For another example, the number of description objects is not limited by the ordinal number and can be one or more. Taking "first device" as an example, the number of "devices" can be one or more. In addition, the objects modified by different prefixes can be the same or different. For example, if the description object is "device", then the "first device" and the "second device" can be the same device or different devices, and their types can be the same or different; for another example, if the description object is "information", then the "first information" and the "second information" can be the same information or different information, and their contents can be the same or different.

[0130] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0131] As shown in FIG1 , a communication system 100 includes a first access point (AP) device 101 , a second AP device 102 , and a third AP device 103 .

[0132] In some embodiments, the first AP device 101, the second AP device 102, and the third AP device 103 can be access points for mobile terminals to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the first AP device 101, the second AP device 102, and the third AP device 103 can be terminal devices or network devices with wireless fidelity chips. Optionally, the first AP device 101, the second AP device 102, and the third AP device 103 can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a, as well as support the next generation 802.11 protocol, but are not limited to these.

[0133] Among them, each AP device can perform low-latency service transmission with the associated STA device within the service time of the scheduled R-TWT information.

[0134] In some embodiments, the STA device in the embodiments of the present disclosure may be a device including a wireless communication chip supporting WiFi communication functions, a wireless sensor, or a wireless communication terminal. Optionally, the wireless communication terminal may be, for example, a mobile phone, a wearable device, an IoT device supporting WiFi communication functions, a car with WiFi communication functions, a smart car, a tablet computer, a computer with wireless transceiver functions, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in smart grids, a wireless terminal device used in transportation safety, a wireless terminal device used in smart cities, or a wireless terminal device used in smart homes, but is not limited thereto.

[0135] Specifically, the STA device can be a terminal device or network device with a Wireless Fidelity (WiFi) chip. Optionally, the STA device can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a, as well as support the next generation 802.11 protocol, but is not limited thereto.

[0136] Optionally, in an embodiment of the present disclosure, the AP device and the STA device may be devices supporting multiple connections, for example, they may be respectively represented as an access point device supporting multiple connections (Access Point Multi-Link Device, AP MLD) and a site device supporting multiple connections (Non-Access Point Multi-Link Device, Non-AP MLD); AP MLD may represent an access point supporting multiple connection communication functions, and non-AP MLD may represent a site supporting multiple connection communication functions.

[0137] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0138] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0139] The various embodiments of the present disclosure may be applied to wireless local area networks (WLANs), such as IEEE 802.11 system standards, such as 802.11a / b / g, 802.11n, 802.11ac, 802.11ax, or their successors, such as 802.11be, also known as WiFi7 or the extremely high throughput (EHT) standard, or even later generations. Alternatively, the various embodiments of the present disclosure may also be applied to wireless local area network systems, such as Internet of Things (IoT) networks or Vehicle to X (V2X) networks. Of course, the embodiments of the present disclosure can also be applied to other possible communication systems, such as long term evolution (LTE) system, LTE frequency division duplex (FDD) system, LTE time division duplex (TDD) system, universal mobile telecommunication system (UMTS), world-wide interoperability for microwave access (WiMAX) communication system, and future fifth generation (5G) communication system.

[0140] In a WLAN, the Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS consists of associated devices within a specific coverage area. One such association is for STA devices to communicate directly with each other within an ad hoc network, known as an Independent Basic Service Set (IBSS). A more common BSS consists of a single central station dedicated to managing the BSS, called an AP, and includes at least one STA device associated with the AP.

[0141] To reduce device power consumption, the 802.11ax protocol introduces a Target Wake Time (TWT) energy-saving mechanism. This mechanism allows APs and STAs within a BSS to negotiate a communication schedule during specific service hours and remain dormant during other times, saving energy. To ensure low-latency service communication, 802.11be introduces a Restricted Target Wake Time (R-TWT) protocol. During the R-TWT Service Period (SP), only low-latency services communicate; other communication services are suspended or postponed.

[0142] In 802.11be, R-TWT is defined from the perspective of transmitting low-latency services within a single BSS. R-TWT provides a protection mechanism whereby STAs within a single BSS suspend or terminate their transmission opportunities or other non-low-latency service transmissions before joining the corresponding SP scheduled by R-TWT, ensuring the effective transmission of low-latency services.

