[0040] The embodiments of the present disclosure provide a parameter processing method, an access point device, a station device, and a communication system.

[0041] In a first aspect, an embodiment of the present disclosure provides a parameter processing method, the method comprising:

[0042] Determine a first radio frame, where the first radio frame includes first identification information, where the first identification information indicates that a BSS parameter of a basic service set (BSS) in which the AP is located has changed; wherein the BSS parameter includes: communication time information of a communication service of another wireless communication medium coexisting with the AP;

[0043] The first radio frame is sent.

[0044] In the above embodiment, the access point device transmits the first radio frame and broadcasts information about the BSS parameter change to STAs associated with it or STAs that are about to be associated with it, so that the STAs adjust their communication time with the access point device based on the BSS parameter change. For example, the STAs avoid uplink and downlink Wi-Fi communications with the access point device during the time when the access point device is transmitting communication services of other wireless communication media, or renegotiate Wi-Fi communication time with the access point device based on the time when communication services of other wireless communication media are transmitted. This avoids interference between Wi-Fi communication and communication services of other wireless communication media, isolates Wi-Fi communication services from services of other wireless communication media in terms of time, reduces interference with Wi-Fi communication caused by bursty communications of other wireless communication media, improves system throughput, and meets the transmission requirements of UHR.

[0045] In conjunction with some embodiments of the first aspect, in some embodiments, the first radio frame includes a TIM broadcast frame;

[0046] The first identification information includes a check beacon identification bit of the TIM broadcast frame; a change in the check beacon identification bit indicates a change in a BSS parameter of the BSS in which the AP is located;

[0047] The first identification information instructs the site device to receive and parse a first beacon frame following the TIM broadcast frame, where the first beacon frame carries parameter information after the BSS parameter is changed.

[0048] In the above embodiment, a change in the BSS parameters of the BSS in which the AP is located is indicated by the check beacon flag of the TIM broadcast frame. When the check beacon flag changes, the site device is instructed to receive and parse the first beacon frame following the TIM broadcast frame. The first beacon frame carries parameter information after the BSS parameters have changed, so that after determining the BSS parameter change of the BSS in which the AP is located based on the TIM broadcast frame, the site device receives the beacon frame sent by the AP and determines the parameter information after the BSS parameters have changed based on the beacon frame, thereby promptly obtaining the BSS parameter change information of the BSS in which the AP is located, thereby reducing the communication interference caused by communication tasks of other communication media on the current communication.

[0049] In conjunction with some embodiments of the first aspect, in some embodiments, after sending the first radio frame, the method further includes:

[0050] The first beacon frame is sent.

[0051] In the above embodiment, if the BSS parameters of the BSS where the AP is located change, a first beacon frame is sent after sending the TIM broadcast frame, so that the site device obtains the parameter information after the BSS parameter change according to the first beacon frame, and then negotiates the communication cycle with the AP based on the changed BSS parameter information to meet the UHR transmission requirements.

[0052] In conjunction with some embodiments of the first aspect, in some embodiments, the first radio frame includes at least one of a second beacon frame, an association response frame, and a reassociation response frame;

[0053] The first wireless frame includes the first identification information of the AP in the current working link and / or other links.

[0054] In the above embodiment, the AP may carry the first identification information during the process of establishing an initial association or reassociation with the STA. The first identification information identifies that the BSS parameters of the basic service set BSS in which the APP is located under the current working link and / or other links have changed, thereby avoiding communication interference caused by communication services of other wireless communication media coexisting with the AP to the current communication services, improving the system throughput, and making it suitable for the transmission requirements of UHR.

[0057] In the above embodiment, when the BSS parameters of the BSS in which the current working link is located change, the AP carries the changed parameter information in the link info field of the multi-link information element, so that the STA obtains the BSS parameter change information according to the link info field of the multi-link information element, and then negotiates the communication cycle with the AP based on the changed BSS parameter information to meet the UHR transmission requirements.

