[0036] The embodiments of the present disclosure provide a wireless frame transmission method, a station device, an access point device, and a communication system.

[0037] In a first aspect, an embodiment of the present disclosure provides a wireless frame transmission method, the method comprising:

[0038] The station device STA determines a first radio frame; wherein the first radio frame includes first identification information; the first identification information identifies: delay bound parameter information of a low-latency service transmitted by the station device;

[0039] The first radio frame is sent.

[0040] In the above embodiment, the first identification information is used to identify the delay bound parameter information of the low-latency service transmitted by the site device, so that the access point device obtains the delay bound parameter information of the low-latency service and receives the low-latency service data according to the delay bound parameter information. In this way, for non-periodic low-latency services, such as bursty low-latency services, the site device 101 notifies the access point device through the first identification information, so that the access point device configures transmission resources for the low-latency service according to the delay bound parameters, thereby realizing transmission of the low-latency service.

[0041] In conjunction with some embodiments of the first aspect, in some embodiments, the first identification information further includes at least one of the following:

[0042] The TID of the low-latency service;

[0043] The delay tolerance parameter of the low-latency service.

[0044] In the above embodiment, the TID is used to identify the low-latency service, for example, to determine the link to which the low-latency service is mapped, so that the access point device can configure transmission resources for the low-latency service according to the link.

[0045] The delay tolerance parameter (or delay tolerance) is used to identify the delay tolerance value of low-latency services, such as the maximum transmission delay that can be allowed for low-latency services.

[0046] In conjunction with some embodiments of the first aspect, in some embodiments, the lifetime of the data frame of the low-latency service is:

[0047] The duration indicated by the delay bound parameter information;

[0048] Or the sum of the duration indicated by the delay bound parameter information and the duration indicated by the delay tolerance parameter.

[0049] In the above embodiment, the lifetime of the data frame of the low-latency service can be the duration indicated by the delay bound parameter information; if the delay tolerance parameter exists in the first identification information, the lifetime must also be added with the duration indicated by the delay tolerance parameter.

[0050] Optionally, the lifetime duration can be applied to multiple links that transmit low-latency services.

[0051] In combination with some embodiments of the first aspect, in some embodiments, the delay bound parameter information uses the time synchronization function TSF parameter of the sending link of the first wireless frame as a time reference to facilitate time synchronization.

[0052] In combination with some embodiments of the first aspect, in some embodiments, the first radio frame includes a quality of service QoS data frame or a resource request message frame.

[0053] In the above embodiment, the first radio frame is a QoS data frame, and the first identification information is carried in a Media Access Control (MAC) header portion of the first radio frame, for example, in a Frame Control field of the MAC header. A resource request message frame, such as a Scheduling Request, is used to request access point device 102 to configure uplink transmission resources for station device 101.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0055] Receive a response frame sent by the access point device AP;

[0056] The response frame includes link bitmap information and / or transmission start time information of the low-latency service.

[0057] In the above embodiment, the link bitmap information indicates whether the low-latency service is transmitted on the link corresponding to the link bitmap information, that is, whether the TID of the low-latency service is mapped on the link corresponding to the link bitmap information.

[0058] The transmission start time information of the low-latency service is used by the site device to determine the time to start transmitting the low-latency service data.

[0059] In combination with some embodiments of the first aspect, in some embodiments, the link bitmap information is set to a first parameter value, indicating that the low-latency service is transmitted under the first link corresponding to the link bitmap information, and the first link is the link mapped by the TID of the low-latency service.

[0060] In the above embodiment, the link bitmap information is set to "1", indicating that the TID of the low-latency service is mapped on the link corresponding to the link bitmap information, that is, the link is the first link; the link bitmap information is set to "0", indicating that the TID of the low-latency service is not mapped on the link corresponding to the link bitmap information, that is, the link is not the first link.

[0061] In combination with some embodiments of the first aspect, in some embodiments, the STA supports eMLSR mode, and the first link is an eMLSR link.

[0062] In the above embodiment, if the site device only supports eMLSR, the first link is an eMLSR link, so that the site device 101 sends low-latency services under the eMLSR link, reducing interference from other frames except the above initial control frame.

