suspension of all unicast TWTs and all broadcast TWTs, or suspension of all r-TWTs. At this time, the function of the third field can refer to the function of the second field in the embodiment shown in FIG. 5 . For example, the description of different values of the third field can be seen in Table 4 above.

In this first optional implementation, the first frame may further include a fourth field when the third field is used to indicate the suspension of all broadcast TWTs, or when the third field is used to When indicating the suspension of all unicast and all broadcast TWTs, the fourth field is used to indicate whether all the suspended broadcast TWTs include all r-TWTs. It can also be understood that the fourth field is used to indicate whether all r-TWTs are pause.

Optionally, when the All TWT field is set to 1, when the third field is used to indicate the suspension of all broadcast TWTs, or when the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs When , the fourth field is used to indicate whether all broadcast TWTs that are suspended include all r-TWTs, that is, the fourth field is used to indicate whether all r-TWTs are suspended.

Exemplarily, when the All TWT field is set to 1, when the third field is used to indicate the suspension of all broadcast TWTs, or when the third field is used to indicate all unicast TWTs and all broadcast TWTs When paused, the fourth field is used to indicate whether all r-TWTs are paused, which can be implemented in the following manner: the all TWT fields are set to 1, and when the third field is used to indicate the pause of all broadcast TWTs, Alternatively, when the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs, the value of the fourth field is the first value, and the fourth field indicates the suspension of all r-TWTs; The All TWT field is set to 1 when the third field is used to indicate the suspension of all broadcast TWTs, or when the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs, the fourth The value of the field is the second value, and the fourth field indicates that all r-TWTs are not suspended.

The fourth field may include 1 bit, and the All TWT field is set to 1 when the third field is used to indicate the suspension of all broadcast TWTs, or when the third field is used to indicate the suspension of all unicast When TWT and all broadcast TWTs are paused, the value of the 1 bit is the first value, and the fourth field indicates that all r-TWTs are paused; the all TWT fields are set to 1, and when the third field is When indicating the suspension of all broadcast TWTs, or when the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs, the value of the 1 bit is the second value, and the fourth field Instructs all r-TWT not to pause. Wherein, the fourth field including 1 bit can also be understood to mean that the length of the fourth field is 1 bit.

Optionally, the first value is 1 and the second value is 0; or, the first value is 0 and the second value is 1.

In an example, the fourth field includes an r-TWT indication field. Furthermore, when the All TWT field is set to 1, when the third field is used to indicate the suspension of all broadcast TWTs, or when the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs When, the fourth field is used to indicate whether all r-TWTs are suspended, which may have the following meaning: the all TWT fields are set to 1, when the third field is used to indicate the suspension of all broadcast TWTs, or when When the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs, the fourth field indicates that all broadcast TWTs suspended include all r-TWTs; or, the all TWT field is set to 1, when the When the third field is used to indicate the suspension of all broadcast TWTs, or when the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs, the fourth field indicates that the suspended all broadcast TWTs do not include All r-TWT. In this case, the fourth field may have the same function as the first field in the embodiment shown in FIG. 5 when it includes the r-TWT indication field. For details, please refer to the above Table 2, which will not be described in detail here.

In another example, the fourth field may be an r-TWT exclusion indication field. Furthermore, when the All TWT field is set to 1, when the third field is used to indicate the suspension of all broadcast TWTs, or when the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs When, the fourth field is used to indicate whether all r-TWTs are suspended, which may have the following meaning: the all TWT fields are set to 1, when the third field is used to indicate the suspension of all broadcast TWTs, or when When the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs, the fourth field indicates not to exclude all r-TWTs from the suspended all broadcast TWTs; or, the all TWT field is set to 1 , when the third field is used to indicate the suspension of all broadcast TWTs, or when the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs, the fourth field indicates the suspension of all broadcast TWTs. Exclude all r-TWTs from the broadcast TWT. In this case, the fourth field may have the same function as the first field in the embodiment shown in FIG. 5 when it is the packet exclusion r-TWT indication field. For details, please refer to the above Table 3, which will not be described in detail here.

When the four fields are included in the first frame, but the third field indicates the suspension of all unicast TWTs, or when the third field indicates the suspension of all r-TWTs, the value of the fourth field The value and meaning may not be limited, that is, the fourth field may be 0, 1 or any other reserved value.

Based on the above, when the third field and the fourth field are included in the first frame, taking the fourth field as including the r-TWT indication field as an example, the third field and the fourth field The joint description of the field values can be found in Table 5 above, and will not be described in detail here.