[0143] With the diversification of communication service demands and the development trend of high-frequency bands, WLAN equipment deployment is becoming more and more dense, and the phenomenon of overlapping basic service sets (OBSS) is becoming more and more common. Compared with 802.11be, UHR aims to improve tail delay and jitter, including OBSS scenarios. Since the existing R-TWT mechanism is based on a single BSS, only other sites in this BSS postpone or terminate non-delay services within the R-TWT SP to ensure the transmission of low-latency services. However, in the scenario where the scheduling members of R-TWT are located in the OBSS, when the service times of the R-TWT information corresponding to multiple BSSs overlap, the STA devices in the OBSS may be interfered with by other AP devices when transmitting low-latency services. As shown in Figure 2, Figure 2 is a schematic diagram of the network architecture provided by an embodiment of the present disclosure. In Figure 2, the basic service set where AP1 is located is BSS1, the basic service set where AP2 is located is BSS2, and the basic service set where AP3 is located is BSS3.

[0144] AP1 can establish associations and communicate with STA1-1, STA1-2, and STA1-3 within BSS1. AP2 can establish associations and communicate with STA2-1 and STA2-2 within BSS2. STA1-3 is located in OBSS2, formed by BSS1 and BSS3, and STA1-1 is located in OBSS1, formed by BSS1 and BSS2. STA1-1 may experience interference from AP2 when communicating with AP1, and STA1-3 may experience interference from AP3 when communicating with AP1.

[0145] On the other hand, only STA devices within a BSS know the R-TWT information scheduled by the associated AP device. AP devices are unaware of R-TWT information scheduled by other BSSs or neighboring AP devices. This can lead to transmission overlap, collisions, retransmissions, hidden node issues, and other issues within different BSSs, resulting in higher latency. Although R-TWT scheduling within a single BSS can improve the efficiency and reliability of low-latency service transmission, in future, more densely deployed WLAN device scenarios, the transmission efficiency of a single BSS will significantly decrease as low-latency service transmission in OBSS scenarios occupies the medium. Multiple AP devices can coordinate the transmission of low-latency services within multiple BSSs, especially the low-latency service transmission of STA devices in OBSS scenarios, to improve the efficiency of low-latency service transmission.

[0146] In this regard, in order to improve the coordination mechanism of the above-mentioned R-TWT information, the technical solutions in the embodiments of the present disclosure will be further described clearly and completely in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present disclosure.

[0147] FIG3 is one of the interactive schematic diagrams of the communication method according to an embodiment of the present disclosure. As shown in FIG3 , the method includes:

[0148] In step S31, the second AP device sends a first wireless frame to the first AP device. The first wireless frame includes a second R-TWT message and at least one third R-TWT message. The second R-TWT message is scheduled by the second AP device, and each third R-TWT message is scheduled by an AP device other than the second AP device.

[0149] In some embodiments, when the second AP device sends a first wireless frame to the first AP device, it may carry first parameter information in the first wireless frame, and the first parameter information is used by the first AP device to determine whether to adjust the first R-TWT information scheduled by the first AP device.

[0150] The first parameter information includes the second R-TWT information scheduled by the second AP device and at least one third R-TWT information.

[0151] Each third R-TWT information is scheduled by an AP device other than the second AP device.

[0152] Among them, each third R-TWT information is obtained by the second AP device from other AP devices.

[0153] That is, the second AP device sends a first wireless frame, which includes second R-TWT information and at least one third R-TWT information, and is used by the first AP device to determine whether to adjust the first R-TWT information scheduled by the first AP device based on the second AP device information and the third R-TWT information.

[0154] In some embodiments, the first wireless frame includes multiple broadcast target wake-up time parameter set (Broadcast TWT Parameter Set) fields, and each broadcast target wake-up time parameter set field includes the second R-TWT information or the third R-TWT information.

[0155] That is, the first wireless frame includes multiple broadcast target wake-up time parameter set fields, one broadcast target wake-up time parameter set field includes the second R-TWT, and each of the other broadcast target wake-up time parameter set fields includes a third R-TWT information.

[0156] Optionally, the first wireless frame includes a target wake-up time parameter information (TWT Parameter Information) field, and the target wake-up time parameter information field includes multiple broadcast target wake-up time parameter set (Broadcast TWT Parameter Set) fields.

