[0031] 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.

[0032] The embodiments of the present disclosure provide a low-latency service transmission method, electronic device, and storage medium to further improve the rTWT mechanism and ensure the transmission of low-latency services.

[0033] 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.

[0034] like Figure 1 As shown, Figure 1 This diagram illustrates an application scenario for the low-latency service transmission method in an embodiment of the present disclosure. An AP, such as a device with wireless-to-wired bridging functionality, is responsible for extending services provided by a wired network to a wireless network. A TDLS device, such as a station (STA), is an electronic device with wireless network access functionality that provides a frame delivery service to enable information transmission.

[0035] Step 101: A first AP sends a first radio frame to a STA, where the first radio frame is, for example, a beacon frame or a probe response frame.

[0036] Among them, the first AP is the AP currently associated (Association) with the STA; the first restricted target wake time (Restricted Target Wake Time, rTWT) service time (ServicePeriod, SP) of the first AP and the second rTWT SP of the second AP are identified in the first wireless frame; the second AP is a neighbor AP of the first AP. In the embodiment of the present disclosure, the neighbor AP is, for example, an AP that is relatively close to the first AP in logical topology, for example, the first AP receives a higher signal strength from the neighbor AP, or an AP that is physically close to the first AP, or an AP that is in the same basic service set (BSS) as the first AP; in a WLAN, the AP can obtain the basic service set identifier (BSSID) sent by other APs through channel detection and then discover the neighbor AP. Among them, the neighbor AP can be recommended to the STA as a better roaming target; in addition, considering the neighbor AP when adjusting the radio frequency parameters can make full use of spectrum resources and can achieve load balancing among multiple APs.

[0037] Optionally, the first wireless frame includes identification information of the second AP, which is used to identify the neighbor AP corresponding to the second rTWTSP; for example, if the first AP carries rTWT SPs of multiple neighbor APs in the first wireless frame, the rTWT SP of each neighbor AP is identified by the identification information of the neighbor AP.

[0038] Furthermore, the identification information includes: a media access control layer (MAC) address, an AP MLD address of a multi-link access point device (AP MLD) to which the second AP belongs, and at least one of a basic service set (BSS) color.

[0039] The MAC address is the MAC address of the neighboring AP in its working link. The BSS color is the BSS color value of the BSS formed by the AP attached to the AP MLD in a certain link.

[0040] Optionally, the identification information of the first rTWT SP, the second rTWT SP and the second AP may be carried in a TWTelement, and the first AP carries a TWT element in the first radio frame; for example, the identification information of the second AP is carried in the traffic info control field of the broadcast TWT parameter set field of the TWTelement.

[0041] As an example, the format of the Broadcast TWT Parameter Set field may be as shown in Table 1 below:

[0042] Table 1:

[0043]

[0044] Among them, when the Restricted TWT Traffic Info present subfield is set to 1, the Restricted TWT Traffic Info subfield exists in the Restricted TWT Parameter Set field, and the format of the Restricted TWT Traffic Info subfield is shown in Table 2 below:

[0045] Table 2:

[0046]

[0047] The identification information of the second AP may be carried in the Traffic Info Control field. The format of the Traffic Info Control field is shown in Table 3 below. The identification information of the second AP may be carried in the reserved subfield.

[0048] Table 3:

[0049]

[0050] Step 102: The first rTWT SP and the second rTWT SP at least partially overlap in time.

[0051] like Figure 2 In the application scenario shown, a first AP (AP1) shares the rTWT SP of a second AP (AP2), and the first rTWT SP and the second rTWT SP at least partially overlap in time. It will be understood that in the embodiments of the present disclosure, at least partial overlap, for example: the first rTWT SP and the second rTWT SP partially overlap or completely overlap in time; if AP1 and STA1 perform downlink communication in the first rTWT SP while STA2 and AP2 perform uplink communication in the second rTWT SP, then STA2's transmission will interfere with STA1's data reception, so that the network resource allocation in the second rTWT SP will be wasted and may not meet the transmission requirements of low-latency services.

[0052] For ease of explanation, in the embodiments of the present disclosure, STA1 refers to a STA associated with a first AP, and STA2 refers to a STA associated with a second AP.

[0053] Therefore, the STA determines whether to join the first rTWT SP according to whether it can receive the message frame of the second AP.

