or

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 station device does not have the non-periodic communication service.

In the above embodiment, when 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, it indicates that the site device has a non-periodic communication service, which indicates that in the current scenario, the site device has a communication task of 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 indicates that the site device does not have the non-periodic communication service, which indicates that in the current scenario, the site device does not have a communication task of other communication media, so that 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 ability of the communication system.

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

As shown in Figure 1, the communication system 100 includes a station device (Station, STA) 101 and an access point device (Access Point, AP) 102.

In some embodiments, the site device 101 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi communication function. Optionally, the wireless communication terminal is, for example, a mobile phone, a wearable device, an Internet of Things device that supports Wi-Fi communication function, a car with Wi-Fi communication function, a smart car, a tablet computer (Pad), a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control (industrial control), a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in smart grid (smart grid), a wireless terminal device in transportation safety (transportation safety), a wireless terminal device in a smart city (smart city), and a wireless terminal device in a smart home (smart home), but is not limited thereto.

Specifically, the site device 101 may be a terminal device or a network device with a wireless fidelity (Wi-Fi) chip. Optionally, the site 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, 802.11bn, and support the next generation 802.11 protocol, but is not limited thereto.

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.

Optionally, in the disclosed embodiment, AP and STA may be devices supporting multiple connections, for example, may be respectively represented as a multi-connection access point device (Access Point Multi-Link Device, AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD); AP MLD may represent an access point supporting multi-connection communication functions, and non-AP MLD may represent a site supporting multi-connection communication functions.

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. A person of ordinary skill in the art 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.

The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 or part of the subject, but are not limited thereto. The subjects shown in FIG1 are examples. The communication system may include all or part of the subjects in FIG1, or may include other subjects other than FIG1. The number and form of the subjects are arbitrary. The subjects may be physical or virtual. The connection relationship between the subjects is an example. The subjects may be connected or disconnected. The connection may be in any manner, directly or indirectly. So a wired connection can also be a wireless connection.

The embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network using the 802.11 series of protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices with some association within a specific coverage area. One case of association is that stations communicate directly with each other in an ad hoc network, which is called an independent BSS (IBSS). Another more common case is that there is only one central station in the BSS network that is dedicated to managing the BSS, which is called an access point device, and all other STAs in the network are associated with it. Other stations in the BSS network that are not central stations are called terminals, also called non-AP STAs, and 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, etc., a STA cannot detect other STAs that are far away from it, and the two are hidden nodes of each other.

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

Step 201, the site device 101 determines a Clear To Send (CTS) frame, where the CTS frame identifies whether the site device 101 has non-periodic communication services on other wireless communication media.

In the WLAN (Wireless Local Area Network) communication scenario, in addition to supporting Wi-Fi wireless communication media, STA or AP may also support other wireless communication media, such as Bluetooth (Blue Tooth, BT) technology, New Radio (New Radio, NR) technology, Long Time Evolution (Long Time Evolution, LTE) technology, Ultra Wide Band (UWB) technology, Zigbee technology or one or more. When the device is performing Wi-Fi communication, it will generate periodic or non-periodic communication tasks of other communication media, that is, there is a situation where multiple communication media coexist at the same time, and multiple wireless communication media will generate co-frequency interference when communicating at the same frequency, thereby reducing the system throughput, increasing communication delay, and being unfavorable for transmitting communication services.

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.

Among them, STA determines the CTS frame, and the CTS frame identifies whether STA: has non-periodic communication services of other wireless communication media; specifically, there are non-periodic communication services of other wireless communication media, for example, after STA sends the CTS frame, there are other co-existing wireless communication technologies that need to send or receive non-periodic services; or there are non-periodic communication services of other wireless communication media, for example, other co-existing wireless communication technologies and Wi-Fi services have at least partial overlap in transmission time. Among them, the communication services of other wireless communication media are, for example, one or more of the aforementioned BT technology, NR technology, LTE technology, UWB technology, and Zigbee technology.

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

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 at the same time. The access point device can process the requests of multiple STAs by sending MU-RTS frames, and perform uplink or downlink communication with multiple STAs at the same time, thereby reducing contention on the channel and improving channel utilization.

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 means that the MU-RTS frame will be sent to all STAs in the network to ensure that all STAs can receive the MU-RTS frame, thereby coordinating data transmission between multiple devices.

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 disclosed embodiment, when responding to the MU-RTS frame, the STA uses the 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 STA has non-periodic communication services of other wireless communication media that need to be transmitted, and the AP still sends a multi-user physical layer control protocol data unit (Downlink Multi-User PLCP Protocol Data Unit, DL MU PPDU) frame or trigger frame to the STA, resulting in a waste of signaling resources, thereby reducing the system throughput, increasing communication delay, and being unfavorable for transmitting communication services.

