[0039] This disclosure presents a communication method, communication device, and communication system.

[0040] In a first aspect, embodiments of this disclosure provide a communication method applied to a first device, the method comprising:

[0041] A first wireless frame is determined; wherein, the first wireless frame includes first identification information, the first identification information identifying: when there is a coexisting IDC service that needs to be transmitted within the device in the current transmission opportunity TXOP, the first device occupies the TXOP to perform wireless fidelity Wi-Fi service transmission for a first duration;

[0042] Send the first wireless frame.

[0043] In the above embodiments, the first device determines and sends a first wireless frame; wherein, the first wireless frame includes first identification information, the first identification information identifying: when there is a coexisting IDC service that needs to be transmitted within the device in the current transmission opportunity TXOP, the first device occupies the TXOP to perform a first duration of Wi-Fi service transmission, so that when the IDC service and the Wi-Fi service being transmitted overlap, the efficiency and reliability of the Wi-Fi service when sharing the TXOP are ensured, and the UHR requirement is met.

[0044] In conjunction with some embodiments of the first aspect, in some embodiments, when the first wireless frame includes a Physical Layer Protocol Data (PPDU) frame or a Media Access Control Protocol Data (MPDU) frame, and the service transmission duration of the IDC service is within the duration of the TXOP, the first duration information is set as follows:

[0045] The duration required to send the first wireless frame;

[0046] or,

[0047] The sum of the duration required to transmit the first wireless frame and the second duration; wherein the second duration includes any one or more of the following:

[0048] The duration of the wireless frames transmitted after the first wireless frame, and the duration of receiving and / or transmitting acknowledgment frames.

[0049] In the above embodiments, the first duration information is set to the duration required for the currently transmitted PPDU or MPDU frame, excluding the duration required for subsequent transmission of other PPDU or MPDU frames; that is, the duration required for the currently transmitted PPDU or MPDU frame is determined to declare the duration for occupying resources within the current TXOP for Wi-Fi service transmission, ensuring that Wi-Fi service can be transmitted within this duration; the first duration information is set to the sum of the duration required for the first wireless frame, the duration for subsequent transmission of other wireless frames, and the duration for receiving and replying to acknowledgment frames; this is suitable for scenarios requiring high throughput and continuous transmission of large amounts of data; in this scenario, by transmitting multiple PPDU or MPDU frames within the TXOP, communication efficiency can be improved and the overhead caused by channel contention can be reduced.

[0050] In conjunction with some embodiments of the first aspect, in some embodiments, when the first wireless frame includes a control frame and the service duration of the IDC service is within the duration of the TXOP, the first identification information is set to a first parameter value.

[0051] In the above embodiments, since the transmission of control frames (ACK frames or BA frames) is usually completed within a short time, there is no need to reserve time for other data transmissions. Therefore, if the service transmission duration of the IDC service is within the duration of the TXOP, and the first wireless frame is a control frame, the parameter value of the first identification information is set to the first parameter value.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the first duration information is set as follows:

[0053] The "more data" field in the MAC header of the first wireless frame is set to a second parameter value, which indicates that there are still PPDU or MPDU frames to be transmitted after the first wireless frame is sent.

[0054] In the above embodiments, the parameter value of the more data field in the MAC header of the PPDU frame or MPDU frame is set to the second parameter value, indicating that the first device has other PPDU frames or MPDU frames to transmit subsequently, prompting the second device to continue to maintain the receiving state, even though the transmission of the current frame is completed, subsequent frames will still be sent.

[0055] In conjunction with some embodiments of the first aspect, in some embodiments, when the first wireless frame includes a PPDU frame or an MPDU frame, and the service transmission duration of the IDC service is greater than the current remaining duration of the TXOP, the first duration information is set as follows:

[0056] The third parameter value indicates that after sending the first radio frame, the channel is re-competed for through the Enhanced Distributed Channel Access (EDCA) mechanism.

[0057] The duration required to send the first radio frame is indicated by the EDCA mechanism after the TXOP ends.

[0058] or,

[0059] The duration of the TXOP indicates the time during which the IDC service is transmitted.