In the above-mentioned first optional implementation manner, the structure of the first frame may still be as shown in FIG. 7 . At this time, when all TWT values are 1, the fourth field can multiplex 1 bit in the 3-bit TWT stream identification field, and the third field can multiplex 1 bit in the 3-bit TWT stream identification field. 2 bits. That is, the fourth field refers to the above-mentioned first field, and the third field refers to the above-mentioned second field. For details, please refer to the relevant descriptions in the above embodiments, which will not be described in detail here.

In a second optional implementation, the third field may include 3 bits. Different values of the third field can be used to indicate at least one of the following: the suspension of one unicast TWT, the suspension of all unicast TWTs, the suspension of one broadcast TWT, the suspension of all broadcast TWTs, the suspension of all unicast TWTs and a pause for all broadcast TWTs or a pause for all r-TWTs.

Optionally, the third field is used to indicate the suspension of all broadcast TWTs, which may include the following two situations: the third field is used to indicate the suspension of broadcast TWTs in all broadcast TWTs except all r-TWTs; or , the third field is used to indicate the suspension of all broadcast TWTs including all r-TWTs.

Optionally, the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs, which may include the following two situations: the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs except all - Pause of broadcast TWTs other than TWT; alternatively, the third field is used to indicate the suspension of all unicast TWTs and all broadcast TWTs including all r-TWTs.

For example, in this second optional implementation, the value description of the third field may be as shown in Table 6 below.

Table 6 Value description of the third field

It should be noted that the correspondence between the values and meanings of the third field in Table 6 is only an example, and the correspondence between different values and different meanings is not limited in this application. For example, a value of 0 may correspond to indicating a pause of a single broadcast TWT, etc.

In this second optional implementation, the structure of the first frame can be implemented in a variety of ways. For example, when the third field indicates the suspension of a unicast TWT, the structure of the first frame may be as shown in Figure 9, where the third field in Figure 9 is a TWT type indication. Domain is shown as an example. For another example, when the third field indicates a pause of broadcasting TWT, the structure of the first frame may be as shown in Figure 10, where the third field in Figure 10 is a TWT type indication. Domain is shown as an example.

Optionally, the first frame is a unicast frame.

Step 802: The first device sends the first frame to the second device, and accordingly, the second device receives the first frame from the first device.

Wherein, the first device may be a TWT Scheduling AP (TWT Scheduling AP) or a TWT scheduling site (TWT scheduled STA), and the second device may be a TWT scheduled site.

Step 803: The second device suspends the TWT indicated by the third field.

For example, the second device may determine the type of TWT to be paused based on the specific indication of the field in the first frame in step 801, and then perform corresponding pause. For details, please refer to the relevant description in step 801.

Based on the above communication method, the type of TWT that needs to be paused can be flexibly indicated through the third field in the first frame, thereby clarifying the TWT that needs to be paused.

It should be noted that the above only takes the example that the first device can be a TWT Scheduling AP (TWT Scheduling AP) or a TWT scheduling site (TWT scheduled STA), and the second device can be a TWT scheduled site. OK, detailed introduction. Optionally, the first device may be a TWT scheduled site, and the second device may be a TWT scheduling AP (TWT Scheduling AP) or a TWT scheduled STA. In this case, the first device determines the One frame (for the first frame, please refer to the description in the embodiments shown in Figures 5 to 8 above), after sending the second frame to the second device, the second device returns a confirmation frame to the first device, and then the second device After receiving the acknowledgment frame, a device performs a corresponding TWT pause operation based on the first frame (specifically similar to the operation performed by the second device based on the first frame, and may be referred to each other), which will not be described in detail here.

Optionally, in the embodiment of this application, the TWT scheduling AP (TWT Scheduling AP) or the TWT scheduling site (TWT scheduled STA) may be the R-TWT scheduling AP (R-TWT Scheduling AP) or the R-TWT scheduling STA (R- TWT Scheduling STA), the TWT scheduled site can be an R-TWT scheduled site (R-TWT scheduled STA). In this application, R-TWT scheduling AP may refer to an EHT AP that supports R-TWT. R-TWT scheduled STA may refer to a non- broadcast TWT element that supports R-TWT and is sent to or received from the R-TWT AP and carries the R-TWT parameter set (R-TWT Parameter Set). AP EHT STA.

In some embodiments, in order to improve the efficiency of suspending TWT of multiple STAs, embodiments of the present application also provide a communication method. Referring to Figure 11, the process of the method may include:

Step 1101: The access point determines a broadcast frame, where the broadcast frame includes a fifth field, and the fifth field is used to determine the target station that needs to suspend the target TWT.

The broadcast frame is a frame whose destination address is a broadcast address.

Wherein, the target site may be at least one site.

Step 1102: The access point sends the broadcast frame, and corresponding multiple stations receive the broadcast frame.

