Description

Technical Field

[0001] The present disclosure relates to the field of mobile communication technologies, and in particular to a signal processing method and device, an electronic device, and a storage medium. Background Art

[0002] With the rapid development of mobile communications, Wireless Fidelity (Wi-Fi) has achieved significant progress in transmission speed and throughput. Current research on Wi-Fi technologies includes topics such as 320MHz bandwidth transmission, aggregation and coordination of multiple frequency bands, and key application scenarios such as video transmission, augmented reality (AR), and virtual reality (VR).

[0003] Specifically, the aggregation and coordination of multiple frequency bands means that devices can communicate simultaneously on 2.4GHz, 5.8GHz, 6GHz, and other frequency bands. For scenarios where devices communicate simultaneously on multiple frequency bands, a new Media Access Control (MAC) mechanism needs to be defined to manage this. Furthermore, the aggregation and coordination of multiple frequency bands is expected to support low-latency transmission.

[0004] In low-latency transmission technology, the restricted target wake time (rTWT) mechanism has been introduced. The rTWT mechanism allows access points (APs) to use enhanced media access protection and resource reservation mechanisms to provide more predictable delays, enabling the AP to reduce worst-case delays and / or jitter, thereby providing more reliable services. Therefore, it is necessary to provide relevant information about the rTWT information element to meet the requirements of low-latency transmission. Summary of the Invention

[0031] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0032] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0033] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.

[0034] The embodiments of the present disclosure provide a signal processing method and device, an electronic device and a storage medium, which are used to provide relevant information of an rTWT information element to meet the requirements of low-latency transmission.

[0035] Among them, the method and the device are based on the same application concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0036] like Figure 1 As shown in , an embodiment of the present disclosure provides a signal processing method, which can optionally be applied to an AP. In a wireless local area network, a Basic Service Set (BSS) can be 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 its AP, and then connected to another Basic Service Set to form an Extended Service Set (ESS). The AP and STA communicate via a communication link.

[0037] The method may include the following steps:

[0038] Step 101: Send a target wireless frame; wherein the target wireless frame includes a restricted target wake-up time rTWT element and a quiet element corresponding to the rTWT element.

[0039] In low-latency transmission scenarios, the real-time data traffic of more applications has strict delay requirements, for example, the average delay or maximum delay is on the order of a few milliseconds to tens of milliseconds, and the applications require real-time data traffic to have extremely small jitter and strong reliability; the rTWT mechanism allows the AP to use enhanced media access protection mechanism and resource reservation mechanism to provide more predictable delay, allowing the AP to reduce the worst-case delay and / or reduce jitter to provide more reliable services; therefore, low-latency services, such as services with an average delay of less than 10 milliseconds, can be transmitted through the rTWT mechanism.

[0040] The AP sends a target wireless frame to the STA. Optionally, the target wireless frame is, for example, a beacon frame, a probe response frame, a multi-link probe response (ML Probe Response) frame, etc.

[0041] When the AP sends a target wireless frame to the STA (target STA), 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 wireless frame carries a Quiet Element, so that the Quiet Period (time information / duration information) in the Quiet Element overlaps with the duration information or service period (SP time) in the rTWT. The overlapping time does not allow the station to access when there is no low-latency service, causing interference to the low-latency transmission service, thereby protecting the rTWT through the Quiet Element; for example, if the Beacon frame contains the Quiet Element and rTWT, the Quiet Element and the duration information or service period in the rTWT will restrict the station (when there is no low-latency service) from accessing during the overlapping time; specifically, taking the target wireless frame as a beacon as an example, the format of the Quiet Element information is shown in Table 1:

[0042] Table 1:

[0043]

[0044]

[0045] The Quiet Count field indicates the number of target beacon transmission times (TBTT), that is, the beacon interval until the next quiet period begins.

[0046] The Quiet Period field indicates the quiet period, which is a number of beacon intervals long. For example, if the Quiet Period field is set to 0, no periodic quiet intervals are defined; if the Quiet Period field is set to 1, periodic quiet intervals are defined.

[0047] The Quiet Duration field indicates the duration of the quiet period, expressed in TU.

[0048] The Quiet Offset field indicates the offset of the quiet period from the TBTT specified in the Quiet Count field, expressed in TUs. The value of the Quiet Offset field is less than one beacon interval. The Quiet Offset is a time offset. Typically, the Quiet period starts immediately after the Beacon, and the Quiet Duration is the Quiet Duration. However, the Quiet Duration can be delayed, in which case the delay is the Quiet Offset.