[0060] In the above embodiments, if the service transmission duration of the IDC service is greater than the current remaining duration of the TXOP, and the parameter value of the first duration information is set to the third parameter value, it indicates that after sending the first wireless frame, the first device needs to re-compete for the channel through the EDCA mechanism to gain time for the transmission of the IDC service. If the service transmission duration of the IDC service is greater than the current remaining duration of the TXOP, and the first duration information is set to the duration required to send the first wireless frame, it indicates that the device will re-compete for the channel through the EDCA mechanism after the TXOP ends to ensure that the Wi-Fi service transmission can continue. If the service transmission duration of the IDC service is greater than the current remaining duration of the TXOP, and the first duration information is set to the full duration of the TXOP, it indicates that the IDC service will be transmitted within this time period.

[0061] In conjunction with some embodiments of the first aspect, in some embodiments, the first duration information is set as follows:

[0062] The more data field in the MAC header of the first wireless frame is set to the fourth parameter value, which indicates that there are PPDU or MPDU frames to be transmitted after the first wireless frame is sent.

[0063] In the above embodiments, the more data field of the MAC header of the PPDU frame or MPDU frame is set to the fourth parameter value, indicating that the first device has other PPDU frames or MPDU frames to transmit, prompting the second device to continue to receive, even though the transmission of the current frame is complete, subsequent frames will still be sent.

[0064] In conjunction with some embodiments of the first aspect, in some embodiments, the first identification information is carried in the duration field of the Media Access Control (MAC) frame header of the first radio frame.

[0065] In the above embodiments, in the case of sudden or non-periodic IDC service scenarios, the first device needs to reasonably set the duration field of the MAC frame header of its first wireless frame to ensure that Wi-Fi service and IDC service can be transmitted effectively.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, the parameter value of the TXOP field of the physical layer preamble (PHY) of the first radio frame is the same as the parameter value of the duration field.

[0067] In the above embodiments, after adjusting the duration field of the MAC layer, the TXOP time period of the physical layer must also be changed accordingly to ensure that the transmission time of the physical layer is consistent with the duration set by the MAC layer.

[0068] In conjunction with some embodiments of the first aspect, in some embodiments, the first wireless frame further includes second identification information; wherein the second identification information identifies a second duration of the IDC service.

[0069] In the above embodiments, when there is a sudden surge in IDC (Internet Data Center) service that needs to be transmitted, the second identification information is carried in the first wireless frame being transmitted. The second identification information identifies the duration of the IDC service, allowing the second device to make timely adjustments and optimize its transmission strategy.

[0070] In conjunction with some embodiments of the first aspect, in some embodiments, the second identification information is carried in a newly defined field in the MAC frame header of the first radio frame.

[0071] In the above embodiments, the second identification information can be carried in the A-control field of the MAC frame header of the first radio frame. By carrying the second identification information in the A-control field, the flexibility and reliability of information transmission can be effectively improved.

[0074] In conjunction with some embodiments of the second aspect, in some embodiments, when the first wireless frame includes a PPDU frame or an MPDU frame, and the service transmission duration of the IDC service is within the duration of the TXOP, the first duration information is set as follows:

[0075] The duration required to send the first wireless frame;

[0076] or,

[0077] The sum of the duration required to transmit the first wireless frame and the second duration; wherein the second duration includes any one or more of the following:

[0078] The duration of the wireless frames transmitted after the first wireless frame, and the duration of receiving and / or transmitting acknowledgment frames.

[0079] In conjunction with some embodiments of the second aspect, in some embodiments, when the first wireless frame includes a control frame and the service duration of the IDC service is within the duration of the TXOP, the first identification information is set to a first parameter value.

[0080] In conjunction with some embodiments of the second aspect, in some embodiments,

[0081] The more data field in the MAC header of the first wireless frame is set to the second parameter value, which indicates that there are PPDU or MPDU frames to be transmitted after the first wireless frame is sent.

