[0043] 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).

[0044] 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.

[0045] 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.

[0046] 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.

[0047] 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 plays the role of AP.

[0048] 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.

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.

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.

[0065] 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.

[0066] In order to facilitate a better understanding of the embodiments of the present application, the R-TWT related to the present application is explained.

[0067] 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.

[0068] 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.

[0069] 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.

[0070] 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.

[0071] 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.

[0072] To facilitate a better understanding of the embodiments of the present application, the BSS load elements related to the present application are described.

[0073] The BSS Load element contains information about the current number of STAs and traffic levels in the BSS. The element information format is shown in Figure 2 (BSS Load Unit Format). When performing a BSS transition, STAs can use this element for vendor-specific AP selection algorithms.

[0074] The Station Count field indicates the total number of STAs currently associated with the BSS.

[0075] The Channel Utilization field is defined as the percentage of time that the AP senses the medium is busy, with a linear scale of 255 representing 100%, such as the physical carrier sensing (CS) mechanism or the virtual carrier sensing (CS) mechanism. When the BSS uses multiple channels, the Channel Utilization field value is calculated only for the primary channel. This percentage is calculated using the following formula:

[0076] The channel busy time is defined as the number of microseconds that the CS mechanism indicates the channel busy indication. dot11ChannelUtilizationBeaconsIntervals indicates the number of consecutive beacon intervals used to measure the channel busy time. dot11BeaconPeriod is defined as the time period used by the station to schedule beacon transmissions, in units of TUs.

[0077] The Available Admission Capacity field contains an unsigned integer that specifies the amount of remaining medium time available through explicit admission control, in units of 32 us / s. This field helps BSS-transitioning STAs select APs that may accept future admission control requests, but it does not represent a guarantee that the hybrid coordinator (HC) will accommodate these requests.

[0078] To facilitate a better understanding of the embodiments of the present application, the HEBSS load elements related to the present application are described.

[0079] The HE BSS Load element reported by the AP contains information about utilization, frequency underutilization, and spatial stream underutilization. The element format of the HE BSS Load element (IEEE 802.11ax) is shown in Figure 3. A STA that receives the HE BSS Load element can use the information it conveys in its implementation-specific AP selection algorithm.

[0080] The HE STA count field indicates the total number of HE STAs currently associated with the BSS, which declare themselves as HE STAs by sending their HE capability elements.

[0081] The Utilization field is defined as the percentage of time that the AP detects the medium is busy due to transmissions between the AP and HE STAs. Medium busyness is indicated by the physical carrier sense (CS) mechanism, expressed on a linear scale of 255 (where 255 represents 100%). When a BSS uses multiple channels, the Utilization field value is calculated only for the primary channel. This field value is calculated using the following formula.

[0082] Among them, dot11ChannelUtilizationBeaconsIntervals represents the number of consecutive beacon intervals used to measure the channel busy time. dot11BeaconPeriod is defined as the time period used by the station to schedule beacon transmission, and the unit is TU. busy The number of microseconds that the Clear Channel Assessment (CCA) indicates that the channel is busy due to transmissions between the AP and HE STAs during the measurement duration. The resolution of the CCA busy measurement is in microseconds.

[0083] To facilitate understanding of the technical solutions of the embodiments of the present application, the problems solved by the present application are described below.

[0084] The goal of R-TWT (Restricted TWT) is to provide a protected and reliable service period for the transmission of low-latency services. The current operating rules of r-TWT do not stipulate that stations outside the TWT SP should be in doze state or unable to transmit frames to the AP, nor do they stipulate that non-scheduled stations (non-scheduled STAs) must be in doze state during the TWT SP. At the same time, the protection of the Restricted TWT service period is not sufficient, and the following problems are not solved: the quiet interval protection method overlapping with the SP is not applied to some EHT STAs, how to restrict the channel access of R-TWT non-scheduled stations and non-R-TWT stations within the SP; how to ensure that R-TWT scheduled stations only send R-TWT low-latency service flows; for non-EHT STAs that do not support the Quiet Element, how to prevent the STA from competing for channels during the SP to obtain transmission opportunities.

[0085] Therefore, 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 sites that do not support R-TWT and / or the legacy sites (pre-EHT STA) that do 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).

[0086] The current IEEE 802.11 specification lacks an evaluation mechanism for the effectiveness of Restricted TWT operations in prioritizing the transmission of delay-sensitive traffic flows, which hinders stations that intend to transmit delay-sensitive traffic flows from selecting associated APs or links and specific restricted TWTs.

[0087] Based on the above issues, the present application proposes an evaluation mechanism for the transmission of delay-sensitive service flows during a delay-sensitive service service cycle. This mechanism facilitates non-AP stations to, after receiving this information provided by an AP, firstly, select an AP or link to be used for low-latency service flow transmission using an implementation-specific AP or link selection algorithm; secondly, for a specific AP or link, select a restricted TWT corresponding to a specific restricted TWT schedule (R-TWT schedule) established by the AP or link to be joined; and thirdly, for MLD devices, select a specific TID mapped to a specific link in the uplink and / or downlink direction during the flow identifier-to-link process.

[0088] 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.

[0089] FIG4 is a schematic flowchart of a wireless communication method 200 according to an embodiment of the present application. As shown in FIG4 , the wireless communication method 200 may include at least part of the following contents:

[0090] S210, the AP sends delay-sensitive service service period load information; wherein the delay-sensitive service service period load information includes at least channel utilization information during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, or the delay-sensitive service service period load information includes at least channel utilization information during the R-TWT service period corresponding to m R-TWT schedules established in the first BSS; wherein the number of all R-TWT schedules established in the first BSS is n, m and n are both positive integers, and m<n;

[0091] S220: The STA receives the service period load information of the delay-sensitive service.

[0092] It should be understood that FIG4 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 FIG4.

[0093] In an embodiment of the present application, the STA can obtain the channel utilization information during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS through the delay-sensitive service service period load information, or the STA can obtain the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS through the delay-sensitive service service period load information, so that the STA can perform subsequent transmission of the delay-sensitive service flow based on the obtained channel utilization information to optimize the delay-sensitive service flow transmission performance based on R-TWT.

[0094] In the embodiments of the present application, a "field" may also be referred to as a "domain" or a "subfield." A field may occupy one or more bytes (byte / octet), or a field may occupy one or more bits (bit). "Latency-sensitive services" may also be referred to as "low-latency services." This application does not limit this.

[0095] In some embodiments, the R-TWT scheduling described in the embodiments of the present application can be extended to delay-sensitive service scheduling, and the R-TWT service period can be extended to a delay-sensitive service service period. For example, the above S210 can be extended to: the delay-sensitive service service period load information at least includes the channel utilization information during the delay-sensitive service service period corresponding to all delay-sensitive service scheduling established in the first BSS, or the delay-sensitive service service period load information at least includes the channel utilization information during the delay-sensitive service service period corresponding to the m delay-sensitive service scheduling established in the first BSS; wherein, the number of all delay-sensitive service scheduling established in the first BSS is n, m and n are both positive integers, and m<n. The subsequent scheme is similar, R-TWT scheduling can also be extended to delay-sensitive service scheduling, and the R-TWT service period can also be extended to delay-sensitive service service period, which will not be repeated here.

[0096] In some embodiments, the AP corresponding to the delay-sensitive service service period load information may be the same as or different from the AP that sends the delay-sensitive service service period load information. For example, the AP corresponding to the delay-sensitive service service period load information may be the AP itself that sends the delay-sensitive service service period load information, or the AP corresponding to the delay-sensitive service service period load information may be a neighboring AP of the AP that sends the delay-sensitive service service period load information, or the AP corresponding to the delay-sensitive service service period load information may be another AP in the same co-located AP set as the AP that sends the delay-sensitive service service period load information, or the AP corresponding to the delay-sensitive service service period load information may be another AP in the same multiple Basic Service Set Identifier (BSSID) set as the AP that sends the delay-sensitive service service period load information.

[0097] For example, when the AP corresponding to the delay-sensitive service service cycle load information is different from the AP that sends the delay-sensitive service service cycle load information, the AP that sends the delay-sensitive service service cycle load information can obtain the delay-sensitive service service cycle load information or information related to the delay-sensitive service service cycle load information from the AP corresponding to the delay-sensitive service service cycle load information.

