[0017] The term "and / or" in the embodiments of the present disclosure describes the related relationship of related objects and indicates that three relationships may exist. For example, A and / or B may indicate three cases: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the context objects are in an "or" relationship.

[0018] In the embodiments of the present disclosure, the term "plurality" means two or more, and similarly for other counters.

[0019] Hereinafter, the technical solutions in the embodiments of the present disclosure will be clearly and completely described with reference to the drawings in the embodiments of the present disclosure, but it is clear that the described embodiments are only some embodiments of the present disclosure, and not all embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative labor belong to the scope of protection of the present disclosure.

[0020] The embodiments of the present disclosure provide a signal processing method, a signal processing device, an electronic device and a storage medium, which are used to provide related information of an rTWT information element, and meet the needs of low-latency transmission.

[0021] Here, the method and the apparatus are based on the same application idea, and the principles by which the method and the apparatus solve the problems are similar, so the implementations of the apparatus and the method can refer to each other and the overlapping parts are omitted.

[0022] As shown in Fig. 1, an embodiment of the present disclosure provides a signal processing method, and optionally, the method can be applied to an AP, and in a wireless local area network, a Basic Service Set (BSS) is composed of an AP and one or more Stations (STAs) communicating with the AP. A Basic Service Set can be connected to a Distribution System (DS) through the AP, and can access another Basic Service Set to form an Extended Service Set (ESS). The AP and the STAs communicate with each other through a communication link.

[0023] The method includes the following steps.

[0024] In step 101, a target radio frame is transmitted, where the target radio frame includes a restricted target wake time (rTWT) element and a Quiet Element corresponding to the rTWT element.

[0025] In the low-latency transmission scene, the real-time data traffic of many applications has strict latency requirements, for example, the average latency or maximum latency ranges from several milliseconds to tens of milliseconds, and the application expects the real-time data traffic to have extremely small jitter and strong reliability. The rTWT macanism allows the AP to provide more predictable latency using enhanced medium access protection macanism and resource reservation macanism, so that the AP can reduce the worst-case latency and / or jitter and provide more reliable services. Therefore, the rTWT macanism can transmit low-latency services, for example, services with average latency less than 10 milliseconds.

[0026] The AP transmits a target wireless frame to the STA, and optionally the target wireless frame is, for example, a beacon frame, a probe response frame, a multilink probe response (ML probe response) frame, etc.

[0027] In order to prevent other STAs from interfering with the low latency transmission service transmitted by the target STA and other STAs not participating in the rTWT session from accessing the channel while transmitting a target wireless frame to the STA, the AP carries a Quiet Element in the target wireless frame, and creates an overlap time between the Quiet Period (time information / duration information) of the Quiet Element and the duration information or service period (SP time) of the rTWT. During the overlap time, a station is not allowed to access and interfere with the low latency transmission service when there is no low latency service, thereby realizing the protection of the rTWT by the Quiet Element. For example, when a Beacon frame includes a Quiet Element and an rTWT, a station (when there is no low latency service) is restricted from accessing within the overlap time between the Quiet Element and the duration information or service period of the rTWT. Specifically, taking the target wireless frame as an example, the format of the Quiet Element information is shown in Table 1.

[0028] [Table 1]

[0029] Here, the Quiet Count field indicates the number of Target Beacon Transmission Times (TBTTs), that is, the beacon interval until the next quiet period begins.

[0030] The Quiet Period field represents the quiet periods, each of which has a duration of a number of beacon intervals. For example, if the Quiet Period field is set to 0, this indicates that no periodic quiet intervals are defined, and if the Quiet Period field is set to 1, this indicates that there are periodic quiet intervals.

[0031] The Quiet Duration field indicates the duration of the quiet period, expressed in TU.

[0032] The Quiet Offset field indicates the offset of the quiet period at which the TBTT specified by the Quiet Count field starts, and is expressed in TU. The value of the Quiet Offset field is smaller than one beacon interval. Quiet Offset is a time offset. Normally, quiet time starts immediately after the Beacon, and the stop time is Quiet Duration, but this time can also be delayed, in which case the delayed time is Quiet Offset.

[0033] The target radio frame includes a Quiet Element and a Limited Target Wake Time (rTWT) element corresponding to each of the Quiet Elements. That is, at least one or more rTWT elements have a corresponding Quiet Element, and one or more Quiet Elements are included in the Beacon and the Probe Response, so that overlapping Quiet Intervals can be scheduled, and an AP (e.g., an Enhancements for extremely high throughput (EHT) AP) transmits the Beacon and the Probe Response to realize protection of the rTWT by the Quiet Element, and prevents legacy STAs and other STAs not participating in the rTWT session from accessing the channel and interfering with the low latency transmission service transmitted by the target STA.

