[0098] FIG1 is a schematic diagram showing the architecture of a communication system according to an embodiment of the present disclosure.

[0099] As shown in FIG1 , a communication system 100 includes a source device (which may be a Station, STA or Access Point, AP) 101 , a relay device (Relay STA) 102 , and a target device 103 .

[0100] In some embodiments, the source device 101 or the target device 103 can be an access point for a mobile terminal to enter a wired network. The AP is equivalent to a bridge connecting a wired network and a wireless network. Its main function is to connect various wireless network clients together and then connect the wireless network to the Ethernet. Specifically, the AP can be a terminal device or a network device with a wireless fidelity chip. Optionally, the AP can support multiple WLAN standards such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b and 802.11a, 802.11bf, 802.11bn, and support the next generation 802.11 protocol, but is not limited to this.

[0101] In some embodiments, the source device 101, the relay device 102, or the target device 103 may be, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports WiFi communication. Optionally, the wireless communication terminal may be, for example, a mobile phone, a wearable device, an Internet of Things device that supports WiFi communication, a car with WiFi communication, a smart car, a tablet computer, a computer with wireless transceiver function, a virtual reality (VR) terminal device, an augmented reality (AR) terminal device, a wireless terminal device in industrial control, a wireless terminal device in self-driving, a wireless terminal device in remote medical surgery, a wireless terminal device in a smart grid, a wireless terminal device in transportation safety, a wireless terminal device in a smart city, or a wireless terminal device in a smart home, but is not limited thereto.

[0102] Specifically, source device 101, relay device 102, or target device 103 may be a terminal device or network device equipped with a Wireless Fidelity (WiFi) chip. Optionally, source device 101 or relay device 102 may support multiple WLAN standards, such as 802.11ax, 802.11be, 802.11ac, 802.11n, 802.11g, 802.11b, 802.11a, 802.11bf, and 802.11bn, as well as support for the next generation 802.11 protocol, but is not limited thereto.

[0103] Optionally, in an embodiment of the present disclosure, the AP and STA may be devices supporting multiple connections, for example, they may be represented as a multi-connection access point device (AP MLD) and a multi-connection site device (Non-Access Point Multi-Link Device, Non-AP MLD), respectively; the AP MLD may represent an access point supporting multi-connection communication functions, and the non-AP MLD may represent a site supporting multi-connection communication functions.

[0104] It can be understood that the communication system described in the embodiment of the present disclosure is for the purpose of more clearly illustrating the technical solution of the embodiment of the present disclosure, and does not constitute a limitation on the technical solution proposed in the embodiment of the present disclosure. Ordinary technicians in this field can know that with the evolution of the system architecture and the emergence of new business scenarios, the technical solution proposed in the embodiment of the present disclosure is also applicable to similar technical problems.

[0105] The following embodiments of the present disclosure may be applied to the communication system 100 shown in FIG1 , or a portion thereof, but are not limited thereto. The entities shown in FIG1 are illustrative only. The communication system may include all or part of the entities shown in FIG1 , or may include other entities outside of FIG1 . The number and form of the entities are arbitrary, and the entities may be physical or virtual. The connection relationships between the entities are illustrative only. The entities may be connected or disconnected, and the connection may be in any manner, including direct or indirect, wired or wireless.

[0106] The various embodiments of the present disclosure can be applied to wireless local area networks (WLANs), such as those using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component of a WLAN. A BSS network consists of station devices with some association 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 dedicated to managing the BSS, called an access point, and all other STAs in the network are associated with it. Other stations in the BSS network that are not the central station are called terminals, also called non-AP STAs. Terminals 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, and other factors, a STA cannot detect other STAs that are farther away from it, and the two STAs are each other's hidden nodes.

[0107] FIG2 is an interactive diagram of a data relay transmission method according to an embodiment of the present disclosure. As shown in FIG2 , the method includes:

[0108] In step 201, the source device 101 determines a first data frame; wherein the first data frame includes first identification information, and the first identification information identifies that the source device 101 enters sleep mode after receiving a first BA frame sent by the relay device 102; wherein the first BA frame is sent by the relay device 102 in response to a second BA frame; and the second BA frame is used to confirm that the target device receives the first data frame forwarded by the relay device 102.

[0109] In UHR, in order to achieve high-quality data transmission (levels Rate-vs-Range) under different Signal to Interference and Noise Ratio (SINR), a relay transmission method may be used to transmit data frames. As an example, referring to FIG3 , during data relay transmission, the source device (Source, or sending device) transmits a relay data frame, such as PPDU-1, to the relay device (Relay) via a relay link. After the relay device performs necessary address padding on the relay data frame, it forwards the relay data frame (such as PPDU-2) to the destination device (Destination, or receiving device). In addition, the source device can also transmit data frames to the destination device via a direct link. In the embodiment of the present disclosure, the relay end can also be an AP. For ease of explanation, STA will be used as the relay end in the following description, but this does not constitute a limitation to the embodiment of the present disclosure.

