Description
R-TWT SP planning method, device, equipment and storage medium Technical Field
[0001] The embodiments of the present disclosure relate to the field of communication technology. Specifically, the embodiments of the present disclosure relate to an R-TWT SP planning 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 Wi-Fi technology: Ultra High Reliability (UHR). Its vision is to improve WLAN connection reliability, reduce latency, increase manageability, and increase throughput. UHR technology allows for the transmission of low-latency services through Restricted Target Wake Times (R-TWT) service periods (R-TWT Service Periods). Specifically, the AP broadcasts the R-TWT SP, and STAs join the R-TWT SP to achieve low-latency service transmission between the AP and the STA.
[0003] Since different APs have their own R-TWT SPs, each AP needs to plan its own R-TWT SP so that the low-latency service transmission processes between each AP and its associated STA do not interfere with each other. However, the current existing technology cannot solve the above problem.

[0021] 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.
[0022] In the embodiments of the present disclosure, the term "plurality" refers to two or more than two, and other quantifiers are similar thereto.
[0023] 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.
[0024] 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.
[0025] 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 "at the time of" or "when" or "in response to determining."
[0026] The existing Wi-Fi7 (IEEE 802.11be) architecture mainly transmits low-latency service data through the R-TWT SP mechanism, that is, the AP broadcasts its own R-TWT SP. After the STA associated with the AP joins the R-TWT SP, it can transmit low-latency services with the AP within the R-TWT SP.
[0027] Among them, the R-TWT SP sharing mechanism proposed in UHR technology is shown in Figure 1. AP1, AP2 and AP3 belong to the same central management entity. AP1 can detect the beacon frames of AP2 and AP3. The beacon frames of AP2 and AP3 carry the R-TWT SP of AP2 and AP3 respectively; and AP3 cannot detect the beacon frames of AP2, and AP2 cannot detect the beacon frames of AP3.
[0028] In Figure 1, AP1 can simultaneously broadcast its own R-TWT SP and the R-TWT SP of neighboring APs (AP2 and AP3). In this case, even if AP2 and AP3 cannot listen to each other's beacon frames to obtain each other's R-TWT SP, they can obtain each other's R-TWT SP through AP1.
[0029] The beacon frame includes the Broadcast TWT Parameter Set field:
[0030] The broadcast target wake-up time parameter setting field includes a restricted target wake-up time service information (Restricted TWT Traffic Info) field:
[0031] The restricted target wake-up time service information includes the Traffic Info Control field:
[0032] Among them, the service information control field includes a valid uplink service identification bitmap (UL TID Bitmap Valid) and a downlink service identification bitmap (DL TID Bitmap Valid). The restricted target wake-up time downlink service identification bitmap (Restricted TWT DL TID Bitmap) field and the restricted target wake-up time uplink service identification bitmap (Restricted TWT UL TID Bitmap) field are respectively determined by the AP scheduling R-TWT or the scheduled STA as the TID of the delay-sensitive service flow in the downlink and uplink directions. When the value of the bit at position k in any bitmap is 1, it means that TID k is classified as a delay-sensitive service flow in the corresponding direction of the bitmap. When the value of the bit at position k in any bitmap is 0, it means that TID k is not classified as a delay-sensitive service flow in the corresponding direction.
[0033] In the above scenario, any two APs may have a communication scenario as shown in Figure 2. AP4 can perform low-latency service transmission with its associated STA1 within AP4's R-TWT SP, and AP5 can perform low-latency service transmission with its associated STA2 within AP5's R-TWT SP. However, when STA1 and STA2 are close to each other and the R-TWT SPs of AP4 and AP5 overlap, if AP4 and STA1 perform downlink low-latency service transmission in AP4's R-TWT SP while AP5 and STA2 perform uplink low-latency service transmission in AP5's R-TWT SP, interference will occur between STA2's uplink low-latency service transmission and STA1's downlink low-latency service transmission.
[0034] Based on this, for any AP, after obtaining the R-TWT SP of its neighboring AP, it needs to plan its own R-TWT SP based on the R-TWT SP of the neighboring AP so that the low-latency service transmission between APs does not interfere with each other.
[0035] 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, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present disclosure without creative effort are within the scope of protection of the present disclosure.
[0036] 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.
[0037] The R-TWT SP planning method provided by the embodiment of the present disclosure is summarized below with reference to Figures 3a-3b.
[0038] As shown in Figure 3a, the neighbor AP can directly share the first R-TWT SP of the neighbor AP with the first AP. In this case, the first AP can plan that the second R-TWT SP of the first AP does not overlap with the first R-TWT SP of the neighbor AP.
