[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 Wi-Fi communication services from being interfered with by services on other wireless communication media.

[0042] The embodiments of the present disclosure provide a communication method, a communication device, and a communication system.

[0043] In a first aspect, an embodiment of the present disclosure provides a communication method, applied to a TXOP responder, the method comprising:

[0044] Receiving a first radio frame; wherein the first radio frame includes a first duration;

[0045] Determine a second radio frame; wherein the second radio frame includes a second duration, and the second duration is less than or equal to the first duration;

[0046] The second radio frame is sent.

[0047] In the above embodiment, if the TXOP responder is engaged in communication services on other wireless communication media during the first duration, the second duration field in the CTS frame is set to a value less than the first duration field, indicating that the TXOP responder needs to communicate services on other wireless communication media during the first duration. In this way, when a device is engaged in Wi-Fi communication and services on other wireless communication media are present, by setting the second duration to be less than the first duration, additional time is allocated within the first duration for transmitting services on other wireless communication media. This can temporally isolate Wi-Fi communication services from services on other wireless communication media, preventing interference between the two. This reduces interference caused by bursty communications on other wireless communication media on Wi-Fi communications, improves system throughput, and makes it suitable for UHR transmission requirements.

[0048] In combination with some embodiments of the first aspect, in some embodiments, the second duration is less than the first duration, indicating that the TXOP responder has communication services on other wireless communication media during the first duration.

[0049] In the above embodiment, when the device is performing Wi-Fi communication, if there is a service on another wireless communication medium, by setting the second duration to be shorter than the first duration, additional time is allocated within the first duration for transmitting the service on the other wireless communication medium. This can temporally isolate the Wi-Fi communication service from the service on the other wireless communication medium, thereby avoiding interference between the two.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, the second radio frame further includes a first control field;

[0051] The second duration is equal to the first duration, and the flag bit in the first control field is a reserved bit;

[0052] The second duration is shorter than the first duration, and the first control field includes communication time information of the TXOP responder performing communication services of other wireless communication media within the first duration.

[0053] In the above embodiment, the second duration is equal to the first duration, indicating that the TXOP responder does not have any communication services on other wireless communication media within the first duration. Furthermore, to ensure protocol consistency, the flag bit in the first control field is set as a reserved bit.

[0054] In the above embodiment, the second duration is less than the first duration, indicating that the TXOP responder is engaged in communication services on other wireless communication media within the first duration. Furthermore, to prevent other communication services from interfering with the current communication service during the first duration, the first control field of the CTS frame carries information about the communication time during which the TXOP responder was engaged in communication services on other wireless communication media during the first duration. This facilitates the TXOP initiator in determining the specific time of the other communication services based on the communication time information.

[0055] In conjunction with some embodiments of the first aspect, in some embodiments, the communication time information includes at least one of the following:

[0056] The start time information and end time information of the communication service;

[0057] The start time information of the communication service and the third duration of the communication service within the first duration; wherein the third duration is the difference between the first duration and the second duration;

[0058] End time information of the communication service and / or the third duration.

[0059] In the above embodiment, when the second duration is less than the first duration, the TXOP initiator can determine the time information of other communication services communicating with the TXOP responder within the first duration based on the communication time information, including the start time information, the end time information, and the third duration. This facilitates the TXOP initiator to determine the specific time of other communication services based on the communication time information and to allocate additional time within the first duration for transmitting services of other wireless communication media. This can isolate Wi-Fi communication services from services of other wireless communication media in terms of time, thereby avoiding interference between the two.

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

[0061] If the second duration is less than the first duration and a communication service of other wireless communication media exists under the first link in the NSTR link of the TXOP responder, the second link in the NSTR link stops communicating during the communication duration of the communication service.

[0062] In the above embodiment, if the TXOP responder needs to perform multi-link communication in the NSTR link, and there is communication traffic on another wireless communication medium on the first link of the NSTR link, communication on the second link of the NSTR link needs to be stopped to ensure the non-simultaneous transmission and reception performance of the NSTR link. Even if there is communication traffic on another wireless communication medium during the first duration, the TXOP responder must ensure the non-simultaneous transmission and reception performance of the NSTR link. That is, if there is communication traffic on another wireless communication medium on one link of the NSTR link, no wireless communication will be performed on the other link of the NSTR link.

[0063] In combination with some embodiments of the first aspect, in some embodiments, before sending the second radio frame, the method further includes:

[0064] First identification information is sent to the TXOP initiator, where the first identification information identifies that the TXOP responder supports communication services that transmit other wireless communication media.