[0098] The embodiments of the present application can also be applied to multi-link devices (MLDs). For example, the above S210 can be replaced by: the AP MLD sends the delay-sensitive service period load information; and the above S220 can be replaced by: the non-AP MLD receives the delay-sensitive service period load information. Specifically, the non-AP MLD can perform subsequent transmission of the delay-sensitive service flow based on the obtained channel utilization information to optimize the transmission performance of the delay-sensitive service flow based on R-TWT.

[0099] In the embodiment of the present application, the AP is an AP that supports R-TWT operations, and the AP has established R-TWT membership.

[0100] In some embodiments, the first BSS may be any BSS corresponding to the AP, or the first BSS may be a specific BSS corresponding to the 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 AP, or the specific BSS is the BSS with the largest amount of delay-sensitive services among all BSSs corresponding to the AP, or the specific BSS is the BSS with the smallest identifier among all BSSs corresponding to the AP, or the specific BSS is the BSS with the largest identifier among all BSSs corresponding to the AP, or the specific BSS is any BSS associated with R-TWT among all BSSs corresponding to the 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 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 AP.

[0101] In some embodiments, when the delay-sensitive service service period load information includes at least channel utilization information during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, the delay-sensitive service service period load information may be information at the BSS granularity. When the delay-sensitive service service period load information includes at least channel utilization information during the R-TWT service period corresponding to m R-TWT schedules established in the first BSS, the delay-sensitive service service period load information may be information at the R-TWT scheduling granularity.

[0102] In some embodiments, the STA selects an AP and / or link for delay-sensitive service flow transmission based on the delay-sensitive service service period load information. Thus, the STA can select an AP and / or link that is more conducive to delay-sensitive service flow transmission.

[0103] 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 according to the R-TWT service cycle load 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 according to the R-TWT service cycle load information. That is, the STA can select the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP and to be joined, which is more conducive to the transmission of 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, which is more conducive to the transmission of delay-sensitive business flows.

[0104] In some embodiments, the target AP is configured or indicated by the 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.

[0105] In some embodiments, the target link is configured or indicated by the 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.

[0106] In some embodiments, the target R-TWT scheduling is configured or indicated by the AP, or the target R-TWT scheduling is determined by the STA.

[0107] In some embodiments, the non-AP MLD to which the STA belongs selects a link to which the target traffic identifier (TID) is mapped in the uplink and / or downlink direction during the traffic identifier-to-link mapping process based on the R-TWT service period load information. That is, the non-AP MLD can select a link to which the TID is mapped in the uplink and / or downlink direction that is more conducive to the transmission of delay-sensitive traffic flows during the traffic identifier-to-link mapping process.

[0108] In some embodiments, the target TID is configured or indicated by the AP, or the target TID is determined by the STA.

[0109] For example, STA selects the AP and / or link used for delay-sensitive service flow transmission based on the delay-sensitive service service cycle load information, and STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP and intended to join based on the R-TWT service cycle load information.

[0110] For example, STA selects the AP and / or link used for delay-sensitive service flow transmission based on the delay-sensitive service service cycle load information, and STA selects the broadcast TWT corresponding to the target R-TWT scheduling established on the target link to be joined based on the R-TWT service cycle load information.

[0111] For example, STA selects the AP and / or link used for delay-sensitive service flow transmission based on the delay-sensitive service service cycle load information, STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP and to be joined based on the R-TWT service cycle load information, and STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target link and to be joined based on the R-TWT service cycle load information.

[0112] For example, the STA selects the AP and / or link for delay-sensitive service flow transmission based on the delay-sensitive service service period load information, and the Non-AP MLD to which the STA belongs selects the link mapped to the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process based on the R-TWT service period load information.

[0113] For example, the STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP and intended to join according to the R-TWT service cycle load information, and the Non-AP MLD to which the STA belongs selects the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process based on the R-TWT service cycle load information.

[0114] For example, the STA selects the broadcast TWT corresponding to the target R-TWT scheduling established in the target link and to be joined according to the R-TWT service cycle load information, and the Non-AP MLD to which the STA belongs selects the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process based on the R-TWT service cycle load information.

[0115] For example, STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP and intended to join according to the R-TWT service cycle load information, STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target link and intended to join according to the R-TWT service cycle load information, and the Non-AP MLD to which the STA belongs selects the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process based on the R-TWT service cycle load information.

[0116] For example, the STA selects the AP and / or link for delay-sensitive service flow transmission based on the delay-sensitive service service cycle load 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 R-TWT service cycle load information, and the Non-AP MLD to which the STA belongs selects the link mapped to the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process based on the R-TWT service cycle load information.

[0117] For example, the STA selects the AP and / or link for delay-sensitive service flow transmission based on the delay-sensitive service service cycle load information, 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 R-TWT service cycle load information, and the Non-AP MLD to which the STA belongs selects the link mapped to the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process based on the R-TWT service cycle load information.

[0118] For example, STA selects the AP and / or link for delay-sensitive service flow transmission based on the delay-sensitive service service cycle load information, STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP and to be joined based on the R-TWT service cycle load information, STA selects the broadcast TWT corresponding to the target R-TWT scheduling established by the target link and to be joined based on the R-TWT service cycle load information, and the Non-AP MLD to which the STA belongs selects the link mapped to the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process based on the R-TWT service cycle load information.

[0119] In some embodiments, when the delay-sensitive service service period load information includes at least channel utilization information during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, the channel utilization information during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS includes, but is not limited to, at least one of the following:

[0120] The cumulative proportion of duration during the R-TWT service cycle corresponding to all R-TWT scheduling established in the first BSS, the transmission proportion of AP and R-TWT member STA during the R-TWT service cycle corresponding to all R-TWT scheduling established in the first BSS, the transmission efficiency of delay-sensitive service flows during the R-TWT service cycle corresponding to all R-TWT scheduling established in the first BSS, the transmission time proportion of delay-sensitive service flows during the R-TWT service cycle corresponding to all R-TWT scheduling established in the first BSS, and the interference time proportion excluding internal transmission of the first BSS during the R-TWT service cycle corresponding to all R-TWT scheduling established in the first BSS.

[0121] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS (for example, selecting an AP and / or link for delay-sensitive service flow transmission, for example, selecting a broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0122] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the transmission ratio of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the transmission ratio of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS (for example, selecting the AP and / or link for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to join, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to join, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0123] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS (for example, selecting the AP and / or link for transmission of delay-sensitive service flows, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0124] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the transmission time ratio of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of the delay-sensitive service flow based on the transmission time ratio of the delay-sensitive service during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS (for example, selecting the AP and / or link for the transmission of the delay-sensitive service flow, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of the delay-sensitive service based on R-TWT.

[0125] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the proportion of interference time during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, excluding the internal transmission of the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the proportion of interference time during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, excluding the internal transmission of the first BSS, to optimize the transmission performance of delay-sensitive services based on R-TWT (for example, selecting an AP and / or link for delay-sensitive service flow transmission, or selecting a broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, or selecting a broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, or selecting a link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0126] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the transmission proportion of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS and the transmission proportion of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS (for example, selecting the AP and / or link for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to join, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to join, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the delay-sensitive service transmission performance based on R-TWT.

[0127] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the transmission efficiency of delay-sensitive business flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS and the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS (for example, selecting APs and / or links for transmission of delay-sensitive service flows, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0128] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the proportion of the transmission time of delay-sensitive business flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS and the transmission time proportion of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS (for example, selecting the AP and / or link for the transmission of delay-sensitive service flows, or for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, or for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, or for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0129] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the proportion of interference time during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, excluding internal transmission of the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS and the proportion of interference time during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, excluding internal transmission within the first BSS, to optimize the transmission performance of delay-sensitive services based on R-TWT (for example, selecting the AP and / or link for delay-sensitive service flow transmission, or selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, or selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, or selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD).

[0130] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the transmission ratio of AP and R-TWT member STA during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows based on the transmission ratio of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS and the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS (for example, selecting the AP and / or link for the transmission of delay-sensitive service flows, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive service flows based on R-TWT.

[0131] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the transmission ratio of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the transmission time ratio of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows based on the transmission ratio of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS and the transmission time ratio of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS (for example, selecting the AP and / or link for the transmission of delay-sensitive service flows, and for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, and for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive service flows based on R-TWT.