[0039] As shown in Figure 3b, the neighbor AP can share the first R-TWT SP of the neighbor AP with the second AP, and the second AP can share the first AP of the neighbor AP with the first AP. When the first AP obtains the first R-TWT SP of the neighbor AP through the second AP, if the first AP determines that it has monitored the communication behavior of the neighbor AP, the first AP can plan the second R-TWT SP of the first AP and the first R-TWT SP of the neighbor AP not to overlap, or the first AP can plan the second R-TWT SP for uplink low-latency service transmission and for downlink low-latency service transmission to overlap with the time period of the first R-TWT SP for uplink low-latency service transmission and for downlink low-latency service transmission respectively. If the neighbor AP does not determine that it has detected the communication behavior of the neighbor AP, the first AP can plan the second R-TWT SP of the first AP to not overlap with the first R-TWT SP of the neighbor AP.
[0040] If the second AP shares the neighbor AP's first R-TWT SP with the first AP, the second AP can also share the second AP's third R-TWT SP with the first AP. In this case, the first AP can plan that the first AP's second R-TWT SP does not overlap with the second AP's third R-TWT SP.
[0041] The present disclosure provides an R-TWT SP planning method, which can be applied to a first AP. For details, see FIG4 , which is a flowchart of the R-TWT SP planning method provided by the present disclosure.
[0042] Optionally, the method may include the following steps:
[0043] Step S41: Obtain the first R-TWT SP of the neighboring AP.
[0044] Among them, the first R-TWT SP is used to transmit low-latency services. The STA associated with the neighbor AP and joined the first R-TWT SP can transmit low-latency services with the neighbor AP in the first R-TWT SP.
[0045] Step S42: Plan the second R-TWT SP of the first AP according to the acquisition method of the first R-TWT SP.
[0046] Among them, the first AP is any AP, and the second R-TWT SP of the first AP is used to transmit low-latency services. The STA associated with the first AP and joining the second R-TWT SP can transmit low-latency services with the first AP within the second R-TWT SP.
[0047] After acquiring the first R-TWT SP of the neighboring AP, the first AP may plan the second R-TWT SP of the first AP according to the acquisition method of the first AP acquiring the first R-TWT SP of the neighboring AP.
[0048] The first AP and the neighbor AP may be AP MLDs, or independent APs not affiliated with any AP MLD, which is not limited here.
[0049] In the R-TWT SP planning method applied to a first AP provided in an embodiment of the present disclosure, the first AP obtains a first R-TWT SP of a neighboring AP, including:
[0050] Receive the first R-TWT SP broadcast by the neighboring AP; or,
[0051] The first R-TWT SP of the neighbor shared by the second AP is received, where the first R-TWT SP is shared by the neighbor AP to the second AP.
[0052] That is, the first AP may obtain the first R-TWT SP of the neighbor AP directly from the neighbor AP, or may obtain the first R-TWT SP of the neighbor AP indirectly from other APs.
[0053] That is, when the first AP can hear the broadcast of the neighbor AP, the first AP can receive the first R-TWT SP broadcast by the neighbor AP.
[0054] For example, when the first AP detects a beacon frame of a neighboring AP, the first AP may obtain the first R-TWT SP of the neighboring AP from the beacon frame of the neighboring AP.
[0055] When the first AP cannot detect the broadcast of the neighboring AP, if the second AP can detect the broadcast of the neighboring AP, the second AP broadcasts its own R-TWT SP while broadcasting the first R-TWT SP of the neighboring AP. If the first AP can detect the broadcast of the second AP, the first AP can indirectly obtain the first R-TWT SP of the neighboring AP from the second AP.
[0056] The second AP may share the first R-TWT SP of the neighboring AP with the first AP, and may also share the R-TWT SP of the second AP with the first AP.
[0057] In the R-TWT SP planning method applied to the first AP provided by the embodiment of the present disclosure, the first R-TWT SP and the second R-TWT SP do not overlap.
[0058] Specifically, planning the second R-TWT SP of the first AP according to the first R-TWT SP of the neighboring AP includes:
[0059] When the first AP obtains the first R-TWT SP of the neighbor AP from the neighbor AP, the first AP plans that the second R-TWT SP of the first AP does not overlap with the first R-TWT SP of the neighbor AP.
[0060] That is, when the first R-TWT SP is directly acquired by the first AP from the neighboring AP, the first AP may directly plan that the second R-TWT SP of the first AP does not overlap with the first R-TWT SP of the neighboring AP.
[0061] In the R-TWT SP planning method applied to the first AP provided by the embodiment of the present disclosure, the first R-TWT SP and the second R-TWT SP do not overlap.
