[0144] 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.

[0145] 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.

[0146] 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.

[0147] 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.

[0148] 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 Figure 4, during data relay transmission, the source device (Source, or sending device) transmits a relay data frame (e.g., 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 (e.g., 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 device can also be an AP. For ease of explanation, the STA will be used as the relay device in the following description, but this does not constitute a limitation on the embodiment of the present disclosure.

[0149] 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. During a transmission opportunity (TXOP), the STA sends data frames to the relay STA, which then forwards them to the destination AP. This is downlink data relay transmission via the relay STA. In a downlink transmission scenario, the source device is the AP, and the relay and destination devices are STAs. During a TXOP, the AP sends data frames to the relay STA, which then forwards them to the destination STA. This is uplink data relay transmission via the relay device.

[0150] FIG2 is one of the interactive schematic diagrams of the data relay transmission method according to an embodiment of the present disclosure. As shown in FIG2 , in a downlink transmission scenario, the method includes:

[0151] In step 201 , the access point device 101 sends forbidden sub-channel bitmap information to the relay device 102 and the station device 103 respectively.

[0152] Optionally, in some embodiments, the access point device 101 may send prohibited sub-channel bitmap information to the relay device 102 through steps 202 and 203 , or steps 204 and 205 .

[0153] In step 202, the access point device 101 determines a first radio frame during the process of establishing an initial association with the relay device 102; the first radio frame includes an EHT (Extremely High Throughput) operation information element, and the disabled subchannel bitmap information is carried in the EHT operation information element.

[0154] Optionally, the first radio frame may include but is not limited to a beacon frame, a probe response frame, an association response frame, and a reassociation response frame.

[0155] Optionally, the fields of the EHT operation information element of the first radio frame may be as shown in Table 1 below:

[0156] Table 1:

[0157] As shown in Table 1, the EHT operation information elements include but are not limited to the Control field, CCFS0 field, CCFS1 field, and Disable Subchannel Bitmap field. The Control field has a byte length of 1, the CCFS0 field has a byte length of 1, the CCFS1 field has a byte length of 1, and the Disable Subchannel Bitmap field has a byte length of 0 or 2.

[0158] As an example, the Disable Subchannel Bitmap field can be used as sub-bitmap information for disabling subchannels. When the Disable Subchannel Bitmap field contains a bit with a parameter value of 1, it is determined that a punctured channel exists in the channel bandwidth of the BSS, and the number of bytes in the Disable Subchannel Bitmap field is 2, which indicates that the operating bandwidth of the first data frame uses the punctured channel mode. When the Disable Subchannel Bitmap field does not contain a bit with a parameter value of 1, it is determined that no punctured channel exists in the channel bandwidth of the BSS, and the number of bytes in the Disable Subchannel Bitmap field is 0, which indicates that the operating bandwidth of the first data frame does not use the punctured channel mode.

[0159] Step 203 : The access point device 101 sends the first wireless frame to the relay device 102 .

[0160] In step 204 , the access point device 101 determines a second radio frame during TXOP sharing with the site device 103 ; the second radio frame includes a MU-RTS TXS frame, and the disabled subchannel bitmap information is carried in the MU-RTS TXS frame.

[0161] During the relay transmission process, after obtaining a TXOP, the access point device 101 allocates the obtained TXOP to associated STA devices via a Multi-User Request to Send (MU RTS) transmission opportunity sharing (TXS) trigger frame. The TXOP is then 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 uses the MU-RTS TXS frame to carry the disabled subchannel bitmap information.

[0162] Optionally, the disabled subchannel bitmap information can be carried in the RU allocation field (resource unit allocation) in the user information field of the MU-RTS TXS frame. The RU allocation field is used to carry the transmission resources allocated by the access point device 101 to the station device 103 or the relay device 102.

[0163] In step 205 , the access point device 101 sends the second radio frame to the relay device 102 , instructing the relay device 102 to forward the second radio frame to the station device 103 .

[0164] Optionally, after receiving the second radio frame, the relay device 102 may also forward the second radio frame to the site device 103 , instructing the site device 103 to determine whether the operating bandwidth of the first data frame uses a punctured channel mode.

[0165] Optionally, in some embodiments, the access point device 101 may send prohibited sub-channel bitmap information to the station device 103 through steps 206 and 207 .