[0034] In addition, the target radio frame includes an rTWT element and a Quiet Element corresponding to the rTWT element, and only one rTWT element may have a corresponding Quiet Element, or at least two rTWT elements may have corresponding Quiet Elements, and the embodiments of the present disclosure are not limited thereto.

[0035] In addition, in the embodiment of the present disclosure, the AP and (target) STA can support a single-link device and can also support a multi-link device. In a multi-link scenario, the AP and the STA are respectively indicated as AP MLD and non-AP MLD. For ease of explanation, the following description of a multi-link scenario mainly focuses on an example in which one AP and one STA communicate with each other via multi-links, but the embodiment of the present disclosure is not limited thereto.

[0036] In an embodiment of the present disclosure, an AP transmits a target radio frame to a STA, and the target radio frame includes an rTWT element and a Quiet Element corresponding to each of the rTWT elements. By protecting the rTWT element with the Quiet Element, the AP reduces the worst-case delay and / or jitter, and provides a more reliable service for low-latency transmission services. An embodiment of the present disclosure provides a configuration method and transmission method of an rTWT information element.

[0037] As shown in FIG. 2, an embodiment of the present disclosure further provides a signal processing method, which can be optionally applied to an AP, and includes the following steps:

[0038] In step 201, a target radio frame is transmitted, in which a quiet factor and an rTWT factor are set according to the following aspects of case 1 and / or case 2.

[0039] In case 1, a first ranking order of a first quiet element in the quiet element is the same as a second ranking order of a first rTWT element in the rTWT element, and the first rTWT element is the rTWT element corresponding to the first quiet element.

[0040] In case 1, the quiet element and the rTWT element appear in a pair with one-to-one correspondence. For a target radio frame, all the quiet elements are ranked respectively to obtain a ranking Ra of the quiet elements, where a denotes the ranking value, and all the rTWT elements are ranked respectively to obtain a ranking Rb of the rTWT elements, where b denotes the ranking value, and for a pair of quiet elements and rTWT elements, the ranking of the quiet elements in the quiet elements is a first ranking order Ra, and the ranking of the rTWT elements in the rTWT elements is a second ranking order Ra, where a=b.

[0041] In case 2, the quiet element includes a time offset value, and a second rTWT element carries a time offset sub-domain, which includes the time offset value of a target quiet element corresponding to the rTWT element.

[0042] As shown in the Quiet Offset field in Table 1 above, the quiet element includes a time offset value, and the time offset value is unique. The second rTWT element carries a time offset subdomain, where the time offset subdomain includes time offset values ​​of target quiet elements corresponding to one or at least two of the rTWT elements in the target radio frame, and the number of time offset values ​​of the time offset subdomain is the same as the number of target quiet elements, when the time offset subdomain includes time offset values ​​of target quiet elements corresponding to each of the rTWT elements.

[0043] For example, the target radio frame includes N rTWT elements, one of which is a second rTWT element, and the time offset values ​​of the target quiet elements corresponding to each of the N rTWT elements are indicated in the time offset subdomain of the second rTWT element, and thus the target quiet elements corresponding to each rTWT element can be determined based on the time offset values ​​of the target quiet elements corresponding to each of the N rTWT elements. In one alternative embodiment, the rTWT element includes at least one of first indication information and second indication information, where the first indication information indicates that the service corresponding to the target radio frame includes a low-latency service, and the first indication information is an identifier of the low-latency transmission service, identifying that the rTWT element is used for transmitting the low-latency service, for example, the AP broadcasts the identifier of the low-latency transmission service.

[0044] The second indication information indicates that the service corresponding to the target radio frame includes an uplink service or a downlink service, and a service period (Service Period, SP) of the low latency service is divided into uplink and downlink, and the second indication information is represented by a 1-bit bit, for example, “0” can identify an uplink service and “1” can identify a downlink service.

[0045] In one alternative embodiment, the access point device comprises a single link device or a multi-link device.

[0046] An access point device can support multi-link communication or single-link communication. Take multi-link communication as an example. In a wireless communication system, an AP and a STA can be a multi-link device (MLD), and the MLD supports the function of simultaneously transmitting and / or receiving on multiple links at the same time. Therefore, multiple links can exist between the AP and the STA to communicate.

