[0044] This disclosure presents a communication method, communication device, and communication system.

[0045] In a first aspect, embodiments of this disclosure provide a communication method applied to a first device, the method comprising:

[0046] A first wireless frame is determined; the first wireless frame includes first identification information, which identifies: within the TXOP of the first device, the first duration information required for the coexisting IDC services within the transmission device is transmitted.

[0047] Send the first wireless frame;

[0048] Prior to transmitting the IDC service, the first device transmits Wi-Fi PPDU frames in the main link and the secondary link, and the main link and the secondary link are non-simultaneous NSTR transmission and reception.

[0049] In the above embodiments, by carrying first identification information in the first wireless frame, the first identification information identifies that the first duration information of the IDC service needs to be transmitted in the TXOP of the first device, and defines a mechanism for the first device including NSTR link pairs to access the primary and secondary links respectively when the IDC service exists, which is suitable for UHR transmission requirements.

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

[0051] Within the time range specified by the first duration information, Wi-Fi service transmission in the main link and the secondary link is suspended.

[0052] In the above embodiments, to ensure the smooth operation of IDC services, the first device suspends Wi-Fi service transmission on both the main link and the secondary link within the time range indicated by the first duration information. By temporarily stopping the Wi-Fi service, the device can avoid interference, thereby prioritizing the stable transmission of IDC services.

[0053] In conjunction with some embodiments of the first aspect, in some embodiments, transmitting the first wireless frame includes:

[0054] The IDC service exists on the main link, and the first wireless frame is transmitted on the main link; and the first device sets the network allocation vector (NAV) duration of the main link to be no less than the duration identified in the first duration information; or,

[0055] The IDC service exists on the secondary link, and the first wireless frame is transmitted on the secondary link; and the first device sets the NAV duration of the secondary link to be no less than the duration identified in the first duration information.

[0056] In the above embodiment, NAV is set to notify other WLAN devices of the duration for which the WLAN device currently obtaining the channel will use the channel. Other WLAN devices that hear the frame will remain silent during this duration, i.e., stop competing for the channel.

[0057] In conjunction with some embodiments of the first aspect, in some embodiments, when the first device acts as a transmission opportunity holder (TXOP), the method further includes:

[0058] After the IDC service transmission is completed, and at least one functional inter-frame interval (PIFS) has elapsed, the first device re-competes for the channel through the enhanced distributed channel access (EDCA) mechanism, and transmits Wi-Fi PPDU frames in the main link and the secondary link.

[0059] In the above embodiments, the re-competition for the channel allows devices to compete fairly based on EDCA priority. This approach enables the rational scheduling of resource demands from various devices, even in high-load networks, thereby improving the overall channel utilization efficiency.

[0060] In conjunction with some embodiments of the first aspect, in some embodiments, when the first device acts as a Transmission Opportunity Response (TXOP) Responder, after sending the first radio frame, the method further includes:

[0061] If the duration of the first duration information identifier is within the TXOP, or if the duration of the first duration information identifier exceeds the current remaining duration of the TXOP, the first device receives Wi-Fi PPDU frames in the main link and / or the secondary link after the IDC service transmission is completed.

[0062] In the above embodiments, it is ensured that the first device can reasonably schedule the timing of Wi-Fi frame reception to avoid interference during IDC service transmission. If the first duration information is within the TXOP or exceeds the remaining time of the TXOP, the first device must wait until the IDC service ends before receiving the Wi-Fi PPDU frame to ensure the stability and reliability of data transmission.

[0063] In conjunction with some embodiments of the first aspect, in some embodiments, when the first device acts as a TXOP holder and the IDC service is a periodic IDC service, the method further includes:

[0064] The duration identified by the first duration information does not overlap with the current remaining duration of the TXOP.

[0065] In the above embodiments, separating the duration of the IDC service from the remaining duration of the TXOP enables periodic services to be transmitted within a stable, non-interference time period, while avoiding impacting the Wi-Fi service in the TXOP of the first device.

[0066] In conjunction with some embodiments of the first aspect, in some embodiments, when the first device acts as a TXOP Responder and the IDC service is a periodic IDC service, the method further includes:

[0067] The first device broadcasts the periodic IDC service.

