Description

Technical Field

[0001] This disclosure relates to the field of communication technology, and more specifically, to an R-TWT protocol adjustment method, apparatus, device, and storage medium. Background Technology

[0002] With the continuous development of Wireless Fidelity (Wi-Fi) technology, researchers have proposed the Restricted Target Wake Time (R-TWT) protocol to ensure low-latency service communication. During the service period (SP) of the R-TWT protocol, only services identified as low-latency can communicate; other services must be suspended or postponed.

[0003] However, the current R-TWT protocol is limited to communication between access points (APs) and stations (STAs) within a single Basic Service Set (BSS). With the diversification of communication service demands and the trend towards higher frequency bands, WLAN device deployments are becoming increasingly dense, leading to a growing prevalence of overlapping Basic Service Sets (OBSSs). While the R-TWT mechanism effectively guarantees the priority transmission of low-latency services within a BSS, in OBSS scenarios, if the R-TWT SPs within each BSS are independent, the service times of the R-TWT protocols in different BSSs may conflict, resulting in signal interference between BSSs. Therefore, a method for adjusting the R-TWT protocol is needed to reduce potential signal conflicts. Summary of the Invention

[0004] This disclosure provides an R-TWT protocol adjustment method, apparatus, device, and storage medium, which can coordinate the R-TWT protocol between at least one AP device in an OBSS scenario and at least one STA device within the BSS, thereby reducing interference between low-latency service communications between BSSs in the OBSS scenario.

[0005] In a first aspect, embodiments of this disclosure provide an R-TWT protocol adjustment method, applicable to a first AP device, the method comprising:

[0006] Receive at least one first message frame, each of the first message frames including a first restricted target wake-up time (R-TWT) protocol between a second AP device and at least one site STA device in the basic service set (BSS) where the first AP device and each of the second AP devices form an overlapping basic service set (OBSS);

[0007] At least one second R-TWT protocol is adjusted based on each of the received first R-TWT protocols, wherein each second R-TWT protocol is an R-TWT protocol between the first AP device and a STA device within the BSS.

[0008] Secondly, embodiments of this disclosure also provide an R-TWT protocol adjustment device, the device comprising:

[0009] A communication unit is configured to receive at least one first message frame, each of the first message frames including a first restricted target wake-up time (R-TWT) protocol between a second AP device and at least one site STA device within the basic service set (BSS), wherein the first AP device and each of the second AP devices form an overlapping basic service set (OBSS).

[0010] The adjustment unit is configured to adjust at least one second R-TWT protocol according to the received first R-TWT protocols, wherein each second R-TWT protocol is an R-TWT protocol between the first AP device and a STA device within the BSS.

[0027] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0028] The method and apparatus are based on the same disclosed concept. Since the methods and apparatus solve problems in similar ways, the implementation of the apparatus and methods can refer to each other, and repeated parts will not be described again.

[0029] An AP device can be a wireless switch for a wireless network, or an access device for a wireless network. An AP device may include software applications and / or circuitry to enable other types of nodes in the wireless network to communicate with the outside and inside of the wireless network. As an example, an AP device may be a terminal device or network device equipped with a Wi-Fi chip.

[0030] Specifically, STA devices may include, but are not limited to: cellular phones, smartphones, wearable devices, computers, personal digital assistants (PDAs), personal communication system (PCS) devices, personal information managers (PIMs), personal navigation devices (PNDs), global positioning systems, multimedia devices, and Internet of Things (IoT) devices.

[0031] This disclosure provides an R-TWT protocol adjustment method that can be applied to a first AP device. See details below. Figure 1 , Figure 1 This is a flowchart illustrating the R-TWT protocol adjustment method provided in this embodiment.

[0032] Optionally, the method may include the following steps:

[0033] Step S11: Receive at least one first message frame, each first message frame including a first R-TWT protocol between a second AP device and at least one site STA device within the basic service set BSS.