[0047] As shown in FIG. 3 , an embodiment of the present disclosure further provides a signal processing method, optionally, the method can be applied to an AP, where the AP includes a multi-link device (AP MLD), and the method can include step 301 and / or step 302.

[0048] In step 301, a target radio frame corresponding to a communication link is transmitted between each station, and the target radio frame includes a restricted target wake time (rTWT) element and a quiet element corresponding to the rTWT element.

[0049] AP MLD broadcasts a targeted wireless frame on each communication link that is mapped to a low latency service.

[0050] Alternatively, the communication links referred to in step 301 are communication links that transmit low-latency transmission services, and the AP may not transmit the target wireless frame on some communication links that do not transmit low-latency transmission services with the station.

[0051] In step 302, transmit radio frame information of each of the communication links over at least one of the communication links, where the radio frame information includes identifier information of the target communication link corresponding to the target radio frame and each of the target radio frames, the identifier information including at least one of a link identifier (Link ID) and a link identifier set bitmap (Link ID Set Bitmap). The target radio frame includes a restricted target wake time (rTWT) element and a quiet element (Quiet Element) corresponding to the rTWT element.

[0052] Optionally, the communication links referred to in step 302 are communication links that carry low-latency transmission services, and for some communication links that do not carry low-latency transmission services, the AP does not broadcast its radio frame information.

[0053] The AP MLD can broadcast radio frame information on at least one communication link between the STA and another communication link, the radio frame information including identifier information of the target radio frame and the target communication link corresponding to each of the target radio frames, the identifier information including at least one of a link identifier (Link ID) and a link identifier set bitmap (Link ID Set Bitmap). For example, when the identifier information includes a Link ID Set Bitmap, the number of rTWT elements that appear is the same as the number of 1s set in the Link ID Set Bitmap, where the Link ID Set Bitmap may be 2 bytes.

[0054] As shown in FIG. 4, an embodiment of the present disclosure further provides a signal processing method, which can be optionally applied to an AP, and includes the following steps:

[0055] In step 401, a target radio frame is determined, where the target radio frame includes a restricted target wake time (rTWT) element and a Quiet Element corresponding to the rTWT element.

[0056] In the low-latency transmission scenario, the real-time data traffic of many applications has strict latency requirements, for example, the average latency or maximum latency ranges from several milliseconds to tens of milliseconds, and applications expect the real-time data traffic to have extremely small jitter and strong reliability, and the rTWT macanism allows the AP to provide more predictable latency using enhanced medium access protection macanism and resource reservation macanism, thereby allowing the AP to reduce worst-case latency and / or jitter and provide more reliable services. Therefore, the rTWT macanism can transmit low-latency services, for example, services with average latency less than 10 milliseconds.

[0057] The AP determines (or generates) a target radio frame, and optionally, the target radio frame is, for example, a Beacon frame, a Probe Response frame, an ML Probe Response frame, etc. The target radio frame includes an rTWT element and a Quiet Element corresponding to the rTWT element. In order to prevent other STAs from interfering with the low latency transmission service transmitted by the target STA and to prevent legacy STAs and other STAs not participating in the rTWT session from accessing the channel, the target radio frame carries a Quiet Element, and the Quiet Period (time information / time length information) of the Quiet Element is overlapped with the time length information or service period (SP) of the rTWT to protect the rTWT by the Quiet Element.

[0058] In step 402, the target radio frame is transmitted.

[0059] The AP transmits the target wireless frame to the STA, and protects the rTWT element by the Quiet Element, so that the AP reduces the maximum delay and / or jitter and provides more reliable service for the low-latency transmission service.

[0060] In one alternative embodiment, the target radio frame includes at least one of a beacon frame, a probe response frame, a multilink probe response frame, an association response frame, and a reassociation response frame, although other forms of the target radio frame may be included, and the embodiments of the present disclosure are not limited thereto.

[0061] In an embodiment of the present disclosure, an AP sends a target radio frame to a STA, and the target radio frame includes an rTWT element and a Quiet Element corresponding to each of the rTWT elements, and by protecting the rTWT elements with the Quiet Element, the AP reduces the maximum delay and / or jitter and provides more reliable services for low-latency transmission services.

[0062] 5, an embodiment of the present disclosure further provides a signal processing method applied to a station device STA (or target STA), where the STA may refer to a device providing voice and / or data connectivity to a user, a handheld device with wireless connection function, or other processing device connected to a wireless modem, etc. In a wireless local area network, a BSS may be composed of an AP and one or more station STAs communicating with the AP. Communication is performed between the AP and the STAs via a communication link.