[0068] In the above embodiments, by broadcasting periodic IDC services, the first device can effectively coordinate other devices in the network, ensuring that they take the existence of IDC services into account when transmitting data. This transparent information transmission mechanism not only reduces potential interference and conflicts and improves network resource utilization efficiency, but also enhances the cooperation capabilities between devices, ensuring the smooth coexistence of multiple services, thereby improving overall network performance and user experience.

[0069] Secondly, embodiments of this disclosure provide a communication method applied to a second device, the method comprising:

[0070] Receive a first wireless frame; the first wireless frame includes first identification information, the first identification information identifying: within the TXOP of the first device, the first device transmits first duration information required for IDC services;

[0071] Before the first device transmits the IDC service, the first device transmits Wi-Fi PPDU frames in the primary link and the secondary link, and the primary link and the secondary link are NSTRs for each other.

[0072] In the above embodiment, the second device receives a first wireless frame sent by the first device. The first wireless frame contains duration information about the IDC service within the first device's TXOP. By receiving the first wireless frame, the second device can promptly obtain information about the resource usage of the first device, thereby avoiding attempts to communicate with the first device during the transmission period of the IDC service. This not only effectively reduces inter-link interference but also improves communication stability and efficiency, ensuring the coordination of network performance.

[0073] In conjunction with some embodiments of the second aspect, in some embodiments, the method further includes:

[0074] Within the time range specified by the first duration information, Wi-Fi service transmission in the main link and the secondary link is suspended.

[0075] In conjunction with some embodiments of the second aspect, in some embodiments, receiving the first radio frame includes:

[0076] The IDC service exists on the main link, and the first wireless frame is received on the main link; and the second device sets the NAV duration of the main link to be no less than the duration identified in the first duration information; or,

[0077] The IDC service exists on the secondary link, and the first wireless frame is received on the secondary link; and the second device sets the NAV duration of the secondary link to be no less than the duration identified in the first duration information.

[0078] In conjunction with some embodiments of the second aspect, in some embodiments, when the second device acts as a TXOP Responder, after receiving the first radio frame, the method further includes:

[0079] Once the IDC service transmission is complete, Wi-Fi PPDU frames are received in the main link and the secondary link.

[0080] In conjunction with some embodiments of the second aspect, in some embodiments, when the second device acts as a TXOP holder, after receiving the first wireless frame, the method further includes:

[0081] If the duration of the first duration information identifier is within the TXOP, or if the duration of the first duration information identifier exceeds the current remaining duration of the TXOP, the second device transmits Wi-Fi PPDU frames in the main link and / or the secondary link after the IDC service transmission is completed.

[0082] In conjunction with some embodiments of the second aspect, in some embodiments, when the first device acts as a TXOP holder and the IDC service is a periodic IDC service, the method further includes:

[0083] The duration identified by the first duration information does not overlap with the current remaining duration of the TXOP.

[0084] In conjunction with some embodiments of the second aspect, in some embodiments where the first device acts as a TXOP Responder and the IDC service is a periodic IDC service, the method further includes:

[0085] Receive the periodic IDC service broadcast by the first device.

[0120] Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

[0121] As shown in Figure 1, the communication system 100 includes a first device 101 and a second device 102.

[0122] In some embodiments, the second device 102 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi 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 Wi-Fi communication, a car with Wi-Fi 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.

[0123] Specifically, the second device 102 can be a terminal device or network device with a Wi-Fi chip. Optionally, 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 is not limited to these.

[0124] In some embodiments, the first device 101 can be an access point 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.

[0125] 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.

[0126] In some embodiments, the first device 101 may be a Non-Simultaneous Transmit and Receive mobile AP MLD (NSTR mobile AP MLD), and the second device 102 may be a non-AP MLD.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0131] Step 201, the first device 101 determines the first radio frame; the first radio frame includes first identification information, the first identification information identifying: the first duration information required for transmitting in-device coexistence (IDC) services within the first device's transmission opportunity (TXOP);

[0132] Before transmitting the IDC service, the first device 101 transmits Wi-Fi Physical Layer Protocol Data Unit (Wi-Fi PPDU) frames in the main link and the secondary link, and the main link and the secondary link are NSTRs for each other.

