[0001] The embodiments of the present disclosure relate to the field of communication technology. Specifically, the embodiments of the present disclosure relate to a low-latency service transmission method, apparatus, device, and storage medium. Background Art

[0002] With the continuous development of Wireless Fidelity (Wi-Fi) technology, researchers have proposed the next generation of Wi-Fi technology: Ultra High Reliability (UHR), with the vision of improving the reliability of WLAN connections, reducing latency, increasing manageability, and increasing throughput.

[0026] In the embodiments of the present disclosure, the term "and / or" describes the association relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent three situations: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally indicates that the associated objects are in an "or" relationship.

[0027] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.

[0028] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. In the following description, unless otherwise indicated, like numbers in different figures represent like or similar elements. The embodiments described in the following exemplary embodiments are not intended to represent all possible embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present invention, as detailed in the appended claims.

[0029] The terms used in this disclosure are for the purpose of describing specific embodiments only and are not intended to limit the disclosure. As used in this disclosure and the appended claims, the singular forms "a," "an," "the," and "the" are intended to include the plural forms, unless the context clearly indicates otherwise. It should also be understood that the term "and / or" as used herein refers to and encompasses any and all possible combinations of one or more of the associated listed items.

[0030] It should be understood that although the terms first, second, third, etc. may be used in this disclosure to describe various information, such information should not be limited to these terms. These terms are only used to distinguish information of the same type from each other. For example, without departing from the scope of this disclosure, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Depending on the context, for example, the word "if" as used herein may be interpreted as "when..." or "when..." or "in response to determining."

[0031] The R-TWT mechanism is defined in the existing Wi-Fi 7 (IEEE 802.11be) architecture to transmit low-latency services. That is, the AP broadcasts the AP's R-TWT SP. STA devices associated with the AP and joining the R-TWT SP can transmit low-latency services with the AP within the R-TWT SP.

[0032] In the existing IEEE 802.11be, when an R-TWT SP starts, a member STA joining the R-TWT SP may suspend decrementing the backoff counter of any access type to which no R-TWT TID is mapped until the STA has delivered all its frames from the R-TWT TID, and resume decrementing the backoff counter thereafter or when the SP ends.

[0033] When a STA affiliated with a Non-AP MLD and operating on one of a pair of NSTR or EMLSR or EMLMR links is a member of an R-TWT SP on the first link; if a second STA affiliated with the same Non-AP MLD is not a member of any other R-TWT SP on the second link that overlaps with the aforementioned R-TWT SP, then if the second STA and its associated AP (referred to as the second AP) each have dot11RestrictedTWTOptionImplemented equal to true, they shall follow the following rules:

[0034] The second AP, being the TXOP holder on the second link, shall ensure that its TXOP ends no later than T time before the start time of the R-TWT SP on the first link.

[0035] The second STA, which is the TXOP holder on the second link, shall ensure that its TXOP ends no later than T time before the start time of the R-TWT SP on the first link.

[0036] Where T is equal to one of the following values:

[0037] If two STAs work on a pair of NSTR links, T is 0;

[0038] If the two STAs belong to a pair of Enhanced Multi-link Single Radio (EMLSR) links, T is the EMLSR transition delay indicated in the EMLSR Transition Delay subfield;

[0039] If two STAs belong to a pair of Enhanced Multi link Multi Radio (EMLMR) links, T is the EMLMR delay indicated in the EMLMR delay subfield.

[0040] However, the existing standard only specifies how the AP and its associated STAs perform low-latency service transmission after broadcasting its own R-TWT SP. However, after the AP obtains the R-TWT SP shared by the neighboring AP, how the AP instructs the STA to perform low-latency service transmission, and how the AP and STA perform low-latency service transmission, there is currently no solution.

[0041] To address the above issues, the following will provide a clear and complete description of the technical solutions in the embodiments of the present disclosure, in conjunction with the accompanying drawings. Obviously, the described embodiments are only a portion of the embodiments of the present disclosure and are not intended to be exhaustive. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without inventive effort are intended to fall within the scope of protection of the present disclosure.