[0063] The method includes the following steps.

[0064] In step 501, a target radio frame is received, the target radio frame including a restricted target wake time (rTWT) element and a Quiet Element corresponding to the rTWT element.

[0065] In low-latency transmission scenarios, the real-time data traffic of many applications has strict latency requirements, for example, the average latency or maximum latency ranges from several milliseconds to tens of milliseconds, and applications expect the real-time data traffic to have extremely small jitter and strong reliability, and the rTWT macanism allows the AP to use enhanced medium access protection macanism and resource reservation macanism to provide more predictable latency, thereby allowing the AP to reduce worst-case latency and / or jitter and provide more reliable services. Thus, the rTWT macanism can transmit low-latency services, for example, services with average latency less than 10 milliseconds.

[0066] The STA receives a target wireless frame transmitted by the AP, and optionally, the target wireless frame is, for example, a Beacon frame, a Probe Response frame, an ML Probe Response frame, etc.

[0067] When transmitting a target wireless frame to a STA (target STA), the AP carries a Quiet Element in the target wireless frame to prevent other STAs from interfering with the low latency transmission service transmitted by the target STA and to prevent legacy STAs and other STAs not participating in the rTWT session from accessing the channel, and creates an overlap time between the Quiet Period (time information / length information) of the Quiet Element and the time length information or service period (SP time) of the rTWT. During the overlap time, stations are not allowed to access and interfere with the low latency transmission service when there is no low latency service, thereby realizing the protection of the rTWT by the Quiet Element. For example, when a Beacon frame includes a Quiet Element and an rTWT, access of stations (when there is no low latency service) is restricted within the overlap time between the Quiet Element and the time length information or service period of the rTWT. Specifically, taking the target wireless frame as an example, the format of the Quiet Element information is shown in Table 2.

[0068] [Table 2]

[0069] Here, the Quiet Count field indicates the number of Target Beacon Transmission Times (TBTTs), that is, the beacon interval until the next quiet period begins.

[0070] The Quiet Period field represents the quiet periods, each of which has a duration of a number of beacon intervals. For example, if the Quiet Period field is set to 0, this indicates that no periodic quiet intervals are defined, and if the Quiet Period field is set to 1, this indicates that there are periodic quiet intervals.

[0071] The Quiet Duration field indicates the duration of the quiet period.

[0072] The Quiet Offset field indicates the offset of the quiet period at which the TBTT specified by the Quiet Count field starts, and is expressed in TU. The value of the Quiet Offset field is smaller than one beacon interval. Quiet Offset is a time offset. Normally, quiet time starts immediately after the Beacon, and the stop time is Quiet Duration, but this time can also be delayed, in which case the delayed time is Quiet Offset.

[0073] The target radio frame includes a Quiet Element and a Limited Target Wake Time (rTWT) element corresponding to each of the Quiet Elements, i.e., at least one or more rTWT elements have a corresponding Quiet Element, and the Beacon and Probe Response include one or more Quiet Elements, allowing overlapping quiet intervals to be scheduled, and an AP (e.g., an Enhancements for extremely high throughput (EHT) AP) transmits the Beacon and the Probe Response to realize protection of the rTWT by the Quiet Element and prevent legacy STAs and other STAs not participating in the rTWT session from accessing the channel and interfering with the low-latency transmission service transmitted by the target STA.

[0074] In addition, in the embodiment of the present disclosure, the AP and (target) STA can support a single-link device and can also support a multi-link device, and in a multi-link scenario, the AP and STA are respectively indicated as AP MLD and non-AP MLD. For ease of explanation, the following description of a multi-link scenario mainly focuses on an example in which one AP and one STA communicate in multi-link, but the embodiment of the present disclosure is not limited thereto.

[0075] In an embodiment of the present disclosure, a STA receives a target radio frame transmitted by an AP, and the target radio frame includes an rTWT element and a Quiet Element corresponding to each of the rTWT elements, and the rTWT element is protected by the Quiet Element, so that the AP can reduce the maximum delay and / or jitter and provide a more reliable service for a low-latency transmission service. An embodiment of the present disclosure provides a method for setting and transmitting an rTWT information element.

[0076] As an alternative embodiment, in the target radio frame, the quiet factor and the rTWT factor are set according to the following case 1 and / or case 2 aspects.