[0133] Specifically, in WLANs, a Multi-Link Operation (MLO) mechanism is introduced to achieve higher throughput and lower network latency. Further, a device supporting MLO is called a Multi-Link Device (MLD). An NSTR mobile AP MLD is a form of mobile access point (Mobile AP) that supports multi-link operation and the NSTR mechanism. In this embodiment, the link established between the NSTR mobile AP MLD and the non-AP MLD is an NSTR link pair, including a primary link and a secondary link (or non-primary link). Specifically, in the NSTR mechanism, interference exists between links; when transmitting on one link, transmitting or receiving on other links is impossible. For example, when the primary link is idle, the primary and secondary links can communicate simultaneously; however, when the primary link is busy, even if the secondary link is idle, communication is impossible. Optionally, in this embodiment, the first device can be an NSTR mobile AP MLD.

[0134] Furthermore, a TXOP mechanism is introduced in WLAN. Specifically, a TXOP refers to a bounded time period during which a device can transmit a specific type of communication. Devices acquire TXOPs through contention, and once acquired, they can transmit frames of a specific type of communication within the TXOP; these frames can specifically be data frames, control frames, and management frames, etc. Optionally, when a device acquires a TXOP through channel contention, that device is called a TXOP holder. Correspondingly, if a device transmits frames in the frame exchange sequence in response to frames received from the TXOP holder, but does not acquire a TXOP during this process, then that device is called a TXOP responder. As one implementation, in this embodiment of the disclosure, the first device, when it is an NSTR mobile AP MLD, can act as either a TXOP holder or a TXOP responder. For example, when the first device is a TXOP holder, the second device is a TXOP responder; when the first device is a TXOP responder, the second device is a TXOP holder.

[0135] Furthermore, in the UHR scenario, to further improve the reliability of WLAN connections, and considering that the device may also support the transmission of other services, such as Bluetooth (BT) or Ultra Wide Band (UWB), an 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 services are transmitting, a sudden demand for IDC services may arise; that is, IDC services need to be transmitted simultaneously with Wi-Fi transmission. This sudden situation may lead to conflicts between Wi-Fi and IDC services, thereby affecting the overall network performance and user experience. IDC services include, for example, Bluetooth (BT) transmission and Ultra Wide Band (UWB) transmission. Moreover, to further improve the reliability of wireless LAN connections, reduce latency, and lower device-level power consumption, most UHRs are configured as MLD devices. Therefore, the embodiments disclosed in this disclosure aim to further improve the IDC mechanism to adapt to UHR transmission requirements.

[0136] In this embodiment, a first device determines a first wireless frame. The first wireless frame includes first identification information, which identifies the first duration information required for transmitting a bursty IDC service (sending or receiving an IDC service) within the first device's TXOP. The primary link and the secondary link are NSTRs. Before transmitting the IDC service, the first device simultaneously transmits Wi-Fi PPDU frames in both the primary and secondary links within the TXOP. If an IDC service needs to be transmitted on either the primary or secondary link, the first device identifies the first duration information of the IDC service to be transmitted in the first wireless frame, declaring that it will occupy resources for IDC service transmission within the time specified in the first duration information. Furthermore, it is understood that the IDC service can exist on either the primary or secondary link, or simultaneously on both. If an IDC service exists on both the primary and secondary links, the IDC services on both links must also meet the transmission restrictions of the NSTR link pair; for example, the primary and secondary links can simultaneously receive or send wireless frames.

[0137] The first radio frame includes, but is not limited to, a Wi-Fi PPDU frame. This disclosure defines a transmission mechanism for a suddenly appearing IDC (Internet Data Center) service when the primary and secondary links are non-strutable links (NSTRs) and Wi-Fi services are being transmitted simultaneously. By carrying first identification information in the first radio frame, the first identifier indicates the first duration of IDC service transmission within the TXOP of the first device. This information determines the required duration for IDC service transmission, thus declaring the resources occupied within the TXOP of the first device for IDC service transmission. This ensures that the IDC service can be transmitted within this duration, avoiding conflicts between Wi-Fi and IDC services and preventing impacts on overall network performance. In this way, in an NSTR scenario, the transmission stability of the IDC service is maintained when it overlaps with an ongoing Wi-Fi service. This allows the first device to effectively manage resources, prioritizing the transmission needs of the IDC service and avoiding signal loss or transmission delays caused by Wi-Fi interference, thereby meeting UHR (Unified Relay Response) transmission requirements.