[0157] Optionally, the first wireless frame includes a target wake-up time element (TWT element) field, a target wake-up time parameter information (TWT Parameter Information) field, and the target wake-up time parameter information field includes multiple broadcast target wake-up time parameter set (Broadcast TWT Parameter Set) fields.

[0158] In some embodiments, the first radio frame includes multiple broadcast target wake-up time parameter set fields, each broadcast target wake-up time parameter set field includes the second R-TWT information or one third R-TWT information.

[0159] Optionally, each broadcast target wake-up time parameter set domain may include a first indication domain, which indicates through a third value that the R-TWT information included in the broadcast target wake-up time parameter set domain is the second R-TWT information, and indicates through a fourth value that the R-TWT information included in the corresponding broadcast target wake-up time parameter set domain is the third R-TWT information.

[0160] That is, for each broadcast target wake-up time parameter set domain, the first indication domain of the broadcast target wake-up time parameter set domain indicates through the third value that the R-TWT information included in the broadcast target wake-up time parameter set domain is scheduled by the second AP device, and indicates through the fourth value that the R-TWT information included in the broadcast target wake-up time parameter set domain is scheduled by an AP device other than the second AP device, that is, it indicates that the R-TWT information included in the broadcast target wake-up time parameter set domain is not scheduled by the second AP device.

[0161] The third value and the fourth value are different values. For example, the fourth value may be 5 and the third value may be 6, etc., and there is no limitation here.

[0162] Optionally, each broadcast target wake-up time parameter set domain includes a second indication domain, and the second indication domain is used to indicate the basic service set BSS where the AP device that schedules the R-TWT information included in the broadcast target wake-up time parameter set domain is located.

[0163] Among them, the first indication field in each broadcast target wake-up time parameter set field may include the identification information of the BSS where the corresponding AP device is located (such as BSSID) to directly indicate the BSS where the AP device that schedules the R-TWT information included in the broadcast target wake-up time parameter set field is located.

[0164] Among them, the first indication field in each broadcast target wake-up time parameter set field may include the MAC address, device identifier, and other related information of the corresponding AP device that can be used to uniquely identify the AP device, and is used to indirectly indicate the BSS where the corresponding AP device is located.

[0165] Optionally, each broadcast target wake-up time parameter set domain includes a second identification bit, and the second identification bit indicates through a fifth value that the R-TWT information included in the broadcast target wake-up time parameter set domain supports adjustment; the second identification bit indicates through a sixth value that the R-TWT information included in the broadcast target wake-up time parameter set domain does not support adjustment.

[0166] For example, each broadcast target wake-up time parameter set domain includes a second identification bit, and the second identification bit indicates through the fifth value that when the service time of the R-TWT information included in the broadcast target wake-up time parameter set domain overlaps with the service time of other R-TWT information, the R-TWT information included in the broadcast target wake-up time parameter set domain supports adjustment, and is also used to indicate that when the service time of the R-TWT information included in the broadcast target wake-up time parameter set domain overlaps with the service time of other R-TWT information, the other R-TWT information whose service time overlaps with it shall be executed first. The second identification bit indicates through the sixth value that regardless of whether the service time of the R-TWT information included in the broadcast target wake-up time parameter set domain overlaps with the service time of other R-TWT information, the R-TWT information included in the broadcast target wake-up time parameter set domain always does not support adjustment.

[0167] Among them, the second identification bit of each broadcast target wake-up time parameter set domain can specifically indicate through the fifth value that the R-TWT information included in the broadcast target wake-up time parameter set domain respects other R-TWT information whose service time overlaps with it, so as to further indicate that when the service time of the R-TWT information included in the broadcast target wake-up time parameter set domain overlaps with the service time of other R-TWT information, the R-TWT information included in the broadcast target wake-up time parameter set domain supports adjustment (supports change).

[0168] Among them, the second identification bit of each broadcast target wake-up time parameter set domain can specifically indicate through the fifth value that the R-TWT information included in the broadcast target wake-up time parameter set domain does not respect other R-TWT information whose service time overlaps with it, so as to further indicate that when the service time of the R-TWT information included in the broadcast target wake-up time parameter set domain overlaps with the service time of other R-TWT information, the R-TWT information included in the broadcast target wake-up time parameter set domain does not support adjustment (does not support change).