[0082] In conjunction with some embodiments of the second aspect, in some embodiments, when the first wireless frame includes a PPDU frame or an MPDU frame, and the service transmission duration of the IDC service is greater than the current remaining duration of the TXOP, the first duration information is set as follows:

[0083] The third parameter value indicates that after sending the first radio frame, the channel is re-competed for through the EDCA mechanism;

[0084] The duration required to send the first radio frame is indicated by the EDCA mechanism after the TXOP ends.

[0085] or,

[0086] The duration of the TXOP indicates the time during which the IDC service is transmitted.

[0087] In conjunction with some embodiments of the second aspect, in some embodiments, the more data field of the MAC header of the first radio frame is set to a fourth parameter value, which indicates that there are PPDU frames or MPDU frames to be transmitted after the first radio frame is sent.

[0088] In conjunction with some embodiments of the second aspect, in some embodiments, the first identification information is carried in the duration field of the MAC frame header of the first radio frame.

[0089] In conjunction with some embodiments of the second aspect, in some embodiments, the parameter value of the TXOP field of the PHY preamble of the first wireless frame is the same as the parameter value of the duration field.

[0123] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0124] As shown in Figure 1, the communication system 100 includes a first device 101 and a second device 102. The first device 101 can be a Transmission Opportunity Holder (TXOP holder) or a Transmission Opportunity Responder (TXOP responder). When the first device 101 is a TXOP holder, the second device 102 is a TXOP responder; when the second device 102 is a TXOP holder, the first device 101 is a TXOP responder. The TXOP holder can be a Station (STA) or an Access Point (AP); the TXOP responder can be either a STA or an AP.

[0125] In some embodiments, the first device 101 and the second device 102 include, 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 at least one of, but is not limited to, a mobile phone, a wearable device, an IoT device that supports WiFi communication, a car with WiFi communication capabilities, 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 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.

[0126] Specifically, the first device 101 and the second device 102 can be terminal devices or network devices equipped with Wi-Fi chips. Optionally, the first device 101 and the second device 102 can support various 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 to these.

[0127] In some embodiments, the first device 101 and the second device 102 can be access points for mobile terminals to access a wired network. An AP acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to an Ethernet network. Specifically, an AP can be a terminal device or network device equipped with a Wi-Fi chip. Optionally, the AP can support various 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 to these.

[0128] Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple connections. For example, they can be represented as Access Point Multi-Link Device (AP MLD) and Non-Access Point Multi-Link Device (Non-AP MLD), respectively. AP MLD can represent an access point that supports multiple connection communication functions, and Non-AP MLD can represent a station that supports multiple connection communication functions.

[0129] It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

[0130] The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1. ​​The number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0131] The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called the Access Point (AP) device, and all other STAs in the network are associated with it. Other sites in the BSS network that are not the central site are called terminals, also known as non-AP STAs; terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between terminals and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.

[0132] Figure 2 is one of the interactive schematic diagrams of the communication method provided in this embodiment of the present disclosure. As shown in Figure 2, the above method includes:

[0133] Step 201, the first device 101 determines the first wireless frame; wherein, the first wireless frame includes first identification information, the first identification information identifying: when there is a coexisting IDC service in the device's TXOP and the current transmission opportunity needs to transmit, the first device 101 occupies the TXOP to perform a first duration of wireless fidelity Wi-Fi service transmission.

[0134] Optionally, IDC services may include Bluetooth transmission or UWB transmission, etc., and these are bursty transmissions, meaning they also need to be transmitted during Wi-Fi transmission.

[0135] In WLANs, Transmit Opportunities (TXOPs) are introduced. A TXOP refers to a bounded time period during which a device can transmit a specific type of communication. Devices compete for a TXOP, and once acquired, they can transmit frames of that specific communication type within the TXOP. These frames can be data frames, control frames, management frames, etc. When a device acquires a TXOP through channel contention, that device is called the TXOP holder. When a device sends a frame in response to a frame received from the TXOP holder during a frame exchange sequence, but does not acquire a TXOP during this process, that device is called the TXOP responder. In this embodiment, the TXOP holder can be a STA or an AP, and it can also be a multi-connection AP MLD or a non-AP MLD; this embodiment does not impose any limitations on this.