[0138] Step 202: The first device 101 sends the first wireless frame.

[0139] In this embodiment, the first device sends a first wireless frame carrying first identification information, which indicates that within the first device's TXOP, first duration information of coexisting IDC services needs to be transmitted. IDC service transmission begins after the first wireless frame is sent. By explicitly communicating the time requirements of the IDC services, the first device can prioritize resource allocation, avoiding conflicts between IDC services and Wi-Fi services, thereby improving transmission stability and meeting UHR requirements.

[0140] Step 203: The second device 102 receives the first wireless frame.

[0141] In this embodiment, the second device receives a first wireless frame sent by the first device. The first wireless frame contains duration information about the IDC service within the first device's TXOP. By receiving the first wireless frame, the second device can promptly obtain information about the resource usage of the first device, thereby avoiding attempts to communicate with the first device during the transmission period of the IDC service. This not only effectively reduces inter-link interference but also improves communication stability and efficiency, ensuring the coordination of network performance.

[0142] In this embodiment of the disclosure, the second device can be a multi-link site device (non-AP MLD).

[0143] The communication method involved in the embodiments of this disclosure may include at least one of steps 201 to 203. For example, step 201 may be implemented as a standalone embodiment, step 202 may be implemented as a standalone embodiment, step 201 + step 202 may be implemented as a standalone embodiment, and step 202 + step 203 may be implemented as a standalone embodiment, but is not limited thereto.

[0144] Figure 3 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 3, the embodiments of the present disclosure relate to a communication method, which includes:

[0145] Step 301, the first device 101 determines the first radio frame; the first radio frame includes first identification information, which identifies: the first duration information required for transmitting in-device coexistence (IDC) services within the first device's transmission opportunity (TXOP).

[0146] This disclosure defines a transmission mechanism for a suddenly appearing IDC (Internet Data Center) service when the primary and secondary links are NSTRs (Network Streaming Transmission Lines) and Wi-Fi service transmission is performed simultaneously. By carrying first identification information in the first radio frame, the first identifier indicates the first duration information required to transmit the IDC service within the TXOP (Turns and Open Frames) of the first device. This information determines the duration required to transmit the IDC service, thereby declaring the resources occupied within the TXOP of the first device for IDC service transmission.

[0147] Step 302: The IDC service exists on the main link, and the first device 101 sends the first wireless frame on the main link;

[0148] Wherein, the first device sets the duration of the Network Allocation Vector (NAV) of the main link to be no less than the duration identified in the first duration information.

[0149] In this embodiment of the disclosure, the method of sending the first wireless frame depends on the link location where the IDC service is located: if the IDC service is in the main link, the first wireless frame is sent through the main link, and the NAV duration of the main link is set to be no less than the duration indicated in the first duration information. Here, NAV in WLAN refers to the following: After a WLAN device competes for and obtains a channel, it typically sends one or more frames. When using the NAV method, the WLAN device that obtains the channel can set the NAV in the Duration field of the Media Access Control (MAC) frame header included in each frame it sends, to notify other WLAN devices the duration for which the currently obtained WLAN device will use the channel. Other WLAN devices that hear the frame will remain silent during this duration, i.e., stop competing for the channel.

[0150] This embodiment of the disclosure sets the NAV duration of the main link to be no less than the duration required for IDC services, enabling the first device to ensure that it is not interfered with by other devices during IDC service transmission. This setting method not only ensures stable transmission of IDC services but also reduces the risk of conflict between Wi-Fi services and IDC services, improves the transmission efficiency and reliability of the entire network, and meets the requirements of efficient resource allocation.

[0151] Step 303: The second device 102 receives the first wireless frame on the main link.

[0152] In this embodiment, the IDC service resides on the main link, and the second device receives the first wireless frame on the main link. The second device sets the NAV duration of the main link to be no less than the duration identified in the first duration information. By setting the NAV duration of the main link to be no less than the duration required for the IDC service, the second device can ensure that it is not interfered with by other devices during IDC service transmission. This setting method not only ensures stable transmission of the IDC service but also reduces the risk of conflict between Wi-Fi and IDC services, improves the overall network transmission efficiency and reliability, and meets the requirements for efficient resource allocation.

[0153] In some embodiments, Wi-Fi service transmission in the main link and the secondary link is suspended within the time range identified by the first duration information.

