[0134] The various embodiments of the present disclosure can be applied to a wireless local area network (WLAN), such as a local area network that adopts the 802.11 series of protocols. In a WLAN, a basic service set (BSS) is a basic component of a WLAN. A BSS network is composed of station devices with certain associations within a specific coverage area. One scenario of association is that stations communicate directly with each other in an ad hoc network, which is called an independent basic service set (IBSS). Another more common scenario is that in a BSS network, there is only one central station with a dedicated BSS management function, which is called an access point device, and other stations in the BSS network that are not APs are called terminals, also called non-AP STAs. APs and non-AP STAs are collectively referred to as STAs. When describing STAs, there is no need to distinguish between APs and non-AP STAs. In the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are farther away from it, and the two are hidden nodes of each other.

[0135] In 802.11be, there is a TXOP sharing mechanism, that is, after the AP obtains the TXOP, it will share the TXOP with its associated STA (at most one) for uplink non-TB UL PPDU transmission (non-triggered uplink physical layer protocol data unit transmission, where non-TB means non-triggered based, UL means up-link, and PPDU means Physical Protocol Data Unit) or P2P (Peer to Peer) transmission.

[0136] Optionally, the access point device can transmit data with the station device within a transmission opportunity (TXOP). In the disclosed embodiments, there are no restrictions on the initiator (TXOP holder) and responder (TXOP responder) of the TXOP. For example, the access point device can act as a TXOP holder, obtain a TXOP, and send data to the station device within the TXOP; or the station device can act as a TXOP holder, obtain a TXOP, and send data to the access point device within the TXOP.

[0137] In UHR, when a communication process of non-low-latency service data is carried out in a TXOP, it can be indicated that there is low-latency service data to be transmitted by carrying an identification bit (for example, pre-emption, i.e., pre-clearance identification) in the transmitted PPDU. Then: the device that transmits or receives non-low-latency service data needs to update its NAV setting to busy when the low-latency service is transmitted, and the duration is the transmission duration of the low-latency service data. However, after the low-latency service data transmission is completed, when the device that transmits or receives non-low-latency service data updates its NAV in the TXOP to continue transmitting or receiving non-low-latency service, it needs to be defined. The embodiments of the present disclosure are respectively combined with Figures 2a and 2c, taking the access point device 101 as the sender of low-latency service data as an example, and, combined with Figures 2b and 2d, taking the access point device 101 as the receiver of low-latency service data as an example, to define this.

[0138] Figure 2a is one of the interactive diagrams of a communication method according to an embodiment of the present disclosure. As shown in Figure 2a, through steps 201 to 206, it is possible to define when to update the NAV of the first station device 102 after completing the transmission of the low-latency service data in the TXOP to continue transmitting or receiving non-low-latency services with the first station device 102, taking the access point device 101 as the sender of the low-latency service data as an example. The above method includes:

[0139] In step 201 , the access point device 101 determines a first radio frame, wherein the first radio frame identifies whether the access point device 101 completes sending first low-latency service data to the first station device 102 within a first TXOP (transmission opportunity) of the access point device 101 .

[0140] Optionally, the first radio frame may be the last data frame of the first low-latency service data, for example, the first radio frame may be a PPDU (physical Protocol Data Unit) frame.

[0141] Optionally, in some embodiments, the MAC frame header of the first radio frame includes a first identification bit;

[0142] The first flag is set to a first parameter value, indicating that the access point device 101 has completed sending the first low-latency service data.

[0143] Optionally, the first identification bit may be a more data bit in an FC field (Frame Control, frame control field) of a MAC frame header of the first radio frame.

[0144] Optionally, the parameter value of the first flag bit can be 0 or 1. The first parameter value can be set to 0, that is, when the first flag bit is set to 0, it indicates that the access point device 101 has completed the transmission of the first low-latency service data (that is, there is no transmission of downlink low-latency service data frames in the first TXOP). The second parameter value can be set to 1, that is, when the first flag bit is set to 1, it indicates that the access point device 101 has not completed the transmission of the first low-latency service data (that is, there is still transmission of downlink low-latency service data frames in the first TXOP).

[0145] As an example, when the access point device 101 sends the last frame of data of the first low-latency service data to the first site device 102, the more data bit of the FC field of the MAC frame header of the PPDU frame can be set to 0 to indicate that the access point device 101 has completed the sending of the first low-latency service data.

[0146] Step 202 : The access point device 101 sends the first radio frame to the first station device 102 .