[0169] The fifth value and the sixth value are different. For example, the fifth value may be 1 and the sixth value may be 0, which is not limited here.

[0170] Optionally, each broadcast target wake-up time parameter set field in the first wireless frame may include only one of the first indication field, the second indication field or the second identification bit, or may include any one or more of the first indication field, the second indication field, or the second identification bit, without limitation here.

[0171] For example, for each broadcast target wake-up time parameter set domain of the first wireless frame, the broadcast target wake-up time parameter set domain includes a first indication domain. When the identification value of the first indication domain is the fourth value, the broadcast target wake-up time parameter set domain includes a second indication domain, which is used to indicate the BSS where the AP device that schedules the R-TWT information of the broadcast target wake-up time is located.

[0172] That is to say, for each broadcast target wake-up time parameter set domain of the first wireless frame, the broadcast target wake-up time parameter set domain includes a first indication domain. When the first indication domain is used to indicate that the R-TWT information included in the broadcast target wake-up time parameter set domain is scheduled by an AP device other than the second AP device, the broadcast target wake-up time parameter set domain also includes a second indication domain, which is used to indicate the BSS where the AP device that schedules the R-TWT information of the broadcast target wake-up time is located.

[0173] Among them, each broadcast target wake-up time parameter set domain includes a second identification bit, and the second identification bit indicates through the fifth value that the R-TWT information included in the broadcast target wake-up time parameter set domain supports adjustment; the second identification bit indicates through the sixth value that the R-TWT information included in the broadcast target wake-up time parameter set domain does not support adjustment.

[0174] In some embodiments, the first wireless frame includes multiple broadcast target wake-up time parameter set fields, each broadcast target wake-up time parameter set field includes a request type (Request Type) field, the request type field includes a broadcast target wake-up time recommendation (Broadcast TWT Recommendation) subfield, and the broadcast target wake-up time recommendation subfield includes a first indication field.

[0175] Optionally, the first indication field may be a broadcast target wake-up time recommendation subfield.

[0176] Optionally, the first indication field may be one or more bits of a broadcast target wake-up time recommendation subfield.

[0177] In some embodiments, the first radio frame includes a plurality of broadcast target wake time parameter set fields, each broadcast target wake time parameter set field includes a request type (Request Type) field, and the request type field includes a second identification bit.

[0178] Optionally, the second identification bit may be any information field in the request type field, or may be at least one bit in the request type field.

[0179] In some embodiments, the first radio frame includes a plurality of broadcast target wake time parameter set fields, each broadcast target wake time parameter set field including a second indication field.

[0180] Optionally, the second indication field may be any information field in the broadcast target wake-up time parameter set field, or may be at least one bit in the request type field.

[0181] In step S32, the first AP device determines whether the service time of at least one of the second R-TWT information and the third R-TWT information overlaps with the service time of the first R-TWT information.

[0182] In some embodiments, the first AP device determines whether a service time of at least one of the second R-TWT information and the third R-TWT information overlaps with a service time of the first R-TWT information.

[0183] If the service time of at least one of the second and third R-TWT information overlaps with the service time of the first R-TWT information, the first AP device executes step S32-1. If the service time of at least one of the second and third R-TWT information overlaps with the service time of the first R-TWT information, the first AP device executes step S32-2.

[0184] Step S32-1: The first AP device does not adjust the first R-TWT information scheduled by the first AP device.

[0185] When the first AP device determines that there is no R-TWT information in the second R-TWT information and the third R-TWT information whose service time overlaps with the service time of the first R-TWT information, it means that when the first AP device transmits a low-latency service within the service time of the first R-TWT information, it will not interfere with the low-latency service transmission process of other AP devices. In this case, the first AP device may not adjust the first R-TWT information.

[0186] Step S32-2: When the first R-TWT information supports adjustment, the first R-TWT information is adjusted; when the first R-TWT information does not support adjustment, the first R-TWT information is not adjusted.

[0187] When the first AP device determines that the service time of at least one R-TWT information in the second R-TWT information and the third R-TWT information overlaps with the service time of the first R-TWT information, it means that when the first AP device transmits low-latency services within the service time of the first R-TWT information, it may interfere with the low-latency service transmission process of other AP devices.

