[0049] This disclosure presents a QoS negotiation method, communication device, and communication system.

[0050] In a first aspect, embodiments of this disclosure propose a QoS negotiation method applied to a first site device (STA), the method comprising:

[0051] A first radio frame is determined; wherein the first radio frame includes first identification information, the first identification information identifying at least one of the following: a first latency requirement of a first communication link between a first STA and an access point device (AP), a second latency requirement of a second communication link between the AP and a second STA, and the total latency requirement of the first STA for the first communication link and the second communication link; wherein the second STA is a peer device that the first STA forwards communication with through the AP;

[0052] Send the first wireless frame.

[0053] In the above embodiments, the QoS negotiation process during data transmission is completed through negotiation between the AP and the communication peer, thereby meeting the latency requirements of the UHR service and improving communication performance.

[0054] In conjunction with some embodiments of the first aspect, in some embodiments, the first wireless frame further includes at least one of the following:

[0055] Transmitter ID (TID) information to identify the service transmitted between the first STA and the second STA;

[0056] The identification information of the communication peer device identifies the second STA and / or identifies the first radio frame as being used to negotiate communication latency requirements; the communication latency requirements include at least one of the first latency requirements, the second latency requirements, and the total latency requirements;

[0057] The second identification information is used to identify that the first wireless frame is used to negotiate the communication latency requirement;

[0058] Data communication time information includes the start time information of the first STA sending data to the AP, and / or the start time information of sending data under at least one third link between the multi-connection site device (non-AP MLD) to which the first STA is attached and the multi-connection access point device (AP MLD) to which the AP is attached.

[0059] In the above embodiments, the AP can accurately identify the type of service being transmitted between the first STA and the second STA using TID information, thereby conducting QoS negotiation to meet the transmission requirements of different services. Identifying the peer device ensures the bidirectional nature of the communication link and the identification of both communicating parties. Furthermore, the identification information of the peer device can be used to negotiate communication latency requirements, thereby optimizing and managing communication latency. This helps improve the real-time performance, stability, and efficiency of communication. By carrying the start time information of data communication in the first radio frame, the receiving end can more accurately understand the timing of data transmission, thus more effectively meeting the QoS requirements of different services.

[0060] In conjunction with some embodiments of the first aspect, in some embodiments, the method further includes:

[0061] The AP sends a second radio frame; wherein the second radio frame includes third identification information, which identifies the target communication link determined by the AP for transmitting downlink data with the second STA.

[0062] In the above embodiment, the second STA receives the third radio frame sent by the AP, establishes an SCS mechanism with the AP, and evaluates and decides whether to accept the content requested by the third radio frame based on the TID information carried in the third radio frame, the identification information of the second communication link, and the second delay requirement of the second communication link, thereby completing QoS negotiation.

[0063] In conjunction with some embodiments of the first aspect, in some embodiments, the method includes:

[0064] The target communication link includes the second communication link. Before the start time, the first STA receives a trigger frame sent by the AP and sends a data frame to the AP in response to the trigger frame.

[0065] or

[0066] The target communication link does not include the second communication link. The first STA sends a data frame to the AP, instructing the AP to forward the data frame to the second STA within the second latency requirement or the total latency requirement.

[0067] In the above embodiments, if the target communication link identified by the third identification information includes the second communication link, the first STA will receive a trigger frame sent by the AP before the start time of the data communication time information identification. This triggers the data transmission process, ensuring that the data can be transmitted to the second STA in a timely manner. If the target communication link does not include the second communication link, the first STA actively sends a data frame to the AP and instructs the AP to forward the data frame to the second STA within the second latency requirement or the total latency requirement. It should be noted that, on the one hand, if the AP forwards the data frame to the second STA within the second latency requirement, it can ensure that the target communication link meets the QoS requirements; on the other hand, if the AP forwards the data frame to the second STA within the total latency requirement, it needs to ensure that the latency already generated on the first communication link and the latency about to be generated on the target communication link do not exceed the total latency requirement.

[0089] or

[0091] In conjunction with some embodiments of the second aspect, in some embodiments, the method includes:

[0092] The target communication link includes the second communication link. Before the start time, the AP sends a trigger frame to the first STA and the second STA respectively, triggering the first STA to send a data frame to the AP and triggering the second STA to receive the data frame sent by the AP.

[0153] 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.

[0154] 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.

[0155] 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.

[0156] 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 APs 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.