[0147] In an embodiment of the present disclosure, the access point device uses a first radio frame identifier to indicate whether, within a first TXOP of the access point device, the access point device has completed sending the first low-latency service data to the first site device and sent the first radio frame to the first site device. In this way, the first site device can determine whether the access point device has completed sending the first low-latency service data and the time when the access point device completes sending the first low-latency service data. As a result, when the access point device completes sending the first low-latency service data, the first site device can continue to transmit non-low-latency service data with the access point device.

[0148] Step 203 , after receiving the first low-latency service data, the first site device 102 generates a confirmation frame for the first low-latency service data, indicating that the first site device 102 has received the first low-latency service data, and feeds back the confirmation frame to the access point device 101 .

[0149] Optionally, when the first low-latency service data is an independent data frame, the confirmation frame for the first low-latency service data can be ACK (acknowledgement frame); when the first low-latency service data is multiple consecutive data frames, the confirmation frame for the first low-latency service data can be BA (block ACK, block confirmation frame).

[0150] In step 204, the access point device 101 determines a second radio frame, wherein the second radio frame indicates that the access point device 101 releases the remaining duration of the first TXOP after the first low-latency service data is sent.

[0151] Optionally, the second wireless frame can be a notification frame or a low-latency service occupancy release frame, and the second wireless frame can be used to indicate that the access point device 101 releases the remaining duration of the first TXOP after the first low-latency service data is sent.

[0152] Step 205 : The access point device 101 sends the second radio frame to the first station device 102 .

[0153] Optionally, after receiving the second wireless frame, the first site device 102 can set the NAV of the first site device 102 to idle according to the remaining duration of the first TXOP, and the duration is the remaining duration of the first TXOP, so as to re-access the channel and transmit non-low-latency service data with the access point device 101 within the remaining duration of the first TXOP.

[0154] In an embodiment of the present disclosure, after the first site device feeds back a confirmation frame for the first low-latency service data to the access point device, a second radio frame is determined, and the access point device releases the remaining duration of the first TXOP after the first low-latency service data is sent, using the second radio frame identifier; in this way, the first site device can determine the remaining duration of the first TXOP after the first low-latency service data is sent, and continue to transmit non-low-latency service data with the access point device within the remaining duration of the first TXOP.

[0155] Step 206 : The access point device 101 transmits non-low-latency service data to the first site device 102 .

[0156] Optionally, the first station device 102 may transmit non-low-latency service data to the access point device 101 after receiving the second radio frame and after an interval of SIFS (Short Interframe Space).

[0157] The communication method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, step 201 can be implemented as an independent embodiment, step 202 can be implemented as an independent embodiment, step 203 can be implemented as an independent embodiment, step 204 can be implemented as an independent embodiment, step 205 can be implemented as an independent embodiment, and step 206 can be implemented as an independent embodiment; the combination of step 201 and step 202 can be implemented as an independent embodiment, the combination of step 204 and step 205 can be implemented as an independent embodiment, the combination of step 203, step 204 and step 205 can be implemented as an independent embodiment, the combination of step 201, step 202 and step 203 can be implemented as an independent embodiment, the combination of step 201, step 202, step 203, step 204 and step 205 can be implemented as an independent embodiment, and the combination of step 201, step 202, step 203, step 204 and step 205 can be implemented as an independent embodiment, but is not limited thereto.

[0158] In some embodiments, reference may be made to other optional implementations described before or after the description corresponding to FIG. 2 a .

[0159] FIG2b is a second interactive diagram of a communication method according to an embodiment of the present disclosure. As shown in FIG2b, through steps 207 to 212, it is possible to define when, after receiving the low-latency service data in the TXOP, the NAV of the second site device 102 is updated to continue transmitting or receiving non-low-latency services with the second site device 102, using the access point device 101 as the receiver of the low-latency service data as an example. The above method includes:

[0160] Step 207 : The second site device 103 determines a third radio frame; wherein the third radio frame identifies whether the second site device 103 completes sending the second low-latency service data to the access point device 101 within the second TXOP of the access point device 101 .

[0161] Optionally, the third radio frame may be the last data frame of the third low-latency service data, for example, the third radio frame may be a PPDU frame.

[0162] Optionally, in some embodiments, the MAC frame header of the third radio frame includes a second identification bit;

[0163] The second flag is set to a third parameter value, indicating that the second site device 103 has completed sending the second low-latency service data.

[0164] Optionally, the second identification bit may be a more data bit in an FC field (Frame Control, frame control field) of a MAC frame header of the third radio frame.

