[0053] The following will describe the technical solutions in the embodiments of this application in conjunction with the drawings in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of the embodiments. With respect to the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0054] The technical solutions of the embodiments of the present application can be applied to various communication systems, such as Wireless Local Area Networks (WLAN), Wireless Fidelity (WiFi), or other communication systems.

[0055] Please refer to Figure 1, which shows a schematic diagram of a wireless communication system provided by an embodiment of the present application. As shown in Figure 1, the wireless communication system may include: an access point (AP) and a station (STA).

[0056] In some scenarios, an AP can be referred to as an AP STA, meaning that in a sense, an AP is also a type of STA. In some scenarios, a STA can be referred to as a non-AP STA.

[0057] In some embodiments, STAs may include AP STAs and non-AP STAs. Communication in a communication system may be between an AP and a non-AP STA, between a non-AP STA and a non-AP STA, or between a STA and a peer STA. A peer STA may refer to a device that communicates with a STA. For example, a peer STA may be an AP or a non-AP STA.

[0058] An AP acts as a bridge between wired and wireless networks, connecting wireless network clients together and then connecting the wireless network to the Ethernet. An AP can be a terminal device (such as a mobile phone) or a network device (such as a router) equipped with a Wireless Fidelity (Wi-Fi) chip.

[0059] It should be understood that the role of STA in the communication system is not absolute. For example, in some scenarios, when a mobile phone is connected to a router, the mobile phone is a Non-AP STA. When the mobile phone serves as a hotspot for other mobile phones, the mobile phone acts as an AP.

[0060] APs and non-AP STAs can be devices used in the Internet of Vehicles, IoT nodes and sensors in the Internet of Things (IoT), smart cameras, smart remote controls, smart water and electricity meters in smart homes, and sensors in smart cities.

[0061] In some embodiments, a non-AP STA may support 802.11be. A non-AP STA may also support various current and future 802.11 family wireless LAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0062] In some embodiments, the AP may be a device supporting the 802.11be standard. The AP may also be a device supporting various current and future 802.11 family WLAN standards, such as 802.11ax, 802.11ac, 802.11n, 802.11g, 802.11b, and 802.11a.

[0065] There are one or more links between the station and the access point. In some embodiments, the station and the access point support multi-band communication. For example, communication is performed simultaneously on the 2.4 GHz, 5 GHz, 6 GHz, 45 GHz, and 60 GHz frequency bands, or communication is performed simultaneously on different channels of the same frequency band (or different frequency bands), thereby improving the communication throughput and / or reliability between devices. Such a device is generally referred to as a multi-band device, or a multi-link device (MLD), sometimes also referred to as a multi-link entity or a multi-band entity. A multi-link device can be an access point device or a station device. If the multi-link device is an access point device, the multi-link device includes one or more APs; if the multi-link device is a station device, the multi-link device includes one or more non-AP STAs.

[0066] A multi-link device including one or more APs may be referred to as an Access Point Multi-Link Device (AP MLD), and a multi-link device including one or more non-AP STAs may be referred to as a Non-AP Multi-Link Device (Non-AP MLD).

[0067] In an embodiment of the present application, the AP may include multiple APs, the Non-AP may include multiple STAs, multiple links may be formed between the APs in the AP and the STAs in the Non-AP, and data communication may be performed between the APs in the AP and the corresponding STAs in the Non-AP through the corresponding links.

[0077] In the embodiments of the present application, the “protocol” may refer to a standard protocol in the communication field, for example, it may include a WiFi protocol and related protocols used in future WiFi communication systems, and the present application does not limit this.

[0078] To facilitate a better understanding of the embodiments of the present application, the predictable delay related to the present application is explained.

[0079] Traffic flows originating from many real-time applications have strict requirements on delay and jitter as well as certain reliability constraints. Such traffic is called delay-sensitive traffic. Delay-sensitive traffic requires that data packets be delivered on a wireless link with predictable delays in terms of both average and worst-case delays. Such traffic typically exhibits a periodic pattern of bursty arrivals of data in each interval. Mechanisms such as stream classification service (SCS) and restricted target wake time (R-TWT) enable the Basic Service Set (BSS) to use enhanced medium access protection and resource reservation to provide predictable delays with higher reliability for delay-sensitive traffic on wireless links.

[0080] To facilitate a better understanding of the embodiments of the present application, the QoS feature elements related to the present application are explained.

[0081] The QoS Characteristics element contains a set of parameters that define the characteristics and QoS expectations of the service flow for a specific non-AP Extremely High Throughput Station (Non-AP EHT STA). It is used by EHT APs and Non-AP EHT STAs to use the SCS mechanism with R-TWT to support QoS service flow transmission.

[0082] For example, the format definition of the QoS feature element is shown in Figure 2. The Delay Bound field contains an unsigned integer that specifies the maximum amount of time (in microseconds) allowed for the transmission of a Media Access Control Service Data Unit (MSDU) or Aggregate Media Access Control Service Data Unit (A-MSDU) belonging to the service flow described by the element. This maximum amount of time is measured from the time the first MSDU of the MSDU or MSDU constituting an A-MSDU arrives at the local Media Access Control (MAC) sublayer at the local MAC Secondary Access Point (SAP) to the time the MSDU or A-MSDU is successfully transmitted or retransmitted to the destination. The completion time of the MSDU or A-MSDU transmission includes the corresponding acknowledgment frame transmission time.

[0083] The MSDU Transmission Ratio subfield specifies the MSDU loss requirement and is encoded as defined in the MSDU Transmission Ratio subfield value shown in Table 1.

[0084] Table 1

[0085] The MSDU Count Index subfield contains an unsigned integer that specifies the index of the number of incoming MSDUs used to calculate the MSDU transmission ratio.

[0086] To facilitate a better understanding of the embodiments of the present application, the EHT SCS mechanism related to the present application is described.

[0087] The Non-AP MLD uses the SCS mechanism to request the AP MLD to classify the incoming individually addressed MSDUs based on the parameters provided by the Non-AP MLD and / or describe their service characteristics to the AP MLD.

[0088] A non-AP EHT STA may send an SCS request frame with an SCS descriptor element containing a QoS Characteristics element, wherein the request type field in the frame is set to "add" or "change." The QoS Characteristics element describes the service characteristics of the requested SCS flow.

[0089] MLD maintains the SCS identity (SCS ID) at the MLD level. That is, in the SCS request frame sent to the AP attached to the AP MLD, the SCS ID used by the Non-AP STA attached to the Non-AP MLD is unique among all STAs attached to the Non-AP MLD.

[0090] If an SCS request frame with an SCS description element containing a QoS characteristics element is rejected by the EHT AP by setting the status field value to REJECTED_WITH_SUGGESTED_CHANGES, the AP shall include an SCS descriptor element containing a QoS characteristics element in an SCS response frame to signal the recommended QoS characteristics parameters for that SCS flow. The AP shall include an SCS descriptor element containing a QoS characteristics element in an SCS response frame with the status field value set to SUCCESS or REJECTED_with_SUGESTED_CHANGES only if the SCS descriptor element in the corresponding SCS request frame contains a QoS characteristics element.

[0091] The following fields in the QoS Features element in the corresponding SCS Descriptor element included in the SCS Response frame may be different from the corresponding values ​​in the requested SCS flow: Minimum Service Interval, Maximum Service Interval, Service Start Time, and Medium Time.

[0092] The QoS Characteristics element is a reference for scheduling by the EHT AP. If the Direction subfield of the QoS Characteristics element indicates downlink, the EHT AP shall schedule the transmission of downlink frames so that the requested delay bound and minimum data rate are met for downlink data frames. The EHT AP shall enable the transmission of uplink frames from the EHT STA at intervals between the requested minimum and maximum serving intervals, and if the Direction subfield of the QoS Characteristics element indicates uplink, the AP shall meet the requested minimum data rate. The EHT AP shall enable the transmission of direct link frames from the EHT STA to another STA at intervals between the requested minimum and maximum serving intervals on the link specified in the Link Identification (LinkID) subfield of the Control Information field.

[0093] If the EHT STA is a target wake time (TWT) scheduling STA or a TWT requesting STA, and there is a negotiated TWT service period (SP) for the traffic identifier (TID) specified in the QoS feature element with the EHT AP, the EHT AP shall ensure that the service interval is consistent with the negotiated TWT wake-up interval.

