[0003] To ensure the transmission of low-latency service data, a restricted target wake time (R-TWT) has been proposed. To further reduce the transmission capacity constraints and interference during the transmission of low-latency service data, the transmission process needs to be optimized.
[0004] Summary of the Invention
[0005] The embodiments of the present disclosure provide a low-latency service transmission method, an electronic device, and a storage medium to provide a low-latency service data transmission method.
[0006] In one aspect, an embodiment of the present disclosure provides a low-latency service transmission method, applied to a first access point device AP, the method comprising:
[0007] Determine a first radio frame; wherein the first radio frame includes a second R-TWT SP of the second AP and time synchronization parameter TSF information of the second AP;
[0008] A first radio frame is sent to instruct the station device STA to determine the time of the second R-TWT SP according to the above TSF information and the second R-TWT SP, and not to communicate with the first AP during the time of the second R-TWT SP.
[0009] On the other hand, an embodiment of the present disclosure further provides a low-latency service transmission method, applied to a station device STA, the method comprising:
[0010] Receive a first wireless frame sent by a first access point device AP; wherein the first wireless frame includes a second R-TWT SP of a second AP and TSF information of the second AP;
[0011] The time of the second R-TWT SP is determined according to the TSF information and the second R-TWT SP, and no communication is performed with the first AP during the time of the second R-TWT SP.
[0012] On the other hand, an embodiment of the present disclosure further provides an electronic device, wherein the electronic device is a first access point device AP, and the electronic device includes:
[0013] A determination module, configured to determine a first radio frame; wherein the first radio frame includes a second R-TWT SP of a second AP and TSF information of the second AP;
[0014] The sending module is used to send a first wireless frame to instruct the station device STA to determine the time of the second R-TWT SP according to the TSF information and the second R-TWT SP, and not to communicate with the first AP during the time of the second R-TWT SP.
[0015] On the other hand, an embodiment of the present disclosure further provides an electronic device, where the electronic device is a station device STA, and the electronic device includes:
[0016] A receiving module, configured to receive a first wireless frame sent by a first access point device AP; wherein the first wireless frame includes a second R-TWT SP of a second AP and TSF information of the second AP;
[0017] The communication module is configured to determine the time of the second R-TWT SP according to the TSF information and the second R-TWT SP, and not communicate with the first AP during the time of the second R-TWT SP.
[0018] An embodiment of the present disclosure further provides an electronic device, including a memory, a processor, and a computer program stored in the memory and executable on the processor.

[0020] In the disclosed embodiment, a first AP determines a first radio frame, wherein the first radio frame includes a second R-TWT SP of a second AP and TSF information of the second AP. The first radio frame is then transmitted to instruct a STA to determine the time of the second R-TWT SP based on the TSF information and the second R-TWT SP, and not to communicate with the first AP during the time of the second R-TWT SP. In this way, a STA that receives the first radio frame can determine the actual time (i.e., the time of the second R-TWT SP) when the second R-TWT SP is shared by the first AP based on the TSF information and the second R-TWT SP in the first radio frame. Specifically, the STA synchronizes the time generated when the second R-TWT SP is shared by the first AP with the time generated when the second R-TWT SP is shared by the second AP. The STA also avoids communicating with the first AP during the time of the second R-TWT SP, thereby preventing interference with low-latency service communications within the second R-TWT SP when the STA communicates with the first AP. This ensures both the service data transmission between the first AP and the STA and the communication of low-latency services within the second R-TWT SP, thereby improving data transmission efficiency and spectrum utilization. The disclosed embodiment provides a low-latency service data transmission method.

[0033] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure and not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present disclosure.
[0034] The embodiments of the present disclosure provide a low-latency service transmission method, an electronic device, and a storage medium, for providing a mechanism to support AP power saving.
[0035] Among them, the method and the device are based on the same application 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.
[0036] Referring to Figure 1, there are three APs under the same central management entity, namely AP1, AP2, and AP3. AP2 and AP1 are neighboring APs, AP1 and AP3 are neighboring APs, and AP2 and AP3 have no neighbor relationship. The R-TWT SP sharing mechanism for AP1, AP2, and AP3 can include the following:
[0037] (1) AP1 can monitor the beacon frames of AP2 and AP3. AP2 cannot monitor the beacon frames of AP3.
[0038] (2) AP3 cannot detect the beacon frame of AP2.
[0039] (3) AP1 broadcasts the first R-TWT SP of AP1, the second R-TWT SP of AP2, the neighbor of AP1, and the third R-TWT SP of AP3, the neighbor of AP1.