[0136] To further improve the reliability of WLAN connections under UHR, an In-Device Coexistence (IDC) mechanism is proposed. The IDC mechanism aims to optimize the coexistence of multiple communication technologies in a wireless network to reduce interference and improve overall performance. When Wi-Fi is transmitting, a sudden demand for IDC services may arise, meaning that IDC services also need to be transmitted while Wi-Fi is in progress. This sudden situation can lead to conflicts between Wi-Fi and IDC services, thus affecting the overall network performance. IDC services include Bluetooth (BT) transmission and Ultra Wide Band (UWB) transmission. Situations where IDC services need to be transmitted within the current TXOP include: the transmission duration of the IDC service is within the TXOP duration, or the transmission duration of the IDC service exceeds the current remaining duration of the TXOP. In the latter case, even though the transmission duration of the IDC service exceeds the current remaining duration of the TXOP, as much data as possible can still be transmitted within the current remaining duration of the TXOP, and any unfinished data will continue to be transmitted in the next TXOP.

[0137] In this embodiment of the disclosure, the first device determines a first wireless frame; wherein, the first wireless frame includes first identification information, the first identification information identifying: when there is a coexisting IDC service within the device's TXOP that needs to be transmitted, the first device occupies the TXOP for a first duration of Wi-Fi service transmission. That is, the duration identified in the first duration information is the length of time the first device needs to transmit Wi-Fi services within the TXOP at the current moment. The current TXOP is the TXOP time period currently being used by the first device, during which the first device will transmit Wi-Fi services.

[0138] The first radio frame can be a data frame or a control frame. Data frames include, but are not limited to, physical protocol data unit (PPDU) frames and media access control protocol data unit (MPDU) frames. Control frames include, but are not limited to, acknowledgement (ACK) frames and block acknowledgment (BA) frames.

[0139] In this embodiment of the disclosure, when an IDC service occurs, it is necessary to postpone the originally transmitted Wi-Fi service. The first device needs to determine the first duration information of the first device occupying TXOP for Wi-Fi service transmission, that is, determine the length of time required to transmit the Wi-Fi service, so as to declare the length of time to occupy resources in the current TXOP for Wi-Fi service transmission, and ensure that the Wi-Fi service can be transmitted within this length of time.

[0140] This ensures that when IDC services overlap with ongoing Wi-Fi services, the transmission stability of the Wi-Fi service is maintained, allowing the first device to dynamically adjust the transmission duration of the Wi-Fi service, avoiding performance degradation due to resource contention, and thus meeting UHR transmission requirements.

[0141] Step 202: The first device 101 sends the first wireless frame.

[0142] In this embodiment of the disclosure, the first device sends a first wireless frame to the second device. The first wireless frame includes first identification information, which identifies the duration for which the first device occupies the TXOP for Wi-Fi service transmission when there is an IDC service requiring transmission within the current TXOP.

[0143] Step 203: The second device 102 receives the first wireless frame to parse the first identification information and determine the Wi-Fi service transmission duration within the current TXOP.

[0144] In this embodiment of the present disclosure, the second device receives a first wireless frame and parses the first identification information carried in the first wireless frame to determine the Wi-Fi service transmission duration within the current TXOP. By parsing the first identification information, the second device can obtain the specific transmission duration of the Wi-Fi service, thereby assessing whether there are potential conflicts or resource contention within this time period, understanding the current network status, and thus adjusting its transmission strategy in a timely manner.

[0145] Referring to Figure 3, Figure 3 is a second interactive schematic diagram of the communication method provided in the embodiments of this disclosure.

[0146] As shown in Figure 3, the method includes the following steps:

[0147] Step 301, determine the first wireless frame; wherein, the first wireless frame includes first identification information, the first identification information identifying: when the current transmission opportunity TXOP contains coexisting IDC services that need to be transmitted within the device, the first device occupies the TXOP to perform wireless fidelity Wi-Fi service transmission for a first duration.