[0157] Figure 2 is an interactive schematic diagram of a QoS negotiation method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0158] Step 201, the first STA 101 determines a first radio frame; wherein, the first radio frame includes first identification information, the first identification information identifying at least one of the following: a first latency requirement of a first communication link between the first STA 101 and AP 102, a second latency requirement of a second communication link between AP 102 and the second STA 103, and the total latency requirement of the first STA 101 for the first communication link and the second communication link; wherein, the second STA 103 is the peer device to which the first STA 101 forwards communication through AP 102.

[0159] Quality of Service (QoS) is a network management mechanism used to ensure that data transmitted in a network meets specific performance requirements. It involves multiple aspects, including bandwidth, latency, latency variation, jitter, and reliability. QoS provides different QoS guarantees for different types of data by setting priorities, allocating resources, managing traffic, and adjusting transmission strategies. Existing technologies effectively guarantee QoS latency requirements for uplink and downlink communication as well as peer-to-peer (P2P) communication in Wi-Fi networks by introducing the Reduced Target Wake Time (rTWT) mechanism. In uplink communication scenarios, devices can negotiate wake-up times with access points through the rTWT mechanism, transmitting data within specific time intervals to meet communication latency requirements. In downlink communication scenarios, access points negotiate wake-up times with devices through the rTWT mechanism, rationally scheduling data transmission timing to ensure data arrives at the target device in a timely manner, meeting communication latency requirements.

[0160] In device communication scenarios, the originating device has QoS requirements for the communication link, especially latency requirements. Excessive latency can lead to real-time communication interruptions, affecting real-time data processing. To address this issue, a new signaling process needs to be defined to optimize transmission latency in device communication scenarios, making it suitable for UHR requirements and ensuring the stability and reliability of real-time communication.

[0161] In this embodiment of the disclosure, a first site device (STA) determines a first radio frame. The first radio frame includes first identification information, which identifies at least one of the following: a first latency requirement for a first communication link between the first STA and an access point device (AP); a second latency requirement for a second communication link between the AP and a second STA; and the total latency requirement of the first STA for both the first and second communication links. The second STA is a peer device to which the first STA forwards communication via the AP. The first and second STAs may be non-AP STAs attached to a non-AP MLD, and the AP may be an AP attached to an AP MLD. The first latency requirement is the latency requirement for the first STA to transmit uplink data on the first communication link with the AP; the second latency requirement is the latency requirement for the AP to transmit downlink data on the second communication link with the second STA. The second STA is another device to which the first STA is communicating. The first radio frame may be, for example, a stream classification service request (SCS Request) frame.

[0162] In some embodiments, the first radio frame carries the total latency requirements of the first STA for the first communication link and the second communication link, the total latency requirements including a first latency requirement and a second latency requirement.

[0163] Specifically, in device communication scenarios, if data transmission is performed directly without specifying the transmission latency of the communication link, the latency may not be effectively managed and adjusted, leading to excessively long or unstable communication latency, which in turn affects the real-time performance and reliability of the communication. Secondly, due to the lack of QoS adjustment and optimization, the bandwidth utilization of the communication link may decrease, resulting in insufficient resource utilization.

[0164] In this embodiment, a first STA sends a first radio frame to its associated AP. The first radio frame includes first identification information, which identifies at least one of the following: a first latency requirement of a first communication link between the first STA and the access point device (AP); a second latency requirement of a second communication link between the AP and a second STA; and the total latency requirement of the first STA for both the first and second communication links. By sending the first radio frame, the AP negotiates with its communication peer to complete the QoS negotiation process during data transmission, thus meeting the latency requirements of the UHR service. This method avoids excessively long or unstable latency during data transmission, thereby improving the real-time performance and reliability of communication.

[0165] Specifically, the first STA identifies the latency requirements of the first communication link with the AP, enabling the AP to adjust transmission timing and parameters accordingly to meet the first STA's needs. The first STA also identifies the latency requirements of the second communication link between the AP and the second STA, allowing the AP to consider the communication needs of both the first and second STAs during data transmission. This allows the AP to rationally adjust its communication strategy based on the latency requirements provided by the first STA during QoS negotiation, effectively improving the quality and reliability of the communication links. By identifying the total latency requirements of both the first and second communication links, the first STA can comprehensively consider the latency requirements of both its communication links with the AP and between the AP and the second STA, coordinating the transmission timing and parameter settings of both links to maximize overall communication link performance. This effectively avoids excessively long or unstable communication delays, improving real-time performance and reliability. Furthermore, by comprehensively considering the overall latency requirements, the bandwidth utilization and resource efficiency of the communication links can be further optimized, enhancing the overall performance of the communication system.

[0166] Step 202: The first STA 101 sends the first radio frame.

