Description

Technical Field

[0001] The present application belongs to the field of WIFI communication technology, and specifically relates to a communication method, device, equipment and storage medium. Background Art

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

[0003] In the scenario of multiple Basic Service Set Identifiers (BSSIDs), in order to prevent other STAs from occupying the channel during the R-TWT service period, all R-TWT elements indicating the R-TWT service period must be included in the multi-BSSID elements of the beacon frame and outside the multi-BSSID elements of the beacon frame. This results in a large amount of duplicate information in the beacon frame, that is, the signaling load of the beacon frame is large. Summary of the invention

[0058] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] In this application, "and / or" is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article indicates that the associated objects before and after are in an "or" relationship.

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

[0061] The first, second, etc. descriptions in this application are only used for illustration and distinction of the described objects, and have no order, nor do they represent a special limitation on the number of devices in the embodiments of this application, and cannot constitute any limitation on the embodiments of this application. For example, the first silent element and the second silent element are only used to distinguish different silent elements, and do not represent the difference in priority or importance of the two silent elements.

[0062] In this application, "exemplary", "in some embodiments", "in other embodiments", etc. are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" in this application should not be interpreted as being more preferred or more advantageous than other embodiments or designs. Specifically, the use of the word "exemplary" is intended to present concepts in a concrete way.

[0063] In order to explain the present application more clearly, the relevant technologies involved in the present application are first introduced below.

[0064] 1. R-TWT Service Period

[0065] The R-TWT service period can be used for low-latency services with periodic data transmission. It is a broadcast target wake-up time (TWT). Its start time, duration, and period are broadcast in the beacon frame. STAs that want to use the R-TWT service period sign a contract with the AP to use the R-TWT service period through the R-TWT-related signaling process. The STA that successfully signs the contract is called the member STA of the R-TWT service period. During the R-TWT service period, the AP seizes the channel to perform downlink data transmission to the member STA or schedules the member STA to perform uplink data transmission. Other STAs avoid transmitting data during the R-TWT service period. There are two ways to avoid this:

[0066] (1) EHT STAs that support the R-TWT service period can parse the R-TWT elements introduced by EHT, and can actively avoid them based on the relevant information of the R-TWT service period (EHT STAs that do not support the 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 element newly introduced by EHT, a quiet period (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 occupying the channel for transmission during the R-TWT service period.

[0068] 2. Multiple BSSID Sets

[0069] A physical device can logically play multiple APs, where the AP that sends the beacon frame is the AP corresponding to the transmitted BSSID, and the other APs are APs corresponding to the non-transmitted BSSID. The non-transmitted BSSID is indicated by the non-transmitted BSSID profile subelement in the multi-BSSID element in the beacon frame.

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

[0071] In a multiple BSSID set scenario, all R-TWT elements indicating R-TWT service periods must be included in each non-transmission BSSID summary sub-element in the multiple BSSID element and also included outside the multiple BSSID element.

[0072] Each non-transmitting BSSID Summary sub-element in the Multi-BSSID element contains all R-TWT elements in order to:

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

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

[0075] The purpose of including all R-TWT elements outside of the Multi-BSSID element is to:

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

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

[0078] For example, if there is one transmission BSSID and three non-transmission BSSIDs in the multi-BSSID set, 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 multi-BSSID element of the beacon frame, each non-transmission BSSID summary sub-element carries 16 R-TWT elements, of which 4 are R-TWT elements of the current BSSID and the other 12 are R-TWT elements of the other 3 BSSIDs; then there are a total of 16*3=48 R-TWT elements in the multi-BSSID element. In addition to the multi-BSSID element of the beacon frame, there are a total of 16 R-TWT elements, of which 4 are R-TWT elements of the transmission BSSID and the other 12 are R-TWT elements of the non-transmission BSSID. There are a total of 64 R-TWT elements in the entire beacon frame.

[0079] The beacon frame also includes 16 silent elements, each of which indicates a silent period. Each silent period can correspond to the R-TWT service period indicated by the R-TWT element outside the multi-BSSID element to avoid other STAs with low EHT versions from occupying the channel for transmission during the R-TWT service period.

[0080] In the above scheme, the beacon frame carries more R-TWT elements, which makes the signaling load of the beacon frame larger.

[0081] In order to reduce the signaling load of the beacon frame, in the related technology, only the R-TWT elements belonging to its own BSSID can be carried in each non-transmission BSSID summary sub-element, and rules are provided: the STA associated with the non-transmission BSSID avoids the R-TWT service period of other non-transmission BSSIDs and the R-TWT service period of the transmission BSSID, and the related R-TWT elements come from outside the multi-BSSID elements.

[0082] For example, if there is one transmission BSSID and three non-transmission BSSIDs in the multi-BSSID set, 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 multi-BSSID element of the beacon frame, each non-transmission BSSID summary sub-element carries 4 R-TWT elements of the current BSSID, so there are 4*3=12 R-TWT elements in the multi-BSSID element. In addition to the multi-BSSID element of the beacon frame, there are a total of 16 R-TWT elements, of which 4 are R-TWT elements of the transmission BSSID and the other 12 are R-TWT elements of the non-transmission BSSID. There are a total of 28 R-TWT elements in the entire beacon frame.

