[0037] The embodiments of the present disclosure provide a communication method, an access point device, a station device, and a communication system.

[0038] In a first aspect, an embodiment of the present disclosure provides a communication method, applied to an access point device, the method comprising:

[0039] Determine a first radio frame; wherein the first radio frame includes first identification information, and the first identification information indicates that after the transmission of the first radio frame is completed, the first low-latency service data is transmitted;

[0040] The first wireless frame is sent to instruct the receiver of the first wireless frame whether to perform delayed feedback on the first non-low-latency service data after the transmission of the first low-latency service data is completed.

[0041] In the above embodiment, the access point device carries first identification information in the first radio frame, and uses the first identification information to identify: after the first radio frame transmission is completed, the first low-latency service data is transmitted; after sending the first radio frame, the access point device instructs the recipient of the first radio frame whether to perform delayed feedback on the first non-low-latency service data after the first low-latency service data transmission is completed; in this way, the site device can determine the transmission timing of the first low-latency service data, and during the transmission of the first low-latency service data, avoid the increase in the transmission delay of the first low-latency service data due to timely feedback on the first non-low-latency service data, thereby reducing the transmission delay of the first low-latency service data.

[0042] In conjunction with some embodiments of the first aspect, in some embodiments, determining the first radio frame includes:

[0043] The access point device sends the first non-low-latency service data, where the first non-low-latency service data is a downlink data frame, and carries the first identification information in a physical layer preamble PHY preamble of the downlink data frame to obtain the first radio frame;

[0044] The access point device receives the first non-low-latency service data, and the first non-low-latency service data is a first uplink data frame. The first identification information is carried in a block acknowledgement frame BA frame of the first uplink data frame to obtain the first wireless frame.

[0045] In the above embodiment, during the process of transmitting the first non-low-latency service data between the access point device and the site device, the access point device can carry the first identification information in the PHY preamble of the downlink data frame, or the site device can carry the first identification information in the PHY preamble of the uplink data frame, thereby obtaining a first wireless frame. There is no restriction on the transmission timing and initiator of the first low-latency service data, and the transmission timing and initiator of the first low-latency service data transmission between the access point device and the site device are enriched.

[0046] In combination with some embodiments of the first aspect, in some embodiments, whether the recipient of the first radio frame performs delayed feedback on the first non-low-latency service data after the first low-latency service data transmission is completed includes:

[0047] The access point device sends the first non-low-latency service data, where the first non-low-latency service data is the downlink data frame, and the receiver performs delayed feedback on the first non-low-latency service data after the first low-latency service data transmission is completed;

[0048] The access point device receives the first non-low-latency service data, and the first non-low-latency service data is the first uplink data frame. After the first low-latency service data transmission is completed, the receiving party does not delay feedback of the first non-low-latency service data.

[0049] In the above embodiment, when the access point device sends first non-low-latency service data to the site device, and the first non-low-latency service data is a downlink data frame, the site device provides delayed feedback for the first non-low-latency service data after the first low-latency service data transmission is completed. This can avoid an increase in the transmission delay of the first low-latency service data due to timely feedback of the first non-low-latency service data during the transmission of the first low-latency service data, thereby reducing the transmission delay of the first low-latency service data. When the access point device receives the first non-low-latency service data, and the first non-low-latency service data is a first uplink data frame, because the first identification information is carried in the BA frame for the first low-latency service data, i.e., feedback for the first non-low-latency service data has already been completed, the access point device does not need to provide feedback for the first non-low-latency service data again after the first low-latency service data transmission is completed.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0051] Receive a second radio frame; wherein the second radio frame includes second identification information, and the second identification information indicates that after the second radio frame is transmitted, the second low-latency service data is transmitted;

[0052] After the second low-latency service data transmission is completed, delayed feedback is performed on the second non-low-latency service data.

[0053] In the above embodiment, the access point device can determine the transmission timing of the second low-latency service data based on the received second wireless frame, so as not to provide timely feedback on the first non-low-latency service data, and after the transmission of the second low-latency service data is completed, the second non-low-latency service data is delayed feedback to reduce the transmission delay of the second low-latency service data.

[0054] In combination with some embodiments of the first aspect, in some embodiments, the access point device receives the second non-low-latency service data, and the second non-low-latency service data is a second uplink data frame, and the second identification information is carried in the second uplink data frame to obtain the second wireless frame.

[0055] In the above embodiment, when the site device sends the second non-low-latency service data to the access point device, the site device can carry the second identification information in the second uplink data frame to indicate that the second low-latency service data is transmitted after the second wireless frame transmission is completed.