[0165] Optionally, the parameter value of the second flag bit can be 0 or 1. Among them, the third parameter value can be set to 0, that is, when the second flag bit is set to 0, it indicates that the second site device 103 has completed the transmission of the second low-latency service data (that is, within the second TXOP, there is no transmission of uplink low-latency service data frames). The fourth parameter value can be set to 1, that is, when the second flag bit is set to 1, it indicates that the second site device 103 has not completed the transmission of the second low-latency service data (that is, within the second TXOP, there is still transmission of uplink low-latency service data frames).

[0166] As an example, when the second site device 103 sends the last frame of data of the second low-latency service data to the access point device 101, the more data bit of the FC domain of the MAC frame header of the PPDU frame can be set to 0 to indicate that the second site device 103 has completed the sending of the second low-latency service data.

[0167] The optional implementation of step 207 can refer to the optional implementation of step 201 in FIG. 2 and other related parts in the embodiment involved in FIG. 2 , which will not be described in detail here.

[0168] Step 208 : The second station device 103 sends a third radio frame to the access point device 101 .

[0169] The optional implementation of step 208 can refer to the optional implementation of step 202 in FIG. 2 and other related parts in the embodiment involved in FIG. 2 , which will not be described in detail here.

[0170] In an embodiment of the present disclosure, the second site device sends a third radio frame to the access point device, and the third radio frame identifies whether the second site device has completed sending the second low-latency service data to the access point device within the second TXOP of the access point device. In this way, the access point device can determine whether the second site device has completed sending the second low-latency service data to the access point device and the time when the second site device completes sending the second low-latency service data by receiving the third radio frame sent by the second site device. Therefore, when the second site device completes sending the second low-latency service data, the access point device can continue to transmit non-low-latency service data with the second site device.

[0171] Step 209 : The access point device 101 feeds back an acknowledgment frame for the second low-latency service data to the second site device 103 .

[0172] Optionally, when the second low-latency service data is an independent data frame, the confirmation frame for the second low-latency service data may be an ACK; when the second low-latency service data is multiple consecutive data frames, the confirmation frame for the second low-latency service data may be a BA frame.

[0173] The access point device 101 may determine an acknowledgment frame for the second low-latency service data according to the number of data frames in the received second low-latency service data, and feed the acknowledgment frame back to the second site device 103 .

[0174] The optional implementation of step 209 can refer to the optional implementation of step 203 in FIG. 2 and other related parts in the embodiment involved in FIG. 2 , which will not be described in detail here.

[0175] Step 210: The access point device 101 determines a fourth radio frame; wherein the fourth radio frame indicates that the access point device 101 releases the second remaining duration of the second TXOP after the second low-latency service data is received.

[0176] Optionally, the fourth radio frame may be a notification frame or a low-latency service occupancy release frame, and the fourth radio frame may indicate that the access point device 101 releases the second remaining duration of the second TXOP after the second low-latency service data is received.

[0177] The optional implementation of step 210 can refer to the optional implementation of step 204 in FIG. 2 and other related parts in the embodiment involved in FIG. 2 , which will not be described in detail here.

[0178] Step 211 : The access point device 101 sends the fourth radio frame to the second station device 103 .

[0179] Optionally, after receiving the second wireless frame, the second site device 103 can set the NAV of the second site device 103 to idle according to the remaining duration of the second TXOP, and the duration is the remaining duration of the second TXOP, so as to re-access the channel and transmit non-low-latency service data with the access point device 101 within the remaining duration of the second TXOP.

[0180] The optional implementation of step 211 can refer to the optional implementation of step 205 in FIG. 2 and other related parts in the embodiment involved in FIG. 2 , which will not be described in detail here.

[0181] Optionally, after the access point device 101 sends back a confirmation frame for the second low-latency service data to the second station device 103, the fourth radio frame is again sent to the station device 103. This can avoid a situation in which, due to factors such as distance and transmit power, the access point device 101 is unable to detect the second station device 103 that is farther away from it in the same BSS network, causing the access point device 101 and the second station device 103 to become each other's hidden nodes. Furthermore, the fourth radio frame indicates that the access point device has released the remaining duration of the second TXOP after receiving the second low-latency service data. In this way, the second station device can determine the remaining duration of the second TXOP after sending the second low-latency service data, and continue to transmit non-low-latency service data with the access point device within the remaining duration of the second TXOP.

[0182] In step 212 , the access point device 101 transmits non-low-latency service data to the second site device 103 .

[0183] Optionally, the second site device 103 may transmit non-low-latency service data to the access point device 101 after receiving the fourth radio frame and after a SIFS interval.

[0184] The optional implementation of step 212 can refer to the optional implementation of step 206 in FIG. 2 and other related parts in the embodiment involved in FIG. 2 , which will not be described in detail here.