[0040] That is, AP1 will broadcast the second R-TWT SP of AP2 and the third R-TWT SP of AP3 to the STA associated with AP1 (in the embodiment of the present disclosure, it may be referred to as STA1).
[0041] In the embodiment of the present disclosure, if one AP broadcasts the R-TWT SP of other APs, the other APs may be referred to as shared APs.
[0042] Optionally, AP1 and the shared AP can be attached APs of the same or different AP MLDs, or different AP MLDs or independent APs, without limitation herein. Optionally, AP1 is attached to a first AP MLD, and the shared AP is attached to a second AP MLD. AP1 can be within a certain location range or coverage range from the shared AP, so that AP1 can obtain parameter information of the shared AP, for example, AP1 can obtain the R-TWT SP of the shared AP.
[0043] Any two APs may transmit data via beacon frames or probe response frames, wherein the probe response frames may be unsolicited probe response frames.
[0044] Among them, the start time of each R-TWT SP is associated with its broadcasting AP. Taking the second R-TWT SP as an example, when the second R-TWT SP is broadcast by the second AP and the first AP respectively, there is a deviation in the start time of the two second R-TWT SPs generated. Under normal circumstances, the second AP and its associated STA (which can be referred to as STA2 in the embodiment of the present disclosure) transmit low-latency service data within the second R-TWT SP. Therefore, if the second R-TWT SP is directly broadcast by the first AP to STA1, the generated second R-TWT SP is different from the second R-TWT SP shared by the second AP with STA2 (that is, the actual communication time within the second R-TWT SP). This may cause the second AP and STA2 to transmit low-latency service data within the second R-TWT SP while STA1 also communicates with the first AP, causing interference to the low-latency service data transmission between the second AP and STA2.
[0045] To address this, a low-latency service data transmission method is proposed in the embodiments of the present disclosure. As a first example, see Figure 2, which shows an example of a low-latency service transmission method provided by various embodiments of the present disclosure. As shown in Figure 2, the method may include the following steps:
[0046] Step 1: AP1 determines a first radio frame according to the acquired R-TWT SP of the shared AP. The first radio frame includes the R-TWT SP of the shared AP and TSF (Timing Synchronization Function) information of the shared AP.
[0047] In the embodiments of the present disclosure, unless otherwise specified, the shared R-TWT SP may be used to refer to the R-TWT SP of the shared AP; in special cases, for example, if the shared AP includes multiple APs, such as AP2 and AP3, the shared R-TWT SP shared by AP2 may be called the second R-TWT SP, and the shared R-TWT SP shared by AP3 may be called the third R-TWT SP.
[0048] Optionally, when AP1 determines the first wireless frame, identification information of the shared AP may be set in the first wireless frame to identify different shared APs. The identification information may include at least one of a MAC address (Media Access Control Address), an AP MLD (Access Point Multi-Link Device) address of the shared AP, a Basic Service Set color (BSS color), and BSSID information.
[0049] Optionally, when there are multiple shared APs, after setting the identification information of each shared AP in the first wireless frame, AP1 can associate the set shared AP identification information, shared R-TWT SP and TSF information according to different shared APs.
[0050] Taking the identification information including the MAC address as an example, as shown in Figure 1, if the shared AP includes AP2 and AP3, AP1 can set the second MAC address of AP2 in the first wireless frame, and associate the second MAC address, the second R-TWT SP and the second TSF information; set the third MAC address of AP3 in the first wireless frame, and associate the third MAC address, the third R-TWT SP and the third TSF information.
[0051] Optionally, the TSF information may include TSF offset parameter information, and the TSF offset parameter information may include time offset time, wherein the time offset time indicates the offset time between the start times of two R-TWT SPs generated when the shared R-TWT SP is broadcast directly through AP1 and the shared AP respectively.
[0052] As an example, when the shared R-TWT SP is broadcast directly by AP1, the shared R-TWT SP generated is t1 to t2. When the shared R-TWT SP is broadcast directly by the shared AP, the shared R-TWT SP generated (i.e., the time of actual communication within the shared R-TWT SP) is t3 to t4. Among them, when the shared R-TWT SP is broadcast directly by AP1 and the shared AP respectively, the duration of the two shared R-TWT SPs generated is the same, i.e., s=t2-t1=t4-t3. Then, when the shared R-TWT SP is sent directly by AP1 and the shared AP respectively, the offset time between the start times of the two shared R-TWT SPs generated (i.e., time offset time) is t'=t3-t1.
