Description

Technical Field

[0001] This application belongs to the field of WIFI communication technology, specifically relating to a communication method, device, equipment, and storage medium. Background Technology

[0002] The Institute of Electrical and Electronics Engineers (IEEE) 802.11be (Extremely High Throughput, EHT) introduces a Restricted Target Wake Time (R-TWT) service period. The R-TWT service period is used for transmitting low-latency service data and is announced by the Access Point (AP) in a beacon frame. During the R-TWT service period, the non-Access Point Station (STA) that has obtained the right to use the channel can transmit data with the AP; other STAs cannot preempt the channel for transmission during the R-TWT service period.

[0003] In scenarios involving multiple Basic Service Set Identifiers (BSSIDs), to prevent other STAs from preempting the channel during the R-TWT service period, all R-TWT elements indicating the R-TWT service period must be included both within and outside the multiple BSSID elements of the beacon frame. This results in a large amount of duplicate information in the beacon frame, meaning a high signaling load. Summary of the Invention

For example, A and / or B can represent three cases: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this document indicates that the preceding and following related objects have an "or" relationship.

[0060] In this application, "at least one" means one or more. "More than one" means two or more.

[0061] The use of terms like "first" and "second" in this application is for illustrative purposes and to distinguish the objects being described. They do not indicate any particular order and do not imply a specific limitation on the number of devices in the embodiments of this application, nor do they constitute any restriction on the embodiments of this application. For example, "first silent element" and "second silent element" are only used to distinguish different silent elements and do not indicate a difference in priority or importance between the two silent elements.

[0062] In this application, terms such as "exemplary," "in some embodiments," and "in other embodiments" are used to indicate that something is an example, illustration, or description. Any embodiment or design described as "exemplary" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Rather, the term "exemplary" is used to present the concept in a specific manner.

[0063] To explain this application more clearly, the relevant technologies involved in this application will be introduced first below.

[0064] 1. R-TWT Service Period

[0065] R-TWT service periods can be used for low-latency services with periodic data transmission. It is a type of broadcast Target Wake Time (TWT), with its start time, duration, and period broadcast in beacon frames. STAs wishing to use the R-TWT service period subscribe to the AP through R-TWT-related signaling procedures. Successfully subscribed STAs are called member STAs for that R-TWT service period. During the R-TWT service period, the AP preempts the channel to perform downlink data transmission to member STAs or schedules member STAs to perform uplink data transmission. Other STAs avoid transmitting data during the R-TWT service period in two ways:

[0066] (1) EHT STAs that support R-TWT service period can parse the R-TWT elements introduced by EHT and can actively avoid them based on the relevant information of R-TWT service period (EHT STAs that do not support R-TWT service period do not need to avoid them).

[0067] (2) For STAs with versions lower than EHT, since they cannot parse the R-TWT elements newly introduced by EHT, a quiet interval synchronized with the R-TWT service period can be set through the quiet element to prevent STAs with versions lower than EHT from preempting the channel for transmission during the R-TWT service period.

[0068] 2. Multiple BSSID sets

[0069] A single physical device can logically act as multiple access points (APs). The AP that sends the beacon frame corresponds to the transmitted BSSID, while the other APs correspond to the non-transmitted BSSIDs. The non-transmitted BSSID is indicated by the non-transmitted BSSID profile subelement within the multi-BSSID element of the beacon frame.

[0070] The application scenario of this application can be a multi-BSSID set scenario. It should be noted that the communication method provided in this application can be applied not only to the above-mentioned scenario, but also to other similar scenarios. The communication method provided in this application includes, but is not limited to, the above-mentioned application scenarios.

[0071] In a multi-BSSID set scenario, all R-TWT elements indicating the R-TWT service period must be included both in each non-transport BSSID summary sub-element within the multi-BSSID element and outside the multi-BSSID element.

[0072] The reason why each nontransferable BSSID summary sub-element in a multi-BSSID element includes all R-TWT elements is:

[0073] (1) Allow STAs associated with this non-transmission BSSID to avoid or use the R-TWT service period of this BSSID (R-TWT scheduling information is 0-2);

[0074] (2) Allow the STA associated with the non-transport BSSID to avoid the R-TWT service period of other non-transport BSSIDs and transport BSSIDs (R-TWT scheduling information is 3).

[0075] Including all R-TWT elements in addition to the multi-BSSID elements is for the following reasons:

[0076] (1) Allow the STA associated with this transmission BSSID to avoid or use the R-TWT service period of this BSSID (R-TWT scheduling information is 0-2);

[0077] (2) Allow the STA associated with the transmission BSSID to avoid the R-TWT service period of the non-transmission BSSID (R-TWT scheduling information is 3).