[0077] In case 1, a first ranking order of a first quiet element in the quiet element is the same as a second ranking order of a first rTWT element in the rTWT element, and the first rTWT element is the rTWT element corresponding to the first quiet element.

[0078] The quiet element and the rTWT element appear in pairs with one-to-one correspondence. For a target radio frame, all the quiet elements are ranked respectively to obtain a ranking Ra of the quiet elements, where a indicates the ranking value, and all the rTWT elements are ranked respectively to obtain a ranking Rb of the rTWT elements, where b indicates the ranking value, and for a pair of quiet elements and rTWT elements, the ranking of the quiet elements in the quiet elements is a first ranking order Ra, and the ranking of the rTWT elements in the rTWT elements is a second ranking order Ra, where a=b.

[0079] In case 2, the quiet element includes a time offset value, and a second rTWT element carries a time offset sub-domain, which includes the time offset value of a target quiet element corresponding to the rTWT element.

[0080] As shown in the Quiet Offset field in Table 1 above, the quiet element includes a time offset value, and the time offset value is unique. The second rTWT element carries a time offset sub-domain, where the time offset sub-domain includes a time offset value of a target quiet element corresponding to each of the rTWT elements in a target radio frame, and the number of time offset values ​​of the time offset sub-domain is the same as the number of target quiet elements.

[0081] For example, a target radio frame includes N rTWT elements, one of which is a second rTWT element, and in the time offset subdomain of the second rTWT element, a time offset value of a target quiet element corresponding to each of the N rTWT elements is indicated. In this way, a target quiet element corresponding to each rTWT element can be determined based on the time offset value of a target quiet element corresponding to each of the N rTWT elements.

[0082] As one optional embodiment, the rTWT element includes at least one of first indication information and second indication information, where the first indication information indicates that the service corresponding to the target radio frame includes a low-latency service, and the first indication information is an identifier of a low-latency transmission service, identifying that the rTWT element is used for transmitting the low-latency service, for example, an AP broadcasts the identifier of the low-latency transmission service.

[0083] The second indication information indicates that the service corresponding to the target radio frame includes an uplink service or a downlink service, and a service period (Service Period, SP) of the low latency service is divided into uplink and downlink, and the second indication information is represented by a 1-bit bit, for example, “0” can identify an uplink service and “1” can identify a downlink service.

[0084] In one alternative embodiment, the station device includes a single link device or a multi-link device.

[0085] A station device can support multi-link communication or single-link communication, and taking multi-link communication as an example, in a wireless communication system, an AP and a STA can be MLDs, which support the function of simultaneously transmitting and / or receiving on multiple links at the same time. Therefore, there are multiple links between an AP and a STA for communication.

[0086] As an optional embodiment, when the station device includes a multi-link device, receiving the target radio frame includes case 3 and / or case 4. In case 3, a target wireless frame corresponding to each communication link is received on a communication link between each access point, and when the AP MLD broadcasts a target wireless frame on each communication link mapped to a low latency service, the STA MLD (or non-AP MLD) receives a target wireless frame corresponding to each communication link on a communication link between each access point.

[0087] In case 4, radio frame information of each of the communication links is received over at least one of the communication links, where the radio frame information includes identifier information of the target radio frame and a target communication link corresponding to each of the target radio frames, and the identifier information includes at least one of a link identifier (Link ID) and a link identifier set bitmap (Link ID Set Bitmap).

[0088] Here, the radio frame information includes identifier information of the target radio frame and a target communication link corresponding to each of the target radio frames, and the identifier information includes at least one of a link identifier (Link ID) and a link identifier set bitmap (Link ID Set Bitmap).

[0089] The target radio frame includes a restricted target wake time (rTWT) element and a quiet element corresponding to the rTWT element.

[0090] When the AP MLD can broadcast radio frame information of other communication links through at least one communication link between the STA MLD and the AP MLD, the STA MLD receives radio frame information of each of the communication links through at least one of the communication links, the radio frame information including identifier information of the target radio frame and a target communication link corresponding to each of the target radio frames, and the identifier information includes at least one of a link identifier (Link ID) and a link identifier set bitmap (Link ID Set Bitmap). For example, when the identifier information includes a Link ID Set Bitmap, the number of rTWT elements that appear is the same as the number of Link ID Set Bitmaps that are set to "1".

[0091] In one alternative embodiment, the target radio frame includes at least one of a beacon frame, a probe response frame, a multilink probe response frame, an association response frame, and a reassociation response frame, although other forms of the target radio frame may be included, and the embodiments of the present disclosure are not limited thereto.