[0053] Optionally, in an embodiment of the present disclosure, AP1 may set an aligned flag in the first radio frame. For example, the aligned flag may be carried in the Broadcast TWT Parameter Set field of the R-TWT SP information. By setting the aligned flag to a different value, it indicates the connection to which the R-TWT SP is applied.
[0054] For example, when the aligned flag is set to 1, it indicates that the connection applied by the shared R-TWT SP is multiple connections; when the aligned flag is set to 0, it indicates that the connection applied by the shared R-TWT SP is a single connection.
[0055] Optionally, under each connection to which the shared R-TWT SP is applied, there is overlapping time between times indicated by the shared R-TWT SP.
[0056] Optionally, when the connection to which the shared R-TWT SP is applied is a single connection, the time offset of the shared R-TWT SP under the applied connection can be set. When the connection to which the shared R-TWT SP is applied is multiple connections, the time offset of the shared R-TWT SP under each applied connection can be set.
[0057] Optionally, the time offset time under each connection applied by the shared R-TWT SP can be the same or different, that is, the time offset time under different connections can be independent of each other; for example, when the multiple connections applied by the shared R-TWT SP include Link1 and Link2, the time offset time under Link1 and the time offset time under Link2 can be the same or different.
[0058] Optionally, when the time offset times under each connection applied by the shared R-TWT SP are the same, only one time offset time may be set, which can save data transmission bandwidth.
[0059] Optionally, when the low-latency service data transmitted within the shared R-TWT SP is periodic service data, AP1 needs to periodically broadcast the first wireless frame to ensure that the service data transmission between AP1 and STA will not affect the communication of the low-latency service within the shared R-TWT SP of the shared AP.
[0060] Step 2: AP1 broadcasts the first wireless frame to STAs.
[0061] Optionally, AP1 may broadcast the first wireless frame to the STA via a beacon frame or a probe response frame, an association response frame, or a reassociation response frame, wherein the probe response frame may be an unsolicited probe response frame.
[0062] Step 3: After receiving the first wireless frame, the STA determines the shared R-TWT SP and TSF information. Based on the shared R-TWT SP and TSF information, the STA determines the actual time of sharing the R-TWT SP through the first AP in combination with the following methods, and further determines the communication method between the STA and AP1:
[0063] Step 3-1: The STA determines the number of shared APs based on the shared AP identification information in the shared R-TWT SP.
[0064] Step 3-2: For each shared AP, the STA determines the connection applied by the shared R-TWT SP based on the aligned flag in the shared R-TWT SP information corresponding to the shared AP.
[0065] Step 3-3: For each shared AP, under each connection applied by the shared R-TWT SP corresponding to the shared AP, determine the time offset time under the connection based on the TSF offset parameter information in the TSF information; and based on the time indicated by the shared R-TWT SP, offset the time offset time under the connection to obtain the actual time of the shared R-TWT SP.
[0066] As in the above example, the time of the shared R-TWT SP received by the STA from AP1 is t1 to t2, and the time offset time t' is t3-t1. Based on the start time t1 of the received shared R-TWT SP, offset t' (that is, add t') to obtain t3. On the basis of t3, add the duration s(t4-t3) indicated by the shared R-TWT SP to obtain t4, and the actual time of the shared R-TWT SP is t3 to t4, which is consistent with the shared R-TWT SP generated when the shared R-TWT SP is directly broadcast by the shared AP. The synchronization of the two shared R-TWT SPs generated when the time indicated by the shared R-TWT SP is broadcast by AP1 and the shared AP respectively is achieved.
[0067] Step 3-4: During the actual time of sharing the R-TWT SP under each of the above connections, the STA and AP1 do not communicate.
[0068] In this way, STA can determine the actual time of sharing R-TWT SP under each connection applied by each R-TWT SP through the TSF information in the first wireless frame received and the shared R-TWT SP, thereby realizing the synchronization of the two shared R-TWT SPs generated when the time indicated by the shared R-TWT SP is broadcast by AP1 and the shared AP respectively. And during the actual time of sharing R-TWT SP, it is ensured that STA does not communicate with AP1, so as to avoid interference with the low-latency service communication within the actual time of sharing R-TWT SP. In this way, the service data transmission between AP1 and STA is guaranteed, and the communication of low-latency services within the shared R-TWT SP is guaranteed, thereby improving data transmission efficiency and spectrum utilization.
[0069] As shown in FIG3 , an embodiment of the present disclosure provides a low-latency service transmission method, which can optionally be applied to a first access point (AP) device. Optionally, in an embodiment of the present disclosure, all APs, such as the first AP, the second AP, AP1, AP2, and AP3, can be collectively referred to as APs. An AP is, for example, a device with a wireless to wired bridging function, and the AP is responsible for extending the services provided by the wired network to the wireless network. A station device (STA), for example, an electronic device with a wireless network access function, provides a frame delivery service to enable information to be transmitted.
