[0002] Currently, Wi-Fi technology research focuses on Ultra High Reliability (UHR), with the goal of improving the reliability of Wireless Local Area Networks (WLAN) connections, reducing latency, improving manageability, increasing throughput at different signal-to-noise ratio (SNR) levels, and reducing device-level power consumption.

[0003] In UHR, when a device is performing Wi-Fi communication, services on other wireless communication media may also be present. If there is communication interference from other wireless communication media, it will affect the current normal communication and increase communication latency. Therefore, it is necessary to provide a method to prevent interference between Wi-Fi communication services and services on other wireless communication media.

[0035] The embodiments of the present disclosure provide a communication method, a communication device, and a communication system.

[0036] In a first aspect, an embodiment of the present disclosure provides a communication method, the method comprising:

[0037] The transmission opportunity holder TXOP holder determines a first Wi-Fi data frame; wherein the first Wi-Fi data frame indicates whether the TXOP holder transmits other data frames of a non-periodic communication service of other wireless communication media after sending the first Wi-Fi data frame;

[0038] Send the first Wi-Fi data frame.

[0039] In the above embodiment, whether other data frames are to be transmitted is indicated in the first Wi-Fi data frame, so that the first receiving end avoids transmitting Wi-Fi data frames with the TXOP holder according to the indication, thereby preventing the Wi-Fi communication service between the TXOP holder and services of other wireless communication media from interfering with each other and causing conflicts.

[0040] In conjunction with some embodiments of the first aspect, in some embodiments, before determining the first Wi-Fi data frame, the method includes:

[0041] Sending a request to send (RTS) frame to a first receiving end of the first Wi-Fi data frame;

[0042] A Clear to Send (CTS) frame fed back by the first receiving end is received, where the CTS frame includes a first duration for transmitting the first Wi-Fi data frame.

[0043] In the above embodiment, the first duration of the first Wi-Fi data frame is transmitted through the interaction of the RTS frame and the CTS frame.

[0044] In combination with some embodiments of the first aspect, in some embodiments, the duration of the first Wi-Fi data frame is less than the first duration, and the first Wi-Fi data frame includes a first flag, and the first flag indicates whether the TXOP holder transmits the other data frames after sending the first Wi-Fi data frame.

[0045] In the above embodiment, the duration set in the duration field of the Wi-Fi data frame before other data frames are sent is less than the first duration, so that the first Wi-Fi data frame is transmitted within the first duration and other data frames may be transmitted within the remaining duration.

[0046] In combination with some embodiments of the first aspect, in some embodiments, the first identification information indicates that the TXOP holder transmits the other data frame after sending the first Wi-Fi data frame, and the first identification bit further indicates the TXOP holder: the first receiving end delays feedback of a block confirmation BA message or an confirmation ACK message.

[0047] In the above embodiment, since other data frames are interspersed in the TXOP, the TXOP holder may consider that the first receiving end delays feeding back a BA or ACK message, thereby preventing the TXOP holder from mistakenly identifying that the first Wi-Fi data frame is not successfully transmitted.

[0048] In combination with some embodiments of the first aspect, in some embodiments, the duration of the first Wi-Fi data frame is the first duration, and the first Wi-Fi data frame includes a first control field, where the first control field indicates whether the TXOP holder transmits the other data frames after sending the first Wi-Fi data frame.

[0056] In conjunction with some embodiments of the first aspect, in some embodiments, the first Wi-Fi data frame indicates that the TXOP holder transmits the other data frame after sending the first Wi-Fi data frame. After sending the first Wi-Fi data frame, the method further includes:

[0057] The other data frame is sent to a second receiving end of the other data frame.

[0058] In the above embodiment, the first receiving end avoids transmitting Wi-Fi data frames to the TXOP holder based on the identifier of the first Wi-Fi data frame, thereby avoiding interference between the Wi-Fi communication service between the TXOP holder and the service of other wireless communication media. The TXOP holder can normally send the other data frames to the second receiving end.

[0059] In conjunction with some embodiments of the first aspect, in some embodiments, after sending the other data frame to the second receiving end of the other data frame, the method further includes:

[0060] If the Wi-Fi data frame transmission between the first receiving end and the first receiving end is not completed in the current TXOP, the TXOP holder competes for the TXOP again through the enhanced distributed channel access EDCA mechanism after PIFS after the end of the current TXOP.

[0061] In the above embodiment, the TXOP holder competes for the TXOP again through EDCA after the PIFS of the current TXOP ends, and continues to transmit the uncompleted Wi-Fi data frame.