[0148] In some embodiments, the first duration information includes any one or a combination of any of the following (1) to (9):

[0149] (1) The duration required to send the first wireless frame;

[0150] (2) The duration required to transmit the second wireless frame; wherein the second wireless frame includes a wireless frame transmitted after the first wireless frame is transmitted;

[0151] (3) The time required to receive the confirmation frame corresponding to the first wireless frame;

[0152] (4) The time required to receive the confirmation frame corresponding to the second wireless frame;

[0153] (5) The time required to send the acknowledgment frame corresponding to the received wireless frame;

[0154] (6) The sum of the duration required to send the first wireless frame and any one or more of the durations in (2)-(5);

[0155] (7) The value of the first parameter;

[0156] (8) The value of the third parameter;

[0157] (9) The duration required to send the first wireless frame;

[0158] (10) The duration of the TXOP.

[0159] For example, the first duration information can be set to any one or any combination of the above (1), (6), (7), (8), (9), (10). For example, the first duration information can be set to the above (1), or the above (6), or the above (1) and (2), or the above (1) and (2) and (3) and (4) and (5), or the above (7), or the above (8), or the above (9), or the above (10); but it is not limited to these cases.

[0160] The following section will introduce how to set the first duration information under different circumstances to ensure that the transmission stability of the Wi-Fi service is maintained when the IDC service overlaps with the Wi-Fi service being transmitted. This allows the first device to dynamically adjust the transmission duration of the Wi-Fi service, avoid performance degradation caused by resource contention, and thus meet the UHR transmission requirements.

[0161] In this embodiment of the disclosure, if the service transmission duration of the IDC service is within the duration of the TXOP, that is, the transmission of the IDC service can be completed within the current TXOP, and the first wireless frame includes a physical layer protocol data PPDU frame or a media access control protocol data MPDU frame, then the first duration information can be set to the following case (1) or case (2):

[0162] In case (1), the first duration information (identified duration) is set to the duration required to send the first wireless frame.

[0163] Specifically, the first duration information is set to the duration required for the currently transmitted PPDU or MPDU frame, which may exclude the duration required for the subsequent transmission of other PPDU or MPDU frames; that is, the duration required for the currently transmitted PPDU or MPDU frame is determined to declare the duration for which resources are occupied within the current TXOP for Wi-Fi service transmission, ensuring that Wi-Fi service can be transmitted within this duration; while IDC service can start transmission after the PPDU or MPDU frame transmission is completed, without having to wait for a long TXOP period, to meet the transmission needs of urgent and sudden IDC services.

[0164] In case (2), the first duration information is set to: the sum of the duration required to send the first wireless frame and the second duration; wherein the second duration includes any one or more of the following:

[0165] The duration of the wireless frames transmitted after the first wireless frame, and the duration of receiving and / or transmitting acknowledgment frames.

[0166] Specifically, in order to ensure the smooth transmission of the current and subsequent PPDU or MPDU frames, the first duration information can be set to the sum of the duration required for the first radio frame, the duration for continuing to transmit other radio frames, and the duration for receiving and replying to acknowledgment frames. This is suitable for scenarios that require high throughput and continuous transmission of large amounts of data. In this scenario, by transmitting multiple PPDU or MPDU frames within the TXOP, communication efficiency can be improved and the overhead caused by channel contention can be reduced.

[0167] In some embodiments, if the service transmission duration of the IDC service is within the duration of the TXOP, and the first wireless frame includes a control frame, then the first identification information is set to a first parameter value, for example, the first parameter value is set to "0".

[0168] In this embodiment of the disclosure, since the transmission of control frames (ACK frames or BA frames) is usually completed within a short period of time, there is no need to reserve time for other data transmissions. Therefore, if the service transmission duration of the IDC service is within the duration of the TXOP, and the first wireless frame is a control frame, the parameter value of the first identification information is set to "0", and the time length required for the control frame being transmitted is determined to be "0"; that is, the time length for occupying resources for Wi-Fi service transmission within the current TXOP is declared to be "0".