[0042] Among them, the method and the device are based on the same public concept. Since the principles of solving problems by the method and the device are similar, the implementation of the device and the method can refer to each other, and the repeated parts will not be repeated.

[0043] 1 is a schematic diagram of a communication system structure provided by an embodiment of the present disclosure. The system architecture includes a first AP, a neighboring AP, and a first STA. The first STA is associated with the first AP.

[0044] The neighbor AP may share the first R-TWT SP of the neighbor AP with the first AP, and the first AP determines the second R-TWT SP of the first AP according to the first R-TWT SP of the neighbor AP.

[0045] Furthermore, the first AP can determine and send a first wireless frame to the STA, the first wireless frame including the second R-TWT SP of the first AP and the first R-TWT SP of the neighboring AP, and the first wireless frame is used to instruct the first STA to perform low-latency service transmission within the second R-TWT SP according to the first R-TWT SP.

[0046] The following summarizes the low-latency service transmission method provided by the disclosed embodiment with reference to Figure 2. As shown in Figure 2, a first AP can obtain the first R-TWT SP of a neighboring AP. After obtaining the first R-TWT SP of the neighboring AP, the first AP can plan its own R-TWT SP based on the first R-TWT SP shared by the neighboring AP, that is, determine the second R-TWT SP of the first AP, and the first R-TWT SP and the second R-TWT SP do not overlap.

[0047] Furthermore, the first AP determines and sends a first radio frame to the first STA, where the first radio frame includes a first R-TWT SP and a second R-TWT SP, and the first radio frame is used to indicate that low-latency services are transmitted within the second R-TWT SP according to the first R-TWT SP.

[0048] The first wireless frame may be a beacon frame, or a probe response frame or an association response frame replied to the STA, which is not limited here.

[0049] The first AP and the neighbor AP can be independent APs or AP MLDs, without limitation. The first STA can be an independent STA not attached to any Non-AP MLD, an attached STA of a Non-AP MLD, or a Non-AP MLD, without limitation.

[0050] For the first AP or the first STA, the first AP or the first STA can perform low-latency service transmission through at least one first link in the second R-TWT SP of the first AP based on the first R-TWT SP of the neighboring AP.

[0051] When the first AP is an independent AP and the first STA is an independent STA, an affiliated STA of a Non-AP MLD, or a Non-AP MLD, the first AP and the first STA are associated through a communication link, and the first AP and the first STA can perform low-latency service transmission within the second R-TWT SP through the communication link.

[0052] When the first AP is an AP MLD and the first STA is an independent STA or an affiliated STA of a Non-AP MLD, the first AP and the first STA are associated through a communication link, and the first AP and the first STA can perform low-latency service transmission through the communication link within the second R-TWT SP.

[0053] When the first AP is AP MLD and the first STA is Non-AP MLD, the first AP and the first STA can be associated through at least one communication link, and the first AP and the first STA can perform low-latency service transmission through at least one of the communication links within the second R-TWT SP.

[0054] Among them, the communication link used by the first AP and the first STA for low-latency service transmission in the second R-TWT SP is the first link.

[0055] Among them, the communication link supported by the first R-TWT SP for low-latency service transmission is the second link. When the first R-TWT SP is applied to a single link, the first R-TWT SP supports one second link for low-latency service transmission. When the first R-TWT SP is applied to multiple links, the first R-TWT SP supports multiple second communication links for low-latency service transmission.

[0056] For any first link used by the first AP and the first STA for low-latency service transmission within the second R-TWT SP, if the first link is the same link as any second link supported by the first R-TWT SP for low-latency service transmission, or they are NSTR links, eMLSR links or eMLMR links to each other, since the first R-TWT SP and the second R-TWT SP do not overlap, the first AP and the first STA will end the low-latency service transmission before the first R-TWT SP arrives.