[0034] In this embodiment of the disclosure, the first AP device and each of the second AP devices form an Overlapping Basic Service Set (OBSS), and the first AP device is any one of the AP devices that form the OBSS.

[0035] In a wireless LAN, a BSS can consist of an AP device and one or more site devices communicating with that AP device. A basic service set can connect to a distribution system (DS) through its AP device, and then connect to another basic service set to form an extended service set (ESS).

[0036] Alternatively, the AP device can be a device with wireless-to-wired bridging capabilities, which extends the services provided by the wired network to the wireless network; the STA device can be an electronic device with wireless network access capabilities, which provides frame delivery services to enable information transmission.

[0037] In this embodiment of the disclosure, the overlapping portion of the BSS formed by at least one AP device is the OBSS, and any AP device or STA device in this embodiment of the disclosure can be a device that supports multi-link device (MLD), for example, it can be represented as AP MLD and Non-AP MLD respectively.

[0038] As a first example, see Figure 2 as well as Figure 3 AP MLD can represent an access point device that supports multiple connection communication functions, while non-AP MLD can represent a site device that supports multiple connection communication functions.

[0039] Reference Figure 2 An AP MLD can include three auxiliary AP devices, such as Figure 2 The diagram shows AP1, AP2, and AP3; each AP device can operate in Connection 1, Connection 2, and Connection 3 respectively; a non-AP MLD can also include three auxiliary STA devices, such as... Figure 2The diagram shows STA1, STA2, and STA3; STA1 operates at connection 1, STA2 operates at connection 2, and STA3 operates at connection 3. Figure 3 In this context, AP1 and STA1 constitute BSS1, and AP2 and STA2 constitute BSS2. Figure 2 In the example, assume AP1 communicates with STA1 via the corresponding first connection, Link 1; similarly, AP2 communicates with STA2 via the corresponding second connection, Link 2; and the AP device communicates with STA3 via the third connection, Link 3. Furthermore, Links 1 to 3 can be multiple connections at different frequencies, such as connections at 2.4GHz, 5GHz, and 6GHz, or several connections with the same or different bandwidths at 2.4GHz. Additionally, multiple channels can exist under each connection. It is understood that... Figure 2 The communication scenarios shown are merely exemplary, and the present disclosure is not limited thereto. For example, the AP MLD can be connected to multiple (three) non-AP MLDs, or under each connection, the AP device can communicate with multiple other types of site devices.

[0040] like Figure 4 As shown, Figure 4 This is a schematic diagram of an OBSS scenario provided in an embodiment of this disclosure. AP1 forms BSS1 within a certain frequency band, and AP2 forms BSS2 within the same frequency band. The overlapping part of BSS1 and BSS2 is the OBSS.

[0041] STA1 and STA2 are both located inside OBSS, while STA3 is located outside OBSS. STA1 and STA3 have established communication connections with AP1 and can communicate with AP1. STA2 has established a communication connection with AP2 and can communicate with AP2.

[0042] In this embodiment of the disclosure, any AP device forming an OBSS can send a first message frame to other AP devices corresponding to that OBSS. For each first AP device, the first message frame sent by the AP device includes the R-TWT protocol between the AP device and at least one STA device within its BSS.

[0043] In this embodiment, the first AP device is any AP device corresponding to the OBSS, and the other AP devices besides the first AP device among all AP devices corresponding to the OBSS are the second AP devices. For the first AP device in this embodiment, the first AP device can receive a first message frame sent by at least one second AP device. Each first message frame sent by the second AP device includes the R-TWT protocol (referred to as the first R-TWT protocol in this embodiment for ease of description) between the second AP device and at least one STA device within its BSS.

[0044] As an example, the first AP device can receive the first message frame sent by all the second AP devices.

[0045] As an example, the first message frame sent by each second AP device includes a first R-TWT protocol between the second AP device and at least one STA device in the BSS, and the second AP device has an independent first R-TWT protocol with each STA device in the BSS.

[0046] As an example, the first message frame sent by each second AP device includes a first R-TWT protocol between the second AP device and at least one STA device located in the OBSS within the BSS.