[0094] If the EHT STA is an R-TWT scheduled STA and there is a negotiated R-TWT SP for the TID specified in the QoS Features element. If the negotiated R-TWT SP for the TID specified in the QoS Features element is trigger-enabled R-TWT, the EHT AP shall ensure that the trigger frame is scheduled at the beginning of the R-TWT SP.

[0095] In order to facilitate a better understanding of the embodiments of the present application, the R-TWT related to the present application is explained.

[0096] The Target Wake Time (TWT) wake-up mechanism first appeared in the IEEE 802.11ah "Wi-Fi HaLow" standard to support energy conservation in large-scale IoT environments. In IEEE 802.11ax, the TWT mechanism builds on IEEE 802.11ah by adding support for triggered uplink transmissions, thereby expanding the scope of TWT operation.

[0097] In TWT, a schedule is established between the STA and the AP (this schedule is agreed upon by the STA and AP). The schedule is composed of TWT time periods. When the negotiated time period expires, the STA wakes up, waits for the trigger frame sent by the AP, and performs a data exchange. After the transmission is complete, the STA returns to sleep. Each STA can independently negotiate with the AP and has a unique TWT time period.

[0098] TWT allows the AP to manage the behavior of the basic service set (BSS) to alleviate contention between stations and reduce the awake time of stations in power management mode. This is achieved by stations operating in non-overlapping time and / or frequency domains and concentrating frame exchanges in predefined service periods. Therefore, to ensure the effectiveness of TWT, the AP generally requires that all associated stations in the BSS can join the TWT so that the AP can schedule them. According to the TWT protocol of IEEE 802.11ax, high-efficiency (HE) APs (specifically IEEE 802.11ax) will request all associated stations that claim to support TWT to participate in TWT. Non-AP stations (non-AP STAs) should perform individual customized TWT (individual TWT) protocol negotiation or join the broadcast TWT (broadcast TWT) after receiving the AP's indication to join TWT. In addition, the service period (SP) of TWT includes trigger-enabled SPs and non-trigger-enabled SPs. The TWT scheduling AP schedules by sending trigger frames in the trigger-enabled SP. At the same time, IEEE802.11ax stipulates that TWT scheduled sites cannot transmit frames to TWT scheduling APs outside the broadcast TWT SP. Moreover, in trigger-enabled broadcast TWT, TWT scheduled sites cannot transmit frames that do not carry HE triggered physical layer protocol data units (PPDU) (HE TB PPDU) to TWT scheduling APs.

[0099] The currently defined R-TWT is based on broadcast TWT. In the broadcast TWT operation, the TWT scheduling AP carries a broadcast TWT element in the broadcast beacon frame to indicate the broadcast TWT service period (broadcast TWT SP). In the trigger-enabled service period, after competing for the channel access opportunity, the AP transmits a trigger frame or a downlink buffer unit (BU) to the TWT scheduled station (TWT scheduled STA). For example, after STA1 and STA2 complete the frame exchange with the AP in the TWT SP, they enter the sleep state outside the TWT SP.

[0100] IEEE 802.11be proposes restricted TWT operations to allow APs to utilize enhanced medium access protection and resource reservation mechanisms to provide more predictable, lower worst-case latency and jitter, and higher reliability for the transmission of low-latency services. Currently, Restricted TWT mainly adds two channel access rules in terms of channel access: extremely high throughput (EHT) non-AP stations (non-AP STAs) as transmission opportunity (TXOP) owners, when the TXOP is obtained outside the restricted TWT service period, should ensure that their TXOP ends before the start of any restricted TWT service period; EHT APs will schedule quiet intervals that overlap with the restricted TWT service period to shield legacy STAs that support the Quiet Element from operating within the TWT SP, but the shielding operation within the quiet time interval is invalid for non-AP EHT STAs.

[0101] To facilitate a better understanding of the embodiments of the present application, the BSS load elements related to the present application are described.

[0102] The BSS Load element contains information about the current number of STAs in the BSS and the traffic level. The element information format is shown in Figure 3 (BSS Load Unit Format). When performing a BSS transition, STAs can use this element for vendor-specific AP selection algorithms.

[0103] The Channel Utilization field is defined as the percentage of time that the AP senses that the medium is busy, using a linear scale of 255 (255 represents 100%), where medium busyness is indicated by a physical or virtual carrier sensing (CS) mechanism.

[0104] The Available Admission Capacity field contains an unsigned integer that specifies the remaining amount of medium time available through explicit admission control, in units of 32 μs / s. This field helps BSS transitions select APs that may accept future admission control requests, but it does not represent a guarantee that the hybrid coordinator (HC) will admit these requests.

[0105] To facilitate understanding of the technical solutions of the embodiments of the present application, the problems solved by the present application are described below.

[0106] Although the Restricted TWT operation provides a mechanism for prioritizing the transmission of delay-sensitive service flows using pre-scheduled service cycles, the application effect of the Restricted TWT operation for enhancing the transmission of delay-sensitive service flows is limited by factors such as the transmission performed by the associated EHT STA that does not support R-TWT and / or the legacy station (pre-EHT STA) that does not support the quiet interval (quiet interval) corresponding to the BSS of the Restricted TWT operation, as well as the overlapping basic service sets (OBSS).

[0107] In addition, although the current BSS load element provides the current BSS load situation by including information about the current number of STAs and traffic size levels in the BSS and the available access capacity, it cannot reflect the resources available for transmission of delay-sensitive service flows based on AP scheduling capabilities, which is not conducive to the STA that intends to transmit delay-sensitive service flows to select the associated AP or link and specific R-TWT and establish SCS.

[0108] As shown in Figure 4, in measurement period a and measurement period b, for the parameters of the BSS load element, although the value of the Available Admission Capacity field is the same, there are significant differences in their available service time QoS parameters (such as available service cycle duration, available service time interval, etc.), so the degree of support for delay-sensitive services is different.

[0109] Based on the above problems, the present application proposes an evaluation mechanism for QoS parameters of delay-sensitive service flow transmission based on AP scheduling capabilities. By providing evaluation information of delay-sensitive service flow transmission QoS parameters based on AP scheduling capabilities, as well as recommended transmission flow characteristic parameters, recommended site or link operations and capabilities to achieve the evaluated delay-sensitive service flow transmission QoS parameters, the recommended site or link transceiver capability parameter information can enable the site receiving the information to use the information it conveys, firstly, to select the AP or link to be used for low-latency service flow transmission in the implementation-specific AP or link selection algorithm; secondly, for a specific AP or link, to select the R-TWT corresponding to the specific restricted TWT schedule (R-TWT schedule) that the AP or link has established and intends to join.

[0110] To facilitate understanding of the technical solutions of the embodiments of the present application, the technical solutions of the present application are described in detail below through specific embodiments. The following related technologies can be combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the scope of protection of the embodiments of the present application. The embodiments of the present application include at least part of the following contents.

[0111] FIG5 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG5 , the wireless communication method 200 may include at least part of the following contents:

[0113] S220: The STA receives the first information.

[0114] It should be understood that FIG5 shows the steps or operations of the wireless communication method 200, but these steps or operations are merely examples, and the embodiments of the present application may also perform other operations or variations of the operations in FIG5.

[0115] In some embodiments, the service flows described in the embodiments of the present application include at least time-sensitive service flows (also referred to as low-latency service flows). Of course, the service flows described in the embodiments of the present application may also include service flows divided according to other standards, such as service flows divided according to QoS level, data volume, etc., and this application is not limited to this.

[0116] In an embodiment of the present application, the STA can obtain the QoS parameter information of the service flow transmission that the first AP can support on the first channel, so that the STA can perform subsequent transmission of the service flow (such as delay-sensitive service flow) based on the obtained QoS parameter information of the service flow transmission that the first AP can support on the first channel to optimize the service flow transmission performance.

[0117] In some embodiments, the first channel may be one or more channels within the operating bandwidth of the BSS corresponding to the first AP. In some embodiments, the first channel may be the channel on which the first AP is currently operating, or may be another channel; for example, the first channel may be one or more channels agreed upon by a protocol, or may be one or more pre-configured channels, or may be one or more channels determined by pre-negotiation, which is not limited in this application.

[0118] In some embodiments, the first AP may be the AP itself that sends the first information, or the first AP may be a neighboring AP of the AP that sends the first information, or the first AP may be another AP that is located in the same co-located AP set as the AP that sends the first information, or the first AP may be another AP that is located in the same multiple Basic Service Set Identifier (BSSID) set as the AP that sends the first information.

[0119] For example, when the first AP is different from the AP that sends the first information, the AP that sends the first information may obtain the first information or information related to the first information from the first AP.