[0063] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0064] receiving a trigger frame sent by the AP under the first link;

[0065] The data of the low-latency service is sent according to the uplink transmission resources indicated in the trigger frame.

[0066] In the above embodiment, the site device receives the trigger frame sent by the AP under the first link, and sends the data of the low-latency service in the uplink transmission resource according to the uplink transmission resource indicated in the trigger frame.

[0067] In conjunction with some embodiments of the first aspect, in some embodiments, the transmission start time information uses a time synchronization function TSF parameter of a sending link of the first radio frame as a time reference;

[0068] The transmission start time information includes: a TSF offset parameter of each link and a TSF parameter of the sending link.

[0069] In the above embodiment, the TSF parameter of the transmission link of the first radio frame is used as the reference point of time. Since the TSF parameter under each link may be different, the transmission start time information may carry a TSF offset parameter for synchronizing the time of each link.

[0070] In addition, if the site device 101 has obtained the TSF offset value of the corresponding link during the initial association process, the transmission start time information may not carry the TSF offset parameter. The site device 101 determines the TSF parameter based on the TSF offset value obtained during the initial association process, and then performs time synchronization.

[0074] The TID of the low-latency service;

[0075] The delay tolerance parameter of the low-latency service.

[0076] In conjunction with some embodiments of the second aspect, in some embodiments, the lifetime of the data frame of the low-latency service is:

[0077] The duration indicated by the delay bound parameter information;

[0078] Or the sum of the duration indicated by the delay bound parameter information and the duration indicated by the delay tolerance parameter.

[0079] In combination with some embodiments of the second aspect, in some embodiments, the delay bound parameter information uses the time synchronization function TSF parameter of the sending link of the first radio frame as the time reference.

[0080] In combination with some embodiments of the second aspect, in some embodiments, the first radio frame includes a quality of service QoS data frame or a resource request message frame.

[0082] Send response frame;

[0083] The response frame includes link bitmap information and / or transmission start time information of the low-latency service.

[0084] In combination with some embodiments of the second aspect, in some embodiments, the link bitmap information is set to a first parameter value, indicating that the low-latency service is transmitted under the first link corresponding to the link bitmap information, and the first link is the link mapped by the TID of the low-latency service.

[0085] In combination with some embodiments of the second aspect, in some embodiments, the STA supports eMLSR mode, and the first link is an eMLSR link.

[0086] In conjunction with some embodiments of the second aspect, in some embodiments, the method further includes:

[0087] In the first link, a trigger frame is sent; wherein the trigger frame indicates data uplink transmission resources for transmitting the low-latency service.

[0121] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0122] As shown in FIG1 , a communication system 100 includes a station device (STA) 101 and an access point device (AP) 102 .

[0123] In some embodiments, the site device 101 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal includes, but is not limited to, at least one of a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver capabilities, 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 a smart grid, a wireless terminal device used in transportation safety, a wireless terminal device used in a smart city, and a wireless terminal device used in a smart home.

[0124] Specifically, the station device 101 may be a terminal device or network device with a Wireless Fidelity (WiFi) chip. Optionally, the station device 101 may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a, as well as the next generation 802.11 protocol, but is not limited thereto.

[0125] 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, as well as support the next generation 802.11 protocol, but is not limited to these.

[0126] 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] FIG2 is an interactive diagram of a wireless frame transmission method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0131] In step 201, the site device 101 determines a first radio frame; wherein the first radio frame includes first identification information, and the first identification information identifies: delay bound parameter information of a low-latency service transmitted by the site device.

[0132] In UHR, the transmission of low-latency services will be further enhanced. In low-latency transmission scenarios, many applications' real-time data traffic has strict latency requirements. Low-latency services, for example, have average or maximum latencies ranging from a few milliseconds to tens of milliseconds, and applications require real-time data traffic with minimal jitter and strong reliability.

[0133] In an embodiment of the present disclosure, the site device 101 determines a first radio frame and carries first identification information in the first radio frame. The first identification information identifies delay bound parameter information of a low-latency service transmitted by the site device.

