[0039] The embodiments of the present disclosure provide a communication method, a communication device, and a communication system.

[0040] In a first aspect, an embodiment of the present disclosure provides a communication method, applied to a site device, the method comprising:

[0041] The station device determines a CTS frame; wherein the CTS frame is sent in response to the MU-RTS frame; the CTS frame identifies whether the station device: has a non-periodic communication service of other wireless communication media;

[0042] The CTS frame is sent.

[0043] In the above embodiment, if a station device has a non-periodic communication task of other wireless communication media under the link for communicating with the access point device, the station device identifies it through a CTS frame and sends a CTS frame to the access point device. This can temporally isolate the Wi-Fi communication service from the service of the other wireless communication media to avoid interference between the two, thereby reducing the interference of bursty communications of other wireless communication media on Wi-Fi communication, improving system throughput, and making it suitable for UHR transmission requirements.

[0044] In combination with some embodiments of the first aspect, in some embodiments, the value of the first initial scrambling code SCRAMBLER_INITIAL_VALUE parameter in the sending matrix of the CTS frame is different from the value of the second SCRAMBLER_INITIAL_VALUE parameter in the receiving matrix of the MU-RTS frame, indicating that the site device has the non-periodic communication service;

[0045] or

[0046] The value of the first SCRAMBLER_INITIAL_VALUE parameter is the same as the value of the second SCRAMBLER_INITIAL_VALUE parameter, indicating that the non-periodic communication service does not exist in the site device.

[0047] In the above embodiment, when the value of the first SCRAMBLER_INITIAL_VALUE parameter in the transmission matrix of the CTS frame is different from the value of the second SCRAMBLER_INITIAL_VALUE parameter in the reception matrix of the MU-RTS frame, it is indicated that the site device has a non-periodic communication service, which indicates that in the current scenario, the site device has a communication task for other communication media; when the value of the first SCRAMBLER_INITIAL_VALUE parameter is the same as the value of the second SCRAMBLER_INITIAL_VALUE parameter, it is indicated that the site device does not have the said non-periodic communication service, which indicates that in the current scenario, the site device does not have a communication task for other communication media. Therefore, the site device instructs the access point device through the CTS frame to identify the non-periodic communication service of the site device by comparing the value of the SCRAMBLER_INITIAL_VALUE parameter, and then performs communication adjustment to improve the anti-interference capability of the communication system.

[0048] In combination with some embodiments of the first aspect, in some embodiments, the CTS frame includes newly added identification information, and the newly added identification information is set to a first parameter value, indicating that the site device does not have the non-periodic communication service; or, the newly added identification information is set to a second parameter value, indicating that the site device has the non-periodic communication service.

[0049] In the above embodiment, a station device can identify the presence of aperiodic communication traffic by defining the frame format of a CTS frame. For example, additional identification information is added to the CTS frame. When the identification information is set to a first parameter value, it indicates that the station device does not have aperiodic communication traffic; when the identification information is set to a second parameter value, it indicates that the station device does have aperiodic communication traffic. By redefining the structure of the CTS frame and adding the identification information, the purpose of sending the CTS frame can be indicated to the station device at the physical layer, enabling the identification and management of aperiodic communication traffic, reducing interference with Wi-Fi communications caused by bursty communications from other wireless communication media, and improving system throughput to meet the transmission requirements of UHR.

[0051] A downlink multi-user physical layer control protocol data unit (DL MU PPDU) frame or a trigger frame sent by an access point device is received; wherein the DL MU PPDU frame or the trigger frame includes identification information of the station device.

[0052] In the above embodiment, the station device identifies the absence of the aperiodic communication service on the station device through a CTS frame, and then receives a DL MU PPDU frame or a trigger frame sent by the access point device. The DL MU PPDU frame or the trigger frame includes identification information of the station device, which helps to improve channel utilization, reduce interference, and thus improve overall communication quality.

[0053] In conjunction with some embodiments of the first aspect, in some embodiments, the CTS frame indicates that the station device has the non-periodic communication service, and the method further includes:

[0054] The receiving access point device resends the multi-user request to send MU-RTS frame through the enhanced distributed channel access EDCA mode.

[0055] In the above embodiment, if the CTS frame indicates that the site device has the non-periodic communication service, the MU-RTS frame is re-sent by the receiving access point device in the channel obtained by re-competition in the EDCA mode, thereby realizing uplink and downlink data interaction, which helps to reduce the waiting time of non-periodic communication and improve the channel utilization of the communication network.