[0167] In this embodiment of the disclosure, the first STA sends a first radio frame to the associated AP. Wherein, if the first STA is attached to a non-AP MLD and the AP is attached to an AP MLD, the first STA can send the first radio frame over one or more links between the non-AP MLD and the AP MLD.

[0168] In some embodiments, the first wireless frame further includes at least one of the following: Transmission Identifier (TID) information, identification information of the communication peer device, second identification information, and data communication time information.

[0169] The TID information identifies the service being transmitted between the first STA and the second STA. Through the TID information, the AP can accurately identify the type of service being transmitted between the first STA and the second STA, and then perform QoS negotiation to meet the transmission requirements of different services.

[0170] The identification information of the communication peer device identifies the second STA and / or indicates that the first radio frame is used to negotiate communication latency requirements. The communication latency requirements include at least one of the first latency requirement, the second latency requirement, and the total latency requirement. For example, the identification information of the communication peer device can identify at least one of the second STA's Media Access Control (MAC) address, Association Identifier (AID), and the first radio frame used to negotiate communication latency requirements. Identifying the communication peer device ensures the bidirectional nature of the communication link and the identification of both communicating parties. Furthermore, the identification information of the communication peer device can be used to negotiate communication latency requirements, thereby optimizing and managing communication latency. This helps improve the real-time performance, stability, and efficiency of communication.

[0171] The second identification information is used to identify that the first radio frame is used to negotiate the communication latency requirement. The communication latency requirement includes at least one of the first latency requirement, the second latency requirement, and the total latency requirement. The identification information of the communication peer device can be used to negotiate the communication latency requirement, thereby optimizing and managing the communication latency. This helps improve the real-time performance, stability, and efficiency of communication.

[0172] The data communication timing information includes the start time information of the first STA sending data to the AP, and / or the start time information of data transmission under at least one third link between the multi-connection site device (non-AP MLD) to which the first STA is attached and the multi-connection access point device (AP MLD) to which the AP is attached. For example, the data communication timing information includes the start time information of the first STA sending UL data frames to the AP. If the first STA and the AP support multi-link operation, the data communication timing information identifies the start time information of the first STA sending UL data frames to the AP on a specific link. If the first STA and the second STA are attached to the non-AP MLD, and the AP is attached to the AP MLD, and the first STA and the second STA have established a Transmission Identifier to Link (TID-To-link) mechanism with the AP, the data communication timing information also includes the start time information of data transmission under at least one third link between the non-AP MLD and the AP MLD. By carrying the start time information of data communication in the first radio frame, the embodiments of this disclosure enable the receiving end to more accurately understand the timing of data transmission, thereby more effectively meeting the QoS requirements of different services.

[0173] Step 203, AP 102 receives a first radio frame; wherein the first radio frame includes first identification information, the first identification information identifying at least one of the following: a first latency requirement of a first communication link between a first STA 10 and AP 102, a second latency requirement of a second communication link between AP 102 and a second STA 103, and the total latency requirement of the first STA 101 for the first communication link and the second communication link; wherein the second STA 103 is the peer device to which the first STA 101 forwards communication through AP 102.

[0174] In this embodiment of the disclosure, the AP receives a first wireless frame, which includes at least one of the following: the latency requirement of the first communication link between the first STA and the AP, the latency requirement of the second communication link between the AP and the second STA, and the total latency requirement of the first ST for the first communication link and the second communication link.

[0175] Step 204, AP 102 determines the third radio frame; wherein the third radio frame includes the TID information, the identification information of the second communication link, and the second latency requirement.

[0176] In this embodiment, after receiving the first radio frame, the AP establishes a Stream Classification Service (SCS) mechanism with the second STA. The SCS mechanism is primarily used to classify and manage network data flows to optimize traffic and manage QoS. By establishing the SCS mechanism with the second STA, the AP can negotiate QoS requirements, including data transmission delay agreements and link selection, to ensure the effectiveness and stability of data transmission. Specifically, the AP determines a third radio frame, which includes the TID information, the identification information of the second communication link, and the second delay requirement.

[0177] Step 205, AP 102 sends the third radio frame to the second STA 103.

[0178] In this embodiment, the AP sends the third radio frame to the second STA. The third radio frame includes the TID information, the identification information of the second communication link, and the second latency requirement. The second STA can use this information to evaluate and decide whether to accept the content requested by the third radio frame, thereby completing QoS negotiation. Specifically, the second STA can evaluate whether the latency requirement of the second communication link meets its requirements and whether there are sufficient resources to support the requested content, based on its own communication needs and current network conditions. If the second STA decides to accept the content requested by the third radio frame, it can prepare to receive data frames forwarded by the first STA through the AP and perform data reception and processing according to the negotiated QoS policy and latency requirement to meet specific service requirements. If the second STA rejects the content requested by the third radio frame, the second STA can provide the AP with information about other available links to help the AP select a more suitable link as the target communication link with the second STA, thereby meeting the communication latency requirement of the first STA.