[0110] Furthermore, relay transmission can be categorized into uplink and downlink transmission. For example, in an uplink transmission scenario, the source and relay devices are STAs, and the destination device is an AP. Within a transmission opportunity (TXOP), the STA sends data frames to the relay STA, which then forwards them to the destination AP. In a downlink transmission scenario, the source device is the AP, and the relay and destination devices are STAs. Within a TXOP, the AP sends data frames to the relay STA, which then forwards them to the destination STA.

[0111] During the relay transmission process, a block acknowledgment (BA) mechanism is required to ensure successful data frame transmission. Taking downlink relay transmission as an example, there may be three BA frame transmissions. The first is the acknowledgment sent by relay device 102 (Relay STA) to source device 101 (AP), used to confirm the receipt of the data frame sent by the AP to the relay STA; the second is the acknowledgment sent by target device 103 (target STA) to the relay STA, used to confirm the receipt of the data frame forwarded by the relay STA to the target STA; the third is the BA forwarded by the relay STA to the AP after the second BA is sent, used to notify the AP that the target STA has received the data frame transmitted via the relay, that is, the data frame has arrived at its receiving end. Similarly, in uplink relay transmission, there may also be three BA acknowledgments: the first is the acknowledgment sent by the relay STA to the source STA, the second is the acknowledgment sent by the destination AP to the relay STA, and the third is the BA forwarded by the relay STA to the source STA after the second BA is sent.

[0112] When three BA confirmations are present, the source device sets the power management (PM) bit in the frame control (FC) field of the media access control (MAC) layer header to 1 in the data frame it transmits, indicating that it has entered power saving (PS) or power saving mode. After forwarding the source STA's data frame, the relay STA can also set the PS bit in the FC field of the relay STA's MAC header to 1, indicating that the relay STA will also enter PS mode. However, due to the three BA confirmations, if the source device enters PS mode after sending a data frame and receiving the first BA confirmation from the relay device, it will not receive the third BA confirmation. Furthermore, the relay device may not buffer the forwarded data frame. If the source device enters PS mode after sending a data frame to the relay device, it will not receive the third BA forwarded by the relay device, and thus will not be able to understand the destination device's final reception of the data frame.

[0113] Therefore, in the embodiment of the present disclosure, during the relay transmission process, the source device 101 determines the first data frame, carries the first identification information in the first data frame, and identifies through the first identification information that: the source device 101 enters the sleep mode after receiving the first BA frame (equivalent to the aforementioned third BA) sent by the relay device 102; wherein, the first BA frame is sent by the relay device 102 in response to the second BA frame; the second BA frame is used to confirm that the target device has received the first data frame forwarded by the relay device 102. In other words, after receiving the first data frame forwarded by the relay device 102, the target device sends the second BA frame (equivalent to the aforementioned second BA) to the relay device 102; after receiving the second BA frame, the relay device 102 sends the first BA frame (equivalent to the aforementioned third BA) to the source device 101; in this way, after receiving the first BA frame, the source device 101 can confirm that the target device has successfully received the first data frame forwarded by the relay device 102.

[0114] In this way, the source device 101 can understand the reception status of the final data frame by the target device, improve the reliability of data relay transmission and system throughput, and meet UHR requirements. It is understandable that the source device 101 can be an AP, or a STA in consideration of AP power saving.

[0115] In some embodiments, the first identification information includes a first identification bit and a second identification bit; the first identification bit identifies whether the source device 101 enters a power saving state after the first data frame is sent, and the second identification bit identifies whether the first data frame is the last frame.

[0116] For example, the first identification information includes a first identification bit, which can be: the PM bit in the FC control field of the MAC frame header of the first data frame. For example, the PM bit is set to "0", indicating that the source device 101 does not enter the power saving state after the first data frame is sent. On the contrary, the PM bit is set to "1", indicating that the source device 101 enters the power saving state after the first data frame is sent.

[0117] The second identification bit can be the more data bit in the FC control field of the MAC frame header of the first data frame. For example, the more data bit is set to "0", indicating that the first data frame is not the last frame, that is, there are other data frames to be sent during the relay transmission; conversely, the more data bit is set to "1", indicating that the first data frame is the last frame, that is, there are no other data frames to be sent during the relay transmission.

[0118] In some embodiments, the first identification bit indicates that the source device 101 enters a power saving state after the first data frame is sent, and the second identification bit indicates that the first data frame is the last frame, then the first identification information indicates that the source device 101 enters a sleep state after receiving the first BA frame and the second BA frame fed back by the relay device 102.