[0049] The target wireless frame includes a Quiet Element and a restricted target wake-up time rTWT element corresponding to the Quiet Element; that is, at least one or more rTWT elements have a corresponding Quiet Element, and overlapping silent intervals can be scheduled by including one or more Quiet elements in the Beacon and Probe Response. The AP [for example, Enhancements for extremely high throughput (EHT) AP] sends the Beacon and the Probe Response to protect the rTWT through the Quiet Element, preventing legacy STA and other STAs not participating in the rTWT session from accessing the channel and interfering with the low-latency transmission services transmitted by the target STA.

[0050] It should be noted that the target wireless frame includes an rTWT element and a QuietElement corresponding to the rTWT element; wherein, there may be only one rTWT element with a corresponding Quiet Element, or there may be at least two rTWT elements with corresponding Quiet Element; this embodiment of the present disclosure is not limited here.

[0051] It should be understood that in the embodiments of the present disclosure, the AP and (target) STA can be devices supporting single connections or multiple connections. In a multiple connection scenario, the AP and STA can be represented as AP MLD and non-APMLD, respectively. For ease of description, the following description mainly focuses on an example of an AP and a STA communicating under multiple connections in a multiple connection scenario. However, the embodiments of the present disclosure are not limited to this.

[0052] In an embodiment of the present disclosure, an AP sends a target wireless frame to a STA, and the target wireless 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 maximum delay and / or jitter, thereby providing a more reliable service for low-latency transmission services. An embodiment of the present disclosure provides a configuration method and a transmission method for an rTWT information element.

[0053] like Figure 2 As shown in , an embodiment of the present disclosure further provides a signal processing method. Optionally, the method can be applied to an AP. The method may include the following steps:

[0054] Step 201: Send a target wireless frame; wherein, in the target wireless frame, silence elements and rTWT elements are arranged according to the following case 1 and / or case 2.

[0055] Case 1: The first arrangement order of the first silent element in the silent element is the same as the second arrangement order of the first rTWT element in the rTWT element; the first rTWT element is the rTWT element corresponding to the first silent element.

[0056] In case 1, silent elements and rTWT elements appear in pairs in a one-to-one correspondence. For the target wireless frame, all silent elements are sorted separately to obtain a silent element sorting Ra, where a represents the sorting value; all rTWT elements are sorted separately to obtain an rTWT element sorting Rb, where b represents the sorting value; for paired silent elements and rTWT elements, the sorting of silent elements in the silent elements is the first sorting order Ra, and the sorting of rTWT elements in the rTWT elements is the second sorting order Ra, then a=b.

[0057] Case 2: the silence element includes a time offset value; the time offset subfield is carried in the second rTWT element, and the time offset subfield includes the time offset value of the target silence element corresponding to the rTWT element.

[0058] The quiet element includes a time offset value, and the time offset value is unique; as shown in the Quiet Offset field in Table 1 above. The second rTWT element carries a time offset subfield, wherein the time offset subfield includes the time offset value of the target quiet element corresponding to one or at least two of the rTWT elements in the target wireless frame; if the time offset subfield includes the time offset value of the target quiet element corresponding to each of the rTWT elements, the number of time offset values ​​in the time offset subfield is consistent with the number of target quiet elements.

[0059] For example, the target wireless frame includes N rTWT elements, one of which is used as the second rTWT element. In the time offset subfield of the second rTWT element, the time offset value of the target silent element corresponding to each of the N rTWT elements is indicated. In this way, the target silent element corresponding to each rTWT element can be determined based on the time offset value of the target silent element corresponding to each of the N rTWT elements.

[0060] In an optional embodiment, the rTWT element includes at least one of the first indication information and the second indication information;

[0061] Among them, the first indication information indicates that the service corresponding to the target wireless frame includes a low-latency service; the first indication information is the identifier of the low-latency transmission service, which indicates that the rTWT element is used for the transmission of the low-latency service; for example, the AP broadcasts the identifier of the low-latency transmission service.

[0062] The second indication information indicates that the service corresponding to the target wireless frame includes uplink service or downlink service. The service period (Service Period, SP) of the low-latency service is divided into uplink and downlink. One bit can be used for the second indication information, for example, "0" is used to identify uplink service and "1" is used to identify downlink service.