[0188] In this case, when the first R-TWT information supports adjustment, the first AP device may adjust the first R-TWT information. When the first R-TWT information does not support adjustment, the first AP device does not adjust the first R-TWT information.

[0189] Among them, when the first R-TWT information supports adjustment, the first AP device adjusts the first R-TWT information by one or more methods such as shortening or extending the service time, changing the start time or end time of the service time, shortening or extending the service period, etc., and the adjusted R-TWT information.

[0190] Among them, the first AP device can perform low-latency service transmission within the service time of the adjusted R-TWT information.

[0191] Among them, the service time of the adjusted R-TWT information does not overlap with the service time of the second R-TWT information, nor does it overlap with the service time of the third R-TWT information.

[0192] The communication method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, any one of step S31 or step 32 (including step S32-1 and step S32-2) can be implemented as an independent embodiment, and steps S31-step 32 (including step S32-1 and step S32-2) can be implemented as an independent embodiment, but are not limited thereto.

[0193] FIG4 is a second interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG4 , the method includes:

[0194] In step S41, the third AP device sends a second wireless frame to the first AP device. The second wireless frame includes a first identification bit, which is used to indicate whether the scheduling members of the fourth R-TWT information scheduled by the third AP device include a STA device located in the OBSS.

[0195] In some embodiments, when the third AP device sends a second wireless frame to the first AP device, it may carry first parameter information in the second wireless frame, and the first parameter information is used by the first AP device to determine whether to adjust the first R-TWT information scheduled by the first AP device.

[0196] Among them, the first parameter information includes a first identification bit, and the first identification bit is used to indicate whether the scheduling members of the fourth R-TWT information include a STA device located in the OBSS.

[0197] Among them, the fourth R-TWT information is scheduled by the third AP device.

[0198] That is, the third AP device sends a second wireless frame, and the second wireless frame includes a first identification bit, and the first identification bit is used to indicate whether the scheduling members of the fourth R-TWT information include a STA device located in the OBSS.

[0199] Among them, the first identification bit indicates through the first value that the scheduling members of the fourth R-TWT information include STA devices located in the OBSS, and indicates through the second value that the scheduling members of the fourth R-TWT information do not include STA devices located in the OBSS.

[0200] The first value and the second value are different. For example, the first value may be 1 and the second value may be 0, which is not limited here.

[0201] Optionally, the second wireless frame includes fourth R-TWT information of the third AP device and at least one fifth R-TWT information, the fourth R-TWT information is scheduled by the third AP device, and each fifth R-TWT information is scheduled for an AP device other than the third AP device.

[0202] Among them, the fourth R-TWT information and the fifth R-TWT information may belong to the first parameter information carried by the second wireless frame.

[0203] The second wireless frame includes multiple broadcast target wake-up time parameter set fields, and each broadcast target wake-up time parameter set field includes the fourth R-TWT information or the fifth R-TWT information.

[0204] Optionally, the second radio frame includes a target wake-up time parameter information field, and the target wake-up time parameter information field includes multiple broadcast target wake-up time parameter set fields.

[0205] Optionally, the first radio frame includes a target wake-up time element field and a target wake-up time parameter information field, and the target wake-up time parameter information field includes multiple broadcast target wake-up time parameter set fields.

[0206] Optionally, the broadcast target wake-up time parameter set field of the fourth R-TWT information includes a broadcast target wake-up time information (Broadcast TWT Info) field, and the broadcast target wake-up time information field includes a first identification bit, indicating through the first value that the scheduling members of the fourth R-TWT information include STA devices located in the OBSS, and indicating through the second value that the scheduling members of the fourth R-TWT information do not include STA devices located in the OBSS.

[0207] Optionally, the broadcast target wake-up time parameter set field of the fourth R-TWT information includes a broadcast target wake-up time information (Broadcast TWT Info) field, and the broadcast target wake-up time information field includes a first identification bit, indicating through the first value that the scheduling members of the fourth R-TWT information include STA devices located in the OBSS, and indicating through the second value that the scheduling members of the fourth R-TWT information do not include STA devices located in the OBSS.

[0208] In some embodiments, the third AP device may receive a third message frame sent by at least one fourth AP device, and the third message frame sent by each fourth AP device includes the R-TWT information scheduled by the corresponding fourth AP device, and the R-TWT information of other AP devices except the corresponding fourth AP device.