[0154] In this embodiment of the disclosure, to ensure the smooth operation of IDC services, the first device simultaneously suspends Wi-Fi service transmission on both the main link and the secondary link within the time range indicated by the first duration information. By temporarily stopping the Wi-Fi service, the device can avoid interference, thereby prioritizing the stable transmission of IDC services. This not only improves the reliability of IDC services but also reduces inter-link conflicts, ensuring overall network performance.

[0155] The communication method involved in the embodiments of this disclosure may include at least one of steps 301 to 303. For example, step 301 may be implemented as a standalone embodiment, step 302 may be implemented as a standalone embodiment, step 301 + step 302 may be implemented as a standalone embodiment, and step 302 + step 303 may be implemented as a standalone embodiment, but is not limited thereto.

[0156] Figure 4 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 4, the embodiments of the present disclosure relate to a communication method, which includes:

[0157] Step 401, the first device 101 determines the first wireless frame; the first wireless frame includes first identification information, the first identification information identifying: within the TXOP of the first device, the first duration information required for transmitting IDC services.

[0158] This disclosure defines a transmission mechanism for a suddenly appearing IDC (Internet Data Center) service when the primary and secondary links are NSTRs (Network Streaming Transmission Lines) and Wi-Fi service transmission is performed simultaneously. By carrying first identification information in the first radio frame, the first identifier indicates the first duration information required to transmit the IDC service within the TXOP (Turns and Open Frames) of the first device. This information determines the duration required to transmit the IDC service, thereby declaring the resources occupied within the TXOP of the first device for IDC service transmission.

[0159] Step 402: The IDC service exists on the secondary link, and the first radio frame is sent on the secondary link;

[0160] Wherein, the first device sets the NAV duration of the secondary link to be no less than the duration identified in the first duration information.

[0161] In this embodiment of the disclosure, if the IDC service is in the secondary link, the first radio frame is sent in the secondary link, and the NAV duration of the secondary link is set to be no less than that duration.

[0162] This embodiment of the disclosure sets the NAV duration of the secondary link to be no less than the duration required for IDC services, enabling the first device to ensure that it is not interfered with by other devices during IDC service transmission. This setting method not only ensures stable transmission of IDC services but also reduces the risk of conflict between Wi-Fi services and IDC services, improves the transmission efficiency and reliability of the entire network, and meets the requirements of efficient resource allocation.

[0163] Step 403: The second device 102 receives the first radio frame on the secondary link.

[0164] In this embodiment of the disclosure, the IDC service exists on the secondary link, and the second device receives the first wireless frame on the secondary link; and the second device 102 sets the NAV duration of the secondary link to be no less than the duration identified in the first duration information.

[0165] In this embodiment of the disclosure, by setting the NAV duration of the secondary link to be no less than the duration required for IDC services, the second device can ensure that it will not be interfered with by other devices during IDC service transmission. This setting method not only ensures stable transmission of IDC services but also reduces the risk of conflict between Wi-Fi services and IDC services, improves the transmission efficiency and reliability of the entire network, and meets the requirements of efficient resource allocation.

[0166] In some embodiments, Wi-Fi service transmission in the main link and the secondary link is suspended within the time range identified by the first duration information.

[0167] In this embodiment of the disclosure, to ensure the smooth operation of IDC services, the first device simultaneously suspends Wi-Fi service transmission on both the main link and the secondary link within the time range indicated by the first duration information. By temporarily stopping the Wi-Fi service, the device can avoid interference, thereby prioritizing the stable transmission of IDC services. This not only improves the reliability of IDC services but also reduces inter-link conflicts, ensuring overall network performance.

[0168] The communication method involved in the embodiments of this disclosure may include at least one of steps 401 to 403. For example, step 401 may be implemented as a standalone embodiment, step 402 may be implemented as a standalone embodiment, step 401 + step 402 may be implemented as a standalone embodiment, and step 402 + step 403 may be implemented as a standalone embodiment, but is not limited thereto.

[0169] Figure 5 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 5, the embodiments of the present disclosure relate to a communication method, which includes:

[0170] Step 501, the first device 101 determines the first wireless frame; the first wireless frame includes first identification information, the first identification information identifying: within the TXOP of the first device, the first duration information required for transmitting IDC services.