It should be noted that FIG. 11 only takes the first station receiving the broadcast frame as an example. It should be understood that the operations of other stations can refer to the related operations of the first station.

Step 1103: The first site determines whether the first site is included in the target site according to the fifth field.

For example, when the first site determines that it is included in the target site, the first site suspends the corresponding TWT; when the first site determines that it is not included in the target site, the first site A station may ignore the broadcast frame.

Optionally, the fifth field may be used to indicate at least one broadcast TWT that needs to be paused. Furthermore, the first site determines whether the first site is included in the target site based on the fifth field. The method may include the following two methods:

Method 1: The first field indicates the identity of at least one broadcast TWT that needs to be paused. The first station can determine whether the first station is included in the target station according to the identity of the at least one broadcast TWT.

Exemplarily, when the first site determines whether the first site is included in the target site according to the identification of the at least one broadcast TWT, the method may be: the first site determines that it has joined the at least one broadcast. when the first site determines that the identification of the at least one broadcast TWT is not added, the first site may determine that the first site is included in the target site. It is determined that the first site is not included in the target site.

Method 2: The first field indicates to suspend all broadcast TWTs, and the first station determines that the first station is included in the target station.

In a first optional implementation, the fifth field may include a TWT identification field and an all TWT field, and the all TWT field is used to indicate whether to suspend all TWTs. All TWT fields with a value of 0 indicate no temporary Stop all TWT, a value of 1 indicates to suspend all TWT. Furthermore, the first site may determine whether the first site is included in the target site according to the TWT identification field and all TWT fields in the fifth field.

Optionally, the TWT identification field and the all TWT field may jointly indicate to suspend at least one broadcast TWT or indicate to suspend all broadcast TWTs. For example, the All TWT field used to indicate not to suspend all TWTs may include indicating to suspend at least one broadcast TWT. The All TWT field used to indicate suspending all TWTs may include indicating suspending all broadcast TWTs.

Specifically, when the value of the All TWT field is 0, that is, when the All TWT field indicates that all TWTs are not to be suspended, and the first station has joined the broadcast TWT indicated by the TWT identification field, the first station determines The first site is included in the target site; or, when the value of all TWT fields is 0, that is, when the all TWT fields indicate that all TWTs are not suspended, and the first site does not join the TWT identification field indication When broadcasting TWT, the first station determines that the first station is not included in the target station. For example, in combination with the above method 1, the TWT identification field may indicate the identification of at least one broadcast TWT indicating that it needs to be suspended. If the first station has joined the broadcast TWT indicated by the TWT identification field, it means that the first station The at least one broadcast identifier has been added. If the first station does not join the broadcast TWT indicated by the TWT identification field, it means that the first station does not join the at least one broadcast identification.

Alternatively, when the value of the All TWT field is 1, that is, the All TWT field indicates that all TWTs are suspended, the first station determines that the first station is included in the target station. For example, in conjunction with the above method 2, if the All TWT field indicates that suspending all TWTs may include suspending all broadcast TWTs, then the first station determines that the first station is included in the target station.

In a second optional implementation, the fifth field may include at least one TWT pause parameter set, and each of the TWT pause parameter sets includes a TWT identification field and all TWT fields. Furthermore, the first site determines whether the first site is included in the target site according to the fifth field.

Similarly, optionally, the TWT identification field and the all TWT field in each TWT suspension parameter set may jointly indicate to suspend at least one broadcast TWT or indicate to suspend all broadcast TWTs. For example, the All TWT field used to indicate not to suspend all TWTs may include indicating to suspend at least one broadcast TWT. The All TWT field used to indicate suspending all TWTs may include indicating suspending all broadcast TWTs.

Specifically, when all TWT fields in the first TWT suspension parameter set in the at least one TWT suspension parameter set indicate not to suspend all TWTs, and the first station has joined the TWT identification field indication in the first TWT suspension parameter set, When broadcasting TWT, the first station determines that the first station is included in the target station. Or, when all TWT fields in the first TWT suspension parameter set indicate not to suspend all TWTs, and the first station does not join the broadcast TWT indicated by the TWT identification field in the first TWT suspension parameter set, the first station A site determines that the first site is not included in the target site. For example, in combination with the above method 1, the TWT identification field in the first TWT suspension parameter set may indicate the identification of at least one broadcast TWT indicating that it needs to be suspended, and the first station has joined the broadcast TWT indicated by the TWT identification field. , it means that the first station has added the at least one broadcast identifier. If the first station does not join the broadcast TWT indicated by the TWT identification field, it means that the first station does not join the at least one broadcast identification.

Alternatively, when all TWT fields in the first TWT suspension parameter set indicate that all TWTs are suspended, the first station determines that the first station is included in the target station. For example, in combination with the above second method, the All TWT field in the first TWT suspension parameter set indicates that suspending all TWTs may include the need to suspend all broadcast TWTs, then the first station determines that the first station is included in the target site.