[0120] The embodiments of the present application may also be applied to a multi-link device (MLD).

[0121] For example, the above S210 may be replaced by: the AP MLD sends information X, where the information X includes at least QoS parameter information for service flow transmission that the AP MLD can support on the first channel; and the above S220 may be replaced by: the non-AP MLD receives the information X. Specifically, the non-AP MLD may perform subsequent transmission of a service flow (e.g., a delay-sensitive service flow) based on the acquired QoS parameter information for service flow transmission that the AP MLD can support on the first channel, thereby optimizing service flow transmission performance.

[0122] For another example, the above S210 may be replaced by: the AP MLD sends information X, where the information X includes at least QoS parameter information of service flow transmission supported by one or more subordinate APs of the AP MLD on the first channel; and the above S220 may be replaced by: the non-AP MLD receives the information X. Specifically, the non-AP MLD may perform subsequent transmission of service flows (such as delay-sensitive service flows) based on the obtained QoS parameter information of service flow transmission supported by one or more subordinate APs of the AP MLD on the first channel, thereby optimizing service flow transmission performance.

[0123] In some embodiments, the service flow transmission QoS parameter information that can be supported by the first AP on the first channel is associated with the service flow transmission QoS parameter evaluation result of the first BSS within the first evaluation time period.

[0124] Specifically, the first AP evaluates the transmission QoS parameters of the service flow (such as delay-sensitive service flow) of the first BSS within the first evaluation time period to obtain or obtain the evaluation result of the service flow transmission QoS parameters of the first BSS within the first evaluation time period.

[0125] For example, the first AP filters out the service flow transmission QoS parameter information that the first AP can support on the first channel based on the service flow transmission QoS parameter evaluation result of the first BSS within the first evaluation time period.

[0126] In some embodiments, the first evaluation duration may be agreed upon by a protocol, or the first evaluation duration may be configured by the first AP or the first AP, or the first evaluation duration may be configured by the physical AP MLD or the logical AP MLD to which the first AP belongs.

[0127] In some embodiments, the first evaluation duration may be a plurality of preset beacon intervals.

[0128] In some embodiments, the first BSS may be any BSS corresponding to the first AP, or the first BSS may be a specific BSS corresponding to the first AP. For example, the specific BSS is the BSS where the STA currently resides, or the specific BSS is the BSS with the most delay-sensitive services among all BSSs corresponding to the first AP, or the specific BSS is the BSS with the largest amount of delay-sensitive services among all BSSs corresponding to the first AP, or the specific BSS is the BSS with the smallest identifier among all BSSs corresponding to the first AP, or the specific BSS is the BSS with the largest identifier among all BSSs corresponding to the first AP, or the specific BSS is any BSS associated with R-TWT among all BSSs corresponding to the first AP, or the specific BSS is the BSS with the smallest identifier among all BSSs associated with R-TWT among all BSSs corresponding to the first AP, or the specific BSS is the BSS with the largest identifier among all BSSs associated with R-TWT among all BSSs corresponding to the first AP.

[0129] In some embodiments, the evaluation result of the service flow transmission QoS parameter of the first BSS within the first evaluation time period is associated with an available service time parameter in the first BSS within the first evaluation time period;

[0130] The available service time parameter includes but is not limited to at least one of the following: an available minimum service duration, an available maximum service duration, an available minimum service interval, and an available maximum service interval.

[0131] For example, the first AP evaluates the QoS parameters of the service flow (such as delay-sensitive service flow) transmission of the first BSS within the first evaluation period based on the available service time parameters in the first BSS within the first evaluation period, so as to obtain or get the evaluation results of the QoS parameters of the service flow transmission of the first BSS within the first evaluation period.

[0132] For example, the available service time parameter in the first BSS within the first evaluation duration includes the minimum available service duration. That is, the first AP evaluates the transmission QoS parameters of service flows (e.g., delay-sensitive service flows) of the first BSS within the first evaluation duration based on the minimum available service duration in the first BSS within the first evaluation duration, to obtain or acquire an evaluation result of the transmission QoS parameters of the service flows of the first BSS within the first evaluation duration.

[0133] For example, the available service time parameter in the first BSS within the first evaluation duration includes the maximum available service duration. That is, the first AP evaluates the transmission QoS parameters of service flows (e.g., delay-sensitive service flows) of the first BSS within the first evaluation duration based on the maximum available service duration in the first BSS within the first evaluation duration, to obtain or acquire an evaluation result of the transmission QoS parameters of the service flows of the first BSS within the first evaluation duration.

[0134] For example, the available service time parameter in the first BSS during the first evaluation duration includes the available minimum service interval. That is, the first AP evaluates the transmission QoS parameters of service flows (e.g., delay-sensitive service flows) of the first BSS during the first evaluation duration based on the available minimum service interval in the first BSS during the first evaluation duration, to obtain or acquire an evaluation result of the transmission QoS parameters of the service flows of the first BSS during the first evaluation duration.

[0135] For example, the available service time parameter in the first BSS during the first evaluation duration includes the maximum available service interval. That is, the first AP evaluates the transmission QoS parameters of service flows (e.g., delay-sensitive service flows) of the first BSS during the first evaluation duration based on the maximum available service interval in the first BSS during the first evaluation duration, to obtain or acquire an evaluation result of the transmission QoS parameters of the service flows of the first BSS during the first evaluation duration.

[0136] For example, the available service time parameters in the first BSS within the first evaluation duration include an available minimum service duration and an available minimum service interval. That is, the first AP evaluates the transmission QoS parameters of service flows (such as delay-sensitive service flows) of the first BSS within the first evaluation duration based on the available minimum service duration and the available minimum service interval in the first BSS within the first evaluation duration, so as to obtain or acquire an evaluation result of the transmission QoS parameters of the service flows of the first BSS within the first evaluation duration.

[0137] For example, the available service time parameters in the first BSS within the first evaluation duration include the maximum available service duration and the maximum available service interval. That is, the first AP evaluates the transmission QoS parameters of the service flow (e.g., delay-sensitive service flow) of the first BSS within the first evaluation duration based on the maximum available service duration and the maximum available service interval in the first BSS within the first evaluation duration, so as to obtain or acquire the evaluation result of the transmission QoS parameters of the service flow of the first BSS within the first evaluation duration.

[0138] For example, the available service time parameters in the first BSS within the first evaluation duration include the available minimum service duration and the available maximum service interval. That is, the first AP evaluates the transmission QoS parameters of the service flow (such as the delay-sensitive service flow) of the first BSS within the first evaluation duration based on the available minimum service duration and the available maximum service interval in the first BSS within the first evaluation duration, so as to obtain or acquire the evaluation result of the transmission QoS parameters of the service flow of the first BSS within the first evaluation duration.

[0139] For example, the available service time parameters in the first BSS within the first evaluation duration include the maximum available service duration and the minimum available service interval. That is, the first AP evaluates the transmission QoS parameters of the service flows (e.g., delay-sensitive service flows) of the first BSS within the first evaluation duration based on the maximum available service duration and the maximum available service interval in the first BSS within the first evaluation duration, to obtain or acquire an evaluation result of the transmission QoS parameters of the service flows of the first BSS within the first evaluation duration.

[0140] For example, the available service time parameters in the first BSS within the first evaluation duration include the available minimum service duration, the available maximum service duration, and the available minimum service interval. That is, the first AP evaluates the transmission QoS parameters of the service flow (such as the delay-sensitive service flow) of the first BSS within the first evaluation duration based on the available minimum service duration, the available maximum service duration, and the available minimum service interval in the first BSS within the first evaluation duration, to obtain or acquire the evaluation result of the service flow transmission QoS parameters of the first BSS within the first evaluation duration.

[0141] For example, the available service time parameters in the first BSS within the first evaluation duration include the available minimum service duration, the available maximum service duration, and the available maximum service interval. That is, the first AP evaluates the transmission QoS parameters of the service flow (such as the delay-sensitive service flow) of the first BSS within the first evaluation duration based on the available minimum service duration, the available maximum service duration, and the available maximum service interval in the first BSS within the first evaluation duration, to obtain or acquire the evaluation result of the service flow transmission QoS parameters of the first BSS within the first evaluation duration.

[0142] For example, the available service time parameters in the first BSS within the first evaluation duration include the available minimum service duration, the available minimum service interval, and the available maximum service interval. That is, the first AP evaluates the transmission QoS parameters of the service flow (such as the delay-sensitive service flow) of the first BSS within the first evaluation duration based on the available minimum service duration, the available minimum service interval, and the available maximum service interval in the first BSS within the first evaluation duration, so as to obtain or acquire the evaluation result of the service flow transmission QoS parameters of the first BSS within the first evaluation duration.