[0132] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS includes: the transmission ratio of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, and the interference time ratio excluding the internal transmission of the first BSS during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows based on the transmission ratio of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS and the interference time ratio excluding the internal transmission of the first BSS during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, so as to optimize the transmission performance of delay-sensitive service flows based on R-TWT (for example, selecting the AP and / or link for delay-sensitive service flow transmission, and for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, and for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD).

[0133] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the transmission time ratio of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows based on the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS and the transmission time proportion of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS (for example, selecting APs and / or links for transmission of delay-sensitive service flows, for example, selecting broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting links mapped by the target TID in the uplink and / or downlink directions during the flow identifier to link mapping process of Non-AP MLD) to optimize the transmission performance of delay-sensitive service flows based on R-TWT.

[0134] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the transmission efficiency of delay-sensitive business flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the proportion of interference time other than internal transmission of the first BSS during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows based on the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS and the proportion of interference time excluding internal transmission of the first BSS during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, so as to optimize the transmission performance of delay-sensitive service flows based on R-TWT (for example, selecting the AP and / or link used for transmission of delay-sensitive service flows, and for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, and for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD).

[0135] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the transmission time ratio of delay-sensitive business flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the interference time ratio other than the internal transmission of the first BSS during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows based on the transmission time proportion of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS and the interference time proportion during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, except for the internal transmission of the first BSS, so as to optimize the transmission performance of delay-sensitive service flows based on R-TWT (for example, selecting the AP and / or link for transmission of delay-sensitive service flows, and for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, and for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of Non-AP MLD).

[0136] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the transmission time proportion of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows based on the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, and the transmission time proportion of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, so as to optimize the transmission performance of delay-sensitive service flows based on R-TWT (for example, selecting the AP and / or link for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD).

[0137] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the transmission ratio of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the transmission time ratio of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link, for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) based on the transmission ratio of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the transmission time ratio of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, so as to optimize the transmission performance of delay-sensitive service flows based on R-TWT.

[0138] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission time proportion of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the interference time proportion other than internal transmission of the first BSS during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows based on the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, the transmission time proportion of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, and the interference time proportion other than the internal transmission of the first BSS during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, so as to optimize the transmission performance of delay-sensitive service flows based on R-TWT (for example, selecting the AP and / or link for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD).

[0139] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission proportion of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the transmission time proportion of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to join, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to join, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) based on the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission proportion of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, so as to optimize the transmission performance of delay-sensitive service flows based on R-TWT.

[0140] For example, the channel utilization information during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission proportion of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission time proportion of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the interference time proportion excluding the internal transmission of the first BSS during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS. Thus, the STA can perform subsequent transmission of delay-sensitive service flows based on the cumulative proportion of the duration during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission proportion of the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, the transmission time proportion of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS, and the interference time proportion excluding the internal transmission of the first BSS during the R-TWT service period corresponding to all R-TWT scheduling established in the first BSS (for example, selecting the AP and / or link for the transmission of the delay-sensitive service flow, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to join, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to join, for example, Non-AP MLD selects the link to which the target TID is mapped in the uplink and / or downlink direction during the flow identifier to link mapping process to optimize the transmission performance of delay-sensitive service flows based on R-TWT.

Specifically, the STA can obtain the number of EHTSTAs that currently support R-TWT in the first BSS, and in the subsequent transmission process for delay-sensitive services, give priority to channel access of EHTSTAs that support R-TWT during the R-TWT service period, and give priority to EHTSTAs that support R-TWT to transmit delay-sensitive services, thereby optimizing the transmission of delay-sensitive service flows.

[0146] For example, the delay-sensitive service service period load information also includes: the number of EHT STAs that currently do not support R-TWT in the first BSS. Specifically, the STA can obtain the number of EHT STAs that currently do not support R-TWT in the first BSS, and in the subsequent transmission process for delay-sensitive services, restrict the channel access of EHT STAs that do not support R-TWT during the R-TWT service period, thereby optimizing the transmission of delay-sensitive service flows.

[0147] For example, the delay-sensitive service service period load information also includes: the number of legacy STAs in the first BSS that support quiet intervals. Specifically, the STA can obtain the number of legacy STAs in the first BSS that currently support quiet intervals. In the subsequent transmission process for delay-sensitive services, legacy STAs that support quiet intervals are given priority in obtaining transmission opportunities during the R-TWT service period, and legacy STAs that support quiet intervals are given priority in transmitting delay-sensitive services, thereby optimizing the transmission of delay-sensitive service flows.

[0148] For example, the delay-sensitive service service period load information also includes the number of legacy STAs in the first BSS that do not support quiet intervals. Specifically, the STA can obtain the number of legacy STAs in the first BSS that do not currently support quiet intervals. In subsequent transmissions of delay-sensitive services, legacy STAs that do not support quiet intervals are prevented from obtaining transmission opportunities during the R-TWT service period, thereby optimizing the transmission of delay-sensitive service flows.

[0149] For example, the delay-sensitive service service period load information also includes: the available resource capability information of all R-TWT schedules established in the first BSS. Specifically, the available resource capability information of all R-TWT schedules established in the first BSS may be the amount of remaining medium time available for the addition of new member sites corresponding to the R-TWT service period during the R-TWT service period corresponding to all R-TWT schedules during the measurement duration. This helps the STA select an AP that may accept future R-TWT membership establishment requests.

[0150] For example, the delay-sensitive service service period load information also includes: the available resource capability information of all R-TWT schedulings that can be established in the first BSS. Specifically, the available resource capability information of all R-TWT schedulings established in the first BSS can be the remaining medium time currently available for the R-TWT service period corresponding to the newly established restricted TWT scheduling during the measurement duration. It helps STA select APs that may accept future R-TWT membership establishment requests.

[0151] For example, the delay-sensitive service service period load information also includes: the available resource capability information of the R-TWT scheduling in the first BSS. Specifically, the available resource capability information of all R-TWT scheduling established in the first BSS can be the remaining medium time currently available for the R-TWT service period corresponding to the restricted TWT scheduling during the measurement duration, including the remaining medium time available for all established R-TWT scheduling (R-TWT schedule) and the remaining medium time available for the R-TWT service period corresponding to the newly established restricted TWT scheduling.

[0187] Specifically, the BSS R-TWT service period load element contains the number of EHT sites that currently support or do not support R-TWT in the first BSS, the number of legacy sites that support or do not support the quiet interval, and the channel utilization during the R-TWT service period corresponding to the restricted TWT scheduling, as well as information on the available resource capabilities of the R-TWT scheduling (R-TWT schedule). The format of the BSS R-TWT service period load element can be shown in Figure 5. The site receiving the BSS R-TWT service period load element can use the information it conveys to, first, select the AP or link to be used for low-latency service flow transmission in the implementation-specific AP or link selection algorithm; second, for a specific AP or link, select the R-TWT corresponding to the specific R-TWT schedule (R-TWT schedule) that the AP or link has established and intends to join; third, for MLD devices, select the mapping of a specific TID to a specific link in the uplink and / or downlink direction during the flow identifier to link process.

[0191] Specifically, in the BSS R-TWT service cycle load element shown in Figure 5, the additional parameter presence bitmap field contains a bitmap, and if the BSS R-TWT service cycle load element contains the i-th field starting from the "cumulative proportion of duration of all current R-TWT service cycles field", the i-th item of the bitmap is set to 1. For each field starting from the "cumulative proportion of duration of all current R-TWT service cycles field", the value 0 is reserved.

[0192] Specifically, in the BSS R-TWT Service Period Load element shown in Figure 5, the Number of EHT STAs Supporting R-TWT field indicates the number of EHT stations currently associated with the BSS where the R-TWT schedule is located and that support R-TWT. EHT STAs declare that they are EHT stations by transmitting their EHT Capability elements and setting dot11RestrictedTWTOptionImplemented to true to indicate support for R-TWT.

[0193] Specifically, in the BSS R-TWT service period load element shown in Figure 5, the number of EHT sites that do not support R-TWT field indicates the number of EHT sites currently associated with the BSS where the restricted TWT schedule (R-TWT schedule) is located and that do not support R-TWT. Among them, EHT sites declare that they are EHT sites by transmitting their EHT capability elements and setting dot11RestrictedTWTOptionImplemented to false to indicate that they do not support R-TWT.