[0065] In the above embodiment, the TXOP responder can describe the periodic communication service interference existing in the system through the first identification information, so that the TXOP initiator can clearly know whether the TXOP responder supports communication services transmitted on other wireless communication media, thereby reducing the probability of periodic communication service interference.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, the first radio frame includes: a request to send an RTS frame or a multi-user request to send an MU-RTS frame;

[0067] and / or

[0070] In a second aspect, an embodiment of the present disclosure provides a communication method, applied to a TXOP initiator, the method comprising:

[0071] Sending a first radio frame to the TXOP responder; wherein the first radio frame includes a first duration;

[0072] Receive a second radio frame replied by the TXOP responder; wherein the second radio frame includes a second duration, and the second duration is less than or equal to the first duration.

[0073] In combination with some embodiments of the second aspect, in some embodiments, the second duration is less than the first duration, indicating that the TXOP responder has communication services on other wireless communication media during the first duration.

[0074] In conjunction with some embodiments of the second aspect, in some embodiments, the second radio frame includes a first control field;

[0075] The second duration is equal to the first duration, and the flag bit in the first control field is a reserved bit;

[0076] The second duration is shorter than the first duration, and the first control field includes communication time information of the TXOP responder performing communication services of other wireless communication media within the first duration.

[0077] In conjunction with some embodiments of the second aspect, in some embodiments, the communication time information includes at least one of the following:

[0078] The start time information and end time information of the communication service;

[0079] The start time information of the communication service and the third duration of the communication service within the first duration; wherein the third duration is the difference between the first duration and the second duration;

[0080] End time information of the communication service and / or the third duration.

[0081] In conjunction with some embodiments of the second aspect, in some embodiments, the method further includes:

[0082] If the second duration is less than the first duration and a communication service of other wireless communication media exists under the first link in the NSTR link of the TXOP initiator, the second link in the NSTR link stops communicating during the communication duration of the communication service.

[0083] In conjunction with some embodiments of the second aspect, in some embodiments, before receiving the second radio frame replied by the TXOP responder, the method further includes:

[0118] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0119] As shown in FIG1 , a communication system 100 includes a Transmit Opportunity (TXOP) responder 101 (which may be a Station, STA or Access Point, AP) and a TXOP initiator 102 (which may be a Station, STA or Access Point, AP).

[0120] In some embodiments, the TXOP responder 101 and the TXOP initiator 102 may be, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal may be, for example, 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, or a wireless terminal device used in a smart home, but is not limited thereto.

[0121] Specifically, TXOP responder 101 and TXOP initiator 102 may be terminal devices or network devices equipped with a Wireless Fidelity (WiFi) chip. Optionally, TXOP responder 101 and TXOP initiator 102 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 are not limited thereto.

[0122] In some embodiments, the TXOP responder 101 and the TXOP initiator 102 may be access points for mobile terminals 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 may be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP may support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited thereto.

[0123] 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.

[0124] 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.

[0125] 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.

[0126] 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.

[0127] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0128] Step 201: The TXOP initiator 102 sends a first radio frame; the first radio frame includes a first duration.

[0129] In WLAN communication scenarios, the Transmit Opportunity (TXOP) mechanism is introduced. A TXOP refers to a bounded time period during which a device (such as an AP or STA) can transmit a specific communication category. For example, a STA obtains a TXOP through competition. Once a TXOP is obtained, the STA 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. During the frame exchange sequence, the TXOP holder sends frames to other devices. If the device does not obtain a TXOP during this process, the device is called a TXOP responder. Correspondingly, the TXOP holder is called a TXOP initiator.

[0130] In actual communication scenarios, STAs or APs may support other wireless communication media in addition to WiFi, such as Bluetooth (BT), New Radio (NR), Ultra Wide Band (UWB), and Zigbee. However, when multiple wireless communication media communicate using the same frequency, interference can occur, known as co-channel interference. For example, when a device simultaneously performs communication services on two or more wireless communication media, communication interference can occur. Co-channel interference reduces system throughput, increases communication latency, and hinders the transmission of communication services. Therefore, to prevent communication services from other communication media from interfering with a device's current communication medium, the co-located interference information element (IE) is defined. This IE describes periodic communication service interference within the system and the communication status of communication devices within the system. However, in UHR, both periodic and aperiodic communication service interference exist. Aperiodic communication service interference can be, for example, sudden communication service interference, and devices cannot predict sudden communication service interference using the IE.

[0131] In a TXOP, there are a TXOP initiator and a TXOP responder, wherein the TXOP initiator can be a STA or an AP.

[0132] In an embodiment of the present disclosure, optionally, the first wireless frame includes a request to send (RTS) frame or a multi-user request to send (MU RTS) frame; when the TXOP initiator is a STA, the STA sends an RTS frame to the TXOP responder (AP) after obtaining a TXOP transmission opportunity. The RTS frame is used to reserve the right to use the communication medium for use by the TXOP responder. The first duration field of the RTS frame carries information about a first duration, which is the communication time allocated by the TXOP initiator to the TXOP responder in the TXOP.