[0143] For example, the available service time parameters in the first BSS within the first evaluation duration include the available minimum service duration, the available maximum service duration, the available minimum service interval, and the available maximum service interval. That is, the first AP evaluates the transmission QoS parameters of the service flow (such as the delay-sensitive service flow) of the first BSS within the first evaluation duration based on the available minimum service duration, the available maximum service duration, the available minimum service interval, and the available maximum service interval in the first BSS within the first evaluation duration, so as to obtain or acquire the evaluation result of the service flow transmission QoS parameters of the first BSS within the first evaluation duration.

[0144] In some embodiments, the available service time parameter in the first BSS within the first evaluation duration is associated with the scheduling capability of the first AP and / or the channel condition of the first channel.

[0145] Specifically, the first AP determines an available service time parameter in the first BSS within the first evaluation duration based on its scheduling capability and / or the channel condition of the first channel.

[0146] For example, the first AP determines the available service time parameters in the first BSS within the first evaluation period based on the channel conditions of the first channel (such as the actual channel idle time and the actual channel busy time of the first channel within the first evaluation period, and the communication status between the AP and the STA).

[0147] For example, the first AP determines the available service time parameters in the first BSS within the first evaluation duration based on its scheduling capabilities (such as the scheduling and control mechanisms that the AP considers through priority acquisition of channels, R-TWT operations, etc.).

[0148] For example, the first AP determines the available service time parameters in the first BSS within the first evaluation period based on the channel conditions of the first channel (such as the actual channel idle time and the actual channel busy time of the first channel within the first evaluation period, and the communication status between the AP and the STA) and the scheduling capabilities of the first AP (such as the AP believes that scheduling and control mechanisms such as priority acquisition of channels and R-TWT operations are used).

[0149] In some embodiments, the minimum available service duration may specifically refer to: the minimum amount of service time that can be provided for service flow transmission in the first BSS within a service interval period within a first evaluation duration obtained based on the scheduling capability of the first AP and / or the channel condition of the first channel, wherein the service interval period refers to the time interval between the start times of two consecutive service durations that can be supported in the first BSS as evaluated. For example, the minimum available service duration may include an unsigned integer, with units of TU.

[0150] In some embodiments, the maximum available service duration may specifically refer to: the maximum amount of service time that can be provided for service flow transmission in the first BSS within a service interval period within a first evaluation duration obtained based on the scheduling capability of the first AP and / or the channel condition of the first channel, wherein the service interval period refers to the time interval between the start times of two consecutive service durations that can be provided in the first BSS obtained through evaluation. For example, the maximum available service duration may include an unsigned integer, with units of TU.

[0151] In some embodiments, the available minimum service interval may specifically refer to: the minimum time interval between the start times of two consecutive service durations in the first BSS within a first evaluation duration obtained based on the scheduling capability of the first AP and / or the channel condition of the first channel. For example, the available minimum service interval may include an unsigned integer in microseconds.

[0152] In some embodiments, the maximum available service interval may specifically refer to: the maximum time interval between the start times of two consecutive service durations in the first BSS within a first evaluation duration obtained based on the scheduling capability of the first AP and / or the channel condition of the first channel. For example, the minimum available service interval may include an unsigned integer in microseconds.

[0153] In some embodiments, the service flow transmission QoS parameters (such as the minimum available service duration, the maximum available service duration, the minimum available service interval, the maximum available service interval, etc.) in the first BSS within a first evaluation period (such as multiple preset beacon intervals) can be evaluated, as shown in Figure 6.

[0154] In some embodiments, the first information further includes an available service time parameter in the first BSS within the first evaluation duration. That is, the first information includes QoS parameter information of service flow transmission that the first AP can support on the first channel and an available service time parameter in the first BSS within the first evaluation duration.

[0155] In some embodiments, the service flow transmission QoS parameter information supportable by the first AP on the first channel is associated with the service flow transmission QoS parameter evaluation result during N service periods in the first BSS within the first evaluation duration, where N is a positive integer.

[0156] Specifically, the first AP evaluates the transmission QoS parameters of service flows (such as delay-sensitive service flows) during N service cycles in the first BSS within the first evaluation time period to obtain or obtain the evaluation results of the transmission QoS parameters of service flows during N service cycles in the first BSS within the first evaluation time period.

[0157] Specifically, for example, the first AP filters out service flow transmission QoS parameter information that the first AP can support on the first channel based on a service flow transmission QoS parameter evaluation result during N service periods in the first BSS within a first evaluation duration.

[0158] In some embodiments, the first evaluation duration may be agreed upon by a protocol, or the first evaluation duration may be configured by the AP or the first AP, or the first evaluation duration may be configured by the physical AP MLD or logical AP MLD to which the first AP belongs.

[0159] In some embodiments, the first evaluation duration may be a plurality of preset beacon intervals.

[0160] In some embodiments, the first BSS may be any BSS corresponding to the first AP, or the first BSS may be a specific BSS corresponding to the first AP. For example, the specific BSS is the BSS where the STA currently resides, or the specific BSS is the BSS with the most delay-sensitive services among all BSSs corresponding to the first AP, or the specific BSS is the BSS with the largest amount of delay-sensitive services among all BSSs corresponding to the first AP, or the specific BSS is the BSS with the smallest identifier among all BSSs corresponding to the first AP, or the specific BSS is the BSS with the largest identifier among all BSSs corresponding to the first AP, or the specific BSS is any BSS associated with R-TWT among all BSSs corresponding to the first AP, or the specific BSS is the BSS with the smallest identifier among all BSSs associated with R-TWT among all BSSs corresponding to the first AP, or the specific BSS is the BSS with the largest identifier among all BSSs associated with R-TWT among all BSSs corresponding to the first AP.

[0161] In some embodiments, the N service periods are service periods for which service flow scheduling and transmission are to be performed in the first BSS, or the N service periods are service periods for which service flow scheduling and transmission have been performed in the first BSS.

[0162] In some embodiments, the service flow transmission QoS parameter evaluation result during N service periods in the first BSS within the first evaluation duration is associated with an available service time parameter during N service periods in the first BSS within the first evaluation duration;

[0163] The available service time parameter includes but is not limited to at least one of the following: an available minimum service duration, an available maximum service duration, an available minimum service interval, and an available maximum service interval.

[0164] For example, the first AP evaluates the transmission QoS parameters of service flows (such as delay-sensitive service flows) during N service cycles in the first BSS during the first evaluation period based on the available service time parameters during N service cycles in the first BSS during the first evaluation period to obtain the evaluation results of the transmission QoS parameters of service flows during N service cycles in the first BSS during the first evaluation period.

[0165] For example, the available service time parameters during the N service periods in the first BSS within the first evaluation duration include the available minimum service duration. That is, the first AP evaluates the transmission QoS parameters of service flows (such as delay-sensitive service flows) of the first BSS within the first evaluation duration based on the available minimum service duration during the N service periods in the first BSS within the first evaluation duration, so as to obtain or acquire an evaluation result of the transmission QoS parameters of the service flows during the N service periods in the first BSS within the first evaluation duration.

[0166] For example, the available service time parameters during the N service periods in the first BSS within the first evaluation duration include the maximum available service duration. That is, the first AP evaluates the transmission QoS parameters of the service flow (e.g., delay-sensitive service flow) during the N service periods in the first BSS within the first evaluation duration based on the maximum available service duration during the N service periods in the first BSS within the first evaluation duration, so as to obtain or acquire an evaluation result of the transmission QoS parameters of the service flow during the N service periods in the first BSS within the first evaluation duration.

[0177] In some embodiments, the available service time parameter during the N service periods in the first BSS within the first evaluation duration is associated with a scheduling capability of the first AP and / or a channel condition of the first channel.

[0178] Specifically, the first AP determines the available service time parameters during N service periods in the first BSS within the first evaluation duration based on its scheduling capability and / or the channel condition of the first channel.

[0179] For example, the first AP determines the available service time parameters during N service cycles in the first BSS within the first evaluation period based on the channel conditions of the first channel (such as the actual channel idle time and the actual channel busy time of the first channel within the first evaluation period, and the communication status between the first AP and the STA).

[0180] For example, the first AP determines the available service time parameters during N service cycles in the first BSS within the first evaluation duration based on its scheduling capabilities (such as the first AP believes that scheduling and control mechanisms such as priority channel acquisition and R-TWT operations are used).