[0179] Step 206: The second STA 103 receives the third radio frame sent by the AP 102; the third radio frame includes: TID information of the service transmitted between the first STA 101 and the second STA 102, identification information of the second communication link between the first STA 101 and the second STA 102, and the second latency requirement of the second communication link.

[0180] In this embodiment of the present disclosure, the second STA receives the third radio frame sent by the AP, establishes an SCS mechanism with the AP, and evaluates and decides whether to accept the content requested by the third radio frame based on the TID information carried by the third radio frame, the identification information of the second communication link, and the second delay requirement of the second communication link, thereby completing QoS negotiation.

[0181] Step 207, the second STA 103 determines the fourth radio frame; wherein the fourth radio frame indicates whether the second STA 103 accepts the content requested by the third radio frame.

[0182] In this embodiment of the disclosure, the second STA determines a fourth radio frame, which indicates whether the second STA accepts the content requested by the third radio frame. For example, whether the second STA accepts receiving downlink data frames transmitted by the AP on the second communication link, and whether the second communication link has a second latency requirement.

[0183] In some embodiments, if the fourth radio frame indicates that the second STA accepts the content requested by the third radio frame, then the link for downlink communication between the AP and the second STA is the second communication link;

[0184] or

[0185] If the fourth radio frame indicates that the second STA rejects the content requested by the third radio frame, then the downlink communication link between the AP and the second STA is another communication link.

[0186] Specifically, the fourth radio frame indicates that the second STA has accepted the content requested by the third radio frame. This means that the second STA has agreed to establish communication with the AP and is ready to receive data frames from the first STA. In this case, the downlink link between the AP and the second STA will be the second communication link. If the fourth radio frame indicates that the second STA has rejected the content requested by the third radio frame, the AP can choose another communication link for downlink communication, or select another communication link for downlink communication based on information about other available links provided by the second STA, to ensure smooth data transmission. This flexibility allows the communication system to better adapt to different network conditions and device states, thereby improving the reliability and stability of communication.

[0187] Step 208: The second STA 103 sends a fourth radio frame to the AP 102.

[0188] In this embodiment of the disclosure, the second STA sends a fourth radio frame to the AP. The fourth radio frame indicates whether the second STA accepts the content requested by the third radio frame. This helps to achieve real-time QoS feedback and communication flexibility, while optimizing resource utilization and improving the reliability and efficiency of communication.

[0189] Step 209: AP 102 receives a fourth radio frame sent by the second STA 103, wherein the fourth radio frame indicates whether the second STA 103 accepts the content requested by the third radio frame.

[0190] In this embodiment of the disclosure, the AP receives a fourth radio frame. If the fourth radio frame indicates that the second STA accepts the content requested by the third radio frame, the AP determines to conduct downlink communication with the second STA on the second communication link. If the fourth radio frame indicates that the second STA rejects the content requested by the third radio frame, the AP can choose another communication link for downlink communication, or select another communication link for downlink communication based on information about other available links provided by the second STA, to ensure smooth data transmission.

[0191] Step 210, AP 102 determines a second radio frame; wherein the second radio frame includes third identification information, the third identification information identifying the target communication link determined by AP 102 for transmitting downlink data with the second STA 103.

[0192] In this embodiment of the disclosure, after receiving the fourth radio frame, the AP determines the second radio frame based on the information identified by the fourth radio frame. The third identification information identifies the target communication link determined by the AP for transmitting downlink data with the second STA. For example, if the fourth radio frame indicates that the second STA accepts the content requested by the third radio frame, the AP determines the second communication link as the target communication link, meaning the AP performs downlink communication with the second STA on the second communication link. If the fourth radio frame indicates that the second STA rejects the content requested by the third radio frame, the AP can choose another communication link as the target communication link, or select another communication link as the target communication link based on information about other available links provided by the second STA.

[0193] Step 211, AP 102 sends the second radio frame to the first STA 101.

[0194] In this embodiment of the disclosure, the AP replies with a second radio frame to the first STA based on the QoS negotiation with the second STA, enabling the first STA to more effectively understand the downlink data transmission path and the target communication link. The second radio frame includes a stream classification service request (SCS response) frame.

[0195] Step 212: The first STA 101 receives the second radio frame sent by the AP 102; wherein the second radio frame includes third identification information, the third identification information identifying the target communication link determined by the AP 102 for transmitting downlink data with the second STA 103.