[0058] In combination with some embodiments of the first aspect, in some embodiments, the first identification information of the AP on the other link includes: a BSS Parameters Change Count Present flag;

[0065] In the above embodiment, the AP can use the STA Profile field of the per-STA profile sub-element of the multi-link information element of the first wireless frame to identify the parameter information of the BSS in which the BSS is located after the BSS parameter changes, so that the site device negotiates the communication cycle with the AP based on the changed BSS parameter information to meet the UHR transmission requirements.

[0122] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0123] As shown in FIG1 , a communication system 100 includes an access point (AP) 101 and a station (STA) 102 .

[0124] In some embodiments, the site device 102 includes, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal includes, but is not limited to, at least one of a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver capabilities, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device used in industrial control, a wireless terminal device used in self-driving, a wireless terminal device used in remote medical surgery, a wireless terminal device used in a smart grid, a wireless terminal device used in transportation safety, a wireless terminal device used in a smart city, and a wireless terminal device used in a smart home.

[0125] Specifically, the station device 102 may be a terminal device or network device with a Wireless Fidelity (WiFi) 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.

[0126] In some embodiments, the access point device 101 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.

[0127] 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.

[0128] 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.

[0129] 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.

[0130] 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.

[0131] FIG2 is an interactive diagram of a parameter processing method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0132] In step 201, the access point device 101 determines a first wireless frame, where the first wireless frame includes first identification information, where the first identification information indicates that a BSS parameter of the basic service set (BSS) in which the AP is located has changed; wherein the BSS parameters include: communication time information of communication services of other wireless communication media coexisting with the AP.

[0133] 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 one or more of Bluetooth (BT) technology, New Radio (NR) technology, Long Time Evolution (LTE) technology, Ultra Wide Band (UWB) technology, and Zigbee technology. When a device is performing WiFi communication, periodic or sudden communication tasks of other communication media will be generated, that is, there will be 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 latency, and being detrimental to the transmission of communication services. Therefore, in an embodiment of the present disclosure, a mechanism is provided to support the coexistence of WiFi wireless communication media and other communication media.

[0134] Specifically, the access point device 101 determines a first wireless frame, carries first identification information in the first wireless frame, and uses the first identification information to identify that the BSS parameters of the BSS in which the AP is located have changed; wherein the BSS parameters include: communication time information of communication services of other wireless communication media coexisting with the AP; communication services of other wireless communication media, such as one or more of the aforementioned BT technology, NR technology, LTE technology, UWB technology, and Zigbee technology.

[0135] It is understandable that, in some embodiments, the BSS parameters also include parameters other than the communication time information of the communication services of the other wireless communication media, which is not limited in the embodiments of the present disclosure.

[0136] The communication services of other wireless communication media that coexist with the AP, that is, the communication services of other wireless communication media within the BSS where the AP is located; for example, when the AP is a mobile AP, it may have communication with other communication devices using other wireless communication media, and the communication is the communication service of other wireless communication media within the BSS where the AP is located; or, the communication service of other wireless communication media within the BSS where the AP is located also includes the communication service of other wireless communication media of the site equipment within the BSS, which is not limited in the embodiments of the present disclosure.

[0137] Optionally, the change in BSS parameters includes a change in the communication time information of the communication service of the other wireless communication medium, such as the change in the communication time information, such as the lengthening or shortening of the period of the periodic communication service, or the change in the duration of the communication service.

[0138] In some embodiments, the first radio frame may be a Traffic Indication Map (TIM) broadcast frame, or may be at least one of a beacon frame, an association response frame, and a reassociation response frame.

[0139] Step 202: The access point device 101 sends the first wireless frame.

[0140] In some embodiments, the AP sends a TIM broadcast frame when there is a communication task of other wireless communication media coexisting with the AP.