[0181] For example, the first AP determines the available service time parameters during N service cycles in the first BSS within the first evaluation period based on the channel conditions of the first channel (such as the actual channel idle time and the actual channel busy time of the first channel within the first evaluation period, and the communication status between the first AP and the STA) and the scheduling capabilities of the first AP (such as the scheduling and control mechanisms such as priority acquisition of channels and R-TWT operations that the AP believes in).

[0182] In some embodiments, the N service periods are R-TWT service periods corresponding to one or more R-TWT schedules established in the first BSS within the first evaluation duration.

[0183] In some embodiments, the minimum available service duration may specifically refer to: the minimum amount of service time that can be provided for service flow transmission within a service interval period during N service cycles in the first BSS within a first evaluation duration obtained based on the scheduling capability of the first AP and / or the channel condition of the first channel, wherein the service interval period refers to the time interval between the start times of two consecutive service durations that can be supported during the N service cycles in the first BSS obtained through evaluation.

For example, the minimum available service interval may include an unsigned integer expressed in microseconds.

[0187] In some embodiments, the QoS parameters of service flow transmission (such as the minimum available service duration, the maximum available service duration, the minimum available service interval, the maximum available service interval, etc.) during N service periods for service flow scheduling and transmission to be performed in the first BSS within a first evaluation duration (such as multiple preset beacon intervals) (such as the R-TWT service period corresponding to a specific R-TWT scheduling established in the first BSS) can be evaluated, as shown in Figure 7. Specifically, Figure 7 is a scenario for evaluating service flow transmission QoS parameters for a service period for service flow scheduling and transmission to be performed for a specific R-TWT scheduling (such as a newly established R-TWT).

[0188] In some embodiments, the QoS parameters of service flow transmission (such as the minimum available service duration, the maximum available service duration, the minimum available service interval, the maximum available service interval, etc.) during N service periods (such as the R-TWT service period corresponding to a specific R-TWT scheduling established in the first BSS) in which service flow scheduling and transmission have been performed in the first BSS within a first evaluation duration (such as multiple preset beacon intervals) can be evaluated, as shown in Figure 8. Specifically, Figure 8 shows a scenario in which the QoS parameters of service flow transmission are evaluated for the service period in which corresponding service flow scheduling and transmission have been performed for a specific R-TWT scheduling.

[0189] In some embodiments, the first information further includes available service time parameters during N service periods in the first BSS within the first evaluation duration. That is, the first information includes QoS parameter information for service flow transmission supportable by the first AP on the first channel and available service time parameters during N service periods in the first BSS within the first evaluation duration.

[0190] In some embodiments, the STA selects an AP and / or link for transmitting a service flow (such as a delay-sensitive service flow) based on the first information. Thus, the STA can select an AP and / or link that is more conducive to transmitting the delay-sensitive service flow.

[0191] In some embodiments, the STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP and to be joined based on the first information, and / or the STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target link and to be joined based on the first information. Thus, the STA can select the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP and to be joined that is more conducive to the transmission of business flows (such as delay-sensitive business flows), or the STA can select the broadcast TWT corresponding to the target R-TWT scheduling established by the target link and to be joined that is more conducive to the transmission of business flows (such as delay-sensitive business flows).

[0192] In some embodiments, the target AP is configured or indicated by the AP or the first AP, or the target AP is determined by the STA. For example, the target AP is an AP selected for delay-sensitive services, or the target AP is any AP selected for delay-sensitive services.

[0193] In some embodiments, the target link is configured or indicated by the AP or the first AP, or the target link is determined by the STA. For example, the target link is a link selected for delay-sensitive services, or the target link is any link selected for delay-sensitive services.

[0194] In some embodiments, the target R-TWT schedule is configured or indicated by the AP or the first AP, or the target R-TWT schedule is determined by the STA.

[0195] For example, the STA selects the AP and / or link for transmitting service flows (such as delay-sensitive service flows) based on the first information, and the STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP and to be joined based on the first information.

[0196] For example, the STA selects the AP and / or link for transmitting service flows (such as delay-sensitive service flows) based on the first information, and the STA selects the broadcast TWT corresponding to the target R-TWT scheduling established on the target link and to be joined based on the first information.

[0197] For example, the STA selects the AP and / or link for transmitting service flows (such as delay-sensitive service flows) based on the first information, the STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP and to be joined based on the first information, and the STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target link and to be joined based on the first information.

[0198] In some embodiments, the service flow transmission QoS parameter information supportable by the first AP on the first channel includes m supportable service flow transmission QoS parameter sets, wherein the supportable service flow transmission QoS parameter sets in the m supportable service flow transmission QoS parameter sets include but are not limited to at least one of the following QoS parameters: estimated delay bound, estimated MSDU delivery ratio, estimated MSDU count index, estimated maximum MSDU size, estimated burst size, estimated averaging window, estimated minimum data rate, and estimated maximum data rate.

[0199] Wherein, m is a positive integer, and m=1 or m≥2.

[0200] In some embodiments, when m≥2, the values ​​of some or all QoS parameters included in different supportable service flow transmission QoS parameter sets among the m supportable service flow transmission QoS parameter sets are different.

[0201] In some embodiments, the value of m is agreed upon by a protocol, or the value of m is determined by an AP.

[0202] For example, an estimated delay bound includes an unsigned integer defining an estimated maximum time (in microseconds) that can be achieved for transmitting an MSDU or A-MSDU of a specific service flow (e.g., based on the scheduling capability of the first AP and / or the channel condition of the first channel), where the maximum time is estimated from the time when the first MSDU of the MSDU constituting the A-MSDU arrives at the local (or source) MAC SAP at the local (or source) MAC sublayer to the completion time when the MSDU or A-MSDU is successfully transmitted or retransmitted to the destination. The completion time of the MSDU or A-MSDU transmission includes the corresponding acknowledgment frame transmission time.

[0203] For example, the estimated MSDU Delivery Ratio is used to indicate the percentage of MSDUs or A-MSDUs that can be successfully transmitted within the delay limit specified by the "evaluated delay limit" (such as based on the first AP scheduling capability and / or the channel conditions of the first channel).

[0204] For example, the estimated MSDU count index includes an unsigned integer that specifies an index of the number of incoming MSDUs used to calculate the estimated MSDU transmission rate. The number of incoming MSDUs is equal to the estimated MSDU count index of 10.

[0205] For example, the estimated maximum MSDU size includes an unsigned integer that specifies the maximum length (in bytes) of an MSDU or A-MSDU used to evaluate the QoS parameters of a service flow.

[0206] For example, the estimated burst size contains an unsigned integer that specifies the maximum burst (in bytes) of MSDUs or A-MSDUs belonging to the service flow estimated to arrive at the MAC SAP within the duration specified in the estimated delay bound.

[0207] For example, the evaluation averaging window contains an unsigned integer that is used to evaluate the duration of the minimum data rate and the maximum data rate, in units of TU.

[0208] For example, the estimated minimum data rate includes an unsigned integer, which is used to define the lowest data rate that can be supported for transmitting the MSDU or A-MSDU of a specific service flow at the MAC SAP, in kilobits per second.

[0209] For example, the estimated maximum data rate includes an unsigned integer, which is used to define the estimated maximum data rate of the MSDU or A-MSDU that can be supported for transmitting a specific service flow at the MAC SAP, in kilobits per second.

[0244] In some embodiments, different service flow transmission QoS parameter sets in the service flow transmission QoS parameter set list have different values ​​for some or all of the QoS parameters.

[0245] For example, the service flow transmission QoS parameter set list may be as shown in Table 2, wherein the values ​​of some or all QoS parameters contained in different service flow transmission QoS parameter sets in the service flow transmission QoS parameter set list are different.

[0246] Table 2

[0247] It should be noted that in the above Table 2, the type and / or order of the QoS parameters in the service flow transmission QoS parameter set can be adjusted based on demand, and this application does not limit this.

[0248] Specifically, STA can perform subsequent transmission of service flows (such as delay-sensitive service flows) based on the supportable service flow transmission QoS parameter set identification bitmap (for example, selecting APs and / or links for delay-sensitive service flow transmission, or selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, or selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined) to optimize the delay-sensitive service transmission performance based on R-TWT.