[0209] For each third message frame, the third message frame includes multiple broadcast target wake-up time parameter set fields, and each broadcast target wake-up time parameter set field includes at least one of the following:

[0210] The fourth indication field indicates, through the third value, that the R-TWT information included in the broadcast target wake-up time parameter set field is the second R-TWT information scheduled by the corresponding fourth AP device, and indicates, through the fourth value, that the R-TWT information included in the corresponding broadcast target wake-up time parameter set field is the R-TWT information scheduled by other AP devices;

[0211] The fifth indication field is used to indicate the basic service set BSS where the AP device that schedules the broadcast of the R-TWT information included in the target wake-up time parameter set field is located;

[0212] The third flag bit indicates through the fifth value that the R-TWT information included in the broadcast target wake-up time parameter set domain supports adjustment; the third flag bit indicates through the sixth value that the R-TWT information included in the broadcast target wake-up time parameter set domain does not support adjustment.

[0213] Among them, other optional implementation methods related to the fourth indication field can refer to the relevant description of the aforementioned first indication field, other optional implementation methods related to the fifth indication field can refer to the relevant description of the aforementioned second indication field, and other optional implementation methods related to the third identification bit can refer to the relevant description of the aforementioned second identification bit, which will not be repeated here.

[0214] Among them, the third AP device can determine whether the BSS corresponding to each R-TWT information received by the third AP device forms a first OBSS with the BSS where the third AP device is located based on the content of each received third wireless frame. If the BSS corresponding to each received R-TWT information forms a first OBSS with the BSS where the third AP device is located, the third AP device further determines whether the first OBSS includes the scheduling members of the fourth R-TWT information scheduled by the third AP device, that is, determines whether the scheduling members of the fourth R-TWT information include the STA device located in the first OBSS.

[0215] When the BSS corresponding to each received R-TWT information forms a first OBSS with the BSS where the third AP device is located, the third AP device can send a second wireless frame, and the second wireless frame indicates through the first identification bit whether the scheduling members of the fourth R-TWT information scheduled by the third AP device include STA devices located in the OBSS.

[0216] In some embodiments, the first parameter information carried by the second wireless frame also includes a third indication field, and the third indication field is used to indicate the BSS that forms the first OBSS with the BSS where the third AP device is located, and the first OBSS includes the scheduling members of the fourth R-TWT information.

[0217] As an example, if the BSS where AP1 is located forms an OBSS with the BSS where the third AP device is located, and the formed OBSS includes the STA device scheduled by the fourth R-TWT information, the third indication field is used to indicate the BSS where AP1 is located.

[0218] Optionally, the second wireless frame includes multiple broadcast target wake-up time parameter set fields, including the broadcast target wake-up time parameter set field of the fourth R-TWT information including a broadcast target wake-up time information (Broadcast TWT Info) field, the broadcast target wake-up time information field including a third indication field for indicating the BSS that forms the first OBSS with the BSS where the third AP device is located, and the first OBSS includes the scheduling members of the fourth R-TWT information.

[0219] The third indication field may include identification information (such as BSSID) of the BSS that forms the first OBSS with the BSS where the third AP device is located, so as to directly indicate the BSS that forms the first OBSS with the BSS where the third AP device is located.

[0220] Among them, the third indication field may include the MAC address, device identifier and other relevant information of the AP device corresponding to the BSS that forms the first OBSS with the BSS where the third AP device is located, which can be used to uniquely identify the AP device, and is used to indirectly indicate the BSS that forms the first OBSS with the BSS where the third AP device is located.

[0221] Step S42: The first AP device determines whether the first BSS where the first AP device is located and the second BSS where the third AP device is located form a second OBSS.

[0222] In some embodiments, the first AP device may determine, based on the first parameter information, whether the BSS where the first AP device is located and the BSS where the third AP device is located form a second OBSS.

[0223] If the first AP device determines that the first BSS and the second BSS do not form a second OBSS, it means that when the first AP device performs low-latency service transmission within the service time of the first R-TWT information, it will not interfere with the low-latency service transmission process of the third AP device within the service time of the fourth R-TWT information.

[0224] In this case, the first AP device executes step S46, that is, the first AP device does not adjust the first R-TWT information.

