[0148] Figure 2 is an interactive diagram of a low-latency service transmission method according to an embodiment of the present disclosure. As shown in Figure 2, an embodiment of the present disclosure relates to a low-latency service transmission method, the method comprising:

[0149] Step 201: The access point device determines a first radio frame, where the first radio frame indicates first identification information, and the first identification information identifies: a time length information of peer-to-peer (P2P) communication between at least two station devices.

[0150] Assume that the AP has established an initial association with STA1 and STA2, and a TDLS link has been established between STA1 and STA2. During P2P communication, the TXOP sharing mechanism (TXOP stands for transmission opportunity) can be used. The AP shares the TXOP with STA1 for P2P transmission and sends a MU-RTS TXS frame (Multi-User Request Transmission Opportunity Sharing frame) to STA1, instructing STA1 to conduct P2P communication with STA2 over the TDLS link.

[0151] However, with the continuous development of WiFi technology, in order to meet UHR (Ultra-High Reliability) requirements, there may be multiple STAs associated with an AP that need to perform P2P communication. In addition, during P2P communication, low-latency service data may need to be transmitted. To avoid mutual interference between service data transmitted in communication between the AP and the STA and service data transmitted in P2P communication, P2P communication can be performed using the low-latency service transmission method provided in the embodiments of the present disclosure.

[0152] In some embodiments, the first radio frame may be at least one of a beacon frame, a probe response frame, or an unsolicited probe response frame.

[0153] In some embodiments, the at least two station devices include a first station device, a second station device, a third station device, ..., a tenth station device. The access point device establishes an initial association with each of the at least two station devices.

[0154] In some embodiments, the first radio frame may include the communication duration between any two station devices performing P2P communication.

[0155] In some embodiments, the time length information includes at least two of the communication time length, start time, and end time of the P2P communication performed by the station device.

[0156] As an example, if the time length information includes the communication time length and the start time, the end time can be determined by adding the communication time length to the start time. If the time length information includes the communication time length and the end time, the start time can be determined by subtracting the communication time length from the end time. The start and end times can then be used to determine the time period during which the site device conducts P2P communication.

[0157] In the above embodiment, the time period for the site device to perform P2P communication can be determined based on at least two of the communication time length, start time, and end time of the site device performing P2P communication, thereby paving the way for subsequently isolating the time periods corresponding to different communication processes and avoiding cross-interference between transmission services in different communication processes.

[0158] In some embodiments, the first radio frame carries a restricted target wake time R-TWT information element;

[0159] The R-TWT information element includes an R-TWT transmission information R-TWT Traffic Info field;

[0160] The R-TWT Traffic Info field includes the Traffic Info Control subfield;

[0161] The Traffic Info Control subfield includes P2P communication information.

[0162] Among them, the beacon frame or (unsolicited) probe response frame may include an R-TWT information element, and the R-TWT information element may include an R-TWT Traffic Info field. The R-TWT Traffic Info field may include subfields such as Traffic Info Control, Restricted TWT DL TID Bitmap (R-TWT downlink TID bitmap), and Restricted TWT UL TID Bitmap (R-TWT uplink TID bitmap). The various subfields in the R-TWT Traffic Info field can be determined with reference to Table 1.

[0163] Table 1

[0164] As shown in Table 1, the R-TWT information element may include the Traffic Info Control subfield, the Restricted TWT DL TID Bitmap subfield, and the Restricted TWT UL TID Bitmap subfield. Among them, the number of bytes corresponding to the Traffic Info Control subfield is 1, the number of bytes corresponding to the Restricted TWT DL TID Bitmap subfield is 1, and the number of bytes corresponding to the Restricted TWT UL TID Bitmap subfield is 1.

[0165] The Traffic Info Control subfield may include information such as DL TID Bitmap Valid (downlink TID bitmap parameter value), UL TID Bitmap Valid (uplink TID bitmap parameter value), and Reserved. Table 2 may be referenced to determine the various pieces of information in the R-TWT Traffic Info Control field.

[0166] Table 2

[0167] As shown in Table 2, the R-TWT Traffic Info field may include DL TID Bitmap Valid, UL TID Bitmap Valid, and Reserved. DL TID Bitmap Valid includes 1 bit, with the corresponding bit sequence being B0; UL TID Bitmap Valid includes 1 bit, with the corresponding bit sequence being B1; and Reserved includes 6 bits, with the corresponding bit sequence being B2 to B7.

[0168] In some embodiments, P2P communication information may be identified by a bit in Reserved.