[0056] In conjunction with some embodiments of the first aspect, in some embodiments, transmitting the first low-latency service data includes:

[0057] The first low-latency service data includes a first data frame and a second data frame;

[0058] After the transmission of the first data frame is completed and the interval point coordination function interframe space PIFS or short interframe space SIFS is reached, the second data frame is transmitted.

[0059] In the above embodiment, when the first low-latency service data includes multiple frames of data frames, the next frame of data frame is transmitted in the order of the data frames after the previous frame of data frame is transmitted and after an interval of PIFS or SIFS, until each frame of data frame in the first low-latency service data is transmitted. This can avoid the transmission process of the next frame of data frame in the first low-latency service data interfering with the transmission process of the previous frame of data frame.

[0060] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0061] After the first low-latency service data transmission is completed, the first non-low-latency service data continues to be transmitted.

[0062] In the above embodiment, by continuing to transmit the first non-low-latency service data after the first low-latency service data is transmitted, it can be ensured that both the first low-latency service data and the first non-low-latency service data can be transmitted successfully.

[0063] In conjunction with some embodiments of the first aspect, in some embodiments, continuing to transmit the first non-low-latency service data includes:

[0064] The sender of the first non-low-latency service data uses enhanced distributed coordinated access (EDCA) to reacquire the transmission opportunity TXOP, and continues to transmit the first non-low-latency service data within the reacquired TXOP.

[0065] Optionally, the sender of the first non-low-latency service data uses EDCA to regain the transmission opportunity TXOP, and continues to complete the transmission process of the untransmitted first non-low-latency service data within the regained TXOP, thereby ensuring that the first non-low-latency service data can be transmitted successfully.

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

[0121] In some embodiments, the access point device 101 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, 802.11bn, 802.11bf and 802.11a, as well as support the next generation 802.11 protocol, but is not limited to this.

[0122] In some embodiments, the site device 102 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.

[0123] Specifically, the station device 102 may be a terminal device or network device equipped with a Wireless Fidelity (WiFi) chip. Optionally, the station device 102 may support multiple WLAN standards, such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11bn, 802.11bf, and 802.11a, as well as the next generation 802.11 protocol, but is not limited thereto.

[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 an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0129] In step 201, the access point device 101 determines a first wireless frame during the process of transmitting first non-low-latency service data with the site device 102; wherein the first wireless frame includes first identification information, and the first identification information indicates that after the transmission of the first wireless frame is completed, the first low-latency service data is transmitted.

[0130] Optionally, the first identification information may include a pre-emption identifier.

[0131] Optionally, the first identification information may be carried in a MAC (Media Access Control) header of the first radio frame, or in a PHY preamble (Physical preamble) of the first radio frame. When the first identification information is carried in the PHY preamble of the first radio frame, the first identification information may be carried in a signal SIG field of the PHY preamble of the first radio frame.

[0132] Optionally, the access point device 101 may transmit the first non-low-latency service data to the station device 102 within a transmission opportunity TXOP. In the disclosed embodiment, there is no restriction on the initiator (TXOP holder) and responder (TXOP responder) of the TXOP. For example, the access point device 101 may serve as a TXOP holder, obtain a TXOP, and transmit the first non-low-latency service data to the station device 102 within the TXOP; or the station device may serve as a TXOP holder, obtain a TXOP, and transmit the first non-low-latency service data to the access point device 101 within the TXOP.

[0133] In 802.11be, there is a TXOP sharing mechanism, that is, after the AP obtains the TXOP, it will share the TXOP with its associated STA (at most one) for uplink non-TB UL PPDU transmission (non-triggered uplink physical layer protocol data unit transmission, where non-TB means non-triggered based, UL means up-link, and PPDU means Physical Protocol Data Unit) or P2P (Peer to Peer) transmission.

[0134] In some embodiments, step 201 may include step 2011 and step 2022 .

[0135] Step 2011: When the access point device 101 acts as a TXOP holder, obtains a TXOP (transmission opportunity), and sends the first non-low-latency service data (that is, the first non-low-latency service data is a downlink data frame) to the site device 102 within the TXOP, the access point device 101 can obtain the first wireless frame by carrying the first identification information in the PHY preamble of the downlink data frame, indicating that the access point device 101 will send the first non-low-latency service data to the site device 102.