[0119] For example, the first identification bit indicates that the source device 101 enters the power saving state after the first data frame is sent, and the second identification bit indicates that the first data frame is the last frame, that is, the first identification information identifies the current data frame as the last frame. Then, after the source device 101 receives the first BA frame and the second BA frame fed back by the relay device 102, it confirms that the target device has successfully received the first data frame forwarded by the relay device 102 and can enter the sleep state.

[0120] Step 202: The source device 101 sends the first data frame to the relay device 102.

[0121] Relay device 102 is a relay STA that maintains a communication connection with source device 101. Source device 101 sends a first data frame to relay device 102, requesting relay device 102 to forward the first data frame to the target device to transmit uplink data or downlink data, thereby increasing the data transmission rate and reducing the transmission delay.

[0122] For example, in uplink communication, source device 101 (sending STA) sends a first data frame to relay device 102 (Relay STA), which then sends the frame to the destination device (destination AP) via relay device 102. For another example, in downlink communication, source device 101 (AP) sends a first data frame to relay device 102 (Relay STA), which then sends the frame to the destination device (destination STA) via relay device 102.

[0123] Step 203: the relay device 102 receives the first data frame;

[0124] The relay device 102 receives the first data frame sent by the source device 101, obtains the first identification information in the first data frame, and then learns from the first identification information that the source device enters the sleep mode after receiving the first BA frame sent by the relay device.

[0125] In some embodiments, after sending the first data frame, the method further includes:

[0126] Receive a third BA frame sent by the relay device 102; the third BA frame is used to confirm that the relay device 102 has received the first data frame sent by the source device 101.

[0127] After receiving the first data frame sent by the source device 101 , the relay device 102 feeds back a third BA frame to the source device 101 . The third BA frame is used to confirm that the relay device has received the first data frame sent by the source device.

[0128] Step 204 : The relay device 102 forwards the first data frame to the target device 103 .

[0129] In step 205 , after receiving the first data frame, the target device 103 feeds back a second BA frame to the relay device 102 . The second BA frame is used to confirm that the target device has received the first data frame forwarded by the relay device.

[0130] Step 206 : After receiving the second BA frame, the relay device 102 sends the first BA frame to the source device 101 .

[0131] The first BA frame is sent by the relay device in response to the second BA frame. The second BA frame is used to confirm that the destination device has received the first data frame forwarded by the relay device. For example, after relay device 102 sends the first data frame to the destination device, the destination device feeds back the second BA frame to relay device 102. After confirming the transmission of the second BA frame, relay device 102 sends the first BA frame to source device 101.

[0132] Step 207 : After receiving the first BA frame sent by the relay device 102 , the source device 101 enters a sleep mode.

[0133] In an embodiment of the present disclosure, during the Relay transmission process, the source device 101 determines a first data frame and carries first identification information in the first data frame. The first identification information identifies that: the source device 101 enters sleep mode after receiving the first BA frame sent by the relay device 102 (equivalent to the aforementioned third BA); wherein the first BA frame is sent by the relay device 102 in response to the second BA frame; the second BA frame is used to confirm that the target device has received the first data frame forwarded by the relay device 102.

[0134] In this way, source device 101 can understand the destination device's reception status of the final data frame, improving the reliability of data relay transmission and system throughput, and meeting UHR requirements. It is understood that source device 101 can be an AP, or, considering AP power saving, a STA. The disclosed embodiments improve the mechanism for the source device to enter sleep mode during data relay transmission, improving the reliability of data relay transmission and system throughput, making it suitable for UHR requirements and improving spectrum utilization.

[0135] As an example, referring to FIG4 , FIG4 shows an optional implementation of the embodiment of the present disclosure, including the following steps:

[0136] In step 401 , the source device 101 sends the last frame and enters a sleep mode.

[0137] Step 402 : After receiving the data frame, the relay device 102 sends a first BA frame to the source device 101 .

[0138] In step 403, the relay device 102 forwards the data frame to the target device 103. At this time, neither the source device 101 nor the relay device 102 enters the sleep mode.

[0139] Step 404 : The target device 103 receives the data frame forwarded by the relay device 102 and sends a second BA frame to the relay device 102 .

[0140] In step 405 , the relay device 102 receives the second BA frame and sends a third BA frame (ie, the first BA frame) to the source device 101 . At this time, the source device 101 and the relay device 102 may enter a sleep mode.

[0141] In some embodiments, the method further comprises:

[0142] If the first data frame is retransmitted, it is relayed again within the TXOP shared by the access point device.

[0143] When the first data frame is retransmitted, the access point device may obtain a relay transmission opportunity and share it with the source device, so that the source device can perform relay transmission again within the TXOP, thereby ensuring the transmission of low-latency service data.