[0194] Specifically, in the BSS R-TWT service cycle load element shown in Figure 5, the number of legacy sites supporting quiet interval (quiet interval) field indicates the number of legacy sites (i.e., sites before EHT, such as high-efficiency (HE), very high throughput (VHT), high throughput (HT), and non-HT (non-HT) sites) that are currently associated with the BSS where the restricted TWT schedule (R-TWT schedule) is located and support quiet interval (quiet interval).

[0195] Specifically, in the BSS R-TWT service cycle load element shown in Figure 5, the number of legacy sites that do not support quiet intervals field indicates the number of legacy sites (i.e., sites before EHT, such as HE, VHT, HT, and non-HT sites) that are currently associated with the BSS where the restricted TWT schedule (R-TWT schedule) is located and do not support quiet intervals.

[0196] In some embodiments, the cumulative proportion of the duration during the R-TWT service cycle corresponding to all R-TWT schedules established in the first BSS is determined based on at least one of the following: the cumulative duration during all current R-TWT service cycles, the measurement duration corresponding to the first BSS, the number of consecutive beacon intervals used to measure the R-TWT service cycle duration and channel application conditions, and the duration used by the STA to schedule beacon transmission.

[0197] For example, the cumulative proportion of the duration during the R-TWT service cycle corresponding to all R-TWT schedules established in the first BSS is determined based on the cumulative duration during all current R-TWT service cycles and the measurement duration corresponding to the first BSS.

[0198] For example, the cumulative proportion of the R-TWT service cycle duration corresponding to all R-TWT schedules established in the first BSS is determined based on the cumulative duration of all current R-TWT service cycle periods, the number of consecutive beacon intervals used to measure the R-TWT service cycle duration and channel application conditions, and the duration used by STA to schedule beacon transmission.

[0199] In some embodiments, the cumulative proportion of the duration of the R-TWT service period corresponding to all R-TWT schedules established in the first BSS is determined based on the following formula 1:

[0200] in, represents the duration of the R-TWT service period corresponding to the i-th R-TWT schedule among all R-TWT schedules established in the first BSS, It represents the cumulative duration (such as microseconds) of the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, dot11ChannelUtilizationBeaconsIntervals represents the number of consecutive beacon intervals used to measure the duration of the R-TWT service period and the channel application, dot11BeaconPeriod represents the duration (in TU) used by the STA to schedule beacon transmission, and the time proportion can be represented by a linear ratio of 255, where 255 represents 100%.

[0201] In some embodiments, the transmission ratio between the AP and the R-TWT member STA during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS is determined based on at least one of the following: all medium busy times caused by transmissions between the AP and the R-TWT member STAs, and the cumulative duration of all current R-TWT service periods.

[0202] In some embodiments, the transmission ratio of the AP and the R-TWT member STAs during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS is determined based on the following formula 2:

[0203] in, Indicates the medium busy time caused by all transmissions between the AP and R-TWT member STAs. represents the duration of the R-TWT service period corresponding to the i-th R-TWT schedule among all R-TWT schedules established in the first BSS, It represents the cumulative duration of the R-TWT service period corresponding to all R-TWT schedules established in the first BSS. The time proportion can be expressed by a linear ratio of 255, where 255 represents 100%.

[0204] For example, in Formula 2, the transmission ratio domain between the AP and the member sites during all current R-TWT service cycles is used to define the time ratio of the medium busyness caused by the transmission between the AP and the member sites corresponding to the restricted TWT schedule monitored by the AP during the R-TWT service cycle duration corresponding to all current established R-TWT schedules (R-TWT Schedule) during the measurement duration, where the medium busyness can be indicated by the physical carrier sensing (CS) mechanism, and the time ratio can be represented by a linear ratio of 255 (255 represents 100%).

[0205] In some embodiments, the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS is determined based on at least one of the following: all medium busy times caused by the transmission of delay-sensitive service flows between the AP and the R-TWT member STAs, and the transmission time of delay-sensitive service flows pre-scheduled during all current R-TWT service periods.

[0206] In some embodiments, the transmission efficiency of the delay-sensitive traffic flow during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS is determined based on the following formula 3:

[0207] in, Indicates the medium busy time caused by the transmission of delay-sensitive service flows between the AP and R-TWT member STAs. represents the pre-scheduled delay-sensitive service flow transmission time during the R-TWT service period corresponding to the i-th R-TWT schedule among all R-TWT schedules established in the first BSS, It represents the transmission time of delay-sensitive service flows pre-scheduled during all R-TWT service cycles. The time proportion can be expressed by a linear ratio of 255, where 255 represents 100%.

[0208] For example, in Formula 3, the pre-scheduled delay-sensitive service flow transmission time during all R-TWT service periods is used to define the pre-scheduled delay-sensitive service flow transmission time between the AP and the member STAs during the measurement duration and during the R-TWT service period duration corresponding to all currently established R-TWT schedules (R-TWT Schedule). For the R-TWT service period corresponding to each established R-TWT schedule (R-TWT Schedule), it can be based on the uplink and / or downlink delay-sensitive service flow requirements between the AP and the member STA, and according to the supported transmission bandwidth and rate, modulation and coding scheme (MCS), number of spatial streams (NSS) and other transmission parameters between the AP and the member STAs. The uplink and / or downlink delay-sensitive service flow requirements between the AP and the member STAs may be determined by using a stream classification service (SCS) to determine the characteristics of the to-be-transmitted flow and QoS information in a Quality of Service (QoS) characteristics element carried when establishing an SCS flow (if any) corresponding to the delay-sensitive service flow, and / or based on traffic conditions related to the buffer delay-sensitive service flow reported by the station, such as a Buffer Status Report (BSR).

[0209] In some embodiments, the transmission time proportion of delay-sensitive service flows during the R-TWT service cycle corresponding to all R-TWT schedules established in the first BSS is determined based on at least one of the following: the transmission time of delay-sensitive service flows pre-scheduled during all R-TWT service cycles, and the cumulative duration during all current R-TWT service cycles.

[0210] In some embodiments, the transmission time proportion of the delay-sensitive service flow during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS is determined based on the following formula 4:

[0211] in, represents the pre-scheduled delay-sensitive service flow transmission time during the R-TWT service period corresponding to the i-th R-TWT schedule among all R-TWT schedules established in the first BSS, Indicates the transmission time of delay-sensitive service flows pre-scheduled during all R-TWT service periods, represents the duration of the R-TWT service period corresponding to the i-th R-TWT schedule among all R-TWT schedules established in the first BSS, It represents the cumulative duration of the R-TWT service period corresponding to all R-TWT schedules established in the first BSS. The time proportion can be expressed by a linear ratio of 255, where 255 represents 100%.

[0212] For example, in Formula 4, the time proportion of delay-sensitive service flow transmissions pre-scheduled during all R-TWT service periods is used to define the percentage of time occupied by delay-sensitive service flow transmissions pre-scheduled during all R-TWT service periods during the R-TWT service period corresponding to the restricted TWT scheduling currently established in the BSS during the measurement duration, where the time proportion can be expressed by a linear ratio of 255 (255 represents 100%).

[0213] In some embodiments, the proportion of interference time during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, excluding internal transmissions within the first BSS, is determined based on at least one of the following: channel busy time during all R-TWT service periods, medium busy time caused by transmissions between the AP and associated STAs, and the cumulative duration of all current R-TWT service periods.

[0214] For example, the proportion of interference time during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, except for transmission within the first BSS, is determined based on the channel busy time during all R-TWT service periods and the medium busy time caused by transmission between the AP and associated STAs.

[0215] For example, the proportion of interference time during the R-TWT service cycle corresponding to all R-TWT schedules established in the first BSS, except for the internal transmission of the first BSS, is determined based on the channel busy time during all R-TWT service cycles and the cumulative duration of all current R-TWT service cycles.

[0216] For example, the proportion of interference time during the R-TWT service cycle corresponding to all R-TWT schedules established in the first BSS, excluding the internal transmission of the first BSS, is determined based on the channel busy time during all R-TWT service cycles, the medium busy time caused by the transmission between the AP and the associated STAs, and the cumulative duration of all current R-TWT service cycles.