For example, the first site can perform comparison in the at least one TWT pause parameter set in sequence. When all TWT values in a TWT pause parameter set are 0, if the first site has joined When this one TWT pauses the broadcast TWT indicated by the TWT identification field in the parameter set, the first station determines that it is included in the target station. In the case where all TWT values in a TWT pause parameter set are 0, if the first station does not join the broadcast TWT indicated by the TWT identification field in the TWT pause parameter set, the first station ignores the TWT Pause parameter set, continue to compare the next TWT pause parameter set, if compared to the last TWT pause parameter set, all TWT values in the last TWT pause parameter set are 0, if the first site has not joined the If a TWT pauses the broadcast TWT indicated by the TWT identification field in the parameter set, the first station determines that it is not included in the target station. When all TWT values in a TWT pause parameter set are 1, the first station determines that it is included in the target station.

Optionally, in this second optional implementation, the fifth field can also be encapsulated in an element (element), or the fifth field can be understood as an element. The broadcast frame may be a management frame such as a Beacon frame or a Probe Response frame. For example, the frame structure of this element may be as shown in Figure 12.

The structure of each TWT pause parameter can be any frame structure in the embodiment shown in Figure 5 or Figure 8, and will not be described again here.

In a third optional implementation, the fifth field is used to determine the target site that needs to suspend TWT. Specifically, the fifth field may directly indicate the target site that needs to suspend TWT.

For example, the fifth field may indicate the target site by indicating the identification of the target site that needs to suspend TWT. Optionally, the identification of the target site may exist in the form of a list or the like.

For example, taking the identification of the target station as a list, in the third optional implementation, the broadcast frame can multiplex the TWT information frame in IEEE 802.11ax, as shown in Table 7 shows that compared to the current frame structure of the TWT information frame in Table 1, an association identification list element (AID List Element) is added, that is, the association identification list element is the fifth field. The association identification list element is used to indicate the target STAs of this TWT information frame (for example, it can be indicated by the bitmap of the AID). The structure of the association identification list elements is not limited in this application.

Table 7 Structure of broadcast frame

The above method of adding an association identification list element to the frame structure of a TWT information frame can keep the meaning of the original TWT information frame unchanged and only enhance its functions without involving a new frame.

Optionally, the association identification list element may not be used as a new element of the TWT information frame, but as part of the TWT information field in the TWT information frame, that is, an association identification list field (also called association) is added to the TWT information field. Identification list field (AID List field), that is, adding a fifth field. In this way, compared to the method in Table 7, there is no need to design new elements, but only enhanced functions in existing elements.

For example, when an association identification list field can be added to the TWT information field, the broadcast frame can also include a sixth field, and the sixth field is used to indicate whether the fifth field exists. For example, the sixth field may be included in the TWT information field. The sixth field may include one bit, by which one bit differs Takes a value to indicate whether the fifth field exists.

Furthermore, the broadcast frame may also indicate the TWT information that needs to be suspended, that is, the TWT information that indicates that the target station needs to be suspended. When the first site determines that the first site is included in the target site, the first site may pause the TWT according to the TWT information that needs to be paused.

Optionally, the broadcast frame may be implemented in multiple ways to indicate the TWT information that needs to be paused. For example, the indication method of the TWT information field in IEEE 802.be can be used, or any indication method in the embodiment shown in Figure 5 can be used, or any one of the embodiments shown in Figure 8 can be used As the indication method, any indication method in the embodiment shown in Figure 11 can also be used, and this application is not limited to this.

In one example, in the above second optional implementation, the broadcast frame may indicate the TWT that the target station needs to suspend through each TWT suspension parameter set. Furthermore, when the first station determines that it is included in the target station, the first station may pause all broadcast TWTs according to the information in the first TWT pause parameter set.

In yet another example, in the above third optional implementation, when the first station determines that it is included in the target station, the first station may determine the target station based on the content of the TWT information field of the broadcast frame. Pause the corresponding TWT.

It should be understood that in addition to the above examples, there are also many ways, which will not be listed here.

Based on the above communication method, the efficiency of suspending TWT of multiple STAs can be improved by indicating the target station through broadcast frames.

Based on the above embodiments, embodiments of the present application also provide a communication device. Referring to FIG. 13, the communication device 1300 may include a processing unit 1301. The processing unit 1301 is used to control and manage the actions of the communication device 1300. . Optionally, the communication device 1300 may also include a transceiver unit 1302.