[0063] In an optional embodiment, the access point device includes a single-connection device or a multi-connection device.

[0064] Access point devices can support multi-link communication or single-link communication. Taking multi-link communication as an example, in a wireless communication system, APs and STAs can be multi-link devices (MLDs). MLDs support the ability to send and / or receive messages simultaneously over multiple connections. Therefore, multiple connections can exist between the AP and STA for communication.

[0065] like Figure 3 As shown in , an embodiment of the present disclosure further provides a signal processing method. Optionally, the method can be applied to an AP, and the AP includes a multi-connection device (AP MLD). The method can include step 301 and / or step 302.

[0066] Step 301: Under each communication connection with the site, send a target wireless frame corresponding to the communication connection respectively; wherein the target wireless frame includes a restricted target wake-up time rTWT element and a quiet element corresponding to the rTWT element.

[0067] AP MLD broadcasts the target wireless frame under each communication link of the low-latency service mapping.

[0068] Optionally, the communication connection mentioned in step 301 is a communication connection for transmitting low-latency transmission services; the AP may also not send the target wireless frame in a partial communication connection with the site that does not transmit low-latency transmission services.

[0069] Step 302: Send radio frame information of each communication connection under at least one of the communication connections;

[0070] The wireless frame information includes the target wireless frame and identification information of the target communication connection corresponding to each target wireless frame, and the identification information includes at least one of a connection identifier Link ID and a connection identifier set bitmap LinkIDSet Bitmap.

[0071] The target wireless frame includes a restricted target wake-up time rTWT element and a quiet element corresponding to the rTWT element.

[0072] Optionally, the communication connection mentioned in step 302 is a communication connection for transmitting low-latency transmission services; for some communication connections that do not transmit low-latency transmission services, the AP does not broadcast their wireless frame information.

[0073] AP MLD can broadcast wireless frame information under other communication connections under at least one communication connection between it and the STA; the wireless frame information includes the target wireless frame and the identification information of the target communication connection corresponding to each target wireless frame; the identification information includes at least one of the connection identifier Link ID and the connection identifier set bitmap Link IDSet Bitmap; for example, when the identification information includes Link IDSet Bitmap, the number of rTWT elements appearing is the same as the number set to "1" in link ID Setbitmap, where linkIDsetbitmap can be two bytes.

[0074] like Figure 4 As shown in , an embodiment of the present disclosure further provides a signal processing method. Optionally, the method can be applied to an AP, and the method includes:

[0075] Step 401: determine a target radio frame; wherein the target radio frame includes a restricted target wake-up time rTWT element and a quiet element corresponding to the rTWT element.

[0076] In low-latency transmission scenarios, the real-time data traffic of more applications has strict delay requirements, for example, the average delay or maximum delay is on the order of a few milliseconds to tens of milliseconds, and the applications require real-time data traffic to have extremely small jitter and strong reliability; the rTWT mechanism allows the AP to use enhanced media access protection mechanism and resource reservation mechanism to provide more predictable delay, allowing the AP to reduce the worst-case delay and / or reduce jitter to provide more reliable services; therefore, low-latency services, such as services with an average delay of less than 10 milliseconds, can be transmitted through the rTWT mechanism.

[0077] The AP determines (or generates) a target wireless frame, optionally, a target wireless frame such as a Beacon frame, a Probe Response frame, an ML Probe Response frame, etc. The target wireless 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 services transmitted by the target STA, and to prevent legacy STAs and other STAs that are not participating in the rTWT session from accessing the channel, the Quiet Element is carried in the target wireless frame, so that the Quiet Period (time information / duration information) in the Quiet Element overlaps with the duration information or service period (Service Period, SP) in the rTWT, and the rTWT is protected by the Quiet Element.

[0078] Step 402: Send the target wireless frame.

[0079] The AP sends a target wireless frame to the STA and protects the rTWT element through the Quiet Element, allowing the AP to reduce the maximum delay and / or reduce jitter, providing more reliable services for low-latency transmission services.

[0080] In an optional embodiment, the target wireless frame includes at least one of a Beacon frame, a ProbeResponse frame, an ML ProbeResponse frame, an Association Response frame, and a Reassociation Response frame. It is understood that in addition to this, the target wireless frame may also include other forms, which are not specifically limited in the present embodiment.