[0057] Among them, the first AP or the first STA suspends counting of the backoff counter generated in each first link within the first R-TWT SP. If the first AP and the first STA are associated through multiple communication links, then within the first R-TWT SP, when the first AP or the first STA transmits low-latency services through each first link, for the third link in the communication link between the first AP and the first STA that is an NSTR link, an eMLSR link, or an eMLMR link with each first link, the first AP or the first STA also suspends counting of the backoff counter generated in each third link within the first R-TWT SP.

[0058] Among them, when the first R-TWT SP supports multiple communication links for low-latency service transmission, the first AP can obtain the service-to-link (TID-to-link) mapping information corresponding to the first R-TWT SP from the neighboring AP, and the first STA can obtain the service-to-link mapping information corresponding to the first R-TWT SP from the first AP. The first AP or the first STA can determine that the first R-TWT SP supports multiple second links for low-latency service transmission based on the service-to-link mapping information corresponding to the first R-TWT SP.

[0059] Among them, when the first AP obtains the first R-TWT SP of the neighboring AP, the information field used to carry the first R-TWT SP also includes a calibration (aligned) field. When the value of the calibration field is 1 (first indication information), it is used to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission.

[0060] When the first R-TWT SP supports multiple communication links for low-latency service transmission, the information field of the first wireless frame used to carry the first R-TWT SP also includes a calibration (aligned) field. When the value of the calibration field is 1 (first indication information), it is used to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission.

[0061] When the second R-TWT SP supports multiple communication links for low-latency service transmission, the information field of the first wireless frame used to carry the second R-TWT SP also includes a calibration (aligned) field. When the value of the calibration field is 1 (second indication information), it is used to indicate that the second R-TWT SP supports multiple communication links for low-latency service transmission.

[0062] The embodiment of the present disclosure provides a low-latency service transmission method, which can be applied to a first AP. Specifically, see Figure 3 , which is a schematic flow chart of the low-latency service transmission method provided by the embodiment of the present disclosure.

[0063] Optionally, the method may include the following steps:

[0064] Step S31: Determine a second R-TWT SP according to the first R-TWT SP of the neighboring AP.

[0065] The first AP may directly obtain the first R-TWT SP shared by the neighbor AP from the neighbor AP, or may obtain the first R-TWT SP shared by the neighbor AP to other APs from other APs.

[0066] As an example, the first AP may listen to the broadcast of the neighboring AP to obtain the first R-TWT SP shared by the neighboring AP according to the broadcast of the neighboring AP.

[0067] As an example, the second AP can listen to the neighbor AP's broadcast to obtain the first R-TWT SP shared by the neighbor AP according to the neighbor AP's broadcast. The first AP can listen to the second AP's broadcast to obtain the first AP shared by the neighbor AP according to the second AP's broadcast and simultaneously obtain the second AP's R-TWT SP.

[0068] After obtaining the first R-TWT SP of the neighboring AP, the first AP may plan its own R-TWT SP according to the first R-TWT SP shared by the neighboring AP, that is, determine the second R-TWT SP of the first AP.

[0069] Step S32: Send a first radio frame, where the first radio frame includes a first R-TWT SP and a second R-TWT SP. The first radio frame is used to indicate that the low-latency service is transmitted in the second R-TWT SP according to the first R-TWT SP.

[0070] After determining the second R-TWT SP of the first AP, the first AP may determine and send the first wireless frame.

[0071] The first wireless frame includes the second R-TWT SP of the first AP and the first R-TWT SP of the neighbor AP. The first wireless frame is used to indicate low-latency service transmission in the second R-TWT SP according to the first R-TWT SP of the neighbor AP.

[0072] Optionally, the first radio frame may be a beacon frame, or a probe response frame or an association response frame replied to the STA, which is not limited here.

[0073] The low-latency service transmission method applied to the first AP provided in the embodiment of the present disclosure further includes:

[0074] According to the first R-TWT SP of the neighboring AP, low-latency service transmission is performed through at least one first link in the second R-TWT SP of the first AP.