[0070] Optionally, AP may include three forms, such as soft AP (or soft AP MLD), non-simultaneous transmitting and receiving (NSTR) mobile AP (or NSTR mobile AP MLD; mobile AP is mobile AP; AP MLD is Access Point Multi-Link Device, multiple connection access point device) and regular AP (or regular AP MLD; regular AP is regular AP), where a regular AP is, for example, a router.
[0071] Referring to FIG3 , the method may include the following steps:
[0072] Step 301: Determine a first radio frame; wherein the first radio frame includes a second R-TWT SP of a second AP and time synchronization parameter TSF information of the second AP;
[0073] Step 302: Send a first radio frame to instruct the station device STA to determine the time of the second R-TWT SP according to the above TSF information and the second R-TWT SP, and not communicate with the first AP during the time of the second R-TWT SP.
[0074] In the disclosed embodiment, the second AP is the shared AP mentioned above. This is for illustration only, indicating the AP corresponding to the second R-TWT SP. The number of the second APs can be singular or plural, without limitation. For example, when the number of the second APs is plural, the second APs can include AP2 and AP3.
[0075] Optionally, the first AP and the second AP may be attached APs of the same or different AP MLDs, or may be different AP MLDs or independent APs, without limitation herein. Optionally, the first AP is attached to the first AP MLD, and the second AP is attached to the second AP MLD. The first AP may be within a certain location range or coverage range from the second AP, so that the first AP can obtain parameter information of the second AP, for example, the first AP can obtain the second R-TWT SP of the second AP.
[0076] The time synchronization parameter TSF information can be used to indicate that when the R-TWT SP is sent to other APs other than the AP indicated by the R-TWT SP, the actual time indicated by the R-TWT SP needs to be synchronized under different APs.
[0077] The TSF information may specifically include time deviation information between the actual start times of the two second R-TWT SPs when the times indicated by the second R-TWT SP are directly sent by the second AP and the first AP, respectively. Correspondingly, the time length indicated by the second R-TWT SP remains unchanged, and the TSF information may also indicate: time deviation information between the actual end times of the two second R-TWT SPs when the times indicated by the second R-TWT SP are directly sent by the second AP and the first AP, respectively.
[0078] In the embodiment of the present disclosure, the time offset information between the actual start times of two second R-TWT SPs generated by TSF information indication is taken as an example for description.
[0079] Optionally, in an embodiment of the present disclosure, the first wireless frame includes a beacon frame or a probe response frame, an association response frame, and a reassociation response frame. The probe response frame may be an unsolicited probe response frame.
[0080] Optionally, the first AP may send the first wireless frame to the STA, instructing the STA to determine the time of the second R-TWT SP (i.e., the time when the service transmission is actually performed within the second R-TWT SP) based on the TSF information and the second R-TWT SP. For example, the STA may be instructed to add the time deviation information indicated by the TSF information to the start time indicated by the second R-TWT SP to obtain the actual start time of the second R-TWT SP, and then add the duration indicated by the second R-TWT SP to the actual start time of the second R-TWT SP to obtain the actual time of the second R-TWT SP. That is, the time of the second R-TWT SP may be obtained by adding the time deviation information indicated by the TSF information to the time indicated by the second R-TWT SP, thereby realizing synchronization between the time generated when the second R-TWT SP is shared by the first AP and the time generated when the second R-TWT SP is shared by the second AP.
[0081] Instruct the STA not to communicate with the first AP during the second R-TWT SP, that is, instruct the STA not to perform service data transmission with the first AP during the second R-TWT SP. That is, when the service data transmission time (i.e., data communication time) between the first AP and the STA overlaps with the time of the second R-TWT SP, the service data transmission between the first AP and the STA is stopped.
[0082] As an example, assuming that the first AP communicates with the STA within the time of the first R-TWT SP, the actual communication duration is 1ms (millisecond), and there is at least partial overlap between the actual communication duration and the time of the second R-TWT SP, for example, the overlap time is 0.5ms, then the first AP will instruct the STA to stop transmitting service data within the time of the first R-TWT SP.
