[0039] In a first aspect, an embodiment of the present disclosure provides a data frame transmission method, the method comprising:

[0040] The station device STA determines a first radio frame; wherein the first radio frame includes first identification information, and the first identification information identifies that: the STA sends an uplink buffered data frame during an awake period of an access point device AP; the uplink buffered data frame is buffered by the STA during a time when the AP is in a power saving state;

[0041] The first radio frame is sent.

[0042] In the above embodiment, the first identification information is used to identify: the STA sends an uplink cache data frame during the awake period of the access point device AP; and the uplink data cached during the time when the AP is in the power saving state is transmitted, thereby improving the data transmission rate and reducing the transmission delay.

[0043] In combination with some embodiments of the first aspect, in some embodiments, the first radio frame includes a newly defined frame and / or a first ACK frame.

[0044] In the above embodiment, the newly defined frame is named as BSR control frame, for example; the first ACK frame is sent in response to the radio frame sent by the access point device, and while responding to the radio frame, it notifies the access point device to prepare to receive the uplink buffer data frame.

[0045] In combination with some embodiments of the first aspect, in some embodiments, the newly defined frame includes a BSR control frame.

[0046] In the above embodiment, the first identification information is carried in the BSR control frame to notify the access point device to prepare to receive the uplink buffer data frame.

[0047] In conjunction with some embodiments of the first aspect, in some embodiments, the first identification information includes: first link bitmap information;

[0048] The first link bitmap information is set to a first parameter value, indicating that the STA has the uplink cache data frame under the link corresponding to the first link bitmap information.

[0049] In the above embodiment, the first link bitmap information is set to the first parameter value. For example, if the first parameter value is 1, it indicates that the STA has cached uplink data frames that need to be transmitted under the corresponding link; if the first link bitmap information is set to 0, it indicates that the STA has no cached uplink data frames that need to be transmitted under the corresponding link.

[0050] In combination with some embodiments of the first aspect, in some embodiments, the first ACK frame is sent by the STA in response to a downlink buffer data frame sent by the AP.

[0051] In the above embodiment, the site device receives the downlink buffered data frame sent by the AP (the AP may be an access point device, an attached AP of the access point device, or an AP attached to the same AP MLD as the access point device, which is not limited in the embodiment of the present disclosure) under the link where the AP is awake.

[0119] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0120] As shown in FIG1 , a communication system 100 includes a station device (STA) 101 and an access point device (AP) 102 .

[0121] 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.

[0122] 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.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] The various embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network that adopts the 802.11 series of protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices with certain associations 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 with a dedicated BSS management function, which is called an access point device, and other stations in the BSS network that are not APs are called terminals, also called non-AP STAs. APs 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, etc., a STA cannot detect other STAs that are farther away from it, and the two are hidden nodes of each other.

[0128] FIG2 is one of the interactive schematic diagrams of the data frame transmission method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0129] 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 identifies that: the STA sends an uplink cache data frame during the awake period of the access point device AP; the uplink cache data frame is cached by the STA during the time when the AP is in a power saving state.

[0130] In UHR, power saving (PS) is a research priority, but AP power saving is still under development. Typically, APs come in three forms: soft APs (or soft AP MLD), non-simultaneous transmitting and receiving (NSTR) mobile APs (or NSTR mobileAP MLD), and regular APs (or regular AP MLD). Regular APs, such as routers, support both simultaneous transmitting and receiving (STR) and NSTR communications. For example, soft APs and NSTR mobile APs are typically battery-powered, resulting in high power consumption. Furthermore, their communication with STAs is typically not continuous for extended periods. Therefore, a mechanism to support AP power saving is required.

[0131] In UHR, APs may still support multi-link communication, and STAs may also be attached to non-AP MLDs that also support multi-link communication. Multi-link communication between the two will also be established according to the existing 802.11be architecture. Because the AP or AP MLD may enter power-saving mode on each link, and the AP will wake up at regular intervals for uplink and downlink transmission on each link, reducing latency is also a research focus in UHR. If the AP enters a dormant state for a longer period, the service transmission delay will also increase, which may not meet low-latency requirements. Mechanisms are needed to ensure that STAs can transmit uplink low-latency services in a timely manner even when the AP is dormant.