[0081] In an embodiment of the present disclosure, the AP sends a target wireless frame to the STA, and the target wireless frame includes an rTWT element and a Quiet Element corresponding to the rTWT element; by protecting the rTWT element through the Quiet Element, the AP reduces the maximum delay and / or reduces the jitter, thereby providing a more reliable service for low-latency transmission services.

[0082] See also Figure 5 The present disclosure also provides a signal processing method for a station device (STA) (or target STA). A STA can be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing device connected to a wireless modem. In a wireless local area network (WLAN), a BSS can consist of an AP and one or more STAs that communicate with the AP. The AP and STAs communicate via a communication link.

[0083] The method comprises:

[0084] Step 501: Receive a target radio frame; wherein the target radio frame includes a restricted target wake-up time rTWT element and a quiet element corresponding to the rTWT element.

[0085] In low-latency transmission scenarios, the real-time data traffic of more applications has strict delay requirements, for example, the average delay or maximum delay is on the order of a few milliseconds to tens of milliseconds, and the applications require real-time data traffic to have extremely small jitter and strong reliability; the rTWT mechanism allows the AP to use enhanced media access protection mechanism and resource reservation mechanism to provide more predictable delay, allowing the AP to reduce the worst-case delay and / or reduce jitter to provide more reliable services; therefore, low-latency services, such as services with an average delay of less than 10 milliseconds, can be transmitted through the rTWT mechanism.

[0086] The STA receives a target wireless frame sent by the AP. Optionally, the target wireless frame is, for example, a Beacon frame, a ProbeResponse frame, or an ML ProbeResponse frame.

[0087] When the AP sends a target wireless frame to the STA (target STA), 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 wireless frame carries a Quiet Element, so that the Quiet Period (time information / duration information) in the Quiet Element overlaps with the duration information or service period (SP time) in the rTWT. During the overlapping period, the station is not allowed to access when there is no low-latency service, causing interference to the low-latency transmission service, thereby protecting the rTWT through the Quiet Element; for example, if the Beacon frame contains the Quiet Element and rTWT, the station (when there is no low-latency service) is restricted from accessing during the overlapping time between the Quiet Element and the duration information or service period in the rTWT; specifically, taking the target wireless frame as a beacon as an example, the format of the Quiet Element information is shown in Table 2:

[0088] Table 2:

[0089]

[0090] The Quiet Count field indicates the number of target beacon transmission times (TBTT), that is, the beacon interval until the next quiet period begins.

[0091] The Quiet Period field indicates the quiet period, which is a number of beacon intervals long. For example, if the Quiet Period field is set to 0, no periodic quiet intervals are defined; if the Quiet Period field is set to 1, periodic quiet intervals are defined.

[0092] The Quiet Duration field indicates the duration of the quiet period.

[0093] The Quiet Offset field indicates the offset of the quiet period from the TBTT specified in the Quiet Count field, expressed in TUs. The value of the Quiet Offset field is less than one beacon interval. The Quiet Offset is a time offset. Typically, the Quiet period starts immediately after the Beacon, and the Quiet Duration is the Quiet Duration. However, the Quiet Duration can be delayed, in which case the delay is the Quiet Offset.

[0094] The target wireless frame includes a Quiet Element and a restricted target wake-up time rTWT element corresponding to the Quiet Element; that is, at least one or more rTWT elements have a corresponding Quiet Element, and overlapping silent intervals can be scheduled by including one or more Quiet elements in the Beacon and Probe Response. The AP [for example, Enhancements for extremely high throughput (EHT) AP] sends the Beacon and the Probe Response to protect the rTWT through the Quiet Element, preventing legacy STA and other STAs not participating in the rTWT session from accessing the channel and interfering with the low-latency transmission services transmitted by the target STA.

[0095] It should be understood that in the embodiments of the present disclosure, the AP and (target) STA can be devices supporting single connections or multiple connections. In a multiple connection scenario, the AP and STA can be represented as AP MLD and non-APMLD, respectively. For ease of description, the following description mainly focuses on an example of an AP and a STA communicating under multiple connections in a multiple connection scenario. However, the embodiments of the present disclosure are not limited to this.

[0096] In an embodiment of the present disclosure, a STA receives a target radio frame sent by an AP, 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 maximum delay and / or jitter, thereby providing a more reliable service for low-latency transmission services. An embodiment of the present disclosure provides a configuration method and a transmission method for an rTWT information element.