[0171] This disclosure defines a transmission mechanism for a suddenly appearing IDC (Internet Data Center) service when the primary and secondary links are NSTRs (Network Streaming Transmission Lines) and Wi-Fi service transmission is performed simultaneously. By carrying first identification information in the first radio frame, the first identifier indicates the first duration information required to transmit the IDC service within the TXOP (Turns and Open Frames) of the first device. This information determines the duration required to transmit the IDC service, thereby declaring the resources occupied within the TXOP of the first device for IDC service transmission.

[0172] Step 502: The IDC service exists simultaneously in the main link and the secondary link, and the first wireless frame is sent in the main link and the secondary link respectively;

[0173] Wherein, the first device sets the NAV duration of the primary link and the secondary link to be no less than the duration identified in the first duration information.

[0174] In this embodiment of the disclosure, if the IDC service exists in both the primary link and the secondary link, the first radio frame is sent in both the primary link and the secondary link respectively, and the NAV duration of the primary link and the secondary link is set to be no less than that duration.

[0175] Step 503: The second device 102 receives the first radio frame on the main link and the secondary link.

[0176] In this embodiment of the disclosure, the IDC service exists simultaneously in the main link and the secondary link, and the second device receives the first wireless frame in both the main link and the secondary link; wherein, the first wireless frame received by the second device under the main link carries duration information identifying the IDC service in the main link; the first wireless frame received by the second device under the secondary link carries duration information identifying the IDC service in the secondary link, and the second device 102 sets the NAV duration of the main link and the secondary link to be no less than the duration identified in the first duration information.

[0177] In some embodiments, Wi-Fi service transmission in the main link and the secondary link is suspended within the time range identified by the first duration information.

[0178] In this embodiment of the disclosure, when IDC services exist simultaneously on the main link and the secondary link, Wi-Fi service transmission on both the main link and the secondary link is suspended within the time range indicated by the first duration information, thereby prioritizing the stable transmission of IDC services. This not only improves the reliability of IDC services but also reduces conflicts between links, ensuring overall network performance.

[0179] The communication method involved in the embodiments of this disclosure may include at least one of steps 501 to 503. For example, step 501 may be implemented as a standalone embodiment, step 502 may be implemented as a standalone embodiment, step 501 + step 502 may be implemented as a standalone embodiment, and step 502 + step 503 may be implemented as a standalone embodiment, but is not limited thereto.

[0180] Figure 6 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 6, the embodiments of the present disclosure relate to a communication method, which includes:

[0181] Step 601: As a transmission opportunity holder (TXOP), after the completion of the IDC service transmission and at least one functional inter-frame space (PIFS) has elapsed, the first device 101 re-competes for the channel through the enhanced distributed channel access (EDCA) mechanism.

[0182] In this embodiment, when the first device acts as the TXOP holder, it begins transmitting IDC services after sending the first radio frame on the primary or secondary link. Regardless of whether the duration of the IDC service exceeds the remaining duration of the first device's TXOP, the first device re-competes for the channel on both the primary and secondary links after the IDC service transmission is completed. Specifically, after the IDC service transmission is completed and at least one PIFS interval has elapsed, the first device re-competes for the channel on both the primary and secondary links using the EDCA mechanism. The PIFS length is shorter than a typical Distributed Coordination Function (DCF) frame interval (such as DIFS, DCF Interframe Space). By using PIFS, the first device can obtain a higher priority than regular data frame transmission when re-competing. Furthermore, after the IDC service ends, the first device does not need to wait for a long period of channel idle time but can quickly participate in competition after the PIFS interval. Compared to the longer DIFS wait, PIFS shortens the waiting time, reduces the latency of resuming Wi-Fi transmission after the IDC service is completed, and improves transmission continuity. It should be noted that the reason why the first device re-competes for the channel in the primary and secondary links after the IDC service transmission is completed, regardless of whether the duration of the IDC service exceeds the remaining TXOP of the first device, is to avoid occupying channel resources for too long and improve channel utilization efficiency. For example, if the channel is not fully utilized within the remaining TXOP of the IDC service, the first device may occupy channel resources for a long time and affect the normal communication of other devices if it directly resumes Wi-Fi service transmission after the IDC service transmission is completed. Re-competing for the channel can avoid this situation, ensuring that the first device does not continuously occupy the channel and providing other devices with a fair access opportunity. On the other hand, re-competing for the channel allows devices to compete fairly based on EDCA priority. This approach enables the reasonable scheduling of resource requirements of each device even in a high-load network, thereby improving the overall channel utilization efficiency.