[0166] Step 206 : The access point device 101 determines a third radio frame during the process of establishing an initial association with the site device 103 ; the third radio frame includes an EHT operation information element, and the forbidden subchannel bitmap information is carried in the EHT operation information element.

[0167] The specific format of the EHT operation information element can be found in step 202 and will not be described in detail here.

[0168] Step 207 : The access point device 101 sends the third radio frame to the station device 103 .

[0169] In the above embodiment, the access point device 101 can instruct the relay device 102 to determine whether the operating bandwidth of the data frame transmitted by the access point device 101 to it uses the perforated channel mode by sending the first radio frame to the relay device 102 during the process of associating with the relay device 102, or sending the second radio frame to the relay device 102 during the process of TXOP sharing between the access point device 101 and the station device 103.

[0170] The access point device 101 may send a third radio frame to the station device 103 during the association process with the station device 103 to instruct the station device 103 to determine whether the operating bandwidth of the data frames transmitted by the access point device 101 to the station device 103 uses the punctured channel mode.

[0171] During the TXOP sharing process between the access point device 101 and the site device 103, after receiving the second wireless frame, the relay device 102 forwards the second wireless frame to the site device 103, and can instruct the site device 103 to determine whether the operating bandwidth of the data frame transmitted to it by the access point device 101 through the relay device 102 uses the perforated channel mode.

[0172] In step 208 , the access point device 101 determines a downlink data frame (ie, a first data frame).

[0173] In step 209 , the access point device 101 sends a downlink data frame to the relay device 102 , instructing the relay device 102 to determine that the operating bandwidth of the downlink data frame uses a punctured channel mode, and forward the downlink data frame to the station device 103 using the punctured channel mode.

[0174] Optionally, in some embodiments, the puncturing channel mode is identified by disabling sub-channel bitmap information;

[0175] The flag bit in the disabled sub-channel bitmap information is set to a first parameter value, indicating that the sub-channel corresponding to the flag bit is a disabled sub-channel (punctured channel) for transmitting downlink data frames;

[0176] The identification bit in the disabled sub-channel bitmap information is set to a second parameter value, identifying the sub-channel corresponding to the identification bit as a non-disabled sub-channel for transmitting downlink data frames.

[0177] During relay transmission, a punctured channel pattern is used to maximize bandwidth. This pattern improves channel utilization by punching holes in and shielding the punctured channels within a group of channels and bundling the non-punctured channels together for transmission.

[0178] Optionally, the disable subchannel bitmap field can be used to identify the disabled subchannel sub-bitmap information, with each bit in the disable subchannel bitmap field representing an identification bit. When the bit is set to 1 (i.e., the first parameter value), the subchannel corresponding to the bit is identified as a punctured channel for transmitting downlink data frames. When the bit is set to 0 (i.e., the second parameter value), the subchannel corresponding to the bit is identified as a non-disabled subchannel for transmitting downlink data frames.

[0179] Optionally, if a higher channel bandwidth is supported in the UHR, such as 640 MHz, a 20 MHz channel bandwidth may be used as the basic bandwidth, a 40 MHz channel bandwidth may be used as the basic bandwidth, or an 8040 MHz channel bandwidth may be used as the basic bandwidth.

[0180] As an example, if the basic bandwidth is 20 MHz channel bandwidth and the total bandwidth is 160 MHz (i.e., there are 8 transmission channels), and two of the MHz channels need to be used as punctured channels, the format of the disable subchannel bitmap field can be set to 11000000. In the disable subchannel bitmap field, the channels indicated by the bits set to "1" are punctured channels.

[0181] In the disclosed embodiment, the access point device 101 determines a downlink data frame; sends the downlink data frame to the relay device 102, instructs the relay device 102 to determine the operating bandwidth of the downlink data frame using the puncturing channel mode, and forwards the downlink data frame to the site device 103 using the puncturing channel mode. In this way, when the access point device 101 uses the puncturing channel mode to communicate with the relay device 102, it also instructs the relay device 102 to use the puncturing channel mode to communicate with the site device 103. This can improve the mechanism of using the puncturing channel mode for transmission during relay transmission, communicate as much as possible under the maximum BSS bandwidth, improve transmission reliability, and increase system throughput to meet UHR requirements.

