Figure 1 is a schematic diagram of the architecture of a communication system according to an embodiment of the present disclosure.

As shown in Figure 1, the communication system 100 includes a station (STA) 101 and an access point (AP) 102.

In some embodiments, site device 101 includes, 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 at least one of, but is not limited to, a mobile phone, a wearable device, an IoT device that supports WiFi communication, a car with WiFi communication capabilities, a smart car, a tablet computer, a computer with wireless transceiver capabilities, 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.

Specifically, site device 101 can be a terminal device or network device with a Wi-Fi chip. Optionally, site device 101 can 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 the next-generation 802.11 protocol, but is not limited to these.

In some embodiments, the access point device 102 can be an access point for mobile terminals to access a wired network. An AP acts as a bridge connecting wired and wireless networks, its main function being to connect various wireless network clients together and then connect the wireless network to an Ethernet network. Specifically, an AP can be a terminal device or network device with a wireless fidelity chip. Optionally, the AP can support various 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 the next-generation 802.11 protocol, but is not limited to these.

Optionally, in this embodiment of the disclosure, AP and STA can be devices that support multiple connections. For example, they can be represented as Access Point Multi-Link Device (AP MLD) and Non-Access Point Multi-Link Device (Non-AP MLD), respectively. AP MLD can represent an access point that supports multiple connection communication functions, and non-AP MLD can represent a site that supports multiple connection communication functions.

It is understood that the communication system described in this disclosure is for the purpose of more clearly illustrating the technical solutions of this disclosure, and does not constitute a limitation on the technical solutions proposed in this disclosure. As those skilled in the art will know, with the evolution of system architecture and the emergence of new business scenarios, the technical solutions proposed in this disclosure are also applicable to similar technical problems.

The following embodiments of this disclosure can be applied to the communication system 100 shown in FIG1, or to some of the main bodies, but are not limited thereto. The main bodies shown in FIG1 are illustrative. The communication system may include all or some of the main bodies in FIG1, or may include other main bodies outside of FIG1.

The embodiments disclosed herein can be applied to Wireless Local Area Networks (WLANs), such as LANs using the 802.11 series of protocols. In a WLAN, a Basic Service Set (BSS) is a fundamental component. An BSS network consists of site devices with some association within a specific coverage area. One type of association is where sites communicate directly with each other in a self-organizing network; this is called an Independent Basic Service Set (IBSS). Another more common scenario is that in a BSS network, there is only one central site dedicated to managing the BSS, called the Access Point device, and all other STAs in the network are associated with it. Other sites in the BSS network that are not the central site are called terminals, also known as non-AP STAs; terminals and non-AP STAs are collectively referred to as STAs. When describing STAs, it is not necessary to distinguish between APs and non-AP STAs. Within the same BSS network, due to distance, transmission power, etc., a STA cannot detect other STAs that are far away; they are each other's hidden nodes.

Figure 2 is an interactive schematic diagram of a resource identification method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

Step 201, Access Point Device 102 determines a first radio frame; wherein, the first radio frame is used to trigger Site Device STA to transmit uplink trigger-based physical layer protocol data using a hybrid transmission mode of Distributed Resource Unit (dRU) and Conventional Resource Unit (RRU). Unit (Trigger Based Physical Protocol Data Unit, TB PPDU);

The first radio frame includes first identification information, which identifies that: the AP is the bandwidth portion configured by the dRU, and/or the AP is the bandwidth portion configured by the RRU.