[0054] Step 103: The STA can receive the message frame from the second AP and does not join the first rTWT SP.

[0055] Among them, the message frame of the second AP is used as the inter-PPDU. If the STA can receive the inter-PPDU of the second AP, STA2 can also receive the inter-PPDU of the first AP when communicating with the second AP, indicating that the communication between STA1 and the first AP will interfere with the communication between the second AP and its associated STA2; therefore, when the first rTWT SP and the second rTWT SP are at least partially overlapped in time and the STA can receive the message frame of the second AP, the STA does not join the first rTWT SP and does not send a TWT Setup frame to the first AP, thereby avoiding interference with the low-latency service transmitted between the second AP and its associated STA2.

[0056] Among them, the STA receives a message frame carrying the same identification information, determining that the STA can receive the message frame of the second AP; for example, taking the identification information of the second AP including BSS color as an example, the BSS color value carried by the inter-PPDU received by the STA is consistent with the BSS color value of the second AP, then it is determined that the STA can receive the message frame of the second AP.

[0057] Specifically, TWT is a technology for energy saving that aims to further reduce the power consumption of Wi-Fi networks. Specifically, TWT technology enables STA and AP to negotiate the service period (SP) to determine the STA sleep and wake-up time and frequency; STA remains active and communicates during the service period, so that it can sleep outside the service period to achieve the purpose of energy saving. In addition, TWT technology can also enable the AP to provide higher quality services to multiple STAs, minimize competition or overlap, and improve spectrum efficiency while reducing the power consumption of the Wi-Fi network.

[0058] In low-latency transmission scenarios, the real-time data traffic of many 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, a restricted-Target Wake Time (rTWT) is proposed based on the technology of TWT. The rTWT mechanism allows the AP to use enhanced media access protection mechanism and resource reservation mechanism to provide more predictable delay to distinguish delay-sensitive traffic from other types of traffic, so that the AP can reduce the worst-case delay and / or reduce jitter to provide more reliable services. Within the second rTWT SP, the second AP reserves transmission resources for low-latency services. Therefore, when the first rTWT SP and the second rTWT SP overlap at least partially in time and the STA can receive the message frame of the second AP, the STA does not join the first rTWT SP and does not send a TWT Setup frame to the first AP, so as to avoid interfering with the low-latency services transmitted between the second AP and its associated STA2.

[0059] Step 104: The STA cannot receive the message frame from the second AP and joins the first rTWT SP.

[0060] On the contrary, if the STA cannot receive the message frame of the second AP, the STA joins the first rTWT SP, executes step 105, and sends a TWT Setup frame to the first AP to transmit low-latency services and improve spectrum utilization.

[0061] In an embodiment of the present disclosure, a STA receives a first wireless frame sent by a first AP, wherein the first wireless frame identifies a first rTWT SP of the first AP and a second rTWT SP of a second AP; the first rTWT SP and the second rTWT SP at least partially overlap in time, and the STA can receive a message frame of the second AP and does not join the first rTWT SP, thereby avoiding interference with low-latency services transmitted between the second AP and its associated STAs; if the STA cannot receive a message frame of the second AP, it joins the first rTWT SP to improve frequency utilization. An embodiment of the present disclosure provides a low-latency service transmission method to further improve the rTWT mechanism and ensure the transmission of low-latency services.

[0062] See also Figure 3 The present disclosure provides a low-latency service transmission method, which is applied to a station device STA. The method includes:

[0063] Step 301: Receive a first wireless frame sent by a first AP; wherein the first wireless frame identifies a first rTWT SP of the first AP and a second rTWT SP of a second AP.

[0064] Among them, the first AP is the AP currently associated (Association) with the STA. The STA receives the first wireless frame sent by the first AP, and the first wireless frame identifies the rTWT SP of the first AP and the second rTWT SP of the second AP; the second AP is the neighbor AP of the first AP. In the embodiment of the present disclosure, the neighbor AP is, for example, an AP that is relatively close to the first AP in logical topology, for example, the first AP receives a higher signal strength from the neighbor AP, or an AP that is physically close to the first AP, or an AP that is in the same BSS as the first AP; in WLAN, the AP can obtain the BSSID sent by other APs through channel detection and then discover the neighbor AP. Among them, the neighbor AP can be recommended to the STA as a better roaming target; in addition, considering the neighbor AP when adjusting the radio frequency parameters can make full use of spectrum resources and can achieve load balancing among multiple APs.