[0133] Similarly, when the TXOP initiator is an AP, after obtaining a TXOP transmission opportunity, the AP may send an MU RTS frame to at least two TXOP responders (e.g., STAs), or may send an RTS frame to only one STA. The duration field of the RTS frame or MU RTS frame carries information about a first duration, which is the communication time allocated by the TXOP initiator to the TXOP responders in the TXOP.

[0134] Optionally, the first duration can be explicitly indicated in the first duration field, for example, the first duration field directly carries the time length value; the first duration can also be implicitly indicated in the first duration field, for example, the first duration field carries an index value of the time length value.

[0135] Step 202: The TXOP responder 101 receives a first radio frame.

[0136] In the embodiments of the present disclosure, the TXOP responder may be a STA or an AP. When the TXOP responder is a STA, the STA receives a MU RTS frame or an RTS frame, obtains the first duration indication information carried in the RTS frame or the MU-RTS frame, and determines the communication time allocated by the TXOP initiator to the TXOP responder.

[0137] Step 203: The TXOP responder 101 determines a second radio frame; wherein the second radio frame includes a second duration, and the second duration is less than or equal to the first duration.

[0138] When the TXOP responder receives a first wireless frame, such as an RTS frame or an MU-RTS frame, there may be communication services of other wireless communication media during the first duration. Other wireless communication media include but are not limited to BT, NR, UWB, and Zigbee. Therefore, the TXOP responder determines a second wireless frame, such as a clear to send (CTS) frame. Therefore, in the process of determining the CTS frame, the TXOP responder carries a second duration in the CTS frame. The second duration indicates the duration of the CTS, that is, the usage time of the WiFi communication medium occupied by the TXOP responder.

[0139] The second duration is less than or equal to the first duration.

[0140] For example, if the TXOP responder is engaged in communication services on other wireless communication media during the first duration, the second duration field in the CTS frame is set to a value smaller than the first duration field, indicating that the TXOP responder needs to communicate with services on other wireless communication media during the first duration. That is, the TXOP responder will allocate a portion of the first duration for communication services on other wireless communication media. In this way, when a device is engaged in Wi-Fi communication and services on other wireless communication media are present, by setting the second duration to be smaller than the first duration and allocating additional time within the first duration for transmission of services on other wireless communication media, Wi-Fi communication services can be temporally isolated from services on other wireless communication media, preventing interference between the two. This reduces interference caused by bursty communications on other wireless communication media on Wi-Fi communications, improves system throughput, and makes it suitable for UHR transmission requirements.

[0141] If the TXOP responder does not have any communication services on other wireless communication media within the first duration, the value of the second duration field in the CTS frame can be set equal to the value of the first duration field, so that Wi-Fi communication is carried out entirely within the time allocated by the TXOP initiator to the TXOP responder, thereby effectively utilizing network transmission resources.

[0142] Step 204: The TXOP responder 101 sends the second radio frame.

[0143] The TXOP responder sends a second radio frame to the TXOP initiator to indicate the length of time the TXOP responder will occupy the radio channel.

[0144] In some embodiments, the second duration is less than the first duration, indicating that the TXOP responder has communication services on other wireless communication media during the first duration, i.e., the TXOP responder will occupy part of the first duration for communication services on other wireless communication media, thereby isolating Wi-Fi communication services from services on other wireless communication media in terms of time to avoid interference between the two.

[0145] In some embodiments, the second radio frame further includes a first control field;

[0146] The second duration is equal to the first duration, and the flag bit in the first control field is a reserved bit;

[0147] The second duration is shorter than the first duration, and the first control field includes communication time information of the TXOP responder performing communication services of other wireless communication media within the first duration.

[0148] Optionally, the second duration in the second radio frame is equal to the first duration, indicating that the TXOP responder is not interfered with by other communication media during the first duration. Therefore, to ensure consistency of the communication protocol, the flag bit in the first control field of the second radio frame is set to a reserved bit.

[0149] Optionally, if the second duration in the CTS frame is less than the first duration, the first control field of the CTS frame carries communication time information of the TXOP responder performing communication services on other wireless communication media within the first duration.

[0150] In some embodiments, when the second duration is less than the first duration, the communication time information of the communication service of other wireless communication media performed by the TXOP responder within the first duration includes the following cases 1 to 3:

[0151] Case 1: The third duration occupied by the communication service within the first duration covers the middle time period of the first duration.

[0152] Among them, the time indicated by the first control field of the second wireless frame (i.e., the third duration) covers the middle part of the time indicated by the first duration field of the first wireless frame (RTS frame or MU-RTS frame), and the communication time information includes the start time information and end time information of the communication service.

[0153] Referring to Figure 3, the time between start time 1 and end time 1 is the first duration, the time between start time 2 and end time 2 is the third duration, and the third duration covers the middle time period of the first duration. The first control field needs to record the start time information and end time information of the third duration, so that the TXOP initiator can determine the specific time of the Wi-Fi communication service (i.e., the second duration), i.e., the time period between start time 1 and start time 2, and the time period between end time 2 and end time 1.