[0169] In some embodiments, the first duration information is set as follows:

[0170] The duration required to send the first wireless frame;

[0171] Or the sum of the time required to send the first wireless frame, the time required to continue transmitting other wireless frames, and the time required to receive and reply with an acknowledgment frame;

[0172] In this configuration, the "more data" field in the MAC header of the first wireless frame is set to a second parameter value. This second parameter value indicates that there are still PPDU or MPDU frames to be transmitted after the first wireless frame. The transmission requirements of subsequent frames are independent of the setting of the duration field. Even if the duration field indicates a short duration, it is still necessary to pay attention to the frames that need to be transmitted later.

[0173] In this embodiment of the disclosure, when the first duration information is set to the above-mentioned case (1) or case (2), the parameter value of the more data field of the MAC frame header of the PPDU frame or MPDU frame is set to "1", indicating that the first device has other PPDU frames or MPDU frames to transmit later, prompting the second device to continue to maintain the receiving state. Although the transmission of the current frame is completed, subsequent frames will still be sent.

[0174] Step 302: Send the first wireless frame.

[0175] In this embodiment of the disclosure, the first device sends a first wireless frame to the second device. The first wireless frame includes first identification information, which identifies the duration for which the first device occupies the TXOP for Wi-Fi service transmission when there is an IDC service requiring transmission within the current TXOP.

[0176] Referring to Figure 4, Figure 4 is the third interactive schematic diagram of the communication method provided in the embodiments of this disclosure.

[0177] As shown in Figure 4, the method includes the following steps:

[0178] Step 401, determine the first wireless frame; wherein, the first wireless frame includes first identification information, the first identification information identifying: when the current transmission opportunity TXOP contains coexisting IDC services that need to be transmitted within the device, the first device occupies the TXOP to perform wireless fidelity Wi-Fi service transmission for a first duration.

[0179] In this embodiment of the disclosure, if the service transmission duration of the IDC service is greater than the current remaining duration of the TXOP, and the first wireless frame includes a Physical Layer Protocol Data (PPDU) frame or a Media Access Control Protocol Data (MPDU) frame, then the first duration information can be set to any one of the following cases (3) to (5):

[0180] In case (3), the first duration information is set to the third parameter value, indicating that after sending the first radio frame, the channel is re-competed for through the Enhanced Distributed Channel Access (EDCA) mechanism.

[0181] Specifically, if the transmission duration of the IDC service exceeds the current remaining duration of the TXOP, and the parameter value of the first duration information is set to "0", it indicates that after sending the first radio frame, the first device needs to re-compete for the channel through the EDCA mechanism to gain time for the transmission of the IDC service. The EDCA mechanism is a flow control technique in wireless networks. By dividing traffic into four priority categories, it allows high-priority data packets to acquire the channel faster; each category has different contention windows and retransmission strategies to reduce latency and improve network performance. In this embodiment, when it is necessary to gain transmission time for the IDC service, if the remaining duration of the current TXOP is insufficient and the first duration information is set to "0", the first device needs to re-compete for the channel through the EDCA mechanism to ensure successful transmission of IDC data.

[0182] Case (4) The first duration information is set to the duration required to send the first radio frame, indicating that after the TXOP ends, the channel will be re-competed for through the EDCA mechanism.

[0183] Specifically, if the service transmission duration of the IDC service is greater than the current remaining duration of TXOP, and the first duration information is set to the duration required to send the first wireless frame, then the device will compete for the channel again through the EDCA mechanism after TXOP ends, to ensure that Wi-Fi service transmission can continue.

[0184] Case (5) The first duration information is set to the duration of the TXOP, indicating that the IDC service is transmitted within the duration of the TXOP.

[0185] Specifically, if the transmission duration of the IDC service exceeds the current remaining duration of the TXOP, and the first duration information is set to the full duration of the TXOP, then the IDC service will be transmitted within this time period. Even if the remaining TXOP is insufficient to complete the IDC service, the first device still sets the first duration information to the entire TXOP duration. However, during this time period, the Wi-Fi device does not actually transmit data, but instead allows time for the IDC service to complete its transmission. The Wi-Fi transmission time is utilized to ensure that the IDC service can proceed smoothly during this period without being interrupted by Wi-Fi communication. This setting ensures that even if the demand for the IDC service exceeds the remaining duration, transmission can still be completed as much as possible within the current TXOP.