[0169] In the above embodiment, the first wireless frame carries the R-TWT information element, the R-TWT information element includes the R-TWT Traffic Info field, the R-TWT Traffic Info field includes the Traffic Info Control subfield, and the Traffic Info Control subfield includes P2P communication information, so that the site device that receives the first wireless frame can accurately parse the P2P communication information in the first wireless frame based on the location information of the P2P communication information in the first wireless frame.

[0170] In some embodiments, the P2P communication information includes:

[0171] TID information;

[0172] Or TID information and link bitmap information;

[0173] The link bitmap information is set to the first parameter value, indicating that P2P communication is performed under the link corresponding to the TID information.

[0174] The TID (traffic identifier) ​​information can be the TID-to-link mapping information negotiated between any two station devices (i.e., STAs) during the process of establishing a P2P link. This TID-to-link mapping information can indicate the type of service transmitted in the P2P link established between the STAs, for example, it can represent low-latency services.

[0175] In some embodiments, the first radio frame may include P2P communication duration information corresponding to each TID information. For example, the AP may broadcast P2P communication duration information corresponding to any TID among TID=0-7.

[0176] In an actual processing process, after the two STAs obtain the TID-to-link mapping information through negotiation, they can report the TID-to-link mapping information to the access point device associated with each STA in the two STAs.

[0177] The access point device can determine the P2P communication information based on the TID information reported by both STAs.

[0178] In some embodiments, the link bitmap information can be 8 bits, 16 bits, 32 bits, etc., and the embodiments of the present disclosure do not limit this. Each bit in the link bitmap information can indicate whether P2P communication can be performed under a P2P link. For example, for each bit in the link bitmap information, when the bit is set to a first parameter value (e.g., 1), it indicates that P2P communication is performed under the link corresponding to the bit, and the service corresponding to the TID information is transmitted under the link. When the bit is set to a third parameter value (e.g., 0), it indicates that P2P communication cannot be performed under the link corresponding to the bit.

[0179] In the above embodiment, by setting TID information in the P2P communication information, or setting TID information and link bitmap information, the site device that receives the first wireless frame can obtain the link that can perform P2P communication according to the P2P communication information, as well as the service type transmitted when performing P2P communication.

[0180] In some embodiments, the R-TWT information element may also include aligned information.

[0181] The aligned information is set to the second parameter value, indicating that the P2P communication is performed under the established P2P link.

[0182] In some embodiments, the aligned information may be a field in an R-TWT information element.

[0183] As an example, when the aligned information is set to the second parameter value, such as 1, it can be indicated that P2P communication can be performed under any link where P2P communication is established.

[0184] In the above embodiment, by setting the aligned information in the R-TWT information element, the station device that receives the first wireless frame can perform P2P communication under any established P2P link according to the aligned information.

[0185] In some embodiments, the time during which the access point device communicates with the station device and the time corresponding to the time length information do not overlap.

[0186] The time during which the access point device communicates with the station device may be a communication cycle between the access point device and the station device, for example, a R-TWT SP (Restricted Target Wake Time Service Time).

[0187] In some embodiments, the non-overlapping of the first time during which the access point device communicates with the station device and the second time corresponding to the time length information may include no overlap between the first time and the second time, or partial overlap between the first time and the second time. For example, when the first time is from t1 to t2 and the second time is from t3 to t4, there is no overlap between the first time and the second time, i.e., t3-t2>0; when there is partial overlap between the first time and the second time, i.e., t1<t3<t2<t4, the overlap between the first time and the second time is t2-t3.

[0188] In the above embodiment, by setting the time for communication between the access point device and the site device and separating the time corresponding to the time length information, interference between the communication services performed by the access point device and the site device and the communication services performed under the P2P link can be avoided, thereby affecting the service communication efficiency and improving spectrum utilization.

[0189] Step 202: The access point device sends a first radio frame to a station device that has established an initial association with the access point device.

[0190] In the above embodiment, the first wireless frame indicates the first identification information, and the first identification information identifies: the time length information of at least two site devices performing P2P communication, and broadcasts the first wireless frame, so that the site device receiving the first wireless frame can perform P2P communication according to the time length information identified by the first identification information, so that the P2P communication service can meet the delay requirements, improve spectrum utilization, and be suitable for UHR requirements.

[0191] Step 203: The first station device determines a second radio frame, where the second radio frame indicates second identification information, and the second identification information identifies request information for requesting the second station device to perform P2P communication with the first station device.

[0192] In some embodiments, the second wireless frame may include a P2P communication request frame.