[0047] The first message frame sent by each AP device can be a beacon frame.

[0048] Step S12: Adjust at least one second R-TWT protocol according to the received first R-TWT protocols. Each second R-TWT protocol is an R-TWT protocol between the first AP device and a STA device in the BSS.

[0049] In this embodiment of the disclosure, the first AP device may adjust the second R-TWT protocol between the first AP device and at least one STA device in the BSS according to the received first R-TWT protocols.

[0050] Optionally, the first AP device can determine whether the second R-TWT protocol with each STA device within its BSS supports inter-BSS coordination functions, and then adjust the second R-TWT protocol that supports inter-BSS coordination functions according to the received first R-TWT protocols, so that the service time of the second R-TWT protocol that supports inter-BSS coordination functions after adjustment is independent of the following service times:

[0051] The service time of the first R-TWT protocol that does not support the coordination function between BSSs among the received first R-TWT protocols;

[0052] The service time of the first R-TWT protocol that supports the coordination function between BSSs after adjustment among the received first R-TWT protocols.

[0053] In this process, the first R-TWT protocol for each BSS-supporting coordination function is adjusted by the second AP device that sends the first message frame including the first R-TWT protocol.

[0054] Optionally, for each second R-TWT protocol that supports inter-BSS coordination, if the second R-TWT protocol supports time-domain coordination, the first AP device can adjust the time slot of the service time of the second R-TWT protocol. If the second R-TWT protocol supports frequency-domain coordination, the first AP device can adjust the frequency-domain resources of the service time of the second R-TWT protocol, such as reallocating channel bandwidth.

[0055] In the R-TWT protocol adjustment method for a first AP device provided in this disclosure, each first message frame includes at least one Broadcast TWT Parameter Set field, and each Broadcast TWT Parameter Set field includes a first R-TWT protocol between a second AP device and a STA device within the BSS.

[0056] For each second AP device sending a first message frame, the first message frame includes at least one broadcast target wake-up time parameter setting field. Each broadcast target wake-up time parameter setting field includes a first R-TWT protocol between the second AP device and a STA device in the BSS, which may specifically include service time, target wake-up time and other related protocol information.

[0057] Optionally, each first message frame includes a target wake-up time element (TWT element) field, which includes a target wake-up time information (TWT Parameter Information) field, and the target wake-up time information field includes at least one broadcast target wake-up time.

[0058] In the R-TWT protocol adjustment method for the first AP device provided in this disclosure, each broadcast target wake-up time parameter setting field further includes a first identifier bit. The first identifier bit indicates by a first value that the first R-TWT protocol included in the broadcast target wake-up time parameter setting field supports the coordination function between BSSs, and indicates by a second value that the first R-TWT protocol included in the broadcast target wake-up time parameter setting field does not support the coordination function between BSSs.

[0059] The first value can be 1, and the second value can be 0; there are no restrictions here.

[0060] The first identifier bit can be the Restricted Target Wake-up Time Coordination Support (RTWCoordination Support) identifier bit.

[0061] As an example, for each second AP device, the first message frame sent by each second AP device includes multiple broadcast target wake-up time parameter setting fields. Each broadcast target wake-up time parameter setting field includes a first R-TWT protocol between the second AP device and a STA device within the BSS. Each broadcast target wake-up time parameter setting field also includes a first identifier bit. The first identifier bit in each broadcast target wake-up time parameter setting field indicates by a first value that the first R-TWT protocol in the same broadcast target wake-up time parameter setting field supports the coordination function between BSSs, and indicates by a second value that the first R-TWT protocol in the same broadcast target wake-up time parameter setting field does not support the coordination function between BSSs.

[0062] In the R-TWT protocol adjustment method for a first AP device provided in this disclosure, each broadcast target wake-up time parameter setting field in each first message frame includes a broadcast target wake-up time information field (Broadcast TWT Infosubfield), and each broadcast target wake-up time information field includes a first flag bit for indicating whether the first R-TWT protocol in the corresponding broadcast target wake-up time parameter setting field supports the coordination function between BSSs.