[0186] In some embodiments, the first duration information is set as follows:

[0187] The value of the third parameter;

[0188] Or the duration required to send the first wireless frame;

[0189] In this case, the more data field of the MAC frame header of the first wireless frame is set to the fourth parameter value, which indicates that there are still PPDU frames or MPDU frames to be transmitted after the first wireless frame.

[0190] In this embodiment of the disclosure, when the first duration information is set to the above-mentioned situation (3) or situation (4), the more data field of the MAC frame header of the PPDU frame or MPDU frame is set to "1", indicating that the first device has other PPDU frames or MPDU frames to transmit later, prompting the second device to continue to maintain the receiving state. Although the transmission of the current frame is completed, subsequent frames will still be sent.

[0191] Step 402: Send the first wireless frame.

[0192] In this embodiment of the disclosure, the first device sends a first wireless frame to the second device. The first wireless frame includes first identification information, which identifies the duration for which the first device occupies the TXOP for Wi-Fi service transmission when there is an IDC service requiring transmission within the current TXOP.

[0193] Referring to Figure 5, Figure 5 is the fourth interactive schematic diagram of the communication method provided in the embodiments of this disclosure.

[0194] As shown in Figure 5, the method includes the following steps:

[0195] Step 501, determine the first wireless frame; wherein, the first wireless frame includes first identification information, the first identification information identifying: when the current transmission opportunity TXOP contains coexisting IDC services that need to be transmitted within the device, the first device occupies the TXOP to perform wireless fidelity Wi-Fi service transmission for a first duration.

[0196] In some embodiments, the first identification information is carried in the duration field of the Media Access Control (MAC) header of the first wireless frame.

[0197] In this embodiment of the disclosure, under bursty or non-periodic IDC service scenarios, the first device needs to reasonably set the duration field of the MAC frame header of its first wireless frame to ensure that Wi-Fi service and IDC service can be transmitted effectively. The duration field carries information about the first duration for which the first device occupies the TXOP for Wi-Fi service transmission.

[0198] In some embodiments, the parameter value of the TXOP field of the physical layer preamble (PHY preamble) of the first radio frame is the same as the parameter value of the duration field. For example, if the parameter value of the duration field of the MAC header of the first radio frame is set to "0", then the parameter value of the PHY preamble field is also set to "0"; if the parameter value of the duration field of the MAC header of the first radio frame is set to "1", then the parameter value of the PHY preamble field is also set to "1".

[0199] In some embodiments, the PHY preamble field can be determined based on the method described above for determining the content of the duration field in the MAC frame header. However, the content can be filled only in the PHY preamble field, regardless of whether the duration field includes the content. For example, the duration field may not include the content or may include content used to indicate other content.

[0200] In some embodiments, the duration field can be determined based on the method described above for determining the content of the duration field in the MAC frame header, regardless of whether the PHY preamble field includes this content. For example, the duration field may not include this content or may include content used to indicate other content.

[0201] In this embodiment of the disclosure, after adjusting the duration field of the MAC layer, the TXOP period of the physical layer must also be changed accordingly to ensure that the transmission time of the physical layer is consistent with the duration set by the MAC layer. If the TXOP period in the PHY preamble is not adjusted, it may cause inconsistencies in the perception of transmission time between the MAC layer and the physical layer, resulting in link interruption or waste of channel resources.

[0202] In some embodiments, the first wireless frame further includes second identification information; wherein the second identification information identifies a second duration of the IDC service.

[0203] In this embodiment of the disclosure, when there is a sudden surge in IDC (Internet Data Center) service that needs to be transmitted, a second identification information is carried in the first wireless frame being transmitted. The second identification information identifies the duration of the IDC service, allowing the second device to make timely adjustments and optimize its transmission strategy.

[0204] In some embodiments, the second identification information is carried in a newly defined field in the MAC frame header of the first radio frame.

[0205] In this embodiment of the disclosure, the second identification information can be carried in the A-control field of the MAC frame header of the first wireless frame. By carrying the second identification information in the A-control field, the flexibility and reliability of information transmission can be effectively improved, enabling the second device to quickly identify the existence and duration of the IDC service.