[0217] In some embodiments, the proportion of interference time during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS, excluding the first BSS internal transmission, is determined based on the following formula 5:

[0218] in, represents the pre-scheduled delay-sensitive service flow transmission time during the R-TWT service period corresponding to the i-th R-TWT schedule among all R-TWT schedules established in the first BSS, Indicates the transmission time of delay-sensitive service flows pre-scheduled during all R-TWT service periods, Indicates the medium busy time caused by transmission between the AP and the associated STAs. represents the duration of the R-TWT service period corresponding to the i-th R-TWT schedule among all R-TWT schedules established in the first BSS, It represents the cumulative duration of the R-TWT service period corresponding to all R-TWT schedules established in the first BSS. The time proportion can be expressed by a linear ratio of 255, where 255 represents 100%.

[0219] For example, in Formula 5, the interference time proportion field outside BSS internal transmission during all R-TWT service periods is used to define the percentage of time occupied by interference other than BSS internal transmission (such as overlapping Basic Service Set (OBSS) interference) during the R-TWT service period corresponding to the restricted TWT scheduling currently established in the BSS, where the time proportion can be expressed by a linear ratio of 255 (255 represents 100%).

[0220] Among them, the channel busy time during all R-TWT service periods is defined as the time during which the medium is busy as monitored by the AP during the R-TWT service periods corresponding to all R-TWT schedules during the measurement duration, wherein the medium is busy as monitored by the AP as indicated by the physical or virtual carrier sensing (CS) mechanism. The cumulative duration of all current R-TWT service periods is defined as the cumulative number of microseconds of the R-TWT service period duration corresponding to all currently established R-TWT schedules (R-TWT Schedule) during the measurement duration.

[0221] The medium busy time caused by transmission between the AP and the associated sites is defined as the time of medium busyness caused by transmission between the AP and the associated sites monitored by the AP during the R-TWT service period corresponding to all restricted TWT scheduling during the measurement duration, where the medium busyness can be indicated by the physical carrier sensing (CS) mechanism.

[0222] Specifically, in the BSS R-TWT service period load element shown in Figure 5, the available resource capability field of all established R-TWT schedules is used to define the amount of remaining medium time available for the addition of new member sites corresponding to the R-TWT service period during the R-TWT service period corresponding to all restricted TWT schedules during the measurement duration. The available resource capability field of all currently established R-TWT schedules (R-TWT schedule) contains an unsigned integer in units of 32us / s. This field helps the STA select APs that may accept future R-TWT membership establishment requests, but it does not represent a guarantee that the AP will accept these requests.

[0223] Specifically, in the BSS R-TWT service period load element shown in Figure 5, the available resource capability field for the R-TWT schedule to be established is used to define the remaining medium time currently available for the R-TWT service period corresponding to the newly established restricted TWT schedule during the measurement duration. The available resource capability field for the R-TWT schedule to be established (R-TWT schedule) contains an unsigned integer with a unit of 32us / s. This field helps the STA select the AP that may accept future R-TWT membership establishment requests, but it does not represent a guarantee that the AP will accept these requests.

[0224] Specifically, in the BSS R-TWT service period load element shown in Figure 5, the available resource capability field of the R-TWT schedule is used to define the remaining medium time currently available for the R-TWT service period corresponding to the restricted TWT schedule during the measurement duration, including the remaining medium time available for all established R-TWT schedules (R-TWT schedule) and the remaining medium time available for the R-TWT service period corresponding to the newly established restricted TWT schedule. The available resource capability field of the R-TWT schedule (R-TWT schedule) contains an unsigned integer in units of 32us / s. This field helps the STA select an AP that may accept future R-TWT membership establishment requests, but it does not represent a guarantee that the AP will accept these requests.

[0225] In some embodiments, when the delay-sensitive service service period load information includes at least channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes, but is not limited to, at least one of the following:

[0226] The cumulative proportion of the duration of the R-TWT service period corresponding to each R-TWT scheduling in the m R-TWT scheduling, the proportion of the transmission time of the pre-scheduled delay-sensitive service flow during the R-TWT service period corresponding to each R-TWT scheduling in the m R-TWT scheduling, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to each R-TWT scheduling in the m R-TWT scheduling, the proportion of the medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each R-TWT scheduling in the m R-TWT scheduling, the R-TWT service period utilization based on the transmission of the R-TWT member STA during the R-TWT service period corresponding to each R-TWT scheduling in the m R-TWT scheduling, and the R-TWT service period utilization based on the transmission of the delay-sensitive service flow during the R-TWT service period corresponding to each R-TWT scheduling in the m R-TWT scheduling. rate, the underutilization rate of the R-TWT service period based on non-R-TWT member STA transmission during the R-TWT service period corresponding to each of the m R-TWT schedules, the underutilization rate of the R-TWT service period based on non-delay sensitive business flow transmission during the R-TWT service period corresponding to each of the m R-TWT schedules, the channel utilization ratio during the R-TWT service period corresponding to each of the m R-TWT schedules, the channel utilization ratio based on R-TWT member STA transmission during the R-TWT service period corresponding to each of the m R-TWT schedules, the channel utilization ratio based on delay sensitive business flow transmission during the R-TWT service period corresponding to each of the m R-TWT schedules, and the channel idle ratio during the R-TWT service period corresponding to each of the m R-TWT schedules.

[0227] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the cumulative proportion of the duration during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules (for example, selecting an AP and / or link for delay-sensitive service flow transmission, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0228] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the proportion of the transmission time of the delay-sensitive service flow pre-scheduled during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the proportion of the transmission time of the delay-sensitive service flow pre-scheduled during the R-TWT service period corresponding to each of the m R-TWT schedules (for example, selecting an AP and / or link for delay-sensitive service flow transmission, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0229] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules (for example, selecting an AP and / or link for transmission of delay-sensitive service flows, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting a link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0230] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the proportion of medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the proportion of medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules (for example, selecting an AP and / or link for delay-sensitive service flow transmission, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be added, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be added, and for example, selecting a link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0231] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the R-TWT service period utilization rate based on the R-TWT member STA transmission during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the R-TWT service period utilization rate based on the R-TWT member STA transmission during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules (for example, selecting an AP and / or link for delay-sensitive service flow transmission, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting a link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0232] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the R-TWT service period utilization rate based on the transmission of delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the R-TWT service period utilization rate based on the transmission of delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules (for example, selecting an AP and / or link for transmission of delay-sensitive service flows, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting a link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0233] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the underutilization rate of the R-TWT service period based on the transmission of non-R-TWT member STAs during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the underutilization rate of the R-TWT service period based on the transmission of non-R-TWT member STAs during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules (for example, selecting an AP and / or link for delay-sensitive service flow transmission, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting a link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process by the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0234] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the R-TWT service period underutilization rate based on the transmission of non-delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the R-TWT service period underutilization rate based on the transmission of non-delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules (for example, selecting an AP and / or link for transmission of delay-sensitive service flows, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting a link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process by the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0235] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the channel utilization ratio during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the channel utilization ratio during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules (for example, selecting an AP and / or link for delay-sensitive service flow transmission, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0236] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the channel utilization ratio based on the transmission of the R-TWT member STA during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the channel utilization ratio based on the transmission of the R-TWT member STA during the R-TWT service period corresponding to each R-TWT schedule in the m R-TWT schedules (for example, selecting the AP and / or link for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0237] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the channel utilization ratio based on the transmission of delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the channel utilization ratio based on the transmission of delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules (for example, selecting an AP and / or link for transmission of delay-sensitive service flows, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting a link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0238] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the channel idle ratio during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, the STA can perform subsequent transmission of delay-sensitive services based on the channel idle ratio during the R-TWT service period corresponding to each of the m R-TWT schedules (for example, selecting an AP and / or link for delay-sensitive service flow transmission, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target AP to be joined, for example, selecting a broadcast TWT corresponding to the target R-TWT schedule established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of the Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0239] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the transmission time of the pre-scheduled delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, and the proportion of the medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, subsequent transmission of delay-sensitive services can be performed based on the acquired channel utilization information (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0240] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the cumulative proportion of the duration of the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the transmission time of the pre-scheduled delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each of the m R-TWT schedules, and the R-TWT service period utilization based on the transmission of the R-TWT member STA during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, subsequent transmission of delay-sensitive services can be performed based on the acquired channel utilization information (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0241] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the cumulative proportion of the duration of the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the transmission time of the pre-scheduled delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each of the m R-TWT schedules, and the R-TWT service period utilization based on the transmission of delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, subsequent transmission of delay-sensitive services can be performed based on the acquired channel utilization information (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0242] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the cumulative proportion of the duration of the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the transmission time of the pre-scheduled delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each of the m R-TWT schedules, and the underutilization rate of the R-TWT service period based on transmission by non-R-TWT member STAs during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, subsequent transmission of delay-sensitive services can be performed based on the acquired channel utilization information (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0243] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the cumulative proportion of the duration of the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the transmission time of the pre-scheduled delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each of the m R-TWT schedules, and the underutilization rate of the R-TWT service period based on the transmission of non-delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, subsequent transmission of delay-sensitive services can be performed based on the acquired channel utilization information (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0244] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of transmission time of pre-scheduled delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules, the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each of the m R-TWT schedules, and the channel utilization proportion during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, subsequent transmission of delay-sensitive services can be performed based on the acquired channel utilization information (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0245] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the cumulative proportion of the duration during the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of transmission time of pre-scheduled delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules, the transmission efficiency of delay-sensitive service flows during the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each of the m R-TWT schedules, and the proportion of channel utilization based on transmission of R-TWT member STAs during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, subsequent transmission of delay-sensitive services can be performed based on the acquired channel utilization information (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