[0225] If the first AP device determines that the first BSS and the second BSS form a second OBSS, it means that when the first AP device performs low-latency service transmission within the service time of the first R-TWT information, it may interfere with the low-latency service transmission process of the third AP device within the service time of the fourth R-TWT information.

[0226] In this case, the first AP device may determine whether to adjust the first R-TWT information according to whether the scheduling members of the fourth R-TWT information include the first STA device located in the second OBSS.

[0227] The first STA device is a STA device located in the second OBSS.

[0228] Among them, the fourth R-TWT information is scheduled by the third AP device.

[0229] Step S43: The first AP device determines whether the scheduling members of the fourth R-TWT information include the first STA device located in the second OBSS.

[0230] In some embodiments, if the first AP device determines that the scheduling members of the fourth R-TWT information do not include the first STA device located in the second OBSS, it means that when the first AP device performs low-latency service transmission within the service time of the first R-TWT information, it will not interfere with the low-latency service transmission process of the third AP device within the service time of the fourth R-TWT information.

[0231] In this case, the first AP device executes step S46, that is, the first AP device does not adjust the first R-TWT information.

[0232] The first STA device is a STA device located in the second OBSS.

[0233] Among them, the fourth R-TWT information is scheduled by the third AP device.

[0234] If the first AP device determines that the scheduling members of the fourth R-TWT information include the first STA device located in the second OBSS, it means that when the first AP device performs low-latency service transmission within the service time of the first R-TWT information or performs communication service transmission at other times, it may interfere with the low-latency service transmission process performed by the third AP device during the service time of the fourth R-TWT information and the first STA device.

[0235] In this case, the first AP device can determine whether to adjust the first R-TWT information based on whether the service time of the first R-TWT information overlaps with the service time of the fourth R-TWT information. In addition, the first AP device does not transmit communication services during the service time of the fourth R-TWT information to avoid interference with the low-latency service transmission process performed by the third AP device during the service time of the fourth R-TWT information and the first STA device when the first AP device transmits communication services during the service time of the fourth R-TWT information.

[0236] In step S44 , the first AP device determines whether the service time of the first R-TWT information and the service time of the fourth R-TWT information overlap.

[0237] In some embodiments, if the first AP device determines that the service time of the first R-TWT information and the service time of the fourth R-TWT information do not overlap, it means that the first R-TWT information does not require adjustment.

[0238] In this case, the first AP device executes step S46, that is, the first AP device does not adjust the first R-TWT information.

[0239] If the first AP device determines that the service time of the first R-TWT information overlaps with the service time of the fourth R-TWT information, it may determine whether to adjust the first R-TWT information according to whether the first R-TWT information supports adjustment.

[0240] Step S45: When the first R-TWT information supports adjustment, the first AP device adjusts the first R-TWT information; when the first R-TWT information does not support adjustment, the first AP device does not adjust the first R-TWT information.

[0241] In some embodiments, the first AP device adjusts the first R-TWT information if the first R-TWT information supports adjustment, and does not adjust the first R-TWT information if the first R-TWT information does not support adjustment.

[0242] When the first R-TWT information supports adjustment, the first AP device can adjust the first R-TWT information by one or more methods such as shortening or extending the service time, changing the start time or end time of the service time, shortening or extending the service period, etc., and the adjusted R-TWT information.

[0243] Among them, the first AP device can perform low-latency service transmission within the service time of the adjusted R-TWT information.

[0244] Among them, the service time of the adjusted R-TWT information does not overlap with the service time of the fourth R-TWT information.

[0245] Step S46: The first AP device does not adjust the first R-TWT information scheduled by the first AP device.

[0268] Optionally, each broadcast target wake-up time parameter set domain may include a first indication domain, which indicates through a third value that the R-TWT information included in the broadcast target wake-up time parameter set domain is the second R-TWT information, and indicates through a fourth value that the R-TWT information included in the corresponding broadcast target wake-up time parameter set domain is the third R-TWT information.

[0270] The third value and the fourth value are different values. For example, the fourth value may be 5 and the third value may be 6, etc., and there is no limitation here.

[0271] Optionally, each broadcast target wake-up time parameter set domain includes a second indication domain, and the second indication domain is used to indicate the basic service set BSS where the AP device that schedules the R-TWT information included in the broadcast target wake-up time parameter set domain is located.