[0083] In this way, by determining and sending the first radio frame through the first AP, the STA that receives the first radio frame can determine the actual time when the second R-TWT SP is shared by the first AP (i.e., the time of the second R-TWT SP) corresponding to the time when the second R-TWT SP is shared by the second AP based on the TSF information in the first radio frame and the second R-TWT SP, that is, the time generated when the second R-TWT SP is shared by the first AP is synchronized with the time generated when the second R-TWT SP is shared by the second AP. And not communicating with the first AP during the time of the second R-TWT SP can avoid interference with the low-latency service communication within the second R-TWT SP when the STA communicates with the first AP. In this way, both the service data transmission between the first AP and the STA and the communication of the low-latency service within the second R-TWT SP are guaranteed, thereby improving data transmission efficiency and spectrum utilization.
[0084] Optionally, the first radio frame includes identification information of the second AP;
[0085] The identification information may include at least one of a MAC address, an AP MLD address of an AP MLD to which the second AP belongs, and a BSS color.
[0086] Optionally, the first AP may set a specific field in the first wireless frame, and set identification information of the second AP through the field.
[0087] Optionally, when there are multiple second APs, for each second AP, after setting the identification information of the second AP, the set identification information of the second AP can be associated with the second R-TWT SP of the second AP and the TSF information corresponding to the second AP to form the R-TWT SP information of each second AP.
[0088] In this implementation, by setting the identification information of the second AP in the first wireless frame, when the second AP includes at least two APs, the R-TWT SP and TSF information corresponding to each AP can be determined through the identification information of each AP.
[0089] Optionally, the first radio frame includes first identification information, where the first identification information indicates a connection applied by the second R-TWT SP;
[0090] Among them, the first identification information indicates that the applied connection includes multiple connections, and the first radio frame also includes TSF offset parameter information of the second R-TWT SP in each connection.
[0091] Optionally, in the first wireless frame, an aligned flag can be set. For example, the aligned flag can be carried in the Broadcast TWT Parameter Set (Broadcast Target Wake-up Time Parameter Set) field of the R-TWT SP information. The aligned flag is used as the first identification information. By setting the aligned flag to a different value, the connection applied by the second R-TWT SP is indicated.
[0092] For example, when the aligned flag is set to 1, it indicates that the connection applied by the second R-TWT SP is multiple connections; when the aligned flag is set to 0, it indicates that the connection applied by the second R-TWT SP is a single connection.
[0093] Optionally, there is overlapping time between the times indicated under each connection to which the second R-TWT SP applies.
[0094] Optionally, when the connection applied by the second R-TWT SP is a single connection, the TSF information may include TSF offset parameter information of the second R-TWT SP under the connection, that is, TSF information. When the connection applied by the second R-TWT SP is multiple connections, the TSF offset parameter information of the second R-TWT SP under each applied connection may be set, that is, the TSF information includes the TSF offset parameter information of the second R-TWT SP under each applied connection.
[0095] The TSF offset parameter information indicates, for each connection to which the second R-TWT SP is applied, time deviation information between the time when the second R-TWT SP under the connection is shared by the first AP and the time when the second R-TWT SP under the connection is shared by the second AP.
[0096] Optionally, the TSF offset parameter information under each connection applied by the second R-TWT SP may be the same or different, that is, the TSF offset parameter information under different connections may be independent of each other; for example, when the multiple connections applied by the second R-TWT SP include Link1 and Link2, the TSF offset parameter information under Link1 may be the same as or different from the TSF offset parameter information under Link2.
[0097] Optionally, when the TSF offset parameter information under each connection applied by the second R-TWT SP is the same, only one TSF offset parameter may be set in the first radio frame, thereby saving data transmission bandwidth.
[0098] Optionally, the first radio frame further includes a time offset between the first AP and the second AP;
[0099] The time of the second R-TWT SP includes: the time after the time offset time identified by the second R-TWT SP.
[0100] Optionally, the TSF information or TSF offset parameter information may specifically include the time offset between the first AP and the second AP. The time offset is the offset between the time actually indicated by the second R-TWT SP when broadcasting directly through the first AP and directly through the second AP.
[0101] Optionally, when the connection applied by the second R-TWT SP is a single connection, the time of the second R-TWT SP under the connection is the time after the time offset time of the time offset identified by the second R-TWT SP. When the connection applied by the second R-TWT SP is multiple connections, the time of the second R-TWT SP under each connection is the time after the time offset time of the time offset identified by the second R-TWT SP under the connection.
[0102] In the above manner, the time of the second R-TWT SP in each connection applied by the second R-TWT SP can be determined according to the different connections applied by the second R-TWT SP.
[0103] Optionally, the sending of the first radio frame may include:
[0104] The first radio frame is sent periodically; wherein the service transmitted in the second R-TWT SP is a periodic service.