[0249] For example, the supported service flow transmission QoS parameter set identification bitmap indicates the QoS type and / or corresponding QoS characteristics of the service corresponding to the supported service flow. The value 1 in bit position i of the supported service flow transmission QoS parameter set identification bitmap indicates that the QoS type and / or corresponding QoS characteristics of the service corresponding to the QoS identification value i are supported, and the value 0 in bit position i of the supported service flow transmission QoS parameter set identification bitmap indicates that the QoS type and / or corresponding QoS characteristics of the service corresponding to the QoS identification value i are not supported. Among them, the QoS identification value can be defined as an identification of a service that is generally assumed to be frequently used. Therefore, by establishing a mapping relationship between the QoS identification value and a pre-defined or pre-configured (or standardized) service QoS characteristic parameter (including one or more parameters defined in the supported service flow transmission QoS parameter information field format 1), the service type and / or corresponding QoS characteristics corresponding to the QoS identification value are determined, so that the supported service flow transmission QoS parameter set identification bitmap can be used in signaling to reduce signaling overhead.

[0250] In some embodiments, the service flow transmission QoS parameter set list is agreed upon by a protocol, or the service flow transmission QoS parameter set list is configured by the AP.

[0252] Specifically, for example, the first information includes the operation and capability parameter information of the STA recommended based on the QoS parameter information of the service flow transmission supported by the first AP on the first channel.

[0373] In some embodiments, since the evaluation of service flow transmission QoS parameters is performed based on the AP scheduling capability and channel conditions, the evaluation of service flow transmission QoS parameters such as the minimum service duration available, the maximum service duration available, the minimum service interval available, and the maximum service interval available during the evaluation period can be based on the actual channel idle time and the actual channel busy time during the evaluation period and the communication between the AP and its site. It can also be evaluated not according to the actual channel idle time and the actual channel busy time but based on the AP scheduling capability (that is, the AP believes that the service flow transmission capability that can be achieved through scheduling and control mechanisms such as priority channel acquisition and R-TWT operation).

[0374] Specifically, as shown in FIG9 , the evaluation of QoS parameters for a service flow (such as a delay-sensitive service flow) based on AP scheduling capabilities and channel conditions mainly includes the following steps:

[0381] The Available Service Time Parameters field is used to indicate the available service time parameters during N R-TWT service periods in the first BSS within the first evaluation duration. The service flow transmission QoS parameter information supportable by the first AP on the first channel is associated with the available service time parameters during N R-TWT service periods in the first BSS within the first evaluation duration, where N is a positive integer.

[0382] The Recommended STA Operation and Capability field is used to indicate the operation and capability parameter information of the STA recommended based on the service flow transmission QoS parameter information supportable by the first AP on the first channel;

[0384] For example, the evaluation of the supportable service flow transmission QoS parameter information field can be shown in Figure 10. The evaluation of the supportable service flow transmission QoS parameter information field can include: supportable service flow transmission QoS parameter field, available service time parameter field, recommended site operation and capability parameter field and recommended site transceiver parameter field.

[0396] Table 4 Direction field encoding

[0397] It should be noted that the meaning of each bit in Table 3 and Table 4 above can be flexibly adjusted based on needs.

[0398] Specifically, whether to use the QoS parameter set identification bitmap field is used to indicate whether the supportable service flow transmission QoS parameter field in the supportable service flow transmission QoS parameter information field is evaluated to use the supportable service flow transmission QoS parameter set identification bitmap field. For example, whether to use the QoS parameter set identification bitmap field occupies 1 bit; when it is set to 1, it indicates that the supportable service flow transmission QoS parameter set identification bitmap field is used, and when it is set to 0, it indicates that the supportable service flow transmission QoS parameter set identification bitmap field is not used; or, when it is set to 0, it indicates that the supportable service flow transmission QoS parameter set identification bitmap field is used, and when it is set to 1, it indicates that the supportable service flow transmission QoS parameter set identification bitmap field is not used.

[0399] In some embodiments, the supportable service flow transmission QoS parameter set identification bitmap size field and the supportable service flow transmission QoS parameter quantity field share multiple bits;

[0400] Among them, when the QoS parameter set identification bitmap field is used to indicate whether the supportable service flow transmission QoS parameter field uses the supportable service flow transmission QoS parameter set identification bitmap field to indicate the service flow transmission QoS parameter information that the first AP can support on the first channel, the multiple bits only correspond to the supportable service flow transmission QoS parameter set identification bitmap size field; and / or, when the QoS parameter set identification bitmap field is used to indicate that the supportable service flow transmission QoS parameter field does not use the supportable service flow transmission QoS parameter set identification bitmap field to indicate the service flow transmission QoS parameter information that the first AP can support on the first channel, the multiple bits only correspond to the supportable service flow transmission QoS parameter number field.

[0401] For example, the control field for evaluating the supportable service flow transmission QoS parameters can be as shown in Figure 11, which may include a direction field (occupying 2 bits), whether to use the QoS parameter set identification bitmap field (occupying 1 bit), supportable service flow transmission QoS parameter set identification bitmap size field / supportable service flow transmission QoS parameter number field (occupying 4 bits), supportable service flow transmission QoS parameter existence bitmap field (occupying 8 bits), recommended site operation and capability parameter existence field (occupying 1 bit), and recommended site transceiver parameter existence field (occupying 1 bit).

[0402] For example, when the QoS parameter set identification bitmap field is used to indicate the supportable service flow transmission QoS parameter field and the supportable service flow transmission QoS parameter set identification bitmap field is used to indicate the service flow transmission QoS parameter information that the first AP can support on the first channel, the evaluation of the supportable service flow transmission QoS parameter control field can be as shown in Figure 12, which may include a direction field (occupying 2 bits), whether to use the QoS parameter set identification bitmap field (occupying 1 bit), supportable service flow transmission QoS parameter set identification bitmap size field (occupying 4 bits), supportable service flow transmission QoS parameter existence bitmap field (occupying 8 bits), recommended site operation and capability parameter existence field (occupying 1 bit), and recommended site transceiver parameter existence field (occupying 1 bit).

[0404] Specifically, the recommended site operation and capability parameter existence field indicates whether the recommended site operation and capability parameter field exists in the evaluation supportable service flow transmission QoS parameter information field; wherein, if the recommended site operation and capability parameter existence field is set to 1, it indicates that the recommended site operation and capability parameter field exists in the evaluation supportable service flow transmission QoS parameter information field; if the recommended site operation and capability parameter existence field is set to 0, it indicates that the recommended site operation and capability parameter field does not exist in the evaluation supportable service flow transmission QoS parameter information field. Alternatively, the recommended site operation and capability parameter existence field is set to 0, indicating that the recommended site operation and capability parameter field exists in the evaluation supportable service flow transmission QoS parameter information field; if the recommended site operation and capability parameter existence field is set to 1, it indicates that the recommended site operation and capability parameter field does not exist in the evaluation supportable service flow transmission QoS parameter information field.

[0405] Specifically, the Recommended Site Transceiver Parameters Existence field indicates whether a Recommended Site Transceiver Parameters field exists in the Evaluated Supportable Service Flow Transmission QoS Parameter Information field. If the Recommended Site Transceiver Parameters Existence field is set to 1, it indicates that a Recommended Site Transceiver Parameters field exists in the Evaluated Supportable Service Flow Transmission QoS Parameter Information field. If the Recommended Site Transceiver Parameters Existence field is set to 0, it indicates that a Recommended Site Transceiver Parameters field does not exist in the Evaluated Supportable Service Flow Transmission QoS Parameter Information field. Alternatively, if the Recommended Site Transceiver Parameters Existence field is set to 0, it indicates that a Recommended Site Transceiver Parameters field exists in the Evaluated Supportable Service Flow Transmission QoS Parameter Information field. If the Recommended Site Transceiver Parameters Existence field is set to 1, it indicates that a Recommended Site Transceiver Parameters field does not exist in the Evaluated Supportable Service Flow Transmission QoS Parameter Information field.

[0406] In some embodiments, when the QoS parameter set identification bitmap field is used to indicate that the supportable service flow transmission QoS parameter field does not use the supportable service flow transmission QoS parameter set identification bitmap field to indicate the service flow transmission QoS parameter information supportable by the first AP on the first channel, the supportable service flow transmission QoS parameter field includes m supportable service flow transmission QoS parameter set fields, where m is a positive integer, and m=1 or m≥2;

[0409] In some embodiments, when m≥2, the values ​​of some or all of the QoS parameters indicated in different supportable service flow transmission QoS parameter set fields in the m supportable service flow transmission QoS parameter set fields are different.