[0062] In a second aspect, an embodiment of the present disclosure provides a communication method, the method comprising:

[0064] In conjunction with some embodiments of the second aspect, in some embodiments, before receiving the first Wi-Fi data frame sent by the TXOP holder, the method includes:

[0065] Receive the RTS frame sent by the TXOP holder;

[0066] In response to the RTS frame, a CTS frame is fed back to the TXOP holder, where the CTS frame includes a first duration for transmitting the first Wi-Fi data frame.

[0067] In combination with some embodiments of the second aspect, in some embodiments, the duration of the first Wi-Fi data frame is less than the first duration, and the first Wi-Fi data frame includes a first identification bit, and the first identification bit indicates whether the TXOP holder transmits the other data frames after sending the first Wi-Fi data frame.

[0068] In combination with some embodiments of the second aspect, in some embodiments, the duration of the first Wi-Fi data frame is the first duration, and the first Wi-Fi data frame includes a first control field, where the first control field indicates whether the TXOP holder transmits the other data frames after sending the first Wi-Fi data frame.

[0069] In combination with some embodiments of the second aspect, in some embodiments, the first control field instructs the TXOP holder to transmit the other data frame after sending the first Wi-Fi data frame, and the first control field also includes a second duration for transmitting the other data frame.

[0070] In conjunction with some embodiments of the second aspect, in some embodiments, the first receiving end performs at least one of the following operations according to the first control field:

[0071] Entering the PS state within the second time period;

[0072] Waiting for the TXOP holder to send a Wi-Fi data frame again;

[0073] Set NAV to a busy state, and the busy time is: the sum of the second duration, the third duration of the confirmation message frame for the other data frame, the interval between the other data frame and the confirmation message frame, and SIFS or PIFS.

[0074] In combination with some embodiments of the second aspect, in some embodiments, the first Wi-Fi data frame indicates that after the TXOP holder sends the first Wi-Fi data frame, the other data frame is transmitted, and within the current TXOP, the Wi-Fi data frame between the first receiving end and the first receiving end is not completely transmitted.

[0106] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0107] As shown in Figure 1, the communication system 100 includes a transmission opportunity holder (TXOP holder) 101, a first receiving end 102, and a second receiving end 103. In the embodiment of the present disclosure, the TXOP holder 101, the first receiving end 102, and the second receiving end 103 can each be a station device (STA) or an access point device (AP), and the embodiment of the present disclosure does not limit this.

[0108] In some embodiments, the site device 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 function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, and a wireless terminal device in a smart home.

[0109] Specifically, the station device may be a terminal device or network device with a Wireless Fidelity (WiFi) chip. Optionally, the station device may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next generation 802.11 protocol, but is not limited thereto.

[0110] In some embodiments, the access point device 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, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.

[0111] 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.

[0112] 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.

[0113] 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.

[0114] 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.

[0115] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0116] In step 201, TXOP holder 101 sends a request to send (RTS) frame.

[0117] In WLAN (Wireless Local Area Network) communication scenarios, in addition to supporting Wi-Fi wireless communication media, STAs or APs may also support other wireless communication media, such as one or more of Bluetooth (BT), New Radio (NR), Long Time Evolution (LTE), Ultra Wide Band (UWB), and Zigbee. When a device is performing Wi-Fi communication, periodic or non-periodic communication tasks of other communication media (hereinafter referred to as other communication services) will be generated. That is, there is a situation where multiple communication media coexist at the same time. When multiple wireless communication media use the same frequency for communication, co-frequency interference will be generated, thereby reducing system throughput, increasing communication latency, and hindering the transmission of communication services.

[0118] It can be understood that in the embodiments of the present disclosure, other communication services may be non-periodic communication services, such as temporary communication services or bursty communication services.

[0119] Furthermore, in WLAN communication scenarios, there is a Transmit Opportunity (TXOP) mechanism. A TXOP refers to a bounded time period during which a device can transmit a specific communication category. A device obtains a TXOP through competition. Once a TXOP is obtained, the device can transmit frames of a specific communication category within the TXOP; frames can specifically be data frames, control frames, and management frames. When a device obtains a TXOP through channel competition, the device is called a TXOP holder. A device sends a frame in a frame exchange sequence in response to a frame received from a TXOP holder, but the STA does not obtain a TXOP during this process. The device is called a TXOP responder.