[0056] In a second aspect, an embodiment of the present disclosure provides a communication method, applied to an access point device, the method comprising:

[0057] The access point device sends a MU-RTS frame;

[0058] A CTS frame is received from a station device in response to the MU-RTS frame; the CTS frame identifies whether the station device has: non-periodic communication services on other wireless communication media.

[0059] In conjunction with some embodiments of the second aspect, in some embodiments, the value of the first SCRAMBLER_INITIAL_VALUE parameter in the sending matrix of the CTS frame is different from the value of the second SCRAMBLER_INITIAL_VALUE parameter in the receiving matrix of the MU-RTS frame, indicating that the site device has the non-periodic communication service;

[0060] or

[0061] The value of the first SCRAMBLER_INITIAL_VALUE parameter is the same as the value of the second SCRAMBLER_INITIAL_VALUE parameter, indicating that the non-periodic communication service does not exist in the site device.

[0062] In combination with some embodiments of the second aspect, in some embodiments, the CTS frame includes newly added identification information, and the newly added identification information is set to a first parameter value, indicating that the non-periodic communication service does not exist in the site device; or, the newly added identification information is set to a second parameter value, indicating that the non-periodic communication service exists in the site device.

[0063] In conjunction with some embodiments of the second aspect, in some embodiments, after the receiving site device sends a CTS frame in response to the MU-RTS frame, the method further includes:

[0064] Send DL MU PPDU frame or trigger frame;

[0065] The CTS frame indicates that the station device does not have the non-periodic communication service, and the DL MU PPDU frame or trigger frame includes identification information of the station device; or

[0066] The CTS frame identifies that the station device has the non-periodic communication service, and the DL MU PPDU frame or the trigger frame does not include identification information of the station device.

[0067] In conjunction with some embodiments of the second aspect, in some embodiments, after the receiving site device sends a CTS frame in response to the MU-RTS frame, the method further includes:

[0068] The CTS frame indicates that the station device has the non-periodic communication service, competes for a channel again through EDCA, and sends an MU-RTS frame to the station device.

[0069] In a third aspect, an embodiment of the present disclosure further provides a communication device, which is a site device, and the site device includes at least one of a determination module and a sending module; wherein the site device is used to execute the optional implementation method of the first aspect.

[0099] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0100] As shown in FIG1 , a communication system 100 includes a station device (STA) 101 and an access point device (AP) 102 .

[0101] In some embodiments, the station device 101 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 is, for example, at least one of a mobile phone, a wearable device, an Internet of Things device that supports Wi-Fi communication, a car with Wi-Fi communication, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in a smart grid, a wireless terminal device used in transportation safety, a wireless terminal device used in a smart city, and a wireless terminal device used in a smart home, but is not limited thereto.

[0102] Specifically, the station device 101 may be a terminal device or a network device equipped with a wireless fidelity (Wi-Fi) chip. Optionally, the station device 101 may support multiple WLAN standards, such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as the next generation 802.11 protocol, but is not limited thereto.

[0103] In some embodiments, the access point device 102 can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.

[0104] 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.

[0105] 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.

[0106] 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.

[0107] 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.

[0108] FIG2 is an interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0109] Step 201 : The station device 101 determines a Clear To Send (CTS) frame, where the CTS frame indicates whether the station device 101 has a non-periodic communication service on other wireless communication media.

[0110] In WLAN (Wireless Local Area Network) communication scenarios, STAs or APs may support other wireless communication media in addition to Wi-Fi, such as Bluetooth (BT), New Radio (NR), Long Time Evolution (LTE), Ultra Wide Band (UWB), and Zigbee. When a device is performing Wi-Fi communication, it may generate periodic or aperiodic communication tasks using other communication media. This means that multiple communication media may coexist at the same time. When multiple wireless communication media communicate using the same frequency, they may generate co-frequency interference, which reduces system throughput, increases communication latency, and hinders the transmission of communication services.

[0111] It can be understood that, in the embodiments of the present disclosure, the non-periodic communication service is, for example, a temporary communication service or a bursty communication service.

[0112] The STA determines a CTS frame and uses the CTS frame to identify whether the STA: has non-periodic communication services on other wireless communication media; specifically, the presence of non-periodic communication services on other wireless communication media, for example, after the STA sends the CTS frame, other co-existing wireless communication technologies need to send or receive non-periodic services; or the presence of non-periodic communication services on other wireless communication media, for example, other co-existing wireless communication technologies at least partially overlap in transmission time with Wi-Fi services. The communication services of other wireless communication media include one or more of the aforementioned BT technology, NR technology, LTE technology, UWB technology, and Zigbee technology.

[0113] The CTS frame is sent in response to a Multi-user Request to Send (MU-RTS) frame.