[0136] Step 2012: When the site device 102 acts as a TXOP holder, obtains a TXOP, and sends the first non-low-latency service data (that is, the first non-low-latency service data is a first uplink data frame) to the access point device 101 within the TXOP, the access point device 101 can obtain the first radio frame by carrying the first identification information in the PHY preamble of the block acknowledgment frame BA frame of the first uplink data frame, indicating that the access point device 101 will send the first non-low-latency service data to the site device 102.

[0137] Step 202: The access point device 101 sends the first wireless frame to the site device 102, instructing the site device 102 (i.e., the receiver of the first wireless frame) to determine whether to perform delayed feedback on the first non-low-latency service data after the first low-latency service data transmission is completed.

[0138] In some embodiments, when the access point device 101 sends the first non-low-latency service data to the site device 102 (that is, the first non-low-latency service data is the downlink data frame), the access point device 101 sends the first radio frame to the site device 102, instructing the site device 102 to perform delayed feedback on the first non-low-latency service data after the first low-latency service data transmission is completed;

[0139] In some embodiments, when the access point device receives the first non-low-latency service data sent by the site device 102 (that is, the first non-low-latency service data is the first uplink data frame), the access point device 101 sends the first wireless frame to the site device 102, instructing the site device 102 not to delay feedback of the first non-low-latency service data after the transmission of the first low-latency service data is completed.

[0140] Step 203: The access point device 101 sends the first low-latency service data to the site device 102.

[0141] In some embodiments, the first low-latency service data includes a first data frame and a second data frame; during the transmission of the first low-latency service data, the second data frame can be transmitted after the transmission of the first data frame is completed and the interval point coordination function inter-frame interval PIFS or short inter-frame interval SIFS is completed, so as to avoid the transmission process of the second data frame interfering with the transmission process of the first data frame.

[0142] It can be understood that the first low-latency service data may include one or more data frames. When the first low-latency service data includes multiple data frames, the next data frame can be transmitted in the order of the data frames after the previous data frame is transmitted and after an interval of PIFS or SIFS, until every data frame in the first low-latency service data is transmitted.

[0143] Step 204: After the first low-latency service data transmission is completed, the site device 102 determines whether to perform delayed feedback on the first non-low-latency service data based on the received first radio frame.

[0144] Optionally, when determining to perform delayed feedback on the first non-low-latency service data, the feedback information may include information on the reception status of the transmitted first non-low-latency service data before the first low-latency service is sent.

[0145] In some embodiments, step 204 may include step 2041 and step 2042 .

[0146] Step 2041: When the access point device 101 sends the first non-low-latency service data to the site device 102 (that is, the first non-low-latency service data is the downlink data frame), after the access point device 101 sends the first wireless frame to the site device 102, the site device 102 determines that after receiving the first low-latency service data sent by the access point device 101, it delays feedback on the first non-low-latency service data.

[0147] Step 2042: When the access point device receives the first non-low-latency service data sent by the site device 102 (that is, the first non-low-latency service data is the first uplink data frame), the access point device 101 sends the first wireless frame to the site device 102, and the site device 102 determines that after receiving the first low-latency service data sent by the access point device 101, it does not delay feedback for the first non-low-latency service data.

[0148] Step 205: After the first low-latency service data transmission is completed, the first non-low-latency service data transmission may continue. After the first low-latency service data transmission is completed, if the first non-low-latency service data transmission is not completed, the first non-low-latency service data transmission may continue.

[0149] As an example, when the first non-low-latency service data includes a third data frame and a fourth data frame, and the first non-low-latency service data is a downlink data frame, the access point device 101 can carry the first identification information in the PHY preamble of the third data frame when sending the third data frame to the site device 102 to obtain the first radio frame; send the first radio frame to the site device 102, and send the first low-latency service data to the site device 102; after the access point device 101 completes sending the first low-latency service data to the site device 102, the site device 102 sends a BA frame for the third data frame to the access point device 101 (that is, delay feedback on the third data frame); after receiving the BA frame for the third data frame, the access point device 101 sends a fourth data frame to the site device 102.

[0150] As another example, when the first non-low-latency service data includes a third data frame and a fourth data frame, and the first non-low-latency service data is an uplink data frame, the access point device 101 can receive the third data frame sent by the site device 102 and, when providing feedback on the third data frame, carry the first identification information in the BA frame of the third data frame to obtain the first radio frame; send the first radio frame to the site device 102, and send the first low-latency service data to the site device 102; after the access point device 101 completes sending the first low-latency service data to the site device 102, the site device 102 sends the fourth data frame to the access point device 101 (i.e., the site device 102 does not provide delayed feedback on the third data frame).