[0083] The beacon frame also includes 16 silent elements, each of which indicates a silent period. Each silent period can correspond to the R-TWT service period indicated by the R-TWT element outside the multi-BSSID element to avoid other STAs with low EHT versions from occupying the channel for transmission during the R-TWT service period.

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

[0085] In order to solve the above technical problems, the present application uses the silent element in the beacon frame to indicate the R-TWT element of the non-transmission BSSID, further reducing the number of R-TWT elements other than the non-transmission BSSID element and reducing the signaling load of the beacon frame.

[0086] The technical solution shown in the present application is described in detail below through specific embodiments. It should be noted that the following embodiments can exist independently or in combination with each other, and the same or similar contents will not be described repeatedly in different embodiments.

[0087] Figure 3 A flow chart of a communication method provided in the application embodiment. Figure 3 , the method comprising:

[0088] S301. A network device sends a beacon frame to a terminal device.

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

[0090] A network device can send a beacon frame to multiple terminal devices by broadcasting.

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

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

[0093] The first silence element may refer to a silence element associated with a non-transmission BSSID.

[0094] By indicating the R-TWT element of the non-transmission BSSID through the first silent element, the number of R-TWTs outside the multi-BSSID elements can be reduced, saving the signaling overhead of the beacon frame.

[0095] In a possible implementation, each first silence element includes first silence period information, where the first silence period information is used to indicate the first silence period; and the 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 silent period overlaps with a first R-TWT service period, it means that the EHT STA that does not support R-TWT can seize the channel for transmission during the first silent period; other STAs, such as non-member STAs that support R-TWT, low-version STAs, etc., can avoid seizing the channel during the first silent period through the role of the first silent element.

[0097] When the first indication information indicates that the first silent period does not overlap with a first R-TWT service period, all non-member STAs can prohibit channel preemption during the first silent period through the action of the first silent element so that the AP can measure the channel, etc.

[0098] An EHT STA that does not support R-TWT may determine whether it can seize the channel by identifying the first indication information in the first silence element.

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

[0100] The second silence element may refer to a silence element associated with the transmission BSSID.

[0101] In a possible implementation, each second silence element includes second silence period information, where the second silence period information is used to indicate the second silence period; and the 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 silent period overlaps with a second R-TWT service period, it means that the EHT STA that does not support R-TWT can seize the channel for transmission during the second silent period; other STAs, such as non-member STAs that support R-TWT, low-version STAs, etc., can avoid seizing the channel during the second silent period through the role of the second silent element.

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

[0104] An EHT STA that does not support R-TWT may determine whether to seize the channel by identifying the second indication information in the second silent element.

[0105] For example, if there is one transmission BSSID and three non-transmission BSSIDs in the multi-BSSID set, 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 multi-BSSID element of the beacon frame, each non-transmission BSSID summary sub-element carries 4 R-TWT elements of the BSSID, so there are 4*3=12 R-TWT elements in the multi-BSSID element. In addition to the multi-BSSID element of the beacon frame, there are 4 R-TWT elements of the transmission BSSID. There are a total of 16 R-TWT elements in the entire beacon frame.

[0106] The beacon frame also includes 16 silent elements, each of which indicates a silent period, among which the silent periods indicated by 4 silent elements can respectively correspond to the R-TWT service periods indicated by the 4 R-TWT elements outside the multi-BSSID element, and the silent periods indicated by the remaining 12 silent elements can respectively correspond to the R-TWT service periods indicated by the 12 R-TWT elements in the multi-BSSID element, that is, the silent period indicated by each silent element overlaps with its corresponding R-TWT service period.

[0107] In a possible implementation manner, a new field may be used in the quiet element to indicate the first indication information or the second indication information, and the new field may be called a quiet usage field.

[0108] Figure 5 This is a schematic diagram of the structure of the silent element provided in the embodiment of the present application. Figure 5 The silence element includes an element identifier (Element Identifier, Element ID) field, a length (Length) field, a silence count (QuietCount) field, a silence period (Quiet Period) field, a silence duration (Quiet Duration) field, a silence offset (Quiet Offset) field and a silence purpose field.

[0109] Among them, the silence count field is set to the number of target beacon transmission times (TBTT) during the beacon interval until the next silence element starts. The silence period field is set to the period of the silence period defined by the silence element, in units of beacon intervals, and 0 represents a single silence (non-periodic occurrence). The silence duration field is set to the length of the silence period. The silence offset field is set to the offset of the start time of the silence period relative to the TBTT, and the value of the silence offset field is less than one beacon interval. The silence purpose field is used to indicate whether the R-TWT service period overlaps with the silence period (Quiet Interval). If they do not overlap, it is set to 0.

[0110] Based on any of the above embodiments, Figure 6 The communication method of the present application is described in detail.

[0111] Figure 6 A flow chart of another communication method provided in an embodiment of the present application. Figure 6 , the method comprising:

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

[0115] S602. Determine, based on the indication information, whether the silent period overlaps with an R-TWT service period.

[0116] If yes, execute S603.

[0117] If not, channel preemption is prohibited during the corresponding silent period.

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

[0119] S603: The terminal device seizes the channel for transmission during the silent period.

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

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

[0122] The terminal device seizes the channel for transmission during the silent period, which may refer to the terminal device seizing the channel for data or signaling transmission with the network device or other terminal devices during the silent period.