Figure 15 shows a schematic flowchart of another communication method provided by an embodiment of the present application. In the communication method shown in FIG. 15 , the type of TWT that needs to be paused can be indicated through the seventh field in the first frame, thereby clarifying the TWT that needs to be paused. By way of example, the process of this method may include:

Step 1501: The first device determines a first frame. The first frame includes a seventh field. The seventh field may be used to indicate one of the following: suspension of all TWTs, suspension of all TWTs except R-TWT. Pause of TWT or pause of all R-TWT.

Among them, all TWTs include all unicast TWTs and all broadcast TWTs including R-TWT; TWTs other than R-TWT among all TWTs include all unicast TWTs and all broadcast TWTs except R-TWT.

Optionally, the broadcast TWT in this application can also be replaced by a multicast TWT (groupcast TWT).

It should be understood that the seventh field may respectively indicate at least one of the above multiple types of TWT suspensions through different values.

In an optional implementation, the seventh field may include 2 or 3 bits. Different values of the seventh field may indicate at least one of the following: suspension of all TWTs, suspension of all TWTs except R-TWT, or suspension of all R-TWTs.

For example, taking the seventh field including 2 bits as an example, the value description of the seventh field can be as shown in Table 8 below:

Table 8 Value description of the seventh field

It should be noted that the correspondence between the values and meanings of the seventh field in Table 8 is only an example, and the correspondence between different values and different meanings is not limited in this application. For example, a value of 0 may correspond to indicating the suspension of all TWTs except the R-TWT.

In an optional implementation, when the first frame includes the seventh field, the seventh field may reuse existing fields of the TWT information frame of IEEE 802.11ax as shown in Figure 4.

For example, as shown in Figure 16, the TWT information frame of IEEE 802.11ax stipulates that when all TWT values are 1, the 3-bit TWT flow identification field becomes reserved (Reserved). Based on this, in this embodiment of the present application, the seventh field may multiplex 2 or 3 bits of the 3-bit TWT stream identification field. For example, as shown in the schematic diagram of Figure 16, when all TWT values are 1, the last 2 bits of the 3-bit TWT stream identification field are used as the seventh field, and the other bits are still reserved (Reserved).

It should be noted that the position of the bits multiplexed in the seventh field is not limited to the positions of the last two bits in the 3-bit TWT stream identification field shown in Figure 16, and this application does not limit this.

It should be noted that FIG. 16 only shows an exemplary schematic diagram of the structure of the first frame. It should be understood that the structure of the first frame can also be implemented in various other ways, which is not limited in this application.

It can be understood that in the frame structure shown in Figure 16, when all TWT values are 0, the bits multiplexed in the seventh field can still have the original meaning, and no longer indicate the meaning indicated by the seventh field. The application does not limit the function of the bits multiplexed in the seventh field. Of course, from one perspective, it can also be understood that when all TWT values are 0, there is no seventh field. That is, in this application, when all TWT fields have a value of 1, the seventh field is used to indicate the suspension of different types of TWT, and the meaning and operation when all TWT fields have a value of 0 do not change.

Optionally, the name of the seventh field can be All R-TWT (All R-TWT), All R-TWT excluded (All R-TWT excluded), TWT type subfield or other names, which is not limited in this application.

Optionally, the first frame may be a unicast frame.

Step 1502: The first device sends the first frame to the second device, and accordingly, the second device receives the first frame from the first device.

Wherein, the first device may be an R-TWT scheduling AP (R-TWT scheduling AP), and the second device may be an R-TWT scheduled site (R-TWT scheduled STA).

In this application, R-TWT scheduling AP may refer to an EHT AP that supports R-TWT. R-TWT scheduled STA may refer to a non- broadcast TWT element that supports R-TWT and is sent to or received from the R-TWT AP and carries the R-TWT parameter set (R-TWT Parameter Set). AP EHT STA.

Step 1503: The second device suspends the TWT indicated by the seventh field.

For example, the second device may determine the type of TWT to be paused based on the specific indication of the field in the first frame in step 1501, and then perform corresponding pause. For details, please refer to the relevant description in step 1501.

In this embodiment, all TWTs except R-TWT are regarded as one type of TWT, that is, corresponding to All TWT before the introduction of R-TWT, and R-TWT is regarded as another type of TWT, which can be flexibly adjusted through the instructions in the seventh field. Implementation of suspending one of the categories Or two types of TWT, which maintain flexibility and are consistent with existing technologies in classification.

It should be noted that in this application, R-TWT and r-TWT are the abbreviations of the same noun restricted target wakeup time. No distinction is made in this embodiment, and the entire text of this application applies.

Based on the above communication method, the type of TWT that needs to be paused can be flexibly indicated through the seventh field in the first frame, thereby clarifying the TWT that needs to be paused.