[0114] Optionally, before step 201, the access point device sends a Multi-user Request to Send (MU-RTS) frame. In a multi-user scenario, multiple STAs may request to send data frames simultaneously. By sending MU-RTS frames, the access point device can process requests from multiple STAs and simultaneously perform uplink or downlink communications with multiple STAs, thereby reducing channel contention and improving channel utilization.

[0115] Optionally, the MU-RTS frame contains identification information of multiple STAs, such as an Association Identifier (AID). In the MU-RTS frame, the Receiver Address (RA) is set to a broadcast address, which indicates that the MU-RTS frame will be sent to all STAs in the network, ensuring that all STAs can receive the MU-RTS frame, thereby coordinating data transmission between multiple devices.

[0116] However, for STAs in a multi-user scenario, after receiving the MU-RTS frame sent by the AP, there may be non-periodic communication services of other wireless communication media, such as burst communication services of other wireless communication media or temporary communication services of other wireless communication media. In the embodiment of the present disclosure, when responding to the MU-RTS frame, the STA uses a CTS frame to indicate that there are non-periodic communication services of other wireless communication media that need to be transmitted, so that the AP is informed of the above information; this avoids the situation where the AP still sends a multi-user physical layer control protocol data unit (DL MU PPDU) frame or trigger frame to the STA when there are non-periodic communication services of other wireless communication media that need to be transmitted, resulting in a waste of signaling resources, thereby reducing the system throughput, increasing communication latency, and being detrimental to the transmission of communication services.

[0117] In the embodiment of the present disclosure, when the AP determines through the CTS frame that a certain STA has non-periodic communication services on other wireless communication media that need to be transmitted, it will no longer send DL MU PPDUs or triggers to the STA, thereby avoiding interference and conflict between the STA's Wi-Fi communication services and services on other wireless communication media.

[0118] Step 202: The site device 101 sends the CTS frame.

[0119] In some embodiments, the STA sends a CTS frame. If, after sending the CTS frame, the STA has non-periodic communication services of other communication media that need to be transmitted, it is marked in the CTS frame; or if the transmission time of other coexisting wireless communication technologies and Wi-Fi services at least partially overlaps, it is marked in the CTS frame.

[0120] Step 203: The access point device 102 receives the CTS frame.

[0121] In some embodiments, the access point device receives a CTS frame and determines, based on the CTS frame, whether the STA has non-periodic communication services on other wireless communication media that need to be transmitted.

[0122] In some embodiments of the present disclosure, the CTS frame indicates that the STA does not have the non-periodic communication service, and the method further includes:

[0123] Receive a DL MU PPDU frame or a trigger frame sent by an AP; wherein the DL MU PPDU frame or the trigger frame includes identification information of a STA.

[0124] Optionally, in some embodiments, if the AP learns from a CTS frame that the STA has no aperiodic communication traffic to transmit on other wireless communication media, it may send a DL MU PPDU frame or a trigger frame to the STA. The DL MU PPDU frame or trigger frame includes the STA's identification information, indicating that the STA, as the receiver of the DL MU PPDU frame or trigger frame, conducts normal uplink / downlink Wi-Fi communications. Furthermore, when the STA identifies the absence of aperiodic communication traffic through a CTS frame, the AP may employ an optimization strategy more suitable for periodic communication.

[0125] In some embodiments of the present disclosure, a CTS frame identifies the presence of the aperiodic communication service by the STA, and the method further includes:

[0126] Receive the MU-RTS frame sent again by the AP using EDCA.

[0127] If the AP learns from the CTS frame that the STA has non-periodic communication services on other wireless communication media that need to be transmitted, it will compete for the channel again through the Enhanced Distributed Channel Access (EDCA) method and send an MU-RTS frame to the site device to implement uplink and downlink data exchange, which helps to reduce the waiting time of non-periodic communication and improve the channel utilization of the communication network.

[0128] If the STA has the aperiodic communication service, it receives the MU-RTS frame sent again by the AP in the channel obtained through EDCA competition, and implements uplink and downlink data interaction, which helps to reduce the waiting time of aperiodic communication and improve the channel utilization of the communication network.

[0129] As shown in FIG3 , in some embodiments of the present disclosure, the method includes:

[0130] In step 301 , the site device 101 determines a CTS frame, wherein the CTS frame is sent in response to a multi-user request to send MU-RTS frame.

[0131] In case 1, the value of the first SCRAMBLER_INITIAL_VALUE parameter in the sending matrix of the CTS frame is different from the value of the second SCRAMBLER_INITIAL_VALUE parameter in the receiving matrix of the MU-RTS frame, indicating that the site device 101 has the non-periodic communication service.