[0154] Case 2: the third duration covers the second half of the first duration.

[0155] Among them, the time indicated by the first control field of the second radio frame is the second half of the time indicated by the first duration field of the first radio frame (RTS frame or MU-RTS frame), then the communication time information includes: the start time information of the communication service and / or the third duration occupied by the communication service within the first duration; wherein, the third duration is the difference between the first duration and the second duration. It can be understood that in the embodiment of the present disclosure, the actual communication duration of the communication service may be longer than the third duration. Optionally, the first control field can also carry the actual communication duration information of the communication service, which is not limited by the embodiment of the present disclosure.

[0156] Referring to Figure 4, the first duration is between start time 1 and end time 1, and the third duration is between start time 2 and end time 2. The third duration covers the second half of the first duration. The first control field needs to record at least one of the start time information of the communication service (start time 2) and the third duration occupied by the communication service within the first duration.

[0157] As shown in Figure 4, when the start time information (start time 2) of the communication service is recorded in the first control field, the third duration can be determined based on the start time 2 and the end time 1, and the time between the start time 2 and the end time 1 is the third duration.

[0158] When the third duration of the communication service is recorded in the first control field, the second duration can be determined according to the first duration and the third duration. The difference between the first duration and the third duration is the second duration. In addition, the start time 2 and the end time 1 can be reversed to calculate the third duration.

[0159] Optionally, in case 2, the first control field may also record the start time information and the end time information of the communication service, which is not limited in the embodiment of the present disclosure.

[0160] Case three: the third duration covers the first half of the first duration, that is, the second duration is the remaining duration after deducting the third duration from the first duration.

[0161] Among them, the time indicated by the first control field of the second radio frame covers the first half of the time indicated by the first duration field of the first radio frame (RTS frame or MU-RTS frame), and the communication time information includes: the end time information of the communication service and / or the third duration occupied by the communication service within the first duration; wherein, the third duration is the difference between the first duration and the second duration. It can be understood that in the embodiment of the present disclosure, the actual communication duration of the communication service may be longer than the third duration. Optionally, the first control field can also carry the actual communication duration information of the communication service, which is not limited by the embodiment of the present disclosure.

[0162] Referring to Figure 5, the first duration is between start time 1 and end time 1, and the third duration is between start time 2 and end time 2. The third duration covers the first half of the first duration. The first control field needs to record at least one of the end time information of the communication service (end time 2) and the third duration occupied by the communication service within the first duration.

[0163] As shown in Figure 5, when the end time information (end time 2) of the communication service is recorded in the first control field, the third duration can be determined based on the start time 1 and the end time 2. The time between the start time 1 and the end time 2 is the third duration.

[0164] When the third duration of the communication service is recorded in the first control field, the second duration can be determined based on the first duration and the third duration, and the difference between the first duration and the third duration is the second duration; in addition, by pushing the start time 1 forward by the third duration, the end time 2 can be obtained, and the end time 2 is used as the start time of the second duration.

[0165] Optionally, in case three, the first control field may also record the end time information of the communication service and the end time information (the time point in the CTS frame is consistent with the time point in the MU-RTS / RTS frame to maintain clock synchronization), which is not limited in comparison with the embodiment of the present disclosure.

[0166] In some embodiments, the method further comprises:

[0167] The second duration is less than the first duration, and a communication service of other wireless communication media exists under a first link in a non-simultaneous transmitting and receiving (NSTR) link of the TXOP responder, then the second link in the NSTR link stops communicating during the communication duration of the communication service.

[0168] In the disclosed embodiments, if a TXOP responder needs to perform multi-link operation (MLO) communication in an NSTR link, and the TXOP responder has communication traffic on other wireless communication media on the first link of the NSTR link, communication on the second link of the NSTR link needs to be stopped to ensure the non-simultaneous transmission and reception performance of the NSTR link. Even if the TXOP responder has communication traffic on other wireless communication media during the first duration, the non-simultaneous transmission and reception performance of the NSTR link must be maintained. That is, if one link of the NSTR link has communication traffic on other wireless communication media, no wireless communication is performed on the other link of the NSTR link.

[0169] In the disclosed embodiment, the co-located interference information element is used to describe periodic communication service interference within the system. In addition, by clarifying the frame structure of the first control field of the second radio frame, a mechanism for describing non-periodic communication service interference is established. This mechanism reduces the probability of sudden communication services interfering with WiFi communications, thereby improving system throughput and reducing latency.

[0170] In some embodiments, before sending the second radio frame, the method further includes:

[0171] First identification information is sent to the TXOP initiator, where the first identification information identifies that the TXOP responder supports communication services that transmit other wireless communication media.
