The AP is equivalent to a bridge connecting the wired network and the 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 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.

[0159] 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.

[0160] 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.

[0161] 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.

[0162] 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.

[0163] 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:

[0164] In step 201, the access point device 101 determines, within a transmission opportunity TXOP, that multiple users request to send a transmission opportunity sharing triggering MU-RTS TXS frame; wherein the MU-RTS TXS frame includes first duration information and second duration information; the first duration information includes the duration for the source device to send a data frame to the relay device; and the second duration information includes the duration for the relay device to forward the data frame to the target device.

[0165] In UHR, in order to achieve high-quality data transmission (levels Rate-vs-Range) at different Signal to Interference and Noise Ratio (SINR), a relay transmission method may be used to transmit data frames. As an example, referring to FIG4 , 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, the 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.

[0166] 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.

[0167] During the relay transmission process, after obtaining a TXOP, the access point device allocates the obtained TXOP to the associated STA devices via a Multi-User Request to Send (MU RTS) transmission opportunity sharing (TXS) trigger frame. The TXOP is used by the associated STA devices for non-trigger-based (Non-TB) data transmission or peer-to-peer (P2P) data transmission. In the disclosed embodiment, the access point device 101 determines a MU-RTS TXS frame within a TXOP and carries the first duration information and the second duration information in the MU-RTS TXS frame.

[0168] Among them, the first duration information includes the duration of the source device sending the data frame to the relay device, such as the sending duration of PPDU-1 in Figure 4. During the transmission process of downlink data, the access point device acts as the source device to send the downlink data frame to the relay device, and the first duration information includes the duration information of the access point device sending the data to the relay device; during the transmission process of uplink data, the site device acts as the source device to send the downlink data frame to the relay device, and the second duration information is the duration information of the site device sending the data to the relay device.

[0169] The second duration information includes the duration for the relay device to forward the data frame to the target device, such as the sending duration of PPDU-2 in Figure 4. During the transmission process of downlink data, the relay device sends a downlink data frame to the site device, and the first duration information includes the duration information for the relay device to send data to the site device; during the transmission process of uplink data, the access point device serves as the target device, and the second duration information is the duration information for the relay device to send data to the access point device.

[0170] In this way, within the TXOP obtained by the access point device, the access point device shares the TXOP with the site device through the MU-RTS TXS frame, and carries the first duration information and the second duration information in the MU-RTS TXS frame. Subsequently, during the data relay process, the site device and the access point device respectively relay data transmission according to the time indicated by the first duration information and the second duration information, and can perform uplink data transmission and downlink data transmission. In the related art, the MU-RTS TXS frame usually only contains one STA info field. Therefore, the associated STA in the STA info can only send uplink non-TB PPDU alone, or send uplink non-TB PPDU and P2P communication alone, and cannot transmit downlink relay data. In the embodiment of the present disclosure, the first duration information and the second duration information are used to indicate the two time lengths for relay data transmission, respectively, and uplink data transmission and downlink data transmission can be performed.

[0171] Step 202: In a downlink transmission scenario, the MU-RTS TXS frame is sent.

[0172] In the downlink transmission scenario, the access point device sends a MU-RTS TXS frame to the relay device to share the TXOP obtained by the access point device with the station device.

[0173] As shown in step 302 in FIG. 3 , in an uplink transmission scenario, the access point device sends a MU-RTS TXS frame to the station device.

[0174] In some embodiments, the first duration information further includes the duration of the confirmation message frame replied by the relay device to the source device and the short frame interval;

[0175] The second duration information also includes: the duration for the target device to reply a confirmation message frame to the relay device, the duration for the relay device to reply a confirmation message frame to the source device, and a short frame interval.

[0176] The first duration information includes the duration information of the access point device sending data to the relay device, and also includes the duration of the relay device replying an acknowledgment message frame to the source device and a short inter frame space (SIFS). That is, after the access point device sends a data frame to the relay device, it needs to wait for a short inter frame space and wait for the acknowledgment message (ACK) frame replied by the relay device to ensure that sufficient time is allocated to the relay device to receive the data frame.

[0177] The second duration information includes the duration of the relay device forwarding the data frame to the target device, and also includes: the duration of the target device replying a confirmation message frame to the relay device, the duration of the relay device replying a confirmation message frame to the source device, and a short frame interval. In other words, the second duration information also includes: (1) the time it takes for the target device to reply a confirmation message frame to the relay device after receiving the data frame forwarded by the relay device; (2) the time it takes for the relay device to reply a confirmation message frame to the source device after receiving the confirmation message frame sent by the aforementioned target device, and a short frame interval, which is the short frame interval between two confirmation message frames.

[0178] It can be understood that the source device and the target device are specifically access point devices or station devices, and are confirmed based on the uplink and downlink directions of the transmitted data, which will not be further described in the embodiment of the present disclosure.

[0179] In some embodiments, the MU-RTS TXS frame further includes: identification information of a site device corresponding to the first duration information and the second duration information, the identification information being, for example, an Association Identifier (AID);

[0180] The first duration information, the second duration information, and the identification information are carried in a user information User info field or a common information Common info field of the MU-RTS TXS frame.

[0181] As an example, the fields in the MU-RTS TXS frame that share the TXOP for a certain station device are shown in Table 1 below:

[0182] Table 1:

[0183] The AID field is used to carry the AID of the site device;

[0184] The Time allocation1 field is used to carry the first duration information;

[0185] The Time allocation2 field is used to carry the second duration information.