[0132] In the disclosed embodiment, the station device 101 determines a first radio frame and carries first identification information in the first radio frame. The first identification information indicates that the STA sends an uplink buffered data frame during the AP's wake-up period (Wake Time); the uplink buffered data frame is buffered by the STA while the AP is in a power-saving state (Power Save). The first identification information notifies the AP that the station device 101 will send the uplink buffered data frame during the AP's wake-up period, so that the AP receives the uplink buffered data frame during its wake-up period, thereby ensuring the transmission of the uplink buffered data frame.

[0133] Step 202: The site device 101 sends the first radio frame.

[0134] The site device 101 sends a first radio frame to the access point device 102 to notify the access point device 102 to prepare to receive the uplink buffer data frame to transmit uplink data, thereby increasing the data transmission rate and reducing the transmission delay.

[0135] In some embodiments, the first radio frame includes a newly defined frame and / or a first ACK frame.

[0136] The newly defined frame is named, for example, a BSR control frame; the first ACK frame is sent, for example, in response to a wireless frame sent by the access point device 102, and simultaneously notifies the access point device 102 to prepare to receive the uplink buffered data frame.

[0137] The first radio frame may include one of a newly defined frame and a first ACK frame, that is, the first identification information is carried by the newly defined frame or the first ACK frame.

[0138] The first wireless frame can also be jointly indicated by the newly defined frame and the first ACK frame. For example, an identification bit is set in the newly defined frame to indicate the first identification information. The identification bit is set to 1, indicating that the STA sends an uplink cache data frame during the wake-up period of the access point device AP; and the first ACK frame includes a control field, and the link bitmap information is set in the control field; the second link bitmap information is set to a second parameter value, indicating that the STA has the uplink cache data frame under the link corresponding to the second link bitmap information.

[0139] In some embodiments, the first identification information includes: first link bitmap information;

[0140] The first link bitmap information is set to a first parameter value, indicating that the STA has the uplink cache data frame under the link corresponding to the first link bitmap information.

[0141] Among them, for example, the first link bitmap information is added to the BSR control frame, and the first link bitmap information is set to the first parameter value. For example, the first parameter value is 1, which indicates that the STA has cached uplink data frames that need to be transmitted under the corresponding link; the first link bitmap information is set to 0, which indicates that the STA has no cached uplink data frames that need to be transmitted under the corresponding link.

[0142] In some embodiments, the first ACK frame is sent by the STA in response to a downlink buffer data frame sent by the AP.

[0143] Among them, the site device 101 receives the downlink buffered data frame sent by the AP (the AP may be the access point device 102, or an affiliated AP of the access point device 102, or an AP affiliated with the same AP MLD as the access point device 102, which is not limited in the embodiment of the present disclosure) under the link where the AP is awake, and then notifies the access point device 102 to prepare to receive the uplink buffered data frame while responding to the wireless frame.

[0144] In some embodiments, the first ACK frame includes a control field (or control field);

[0145] The control field includes: second link bitmap information;

[0146] The second link bitmap information is set to a second parameter value, indicating that the STA has the uplink cache data frame under the link corresponding to the second link bitmap information.

[0147] Among them, for example, the second link bitmap information is added to the first ACK frame, and the second link bitmap information is set to the second parameter value. For example, the second parameter value is 1, which indicates that the STA has cached uplink data frames that need to be transmitted under the corresponding link; the second link bitmap information is set to 0, which indicates that the STA has no cached uplink data frames that need to be transmitted under the corresponding link.

[0148] In some embodiments, the first identification information includes: a data frame size of the uplink buffered data frame buffered by the STA.

[0149] The size of the data frames cached by the site device 101, such as the queue size of the cached data, identifies the amount of cached data. The first identification information includes the amount of data cached by the site device 101, so that the access point device 102 understands that the site device 101 needs to wake up other access point devices to receive the cached uplink data frames, thereby ensuring the transmission latency of low-latency services.

[0150] Step 203: The access point device 102 receives the first wireless frame.

[0151] The access point device 102 receives the first radio frame, and determines whether the site device 101 sends an uplink buffered data frame within the AP awake period according to identification information in the first radio frame.

[0152] Step 204 : The station device 101 sends a PS-poll frame to the access point device 102 .