[0183] Step 602: The first device 101 transmits Wi-Fi PPDU frames in the main link and the secondary link.

[0184] In this embodiment, after the first device regains access to the channel via the EDCA mechanism, it can continue transmitting Wi-Fi PPDU frames on both the primary and secondary links. This re-contention method ensures that the first device can efficiently resume Wi-Fi service transmission after the IDC service ends, avoiding long waiting times and improving transmission continuity and resource utilization. This mechanism not only guarantees the smooth transmission of IDC services but also maximizes the channel occupancy efficiency of Wi-Fi services, thereby improving overall network performance.

[0185] In some embodiments, where the first device acts as a TXOP holder and the IDC service is a periodic IDC service, the method further includes:

[0186] The duration identified by the first duration information does not overlap with the current remaining duration of the TXOP.

[0187] In this embodiment, when the first device acts as the TXOP holder and the IDC service is a periodic service, the system is designed so that the duration of the first duration information identifier does not overlap with the current remaining duration of the TXOP. This is to avoid interference between the transmission of the periodic IDC service and the Wi-Fi service, while maintaining the timing consistency and stability of various services. It should be noted that periodic IDC services typically have fixed intervals and durations. If the transmission time of the IDC service overlaps with the remaining duration of the TXOP on the first device, it may cause the IDC service to interfere with the Wi-Fi transmission of the TXOP again in the next cycle. Therefore, separating the duration of the IDC service from the remaining duration of the TXOP allows the periodic service to be transmitted within a stable, non-interfering time period, while avoiding impacting the Wi-Fi service in the TXOP of the first device.

[0188] Step 603, when the second device 102 acts as a TXOP Responder, after receiving the first wireless frame, the method further includes:

[0189] Once the IDC service transmission is complete, Wi-Fi PPDU frames are received in the main link and the secondary link.

[0190] In this embodiment of the disclosure, after the second device receives the first wireless frame sent by the first device as a TXOP Responder, and waits for the IDC service transmission to complete, the second device can receive Wi-Fi PPDU frames from the first device on the main link and the secondary link.

[0191] This process design ensures that the second device can wait reasonably for the IDC service to finish, avoiding interference with the IDC service transmission. Simultaneously, once the IDC service is complete, the second device can smoothly receive Wi-Fi data from the first device, thus achieving seamless data transmission and improving the overall network communication efficiency and data transmission continuity.

[0192] The communication method involved in the embodiments of this disclosure may include at least one of steps 601 to 603. For example, step 601 may be implemented as a standalone embodiment, step 602 may be implemented as a standalone embodiment, step 601 + step 602 may be implemented as a standalone embodiment, and step 602 + step 603 may be implemented as a standalone embodiment, but is not limited thereto.

[0193] Figure 7 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 7, the embodiments of the present disclosure relate to a communication method, which includes:

[0194] Step 701, when the second device 102 acts as a TXOP holder, after receiving the first wireless frame, the method further includes:

[0195] If the duration of the first duration information identifier is within the TXOP, or if the duration of the first duration information identifier exceeds the current remaining duration of the TXOP, the second device 102 transmits Wi-Fi PPDU frames in the main link and / or the secondary link after the IDC service transmission is completed.

[0196] In this embodiment of the disclosure, within a TXOP, the second device, acting as the TXOP holder, simultaneously transmits Wi-Fi PPDU frames on both the primary and secondary links. After receiving the first radio frame from the first device, within the time range indicated by the first time information, the second device pauses transmitting Wi-Fi PPDU frames on both the primary and secondary links and begins transmitting IDC services. Specifically, when the second device acts as the TXOP holder, after receiving and processing the first radio frame, if the duration of the IDC service indicated by the first time information is within the TXOP period or exceeds the remaining duration of the first device's TXOP, the second device will resume transmitting Wi-Fi PPDU frames on the primary and / or secondary links after the IDC service is completed. This is to ensure that the IDC service has sufficient resources for stable transmission. If the duration of the IDC service indicated by the first duration information is within the first device's TXOP or exceeds the remaining duration of the first device's TXOP, directly resuming Wi-Fi PPDU frame transmission may interfere with the IDC service, leading to performance degradation. Therefore, the second device resumes Wi-Fi transmission only after the IDC service transmission is completed to avoid conflicts between different services. This process allows the second device to flexibly adjust the timing of Wi-Fi transmission, ensuring the stability of IDC service transmission while avoiding conflicts between Wi-Fi and IDC services. This not only improves network efficiency in multi-service coexistence environments but also optimizes resource allocation, enhancing the overall smoothness and reliability of communication.