In WALN communication scenarios, maximum transmit power and maximum power spectral density may be limited, with the limitation on maximum power spectral density being more stringent than that on maximum transmit power; the maximum transmit power allowed is usually more constrained by power spectral density. Therefore, the transmit power of a single consecutive RU is limited by the maximum power spectral density. dRUs (distant RUs) achieve increased transmit power without changing the power spectral density. Specifically, for dRUs and consecutive RUs containing the same number of subcarriers, the bandwidth spanned by the dRU from the low-frequency start position to the high-frequency end position in the frequency domain is greater than the bandwidth occupied by the consecutive RU. Thus, with the same maximum power spectral density, the total transmit power of the dRU is higher than that of the consecutive RU. In other words, with limited power spectral density, within a certain bandwidth, such as 20MHz, 40MHz, 80MHz, or 160MHz, dispersing a finite number of subcarriers (e.g., the 26 subcarriers contained in a consecutive 26-tone RU) across a wider bandwidth, i.e., more subcarriers (e.g., the odd number of subcarriers in two consecutive 26-tone RUs), can result in increased transmit power. Therefore, compared to continuous RUs, using discrete RUs for data transmission can increase the transmit power of a single RU, thereby increasing the transmit power on a single subcarrier and thus improving the signal-to-noise ratio (SNR).

Compared to dRU, RRU (also known as continuous RU) can be understood as an RU consisting of multiple consecutive subcarriers within a certain bandwidth (20/40/80/160/320MHz); or a continuous RU consisting of two groups of consecutive subcarriers, each group of consecutive subcarriers including multiple consecutive subcarriers, and the two groups of subcarriers are separated only by one or more of the following: guard subcarriers, empty subcarriers, or DC subcarriers.

In this embodiment of the disclosure, the access point device 102 determines a first radio frame, which is used to trigger the STA to transmit uplink TB PPDU using a hybrid dRU and RRU transmission mode. Optionally, the first radio frame may be a trigger frame, a Multi User-Request To Send (MU-RTS) frame, or other newly defined frames. This embodiment of the disclosure does not limit the scope of the first radio frame.

The first radio frame includes first identification information, which identifies that the AP is the bandwidth portion configured for the dRU, and/or that the AP is the bandwidth portion configured for the RRU; that is, the first identification information identifies that the AP is at least one of the bandwidth portions configured for the dRU or the RRU. Specifically, since the RRU is a subcarrier continuously allocated over a certain bandwidth, while the dRU is a subcarrier intermittently allocated over a certain bandwidth (e.g., 26-tone, 52-tone, 106-tone, 242-tone, and 484-tone), in the mixed mode transmission of RRU and dRU, the dRU and RRU may affect each other in the frequency domain position over a certain bandwidth. Therefore, in this embodiment of the disclosure, the bandwidth portions configured for the AP for the dRU and RRU do not overlap in the frequency domain position.

In some embodiments, the uplink bandwidth of the STA is divided into at least two bandwidth portions;

The first identification information includes an identifier corresponding to each of the bandwidth portions.

For example, if the first identification information identifies the bandwidth portion configured for the AP as a dRU, then the portion using RRU transmission can use the remaining bandwidth; or, if the first identification information identifies the bandwidth portion configured for the AP as an RRU, then the portion using dRU transmission can use the remaining bandwidth; furthermore, the first identification information identifies the bandwidth portions configured for both the AP as a dRU and the RRU.

As an example, let's take the bandwidth portion configured for the AP to be identified as an RRU by the first identification information:

For example, if the uplink bandwidth is 20 MHz, the AP can allocate 52-tone or 26-tone DRUs to the STA for uplink transmission, or it may allocate 106-tone DRUs to the STA. The first identification information can then identify which portion of the 20MHz bandwidth is allocated to DRUs for the STA. For example, using a 10MHz allocation granularity and two bits for identification (01 indicating the lower half of the 20MHz bandwidth is allocated to DRUs for the STA), the upper half of the 20MHz bandwidth can be allocated to RRUs for the STA.

For example, if the uplink bandwidth is 40 MHz, the AP can allocate 106-tone, 52-tone, or 26-tone DRUs to the STA for uplink transmission, or it can allocate 242-tone DRUs to the STA. The first identification information can then identify which portion of the 40MHz bandwidth is allocated to DRUs to the STA. For instance, using a 10MHz allocation granularity and 4 bits for identification, 0001 indicates that 10MHz of the 40MHz bandwidth is allocated to DRUs to the STA, and the remaining portion can be allocated to RRUs to the STA.