[0120] In a TXOP, the TXOP holder acts as the data transmitter. Before sending a Wi-Fi data frame, the TXOP holder, after competing for a channel, broadcasts a request to send (RTS) frame. The RTS frame contains a network allocation vector (NAV) (hereinafter referred to as NAV1) to indicate that the TXOP holder is to send data frames to a Wi-Fi data receiver (hereinafter referred to as the first receiver) within the duration indicated by NAV1. The duration field of the RTS frame is set to the sum of the duration of the first Wi-Fi data frame to be transmitted, two SIFSs, the duration of an acknowledgment (ACK) frame or a block acknowledgment (BA), and the duration of a clear to send (CTS) frame. The two short interframe spaces (SIFS) are, for example, the SIFS between the first receiver receiving the RTS frame and sending the clear to send (CTS) frame, and the SIFS between the first receiver receiving the first Wi-Fi data frame and replying with an ACK or BA.

[0121] It can be understood that, in the implementation of the present disclosure, "transmission" includes at least one of "sending" and "receiving".

[0122] Step 202: The first receiving end 102 sends a CTS frame to the TXOP holder; the CTS frame includes a first duration for transmitting the first Wi-Fi data frame.

[0123] After receiving the RTS, the first receiving end 102 sends a CTS frame to the TXOP holder after an interval of one SIFS. The CTS frame is used to confirm that the first receiving end 102 allows the TXOP holder to send the Wi-Fi data frame. The duration field of the CTS frame is set to: the sum of the duration of the first Wi-Fi data frame to be transmitted (the first duration), 2 SIFS, and the duration of the ACK frame or BA; wherein the two short interframe spaces (SIFS) are, for example, the SIFS between the TXOP holder receiving the CTS frame and sending the first Wi-Fi data frame, and the SIFS between the first receiving end receiving the first Wi-Fi data frame and replying to the ACK or BA.

[0124] It is understandable that the first duration may be different from the duration of the first Wi-Fi data frame to be transmitted in the RTS frame.

[0125] Step 203 : TXOP holder 101 determines a first Wi-Fi data frame. The first Wi-Fi data frame identifies whether the TXOP holder transmits other data frames of aperiodic communication services of other wireless communication media after sending the first Wi-Fi data frame.

[0126] After the interaction of RTS and CTS is completed, the TXOP holder can send the first Wi-Fi data frame to the first receiving end. Before sending the first Wi-Fi data frame, the TXOP holder may have non-periodic communication services of other wireless communication media that need to be transmitted; specifically, there are non-periodic communication services of other wireless communication media, for example, after the TXOP holder receives the CTS frame, there are other co-existing wireless communication technologies that need to send or receive non-periodic services; or there are non-periodic communication services of other wireless communication media, for example, the transmission time of other co-existing wireless communication technologies and Wi-Fi services at least partially overlaps. Among them, the communication services of other wireless communication media are, for example, one or more of the aforementioned BT technology, NR technology, LTE technology, UWB technology, and Zigbee technology.

[0127] Therefore, before sending the first Wi-Fi data frame, the TXOP holder first determines whether to transmit other data frames of aperiodic communication services on other wireless communication media after sending the first Wi-Fi data frame. The TXOP holder also identifies whether to transmit other data frames in the first Wi-Fi data frame. This allows the first receiving end to avoid transmitting Wi-Fi data frames with the TXOP holder based on the identifier, thereby preventing interference and conflict between the Wi-Fi communication services with the TXOP holder and services on other wireless communication media.

[0128] Step 204: The TXOP holder sends a first Wi-Fi data frame to the first receiving end.

[0129] The first receiving end receives the first Wi-Fi data frame and avoids transmitting the Wi-Fi data frame with the TXOP holder according to the identifier thereof, thereby preventing the Wi-Fi communication service with the TXOP holder from interfering with services of other wireless communication media.

[0130] Step 205: If the first Wi-Fi data frame indicates that the TXOP holder transmits other data frames of aperiodic communication services of other wireless communication media after sending the first Wi-Fi data frame, the TXOP holder sends the other data frames to the second receiving end.

[0131] During Wi-Fi communication, if the TXOP holder needs to communicate (send or receive) with other communication technologies, and if no rules are followed to avoid this, the Wi-Fi communication and the other communication technologies may interfere with each other. Therefore, in an embodiment of the present disclosure, if a first Wi-Fi data frame indicates that the TXOP holder transmits the first Wi-Fi data frame and then transmits other data frames of a non-periodic communication service of other wireless communication media, the first receiving end avoids transmitting Wi-Fi data frames with the TXOP holder based on the identifier of the first Wi-Fi data frame, thereby avoiding mutual interference between the Wi-Fi communication service with the TXOP holder and the service of the other wireless communication media.