Figure 17 shows a schematic flowchart of another communication method provided by an embodiment of the present application. In the communication method shown in FIG. 17 , the type of TWT that needs to be paused can be indicated through the eighth field in the first frame, thereby clarifying the TWT that needs to be paused. By way of example, the process of this method may include:

Step 1701: The first device determines a first frame. The first frame includes an eighth field. The eighth field may be used to indicate one of the following: suspension of all TWTs, suspension of all TWTs except R-TWT. Pause of TWT or pause of all R-TWT.

Specifically, the eighth field is similar to the seventh field involved in the embodiment shown in FIG. 15. Please refer to the description of the seventh field in the above step 1501, which will not be described in detail here.

Step 1702: The first device sends the first frame to the second device, and accordingly, the second device receives the first frame from the first device.

Among them, the first device can be an R-TWT scheduled site (R-TWT scheduled STA), and the second device can be an R-TWT scheduling AP (R-TWT Scheduling AP).

Step 1703: The second device sends an acknowledgment frame to the first device, and accordingly, the first device receives the acknowledgment frame from the second device.

Step 1704: The first device suspends the TWT indicated by the eighth field.

For example, after receiving the acknowledgment frame, the first device can determine the type of TWT to be paused based on the specific indication of the field in the first frame in step 1701, and then perform a corresponding pause. For details, please refer to the relevant description in step 1701. .

In this embodiment, all TWTs except R-TWT are regarded as one type of TWT, that is, corresponding to All TWT before the introduction of R-TWT, and R-TWT is regarded as another type of TWT, which can be flexibly adjusted through the indication of the eighth field. Implementing the suspension of one or two types of TWT not only maintains flexibility, but also remains consistent with existing technologies in terms of classification.

Based on the above communication method, the type of TWT that needs to be paused can be flexibly indicated through the eighth field in the first frame, thereby clarifying the TWT that needs to be paused.

In addition, in a possible implementation, a TWT teardown frame can be introduced to tear down a TWT agreement (TWT agreement) or all TWT agreements. The frame format of the TWT teardown frame can be shown in Table 9 below.

Table 9 Frame format of TWT teardown frame

Among them, the Category field is used to indicate that the action frame is an Unprotected S1G Action frame. The Unprotected S1G Action field is used to indicate that the frame is a TWT Teardown frame. The format of the TWT Flow field can be shown in Figures 18 and 19. Figure 18 is the frame structure when the Negotiation Type field is set to 0 or 1, that is, the frame structure for unicast TWT. Figure 19 is the frame structure when the Negotiation Type field is set to 3, which is for Broadcast The frame structure of broadcast TWT.

When a STA wants to tear down a unicast TWT, the STA will send a TWT teardown frame, set the TWT Flow Identifier field to the ID of the unicast TWT, and set the Negotiation Type field to 0.

When a STA wants to tear down a broadcast TWT, the STA will send a TWT teardown frame, set the Broadcast TWT ID field to the ID of the broadcast TWT, and set the Negotiation Type field to 3.

When a STA wants to tear down all TWTs, the STA will send a TWT teardown frame and set the Teardown All TWT (Teardown All TWT) field to 1. When the Teardown All TWT field is set to 1, the TWT Flow Identifier, Broadcast TWT ID and Negotiation Type fields are reserved fields.

When R-TWT is introduced, when the Teardown All TWT field is set to 1, all TWTs including R-TWT will be dismantled. This cannot dismantle only the R-TWT, or only other TWTs except the R-TWT, and the disassembly flexibility is poor.

Based on this, embodiments of the present application also provide another communication method to realize the removal of multiple types of TWT and improve service performance.

The various methods proposed in this application for flexibly instructing the disassembly of various types of TWTs are described in detail below through specific embodiments.

Figure 20 shows a schematic flowchart of a communication method provided by an embodiment of the present application. In the communication method shown in Figure 20, when all TWT teardown fields are set to 1, the ninth field in the first frame can be used to indicate whether the R-TWT is torn down, thereby clearly indicating the teardown of the R-TWT. By way of example, the process of this method may include:

Step 2001: The first device determines the first frame. The first frame includes a ninth field. When all TWT fields are removed and set to 1, the ninth field is used to indicate whether the R-TWT is removed. Wherein, the R-TWT may represent at least one R-TWT or all R-TWT.

Among them, the "Teardown All TWT" field can be the 8th bit (B7) in the TWT Flow field as shown in Figure 18 or Figure 19. This bit can be named Teardown All TWT, which is one possibility of tearing down all TWT fields. The implementation can be Teardown All TWT field. It should be understood that the removal of all TWT fields in this application can also have other names, and this application does not limit this.