[0153] In the case where the access point device 102 that needs to receive the uplink buffered data frame is a subordinate AP of a certain AP MLD, the subordinate AP needs to wake up on the corresponding link to receive the uplink buffered data frame sent by the site device 101. Specifically, the site device 101 can wake up the subordinate AP by sending a PS-poll frame.

[0154] Step 205: The access point device 102 sends a second ACK frame.

[0155] The second ACK frame is used to respond to the PS-poll frame.

[0156] Step 206: The site device 101 sends the uplink buffered data frame.

[0157] The station device 101 sends the buffered uplink buffered data frame to the access point device 102, so that the access point device 102 receives the uplink buffered data frame during its awake period, thereby ensuring the transmission of the uplink buffered data frame.

[0158] The data frame transmission method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, step 201 can be implemented as an independent embodiment, step 202 can be implemented as an independent embodiment, step 204 can be implemented as an independent embodiment, step 205 can be implemented as an independent embodiment, and step 206 can be implemented as an independent embodiment; the combination of step 201 and step 202 can be implemented as an independent embodiment, and the combination of step 204 and step 205 can be implemented as an independent embodiment, but the present invention is not limited thereto.

[0159] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 .

[0160] FIG3 is a second interactive diagram of a data frame transmission method according to an embodiment of the present disclosure. As shown in FIG3 , the method includes:

[0161] In step 301, the site device 101 determines a first wireless frame; wherein the first wireless frame includes first identification information, and the first identification information identifies that: the STA sends an uplink cache data frame during the awake period of the access point device AP; the uplink cache data frame is cached by the STA during the time when the AP is in a power saving state.

[0162] In UHR, power saving (PS) is a research priority, but AP power saving is still under development. Typically, APs come in three forms: soft APs (or soft AP MLD), non-simultaneous transmitting and receiving (NSTR) mobile APs (or NSTR mobileAP MLD), and regular APs (or regular AP MLD). Regular APs, such as routers, support both simultaneous transmitting and receiving (STR) and NSTR communications. For example, soft APs and NSTR mobile APs are typically battery-powered, resulting in high power consumption. Furthermore, their communication with STAs is typically not continuous for extended periods. Therefore, a mechanism to support AP power saving is required.

[0163] In UHR, APs may still support multi-link communication, and STAs may also be attached to non-AP MLDs that also support multi-link communication. Multi-link communication between the two will also be established according to the existing 802.11be architecture. Because the AP or AP MLD may enter power-saving mode on each link, and the AP will wake up at regular intervals for uplink and downlink transmission on each link, reducing latency is also a research focus in UHR. If the AP enters a dormant state for a longer period, the service transmission delay will also increase, which may not meet low-latency requirements. Mechanisms are needed to ensure that STAs can transmit uplink low-latency services in a timely manner even when the AP is dormant.

[0164] In the disclosed embodiment, the station device 101 determines a first radio frame and carries first identification information in the first radio frame. The first identification information indicates that the STA sends an uplink buffered data frame during the AP's wake-up period (Wake Time); the uplink buffered data frame is buffered by the STA while the AP is in a power-saving state (Power Save). The first identification information notifies the AP that the station device 101 will send the uplink buffered data frame during the AP's wake-up period, so that the AP receives the uplink buffered data frame during its wake-up period, thereby ensuring the transmission of the uplink buffered data frame.

[0165] Step 302: The site device 101 sends the first radio frame.

[0166] The site device 101 sends a first radio frame to the access point device 102 to notify the access point device 102 to prepare to receive the uplink buffer data frame to transmit uplink data, thereby increasing the data transmission rate and reducing the transmission delay.

[0167] In some embodiments, the first radio frame includes a newly defined frame and / or a first ACK frame.

[0168] The newly defined frame is named, for example, a BSR control frame; the first ACK frame is sent, for example, in response to a wireless frame sent by the access point device 102, and simultaneously notifies the access point device 102 to prepare to receive the uplink buffered data frame.

[0169] The first radio frame may include one of a newly defined frame and a first ACK frame, that is, the first identification information is carried by the newly defined frame or the first ACK frame.

[0170] The first wireless frame can also be jointly indicated by the newly defined frame and the first ACK frame. For example, an identification bit is set in the newly defined frame to indicate the first identification information. The identification bit is set to 1, indicating that the STA sends an uplink cache data frame during the wake-up period of the access point device AP; and the first ACK frame includes a control field, and the link bitmap information is set in the control field; the second link bitmap information is set to a second parameter value, indicating that the STA has the uplink cache data frame under the link corresponding to the second link bitmap information.