[0065] Step 302: The first rTWT SP and the second rTWT SP at least partially overlap in time. The STA determines whether to join the first rTWT SP according to whether it can receive the message frame of the second AP.

[0066] like Figure 2 In the application scenario shown, the first AP shares the rTWT SP of the second AP, and the first rTWT SP and the second rTWT SP at least partially overlap in time. The STA determines whether to join the first rTWT SP based on whether it can receive the message frame of the second AP.

[0067] For example, if AP1 and STA1 are communicating downlink in the first rTWT SP while STA2 and AP2 are communicating uplink in the second rTWT SP, STA2's transmission will interfere with STA1's data reception. In this way, the network resource allocation in the second rTWT SP will be wasted and may not be able to meet the transmission requirements of low-latency services. Conversely, if the STA cannot receive the message frame of the second AP, the STA joins the first rTWT SP to improve frequency utilization.

[0068] Optionally, in the embodiment of the present disclosure, determining whether to join the first rTWT SP according to whether the STA can receive the message frame of the second AP includes:

[0069] The STA can receive the message frame of the second AP and does not join the first rTWT SP;

[0070] or

[0071] The STA cannot receive the message frame of the second AP and joins the first rTWT SP.

[0072] Among them, if the STA can receive the message frame of the second AP, it will not join the first rTWT SP to avoid interference with the low-latency service transmitted between the second AP and its associated STA; if the STA cannot receive the message frame of the second AP, it will join the first rTWT SP to improve frequency utilization.

[0073] Optionally, in an embodiment of the present disclosure, the first wireless frame includes identification information of the second AP, which is used to identify the neighbor AP corresponding to the second rTWT SP; for example, the first AP carries the rTWT SPs of multiple neighbor APs in the first wireless frame, and the rTWT SP of each neighbor AP is identified by the identification information of the neighbor AP.

[0074] The identification information includes: at least one of a MAC address, an AP MLD address of an AP MLD to which the second AP belongs, and a BSS color;

[0075] Optionally, in the embodiment of the present disclosure, the method further includes:

[0076] The STA receives a message frame carrying the same identification information, and determines that the STA can receive the message frame of the second AP. For example, taking the identification information of the second AP including a BSS color as an example, if the BSS color value carried in the inter-PPDU received by the STA is consistent with the BSS color value of the second AP, then it is determined that the STA can receive the message frame of the second AP.

[0077] Optionally, in an embodiment of the present disclosure, the identification information of the second AP is carried in the traffic information control field of the broadcast TWT parameter set field of the TWT element of the first wireless frame; referring to Tables 1 to 3 above, the identification information of the second AP can be carried in the TWT element, and the first AP carries the TWT element in the first wireless frame; the identification information of the second AP is carried in the traffic information control field (traffic info control field) of the broadcast TWT parameter set field of the TWT element.

[0078] Optionally, in the embodiment of the present disclosure, the adding of the first rTWT SP includes:

[0079] Sending a first TWT setup frame (TWT Setup frame) to the first AP;

[0080] Among them, the first TWT establishes a frame request to become a member of the rWT schedule (Schedule) corresponding to the first rTWT SP to transmit low-latency services and improve spectrum utilization.

[0081] In an embodiment of the present disclosure, a STA receives a first wireless frame sent by a first AP, wherein the first wireless frame identifies a first rTWT SP of the first AP and a second rTWT SP of a second AP; the first rTWT SP and the second rTWT SP at least partially overlap in time, and the STA can receive a message frame of the second AP and does not join the first rTWT SP, thereby avoiding interference with low-latency services transmitted between the second AP and its associated STAs; if the STA cannot receive a message frame of the second AP, it joins the first rTWT SP to improve frequency utilization.

[0082] See also Figure 4 The embodiment of the present disclosure provides a low-latency service transmission method, which is applied to a first access point device AP. The method includes:

[0083] Step 401: Determine a first radio frame; wherein the first radio frame identifies a first rTWT SP of a first AP and a second rTWT SP of a second AP.