In an optional implementation, when the Remove All TWT field is set to 1, the ninth field is used to indicate whether the R-TWT is removed: the Remove All TWT field is set to 1, so The value of the ninth field is a first value, and the ninth field indicates that all R-TWTs are not to be removed; the removal of all TWT fields is set to 1, the value of the ninth field is a second value, and the value of the ninth field is a second value. Nine fields indicate all R-TWT removal.

Exemplarily, the ninth field may include 1 or more bits, the remove all TWT field is set to 1, and when the 1 or more bits take the value of the first value, the ninth field indicates all R -TWT is not torn down; the teardown of all TWT fields is set to 1, and when the value of the 1 or more bits is the second value, the ninth field indicates the teardown of all R-TWTs. Wherein, the ninth field including 1 or more bits can also be understood as the length of the ninth field being 1 bit.

Optionally, when the ninth field includes multiple bits, there may be reserved bits among the multiple bits.

Optionally, the first value is 1 and the second value is 0; or, the first value is 0 and the second value is 1.

For example, assuming that the ninth field includes 1 bit, the value description of the ninth field may be as described in Table 10 below.

Table 10 Value description of the ninth field

It should be noted that Table 10 only takes the ninth field as an example with a value of “0” indicating that all R-TWTs are not to be dismantled, and a value of “1” indicating that all R-TWTs are dismantled. It should be understood that the value of the ninth field can also be "1" to indicate that the R-TWT is not removed, and the value of "0" indicates that the R-TWT is removed. This application does not limit this.

Optionally, when the ninth field includes multiple bits, the functions in the above Table 10 may be implemented by one bit among the multiple bits, and other bits except the one bit may be reserved.

Exemplarily, the ninth field can reuse the existing fields in the TWT Flow field shown in Figure 18 and Figure 19. For example, when the Remove All TWT field in the TWT Flow field is set to 1, the first 7 bits (B0-B6) of the TWT Flow field are reserved (Reserved). Based on this, in this application, the ninth field can multiplex one or more bits among the 7 bits. For example, when one bit is multiplexed as the ninth field, the other 6 bits are still reserved. This application does not limit the reuse method and location.

Optionally, the name of the ninth field can be All R-TWT (All R-TWT), All R-TWT excluded (All R-TWT excluded), TWT Type (TWT Type) subfield or other names. There are no restrictions on application.

Optionally, the first frame may be a unicast frame.

Step 2002: The first device sends the first frame to a second device, and accordingly, the second device receives the first frame from the first device.

Wherein, the first device may be an R-TWT scheduling AP (R-TWT scheduling AP), and the second device may be an R-TWT scheduled site (R-TWT scheduled STA).

Step 2003: The second device determines whether the R-TWT is torn down according to the first frame.

For example, the second device may determine whether the R-TWT is to be removed based on the specific indication of the field in the first frame in step 2001. For details, please refer to the relevant description in step 2001.

Based on the above communication method, when all TWT removal fields are set to 1, the ninth field in the first frame can be used to indicate whether the R-TWT is to be removed, thereby clearly indicating the removal of the R-TWT, thereby improving service performance.

Figure 21 shows a schematic flowchart of another communication method provided by an embodiment of the present application. In the communication method shown in Figure 21, when all TWT removal fields are set to 1, the tenth field in the first frame can be used to indicate whether the R-TWT is to be removed, thereby clearly indicating the removal of the R-TWT. By way of example, the process of this method may include:

Step 2101: The first device determines the first frame. The first frame includes a tenth field. When all TWT fields are removed and set to 1, the tenth field is used to indicate whether the R-TWT is removed. Wherein, the R-TWT may represent at least one R-TWT or all R-TWT.

Specifically, the tenth field is similar to the ninth field involved in the embodiment shown in FIG. 20. Please refer to the description of the ninth field in the above step 2001, which will not be described in detail here.

Step 2102: The first device sends the first frame to the second device, and accordingly, the second device receives the first frame from the first device.

Among them, the first device can be an R-TWT scheduled site (R-TWT scheduled STA), and the second device can be an R-TWT scheduling AP (R-TWT Scheduling AP).

Step 2103: The second device sends an acknowledgment frame to the first device, and accordingly, the first device receives the acknowledgment frame from the second device.

Step 2104: The first device determines whether the R-TWT is torn down according to the first frame.

For example, the first device may determine whether the R-TWT is to be removed based on the specific indication of the field in the first frame in step 2101. For details, please refer to the relevant description in step 2101.

Based on the above communication method, when all TWT removal fields are set to 1, the tenth field in the first frame can be used to indicate whether the R-TWT is to be removed, thereby clearly indicating the removal of the R-TWT, thereby improving service performance.