[0186] In some embodiments, the User Info field of the MU-RTS TXS frame includes at least one of the following:

[0187] Direction identification information, indicating whether the relay transmission triggered by the MU-RTS TXS frame is uplink transmission or downlink transmission; for example, if the direction identification information is set to "0", it indicates a downlink relay, that is, it is sent by the AP to the relay STA, and then forwarded by the relay STA to the target STA; if the direction identification information is set to "1", it indicates an uplink relay, that is, it is sent by the source STA to the relay STA, and then forwarded by the relay STA to the target AP.

[0188] Resource unit allocation (RU allocation) information, used to carry the transmission resources allocated by the access point device to the station device. Optionally, the RU allocation is 8 bits. Considering the complexity of data relay, its transmission mode is channel exclusive, and it can use 20MHz, 40MHz, 80MHz, or 160MHz for transmission, where different bits are used to identify the RU corresponding to each channel bandwidth.

[0189] The spatial stream (SS) information identifies the number of spatial streams (SSs) of the data frames sent by the relay device to the target device, and may be the same as the number of spatial streams (SSs) sent by the source device to the relay device.

[0190] In some embodiments, the Common Info field of the MU-RTS TXS frame includes at least one of the following:

[0191] Spatial stream SS information, which identifies the number of SSs of data frames sent by the source device to the relay device;

[0192] Uplink / downlink UL / DL modulation and coding strategy MCS information (UL / DL MCS information), which identifies the modulation and coding scheme (MCS) of the uplink or downlink transmission triggered by the MU-RTS TXS frame. The MCS method includes the number of spatial streams, modulation method, transmit power, etc.

[0193] UL / DL bandwidth (BW) information, identifying bandwidth (Bandwidth, BW) information of uplink transmission or downlink transmission triggered by the MU-RTS TXS frame;

[0194] More triggers the more TF field, indicating whether multiple relay transmissions will occur in one TXOP;

[0195] Identification information of the target device, such as AID; if the target device is an access point device, a special AID, such as "0", may be configured for the target device;

[0196] The identification information of the relay device is, for example, an AID. If the relay device is an access point device, a special AID, for example, "0", may be configured for the relay device.

[0197] In some embodiments, the receiving address RA of the MU-RTS TXS frame is a broadcast address or a multicast address, which is used for reception by multiple devices. For example, as shown in the downlink transmission scenario in Figure 2, step 202 can be sent to the relay device; it can also be sent to the site device, for example, as shown in the uplink transmission scenario in Figure 3, step 302.

[0198] In some embodiments, after step 202, a data relay process may be performed. Steps 203 to 209 in FIG. 2 illustrate a downlink transmission process, and steps 303 to 309 in FIG. 3 illustrate an uplink transmission process.

[0199] Specifically, the downlink transmission process is shown in FIG2 . After step 202 , the method includes:

[0200] Step 203: The relay device sends a Clear to Send (CTS) frame to the access point device, triggering the access point device to send a downlink data frame.

[0201] Step 204: The relay device receives the downlink data frame within the time indicated by the first duration information.

[0202] Step 205: within the time indicated by the second duration information, the relay device forwards the downlink data frame to the site device.

[0203] In addition, within the time indicated by the first duration information, the access point device further executes step 206. In step 206, within the time period indicated by the first duration information, the access point device updates the network allocation vector (NAV) of the access point device to an idle state and sends downlink data frames to the relay device using the access channel.

[0204] When the time indicated by the second duration information arrives, the access point device further performs step 207, and enters a power saving state or updates the NAV of the access point device to a busy state to save power.

[0205] During the time indicated by the first duration information, the site device executes step 208 , and during the time period indicated by the first duration information, the site device enters a power saving state or updates the NAV of the site device to a busy state to save power.

[0206] Step 209: When the time indicated by the second duration information arrives, the NAV of the site device is updated to an idle state, so as to access a channel to receive downlink data frames forwarded by the relay device.

[0207] In some embodiments, after step 302, steps 303 to 309 in Figure 3 illustrate the uplink transmission process. Steps 301 and 302 refer to steps 201 and 202, and are not described in detail here.

[0208] Specifically, the uplink transmission process is shown in FIG3 . After step 303 , the method includes:

[0209] Step 303: The station device sends a Clear to Send (CTS) frame to the access point device, triggering the access point device to receive an uplink data frame.

[0210] Step 304: within the time indicated by the first duration information, the site device sends an uplink data frame to the relay device.

[0211] Step 305: within the time indicated by the second duration information, the relay device forwards the uplink data frame to the access point device.

[0212] In addition, within the time indicated by the first duration information, the access point device further executes step 306. In step 306, within the time period indicated by the first duration information, the access point device enters a power saving state or updates the NAV of the access point device to a busy state to save power.

[0213] When the time indicated by the second duration information arrives, the access point device further executes step 307 to update the NAV of the site device to an idle state to access the channel to receive the uplink data frame forwarded by the relay device.

[0214] Within the time indicated by the first duration information, the site device executes step 308. Within the time period indicated by the first duration information, the access point device updates the network allocation vector (NAV) of the site device to an idle state and sends uplink data frames to the relay device via the access channel.

[0215] Step 309: When the time indicated by the second duration information arrives, the site device enters a power saving state, or updates the NAV of the site device to a busy state to save power.

[0216] In the disclosed embodiment, within the TXOP obtained by the access point device, the access point device shares the TXOP with the station device via a MU-RTS TXS frame, and carries first duration information and second duration information in the MU-RTS TXS frame. Subsequently, during data relay, the station device and the access point device relay data transmission according to the times indicated by the first duration information and the second duration information, respectively, and can perform both uplink and downlink data transmission. The disclosed embodiment provides an implementation method for a TXOP sharing mechanism in a data relay scenario to meet the transmission requirements of UHR.