[0134] The delay bound parameter information is used to indicate the maximum amount of time allowed to transmit a MAC Service Data Unit (MSDU) or an aggregated MSDU (A-MSDU) of the corresponding service flow. For example, the delay bound parameter information includes an unsigned integer in microseconds. Specifically, for example, if the delay bound parameter information identified by the first identification information indicates a delay bound of 10 milliseconds, then a data frame for the low-latency service must be transmitted within 10 milliseconds after the first radio frame is transmitted.

[0135] Step 202: The site device 101 sends the first radio frame.

[0136] The site device 101 sends the first radio frame, so that the access point device 102 learns the delay bound parameter information of the low-latency service and receives the low-latency service data according to the delay bound parameter information. In this way, for non-periodic low-latency services, such as bursty low-latency services, the site device 101 notifies the access point device 102 through the first identification information, so that the access point device 102 configures transmission resources for the low-latency service according to the delay bound parameters, thereby realizing transmission of the low-latency service.

[0137] In some embodiments, the first identification information further includes at least one of the following:

[0138] Traffic Identifier (TID) of the low-latency service;

[0139] The delay tolerance parameter of the low-latency service.

[0140] The TID is used to identify the low-latency service, for example, to determine the link to which the low-latency service is mapped, so that the access point device 102 can configure transmission resources for the low-latency service according to the link.

[0141] The delay tolerance parameter (or delay tolerance) is used to identify the delay tolerance value of low-latency services, such as the maximum transmission delay that can be allowed for low-latency services.

[0142] In some embodiments, the lifetime of the data frame of the low-latency service is:

[0143] The duration indicated by the delay bound parameter information;

[0144] Or the sum of the duration indicated by the delay bound parameter information and the duration indicated by the delay tolerance parameter.

[0145] Among them, the lifetime duration of the data frame of the low-latency service can be the duration indicated by the delay bound parameter information; if the delay tolerance parameter exists in the first identification information, the lifetime duration must also be added with the duration indicated by the delay tolerance parameter.

[0146] Optionally, the lifetime duration can be applied to multiple links that transmit low-latency services.

[0147] In some embodiments, the delay bound parameter information uses a timing synchronization function (TSF) parameter of a transmission link of the first radio frame as a time reference to facilitate time synchronization.

[0148] In some embodiments, the first radio frame includes a quality of service (QoS) data frame or a resource request message frame. For example, if the first radio frame is a QoS data frame, the first identification information is carried in a media access control (MAC) frame header portion of the first radio frame, such as in a Frame Control field of the MAC frame header. The resource request message frame, such as a Scheduling Request, is used to request the access point device 102 to configure uplink transmission resources for the site device 101.

[0149] Step 203: The access point device 102 receives a first radio frame.

[0150] The access point device 102 receives the first radio frame, obtains delay bound parameter information of the low-latency service, and receives the low-latency service data according to the delay bound parameter information. In this way, for non-periodic low-latency services, such as bursty low-latency services, the site device 101 notifies the access point device 102 through the first identification information, so that the access point device 102 configures transmission resources for the low-latency service according to the delay bound parameters, thereby realizing transmission of the low-latency service.

[0151] Step 204 : The access point device 102 sends a response frame to the station device 101 .

[0152] The access point device 102 coordinates resources for the site device 101 to transmit the uplink low-latency service according to the delay bound parameter requirement of the low latency service in the first identification information, and replies to the site device 101 with the configured transmission resources through a response frame.

[0153] Step 205 , the site device 101 receives the response frame sent by the access point device 102 ;

[0154] The response frame includes link bitmap information and / or transmission start time information of the low-latency service.

[0155] The link bitmap information indicates whether the low-latency service is transmitted on the link corresponding to the link bitmap information, that is, whether the TID of the low-latency service is mapped on the link corresponding to the link bitmap information.

[0156] The transmission start time information of the low-latency service is used by the site device 101 to determine the time to start transmitting the low-latency service data.

[0157] In some embodiments, the transmission start time information uses a time synchronization function TSF parameter of a transmission link of the first radio frame as a time reference;

[0158] The transmission start time information includes: a TSF offset parameter of each link and a TSF parameter of the sending link.