[0105] Optionally, when the low-latency service data transmitted within the second R-TWT SP is periodic service data, the first AP needs to periodically broadcast the first wireless frame to ensure that the STA that receives the first wireless frame will not affect the communication of the periodic low-latency service transmitted within the second R-TWT SP of the second AP when transmitting service data with the first AP.
[0106] The present disclosure provides a low-latency service transmission method, which is applied to a first access point device AP. The method specifically includes the following steps:
[0107] Determine a first radio frame; wherein the first radio frame includes a second R-TWT SP of the second AP and time synchronization parameter TSF information of the second AP;
[0108] A first radio frame is sent to instruct the station device STA to determine the time of the second R-TWT SP according to the above TSF information and the second R-TWT SP, and not to communicate with the first AP during the time of the second R-TWT SP.
[0109] Optionally, the first radio frame includes identification information of the second AP;
[0110] The identification information may include at least one of a MAC address, an AP MLD address of an AP MLD to which the second AP belongs, and a BSS color.
[0111] Optionally, the first radio frame includes first identification information, where the first identification information indicates a connection applied by the second R-TWT SP;
[0112] Among them, the first identification information indicates that the applied connection includes multiple connections, and the first radio frame also includes TSF offset parameter information of the second R-TWT SP in each connection.
[0113] Optionally, the first radio frame further includes a time offset between the first AP and the second AP;
[0114] The time of the second R-TWT SP includes: the time after the time offset time identified by the second R-TWT SP.
[0115] Optionally, the sending of the first radio frame may include:
[0116] The first radio frame is sent periodically; wherein the service transmitted in the second R-TWT SP is a periodic service.
[0117] In this way, by determining and sending the first radio frame through the first AP, the STA that receives the first radio frame can determine the actual time when the second R-TWT SP is shared by the first AP (i.e., the time of the second R-TWT SP) corresponding to the time when the second R-TWT SP is shared by the second AP based on the TSF information in the first radio frame and the second R-TWT SP, that is, the time generated when the second R-TWT SP is shared by the first AP is synchronized with the time generated when the second R-TWT SP is shared by the second AP. And not communicating with the first AP during the time of the second R-TWT SP can avoid interference with the low-latency service communication within the second R-TWT SP when the STA communicates with the first AP. In this way, both the service data transmission between the first AP and the STA and the communication of the low-latency service within the second R-TWT SP are guaranteed, thereby improving data transmission efficiency and spectrum utilization. The embodiment of the present disclosure provides a transmission method for low-latency service data.
[0118] 4 , an embodiment of the present disclosure provides a low-latency service transmission method. Optionally, the method may be applied to a station device STA. The method may include the following steps:
[0119] Step 401: Receive a first wireless frame sent by a first access point device AP; wherein the first wireless frame includes a second R-TWT SP of a second AP and TSF information of the second AP;
[0120] Step 402: Determine the time of the second R-TWT SP according to the TSF information and the second R-TWT SP, and do not communicate with the first AP during the time of the second R-TWT SP.
[0121] In the disclosed embodiment, the second AP is the shared AP mentioned above. This is for illustration only, indicating the AP corresponding to the second R-TWT SP. The number of the second APs can be singular or plural, without limitation. For example, when the number of the second APs is plural, the second APs can include AP2 and AP3.
[0122] Optionally, the first AP and the second AP may be attached APs of the same or different AP MLDs, or may be different AP MLDs or independent APs, without limitation herein. Optionally, the first AP is attached to the first AP MLD, and the second AP is attached to the second AP MLD. The first AP may be within a certain location range or coverage range from the second AP, so that the first AP can obtain parameter information of the second AP, for example, the first AP can obtain the second R-TWT SP of the second AP.
[0123] The time synchronization parameter TSF information can be used to indicate that when the R-TWT SP is sent to other APs other than the AP indicated by the R-TWT SP, the actual time indicated by the R-TWT SP needs to be synchronized under different APs.
[0124] The TSF information may specifically include time deviation information between the actual start times of two second R-TWT SPs generated when the time indicated by the second R-TWT SP is directly sent by the second AP and the first AP, respectively. Correspondingly, the time length indicated by the second R-TWT SP remains unchanged, and the TSF information may also indicate: time deviation information between the actual end times of two second R-TWT SPs generated when the time indicated by the second R-TWT SP is directly sent by the second AP and the first AP, respectively. In the embodiment of the present disclosure, the time deviation information between the actual start times of two second R-TWT SPs generated by the TSF information indication is used as an example for explanation.