[0084] Among them, the first AP is the AP currently associated (Association) with the STA. The first AP determines a first wireless frame, in which the rTWT SP of the first AP and the second rTWT SP of the second AP are identified; the second AP is a neighbor AP of the first AP. In the embodiment of the present disclosure, the neighbor AP is, for example, an AP that is relatively close to the first AP in logical topology, for example, the first AP receives a higher signal strength from the neighbor AP, or an AP that is physically close to the first AP, or an AP that is in the same BSS as the first AP; in WLAN, the AP can obtain the BSSID sent by other APs through channel detection and thus discover the neighbor AP. Among them, the neighbor AP can be recommended to the STA as a better roaming target; in addition, considering the neighbor AP when adjusting the radio frequency parameters can make full use of spectrum resources and can achieve load balancing among multiple APs.

[0085] Step 402: Send a first radio frame to instruct the station device STA to determine whether to join the first rTWT SP based on whether it can receive the message frame of the second AP; wherein the first rTWT SP and the second rTWT SP at least partially overlap in time.

[0086] The first AP shares the rTWT SP of the second AP, and the first rTWT SP and the second rTWT SP at least partially overlap in time. The first AP instructs the STA to determine whether to join the first rTWT SP based on whether it can receive the message frame of the second AP.

[0087] For example, if AP1 and STA1 are communicating downlink in the first rTWT SP while STA2 and AP2 are communicating uplink in the second rTWT SP, STA2's transmission will interfere with STA1's data reception. In this way, the network resource allocation in the second rTWT SP will be wasted and may not be able to meet the transmission requirements of low-latency services. Conversely, if the STA cannot receive the message frame of the second AP, the STA joins the first rTWT SP to improve frequency utilization.

[0088] Optionally, in the embodiment of the present disclosure, the indicating station device STA determines whether to join the first rTWT SP according to whether the message frame of the second AP can be received, including:

[0089] Instructing the STA to join the first rTWT SP if it can receive the message frame of the second AP;

[0090] or

[0091] Indicates that the STA cannot receive the message frame of the second AP and joins the first rTWT SP.

[0092] Among them, if the STA can receive the message frame of the second AP, the first AP instructs the STA not to join the first rTWTSP to avoid interference with the low-latency service transmitted between the second AP and its associated STA; if the STA cannot receive the message frame of the second AP, the first AP instructs the STA to join the first rTWT SP to improve frequency utilization.

[0093] Optionally, in the embodiment of the present disclosure, the first wireless frame includes identification information of the second AP;

[0094] The identification information includes at least one of a MAC address, an AP MLD address of an AP MLD to which the second AP belongs, and a BSS color.

[0095] The identification information is used to identify the neighbor AP corresponding to the second rTWT SP; for example, if the first AP carries the rTWT SPs of multiple neighbor APs in the first wireless frame, the rTWT SP of each neighbor AP is identified by the identification information of the neighbor AP.

[0096] Optionally, in an embodiment of the present disclosure, the identification information of the second AP is carried in the transmission information control field (traffic info control field) of the broadcast TWT parameter set field of the TWT element of the first wireless frame. Referring to Tables 1 to 3 above, the identification information of the second AP can be carried in the TWT element, and the first AP carries the TWTelement in the first wireless frame; the identification information of the second AP is carried in the transmission information control field (traffic info control field) of the broadcast TWT parameter set field of the TWT element.

[0097] Optionally, in the embodiment of the present disclosure, after sending the first radio frame, the method includes:

[0098] Receive a first TWT setup frame (TWT Setup frame) sent by the STA;

[0099] Among them, the first TWT establishes a frame request to become a member of the rTWT scheduling corresponding to the first rTWT SP to transmit low-latency services and improve spectrum utilization.

[0100] In an embodiment of the present disclosure, a first AP determines and sends a first wireless frame, and the first rTWT SP of the first AP and the second rTWT SP of the second AP are identified in the first wireless frame; the first rTWT SP and the second rTWT SP are at least partially overlapped in time, and the STA can receive the message frame of the second AP and does not join the first rTWT SP to avoid interference with the low-latency service transmitted between the second AP and its associated STA; if the STA cannot receive the message frame of the second AP, it joins the first rTWT SP to improve frequency utilization.