[0078] For example, if a multi-BSSID set has one transport BSSID and three non-transport BSSIDs, and each BSSID has four R-TWT service periods, then the physical AP has a total of 16 R-TWT service periods. Figure 1As shown, in the multiple BSSID elements of the beacon frame, each non-transmission BSSID summary sub-element contains 16 R-TWT elements. Four of these are R-TWT elements for the current BSSID, and the other 12 are R-TWT elements for the other three BSSIDs. Therefore, there are a total of 16 * 3 = 48 R-TWT elements in the multiple BSSID elements. In addition to the multiple BSSID elements in the beacon frame, there are 16 R-TWT elements, of which 4 are R-TWT elements for the transmission BSSIDs, and the other 12 are R-TWT elements for the non-transmission BSSIDs. The entire beacon frame contains a total of 64 R-TWT elements.

[0079] The beacon frame also includes 16 silence elements, each indicating a silence period. Each silence period can correspond to the R-TWT service period indicated by the R-TWT element in addition to the multi-BSSID element, in order to prevent other STAs with lower EHT versions from preempting the channel for transmission during the R-TWT service period.

[0080] In the above scheme, the beacon frame carries a large number of R-TWT elements, resulting in a large signaling load on the beacon frame.

[0081] To reduce the signaling load of beacon frames, related technologies can carry only the R-TWT element belonging to its own BSSID in each non-transport BSSID summary sub-element, while providing the rule that STAs associated with this non-transport BSSID should avoid the R-TWT service periods of other non-transport BSSIDs and transport BSSIDs, and that the related R-TWT elements come from outside the multi-BSSID elements.

[0082] For example, if a multi-BSSID set has one transport BSSID and three non-transport BSSIDs, and each BSSID has four R-TWT service periods, then the physical AP has a total of 16 R-TWT service periods. Figure 2 As shown, in the multiple BSSID elements of the beacon frame, each non-transmission BSSID summary sub-element carries 4 R-TWT elements for its own BSSID. Therefore, there are a total of 4 * 3 = 12 R-TWT elements in the multiple BSSID elements. Besides the multiple BSSID elements in the beacon frame, there are a total of 16 R-TWT elements, of which 4 are for transmission BSSIDs and the other 12 are for non-transmission BSSIDs. The entire beacon frame contains a total of 28 R-TWT elements.

[0083] The beacon frame also includes 16 silence elements, each indicating a silence period. Each silence period can correspond to the R-TWT service period indicated by the R-TWT element in addition to the multi-BSSID element, in order to prevent other STAs with lower EHT versions from preempting the channel for transmission during the R-TWT service period.

[0084] Although this scheme reduces the R-TWT elements carried in beacon frames, the signaling load of beacon frames is still relatively large.

[0085] To address the aforementioned technical issues, this application uses silent elements in the beacon frame to indicate R-TWT elements that do not transmit BSSIDs, further reducing the number of R-TWT elements other than non-transmit BSSID elements and lowering the signaling load of the beacon frame.

[0086] The technical solutions shown in this application will now be described in detail through specific embodiments. It should be noted that the following embodiments may exist independently or in combination with each other; for the same or similar content, the description will not be repeated in different embodiments.

[0087] Figure 3 A flowchart illustrating a communication method provided in the application embodiment is shown below. Please refer to [link / reference]. Figure 3 The method includes:

[0088] S301, The network device sends a beacon frame to the terminal device.

[0089] In other words, the terminal device receives beacon frames sent by the network device.

[0090] Network devices can broadcast beacon frames to multiple terminal devices.

[0091] The beacon frame includes at least one first silence element and multiple BSSID elements, the multiple BSSID elements including at least one first R-TWT element; wherein each first R-TWT element is used to indicate the first R-TWT service period, the first R-TWT service period is the service period associated with a non-transmitting BSSID; each first silence element includes first indication information, the first indication information is used to indicate that the first silence element corresponds to a first R-TWT element.

[0092] The first silence element corresponding to a first R-TWT element can mean that the silence period indicated by the first silence element overlaps with the first R-TWT service period indicated by a first R-TWT element.

[0093] The first silent element can refer to a silent element associated with a non-transmitting BSSID.

[0094] By indicating the R-TWT element that is not a transmission BSSID through the first silent element, the number of R-TWTs other than the multi-BSSID elements can be reduced, thus saving the signaling overhead of the beacon frame.

[0095] In one possible implementation, each first silence element includes first silence period information, which is used to indicate a first silence period; first indication information is used to indicate whether the first silence period overlaps with a first R-TWT service period.

[0096] When the first indication information indicates that the first silence period overlaps with a first R-TWT service period, it means that an EHT STA that does not support R-TWT can preempt the channel for transmission during the first silence period; other STAs, such as non-member STAs that support R-TWT, lower version STAs, etc., can avoid preempting the channel during the first silence period through the action of the first silence element.

[0097] When the first indication information indicates that the first silence period does not overlap with a first R-TWT service period, all non-member STAs can use the first silence element to prevent channel preemption during the first silence period, so that the AP can measure the channel, etc.

