The embodiment of the disclosure provides a low-delay service negotiation method, electronic equipment and a storage medium, which are used for further improving an R-TWT mechanism and guaranteeing the transmission of low-delay service.

The method and the device are based on the same application, and because the principles of solving the problems by the method and the device are similar, the implementation of the device and the method can be referred to each other, and the repetition is not repeated.

Referring to fig. 1, fig. 1 is a schematic diagram illustrating a partial structure of TWT elements in a low latency service negotiation method according to various embodiments of the present disclosure.

The Access Point (AP) device broadcasts, to a channel direct connection setup (Tunneled Direct Link Setup, TDLS) device through a first radio frame, a Time parameter that can support transmission of low-latency traffic between TDLS devices through a TDLS link within an R-TWT SP (Service Period) of a limited Target Wake Time (R-TWT) schedule. The TDLS device negotiates with the AP through the TWT setup frame and joins as a member of a certain R-TWT schedule.

Alternatively, the AP is responsible for extending services provided by the wired network to the wireless network, such as a device with wireless-to-wired Bridging (Bridging) functionality. TDLS devices such as Station devices (STAs), for example, electronic devices with wireless network access functions, provide Frame Delivery (Frame Delivery) services to allow information to be delivered.

Specifically, the AP determines and transmits a first radio frame, where the first radio frame includes first identification information, where the first identification information includes: in R-TWT SP scheduled by R-TWT, the time parameters of low-delay service are transmitted through a TDLS link between the TDLS devices; in the R-TWT SP, a time parameter is used for transmitting a start time, a duration, etc. of low-latency service transmission between TDLS devices through a TDLS link.

Optionally, as shown in fig. 1, the first identification information is shown in a TDLS R-TWT parameter information field, and the time parameter includes: at least one item of the offset information of the TDLS R-TWT and the duration information of the TDLS R-TWT is used for identifying relevant time information for transmitting low-delay service transmission between the TDLS devices through the TDLS link, and the low-delay service transmission between the TDLS devices through the TDLS link according to the relevant time information is facilitated.

Specifically, the TDLS R-TWT offset information identifies: allowing a target offset time of a start time of low-delay traffic transmitted between the TDLS devices over the TDLS link within the R-TWT SP relative to the start time of the R-TWT SP; for example, when the R-TWT SP starts at time T1 and the target offset time is T2, the start time for allowing the TDLS devices to transmit low-latency traffic through the TDLS link is t3=t1+t2.

The TDLS R-TWT duration information identifies: allowing a target duration of low latency traffic to be transmitted over the TDLS link between the TDLS devices within the R-TWT SP; the target duration time can be used for the TDLS equipment to determine the ending time of transmitting the low-delay service; for example, when the start time of allowing the low-latency traffic to be transmitted between the TDLS devices through the TDLS link is T3 and the target duration is D1, the end time of allowing the low-latency traffic to be transmitted between the TDLS devices through the TDLS link is t4=t3+d1.

Alternatively, as shown in FIG. 1, the first identification information may include TDLS R-TWT parameter information (TDLS R-TWT parameter Info).

Further, as shown in fig. 1, the broadcast TWT parameter set field further includes: a broadcast TWT information subfield (Broadcast TWT Info field);

and setting the R-TWT scheduling information subfield to a first parameter value, and indicating that the R-TWT scheduling supports the transmission of low-delay service through a TDLS link in the R-TWT SP of the TDLS equipment.

Further, as shown in fig. 2, fig. 2 shows an application scenario schematic diagram of a low-latency service negotiation method in an embodiment of the disclosure; wherein the first radio frame includes a Beacon (Beacon) frame or a Probe Response (Probe) frame.

The AP performs step 1 (1-1, 1-2, … … 1-n, each of which may be performed simultaneously or sequentially), and transmits a first radio frame (Beacon frame or Probe response frame) to STA1 (TDLS device 1) and STA2 (TDLS device 2), where the TWT element is carried in the first radio frame.

Among them, the TWT element includes:

(1) Limiting TWT scheduling information field in TWT parameter field: to identify whether the corresponding R-TWT schedule supports TDLS devices for low latency traffic transmission over the TDLS link within the corresponding SP. For example, the corresponding R-TWT schedule may be identified by limiting the TWT schedule information field value to 4;

(2) The TDLS limit TWT offset value is set to: allowing a start time for transmitting a low-latency traffic service between TDLS devices over a TDLS link within a corresponding R-TWT SP, relative to an offset time at which the corresponding R-TWT SP starts;

(3) The TDLS limit TWT duration is set to a time allowed for transmission of low latency traffic durations over the TDLS link between TDLS devices within the corresponding R-TWT SP.

And 2, negotiating by the TDLS device and the AP through the TWT Setup frame, wherein the TDLS device can be added into a certain R-TWT schedule broadcasted by the AP to become a corresponding R-TWT schedule member.

And 3 (3-1, 3-2), when the R-TWT scheduling wake-up time added by the TDLS device arrives, the AP sends a basic trigger frame to the corresponding R-TWT member (TDLS device) to trigger the R-TWT scheduling member to send low-delay service.

And 4, when the target time arrives, transmitting the low-delay service through the TDLS link within the target duration.

As shown in fig. 3, when the Target Wake Time (Target Wake Time) of the R-TWT arrives, the R-TWT SP starts, and low-delay traffic transmission is performed between the R-TWT member and the AP; the low-latency traffic transmission time for the direct link between TDLS devices starts when a TDLS-limited target wake-up time Offset (TDLS R-TWT Offset) time arrives within the R-TWT SP relative to the target wake-up time, the R-TWT schedule members directly transmitting low-latency traffic over the established TDLS link within the TDLS R-TWT Duration (TDLS R-TWT Duration).

In the embodiment of the disclosure, the R-TWT SP is not only used for low-delay service transmission between the R-TWT scheduling AP and the R-TWT scheduling member STA, but also supports the R-TWT scheduling member STA to perform low-delay service transmission through the TDLS link within the duration of the TDLS R-TWT. Based on the R-TWT mechanism, the transmission of deterministic low-delay service is effectively ensured through a periodic target wake-up mechanism, and the transmission efficiency of the low-delay communication service is improved. In addition, communication among the STAs is realized under the condition of no AP based on the TDLS link, and the Peer-to-Peer (P2P) communication mode is used for carrying out data transmission without an access point, so that delay caused by network congestion is avoided, the energy consumption of terminal equipment is reduced, and the data transmission efficiency is improved.

Step 402, transmitting the first radio frame.

TWT is a technology for power saving aimed at further reducing Wi-Fi network power consumption. Specifically, the TWT technique determines STA sleep and wake times and frequencies by having STA and AP negotiate Service Period (SP); the STA keeps active state and communicates during the service time, so that it can sleep at a time other than the service time to achieve the purpose of energy saving. In addition, the TWT technique may also enable the AP to provide higher quality services to multiple STAs, minimize contention or overlap, and improve spectral efficiency while reducing Wi-Fi network power consumption.

In low latency transmission scenarios, more real-time data traffic for applications has stringent delay requirements, e.g., average or maximum delays on the order of several milliseconds to tens of milliseconds, and applications require very little jitter and greater reliability for real-time data traffic. To further ensure communication of low latency traffic, it is proposed to limit the Target Wake Time (R-TWT) based on the TWT technique. The R-TWT mechanism allows the AP 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, such that the AP reduces worst-case delays and/or reduces jitter, providing more reliable services.