[0097] As an optional embodiment, in the target wireless frame, the silence element and the rTWT element are arranged according to the following case 1 and / or case 2.

[0098] Case 1: The first arrangement order of the first silent element in the silent element is the same as the second arrangement order of the first rTWT element in the rTWT element; the first rTWT element is the rTWT element corresponding to the first silent element.

[0099] Silent elements and rTWT elements appear in pairs in a one-to-one correspondence. For the target wireless frame, all silent elements are sorted separately to obtain the silent element sorting Ra, where a represents the sorting value; all rTWT elements are sorted separately to obtain the rTWT element sorting Rb, where b represents the sorting value; for paired silent elements and rTWT elements, the sorting of silent elements in the silent elements is the first sorting order Ra, and the sorting of rTWT elements in the rTWT elements is the second sorting order Ra, then a = b.

[0100] Case 2: the silence element includes a time offset value; the time offset subfield is carried in the second rTWT element, and the time offset subfield includes the time offset value of the target silence element corresponding to the rTWT element.

[0101] The quiet element includes a time offset value, and the time offset value is unique, as shown in the Quiet Offset field in Table 1. The second rTWT element carries a time offset subfield, wherein the time offset subfield includes the time offset value of the target quiet element corresponding to each of the rTWT elements in the target wireless frame, and the number of time offset values ​​in the time offset subfield is consistent with the number of target quiet elements.

[0102] For example, the target wireless frame includes N rTWT elements, one of which is used as the second rTWT element. In the time offset subfield of the second rTWT element, the time offset value of the target silent element corresponding to each of the N rTWT elements is indicated. In this way, the target silent element corresponding to each rTWT element can be determined based on the time offset value of the target silent element corresponding to each of the N rTWT elements.

[0103] As an optional embodiment, the rTWT element includes at least one of the first indication information and the second indication information;

[0104] The rTWT element includes at least one of first indication information and second indication information;

[0105] Among them, the first indication information indicates that the service corresponding to the target wireless frame includes a low-latency service; the first indication information is the identifier of the low-latency transmission service, which indicates that the rTWT element is used for the transmission of the low-latency service; for example, the AP broadcasts the identifier of the low-latency transmission service.

[0106] The second indication information indicates that the service corresponding to the target wireless frame includes uplink service or downlink service. The service period (Service Period, SP) of the low-latency service is divided into uplink and downlink. One bit can be used for the second indication information, for example, "0" is used to identify uplink service and "1" is used to identify downlink service.

[0107] As an optional embodiment, the site device includes a single-connection device or a multi-connection device.

[0108] Station devices can support multi-connection communication or single-connection communication. For example, in a wireless communication system, both the AP and the STA can be MLDs. MLDs support the ability to send and / or receive data simultaneously over multiple connections. Therefore, multiple connections can exist between the AP and the STA for communication.

[0109] As an optional embodiment, when the site device includes a multi-connection device, the receiving of the target wireless frame includes case three and / or case four:

[0110] Case 3: In each communication connection with the access point, a target wireless frame corresponding to the communication connection is received respectively;

[0111] The AP MLD broadcasts the target wireless frame in each communication link of the low-latency service mapping, and the STAMLD (or non-AP MLD) receives the target wireless frame corresponding to each communication link with the access point.

[0112] Case 4: Under at least one of the communication connections, wireless frame information of each of the communication connections is received;

[0113] The wireless frame information includes the target wireless frame and identification information of the target communication connection corresponding to each target wireless frame, and the identification information includes at least one of a connection identifier Link ID and a connection identifier set bitmap LinkIDSet Bitmap.

[0114] The wireless frame information includes the target wireless frame and identification information of the target communication connection corresponding to each target wireless frame, and the identification information includes at least one of a connection identifier Link ID and a connection identifier set bitmap LinkIDSet Bitmap.

[0115] The target wireless frame includes a restricted target wake-up time rTWT element and a quiet element corresponding to the rTWT element.

[0116] AP MLD can broadcast wireless frame information under other communication connections under at least one communication connection between it and STA MLD, and STA MLD receives wireless frame information of each communication connection under at least one of the communication connections; the wireless frame information includes the target wireless frame and the identification information of the target communication connection corresponding to each of the target wireless frame; the identification information includes at least one of the connection identifier Link ID and the connection identifier set bitmap Link IDSet Bitmap; for example, when the identification information includes Link IDSet Bitmap, the number of rTWT elements appearing is the same as the number set to "1" in linkID Setbitmap.