[0098] EHT STAs that do not support R-TWT can determine whether they can preempt the channel by recognizing the first indication information in the first silence element.

[0099] In one possible implementation, the beacon frame further includes at least one second silence element and at least one second R-TWT element; wherein each second R-TWT element is used to indicate a second R-TWT service period, which is a service period associated with the transmission BSSID; each second silence element includes second indication information, which is used to indicate that the second silence element corresponds to a second R-TWT element.

[0100] The second silent element can refer to the silent element associated with the transmitted BSSID.

[0101] In one possible implementation, each second silence element includes second silence period information, which is used to indicate a second silence period; second indication information is used to indicate whether the second silence period overlaps with a second R-TWT service period.

[0102] When the second indication information indicates that the second silence period overlaps with a second R-TWT service period, it means that EHT STAs that do not support R-TWT can preempt the channel for transmission during the second silence period; other STAs, such as non-member STAs that support R-TWT, lower version STAs, etc., can avoid preempting the channel during the second silence period through the action of the second silence element.

[0103] When the second indication information indicates that the second quiet period does not overlap with a second R-TWT service period, all STAs are prohibited from preempting the channel during the second quiet period so that the AP can measure the channel, etc.

[0104] EHT STAs that do not support R-TWT can determine whether to preempt the channel by recognizing the second indication information in the second silence element.

[0105] For example, if a multi-BSSID set has one transport BSSID and three non-transport BSSIDs, and each BSSID has four R-TWT service periods, then the physical AP has a total of 16 R-TWT service periods. Figure 4 As shown, in the multiple BSSID elements of the beacon frame, each non-transmission BSSID summary sub-element carries 4 R-TWT elements for its own BSSID, resulting in a total of 4*3=12 R-TWT elements in the multiple BSSID elements. In addition to the multiple BSSID elements in the beacon frame, there are 4 R-TWT elements for the transmission BSSIDs. The entire beacon frame contains a total of 16 R-TWT elements.

[0106] The beacon frame also includes 16 silence elements, each indicating a silence period. Among them, the silence periods indicated by 4 silence elements can correspond to the R-TWT service periods indicated by the 4 R-TWT elements other than the multi-BSSID elements, and the silence periods indicated by the remaining 12 silence elements can correspond to the R-TWT service periods indicated by the 12 R-TWT elements within the multi-BSSID elements. That is, the silence period indicated by each silence element overlaps with its corresponding R-TWT service period.

[0107] In one possible implementation, a new field can be used in the silent element to indicate the first or second indication information. This new field can be called the Quiet Usage field.

[0108] Figure 5 This is a schematic diagram of the structure of a silent element provided in an embodiment of this application. Please refer to [link / reference]. Figure 5 The silent element includes the Element Identifier (Element ID) field, the Length field, the QuietCount field, the Quiet Period field, the Quiet Duration field, the Quiet Offset field, and the Quiet Purpose field.

[0109] The Quiet Count field is set to the number of Target Beacon Transmission Time (TBTT) during the beacon interval until the start of the next Quiet element. The Quiet Period field is set to the period during which the Quiet period defined by this Quiet element occurs, in beacon intervals; 0 indicates a single Quiet (non-periodic occurrence). The Quiet Duration field is set to the length of the Quiet period. The Quiet Offset field is set to the offset of the start time of the Quiet period relative to the TBTT; the value of the Quiet Offset field is less than one beacon interval. The Quiet Purpose field indicates whether the R-TWT service period overlaps with the Quiet Interval; if they do not overlap, it is set to 0.

[0110] Based on any of the above embodiments, the following, in conjunction with Figure 6 The communication method described in this application is explained in detail.

[0111] Figure 6 This is a flowchart illustrating another communication method provided in an embodiment of this application. Please refer to... Figure 6 The method includes:

[0112] S601. The network device sends a beacon frame to the terminal device. The beacon frame includes indication information.

[0113] It should be noted that the execution process of S601 can be found in the execution process of S301, and will not be repeated here.

[0114] The instruction information can refer to either the first instruction information or the second instruction information.

[0115] S602. Based on the instruction information, determine whether the quiet period overlaps with an R-TWT service period.

[0116] If so, then execute S603.

[0117] If not, then preemption of the channel is prohibited during the corresponding quiet period.

[0118] Determining whether a quiet period overlaps with a R-TWT service period can be expressed as whether a first quiet period overlaps with a first R-TWT service period, and / or whether a second quiet period overlaps with a second R-TWT service period.

[0119] S603. Terminal equipment preempts the channel for transmission during the quiet period.

[0120] The terminal device can be an EHT STA that does not support R-TWT.

[0121] The silent period can refer to either the first silent period or the second silent period.

[0122] When a terminal device preempts a channel for transmission during a quiet period, it can refer to the terminal device preempting a channel during a quiet period to transmit data or signaling with network devices or other terminal devices.