[0193] In some embodiments, when determining that the second time and the communication time between the first station device and the access point device do not overlap, the first station device may send a P2P communication request frame to the access point device to request P2P communication with the second station device.

[0194] Step 204: The access point device receives the second radio frame and forwards the second radio frame to the second station device.

[0195] Step 205: The second site device determines a third radio frame, where the third radio frame indicates third identification information, and the third identification information identifies: response information to the above request information.

[0196] In some embodiments, the third wireless frame may include a P2P communication response frame.

[0197] The third identification information may indicate that the second site device is allowed to perform P2P communication with the first site device. For example, if the communication time between the first site device and the access point device does not overlap with the second time, the second site device may be allowed to perform P2P communication with the first site device.

[0198] The third identification information may also indicate that the second site device is not allowed to perform P2P communication with the first site device. For example, if the communication time between the first site device and the access point device overlaps with the second time, the second site device is not allowed to perform P2P communication with the first site device.

[0199] Step 206: The access point device receives the third radio frame and forwards the third radio frame to the first station device.

[0200] Step 207: The first site device determines whether to perform P2P communication with the second site device based on the third identification information.

[0201] In the above embodiment, the access point device forwards the P2P communication request frame and the P2P communication response frame between the two STAs (the first station device and the second station device), so that it can be determined whether the requester who initiates the P2P communication request in the STAs can perform P2P communication with the responder of the P2P communication request, so that the requester of the P2P communication request can perform P2P communication with the responder of the P2P communication request after receiving the response information allowing P2P communication.

[0202] Step 208: The access point device determines a fourth radio frame, which includes: first transmit power (tx Power) information for P2P communication between the third site device and the fourth site device; and a P2P link is established between the third site device and the fourth site device.

[0203] In some embodiments, the fourth radio frame may include a MU-RTS TXS frame.

[0204] In some embodiments, the MU-RTS TXS Trigger frame may include transmission power information between STAs that are engaged in P2P communication (for example, a third site device and a fourth site device that have established a P2P link) (hereinafter referred to as "first transmission power information"), information of multiple site devices, and transmission power information of the access point device and the site device associated with it that are communicating (hereinafter referred to as "third transmission power information"), etc.

[0205] The site device information may include an AID (association identifier), that is, an identifier allocated by the access point device to the site device with which the access point device establishes an association.

[0206] In step 209 , the access point device sends a fourth wireless frame to the fifth site device, instructing the fifth site device to perform P2P communication with the sixth site device through the second transmission power; the fifth site device establishes a P2P link with the sixth site device; the second transmission power is different from the first transmission power and the third transmission power.

[0207] Step 210: The fifth site device performs P2P communication with the sixth site device.

[0208] In the above embodiment, by sending the first transmission power information between STAs that are engaged in P2P communication and the second transmission power information that the access point device and its associated site device are communicating to the fifth site device, P2P communication between STAs that have established P2P links (i.e., the fifth site device and the sixth site device) can be effectively triggered, and the fifth site device and the sixth site device can use a second transmission power different from the first transmission power information and the third transmission power information to perform P2P communication, thereby improving spectrum utilization.

[0209] In step 211 , the seventh site device sends a request to send frame (RTS) to the eighth site device; wherein the seventh site device establishes a P2P link with the eighth site device.

[0210] Step 212: The eighth site device sends a Clear to Send (CTS) frame to the seventh site device, triggering the seventh site device to perform P2P communication with the eighth site device.

[0211] Step 213: The seventh site device performs P2P communication with the eighth site device.

[0212] In the above embodiment, any site device among the STAs that have established a P2P link (for example, the seventh site device) can send an RTS frame to the opposite site device among the STAs (for example, the eighth site device), and after receiving the CTS frame sent by the opposite site device, P2P communication between the STAs can be carried out, which can effectively trigger the STAs that have established a P2P link to perform P2P communication.

[0213] In this way, through the above-mentioned low-latency service transmission method, mutual interference between the service data transmitted by the communication between AP and STA and the service data transmitted by P2P communication can be avoided, so that the P2P communication service can meet the latency requirements, improve spectrum utilization, and be suitable for UHR requirements.

[0214] The low-latency service transmission method involved in the embodiments of the present disclosure may include at least one of steps 201 to 212.

[0215] In some embodiments, steps 203 to 207 , steps 208 to 210 , and steps 211 to 213 may be executed in an interchanged order or simultaneously.

[0216] In some embodiments, any combination of steps 203 to 207, steps 208 to 210, and steps 211 to 213 are optional, and one or more of these combination steps may be omitted or replaced in different embodiments.