[0171] In some embodiments, the first identification information includes: first link bitmap information;

[0172] The first link bitmap information is set to a first parameter value, indicating that the STA has the uplink cache data frame under the link corresponding to the first link bitmap information.

[0173] Among them, for example, the first link bitmap information is added to the BSR control frame, and the first link bitmap information is set to the first parameter value. For example, the first parameter value is 1, which indicates that the STA has cached uplink data frames that need to be transmitted under the corresponding link; the first link bitmap information is set to 0, which indicates that the STA has no cached uplink data frames that need to be transmitted under the corresponding link.

[0174] In some embodiments, the first ACK frame is sent by the STA in response to a downlink buffer data frame sent by the AP.

[0175] Among them, the site device 101 receives the downlink buffered data frame sent by the AP (the AP may be the access point device 102, or an affiliated AP of the access point device 102, or an AP affiliated with the same AP MLD as the access point device 102, which is not limited in the embodiment of the present disclosure) under the link where the AP is awake, and then notifies the access point device 102 to prepare to receive the uplink buffered data frame while responding to the wireless frame.

[0176] In some embodiments, the first ACK frame includes a control field (or control field);

[0177] The control field includes: second link bitmap information;

[0178] The second link bitmap information is set to a second parameter value, indicating that the STA has the uplink cache data frame under the link corresponding to the second link bitmap information.

[0179] Among them, for example, the second link bitmap information is added to the first ACK frame, and the second link bitmap information is set to the second parameter value. For example, the second parameter value is 1, which indicates that the STA has cached uplink data frames that need to be transmitted under the corresponding link; the second link bitmap information is set to 0, which indicates that the STA has no cached uplink data frames that need to be transmitted under the corresponding link.

[0180] In some embodiments, the first identification information includes: a data frame size of the uplink buffered data frame buffered by the STA.

[0181] The size of the data frames cached by the site device 101, such as the queue size of the cached data, identifies the amount of cached data. The first identification information includes the amount of data cached by the site device 101, so that the access point device 102 understands that the site device 101 needs to wake up other access point devices to receive the cached uplink data frames, thereby ensuring the transmission latency of low-latency services.

[0182] Step 303: The access point device 102 receives the first wireless frame.

[0183] The access point device 102 receives the first radio frame, and determines whether the site device 101 sends an uplink buffered data frame within the AP awake period according to identification information in the first radio frame.

[0184] Step 304 : The access point device 102 sends a poll frame to the station device 101 .

[0185] Among them, under a certain link, the access point device 102 may receive the first wireless frames sent by multiple site devices 101, then the access point device 102 sends a poll frame to the site device 101 under the link marked with the cached uplink data frame to poll the site device 101 under the link, and wait for the site device 101 to respond, for example, by sending a third ACK frame response.

[0186] The poll frame includes: identification information of the STA and resource information of the STA replying to the third ACK frame;

[0187] The identification information of the STA is used to uniquely identify the STA; the resources indicated by the resource information are used when the STA replies to the third ACK frame.

[0188] In some embodiments, the identification information of the STA includes: Association Identifier (AID) information or Media Access Control (MAC) address information of the STA.

[0189] Step 305: The access point device 102 sends the third ACK frame.

[0190] The third ACK frame is used to respond to the poll frame.

[0191] Step 306: The access point device 102 sends a trigger frame; the trigger frame includes: identification information of the STA and resource information or MCS mode for the STA to send the uplink buffer data frame.

[0192] If the access point device 102 has obtained the data frame size of the uplink buffered data frame, it sends a trigger frame to the station device 101. The trigger frame is used to trigger the station device 101 to send the uplink buffered data frame; therefore, the trigger frame includes the uplink data frame sending resource, the STA identifier AID or MAC address, the modulation and coding scheme (MCS), etc.

[0193] Step 307: The site device 101 sends the uplink buffered data frame.

[0194] The station device 101 sends the buffered uplink buffered data frame to the access point device 102, so that the access point device 102 receives the uplink buffered data frame during its awake period, thereby ensuring the transmission of the uplink buffered data frame.

[0195] The data frame transmission method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments.