Figure 22 shows a schematic flowchart of another communication method provided by an embodiment of the present application. In the communication method shown in Figure 22, the type of TWT to be removed can be indicated through the eleventh field in the first frame, thereby clarifying the TWT that needs to be removed. By way of example, the process of this method may include:

Step 2201: The first device determines the first frame. The first frame includes an eleventh field. The eleventh field can be used to indicate one of the following: removal of all TWTs, removal of all TWTs except R-TWT. Removal of external TWT or removal of all R-TWT.

Among them, all TWTs include all unicast TWTs and all broadcast TWTs including R-TWT; TWTs other than R-TWT among all TWTs include all unicast TWTs and all broadcast TWTs except R-TWT.

It should be understood that the eleventh field may indicate at least one of the above multiple types of TWT disassembly through different values.

In an optional implementation, the eleventh field may include 2 or more bits. Different values of the eleventh field may indicate at least one of the following: removal of all TWTs, removal of all TWTs except R-TWTs, or removal of all R-TWTs. Wherein, when the eleventh field includes more than two bits, there may be reserved bits among the multiple bits.

For example, taking the eleventh field including 2 bits as an example, the value description of the eleventh field can be as shown in Table 11 below:

Table 11 Value description of the eleventh field

It should be noted that the correspondence between the values and meanings of the eleventh field in Table 11 is only an example, and the correspondence between different values and different meanings is not limited in this application. For example, a value of 0 may be taken to indicate the teardown of all TWTs except the R-TWT.

Exemplarily, the eleventh field can reuse the existing fields in the TWT Flow field shown in Figure 18 and Figure 19. For example, when the Remove All TWT field in the TWT Flow field is set to 1, the first 7 bits (B0-B6) of the TWT Flow field are reserved (Reserved). Based on this, in this application, the eleventh field can multiplex 2 or more bits among the 7 bits. For example, when 2 bits are multiplexed as the eleventh field, the other 5 bits are still reserved. This application does not limit the reuse method and location.

It can be understood that in the frame structure shown in Figure 18 or Figure 19, when all TWT values are removed and are 0, the bits multiplexed in the eleventh field can still have the original meaning and no longer indicate the eleventh field. The meaning of the field indication, this application does not limit the function of the bits multiplexed in the eleventh field. Of course, from one perspective, it can also be understood that when all TWT values are removed and the value is 0, there is no eleventh field. That is to say, in this application, when the value of the Remove All TWT field is 1, the eleventh field is used to indicate the removal of different types of TWT. The meaning of when the value of the Remove All TWT field is 0 and operations are unchanged.

Optionally, the name of the eleventh field can be All R-TWT (All R-TWT), All R-TWT excluded (All R-TWT excluded), TWT Type (TWT Type) subfield or other names, This application is not limited.

Optionally, the first frame may be a unicast frame.

Step 2202: The first device sends the first frame to the second device, and accordingly, the second device receives the first frame from the first device.

Wherein, the first device may be an R-TWT scheduling AP (R-TWT scheduling AP), and the second device may be an R-TWT scheduled site (R-TWT scheduled STA).

Step 2203: The second device removes the TWT indicated by the eleventh field.

For example, the second device may determine the type of TWT to be removed based on the specific indication of the field in the first frame in step 2201, and then perform corresponding removal. For details, please refer to the relevant description in step 2201.

Based on the above communication method, the type of TWT to be removed can be flexibly indicated through the eleventh field in the first frame, thereby clarifying the TWT that needs to be removed.

Figure 23 shows a schematic flowchart of another communication method provided by an embodiment of the present application. In the communication method shown in Figure 23, the type of TWT to be removed can be indicated through the twelfth field in the first frame, thereby clarifying the TWT that needs to be removed. By way of example, the process of this method may include:

Step 2301: The first device determines the first frame. The first frame includes a twelfth field. The twelfth field may be used to indicate one of the following: removal of all TWTs, removal of all TWTs except R-TWT. Removal of external TWT or removal of all R-TWT.

Specifically, the eleventh field is similar to the eleventh field involved in the embodiment described in Figure 22. Please refer to the description of the eleventh field in the above step 2201, which will not be described in detail here.

Step 2302: The first device sends the first frame to the second device, and accordingly, the second device receives the first frame from the first device.

Among them, the first device can be an R-TWT scheduled site (R-TWT scheduled STA), and the second device can be an R-TWT scheduling AP (R-TWT Scheduling AP).

Step 2303: The second device sends an acknowledgment frame to the first device, and accordingly, the first device receives the acknowledgment frame from the second device.

Step 2304: The first device removes the TWT indicated by the twelfth field.

For example, after receiving the acknowledgment frame, the first device can determine the type of TWT to be removed based on the specific indication of the field in the first frame in step 2301, and then perform a corresponding pause. For details, please refer to the relevant description in step 2301. .