[0159] The TSF parameter of the transmission link of the first radio frame is used as the reference point of time. Since the TSF parameter under each link may be different, the transmission start time information may carry a TSF offset parameter for synchronizing the time of each link.

[0160] In addition, if the site device 101 has obtained the TSF offset value of the corresponding link during the initial association process, the transmission start time information may not carry the TSF offset parameter. The site device 101 determines the TSF parameter based on the TSF offset value obtained during the initial association process, and then performs time synchronization.

[0161] In some embodiments, the link bitmap information is set to a first parameter value, indicating that the low-latency service is transmitted under a first link corresponding to the link bitmap information, where the first link is a link mapped by the TID of the low-latency service.

[0162] For example, the link bitmap information is set to "1", indicating that the TID of the low-latency service is mapped on the link corresponding to the link bitmap information, that is, the link is the first link; the link bitmap information is set to "0", indicating that the TID of the low-latency service is not mapped on the link corresponding to the link bitmap information, that is, the link is not the first link.

[0163] In some embodiments, the STA supports enhanced multi-link single radio (eMLSR) mode, and the first link is an eMLSR link.

[0164] Among them, eMLSR is mainly used for non-AP MLD. In this mode, non-AP MLD can only listen to the channel and receive the initial control frame sent by AP MLD in the form of orthogonal frequency division multiplexing (OFDM) physical layer protocol data unit (PPDU) type and non-high throughput (HT) duplicate (non-HT duplicate) PPDU type. Other types of frames are generally not supported. Therefore, if the site device 101 only supports eMLSR, the first link is an eMLSR link, allowing the site device 101 to send low-latency services under the eMLSR link, reducing interference from other frames other than the above-mentioned initial control frame.

[0165] In step 206 , the access point device 102 sends a trigger frame.

[0166] The access point device 102 sends a trigger frame to the site device 101, and carries the uplink transmission resources configured for the low-latency service in the trigger frame, such as resource units (RU) or multiple resource units (MRU), so that the site device 101 sends data of the low-latency service under the transmission resources.

[0167] Step 207: The site device 101 receives the trigger frame sent by the AP under the first link; and sends the data of the low-latency service according to the uplink transmission resources indicated in the trigger frame.

[0168] The site device 101 receives the trigger frame sent by the AP under the first link, and sends the data of the low-latency service in the uplink transmission resource according to the uplink transmission resource indicated in the trigger frame.

[0169] In the embodiment of the present disclosure, the site device 101 sends the first radio frame, which includes first identification information. The first identification information is used to identify delay bound parameter information of the low-latency service transmitted by the site device, so that the access point device 102 learns the delay bound parameter information of the low-latency service and receives the low-latency service data according to the delay bound parameter information. In this way, for non-periodic low-latency services, such as bursty low-latency services, the site device 101 notifies the access point device 102 through the first identification information, so that the access point device 102 configures transmission resources for the low-latency service according to the delay bound parameters, thereby achieving transmission of the low-latency service.

[0170] In some embodiments, terms such as "moment", "time point", "time", and "time position" can be replaced with each other, and terms such as "duration", "period", "time window", "window", and "time" can be replaced with each other.

[0171] In some embodiments, terms such as wireless access scheme and waveform may be used interchangeably.

[0172] In some embodiments, terms such as "certain", "preset", "preset", "setting", "indicated", "a certain", "any", and "first" can be interchangeable. "Specific A", "preset A", "preset A", "setting A", "indicated A", "a certain A", "any A", and "first A" can be interpreted as A pre-specified in a protocol, etc., or as A obtained through setting, configuration, or indication, etc., or as specific A, a certain A, any A, or first A, etc., but not limited to this.

[0173] In some embodiments, the determination or judgment can be performed by a value represented by 1 bit (0 or 1), or by a true or false value (Boolean value) represented by true or false, or by comparison of numerical values ​​(for example, comparison with a predetermined value), but is not limited thereto.

[0174] In some embodiments, "not expecting to receive" can be interpreted as not receiving on time domain resources and / or frequency domain resources, or as not performing subsequent processing on the data after receiving it; "not expecting to send" can be interpreted as not sending, or as sending but not expecting the recipient to respond to the content sent.