[0197] Step 702, when the first device 101 acts as a TXOP Responder, after sending the first wireless frame, the method further includes:

[0198] If the duration of the first duration information identifier is within the TXOP, or if the duration of the first duration information identifier exceeds the current remaining duration of the TXOP, the first device receives Wi-Fi PPDU frames in the main link and / or the secondary link after the IDC service transmission is completed.

[0199] In this embodiment of the disclosure, when the first device acts as a TXOP Responder, after sending the first wireless frame, if the duration of the IDC service indicated by the first duration information is within the TXOP of the first device, or exceeds the remaining duration of the TXOP of the first device, the first device will start receiving Wi-Fi PPDU frames in the primary link and / or secondary link after the IDC service transmission is completed.

[0200] This setup ensures that the first device can appropriately schedule the reception of Wi-Fi frames to avoid interference during IDC service transmission. If the first duration information is within or exceeds the remaining time of the TXOP, the first device must wait until the IDC service ends before receiving Wi-Fi PPDU frames to ensure the stability and reliability of data transmission.

[0201] In some embodiments, where the first device acts as a TXOP Responder and the IDC service is a periodic IDC service, the method further includes:

[0202] The first device broadcasts the periodic IDC service.

[0203] In this embodiment of the disclosure, when the first device acts as a TXOP Responder and the IDC service is a periodic service, the first device will broadcast the periodic IDC service. This means that the first device periodically sends information about the IDC service to other devices in the network so that all relevant devices can be informed of the existence and demand for the IDC service in a timely manner.

[0204] This embodiment of the disclosure broadcasts periodic IDC (Internet Data Center) services, enabling the first device to effectively coordinate with other devices in the network, ensuring that they take the presence of IDC services into account when transmitting data. This transparent information transmission mechanism not only reduces potential interference and conflicts and improves network resource utilization efficiency, but also enhances the cooperation capabilities between devices, ensuring the smooth coexistence of multiple services, thereby improving overall network performance and user experience.

[0205] It should be noted that the embodiments of this disclosure shown in Figure 6 and Figure 7 can be combined with the process described in the embodiments of this disclosure shown in Figures 2 to 5, in which the first device sends a first wireless frame to the second device, to form a complete communication flow. By combining communication modes in different scenarios, the communication mechanism between the first device and the second device when the first device acts as both a TXOP holder and a TXOP responder is further improved, thereby enhancing the overall transmission efficiency and service scheduling flexibility of the system. For example, when the first device acts as a TXOP holder, it determines and sends a first wireless frame; the first wireless frame includes first identification information, which identifies that the first duration information required for transmitting IDC services is within the TXOP of the first device. The second device receives the first wireless frame as a TXOP responder. As another example, when the first device acts as a TXOP holder, it determines and sends a first wireless frame on the main link; the first wireless frame includes first identification information, which identifies that the first duration information required for transmitting IDC services is within the TXOP of the first device. The second device receives the first wireless frame on the main link as a TXOP responder. For example, when the first device acts as the TXOP holder, it determines and transmits a first radio frame on the secondary link. The first radio frame includes first identification information, which identifies the first duration information required for transmitting IDC services within the first device's TXOP. The second device, acting as the TXOP Responder, receives the first radio frame on the secondary link. Alternatively, when the first device acts as the TXOP holder, it determines and transmits a first radio frame simultaneously on both the primary and secondary links. The first radio frame includes first identification information, which identifies the first duration information required for transmitting IDC services within the first device's TXOP. The second device, acting as the TXOP Responder, receives the first radio frame on both the primary and secondary links.

For example, step 701 may be implemented as a standalone embodiment, step 702 may be implemented as a standalone embodiment, and step 701 + step 702 may be implemented as a standalone embodiment, but is not limited thereto.
