[0166] In some embodiments, the access point device 102 can be an access point for a mobile terminal 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 AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.

[0167] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a site supporting multi-connection communication functions.

[0168] 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.

[0169] 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.

[0170] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as those using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS network consists of station devices with some association within a specific coverage area. One scenario of association is that stations communicate directly with each other in an ad hoc network, which is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central station dedicated to managing the BSS, called an access point, and all other STAs in the network are associated with it. Other stations in the BSS network that are not the central station are called terminals, also called non-AP STAs. Terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, and other factors, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.

[0171] FIG2 is an interactive diagram of a target wake-up time (TWT) scheduling processing method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0172] In step 201, the site device 101 determines a first wireless frame; wherein the first wireless frame includes first identification information, and the first identification information indicates that the site device intends to perform at least one of the following processing operations on part or all of the TWT scheduling: suspending the TWT scheduling, not suspending the TWT scheduling; the TWT scheduling includes R-TWT scheduling and / or broadcast TWT scheduling.

[0173] In the TWT mechanism, a station device (STA) 101 and an access point device (AP) 102 establish a TWT schedule through negotiation, determining the sleep and wake-up time and frequency of the station device 101. When the target wake-up start time arrives, the station device 101 wakes up and communicates within the corresponding service period (SP), and remains dormant at other times to reduce device energy consumption. In addition, TWT technology can also enable the AP to provide higher quality services to multiple STAs, minimize contention or overlap, and improve spectrum efficiency while reducing Wi-Fi network power consumption.

[0174] In the embodiment of the present disclosure, the TWT scheduling includes restricted target wake time (R-TWT) scheduling and / or (Broadcast) broadcast TWT scheduling. Specifically, compared with broadcast TWT scheduling, the TWT scheduling type also includes unicast (Individual) TWT.

[0175] Regarding R-TWT scheduling, 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. In order to further ensure the communication of low latency services, R-TWT is proposed based on the technology of TWT. The R-TWT mechanism allows APs to use enhanced media access protection mechanisms and resource reservation mechanisms to provide more predictable delays to distinguish delay-sensitive traffic from other types of traffic, allowing APs to reduce the worst-case delay and / or reduce jitter to provide more reliable services.

[0176] Specifically, R-TWT is used to serve low-latency services, such as services with an average delay of less than 10 milliseconds. Within the R-TWT SP, only services marked as low-latency services communicate, and other communication services are suspended or postponed during this stage to ensure the transmission of low-latency services.

[0177] The site device 101 determines a first wireless frame and carries first identification information in the first wireless frame. The first identification information identifies that the site device intends to perform at least one of the following processing operations on part or all of the TWT scheduling: suspend the TWT scheduling, and do not suspend the TWT scheduling.

[0178] The first identification information may be used to identify the processing operations performed by the site device 101 on one or more TWT schedules; the processing operations performed on different TWT schedules may be different; for example, the site device 101 is a member of Broadcast TWT schedule 1 and a member of R-TWT schedule 2, and the site device 101 intends to suspend Broadcast TWT schedule 1 but not R-TWT schedule 2;

[0179] For another example, the site device 101 is a member of Broadcast TWT Schedule 1 and a member of Broadcast TWT Schedule 2, and the site device 101 intends to suspend Broadcast TWT Schedule 1 but not Broadcast TWT Schedule 2;

[0180] Alternatively, the site device 101 is a member of R-TWT scheduling 1, a member of R-TWT scheduling 2, and a member of Broadcast TWT scheduling 3, and the site device 101 intends to suspend R-TWT scheduling 1 but not to suspend R-TWT scheduling 2 and Broadcast TWT scheduling 3.

[0181] In this way, the site device 101 can flexibly control whether each TWT schedule it participates in is suspended, without suspending all TWT schedules at the same time, without suspending all Broadcast TWT schedules at the same time, and without suspending all R-TWT schedules at the same time.

[0182] Step 202: The site device 101 sends the first radio frame.

[0183] In this way, when the access point device 102 (scheduling AP) and the site device 101 (member STA) want to suspend or resume one (or more) TWT schedules established between the two: if there are other TWT schedules negotiated between the two, the site device 101 can indicate that other TWT schedules will not be suspended when sending the first wireless frame to the access point device 102; on the basis of taking into account the original TWT mechanism, it is possible to avoid the access point device 102 and the site device 101 having to suspend other TWT schedules due to the suspension or resumption operation of one (or more) TWT schedules, resulting in the interruption of low-latency service transmission of other TWT schedules; therefore, the embodiment of the present disclosure is conducive to ensuring the timeliness of low-latency service transmission and improving transmission efficiency.