[0092] In an embodiment of the present disclosure, a STA receives a target radio frame transmitted by an AP, and the target radio frame includes an rTWT element and a Quiet Element corresponding to each of the rTWT elements, and by protecting the rTWT elements with the Quiet Element, the AP reduces the maximum delay and / or jitter and provides a more reliable service for low-latency transmission services.

[0093] Based on the same principle as the method provided by the embodiment of the present disclosure, the embodiment of the present disclosure further provides an access point device, in a wireless local area network, a BSS may be composed of an AP and one or more STAs communicating with the AP. A basic service set can be connected to a DS through the AP, and access another basic service set to form an extended service set (ESS). The AP and the STA communicate with each other through a communication link. As shown in FIG. 6, the access point device includes a transmission module 601 for transmitting a target wireless frame, the target wireless frame including a restricted target wake time (rTWT) element and a quiet element corresponding to the rTWT element.

[0094] In low-latency transmission scenarios, the real-time data traffic of many applications has strict latency requirements, for example, the average latency or maximum latency ranges from several milliseconds to tens of milliseconds, and applications expect the real-time data traffic to have extremely small jitter and strong reliability, and the rTWT macanism allows the AP to use enhanced medium access protection macanism and resource reservation macanism to provide more predictable latency, thereby allowing the AP to reduce worst-case latency and / or jitter and provide more reliable services. Thus, the rTWT macanism can transmit low-latency services, for example, services with average latency less than 10 milliseconds.

[0095] The AP transmits a target wireless frame to the STA, and optionally, the target wireless frame is, for example, a Beacon frame, a Probe Response frame, an ML Probe Response frame, etc.

[0096] When transmitting a target wireless frame to a STA (target STA), the AP carries a Quiet Element in the target wireless frame to prevent other STAs from interfering with the low latency transmission service transmitted by the target STA and to prevent legacy STAs and other STAs not participating in the rTWT session from accessing the channel, and creates an overlap time between the Quiet Period (time information / length information) of the Quiet Element and the time length information or service period (SP time) of the rTWT. During the overlap time, the station is not allowed to access and interfere with the low latency transmission service when there is no low latency service, thereby realizing the protection of the rTWT by the Quiet Element. For example, when a Quiet Element and rTWT are included in a Beacon frame, the access of the station (when there is no low latency service) is restricted within the overlap time between the Quiet Element and the time length information or service period of the rTWT. Specifically, taking the target wireless frame as an example, the format of the Quiet Element information is shown in Table 1.

[0097] [Table 3]

[0098] Here, the Quiet Count field indicates the number of target beacon transmission times (TBTTs), that is, the beacon interval until the next quiet period begins.

[0099] The Quiet Period field represents the quiet periods, each of which has a duration of a number of beacon intervals. For example, if the Quiet Period field is set to 0, this indicates that no periodic quiet intervals are defined, and if the Quiet Period field is set to 1, this indicates that there are periodic quiet intervals.

[0100] The Quiet Duration field indicates the duration of the quiet period.

[0101] The Quiet Offset field indicates the offset of the quiet period at which the TBTT specified by the Quiet Count field starts, and is expressed in TU. The value of the Quiet Offset field is smaller than one beacon interval. Quiet Offset is a time offset. Normally, quiet time starts immediately after the Beacon, and the stop time is Quiet Duration, but this time can also be delayed, in which case the delayed time is Quiet Offset.

[0102] The target radio frame includes a Quiet Element and a Limited Target Wake Time (rTWT) element corresponding to each of the Quiet Elements, i.e., at least one or more rTWT elements have a corresponding Quiet Element, and the Beacon and Probe Response include one or more Quiet Elements, allowing overlapping quiet intervals to be scheduled, and an AP (e.g., an Enhancements for extremely high throughput (EHT) AP) transmits the Beacon and the Probe Response to realize protection of the rTWT by the Quiet Element and prevent legacy STAs and other STAs not participating in the rTWT session from accessing the channel and interfering with the low-latency transmission service transmitted by the target STA.

During the overlap time, stations are not allowed to access and interfere with the low latency transmission service when there is no low latency service, thereby realizing the protection of the rTWT by the Quiet Element. For example, when a Beacon frame includes a Quiet Element and an rTWT, access of stations (when there is no low latency service) is restricted within the overlap time between the Quiet Element and the time length information or service period of the rTWT. Specifically, taking the target wireless frame as an example, the format of the Quiet Element information is shown in Table 2.