[0063] As an example, the wake-up time parameter setting field for any broadcast target can be set as follows:

[0064]

[0065] The Broadcast TWT Parameter Set field includes the Broadcast TWT Info field, which can be two octets.

[0066] As an example, the wake-up time information field for any broadcast target can be as follows:

[0067]

[0068] The Broadcast TWT Info subfield includes a Restricted TWT Coordination Support flag, which is the first flag used to indicate whether the R-TWT protocol in the same Broadcast TWT parameter setting field supports coordination between BSSs.

[0069] The Restricted TWT Coordination Support flag can be 1 bit.

[0070] In the R-TWT protocol adjustment method for a first AP device provided in this disclosure, for each first message frame, when the first R-TWT protocol included in each broadcast target wake-up time parameter setting field of the first message frame supports the coordination function between BSSs, that is, when the identifier value of the first identifier bit included in each broadcast target wake-up time parameter setting field of the first message frame is a first value, the broadcast target wake-up time parameter setting field also includes a second identifier bit, which is used to indicate the coordination type supported by the first R-TWT protocol included in the broadcast target wake-up time parameter setting field.

[0071] Specifically, for each first message frame, when the first R-TWT protocol included in the broadcast target wake-up time parameter setting field of the first message frame supports the coordination function between BSSs, that is, when the identifier value of the first identifier bit included in each broadcast target wake-up time parameter setting field of the first message frame is the first value, the broadcast target wake-up time parameter setting field also includes a second identifier bit. The second identifier bit indicates through a third value that the first R-TWT protocol included in the broadcast target wake-up time parameter setting field supports time domain coordination (Time slots based coordination), and through a fourth value that the first R-TWT protocol included in the broadcast target wake-up time parameter setting field supports frequency domain coordination (Frequency domain based coordination).

[0072] The second identifier bit mentioned above can be a Coordination Type identifier bit, and there are no restrictions on this.

[0073] The third value can be 0 and the fourth value can be 1, without any restrictions.

[0074] In the R-TWT protocol adjustment method for a first AP device provided in this disclosure, for each first message frame, the broadcast target wake-up time parameter setting field of the first message frame further includes a third identifier bit, which is used to indicate the number of AP devices in the OBSS.

[0075] The third identifier can be the Number of AP in OBSS identifier, and there are no restrictions on this.

[0076] Specifically, for each first message frame, each broadcast target wake-up time parameter setting field in the first message frame includes a restricted target wake-up time coordination information (Restricted TWT Coordination Info) field, and the restricted target wake-up time coordination information field in each broadcast target wake-up time parameter setting field includes the aforementioned third identifier bit.

[0077] In the R-TWT protocol adjustment method for a first AP device provided in this disclosure, for each first message frame, when the first R-TWT protocol included in each broadcast target wake-up time parameter setting field of the first message frame supports the coordination function between BSSs, that is, when the identifier value of the first identifier bit included in each broadcast target wake-up time parameter setting field of the first message frame is a first value, the broadcast target wake-up time parameter setting field also includes a Restricted TWT Coordination Info field, which includes a second identifier bit for indicating the supported coordination type included in the same broadcast target wake-up time parameter setting field.

[0078] As an example, the wake-up time parameter setting field for any broadcast target can be set as follows:

[0079]

[0080] The Broadcast TWT Parameter Set includes a Restricted TWT Coordination Info field, which can be one octet.

[0081] As an example, the wake-up time coordination information field for any restricted target can be as follows:

[0082]

[0083] The Restricted TWT Coordination Info field includes a third identifier (Number of APs in OBSS), and a second identifier (Coordination Type) when the corresponding R-TWT protocol supports inter-BSS coordination. The third identifier indicates the number of AP devices in the OBSS, and the second identifier indicates the coordination type supported by the R-TWT protocol in the same broadcast target wake-up time parameter setting field when supporting inter-BSS coordination.