The proportion of medium busy time caused by interference, the utilization rate of the R-TWT service period based on the transmission of the R-TWT member STA during the R-TWT service period corresponding to each R-TWT scheduling in the m R-TWT scheduling, the underutilization rate of the R-TWT service period based on the transmission of non-R-TWT member STA during the R-TWT service period corresponding to each R-TWT scheduling in the m R-TWT scheduling, the proportion of channel utilization based on the transmission of R-TWT member STA during the R-TWT service period corresponding to each R-TWT scheduling in the m R-TWT scheduling, and the proportion of channel idleness during the R-TWT service period corresponding to each R-TWT scheduling in the m R-TWT scheduling.

The proportion of medium busy time caused by interference outside the internal transmission of the first BSS during the corresponding R-TWT service cycle, the R-TWT service cycle utilization rate based on delay-sensitive business flow transmission during the R-TWT service cycle corresponding to each R-TWT scheduling of the m R-TWT scheduling, the R-TWT service cycle underutilization rate based on non-delay-sensitive business flow transmission during the R-TWT service cycle corresponding to each R-TWT scheduling of the m R-TWT scheduling, and the channel utilization ratio based on delay-sensitive business flow transmission during the R-TWT service cycle corresponding to each R-TWT scheduling of the m R-TWT scheduling. Thus, subsequent transmission of delay-sensitive services can be performed based on the acquired channel utilization information (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0250] For example, the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS includes: the cumulative proportion of the duration of the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the transmission time of the pre-scheduled delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the transmission efficiency of the delay-sensitive service flow during the R-TWT service period corresponding to each of the m R-TWT schedules, the proportion of the medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to each of the m R-TWT schedules, the R-TWT service period utilization based on the transmission of the R-TWT member STA during the R-TWT service period corresponding to each of the m R-TWT schedules, and the R-TWT service period corresponding to each of the m R-TWT schedules. The utilization rate of the R-TWT service period based on the transmission of delay-sensitive business flows during the period, the underutilization rate of the R-TWT service period based on the transmission of non-R-TWT member STAs during the R-TWT service period corresponding to each of the m R-TWT schedules, the underutilization rate of the R-TWT service period based on the transmission of non-delay-sensitive business flows during the R-TWT service period corresponding to each of the m R-TWT schedules, the channel utilization ratio during the R-TWT service period corresponding to each of the m R-TWT schedules, the channel utilization ratio based on the transmission of R-TWT member STAs during the R-TWT service period corresponding to each of the m R-TWT schedules, the channel utilization ratio based on the transmission of delay-sensitive business flows during the R-TWT service period corresponding to each of the m R-TWT schedules, and the channel idle ratio during the R-TWT service period corresponding to each of the m R-TWT schedules. Thus, subsequent transmission of delay-sensitive services can be performed based on the acquired channel utilization information (for example, selecting APs and / or links for delay-sensitive service flow transmission, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target AP to be joined, for example, selecting the broadcast TWT corresponding to the target R-TWT scheduling established by the target link to be joined, and for example, selecting the link mapped by the target TID in the uplink and / or downlink direction during the flow identifier to link mapping process of Non-AP MLD) to optimize the transmission performance of delay-sensitive services based on R-TWT.

[0314] For example, the R-TWT service cycle load existence field occupies 1 bit; wherein the value 0 indicates that the R-TWT service cycle load field exists in the second element (i.e., the R-TWT element), and the value 1 indicates that the R-TWT service cycle load field does not exist in the second element (i.e., the R-TWT element); or, the value 1 indicates that the R-TWT service cycle load field exists in the second element (i.e., the R-TWT element), and the value 0 indicates that the R-TWT service cycle load field does not exist in the second element (i.e., the R-TWT element).

[0315] For example, the R-TWT element can be as shown in Figure 12, wherein the R-TWT traffic information field (occupies 0 or 3 bytes, that is, the field is an optional field) and the R-TWT service period load field (the number of occupied fields is variable). Specifically, a "Restricted TWT service period load field" is added to the TWT element, and a "Restricted TWT service period load" field is added to the Restricted TWT Parameter Set field of the restricted TWT element.

[0316] In some embodiments, the R-TWT service period payload presence field is located in the broadcast TWT information field in the second element.

[0317] In some embodiments, the R-TWT service period load 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 second element, the at least one bit in the broadcast TWT information field corresponds only to the R-TWT service period load existence field.

[0318] For example, the broadcast TWT information field can be as shown in Figure 13. Specifically, the "Restricted TWT Traffic Info Present" subfield in the broadcast TWT information subfield (Broadcast TWT Info subfield) of the R-TWT element is updated to the "R-TWT Traffic Information Present (Restricted TWT Traffic Info Present) / R-TWT Service Period Load Present" subfield. When the R-TWT cycle information is announced through a management frame, that is, when the negotiation type subfield (Negotiation Type subfield) of the TWT element is set to 2, the restricted TWT parameter set field (Restricted TWT Parameter Set field) of the restricted TWT element does not include the restricted TWT traffic information field. At the same time, the "Restricted TWT Traffic Info Present (Restricted TWT Traffic Info Present) / Restricted TWT Service Period Load Present" field of the broadcast TWT information field is indicated as the "Restricted TWT Service Period Load Present" field. When the value of the "Restricted TWT service cycle load exists" field is 1, it indicates that the restricted TWT parameter set field of the restricted TWT element contains the restricted TWT service cycle load (Restricted TWT load) field; when the value of the "Restricted TWT service cycle load exists" field is 0, it indicates that the restricted TWT parameter set field of the restricted TWT element does not contain the restricted TWT service cycle load (Restricted TWT load) field.

[0319] In some embodiments, the second frame is one of the following: a beacon frame, a probe response frame, an association response frame, and a reassociation response frame. Of course, the second frame may also be other frames, which is not limited in the embodiments of the present application.

[0320] In some embodiments, the cumulative proportion of the duration during the R-TWT service cycle corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on at least one of the following: the cumulative duration during the R-TWT service cycle corresponding to the j-th R-TWT schedule, the measurement duration corresponding to the j-th R-TWT schedule, the number of consecutive beacon intervals used to measure the R-TWT service cycle duration and channel utilization, and the duration used by the STA to schedule beacon transmission;

[0321] Wherein, j is a positive integer and j≤m.

[0322] For example, the cumulative proportion of the duration during the R-TWT service cycle corresponding to the j-th R-TWT scheduling among m R-TWT scheduling is determined based on the cumulative duration during the R-TWT service cycle corresponding to the j-th R-TWT scheduling and the measurement duration corresponding to the j-th R-TWT scheduling.

[0323] For example, the cumulative proportion of the duration during the R-TWT service cycle corresponding to the j-th R-TWT scheduling among m R-TWT scheduling is determined based on the cumulative duration during the R-TWT service cycle corresponding to the j-th R-TWT scheduling, the number of consecutive beacon intervals used to measure the R-TWT service cycle duration and channel application, and the duration used by STA to schedule beacon transmission.