[0075] The second R-TWT SP and the first R-TWT SP do not overlap.

[0076] The first AP and the neighbor AP can be independent APs or AP MLDs, without limitation. The first STA can be an independent STA not attached to any Non-AP MLD, an attached STA of a Non-AP MLD, or a Non-AP MLD, without limitation.

[0077] Specifically, the first AP may perform low-latency service transmission through at least one first link within the second R-TWT SP based on the second link supported by the first R-TWT SP for low-latency service transmission.

[0078] When the first AP is an independent AP and the first STA is an independent STA, an affiliated STA of a Non-AP MLD, or a Non-AP MLD, the first AP and the first STA are associated through a communication link, and the first AP and the first STA can perform low-latency service transmission within the second R-TWT SP through the communication link.

[0079] When the first AP is an AP MLD and the first STA is an independent STA or an affiliated STA of a Non-AP MLD, the first AP and the first STA are associated through a communication link, and the first AP and the first STA can perform low-latency service transmission through the communication link within the second R-TWT SP.

[0080] When the first AP is AP MLD and the first STA is Non-AP MLD, the first AP and the first STA can be associated through at least one communication link, and the first AP and the first STA can perform low-latency service transmission through at least one of the communication links within the second R-TWT SP.

[0081] Among them, the communication link used by the first AP and the first STA for low-latency service transmission in the second R-TWT SP is the first link.

[0082] In the low-latency service transmission method applied to the first AP provided in the embodiment of the present disclosure, each first link used by the first AP for low-latency service transmission is any communication link among at least one second link, or is an NSTR link, eMLSR link or eMLMR link that performs non-simultaneous transmit and receive (Non-simultaneous transmit and receive) with any second link.

[0083] Among them, each second link is a communication link supported by the first R-TWT SP for low-latency service transmission. Among them, the communication link supported by the first R-TWT SP for low-latency service transmission is a second link. When the first R-TWT SP is applied to a single link, the first R-TWT SP supports one second link for low-latency service transmission. When the first R-TWT SP is applied to multiple links, the first R-TWT SP supports multiple second communication links for low-latency service transmission.

[0084] Optionally, each first link may also be any other communication link except each second link.

[0085] For example, if the communication links supported by the first R-TWT SP for low-latency service transmission are link1, link2 and link3, then for any first link, the first link can be any one of link1, link2 and link3, or any other link except link1, link2 and link3, or link4 (link4 and a second link among link1, link2 or link3 are NSTR links, eMLSR links or eMLMR links).

[0086] Based on this, the first AP can perform low-latency service transmission through at least one first link within the second R-TWT SP.

[0087] As an example, when the first R-TWT SP supports a communication link for low-latency service transmission, that is, the first R-TWT SP is applied to a single link, when the first communication link transmits low-latency service data through the communication link, since the first R-TWT SP and the second R-TWT SP do not overlap, the first AP can transmit low-latency service through the communication link before the first R-TWT SP starts.

[0088] As an example, when the first R-TWT SP supports multiple communication links (assuming link5 and link6) for low-latency service transmission, that is, the first R-TWT SP is applied to multiple links, when there is no communication link that is an NSTR link with link5 in the communication links associated with the first AP, and the first AP transmits low-latency services through link5, since the first R-TWT SP and the second R-TWT SP do not overlap, the first AP can transmit low-latency services through link5 before the first R-TWT SP starts.

[0089] When there is a communication link (such as link7) in the communication links associated with the first AP that is an NSTR link with link6, and the first AP transmits low-latency services through link7, since the first R-TWT SP and the second R-TWT SP do not overlap, the first AP can transmit low-latency services through link7 before the first R-TWT SP starts, thereby avoiding interference with the low-latency service transmission of the neighboring AP on link6 when the low-latency service is transmitted through link7 within the first R-TWT SP.