[0062] Specifically, planning the second R-TWT SP of the first AP according to the first R-TWT SP of the neighboring AP includes:
[0063] When the first AP obtains the first R-TWT SP of the neighbor AP from the second AP and determines that the communication behavior of the neighbor AP is detected, the first AP plans that the second R-TWT SP of the first AP does not overlap with the first R-TWT SP of the neighbor AP.
[0064] That is, when the first R-TWT SP is indirectly obtained by the first AP from other APs, when the first AP determines that it has monitored the communication behavior of the neighboring AP, the first AP can plan the second R-TWT SP of the first AP to not overlap with the first R-TWT SP of the neighboring AP.
[0065] In the R-TWT SP planning method applied to the first AP provided by the embodiment of the present disclosure, the first R-TWT SP and the second R-TWT SP overlap.
[0066] Specifically, planning the second R-TWT SP of the first AP according to the first R-TWT SP of the neighboring AP includes:
[0067] When the first AP obtains the first R-TWT SP of the neighboring AP from the second AP and determines that the communication behavior of the neighboring AP is monitored, the first AP plans the first and second time periods of the second R-TWT SP to overlap with the third and fourth time periods of the first R-TWT SP of the neighboring AP respectively.
[0068] Among them, the first time period of the second R-TWT SP is used for uplink low-latency service transmission, and the second time period of the second R-TWT SP is used for downlink low-latency service transmission.
[0069] Among them, the third time period of the first R-TWT SP is used for uplink low-latency service transmission, and the fourth time period of the first R-TWT SP is used for downlink low-latency service transmission.
[0070] That is, when the first AP indirectly obtains the first R-TWT SP of the neighboring AP from other APs and determines that the communication behavior of the neighboring AP is monitored, the second R-TWT SP of the first AP is planned so that the time period for uplink low-latency service transmission in the second R-TWT SP overlaps with the time period for uplink low-latency service transmission in the first R-TWT SP, and the time period for downlink low-latency service transmission in the second R-TWT SP overlaps with the time period for downlink low-latency service transmission in the first R-TWT SP.
[0071] In the R-TWT SP planning method applied to the first AP provided by the embodiment of the present disclosure, the first R-TWT SP and the second R-TWT SP overlap.
[0072] Specifically, planning the second R-TWT SP of the first AP according to the first R-TWT SP of the neighboring AP includes:
[0073] When the first AP obtains the first R-TWT SP of the neighbor AP from the second AP and determines that the communication behavior of the neighbor AP is not monitored, the first AP plans a second R-TWT SP to overlap with the first R-TWT SP of the neighbor AP.
[0074] In the R-TWT SP planning method applied to a first AP provided in an embodiment of the present disclosure, the first AP determines and monitors the communication behavior of a neighboring AP, including:
[0075] Get the device association information of neighboring APs;
[0076] Acquire communication report information reported by the first STA, where the communication report information includes device association information of APs other than the first AP that have communication behaviors and are monitored by the first STA;
[0077] When the first AP determines that the communication report information reported by the first STA includes the device association information of the neighbor AP, it determines that the communication behavior of the neighbor is monitored.
[0078] The communication behavior of the neighbor AP may specifically be a behavior of transmitting downlink low-latency services or uplink low-latency services, or may be other behaviors of communicating with associated STAs, which are not limited here.
[0079] The device association information of any AP may be related information that uniquely identifies the AP or the basic service set BSS where the AP is located.
[0080] Optionally, the device association information of any AP includes but is not limited to at least one of identification information (BSSID) of the basic service set where the AP is located, color information (BSS Color) of the basic service set where the AP is located, or the MAC address of the AP.
[0081] When the AP is an AP MLD, the AP's MAC address is the AP MLD MAC address.
[0082] The first STA is associated with the first AP.
[0083] Among them, the communication report information reported by the first STA is determined by the broadcast information received by the first STA from other APs except the first AP, or is determined by the communication behavior of STAs associated with other APs except the first AP within the monitoring range of the first STA through the monitoring equipment. There is no restriction here.
[0084] Optionally, for the first AP, when the first AP determines that the communication report information reported by the first STA does not include the device association information of the neighboring AP, the first AP may determine that no communication behavior of the neighboring AP is monitored.
[0085] Based on the R-TWT SP planning method provided in the embodiment of the present disclosure, the first AP can plan its own second R-TWT SP according to the acquisition method of the first R-TWT SP of the neighboring AP, so that the second R-TWT SP overlaps or does not overlap with the first R-TWT SP, thereby achieving non-interference between different APs and their associated STAs in the low-latency service transmission process.