[0182] In step 210 , the relay device 102 determines that the operating bandwidth of the downlink data frame uses a punctured channel mode, and forwards the downlink data frame to the site device using the punctured channel mode.

[0183] In the embodiment of the present disclosure, when the relay device 102 determines that the access point device 101 adopts the perforated channel mode to communicate with the relay device 102, the perforated channel mode is also adopted to communicate with the site device 103. This can improve the mechanism of adopting the perforated channel mode for transmission during the relay transmission process, communicate as much as possible under the large bandwidth of the BSS, improve the reliability of transmission, and improve the system throughput, so as to make it suitable for UHR requirements.

[0184] Optionally, in some embodiments, the forwarding of the downlink data frame to the site device 103 using the punctured channel pattern includes:

[0185] In the sub-channel whose identification bit in the disabled sub-channel bitmap information is set to the second parameter value, the downlink data frame is forwarded to the site device 103.

[0186] In the above embodiment, when the relay device 102 determines that the access point device 101 adopts the puncturing channel mode to communicate with the relay device 102, the bandwidth indicated by the non-forbidden channel in the BSS bandwidth indicated by the puncturing channel mode is also adopted to forward the downlink data frame sent by the access point device 101 to the site device 103. This can improve the mechanism of adopting the puncturing channel mode for transmission during the relay transmission process, communicate as much as possible under the large BSS bandwidth, improve the transmission reliability, improve the system throughput, and make it suitable for UHR requirements.

[0187] Optionally, in some embodiments, the forwarding of the downlink data frame to the site device 103 using the punctured channel pattern includes:

[0188] The access point device 101 receives a change in the disabled sub-channel bitmap information sent by the access point device 101 , and forwards the downlink data frame to the station device 103 using the puncturing channel pattern corresponding to the changed disabled sub-channel bitmap information.

[0189] Optionally, when the forbidden sub-channel bitmap information changes, the access point device 101 may broadcast the changed forbidden sub-channel bitmap information through a beacon frame, a probe response, an association response, or a reassociation response.

[0190] Optionally, the above-mentioned method of determining the puncturing channel pattern corresponding to the disabled sub-channel bitmap information may be used to determine the puncturing channel pattern corresponding to the changed disabled sub-channel bitmap information.

[0191] In the above embodiment, when the disabled sub-channel bitmap information received by the relay device 102 from the access point device 101 changes, the relay device 102 uses the puncturing channel mode corresponding to the changed disabled sub-channel bitmap information to forward the downlink data frame to the site device 103, thereby improving the real-time performance of the transmission process and reducing the transmission delay.

[0209] Step 307 : The access point device 101 sends the third radio frame to the station device 103 .

[0210] The optional implementation of step 307 can refer to the optional implementation of step 207 in Figure 2 and other related parts in the embodiment involved in Figure 2, which will not be repeated here.

[0211] In the above embodiment, the access point device 101 can instruct the relay device 102 to determine whether the operating bandwidth of the data frame transmitted by the access point device 101 to it uses the perforated channel mode by sending the first radio frame to the relay device 102 during the process of associating with the relay device 102, or sending the second radio frame to the relay device 102 during the process of TXOP sharing between the access point device 101 and the station device 103.

[0212] The access point device 101 may send a third radio frame to the station device 103 during the association process with the station device 103 to instruct the station device 103 to determine whether the operating bandwidth of the data frames transmitted by the access point device 101 to the station device 103 uses the punctured channel mode.

[0213] During the TXOP sharing process between the access point device 101 and the site device 103, after receiving the second wireless frame, the relay device 102 forwards the second wireless frame to the site device 103, and can instruct the site device 103 to determine whether the operating bandwidth of the data frame transmitted to it by the access point device 101 through the relay device 102 uses the perforated channel mode.

[0214] In step 308 , the site device 103 determines an uplink data frame (ie, a second data frame).

[0215] In step 309 , the station device 103 sends an uplink data frame to the relay device 102 , instructing the relay device 102 to determine an operating bandwidth of the uplink data frame using a punctured channel mode, and to forward the uplink data frame to the access point device 101 using the punctured channel mode.