[0410] Specifically, when the QoS parameter set identification bitmap field is used to indicate the supportable service flow transmission QoS parameter field and the supportable service flow transmission QoS parameter set identification bitmap field is not used to indicate the service flow transmission QoS parameter information that the first AP can support on the first channel, the supportable service flow transmission QoS parameter field can be as shown in Figure 14, which may include m supportable service flow transmission QoS parameter set fields; wherein each supportable service flow transmission QoS parameter set field in the m supportable service flow transmission QoS parameter set fields includes at least one of the following: an estimated delay limit (Estimated Delay Bound) field (occupies 0 or 3 bytes, that is, this field is an optional field), an estimated MSDU delivery rate (Estimated MSDU Delivery Ratio) field (occupies 0 or 1 byte, that is, this field is an optional field), an estimated MSDU count index (Estimated MSDU Count Exponent) field (occupies 0 or 1 byte, that is, this field is an optional field), an estimated maximum MSDU size (Estimated MSDU The Estimated Burst Size field (occupies 0 or 2 bytes, that is, this field is optional), the Estimated Burst Size field (occupies 0 or 4 bytes, that is, this field is optional), the Estimated Averaging Window field (occupies 0 or 2 bytes, that is, this field is optional), the Estimated Minimum Data Rate field (occupies 0 or 3 bytes, that is, this field is optional), and the Estimated Maximum Data Rate field (occupies 0 or 3 bytes, that is, this field is optional).

[0411] In some embodiments, at least one field corresponding to the supportable service flow transmission QoS parameter presence bitmap field shown in FIG11 to FIG13 includes part or all of the following fields:

[0412] The evaluated delay limit field, the evaluated MSDU transmission rate field, the evaluated MSDU count index field, the evaluated maximum MSDU size field, the evaluated burst size field, the evaluated average window field, the evaluated minimum data rate field, and the evaluated maximum data rate field.

[0413] Specifically, the bitmap field of the supported service flow transmission QoS parameters contains a bitmap, as shown in Figures 11 to 13. If the i-th field starting from the "Evaluated Delay Limit" field exists in the supported service flow transmission QoS parameter set field, the i-th item of the bitmap is set to 1; if the i-th subfield starting from the "Evaluated Delay Limit" field does not exist in the supported service flow transmission QoS parameter set field, the i-th item of the bitmap is set to 0.

[0414] Specifically, the estimated delay limit field contains an unsigned integer that defines the maximum amount of time (in microseconds) that can be achieved for transmitting an MSDU or A-MSDU of a specific service flow, as assessed (e.g., based on AP scheduling capabilities and channel conditions). The maximum amount of time is assessed from the time the first MSDU of the MSDU that is marked in the local (or source) MAC SAP at the local (or source) MAC sublayer or the MSDU that constitutes the A-MSDU arrives to the time the MSDU or A-MSDU is successfully transmitted or retransmitted to the destination. The completion time of the MSDU or A-MSDU transmission includes the corresponding acknowledgment frame transmission time.

[0415] Specifically, the Estimated MSDU Transmission Rate field is used to indicate the percentage of MSDUs or A-MSDUs that are estimated (e.g., based on AP scheduling capabilities and channel conditions) to be successfully transmitted within the delay limit specified by the Estimated Delay Limit field. The Estimated MSDU Transmission Rate subfield may be encoded as defined in Table 5 (Estimated MSDU Transmission Rate Subfield Values).

[0416] Table 5 Evaluated MSDU Transmission Rate Field Values

[0417] Specifically, the Estimated MSDU Count Index field contains an unsigned integer that specifies the index of the number of incoming MSDUs used to calculate the estimated MSDU transmission rate. The number of incoming MSDUs is equal to the Estimated MSDU Count Index of 10.

[0418] Specifically, the Evaluated Maximum MSDU Size field contains an unsigned integer that specifies the maximum length (in bytes) of an MSDU or A-MSDU used to evaluate the QoS parameters of a service flow.

[0419] Specifically, the Estimated Burst Size field contains an unsigned integer that specifies the maximum burst (in bytes) of MSDUs or A-MSDUs belonging to the service flow that arrives at the Media Access Control (MAC) Service Access Point (SAP) within the duration specified in the Estimated Delay Bound field.

[0420] Specifically, the evaluated averaging window field contains an unsigned integer that specifies the duration for evaluating the minimum data rate and the maximum data rate, in units of TU.

[0421] Specifically, the estimated minimum data rate field contains an unsigned integer that is used to define the estimated minimum data rate for transmitting an MSDU or A-MSDU of a specific service flow at the MAC SAP, in kilobits per second.

[0422] Specifically, the estimated maximum data rate field contains an unsigned integer that is used to define the estimated maximum data rate of the MSDU or A-MSDU that can be supported for transmitting a specific service flow at the MAC SAP, in kilobits per second.

[0423] In some embodiments, when the QoS parameter set identification bitmap field is used to indicate that the supportable service flow transmission QoS parameter field uses the supportable service flow transmission QoS parameter set identification bitmap field to indicate the service flow transmission QoS parameter information that the first AP can support on the first channel, the supportable service flow transmission QoS parameter field includes a supportable service flow transmission QoS parameter set identification bitmap field;

[0426] Among them, different service flow transmission QoS parameter sets in the service flow transmission QoS parameter set list have different values ​​for some or all of the QoS parameters included in them.

[0427] Specifically, when the QoS parameter set identification bitmap field is used to indicate the supportable service flow transmission QoS parameter field and the supportable service flow transmission QoS parameter set identification bitmap field is used to indicate the service flow transmission QoS parameter information that the first AP can support on the first channel, the supportable service flow transmission QoS parameter field can be as shown in Figure 15.

[0428] Specifically, the "Whether to Use the QoS Parameter Set Identification Bitmap" field is used to indicate whether the "Supported Service Stream Transmission QoS Parameters" field in the "Supported Service Stream Transmission QoS Parameters Information" field is evaluated to use the "Supported Service Stream Transmission QoS Parameters" field. For example, the "Whether to Use the QoS Parameter Set Identification Bitmap" field occupies one bit. When the "Whether to Use the QoS Parameter Set Identification Bitmap" field is set to 1, it indicates that the "Supported Service Stream Transmission QoS Parameters" field is used. The "Supported Service Stream Transmission QoS Parameters" field may be as shown in FIG15 . When the "Whether to Use the QoS Parameter Set Identification Bitmap" field is set to 0, it indicates that the "Supported Service Stream Transmission QoS Parameters" field is not used. The "Supported Service Stream Transmission QoS Parameters" field may be as shown in FIG14 . Alternatively, when the "Whether to Use the QoS Parameter Set Identification Bitmap" field is set to 0, it indicates that the "Supported Service Stream Transmission QoS Parameters" field is used. The "Supported Service Stream Transmission QoS Parameters" field may be as shown in FIG15 . When the "Whether to Use the QoS Parameter Set Identification Bitmap" field is set to 1, it indicates that the "Supported Service Stream Transmission QoS Parameters" field is not used. The "Supported Service Stream Transmission QoS Parameters" field may be as shown in FIG14 .

[0429] In some embodiments, the supported service flow transmission QoS parameter set identification bitmap field indicates the QoS type and / or corresponding QoS characteristics of the service corresponding to the supported service flow. A value of 1 in bit position i of the supported service flow transmission QoS parameter set identification bitmap field indicates that the QoS type and / or corresponding QoS characteristics of the service corresponding to the QoS identification value i are supported. A value of 0 in bit position i of the supported service flow transmission QoS parameter set identification bitmap field indicates that the QoS type and / or corresponding QoS characteristics of the service corresponding to the QoS identification value i are not supported. Among them, the QoS identification value can be defined as identifying a service that is generally assumed to be frequently used. Therefore, by establishing a mapping relationship between the QoS identification value and a pre-defined or pre-configured (or standardized) service QoS characteristic parameter (including one or more parameters defined in the supported service flow transmission QoS parameter field as shown in Figure 14), the service type and / or corresponding QoS characteristics corresponding to the QoS identification value are determined, so that the QoS identification value can be used in signaling to reduce signaling overhead.

[0452] For example, the recommended site receiving and sending parameter field can be as shown in Figure 18, which may include: NSS field (occupying 3 bits), MCS field (occupying 4 bits), DCM field (occupying 1 bit), RU allocation field (occupying 8 bits), and BW field (occupying 3 bits).

[0453] In some embodiments, the first element is an element for evaluating supportable service flow transmission QoS parameters. For example, the element for evaluating supportable service flow transmission QoS parameters may be as shown in FIG19 , which may include an evaluation supportable service flow transmission QoS parameter control field (occupying 3 bytes) and an evaluation supportable service flow transmission QoS parameter information field (occupying a variable number of bytes).