[0132] Case 2: The value of the first SCRAMBLER_INITIAL_VALUE parameter is the same as the value of the second SCRAMBLER_INITIAL_VALUE parameter, indicating that the site device 101 does not have the non-periodic communication service.

[0133] In scenario 1, when a STA receives a MU-RTS frame and has aperiodic traffic on other communication media, the STA sets the first and second SCRAMBLER_INITIAL_VALUE parameters in the CTS frame's transmit matrix to different values. The second SCRAMBLER_INITIAL_VALUE parameter is the same as the parameter in the receive matrix of the received MU-RTS frame. Thus, when the AP receives a CTS frame, based on the difference between the first and second SCRAMBLER_INITIAL_VALUE parameters, it can determine that the STA has aperiodic traffic on other communication media that needs to be transmitted.

[0134] In case 2, if the STA does not have any aperiodic communication service, the value of the first SCRAMBLER_INITIAL_VALUE parameter in the transmission matrix of the CTS frame is set to be the same as the value of the second SCRAMBLER_INITIAL_VALUE parameter. In this way, when the AP receives the CTS frame, based on the fact that the value of the first SCRAMBLER_INITIAL_VALUE parameter is the same as the value of the second SCRAMBLER_INITIAL_VALUE parameter, it can be determined that the STA does not have any aperiodic communication service that needs to be transmitted on other communication media, and then the uplink / downlink Wi-Fi communication with the STA can be carried out normally.

[0135] Optionally, SCRAMBLER_INITIAL_VALUE is the initial value used to generate a pseudorandom sequence. This pseudorandom sequence is used to scramble data during data transmission to enhance signal performance and security. This random scrambling of data reduces correlation during data transmission, minimizing interference and improving the signal's ability to resist interference.

[0136] Step 302: The site device 101 sends the CTS frame.

[0137] In some embodiments, when a STA sends a CTS frame, if the STA has non-periodic communication services on other communication media that need to be transmitted, this is indicated by the value of the SCRAMBLER_INITIAL_VALUE parameter in the transmit matrix of the CTS frame. For example, the value of the SCRAMBLER_INITIAL_VALUE parameter in the transmit matrix of the CTS frame is set to be different from the value of the SCRAMBLER_INITIAL_VALUE parameter in the receive matrix of the MU-RTS frame.

[0138] Step 303: The access point device 102 receives the CTS frame and parses the value of the first SCRAMBLER_INITIAL_VALUE parameter in the transmission matrix of the CTS frame.

[0139] Among them, if the value of the first SCRAMBLER_INITIAL_VALUE parameter in the sending matrix of the CTS frame parsed by the AP is different from the value of the second SCRAMBLER_INITIAL_VALUE parameter in the receiving matrix of the MU-RTS frame, it indicates that the STA has non-periodic communication services; if the value of the first SCRAMBLER_INITIAL_VALUE parameter in the sending matrix of the CTS frame parsed by the AP is the same as the value of the second SCRAMBLER_INITIAL_VALUE parameter in the receiving matrix of the MU-RTS frame, it indicates that the STA does not have non-periodic communication services.

[0140] As shown in FIG4 , in some embodiments of the present disclosure, the method includes:

[0141] Step 401: The site device 101 determines a CTS frame, where the CTS frame includes newly added identification information.

[0142] The newly added identification information is a new identification information added to the CTS frame to identify whether the station device has a non-periodic communication service on other wireless communication media that needs to be transmitted. For example, the newly added identification information is set to a first parameter value, such as "0", to indicate that the STA does not have the aperiodic communication service; or the newly added identification information is set to a second parameter value, such as "1", to indicate that the STA has the aperiodic communication service.

[0143] Optionally, as shown in Figure 4, the newly added identification information can be carried in the frame control Frame Control field of the CTS frame. A new subfield is added to the Frame Control field to carry the newly added identification information; accordingly, the newly added identification information is set to "0", indicating that the STA does not have non-periodic communication services; the newly added identification information is set to "1", indicating that the STA has non-periodic communication services.

[0144] Step 402: The site device 101 sends the CTS frame.

[0145] In some embodiments, the STA sends a CTS frame, adds new identification information in the CTS frame, and uses the new identification information to identify whether the STA has a non-periodic communication service.

[0146] Step 403: The access point device 102 receives the CTS frame and parses the identification information of the CTS frame.

[0147] The AP receives the CTS frame and determines whether the STA has aperiodic communication service based on the newly added identification information in the CTS frame. For example, if the newly added identification information is "0", it indicates that the STA does not have aperiodic communication service; if the newly added identification information is "1", it indicates that the STA has aperiodic communication service.