[0141] The access point device 101 transmits the first radio frame and broadcasts information about the BSS parameter change to STAs associated with it or STAs that will be associated with it, so that the STAs adjust their communication time with the access point device 101 based on the BSS parameter change. For example, the STAs avoid uplink and downlink Wi-Fi communications with the access point device 101 during the time when the access point device 101 transmits communication services of other wireless communication media. Alternatively, the STAs renegotiate Wi-Fi communication time with the access point device 101 based on the time when the communication services of other wireless communication media are transmitted. This prevents interference between Wi-Fi communication and communication services of other wireless communication media, isolates Wi-Fi communication services from those of other wireless communication media in terms of time, reduces interference with Wi-Fi communication caused by bursty communications of other wireless communication media, and improves system throughput to meet UHR transmission requirements.

[0142] Step 203: The station device 102 receives the first radio frame.

[0143] After receiving the first wireless frame, the site device 102 avoids uplink and downlink Wi-Fi communications with the access point device 101 during the time when the access point device 101 transmits communication services of other wireless communication media, or renegotiates the communication time of Wi-Fi communication with the access point device 101 based on the time when the communication services of other wireless communication media are transmitted, thereby avoiding mutual interference between Wi-Fi communication and communication services of other wireless communication media.

[0144] In some embodiments of the present disclosure, after sending the first radio frame, the method further includes:

[0145] A request from a station device to renegotiate a Wi-Fi communication period is received.

[0146] Among them, when the device supports multi-link operation, the STA attached to the multi-link station device (Non-Access Point Multi-Link Device, Non-AP MLD) may have different listening periods for beacon frames or TIM frames under each link. The Non-AP MLD can wake up under one link to obtain information about multiple links. However, changes in link information may affect the Wi-Fi communication period (such as TWT SP, etc.) negotiated between the STA and the multi-link access point device (Access Point Multi-Link Device, AP MLD) or AP. In this case, the STA or Non-AP MLD needs to renegotiate the Wi-Fi communication period with the AP or AP MLD to avoid interference between Wi-Fi communication and communication services of other wireless communication media.

[0147] As shown in FIG3 , in some embodiments of the present disclosure, the method includes:

[0148] In step 301, the access point device 101 determines a TIM broadcast frame, where the TIM broadcast frame includes first identification information, where the first identification information indicates that a BSS parameter of a basic service set (BSS) in which the AP is located has changed; the first identification information includes a check beacon identification bit of the TIM broadcast frame; a change in the check beacon identification bit indicates that a BSS parameter of the BSS in which the AP is located has changed; the first identification information instructs the site device to receive and parse a first beacon frame following the TIM broadcast frame, where the first beacon frame carries parameter information after the BSS parameter change.

[0149] The BSS parameters include: communication time information of communication services of other wireless communication media coexisting with the AP.

[0150] In an embodiment of the present disclosure, if the STA supports the Traffic Indication Map (TIM) broadcast mechanism, during the initial association or reassociation between the STA and the AP, the radio frame sent in the aforementioned process carries a TIM broadcast request information element, indicating that the STA activates the TIM broadcast mechanism and negotiates with the AP for its listening period for TIM broadcast frames.

[0151] Optionally, the action field of the TIM broadcast frame is as shown in Table 1 below, including at least one of the following: a category field, an unprotected wireless network management action field, a beacon check field, a timestamp field, a TIM element, etc.

[0152] Table 1:

[0153] Among them, the Timestamp field is used to indicate the clock information, and the TIM element is used to inform the STA whether there is a downlink unicast or multicast service. The check beacon field is used to indicate whether the Basic Service Set (BSS) where the STA is located has a key BSS parameter update. For example, if the BSS where the AP is located has a BSS parameter update, the value of the check beacon field of the TIM broadcast frame is increased by 1. The initial value of the check beacon field is 0. Each time the STA receives a TIM broadcast frame, it records the value of the check beacon field. If the check beacon field of the most recently received TIM broadcast frame is different from the value of the check beacon field of the last received TIM broadcast frame, it indicates that the BSS where the AP is located has a BSS parameter update. The BSS parameters include but are not limited to the communication time information of the communication services of other wireless communication media that coexist with the AP.

[0154] In the disclosed embodiment, when there are communication tasks for other wireless communication media coexisting with the AP, the AP uses the check beacon field of the TIM broadcast frame to indicate changes in the BSS parameters of the basic service set (BSS) in which the AP is located. The BSS parameters include, but are not limited to, communication time information for the communication services of the other wireless communication media coexisting with the AP.