[0151] In some embodiments, the sender of the first non-low-latency service data uses enhanced distributed coordinated access (EDCA) to reacquire the transmission opportunity TXOP, and continues to transmit the first non-low-latency service data within the reacquired TXOP.

[0152] Optionally, since the original TXOP required for transmitting the first non-low-latency service data will be occupied when the access point device 101 and the site device 102 transmit the first low-latency service data, if after the transmission of the first low-latency service data is completed, the transmission process of the first non-low-latency service data that has not been transmitted cannot be completed within the remaining duration of the original TXOP, the sender of the first non-low-latency service data can use EDCA to re-acquire the transmission opportunity TXOP, and continue to complete the transmission process of the first non-low-latency service data that has not been transmitted within the re-acquired TXOP, to ensure that the first non-low-latency service data can be transmitted successfully.

[0153] Step 206: The site device 102 may determine a second radio frame during the process of transmitting the second non-low-latency service data with the access point device 101; wherein the second radio frame includes second identification information, and the second identification information indicates that the second low-latency service data is transmitted after the second radio frame is transmitted. Specifically:

[0154] When the site device 102 sends the second non-low-latency service data to the access point device 101, and the second non-low-latency service data is a second uplink data frame, the site device 102 can obtain the second radio frame by carrying the second identification information in the PHY preamble of the second uplink data frame, indicating that the site device 102 will send the second non-low-latency service data to the access point device 101.

[0155] Step 207: The site device 102 sends a second radio frame to the access point device 101, instructing the access point device 101 to perform delayed feedback on the second non-low-latency service data after the second low-latency service data transmission is completed.

[0156] Step 208 : The site device 102 sends the second low-latency service data to the access point device 101 .

[0157] In some embodiments, the second low-latency service data includes a fifth data frame and a sixth data frame; in the process of the site device 102 sending the first low-latency service data to the access point device 101, the site device 102 may send the fifth data frame to the access point device 101, and after an interval of PIFS or SIFS, send the sixth data frame to the access point device 101 to avoid the transmission process of the sixth data frame interfering with the transmission process of the fifth data frame.

[0158] It can be understood that the second low-latency service data may also include one or more data frames. In the case that the second low-latency service data includes multiple data frames, the next data frame can be transmitted in the order of the data frames after the previous data frame is transmitted and after an interval of PIFS or SIFS, until every data frame in the second low-latency service data is transmitted.

[0159] Step 209: After the second low-latency service data transmission is completed, the access point device 101 performs delayed feedback on the second non-low-latency service data.

[0160] Optionally, after the site device 102 completes sending the second low-latency service data to the access point device 101, the access point device 101 sends a BA frame for the second non-low-latency service data to the site device 102 to implement delayed feedback on the second non-low-latency service data.

[0161] Step 210 : After completing sending the second low-latency service data to the access point device 101 , the site device 102 may continue to send the second non-low-latency service data to the access point device 101 .

[0162] As an example, when the second non-low-latency service data includes the seventh data frame and the eighth data frame, and the second non-low-latency service data is the second uplink data frame, the site device 102 can carry the second identification information in the PHY preamble of the seventh data frame when sending the seventh data frame to the access point device 101 to obtain the second radio frame; send the second radio frame to the access point device 101, and transmit the first low-latency service data with the access point device 101; after the access point device 101 and the site device 102 complete the transmission of the first low-latency service data, the access point device 101 sends a BA frame for the seventh data frame to the site device 102 (that is, delay feedback on the seventh data frame); after receiving the BA frame for the third data frame, the site device 102 sends the eighth data frame to the access point device 101.

[0163] In some embodiments, the sender of the second non-low-latency service data uses enhanced distributed coordinated access (EDCA) to reacquire the transmission opportunity TXOP, and continues to transmit the second non-low-latency service data within the reacquired TXOP.

[0164] Optionally, since the second low-latency service data is transmitted between the access point device 101 and the site device 102, the second original TXOP required for transmitting the second non-low-latency service data will be occupied, if after the transmission of the second low-latency service data is completed, the transmission process of the untransmitted second non-low-latency service data cannot be completed within the remaining duration of the second original TXOP, the sender of the second non-low-latency service data can use EDCA to re-acquire TXOP, and continue to complete the transmission process of the untransmitted second non-low-latency service data within the re-acquired second TXOP, to ensure that the second non-low-latency service data can be transmitted successfully.