[0324] In some embodiments, the cumulative proportion of the duration during the R-TWT service period corresponding to the jth R-TWT schedule among the m R-TWT schedules is determined based on the following formula 6:

[0325] in, represents the duration of the i-th service period in the R-TWT corresponding to the j-th R-TWT scheduling (e.g., in microseconds), It represents the cumulative duration of the R-TWT service cycle corresponding to the j-th R-TWT scheduling (such as in microseconds), s represents the number of service cycles in the R-TWT corresponding to the j-th R-TWT scheduling, s is a positive integer, dot11ChannelUtjljzatjonBeaconsJnterval represents the number of consecutive beacon intervals used to measure the duration of the R-TWT service cycle and the channel application, dot11BeaconPerjod represents the duration of the STA for scheduling beacon transmission (such as in TU), and the time proportion can be expressed by a linear ratio of 255, where 255 represents 100%.

[0326] In some embodiments, the proportion of the delay-sensitive service flow transmission time pre-scheduled during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on at least one of the following: the delay-sensitive service flow transmission time pre-scheduled during the R-TWT service period corresponding to the j-th R-TWT schedule, and the total duration of the R-TWT service period given during the R-TWT service period corresponding to the j-th R-TWT schedule;

[0327] Wherein, j is a positive integer and j≤m.

[0328] In some embodiments, the proportion of the pre-scheduled delay-sensitive service flow transmission time during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on the following formula 7:

[0329] in, represents the pre-scheduled delay-sensitive service flow transmission time during the i-th service period in the R-TWT corresponding to the j-th R-TWT scheduling, represents the pre-scheduled delay-sensitive service flow transmission time during the R-TWT service period corresponding to the j-th R-TWT scheduling, represents the duration of the i-th service period in the R-TWT corresponding to the j-th R-TWT scheduling, It represents the cumulative duration of the R-TWT service period corresponding to the j-th R-TWT scheduling, s represents the number of service periods in the R-TWT corresponding to the j-th R-TWT scheduling, s is a positive integer, and the time proportion can be represented by a linear ratio of 255, where 255 represents 100%.

[0330] For example, the transmission time of the delay-sensitive service flow pre-scheduled during the R-TWT service period refers to the transmission time of the delay-sensitive service flow pre-scheduled between the AP and the member STA during the R-TWT service period corresponding to the R-TWT scheduling, which can be determined based on the uplink and / or downlink delay-sensitive service flow requirements between the AP and the member STA, and according to the supported transmission bandwidth and rate, MCS, NSS and other transmission parameters between the AP and the member STA. Among them, the uplink and / or downlink delay-sensitive service flow requirements between the AP and the member STA can be determined by the QoS characteristics element (QoS Characteristics element) of the SCS flow (if any) corresponding to the delay-sensitive service flow when the SCS is established, and / or, based on the traffic conditions related to the buffer delay-sensitive service flow reported by the site, such as the buffer status report (BSR).

[0331] In some embodiments, the proportion of medium busy time caused by interference outside the internal transmission of the first BSS during the R-TWT service period corresponding to the j-th R-TWT scheduling among the m R-TWT scheduling is determined based on at least one of the following: the channel busy time during the R-TWT service period corresponding to the j-th R-TWT scheduling, the medium busy time caused by transmission between the AP and the R-TWT member STA during the R-TWT service period corresponding to the j-th R-TWT scheduling, the medium busy time caused by transmission between the AP and non-R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT scheduling, and the total duration of the R-TWT service period given during the R-TWT service period corresponding to the j-th R-TWT scheduling;

[0332] Wherein, j is a positive integer and j≤m.

[0333] In some embodiments, the proportion of medium busy time caused by interference outside the first BSS internal transmission during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on the following formula 8:

[0334] in, represents the channel busy time during the i-th service period in the R-TWT corresponding to the j-th R-TWT scheduling, represents the channel busy time during the R-TWT service period corresponding to the j-th R-TWT scheduling, represents the medium busy time caused by transmission between the AP and the R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT scheduling, represents the medium busy time caused by transmission between the AP and non-R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT scheduling, represents the duration of the i-th service period in the R-TWT corresponding to the j-th R-TWT scheduling, It represents the cumulative duration of the R-TWT service period corresponding to the j-th R-TWT scheduling, s represents the number of service periods in the R-TWT corresponding to the j-th R-TWT scheduling, s is a positive integer, and the time proportion can be represented by a linear ratio of 255, where 255 represents 100%.

[0335] For example, the interference time outside the BSS transmission (such as OBSS interference) during the R-TWT service period refers to the time during the R-TWT service period when the medium is busy due to interference outside the BSS transmission (such as OBSS interference), wherein the medium is busy as monitored by the AP through the physical or virtual carrier sensing (CS) mechanism.

[0336] In some embodiments, the transmission efficiency of the delay-sensitive traffic flow during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on at least one of the following: the medium busy time caused by the transmission of the delay-sensitive traffic flow between the AP and the R-TWT member STA during the R-TWT service period corresponding to the j-th R-TWT schedule, and the pre-scheduled delay-sensitive traffic flow transmission time during the R-TWT service period corresponding to the j-th R-TWT schedule;

[0337] Wherein, j is a positive integer and j≤m.

[0338] In some embodiments, the transmission efficiency of the delay-sensitive traffic flow during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on the following formula 9:

[0339] in, represents the medium busy time caused by the transmission of delay-sensitive service flows between the AP and the R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT scheduling, It represents the transmission time of the delay-sensitive service flow pre-scheduled during the i-th service cycle in the R-TWT corresponding to the j-th R-TWT scheduling, s represents the number of service cycles in the R-TWT corresponding to the j-th R-TWT scheduling, s is a positive integer, and the time proportion can be expressed by a linear proportion of 255, where 255 represents 100%.

[0340] For example, the delay-sensitive service flow transmission efficiency during the R-TWT service cycle refers to the ratio of the medium busy time caused by the delay-sensitive service flow transmission between the AP and the member STA to the delay-sensitive service flow transmission time pre-scheduled during the R-TWT service cycle.

[0341] In some embodiments, an R-TWT service period utilization rate based on R-TWT member STA transmission during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on at least one of the following: a medium busy time caused by transmission between the AP and the R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT schedule, and a total R-TWT service period duration given during the R-TWT service period corresponding to the j-th R-TWT schedule;

[0342] Wherein, j is a positive integer and j≤m.

[0343] In some embodiments, the R-TWT service period utilization rate based on R-TWT member STA transmission during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on the following formula 10:

[0345] For example, the R-TWT service period utilization (R-TWT SP Utilization) field based on member site transmission is used to define the time proportion of medium busyness caused by transmission between the AP and the member site corresponding to the restricted TWT scheduling, which is monitored by the AP during the R-TWT service period corresponding to the restricted TWT scheduling. The medium busyness can be indicated by the physical carrier sensing (CS) mechanism, and the time proportion can be represented by a linear scale of 255 (255 represents 100%).

[0346] In some embodiments, an R-TWT service period utilization rate based on delay-sensitive traffic flow transmission during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on at least one of the following: a medium busy time caused by delay-sensitive traffic flow transmission between the AP and the R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT schedule, and a total R-TWT service period duration given during the R-TWT service period corresponding to the j-th R-TWT schedule;

[0347] Wherein, j is a positive integer and j≤m.

[0348] In some embodiments, the R-TWT service period utilization rate based on the delay-sensitive service flow transmission during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on the following formula 11:

[0349] in, represents the medium busy time caused by the transmission of delay-sensitive service flows between the AP and the R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT scheduling, represents the duration of the i-th service period in the R-TWT corresponding to the j-th R-TWT scheduling, It represents the cumulative duration of the R-TWT service period corresponding to the j-th R-TWT scheduling, s represents the number of service periods in the R-TWT corresponding to the j-th R-TWT scheduling, s is a positive integer, and the time proportion can be represented by a linear ratio of 255, where 255 represents 100%.

[0350] For example, the R-TWT service period utilization (R-TWT SP Utilization) field based on delay-sensitive service flow transmission is used to define the time proportion of medium busyness caused by the transmission of delay-sensitive service flows between the AP and the member sites corresponding to the restricted TWT scheduling, which is monitored by the AP during the R-TWT service period corresponding to the restricted TWT scheduling. The medium busyness can be indicated by the physical carrier sensing (CS) mechanism, and the time proportion can be represented by a linear ratio of 255 (255 represents 100%).