[0216] Optionally, in some embodiments, the puncturing channel mode is identified by disabling sub-channel bitmap information;

[0217] The flag bit in the disabled sub-channel bitmap information is set to a first parameter value, indicating that the sub-channel corresponding to the flag bit is a disabled sub-channel (punctured channel) for transmitting uplink data frames;

[0218] The identification bit in the disabled sub-channel bitmap information is set to a second parameter value, indicating that the sub-channel corresponding to the identification bit is a non-disabled sub-channel for transmitting uplink data frames.

[0219] During relay transmission, a punctured channel pattern is used to maximize bandwidth. This pattern improves channel utilization by punching holes in and shielding the punctured channels within a group of channels and bundling the non-punctured channels together for transmission.

[0220] Optionally, the disable subchannel bitmap field can be used to identify the disable subchannel subbitmap information, with each bit in the disable subchannel bitmap field representing an identification bit.

When the bit is set to 0 (i.e., the second parameter value), the subchannel corresponding to the bit is identified as a non-disabled subchannel for transmitting uplink data frames.

[0221] As an example, if the basic bandwidth is 20 MHz channel bandwidth and the total bandwidth is 160 MHz (i.e., there are 8 transmission channels), and two of the MHz channels need to be used as punctured channels, the format of the disable subchannel bitmap field can be set to 11000000. In the disable subchannel bitmap field, the channels indicated by the bits set to "1" are punctured channels.

In this way, when the site device 103 adopts the puncturing channel mode to communicate with the relay device 102, it also instructs the relay device 102 to adopt the puncturing channel mode to communicate with the access point device 101. This can improve the mechanism of using the puncturing channel mode for transmission during relay transmission, communicate as much as possible under the large BSS bandwidth, improve transmission reliability, and improve system throughput, making it suitable for UHR requirements.

[0223] In step 310 , the relay device 102 determines that the operating bandwidth of the uplink data frame uses a punctured channel mode, and forwards the uplink data frame to the access point device 101 using the punctured channel mode.

[0224] In the embodiment of the present disclosure, when the relay device 102 determines that the site device 103 adopts the perforated channel mode to communicate with the relay device 102, the perforated channel mode is also adopted to communicate with the access point device 101. This can improve the mechanism of adopting the perforated channel mode for transmission during the relay transmission process, communicate as much as possible under the large bandwidth of the BSS, improve the reliability of transmission, and improve the system throughput, so as to make it suitable for UHR requirements.

[0225] Optionally, in some embodiments, the forwarding of uplink data frames to the access point device 101 using the puncturing channel mode includes:

[0226] In the sub-channel whose identification bit in the forbidden sub-channel bitmap information is set to the second parameter value, the uplink data frame is forwarded to the access point device 101.

[0227] In the above embodiment, when the relay device 102 determines that the site device 103 adopts the puncturing channel mode to communicate with the relay device 102, the bandwidth indicated by the non-forbidden channel in the BSS bandwidth indicated by the puncturing channel mode is also adopted to forward the uplink data frame sent by the site device 103 to the access point device 101. This can improve the mechanism of adopting the puncturing channel mode for transmission during the relay transmission process, communicate as much as possible under the large BSS bandwidth, improve the transmission reliability, improve the system throughput, and make it suitable for UHR requirements.

[0228] Optionally, in some embodiments, the forwarding of uplink data frames to the access point device 101 using the puncturing channel mode includes:

[0229] The access point device 101 receives a change in the disabled sub-channel bitmap information sent by the access point device 101 , and forwards uplink data frames to the access point device 101 using the puncturing channel pattern corresponding to the changed disabled sub-channel bitmap information.

[0230] Optionally, when the forbidden sub-channel bitmap information changes, the access point device 101 may broadcast the changed forbidden sub-channel bitmap information through a beacon frame, a probe response, an association response, or a reassociation response.

[0231] Optionally, the above-mentioned method of determining the puncturing channel pattern corresponding to the disabled sub-channel bitmap information may be used to determine the puncturing channel pattern corresponding to the changed disabled sub-channel bitmap information.

[0232] In the above embodiment, when the disabled sub-channel bitmap information received by the relay device 102 from the access point device 101 changes, the relay device 102 forwards the uplink data frame to the access point device 101 using the puncturing channel pattern corresponding to the changed disabled sub-channel bitmap information, thereby improving the real-time performance of the transmission process and reducing the transmission delay.