[0454] In some embodiments, the first element is a R-TWT element.

[0455] In some embodiments, when the first element is an R-TWT element, the first element includes an evaluation supportable service flow transmission QoS parameter field; wherein, the evaluation supportable service flow transmission QoS parameter field includes: the evaluation supportable service flow transmission QoS parameter information field and the evaluation supportable service flow transmission QoS parameter control field.

[0456] For example, the R-TWT element may be as shown in FIG20, which may include an evaluation supportable service flow transmission QoS parameter field (the number of bytes occupied is variable). The evaluation supportable service flow transmission QoS parameter field may be as shown in FIG21, which may include: the evaluation supportable service flow transmission QoS parameter information field and the evaluation supportable service flow transmission QoS parameter control field.

[0457] In some embodiments, when the first element is an R-TWT element, the first element also includes a field for evaluating the existence of supportable service flow transmission QoS parameters; wherein the field for evaluating the existence of supportable service flow transmission QoS parameters is used to indicate whether the field for evaluating the existence of supportable service flow transmission QoS parameters exists in the first element.

[0458] In some embodiments, the evaluation supportable service flow transmission QoS parameter presence field is located in the broadcast TWT information field in the first element.

[0459] In some embodiments, the evaluated supportable service flow transmission QoS parameter existence field and the R-TWT traffic information existence field share at least one bit in the broadcast TWT information field, wherein, when the R-TWT traffic information field is not included in the first element, the at least one bit in the broadcast TWT information field only corresponds to the evaluated supportable service flow transmission QoS parameter existence field.

[0460] For example, the broadcast TWT information field may be as shown in FIG22 , which may include a field for evaluating the existence of supportable service flow transmission QoS parameters, and the field for evaluating the existence of supportable service flow transmission QoS parameters and the R-TWT traffic information field share one bit in the broadcast TWT information field. Wherein, in the case where the R-TWT element does not include the R-TWT traffic information field, the at least one bit in the broadcast TWT information field only corresponds to the field for evaluating the existence of supportable service flow transmission QoS parameters.

[0461] For example, when the R-TWT cycle information is announced through a management frame, that is, when the Negotiation Type subfield of the TWT element is set to 2, the R-TWT parameter set field (Restricted TWT Parameter Set field) of the R-TWT element does not include the R-TWT traffic information field. At the same time, the "R-TWT Traffic Info Present / Evaluated Supportable Service Stream Transmission QoS Parameters Present" field of the broadcast TWT information field indicates the "Evaluated Supportable Service Stream Transmission QoS Parameters Present" field. When the value of the "Evaluated Supportable Service Stream Transmission QoS Parameters Present" field is 1, it indicates that the R-TWT parameter set field of the R-TWT element includes the evaluated supportable service stream transmission QoS parameters field; when the value of the "Evaluated Supportable Service Stream Transmission QoS Parameters Present" field is 0, it indicates that the R-TWT parameter set field of the R-TWT element does not include the evaluated supportable service stream transmission QoS parameters field.

[0462] In some embodiments, when the first element is an R-TWT element, the first frame is one of the following: a beacon frame, a probe response frame, an association response frame, and a reassociation response frame.

[0463] In some embodiments, the AP evaluates the QoS parameter information for the service flow (e.g., delay-sensitive service flow) supported by the AP on the first channel based on its scheduling capabilities and / or the channel conditions of the first channel (e.g., the AP's working channel), as well as the recommended transmission flow characteristic parameters, recommended site or link operation and capabilities, and recommended site or link transceiver parameter information to achieve the evaluated service flow transmission QoS parameters. Furthermore, the AP provides other STAs with supportable (e.g., supportable based on the AP's scheduling capabilities and channel conditions) service flow transmission QoS parameter information, as well as the recommended transmission flow characteristic parameters, recommended site operation and capabilities, and recommended site transceiver parameter information for service flow transmission to achieve the evaluated service flow transmission QoS parameters, by carrying the evaluated supportable service flow transmission QoS parameter element in the transmitted beacon frames, probe response frames, (re)association response frames, and other management frames. An example of service flow transmission QoS parameter evaluation and signaling in a BSS can be shown in FIG23 , where the AP carries relevant evaluation information in beacon frames. After receiving the estimated QoS parameter information for supported service flows from the AP, other stations (such as associated non-AP STAs, non-AP STAs preparing to associate, or other APs) select an AP or link for delay-sensitive service flows using an implementation-specific AP or link selection algorithm. For example, AP1 and AP2 operate in the 2.4 GHz and 5 GHz frequency bands, respectively, with the same bandwidth. The minimum available service duration and maximum available service duration provided by AP1 are both shorter than those provided by AP2, respectively. Furthermore, the minimum available service interval and maximum available service interval provided by AP1 are both longer than those provided by AP2. Based on the service flow QoS parameter evaluation information provided by AP1 and AP2, the BSS to which AP2 belongs is more conducive to the transmission of delay-sensitive service flows. Therefore, a non-AP STA preparing to associate (such as STA1) with delay-sensitive service flow transmission requirements will preferentially associate with AP2.

[0464] In some embodiments, the AP evaluates, for a specific delay-sensitive service period (such as a specific R-TWT scheduled service period), the QoS parameter information of the service flow (such as a delay-sensitive service flow) supported by the AP on the first channel during the service period based on the AP's scheduling capabilities and / or the channel conditions of the first channel (such as the AP's working channel), as well as the recommended transmission flow characteristic parameters, recommended site or link operation and capabilities, and recommended site or link transceiver capability parameter information for achieving the evaluated service flow transmission QoS parameters. In addition, the AP includes the "Evaluated Supportable Service Flow Transmission QoS Parameter Field" information in the Restricted TWT Parameter set(s) field contained in the broadcast TWT element carried in the beacon frame, probe response frame, (re)association response frame, and other management frames sent, to announce the service flow transmission QoS parameter information corresponding to one or more specific R-TWT scheduling in the BSS, as well as the recommended transmission flow characteristic parameters, recommended site operation and capabilities, and recommended site transceiver parameter information for service flow transmission for achieving the evaluated service flow transmission QoS parameters. An example of QoS parameter evaluation and signaling for service flow transmission based on a specific R-TWT in a BSS can be shown in Figures 24 and 25, where the AP carries relevant evaluation information in the broadcast TWT element in the beacon frame.

[0465] For example, a BSS establishes two R-TWT schedules, namely R-TWT schedule 1 and R-TWT schedule 2, which have their corresponding R-TWT service periods (SPs). The available minimum service duration and the available maximum service duration provided by the R-TWT service period corresponding to R-TWT schedule 1 are respectively shorter than the available minimum service duration and the available maximum service duration provided by the R-TWT service period corresponding to R-TWT schedule 2; and the available minimum service interval and the available maximum service interval provided by the R-TWT service period corresponding to R-TWT schedule 1 are respectively longer than the available minimum service interval and the available maximum service interval provided by the R-TWT service period corresponding to R-TWT schedule 2. Judging from the service flow QoS parameter evaluation information provided by R-TWT schedule 1 and R-TWT schedule 2, R-TWT schedule 2 will be more conducive to the transmission of delay-sensitive service flows. Therefore, if a Non-AP STA (such as STA1) that is preparing to establish an R-TWT protocol with an AP has a transmission demand for delay-sensitive service flows, it will give priority to applying for member stations of the service period corresponding to R-TWT schedule 2.

[0466] Therefore, in an embodiment of the present application, the STA can obtain the QoS parameter information of the service flow transmission that the first AP can support on the first channel, so that the STA can perform subsequent transmission of the service flow (such as delay-sensitive service flow) based on the obtained QoS parameter information of the service flow transmission that the first AP can support on the first channel to optimize the service flow transmission performance.

[0467] Specifically, by providing delay-sensitive service flow transmission QoS parameter evaluation information based on the AP scheduling capability and / or the channel conditions of the AP's current channel, as well as the recommended transmission flow characteristic parameters, recommended site or link operation and capability recommended site or link transceiver capability parameter information for achieving the evaluated delay-sensitive service flow transmission QoS parameters, the site receiving the information can use the information it conveys to, firstly, select the AP or link to be used for low-latency service flow transmission in the implementation-specific AP or link selection algorithm; secondly, for a specific AP or link, select the restricted TWT corresponding to the specific restricted TWT schedule (R-TWT schedule) that the AP or link has established and intends to join.