[0155] The first identification information instructs the site device to receive and parse the first beacon frame after the TIM broadcast frame, where the first beacon frame carries parameter information after the BSS parameter change. For example, when the value of the check beacon field changes, the STA is identified as needing to receive the first beacon frame after the TIM broadcast frame to receive and parse the parameter information after the BSS parameter change and determine communication information of other coexisting communication technologies.

[0156] Step 302: The access point device 101 sends the TIM broadcast frame.

[0157] In some embodiments, when there is a communication task of other wireless communication media coexisting with the AP, the AP sends a TIM broadcast frame to notify the STA that it needs to receive the first beacon frame after the TIM broadcast frame.

[0158] Step 303: The site device 102 receives the TIM broadcast frame.

[0159] In some embodiments, a STA receives a TIM broadcast frame sent by an AP during a period of listening to TIM broadcast frames and records the value of the Check Beacon field of the TIM broadcast frame. When there is a communication task on another wireless communication medium coexisting with the AP, the value of the Check Beacon field of the TIM broadcast frame is different from the value of the Check Beacon field of the last received TIM broadcast frame.

[0160] Step 304: The access point device 101 sends the first beacon frame.

[0161] In some embodiments, the AP sends a first beacon frame, such as a beacon frame, after sending the TIM broadcast frame, and the beacon frame carries parameter information after the BSS parameter is changed.

[0162] In step 305 , the site device 102 receives the first beacon frame, and receives and parses parameter information of the changed BSS parameters carried in the first beacon frame. For example, the BSS parameters carried in the first beacon frame are parameter information of the changed BSS parameters.

[0163] In some embodiments, the STA receives the TIM broadcast frame sent by the AP during the period of listening to the TIM broadcast frame, and records the value of the check beacon field of the TIM broadcast frame. When there is a communication task of other wireless communication media coexisting with the AP, the value of the check beacon field of the TIM broadcast frame is different from the value of the check beacon field of the TIM broadcast frame received last time. When the STA receives and parses the TIM broadcast frame and obtains a value that is different from the value of the check beacon field of the TIM broadcast frame received last time, the STA needs to receive the beacon frame sent by the AP after the TIM broadcast frame is sent, and obtain the parameter information after the BSS parameter change by parsing the beacon frame.

[0164] As shown in FIG4 , in some embodiments of the present disclosure, the method includes:

[0165] Step 401: determining a first radio frame, where the first radio frame includes at least one of a second beacon frame, an association response frame, and a reassociation response frame;

[0166] The first wireless frame includes first identification information, and the first identification information indicates that the BSS parameters of the basic service set BSS where the AP is located have changed; wherein the BSS parameters include: communication time information of communication services of other wireless communication media coexisting with the AP.

[0167] The first wireless frame includes the first identification information of the AP in the current working link and / or other links.

[0168] In some embodiments, if a STA is attached to a non-AP MLD and an AP is also attached to an AP MLD, the STA attached to the non-AP MLD may listen to at least one of beacon frames, association response frames, and reassociation response frames broadcast by the AP in any link that establishes a multi-link with the AP MLD.

[0169] For example, the AP carries parameter information of the changed BSS parameters of the AP in the current working link in the broadcast beacon frame, or the AP carries parameter information of the changed BSS parameters of the AP in other working links in the broadcast beacon frame.

[0170] In some embodiments, the first identification information of the AP on the current working link is carried in a multi-link control field of a multi-link information element of the first radio frame;

[0171] The parameter information of the AP after the BSS parameter of the current working link is changed is carried in the link info field of the multi-link information element.

[0172] As shown in Table 2 below, in the multi-link information element of the first radio frame, the multi-link control field includes at least one of an element identifier (Element ID), a length (Length), an element identifier extension (Element ID Extension), a multi-link control (Multi-Link Control), general information (Common info), and a connection information field (link info).