[0084] The second identifier (Coordination Type) can be 2 bits, and the third identifier (Number of AP in OBSS) can be 3 bits.

[0085] When the value of the second flag bit (Coordination Type) is 0, it indicates that the R-TWT protocol included in the same broadcast target wake-up time parameter setting field supports time-domain coordination (Time slots based coordination). When the value of the second flag bit (Coordination Type) is 1, it indicates that the R-TWT protocol included in the same broadcast target wake-up time parameter setting field supports frequency-domain coordination (Frequency domain based coordination).

[0086] In the R-TWT protocol adjustment method for a first AP device provided in this disclosure, at least one second R-TWT protocol is adjusted according to each received first R-TWT protocol, including: when there is at least one R-TWT protocol that supports time-domain coordination among the second R-TWT protocols (in this embodiment of the disclosure, the second R-TWT protocol that supports time-domain coordination is referred to as the third R-TWT protocol), the service time of each third R-TWT protocol is adjusted.

[0087] The service time of each adjusted third R-TWT protocol is located after the service time of all R-TWT protocols that do not support time-domain coordination. In other words, the service time of each adjusted third R-TWT protocol is located after all first and second R-TWT protocols that do not support time-domain coordination.

[0088] Optionally, if none of the received first R-TWT protocols support time-domain coordination, the service time of each adjusted third R-TWT protocol is located after the service times of all second R-TWT protocols that do not support time-domain coordination and all first R-TWT protocols.

[0089] If none of the received first R-TWT protocols support time-domain coordination, then the service times of each adjusted third R-TWT protocol are independent of each other, meaning that the service times of each adjusted third R-TWT protocol do not overlap.

[0090] Furthermore, the order of service times for each adjusted third R-TWT protocol is consistent with the order of target wake-up times for the original third R-TWT protocol. In other words, the order of target wake-up times for each adjusted third R-TWT protocol is consistent with the order of target wake-up times for the original third R-TWT protocol.

[0091] Optionally, if at least one of the received first R-TWT protocols supports time-domain coordination (in this embodiment, the first R-TWT protocol supporting time-domain coordination is referred to as the fourth R-TWT protocol), for each fourth R-TWT protocol, the service time of the fourth R-TWT protocol is adjusted by the second AP device that sends the first message frame including the fourth R-TWT protocol, so that the service time of each adjusted third R-TWT protocol and the service time of each adjusted fourth R-TWT protocol are after the service times of all second R-TWT protocols that do not support time-domain coordination and all first R-TWT protocols that do not support time-domain coordination.

[0092] If at least one fourth R-TWT protocol that supports time-domain coordination exists among the received first R-TWT protocols, then the service times of each adjusted third R-TWT protocol and each adjusted fourth R-TWT protocol are independent of each other, that is, the service times of each adjusted third R-TWT protocol and each adjusted third R-TWT protocol do not overlap.

[0093] Furthermore, the service times of each adjusted third R-TWT protocol and each adjusted fourth R-TWT protocol are in the same order as the first order, that is, the target wake-up times of each adjusted third R-TWT protocol and each adjusted fourth R-TWT protocol are in the same order as the first order.

[0094] The first order is the order of the target wake-up times of the various third R-TWT protocols and the various fourth R-TWT protocols before the adjustment.

[0095] Based on this, after each AP device in OBSS adjusts the service time of the R-TWT protocol that supports time-domain coordination, the service times of each adjusted R-TWT protocol do not overlap. Therefore, when the AP device and STA device corresponding to each adjusted R-TWT protocol communicate, there will be no signal interference between the communication links.

[0096] In the R-TWT protocol adjustment method for a first AP device provided in this disclosure, adjusting at least one second R-TWT protocol according to each received first R-TWT protocol, further comprising: when there is at least one R-TWT protocol that supports frequency domain coordination among the second R-TWT protocols (in this embodiment, the second R-TWT protocol that supports frequency domain coordination is referred to as the fifth R-TWT protocol), adjusting the frequency domain resources of each fifth R-TWT protocol.