[0090] In the low-latency service transmission method applied to the first AP provided in the embodiment of the present disclosure, when the first R-TWT SP supports multiple communication links for low-latency service transmission, it also includes:

[0091] Obtain the service-to-link (TID-to-link) mapping information corresponding to the first R-TWT SP from the neighboring AP;

[0092] According to the service-to-link mapping information corresponding to the first R-TWT SP, it is determined that the first R-TWT SP supports multiple second links for low-latency service transmission.

[0093] Among them, the first AP can determine the communication link corresponding to the low-latency service supported by the first R-TWT SP based on the service-to-link mapping information corresponding to the first R-TWT SP, and determine it as the second link supported by the first R-TWT SP for low-latency service transmission.

[0094] When the first AP obtains the first R-TWT SP of the neighboring AP, the information field used to carry the first R-TWT SP also includes first indication information, and the first indication information is used to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission.

[0095] For example, the information field used to carry the first R-TWT SP also includes an aligned field. When the value of the aligned field is 1 (first indication information), it is used to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission.

[0096] Alternatively, after sharing the first R-TWT SP, the neighboring AP may also send first indication information to the first AP to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission. The first AP obtains the first indication information in the same way as it obtains the first R-TWT SP of the neighboring AP.

[0097] Upon receiving the first indication information, the first AP obtains the service-to-link mapping information corresponding to the first R-TWT SP from the neighboring AP. Alternatively, the information field used to carry the first R-TWT SP includes the service-to-link mapping information corresponding to the first R-TWT SP. When the first AP obtains the first R-TWT SP of the neighboring AP, the first AP may synchronously obtain the service-to-link mapping information corresponding to the first R-TWT SP.

[0098] In the low-latency service transmission method applied to the first AP provided in an embodiment of the present disclosure, when the first R-TWT SP supports multiple communication links for low-latency service transmission, the first wireless frame also includes first indication information, and the first indication information is used to indicate that the first R-TWT SP supports multiple link communication links for low-latency service transmission.

[0099] When the second R-TWT SP supports multiple communication links for low-latency service transmission, the first wireless frame also includes second indication information, and the second indication information is used to indicate that the second R-TWT SP supports multiple link communication links for low-latency service transmission.

[0100] Among them, the information field used by the first wireless frame to carry the first R-TWT SP also includes first indication information, and the first indication information is used to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission. For example, the information field used to carry the first R-TWT SP also includes a calibration (aligned) field, and when the value of the calibration field is 1 (first indication information), it is used to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission.

[0101] Similarly, the information field used by the first wireless frame to carry the second R-TWT SP also includes second indication information, and the second indication information is used to indicate that the second R-TWT SP supports multiple communication links for low-latency service transmission. For example, the information field used to carry the second R-TWT SP also includes a calibration (aligned) field, and when the value of the calibration field is 1 (second indication information), it is used to indicate that the second R-TWT SP supports multiple communication links for low-latency service transmission.

[0102] Based on this, the first AP can also indicate to the STA through the first wireless frame whether the first R-TWT SP and the second R-TWT SP support multiple link communication links for low-latency service transmission.

[0103] The low-latency service transmission method applied to the first AP provided in the embodiment of the present disclosure further includes:

[0104] In the first R-TWT SP, the backoff counter generated in each first link is paused for counting.

[0105] That is, within the first R-TWT SP, the first AP does not reduce the number of the backoff counter generated by each first link to indicate that each first link is in a busy state.

[0106] Optionally, for each first link, within the first R-TWT SP, when the first AP transmits low-latency services through the first link, for a third link that is an NSTR link, eMLSR link or eMLMR link with the first link, the first AP also suspends counting of the backoff counter generated in the third link within the first R-TWT SP.

[0107] Optionally, the first AP may also suspend counting of the backoff counter generated in each first link within the second R-TWT SP.

[0108] As an example, for any first link used by the first AP and the first STA for low-latency service transmission within the second R-TWT SP, if the first link is the same link as any second link supported by the first R-TWT SP for low-latency service transmission, or they are NSTR links, eMLSR links or eMLMR links, since the first R-TWT SP and the second R-TWT SP do not overlap, the first AP will end the low-latency service transmission before the first R-TWT SP arrives.