For example, if the uplink bandwidth is 80 MHz, the AP can allocate 242-tone, 106-tone, 52-tone, and 26-tone DRUs to the STA for uplink transmission. It may also allocate a 106-tone DRU to the STA. In this case, the first identification information can identify which part of the 20MHz bandwidth is allocated to the STA as a DRU. For example, with an allocation granularity of 10MHz, it can be identified using 8 bits, such as 0001000, indicating that 10MHz of the 80MHz bandwidth is allocated as a DRU to the STA; or with an allocation granularity of 20MHz, it can be identified using four bits, such as 0001, indicating that 20MHz of the 80MHz bandwidth is allocated as a DRU.

It is understood that the above examples are only some of the embodiments of this disclosure, and other embodiments are similar to the above embodiments, and will not be repeated here.

Step 202: Access point device 102 sends the first wireless frame.

In this process, the access point device 102 carries first identification information in the first radio frame, using the first identification information to identify whether the AP is the bandwidth portion configured for the dRU, and/or whether the AP is the bandwidth portion configured for the RRU, in order to achieve... Transmission resource identification for the hybrid dRU and RRU transmission mechanism. After receiving the first radio frame, the STA responds to the first radio frame by using both dRU and RRU transmission in the resources identified by the first identification information to complete the uplink data transmission.

In some embodiments, the first identification information is carried in the Special User Info field of the User Info field in the first radio frame;

The Special User Info Field Flag bit in the Common Info field of the first wireless frame indicates that the Special User Info field exists in the User Info field.

The first identification information is carried in the Special User Info field of the User Info field, and the common Info field is set with a Special User Info Field Flag bit. For example, the Special User Info Field Flag bit is set to "0", which indicates that the Special User Info field exists in the User Info field, that is, it indicates that the first identification information exists in the Special User Info field.

Taking the first wireless frame as the trigger as an example, the format of the Common Info field is shown in Table 1 below:

Table 1:

The Special User Info Field Flag bit is located at the 55th bit (B55). Setting the Special User Info Field Flag bit to "0" indicates that the Special User Info field exists in the User Info field. For example, the Special User Info field is located at the 39th bit (B39) of the User Info field.

Furthermore, the User Info field is shown in Table 2 below:

Table 2:

In some embodiments, the first identification information is carried in the reserved bit of the Special User Info field;

The Physical Layer Version Identifier (PHY version Identifier) bit in the Special User Info field indicates that the first radio frame is used to trigger an Ultra-Reliable Receiver PPDU (UHR PPDU).

The uplink bandwidth extension (UL) bit in the Special User Info field is set to the Reserved bit, or it indicates that the extension is not supported.

The format of the Special User Info field is shown in Table 3 below:

Table 3:

For example, setting the PHY version Identifier to 1 indicates that the requested TB PPDU is a UHR PPDU, meaning that dRU allocation is used for transmission; at the same time, setting the UL bandwidth extension field to 0 or reserved indicates that the Special User Info field does not support extensions.

The first identification information is carried in the Reserved bit. For example, if the uplink bandwidth is 20MHz and the allocation granularity is 10MHz, two bits are used for identification. 01 indicates that the lower half of 20MHz is allocated to dRU to STA, and the upper half of 20MHz can be allocated to RRU to STA.

Alternatively, if the uplink bandwidth is 40MHz, with an allocation granularity of 10MHz, and 4 bits are used for identification, 0001 indicates that the 10MHz portion of the 40MHz is allocated to the dRU and then the remaining portion can be allocated to the RRU and then to the STA.

Alternatively, if the uplink bandwidth is 80 MHz, the allocation granularity can be 10 MHz, for example, using 8 bits to identify 10 MHz of the 80 MHz allocated to the STA; or the allocation granularity can be 20 MHz, using four bits to identify 20 MHz of the 80 MHz allocated to the STA.

Step 203: Site device 102 receives the first radio frame.