[0117] In an optional embodiment, the target wireless frame includes at least one of a Beacon frame, a ProbeResponse frame, an ML ProbeResponse frame, an Association Response frame, and a Reassociation Response frame. It is understood that in addition to this, the target wireless frame may also include other forms, which are not specifically limited in the present embodiment.

[0118] In an embodiment of the present disclosure, a STA receives a target wireless frame sent by an AP, and the target wireless frame includes an rTWT element and a Quiet Element corresponding to the rTWT element; by protecting the rTWT element through the Quiet Element, the AP reduces the maximum delay and / or reduces the jitter, thereby providing a more reliable service for low-latency transmission services.

[0119] Based on the same principle as the method provided in the embodiment of the present disclosure, the embodiment of the present disclosure also provides an access point device. In a wireless local area network, a BSS can 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 its AP, and then connected to another basic service set to form an extended service set (ESS). The AP and the STA communicate through a communication connection. Figure 6 As shown, the access point device includes:

[0120] The sending module 601 is configured to send a target radio frame, wherein the target radio frame includes a restricted target wake-up time rTWT element and a quiet element corresponding to the rTWT element.

[0121] In low-latency transmission scenarios, the real-time data traffic of more applications has strict delay requirements, for example, the average delay or maximum delay is on the order of a few milliseconds to tens of milliseconds, and the applications require real-time data traffic to have extremely small jitter and strong reliability; the rTWT mechanism allows the AP to use enhanced media access protection mechanism and resource reservation mechanism to provide more predictable delay, allowing the AP to reduce the worst-case delay and / or reduce jitter to provide more reliable services; therefore, low-latency services, such as services with an average delay of less than 10 milliseconds, can be transmitted through the rTWT mechanism.

[0122] The AP sends a target wireless frame to the STA. Optionally, the target wireless frame is, for example, a Beacon frame, a Probe Response frame, an ML Probe Response frame, etc.

[0123] When the AP sends a target wireless frame to the STA (target STA), 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 wireless frame carries a Quiet Element, so that the Quiet Period (time information / duration information) in the Quiet Element overlaps with the duration information or service period (SP time) in the rTWT. During the overlapping period, the station is not allowed to access when there is no low-latency service, causing interference to the low-latency transmission service, thereby protecting the rTWT through the Quiet Element; for example, if the Beacon frame contains the Quiet Element and rTWT, the station (when there is no low-latency service) is restricted from accessing during the overlapping time between the Quiet Element and the duration information or service period in the rTWT; specifically, taking the target wireless frame as a beacon as an example, the format of the Quiet Element information is shown in Table 1:

[0124] Table 1:

[0125]

[0126] The Quiet Count field indicates the number of target beacon transmission times (TBTT), that is, the beacon interval until the next quiet period begins.

[0127] The Quiet Period field indicates the quiet period, which is a number of beacon intervals long. For example, if the Quiet Period field is set to 0, no periodic quiet intervals are defined; if the Quiet Period field is set to 1, periodic quiet intervals are defined.

[0128] The Quiet Duration field indicates the duration of the quiet period.

[0129] The Quiet Offset field indicates the offset of the quiet period from the TBTT specified in the Quiet Count field, expressed in TUs. The value of the Quiet Offset field is less than one beacon interval. The Quiet Offset is a time offset. Typically, the Quiet period starts immediately after the Beacon, and the Quiet Duration is the Quiet Duration. However, the Quiet Duration can be delayed, in which case the delay is the Quiet Offset.

[0130] The target wireless frame includes a Quiet Element and a restricted target wake-up time rTWT element corresponding to the Quiet Element; that is, at least one or more rTWT elements have a corresponding Quiet Element, and overlapping silent intervals can be scheduled by including one or more Quiet elements in the Beacon and Probe Response. The AP [for example, Enhancements for extremely high throughput (EHT) AP] sends the Beacon and the Probe Response to protect the rTWT through the Quiet Element, preventing legacy STA and other STAs not participating in the rTWT session from accessing the channel and interfering with the low-latency transmission services transmitted by the target STA.

[0131] It should be understood that in the embodiments of the present disclosure, the AP and (target) STA can be devices supporting single connections or multiple connections. In a multiple connection scenario, the AP and STA can be represented as AP MLD and non-APMLD, respectively.