[0196] In this embodiment of the present disclosure, the first STA receives the second radio frame sent by the AP, and determines whether data transmission can be performed according to the predetermined timing arrangement based on the third identification information carried in the second radio frame, thereby ensuring the timeliness and reliability of communication.

[0197] As an example, referring to Figure 3, Figure 3 illustrates an optional implementation of an embodiment of this disclosure, including the following steps:

[0198] Step 301: The target communication link includes the second communication link, and the first STA 101 receives the trigger frame sent by the AP 102 before the start time.

[0199] In this embodiment of the disclosure, if the target communication link identified by the third identification information includes the second communication link, the first STA will receive a trigger frame sent by the AP before the start time of the data communication time information, which triggers the data transmission process.

[0200] Step 302: The first STA 101 sends a data frame to the AP 102.

[0201] In this embodiment of the disclosure, the first STA will send a UL data frame to the AP after responding to the received trigger frame, ensuring that the data can be transmitted to the second STA in a timely manner. In this case, the first STA can transmit data according to a predetermined timing schedule, ensuring the timeliness and reliability of communication.

[0202] Step 303: AP 102 receives the data frame and forwards the data frame to the second STA 103.

[0203] In this embodiment of the disclosure, after receiving a data frame, the AP forwards the data frame to the second STA within the second latency requirement, or forwards the data frame to the second STA within the total latency requirement, thereby ensuring that the target communication link meets the QoS requirements.

[0204] As an example, referring to Figure 4, Figure 4 illustrates another optional implementation of the embodiments of this disclosure, including the following steps:

[0205] Step 401, the target communication link does not include the second communication link, the first STA 101 sends a data frame to the AP 102, instructing the AP 102 to forward the data frame to the second STA 103 within the second latency requirement or the total latency requirement.

[0206] In this embodiment, if the target communication link does not include the second communication link, the first STA actively sends a data frame to the AP and instructs the AP to forward the data frame to the second STA within the second latency requirement or the total latency requirement. It should be noted that, on the one hand, if the AP forwards the data frame to the second STA within the second latency requirement, it can ensure that the target communication link meets the QoS requirements; on the other hand, if the AP forwards the data frame to the second STA within the total latency requirement, it needs to ensure that the latency already generated on the first communication link and the latency about to be generated on the target communication link do not exceed the total latency requirement, that is, the AP forwards the data frame to the second STA within the total latency requirement (time). Furthermore, if in a certain communication scenario, the latency generated on the first communication link is t1, the total latency requirement is t0, and the second latency requirement is t2; if the remaining time t3 after subtracting t1 from t0 is greater than t2, then the latency of the second communication link can be t3, satisfying that the actual latency generated on both links does not exceed the total latency requirement.

[0207] Step 402: AP102 receives the data frame and forwards it to the second STA103 within the second delay requirement or the total delay requirement.

[0208] In this embodiment, after receiving a data frame, the AP transmits the data frame to the second STA via the target chain within the second latency requirement or the total latency requirement. The first STA, by explicitly instructing the AP's actions, effectively controls the timing and process of data transmission, and better meets the latency requirements of unidirectional data transmission from the sender to the receiver. Such proactive control improves the reliability and stability of communication, ensures high-quality data transmission in the network, and is suitable for UHR requirements.

[0209] In some embodiments, if the target communication link does not include a second communication link, the first STA actively initiates data transmission and instructs the AP to forward the data frame to the second STA. In this case, since the data transmission is forwarded through the AP, it is necessary to consider the clock (Timing Synchronization Function, TSF) offset values ​​between the AP and the first STA, as well as between the AP and the second STA, to ensure clock synchronization of these devices and guarantee reliable data transmission. Therefore, it is necessary to consider the TSF offset values ​​under the first link and the target link to adjust the transmission clock, maintain time synchronization between the devices, and thus achieve the accuracy and stability of data transmission.

[0210] For example, the AP broadcasts time synchronization messages to both the first and second STAs, containing the current TSF value. Upon receiving these messages, the first and second STAs adjust their local clocks according to the received TSF value to maintain synchronization with the AP. Then, the first STA sends a UL data frame to the AP, instructing the AP to forward the data frame to the second STA within the second latency requirement or the total latency requirement. During this process, the AP adjusts its transmission clock according to the latency requirement indicated by the first STA, ensuring that data is transmitted to the second STA within the specified latency range. Simultaneously, the AP may also periodically send time synchronization messages to both the first and second STAs to maintain time synchronization between the devices. If clock drift or desynchronization occurs during communication, the devices can calibrate using the received time synchronization messages to ensure consistent TSF values.