[0125] Optionally, in an embodiment of the present disclosure, the first wireless frame includes a beacon frame or a probe response frame, an association response frame, and a reassociation response frame. The probe response frame may be an unsolicited probe response frame.
[0126] Optionally, when the STA determines the time of the second R-TWT SP based on the TSF information and the second R-TWT SP, for example, the STA may add the time offset information indicated by the TSF information to the start time indicated by the second R-TWT SP to obtain the actual start time of the second R-TWT SP, and then add the duration indicated by the second R-TWT SP to the actual start time of the second R-TWT SP to obtain the actual time of the second R-TWT SP. That is, the time of the second R-TWT SP may be obtained by adding the time offset information indicated by the TSF information to the time indicated by the second R-TWT SP, that is, the time when the second R-TWT SP is shared by the first AP actually corresponds to the time when the second R-TWT SP is shared by the second AP.
[0127] The STA does not communicate with the first AP during the second R-TWT SP period, that is, the STA does not perform service data transmission with the first AP during the second R-TWT SP period. That is, when the service data transmission period (i.e., data communication period) between the first AP and the STA overlaps with the second R-TWT SP period, service data transmission between the STA and the first AP is stopped.
[0128] As an example, assuming that the first AP communicates with the STA within the time of the first R-TWT SP, the actual communication duration is 1ms (millisecond), and there is at least partial overlap between the actual communication duration and the time of the second R-TWT SP, for example, the overlap time is 0.5ms, then the STA will stop transmitting business data with the first AP within the time of the first R-TWT SP.
[0129] In this way, the STA that receives the first wireless frame can specifically determine the actual time when the second R-TWT SP is shared by the first AP (i.e., the time of the second R-TWT SP) corresponding to the time when the second R-TWT SP is shared by the second AP based on the TSF information in the first wireless frame and the second R-TWT SP, and will not communicate with the first AP during the time of the second R-TWT SP, that is, the time generated when the second R-TWT SP is shared by the first AP is synchronized with the time generated when the second R-TWT SP is shared by the second AP. This can avoid interference with the low-latency service communication within the second R-TWT SP when the STA communicates with the first AP. This ensures both the service data transmission between the first AP and the STA and the communication of the low-latency service within the second R-TWT SP, thereby improving data transmission efficiency and spectrum utilization.
[0130] Optionally, the first radio frame includes identification information of the second AP;
[0131] The identification information includes at least one of a MAC address, an AP MLD address of an AP MLD to which the second AP belongs, and a BSS color.
[0132] Optionally, the STA may determine the identification information of the second AP according to a specific field set in the first radio frame.
[0133] Optionally, when there is identification information of multiple second APs in a specific field, it can be determined that the number of second APs includes multiple ones, and further based on the R-TWT SP information associated with the identification information of each second AP, the second R-TWT SP of the second AP and the TSF information corresponding to the second AP can be determined.
[0134] In this implementation, by determining the identification information of the second AP in the first wireless frame, the specific number of second APs can be determined, and based on the identification information of each second AP, the second R-TWT SP of each AP and the TSF information corresponding to the second AP can be determined.
[0135] Optionally, the first radio frame includes first identification information, where the first identification information indicates a connection applied by the second R-TWT SP;
[0136] Among them, the first identification information indicates that the applied connection includes multiple connections, and the first radio frame also includes TSF offset parameter information of the second R-TWT SP in each connection.
[0137] Optionally, the STA can determine the first identification information by the aligned identification bit carried in the Broadcast TWT Parameter Set (broadcast target wake-up time parameter set) field of the R-TWT SP information in the first wireless frame. Specifically, the connection applied by the second R-TWT SP can be determined based on the value of the aligned identification bit.
[0138] For example, when the aligned flag is set to 1, it indicates that the connection applied by the second R-TWT SP is multiple connections; when the aligned flag is set to 0, it indicates that the connection applied by the second R-TWT SP is a single connection.
[0139] Optionally, when the connection applied by the second R-TWT SP is a single connection, it can be determined that the TSF information includes the TSF offset parameter information of the second R-TWT SP under the connection. When the connection applied by the second R-TWT SP is multiple connections, it can be determined that the TSF information includes the TSF offset parameter information of the second R-TWT SP under each applied connection, and then the TSF offset parameter information of the second R-TWT SP under each applied connection is determined.
[0140] The TSF offset parameter information indicates, for each connection to which the second R-TWT SP is applied, time deviation information between the time when the second R-TWT SP under the connection is shared by the first AP and the time when the second R-TWT SP under the connection is shared by the second AP.