In the embodiment of the present disclosure, when the AP determines through the CTS frame that a certain STA has non-periodic communication services of other wireless communication media that need to be transmitted, when sending a DL MU PPDU or trigger, it will no longer send to the STA, so as to avoid interference and conflict between the Wi-Fi communication services of the STA and the services of other wireless communication media.

Step 202: The station device 101 sends the CTS frame.

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.

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

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 of other wireless communication media that need to be transmitted.

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:

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 the STA.

Optionally, in some embodiments, if the AP learns from the CTS frame that the STA does not have any non-periodic communication services on other wireless communication media that need to be transmitted, then the AP sends a DL MU PPDU frame or a trigger frame to the STA; wherein the DL MU PPDU frame or the trigger frame includes the identification information of the STA, that is, the STA, as the receiving end of the DL MU PPDU frame or the trigger frame, performs uplink/downlink Wi-Fi communication normally. In addition, when the STA identifies through the CTS frame that there is no non-periodic communication service, the AP can adopt an optimization strategy that is more suitable for periodic communication.

In some embodiments of the present disclosure, the CTS frame identifies that the STA has the non-periodic communication service, and the method further includes:

The MU-RTS frame is received and sent again by the AP through EDCA.

Among them, 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 MU-RTS frames to the site equipment to realize 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.

If the STA has the non-periodic communication service, it receives the MU-RTS frame sent again by the AP in the channel obtained by competing again through EDCA, and realizes 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.

As shown in FIG. 3 , in some embodiments of the present disclosure, the method includes:

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.

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;

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.

In case 1, when the STA receives the MU-RTS frame, if the STA has non-periodic communication services on other communication media, the STA sets the value of the first SCRAMBLER_INITIAL_VALUE parameter in the transmission matrix of the CTS frame to be different from the value of the second SCRAMBLER_INITIAL_VALUE parameter; wherein the second SCRAMBLER_INITIAL_VALUE parameter is the parameter in the reception matrix of the MU-RTS frame it receives. In this way, when the AP receives the CTS frame, it can be determined that the STA has non-periodic communication services on other communication media that need to be transmitted based on the difference between the value of the first SCRAMBLER_INITIAL_VALUE parameter and the value of the second SCRAMBLER_INITIAL_VALUE parameter.

In case 2, if the STA does not have non-periodic communication services, the value of the first SCRAMBLER_INITIAL_VALUE parameter in the sending 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, according to the value of the first SCRAMBLER_INITIAL_VALUE parameter being the same as the value of the second SCRAMBLER_INITIAL_VALUE parameter, it can be determined that the STA does not have non-periodic communication services of other communication media that need to be transmitted, and then the uplink/downlink Wi-Fi communication with the STA can be performed normally.

Optionally, SCRAMBLER_INITIAL_VALUE refers to the initial value used to generate a pseudo-random sequence. During data transmission, a pseudo-random sequence is used to scramble data to enhance signal performance and security. By randomly scrambling data, correlation in the data transmission process can be reduced, interference can be reduced, and the signal's anti-interference ability can be improved.

Step 302: The station device 101 sends the CTS frame.

In some embodiments, the STA sends a CTS frame. If the STA has non-periodic communication services of other communication media that need to be transmitted, it is identified by the value of the SCRAMBLER_INITIAL_VALUE parameter in the sending matrix of the CTS frame, for example, the value of the SCRAMBLER_INITIAL_VALUE parameter in the sending matrix of the CTS frame is set to be different from the value of the SCRAMBLER_INITIAL_VALUE parameter in the receiving matrix of the MU-RTS frame.

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.

Among them, if the value of the first SCRAMBLER_INITIAL_VALUE parameter in the transmit matrix of the CTS frame parsed by the AP is different from the value of the second SCRAMBLER_INITIAL_VALUE parameter in the receive matrix of the MU-RTS frame, it indicates that the STA has a non-periodic communication service; if the value of the first SCRAMBLER_INITIAL_VALUE parameter in the transmit matrix of the CTS frame parsed by the AP is different from the value of the second SCRAMBLER_INITIAL_VALUE parameter in the receive matrix of the MU-RTS frame If the value of the second SCRAMBLER_INITIAL_VALUE parameter in the receiving matrix is the same, it indicates that the STA does not have a non-periodic communication service.

As shown in FIG. 4 , in some embodiments of the present disclosure, the method includes:

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

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

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.

Step 402: The station device 101 sends the CTS frame.

In some embodiments, the STA sends a CTS frame, adds new identification information in the CTS frame, and identifies whether the STA has a non-periodic communication service through the new identification information.

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

The AP receives the CTS frame and determines whether the STA has a non-periodic communication service based on the newly added identification information of the CTS frame. For example, when the newly added identification information is "0", it indicates that the STA does not have a non-periodic communication service; when the newly added identification information is "1", it indicates that the STA has a non-periodic communication service.