[0109] The first AP suspends counting of the backoff counter generated on each first link within the first R-TWT SP. If the first AP and the first STA are associated through multiple communication links, then within the first R-TWT SP, when the first AP transmits low-latency services through each first link, for a third link in the communication link between the first AP and the first STA that is an NSTR link, an eMLSR link, or an eMLMR link with each first link, the first AP also suspends counting of the backoff counter generated on each third link within the first R-TWT SP.

[0110] The embodiment of the present disclosure provides a low-latency service transmission method, which can be applied to a first STA. For details, see Figure 4 , which is another flowchart of the low-latency service transmission method provided by the embodiment of the present disclosure.

[0111] Optionally, the method may include the following steps:

[0112] Step S41: Receive a first wireless frame, where the first wireless frame includes a first R-TWT SP of a neighboring AP of the first AP and a second R-TWT SP of the first AP. The second R-TWT SP is determined by the first AP based on the first R-TWT SP. The first wireless frame is used to indicate that low-latency services are transmitted within the second R-TWT SP based on the first R-TWT SP.

[0113] The first AP may directly obtain the first R-TWT SP shared by the neighbor AP from the neighbor AP, or may obtain the first R-TWT SP shared by the neighbor AP to other APs from other APs.

[0114] As an example, the first AP may listen to the broadcast of the neighboring AP to obtain the first R-TWT SP shared by the neighboring AP according to the broadcast of the neighboring AP.

[0115] As an example, the second AP can listen to the neighbor AP's broadcast to obtain the first R-TWT SP shared by the neighbor AP according to the neighbor AP's broadcast. The first AP can listen to the second AP's broadcast to obtain the first AP shared by the neighbor AP according to the second AP's broadcast and simultaneously obtain the second AP's R-TWT SP.

[0116] After obtaining the first R-TWT SP of the neighboring AP, the first AP may plan its own R-TWT SP according to the first R-TWT SP shared by the neighboring AP, that is, determine the second R-TWT SP of the first AP.

[0117] After determining the second R-TWT SP of the first AP, the first AP may determine and send the first wireless frame.

[0118] The first wireless frame includes the second R-TWT SP of the first AP and the first R-TWT SP of the neighbor AP. The first wireless frame is used to indicate low-latency service transmission in the second R-TWT SP according to the first R-TWT SP of the neighbor AP.

[0119] Optionally, the first radio frame may be a beacon frame, or a probe response frame or an association response frame replied to the STA, which is not limited here.

[0120] The first AP and the neighbor AP may be independent APs or AP MLDs, which is not limited here.

[0121] The first STA is associated with the first AP and may be an independent STA not attached to any Non-AP MLD, an attached STA of a Non-AP MLD, or a Non-AP MLD, which is not limited here.

[0122] The low-latency service transmission method applied to the first STA provided in the embodiment of the present disclosure further includes:

[0123] According to the first R-TWT SP of the neighboring AP, low-latency service transmission is performed through at least one first link in the second R-TWT SP of the first AP.

[0124] The second R-TWT SP and the first R-TWT SP do not overlap.

[0125] The first STA is associated with the first AP through at least one first link.

[0126] Specifically, the first STA may perform low-latency service transmission through at least one first link within the second R-TWT SP based on the second link for low-latency service transmission supported by the first R-TWT SP.

[0127] When the first AP is an independent AP and the first STA is an independent STA, an affiliated STA of a Non-AP MLD, or a Non-AP MLD, the first AP and the first STA are associated through a communication link, and the first AP and the first STA can perform low-latency service transmission within the second R-TWT SP through the communication link.

[0128] When the first AP is an AP MLD and the first STA is an independent STA or an affiliated STA of a Non-AP MLD, the first AP and the first STA are associated through a communication link, and the first AP and the first STA can perform low-latency service transmission through the communication link within the second R-TWT SP.