[0184] Referring to FIG2 , in some embodiments, the first identification information includes a first field;

[0185] The first field includes a first flag bit and one or more first subfields;

[0186] The first flag bit identifies the operation type of the processing operation scheduled for the TWT;

[0187] The first subfield includes identification information of the TWT scheduling.

[0188] Among them, the first identification bit is used to identify the operation type of the processing operation, the operation type is, for example, pause or non-pause; for example, when the first identification bit is set to 1, it identifies that the operation type of the processing operation includes a pause operation; when the first identification bit is set to 1, it identifies that the operation type of the processing operation includes a non-pause operation.

[0189] The first subfield identifies the TWT scheduling corresponding to the processing operation; the first subfield includes identification information of the TWT scheduling, for example, when the first identification bit is set to 1, the R-TWT scheduling identified by the first subfield is suspended; when the first identification bit is set to 0, the R-TWT scheduling identified by the first subfield is not suspended, or the first field may not include the first subfield.

[0190] Referring to FIG2 , in some embodiments, the first subfield includes a first identification field and a second identification field;

[0191] The first identification field includes identification information of the TWT scheduling;

[0192] The second identification field identifies that the uplink transmission operation and / or downlink transmission operation scheduled by the TWT participates in the processing operation.

[0193] Among them, the first identification field is used to identify the identification information of the specific TWT scheduling; for example, it is identified by the Broadcast ID corresponding to the TWT scheduling.

[0194] The second identification field is used to identify: the uplink and downlink transmission operations participating in the operation identified by the first identification bit; optionally, the second identification field can occupy 2 bits, for example, when the second identification field is set to 00, it indicates that the uplink transmission operation scheduled by the TWT identified by the first identification field participates in the operation identified by the first identification bit; when the second identification field is set to 01, it indicates that the downlink transmission operation scheduled by the TWT identified by the first identification field participates in the operation identified by the first identification bit; when the second identification field is set to 10, it indicates that the uplink and downlink transmission operations scheduled by the TWT identified by the first identification field both participate in the operation identified by the first identification bit; when the second identification field is set to 11, it is a reserved bit.

[0195] Step 203: The station device 102 receives the first radio frame.

[0196] Optionally, the first wireless frame includes a first TWT Information frame; for example, the response request subfield (Response Requested subfield) of the first TWT Information frame is set to 1, and all TWT subfields (All TWT subfield) are set to 1, and it contains first identification information, then the first identification information is used to identify the R-TWT scheduling information intended to be suspended and not suspended (protected).

[0197] 3 , after step 203 , the method further includes steps 204 to 207 .

[0198] Step 204: The access point device 102 sends a second wireless frame to the station device 101;

[0199] The Response Requested subfield of the first radio frame is set to a first parameter value, and the second radio frame includes a second TWT Information frame;

[0200] The Response Requested subfield of the first radio frame is set to a second parameter value, and the second radio frame includes an acknowledgment ACK frame.

[0201] If the Response Requested subfield in the first TWT Information frame is set to the first parameter value, for example, the first parameter value is 0, the access point device 102 replies to the site device 101 (member STA) with a second TWT Information frame;

[0202] If the Response Requested subfield in the first TWT Information frame is set to the second parameter value, for example, the second parameter value is 1, the access point device 102 replies with an ACK frame to the site device 101 (member STA), indicating that the first TWT Information frame has been received.

[0203] Step 205 : The site device 101 receives a second wireless frame sent by the access point device 101 .

[0204] Among them, the Response Requested subfield of the second TWT Information frame can be set to 0, indicating that the site device 101 does not need to reply to the TWT Information frame again.

[0205] In some embodiments, the parameters of the TWT Information subfield of the second TWT Information frame are the same as the parameters of the TWT Information subfield of the first TWT Information frame.

[0206] The processing operation on the TWT scheduling identified by the second TWT Information frame is the same as the processing operation on the TWT scheduling identified by the first TWT Information frame.

[0207] For example, the parameters of the processing operation on the TWT scheduling identified in the TWT Information subfield of the second TWT Information frame may be the same as the processing operation on the TWT scheduling identified in the first TWT Information frame.

[0208] After step 205 , the station device 101 and the access point device 101 execute steps 206 and 207 respectively.

[0209] Step 206: The second wireless frame includes the ACK frame, and the processing operation is performed on all the TWT scheduling.

[0210] Among them, if the site device 101 receives the ACK response from the access point device 101, the site device 101 enters the power saving mode and suspends all Broadcast TWT scheduling and R-TWT scheduling, and the access point device 102 suspends all Broadcast TWT scheduling and R-TWT scheduling of the site device 101.

[0211] Step 207: The second wireless frame includes a second TWT Information frame, and performs the processing operation identified by the first TWT Information frame.