[0173] Table 2:

[0174] Among them, the AP identifies in the Multi-Link Control field of the multi-link information element of the broadcast beacon frame that the BSS parameter changes under the current working link, that is, the first identification information is carried in the multi-link control field; the parameter information after the BSS parameter changes is carried in the link info field.

[0175] In some embodiments, the first identification information of the AP on the other link includes: a BSS Parameters Change Count Present flag;

[0176] The BSS Parameters Change Count Present flag is set to the first parameter value, for example, the first parameter value is set to 1, indicating that the first identification information further includes: a BSS Parameters Change Count flag, where the BSS Parameters Change Count flag is used to carry indication information of whether the BSS parameters have changed;

[0177] The BSS Parameters Change Count flag bit changes, for example, the Count value changes, indicating that the BSS parameters of the BSS where the AP is located have changed;

[0178] 5 , the BSS Parameters Change Count Present identifier is carried in the STA control field of the per-STA profile sub-element of the multi-link information element;

[0179] The BSS Parameters Change Count Present flag is carried in the STA Info field of the per-STA profile sub-element.

[0180] Among them, the BSS parameter changes of the AP in other working links are carried in the per-STA profile sub-element of the multi-link information element, that is, the BSS parameter changes of the AP in other working links are carried as sub-elements of the multi-link information element in the per-STA profile sub-element.

[0181] As shown in Figure 5, the per-STA profile sub-element of the multi-link information element includes a per-STA profile sub-element identifier (Subelement ID), a length (Length), a STA control field (STA Control), a STA information field (STA info), and a STA Profile information field (STA Profile).

[0182] When the BSS parameters of the AP in other working links change, the BSS Parameters Change Count Present flag in the STA Control field of the per-STA profile domain is set to the first parameter value, and the BSS Parameters Change Count flag in the STA Info field of the per-STA profile domain is set to indicate that the BSS parameters of the BSS in which the AP is located have changed.

[0183] The STA Control field of the per-STA profile domain includes at least one of the following: link ID, complete profile, STA MAC Address Present, beacon interval Present, TSF Offset Present, DTIM Info Present, NSTR Link Pair Present, NSTR Bitmap Size, BSS Parameters Change Count Present, and reserved bit.

[0184] Among them, the STA info field of the per-STA profile domain includes at least one of STA information length (STA Info Length), STA physical address (STA MAC Address), beacon interval (Beacon Interva), TSF offset (TSF Offset), DTIM information (DTIM Present), NSTR indication byte (NSTR Indication Bitmap) and BSS parameter change (BSS Parameters Change Count).

[0185] For example, when the parameter value of the BSS Parameters Change Count Present flag is set to 1, the BSS Parameters Change Count flag in the STA info field of the per-STA profile domain indicates that the BSS parameters of the AP under other working links have changed. The parameter information after the specific BSS parameter change is carried in the STA Profile field of the per-STA profile sub-element shown in Figure 5.

[0186] Step 402: Send the first wireless frame.

[0187] In some embodiments, the AP sends a first wireless frame including at least one of a beacon frame, an association response frame, and a Re-association response frame.

[0188] Step 403: The site device 102 receives the first radio frame.

[0189] The station device 102 receives and parses parameter information after the BSS parameter change carried in the first radio frame, and avoids uplink and downlink Wi-Fi communications with the access point device 101 during the time when the access point device 101 transmits communication services of other wireless communication media. Alternatively, the station device 102 renegotiates the communication time of Wi-Fi communication with the access point device 101 based on the time when the communication services of other wireless communication media are transmitted, thereby avoiding mutual interference between Wi-Fi communication and communication services of other wireless communication media.

[0190] Optionally, in the process of the site device 102 receiving and parsing the first wireless frame, it first determines, based on the BSS Parameters Change Count Present flag, that the BSS Parameters Change Count flag exists in the STA control field of the per-STA profile sub-element; then, based on the BSS Parameters Change Count flag, it determines that when the BSS parameters of the BSS in which the AP is located change, it parses the STA Profile field of the per-STA profile sub-element to obtain the parameter information after the BSS parameters change.