[0129] When the first AP is AP MLD and the first STA is Non-AP MLD, the first AP and the first STA can be associated through at least one communication link, and the first AP and the first STA can perform low-latency service transmission through at least one of the communication links within the second R-TWT SP.

[0130] Among them, the communication link used by the first AP and the first STA for low-latency service transmission in the second R-TWT SP is the first link.

[0131] In the low-latency service transmission method applied to the first STA provided in the embodiment of the present disclosure, each first link used by the first STA for low-latency service transmission is any communication link among at least one second link, or is an NSTR link, eMLSR link or eMLMR link that sends and receives non-simultaneously with any second link.

[0132] Among them, each second link is a communication link supported by the first R-TWT SP for low-latency service transmission. Among them, the communication link supported by the first R-TWT SP for low-latency service transmission is a second link. When the first R-TWT SP is applied to a single link, the first R-TWT SP supports one second link for low-latency service transmission. When the first R-TWT SP is applied to multiple links, the first R-TWT SP supports multiple second communication links for low-latency service transmission.

[0133] Optionally, each first link may also be any other communication link except each second link.

[0134] For example, if the communication links supported by the first R-TWT SP for low-latency service transmission are link1, link2 and link3, then for any first link, the first link can be any one of link1, link2 and link3, or any other link except link1, link2 and link3, or link4 (link4 and a second link among link1, link2 or link3 are NSTR links, eMLSR links or eMLMR links).

[0135] Based on this, the first STA can perform low-latency service transmission through at least one first link within the second R-TWT SP.

[0136] As an example, when the first R-TWT SP supports a communication link for low-latency service transmission, that is, the first R-TWT SP is applied to a single link, when the first communication link transmits low-latency service data through the communication link, since the first R-TWT SP and the second R-TWT SP do not overlap, the first STA can transmit low-latency service through the communication link before the first R-TWT SP starts.

[0137] As an example, when the first R-TWT SP supports multiple communication links (assuming link5 and link6) for low-latency service transmission, that is, the first R-TWT SP is applied to multiple links, when there is no communication link that is an NSTR link with link5 in the communication links associated with the first STA, and the first STA transmits low-latency services through link5, since the first R-TWT SP and the second R-TWT SP do not overlap, the first STA can transmit low-latency services through link5 before the first R-TWT SP starts.

[0138] When there is a communication link (such as link7) in the communication links associated with the first STA that is an NSTR link with link6, and the first STA transmits low-latency services through link7, since the first R-TWT SP and the second R-TWT SP do not overlap, the first STA can transmit low-latency services through link7 before the first R-TWT SP starts, thereby avoiding interference with the low-latency service transmission of the first AP's neighbor AP on link6 when the low-latency service is transmitted through link7 within the first R-TWT SP.

[0139] In the low-latency service transmission method applied to the first STA provided in an embodiment of the present disclosure, when the first R-TWT SP supports multiple communication links for low-latency service transmission, it also includes:

[0140] Obtain service-to-link (TID-to-link) mapping information corresponding to the first R-TWT SP from the first AP;

[0141] According to the service-to-link mapping information corresponding to the first R-TWT SP, it is determined that the first R-TWT SP supports multiple second links for low-latency service transmission.

[0142] Among them, the first STA can determine the communication link corresponding to the low-latency service supported by the first R-TWT SP based on the service-to-link mapping information corresponding to the first R-TWT SP, and determine it as the second link supported by the first R-TWT SP for low-latency service transmission.

[0143] When the first AP obtains the first R-TWT SP of the neighboring AP, the information field used to carry the first R-TWT SP also includes first indication information, and the first indication information is used to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission.

[0144] For example, the information field used to carry the first R-TWT SP also includes an aligned field. When the value of the aligned field is 1 (first indication information), it is used to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission.

[0145] Alternatively, after sharing the first R-TWT SP, the neighboring AP may also send first indication information to the first AP to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission. The first AP obtains the first indication information in the same way as it obtains the first R-TWT SP of the neighboring AP.