[0097] Optionally, if none of the received first R-TWT protocols support frequency domain coordination, then the frequency domain resources of each adjusted fifth R-TWT protocol are independent of each other.

[0098] Optionally, if at least one R-TWT protocol that supports frequency domain coordination exists among all the received first R-TWT protocols (in this embodiment, the first R-TWT protocol that supports frequency domain coordination is referred to as the sixth R-TWT protocol), for each sixth R-TWT protocol, the second AP device that sends the first message frame including the sixth R-TWT protocol adjusts the frequency domain resources of the sixth R-TWT protocol so that the frequency domain resources of each adjusted fifth R-TWT protocol and each adjusted sixth R-TWT protocol are independent of each other, that is, the frequency domain resources of each adjusted fifth R-TWT protocol and each adjusted sixth R-TWT protocol do not overlap.

[0099] When any AP device adjusts the frequency domain resources of any R-TWT protocol that supports frequency domain coordination, it can allocate independent frequency domain resources for that R-TWT protocol, such as channel bandwidth for low-latency service communication, without any restrictions.

[0100] In the R-TWT protocol adjustment method for a first AP device provided in this disclosure, the first AP device can also send a first message frame to each of the second APs. The first message frame sent by the first AP device includes the second R-TWT protocol between the first AP device and at least one STA device in the BSS, so that each second AP device can adjust the R-TWT protocol between the second AP and at least one STA device in the BSS according to the R-TWT protocol received from other AP devices.

[0101] The first message frame sent by the first AP device also includes at least one broadcast target wake-up time parameter setting field, and each broadcast target wake-up time parameter setting field includes a second R-TWT protocol.

[0102] In the first message frame sent by the first AP device, each broadcast target wake-up time parameter setting field also includes a first identifier bit. The first identifier bit indicates by a first value that the second R-TWT protocol included in the broadcast target wake-up time parameter setting field supports the coordination function between BSSs, and indicates by a second value that the second R-TWT protocol included in the broadcast target wake-up time parameter setting field does not support the coordination function between BSSs.

[0103] In the first message frame sent by the first AP device, when the second R-TWT protocol included in each broadcast target wake-up time parameter setting field supports the coordination function between BSSs, the broadcast target wake-up time parameter setting field also includes a second identifier bit. The second identifier bit indicates through a third value that the second R-TWT protocol included in the broadcast target wake-up time parameter setting field supports time domain coordination, and through a fourth value that the second R-TWT protocol included in the broadcast target wake-up time parameter setting field supports frequency domain coordination.

[0104] In the first message frame sent by the first AP device, each broadcast target wake-up time parameter setting field includes a broadcast target wake-up time information field, and the broadcast target wake-up time information field includes a first identifier bit.

[0105] In the first message frame sent by the first AP device, each broadcast target wake-up time parameter setting field includes a restricted target wake-up time coordination information field, which includes a third identifier bit. The third identifier bit is used to indicate the number of AP devices in the OBSS.

[0106] In the first message frame sent by the first AP device, when the second R-TWT protocol supports the coordination function between BSSs, the restricted target wake-up time coordination information field includes a second identifier bit in each broadcast target wake-up time parameter setting field.

[0107] According to the R-TWT protocol adjustment method provided in this disclosure, the time-domain coordinated R-TWT protocols between at least one AP device in the OBSS and at least one STA device in the BSS can be adjusted, thereby making the service times of the adjusted time-domain coordinated R-TWT protocols independent of each other, reducing interference between communication links when the corresponding AP devices and STA devices conduct low-latency service communication. Simultaneously, the frequency-domain coordinated R-TWT protocols between at least one AP device in the OBSS and at least one STA device in the BSS can be adjusted, thereby making the frequency domain resources of the adjusted frequency-domain coordinated R-TWT protocols independent of each other, reducing interference caused by frequency domain resource overlap during low-latency service communication.