[0141] Optionally, the TSF offset parameter information under each connection applied by the second R-TWT SP may be the same or different, that is, the TSF offset parameter information under different connections may be independent of each other; for example, when the multiple connections applied by the second R-TWT SP include Link1 and Link2, the TSF offset parameter information under Link1 may be the same as or different from the TSF offset parameter information under Link2.
[0142] Optionally, if the aligned flag is set to 1 and only one TSF offset parameter is set in the first radio frame, it can be determined that the TSF offset parameter information under each connection applied by the second R-TWT SP is the same.
[0143] Optionally, the determining of the time of the second R-TWT SP according to the TSF information and the second R-TWT SP may include:
[0144] Obtain a time offset in the first wireless frame; the time offset is the time offset between the first AP and the second AP;
[0145] The time for determining the second R-TWT SP is the time after the time offset identified by the second R-TWT SP.
[0146] Optionally, the TSF information or TSF offset parameter information may specifically include the time offset between the first AP and the second AP. The time offset is the offset between the time actually indicated by the second R-TWT SP when broadcasting directly through the first AP and directly through the second AP.
[0147] Optionally, in the case where the connection applied by the second R-TWT SP is a single connection, the STA can obtain the time offset time in the first wireless frame, and determine that the time of the second R-TWT SP under the connection is: the time after the time offset time identified by the second R-TWT SP. In the case where the connection applied by the second R-TWT SP is multiple connections, for each connection, the STA can obtain the time offset time of the second R-TWT SP under the connection in the first wireless frame, and determine that the time of the second R-TWT SP under the connection is: the time after the time offset time identified by the second R-TWT SP under the connection.
[0148] In the above manner, the STA can determine the time of the second R-TWT SP in each connection applied by the second R-TWT SP according to different connections applied by the second R-TWT SP.
[0149] Optionally, the receiving of the first wireless frame sent by the first access point device AP may include:
[0150] Periodically receive a first radio frame sent by the first AP; wherein the service transmitted in the second R-TWT SP is a periodic service.
[0151] Optionally, when the low-latency service data transmitted within the second R-TWT SP is periodic service data, the STA periodically receives the first wireless frame sent by the first AP to avoid transmitting service data with the first AP within the time of the second R-TWT SP determined according to the periodically received first wireless frame, thereby avoiding interfering with the communication of the periodic low-latency service transmitted within the second R-TWT SP of the second AP.
[0152] An embodiment of the present disclosure provides a low-latency service transmission method. Optionally, the method may be applied to a station device (STA). The method may include the following steps:
[0153] Receive a first wireless frame sent by a first access point device AP; wherein the first wireless frame includes a second R-TWT SP of a second AP and TSF information of the second AP;
[0154] The time of the second R-TWT SP is determined according to the TSF information and the second R-TWT SP, and no communication is performed with the first AP during the time of the second R-TWT SP.
[0155] Optionally, the first radio frame includes identification information of the second AP;
[0156] The identification information includes at least one of a MAC address, an AP MLD address of an AP MLD to which the second AP belongs, and a BSS color.
[0157] Optionally, the first radio frame includes first identification information, where the first identification information indicates a connection applied by the second R-TWT SP;
[0158] Among them, the first identification information indicates that the applied connection includes multiple connections, and the first radio frame also includes TSF offset parameter information of the second R-TWT SP in each connection.
[0159] Optionally, the determining of the time of the second R-TWT SP according to the TSF information and the second R-TWT SP may include:
[0160] Obtain a time offset in the first wireless frame; the time offset is the time offset between the first AP and the second AP;
[0161] The time for determining the second R-TWT SP is the time after the time offset identified by the second R-TWT SP.
[0162] Optionally, the receiving of the first wireless frame sent by the first access point device AP may include:
[0163] Periodically receive a first radio frame sent by the first AP; wherein the service transmitted in the second R-TWT SP is a periodic service.
[0164] In this way, the STA that receives the first wireless frame can determine the actual time when the second R-TWT SP is shared by the first AP (i.e., the time of the second R-TWT SP) corresponding to the time when the second R-TWT SP is shared by the second AP based on the TSF information in the first wireless frame and the second R-TWT SP, that is, the time generated when the second R-TWT SP is shared by the first AP is synchronized with the time generated when the second R-TWT SP is shared by the second AP. And not communicating with the first AP during the time of the second R-TWT SP can avoid interference with the low-latency service communication within the second R-TWT SP when the STA communicates with the first AP. In this way, both the service data transmission between the first AP and the STA and the communication of the low-latency service within the second R-TWT SP are guaranteed, thereby improving data transmission efficiency and spectrum utilization.