[0146] Upon receiving the first indication information, the first AP obtains the service-to-link mapping information corresponding to the first R-TWT SP from the neighboring AP. Alternatively, the information field used to carry the first R-TWT SP includes the service-to-link mapping information corresponding to the first R-TWT SP. When the first AP obtains the first R-TWT SP of the neighboring AP, the first AP may synchronously obtain the service-to-link mapping information corresponding to the first R-TWT SP.

[0147] Based on this, the first wireless frame may include the service-to-link mapping information corresponding to the first R-TWT SP, or the first STA may receive the second wireless frame sent by the first AP, and the second wireless frame carries the service-to-link mapping information corresponding to the first R-TWT SP.

[0148] In the low-latency service transmission method applied to the first STA provided in an embodiment of the present disclosure, when the first R-TWT SP supports multiple communication links for low-latency service transmission, the first wireless frame also includes first indication information, and the first indication information is used to indicate that the first R-TWT SP supports multiple link communication links for low-latency service transmission.

[0149] When the second R-TWT SP supports multiple communication links for low-latency service transmission, the first wireless frame also includes second indication information, and the second indication information is used to indicate that the second R-TWT SP supports multiple link communication links for low-latency service transmission.

[0150] Among them, the information field used by the first wireless frame to carry the first R-TWT SP also includes first indication information, and the first indication information is used to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission. For example, the information field used to carry the first R-TWT SP also includes a calibration (aligned) field, and when the value of the calibration field is 1 (first indication information), it is used to indicate that the first R-TWT SP supports multiple communication links for low-latency service transmission.

[0151] Similarly, the information field used by the first wireless frame to carry the second R-TWT SP also includes second indication information, and the second indication information is used to indicate that the second R-TWT SP supports multiple communication links for low-latency service transmission. For example, the information field used to carry the second R-TWT SP also includes a calibration (aligned) field, and when the value of the calibration field is 1 (second indication information), it is used to indicate that the second R-TWT SP supports multiple communication links for low-latency service transmission.

[0152] Based on this, the first AP can also indicate to the STA through the first wireless frame whether the first R-TWT SP and the second R-TWT SP support multiple link communication links for low-latency service transmission.

[0153] The low-latency service transmission method applied to the first STA provided in the embodiment of the present disclosure further includes:

[0154] In the first R-TWT SP, the backoff counter generated in each first link is paused for counting.

[0155] That is, within the first R-TWT SP, the first STA does not reduce the number of the backoff counter generated by each first link.

[0156] Optionally, for each first link, within the first R-TWT SP, when the first STA transmits low-latency services through the first link, for a third link that is an NSTR link, eMLSR link or eMLMR link with the first link, the first STA also suspends counting of the backoff counter generated in the third link within the first R-TWT SP.

[0157] Optionally, the first STA may also suspend counting of the backoff counter generated in each first link within the second R-TWT SP.

[0158] As an example, for any first link used by the first AP and the first STA for low-latency service transmission within the second R-TWT SP, if the first link is the same link as any second link supported by the first R-TWT SP for low-latency service transmission, or they are NSTR links, eMLSR links or eMLMR links, since the first R-TWT SP and the second R-TWT SP do not overlap, the first STA will end the low-latency service transmission before the first R-TWT SP arrives.

[0159] Among them, the first STA suspends counting of the backoff counter generated on each first link within the first R-TWT SP. If the first AP and the first STA are associated through multiple communication links, then within the first R-TWT SP, when the first STA transmits low-latency services through each first link, for the third link in the communication link between the first AP and the first STA that is an NSTR link, an eMLSR link, or an eMLMR link with each first link, the first STA also suspends counting of the backoff counter generated on each third link within the first R-TWT SP.

[0160] Based on the low-latency service transmission method provided by the embodiments of the present disclosure, after a first AP obtains a first R-TWT SP of a neighboring AP, it can plan a second R-TWT SP of the first AP so that the second R-TWT SP and the first R-TWT SP do not overlap.