[0351] In some embodiments, an underutilization rate of an R-TWT service period based on transmissions by non-R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on at least one of the following: a medium busy time caused by transmissions between the AP and non-R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT schedule, and a total duration of an R-TWT service period given during the R-TWT service period corresponding to the j-th R-TWT schedule;

[0352] Wherein, j is a positive integer and j≤m.

[0353] In some embodiments, an R-TWT service period underutilization rate based on transmission by a non-R-TWT member STA during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on the following formula 12:

[0354] in, represents the medium busy time caused by transmission between the AP and non-R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT scheduling, represents the duration of the i-th service period in the R-TWT corresponding to the j-th R-TWT scheduling, It represents the cumulative duration of the R-TWT service period corresponding to the j-th R-TWT scheduling, s represents the number of service periods in the R-TWT corresponding to the j-th R-TWT scheduling, s is a positive integer, and the time proportion can be represented by a linear ratio of 255, where 255 represents 100%.

[0355] For example, the R-TWT SP Underutilization field based on non-member site transmission is used to define the time proportion of medium busyness caused by transmission between the AP and the non-member site corresponding to the restricted TWT scheduling, which is monitored by the AP during the R-TWT service period corresponding to the restricted TWT scheduling. The medium busyness can be indicated by the physical carrier sensing (CS) mechanism, and the time proportion can be represented by a linear scale of 255 (255 represents 100%).

[0356] In some embodiments, the underutilization rate of the R-TWT service period based on the transmission of non-delay-sensitive business flows during the R-TWT service period corresponding to the j-th R-TWT scheduling among the m R-TWT scheduling is determined based on at least one of the following: the medium busy time caused by the transmission between the AP and the non-R-TWT member STA during the R-TWT service period corresponding to the j-th R-TWT scheduling, the medium busy time caused by the transmission of non-delay-sensitive business flows between the AP and the R-TWT member STA during the R-TWT service period corresponding to the j-th R-TWT scheduling, and the total duration of the R-TWT service period given during the R-TWT service period corresponding to the j-th R-TWT scheduling;

[0357] Wherein, j is a positive integer and j≤m.

[0358] In some embodiments, an R-TWT service period underutilization rate based on non-delay-sensitive service flow transmission during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on the following formula 13:

[0359] in, represents the medium busy time caused by the transmission between the AP and non-R-TWT member STAs and the medium busy time caused by the transmission of non-delay-sensitive service flows between the AP and R-TWT member STAs during the R-TWT service period corresponding to the j-th R-TWT scheduling, represents the duration of the i-th service period in the R-TWT corresponding to the j-th R-TWT scheduling, It represents the cumulative duration of the R-TWT service period corresponding to the j-th R-TWT scheduling, s represents the number of service periods in the R-TWT corresponding to the j-th R-TWT scheduling, s is a positive integer, and the time proportion can be represented by a linear ratio of 255, where 255 represents 100%.

[0360] For example, the R-TWT service period underutilization rate (R-TWT SP Underutilization) field based on the transmission of non-delay-sensitive business flows is used to define the time proportion of medium busyness caused by the transmission between the AP and the non-member sites corresponding to the restricted TWT scheduling and the transmission of non-delay-sensitive business flows between the AP and the member sites corresponding to the restricted TWT scheduling during the R-TWT service period corresponding to the restricted TWT scheduling, where the medium busyness can be indicated by the physical carrier sensing (CS) mechanism, and the time proportion can be represented by a linear ratio of 255 (255 represents 100%).

[0361] In some embodiments, the channel utilization ratio during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on at least one of the following: a channel busy time during the R-TWT service period corresponding to the j-th R-TWT schedule, and a total duration of the R-TWT service period given during the R-TWT service period corresponding to the j-th R-TWT schedule;

[0362] Wherein, j is a positive integer and j≤m.

[0363] In some embodiments, the channel utilization ratio during the R-TWT service period corresponding to the jth R-TWT schedule among the m R-TWT schedules is determined based on the following formula 14:

[0364] in, represents the channel busy time during the i-th service period in the R-TWT corresponding to the j-th R-TWT scheduling, represents the channel busy time during the R-TWT service period corresponding to the j-th R-TWT scheduling, represents the duration of the i-th service period in the R-TWT corresponding to the j-th R-TWT scheduling, It represents the cumulative duration of the R-TWT service period corresponding to the j-th R-TWT scheduling, s represents the number of service periods in the R-TWT corresponding to the j-th R-TWT scheduling, s is a positive integer, and the time proportion can be represented by a linear ratio of 255, where 255 represents 100%.

[0367] Wherein, j is a positive integer and j≤m.

[0368] In some embodiments, the channel utilization ratio based on R-TWT member STA transmission during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on the following formula 15:

[0370] For example, the field of channel utilization percentage based on member site transmission during the R-TWT service period is used to define the percentage of medium busy time caused by transmission between the AP and the member site corresponding to the restricted TWT scheduling, relative to the channel busy time, during the R-TWT service period corresponding to the restricted TWT scheduling, where the medium busyness caused by transmission can be indicated by the physical carrier sensing (CS) mechanism, and the channel busyness is the medium busyness monitored by the AP through the physical or virtual carrier sensing (CS) mechanism, where the time percentage can be represented by a linear ratio of 255 (255 represents 100%).

[0371] In some embodiments, the channel utilization ratio based on delay-sensitive service flow transmission during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on at least one of the following: the channel busy time during the R-TWT service period corresponding to the j-th R-TWT schedule, and the medium busy time caused by delay-sensitive service flow transmission between the AP and the R-TWT member STA during the R-TWT service period corresponding to the j-th R-TWT schedule;

[0372] Wherein, j is a positive integer and j≤m.

[0373] In some embodiments, the channel utilization ratio based on delay-sensitive service flow transmission during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on the following formula 16:

[0375] For example, the field of channel utilization percentage based on transmission of delay-sensitive service flows during the R-TWT service period is used to define the ratio of the time of medium busyness caused by the transmission of delay-sensitive service flows between the AP and the member sites corresponding to the restricted TWT scheduling during the R-TWT service period corresponding to the restricted TWT scheduling to the channel busy time. The medium busyness caused by the transmission can be indicated by the physical carrier sensing (CS) mechanism, and the channel busyness is the medium busyness monitored by the AP through the physical or virtual carrier sensing (CS) mechanism. The time ratio can be represented by a linear ratio of 255 (255 represents 100%).

[0376] In some embodiments, the channel idle ratio during the R-TWT service period corresponding to the j-th R-TWT schedule among the m R-TWT schedules is determined based on at least one of the following: the channel busy time during the R-TWT service period corresponding to the j-th R-TWT schedule, and the total duration of the R-TWT service period given during the R-TWT service period corresponding to the j-th R-TWT schedule;

[0377] Wherein, j is a positive integer and j≤m.

[0378] In some embodiments, the channel idle ratio during the R-TWT service period corresponding to the jth R-TWT schedule among the m R-TWT schedules is determined based on the following formula 17:

[0380] For example, the channel idle percentage during the R-TWT service period field is used to define the percentage of channel idle time occupied outside the medium busy time monitored by the AP during the R-TWT service period corresponding to the restricted TWT scheduling, where the medium busyness is monitored by the AP as indicated by the physical or virtual carrier sensing (CS) mechanism, and the time percentage can be represented by a linear scale of 255 (255 represents 100%).

[0381] It should be understood that the above formulas 1 to 17 can be simply transformed to obtain some new formulas, and the transformed formulas also fall within the protection scope of the embodiments of the present application.

[0382] Therefore, in an embodiment of the present application, the STA can obtain the channel utilization information during the R-TWT service period corresponding to all R-TWT schedules established in the first BSS through the delay-sensitive service service period load information, or the STA can obtain the channel utilization information during the R-TWT service period corresponding to the m R-TWT schedules established in the first BSS through the delay-sensitive service service period load information, so that the STA can perform subsequent transmission of the delay-sensitive service flow based on the obtained channel utilization information to optimize the delay-sensitive service flow transmission performance based on R-TWT.