[0132] In some embodiments, after sending the other data frame to the second receiving end of the other data frame, the method further includes:

[0133] If the Wi-Fi data frame transmission between the first receiving end and the first receiving end is not completed in the current TXOP, the TXOP holder competes for the TXOP again through the enhanced distributed channel access EDCA mechanism after PIFS after the end of the current TXOP.

[0134] Among them, within the current TXOP, there are still Wi-Fi data frames between the first receiving end (or other receiving end) that have not been completely transmitted, then the TXOP holder competes for the TXOP again through enhanced distributed channel access (EDCA) after PIFS (PCF interframe space, Point Coordination Function) after the end of the current TXOP, and continues to transmit the uncompleted Wi-Fi data frames, then the first receiving end receives the Wi-Fi data frames.

[0135] In some embodiments, the specific manner of identification in the first Wi-Fi data frame includes: Case 1 or Case 2:

[0136] In case 1, the duration of the first Wi-Fi data frame is less than the first duration, and the first Wi-Fi data frame includes a first identification bit, and the first identification bit indicates whether the TXOP holder transmits the other data frames after sending the first Wi-Fi data frame.

[0137] Among them, the duration set in the duration field of the Wi-Fi data frame before the other data frames are sent is less than the first duration, so that the first Wi-Fi data frame can be transmitted within the first duration and other data frames may be transmitted within the remaining duration.

[0138] The first Wi-Fi data frame also needs to add a bit to indicate that the TXOP holder has other communication technologies for communication. For example, the first identification bit is set to "1" to indicate that the other data frame is transmitted; for example, the first identification bit is set to "0" to indicate that the other data frame is not transmitted.

[0139] In some embodiments, the first identification information indicates that the TXOP holder transmits the other data frames after sending the first Wi-Fi data frame, and the first identification bit further indicates to the TXOP holder that the first receiving end delays feedback of a block acknowledgement BA message or an ACK message.

[0140] Among them, if before the TXOP holder interacts with the first receiving end with the Wi-Fi data frame, the feedback mode of the Wi-Fi data frame is set to immediate feedback, since other data frames are interspersed and transmitted in the TXOP, the TXOP holder may consider that the first receiving end delays feedback of the BA or ACK message, thereby avoiding the TXOP holder from mistakenly identifying that the first Wi-Fi data frame was not successfully transmitted.

[0141] Case 2: The duration of the first Wi-Fi data frame is the first duration, and the first Wi-Fi data frame includes a first control field, where the first control field indicates whether the TXOP holder transmits the other data frames after sending the first Wi-Fi data frame.

[0142] The duration field of a first Wi-Fi data frame before other data frames of the aperiodic communication service are transmitted is set to the same length as the first duration. A first control field is newly defined in the first Wi-Fi data frame, and the first control field is used to identify whether other communication technologies are used for communication on the TXOP holder side. For example, the first control field includes a second flag bit, and the second flag bit is set to "1" to indicate that the other data frame is being transmitted; for example, the second flag bit is set to "0" to indicate that the other data frame is not being transmitted.

[0143] In some embodiments, the first control field instructs the TXOP holder to transmit the other data frame after sending the first Wi-Fi data frame, and the first control field further includes a second duration for transmitting the other data frame.

[0144] The first control field carries the second duration for transmitting the other data frames, so that the first receiving end can determine the time for avoiding other communication technologies.

[0145] In some embodiments, the first control field indicates at least one of the following:

[0146] The first receiving end enters a power saving (PS) state within the second time period to save device power;

[0147] The first receiving end waits for the TXOP holder to send a Wi-Fi data frame again, wherein the waiting time is the sum of the second time period and one SIFS or PIFS;

[0148] The first receiving end sets the network allocation vector NAV to a busy state, and the busy time is: the sum of the second duration, the third duration of the confirmation message frame for the other data frames, the interval between the other data frames and the confirmation message frame, the short frame interval SIFS or the point coordination function frame interval PIFS; by setting the NAV of the first receiving end to a busy state, other devices are avoided from competing for the channel; wherein the busy time is: the second duration + ACK / BA duration + the interval between the other data frames and ACK / BA + SIFS / PIFS.

[0149] In the disclosed embodiment, before sending a first Wi-Fi data frame, a TXOP holder first determines whether to transmit other data frames of aperiodic communication services on other wireless communication media after sending the first Wi-Fi data frame. The first Wi-Fi data frame also indicates whether to transmit other data frames. This allows the first receiving end to avoid transmitting Wi-Fi data frames with the TXOP holder based on the identification, thereby preventing interference and conflicts between the Wi-Fi communication services with the TXOP holder and services on other wireless communication media.
