Specifically, the AP can be a terminal device or network device with a Wi-Fi 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.

[0139] In some embodiments, the non-AP STA 102 may include, for example, a wireless communication chip, a wireless sensor, or a wireless communication terminal that supports Wi-Fi 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 Wi-Fi communication, a car with Wi-Fi 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.

[0141] Optionally, in this embodiment of the disclosure, the AP can be a device that supports multiple links, for example, it can be represented as an Access Point Multi-Link Device (AP MLD); AP MLD can represent an access point that supports multi-link communication functions.

[0142] 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.

[0143] 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 number and form of each main body are arbitrary. Each main body may be physical or virtual. The connection relationship between the main bodies is illustrative. The main bodies may not be connected or may be connected. The connection can be in any way, it can be a direct connection or an indirect connection, it can be a wired connection or a wireless connection.

[0144] 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 an Access Point (AP) device, while other sites in the BSS network that are not APs are called terminals, also known as non-AP STAs. APs 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.

[0145] Figure 2 is an interactive schematic diagram of a communication method according to an embodiment of the present disclosure. As shown in Figure 2, the method includes:

[0146] Step 201, AP 101 determines a first radio frame; wherein the first radio frame includes first identification information, the first identification information indicating: carrier information of a distributed resource unit (dRU) allocated to the affiliated multi-link site device non-AP STA 102 under a 60MHz bandwidth; the dRU is one or more of a preset distributed resource unit.

[0147] In Wi-Fi technology, the use of large bandwidths (e.g., 80MHz, 160MHz, 320MHz) is gradually becoming the mainstream trend to further improve data transmission rates and support more concurrent connections. However, in the sub-7 GHz band, related technologies impose stricter restrictions on power spectral density (PSD), especially in the 6 GHz low-power indoor (LPI) band (5925MHz–6425MHz). The transmit power limit for non-AP STAs attached to non-AP MLDs is set at approximately -1dBm / MHz. The main reason for this low-power limitation is that, to avoid interference with other devices or services (such as satellite communications and fixed wireless services), the transmit power of the devices is strictly controlled and limited to indoor use. Specifically, devices in the LPI band must be used in indoor environments to reduce interference with other outdoor wireless services. This power limitation means that if the transmit power of a non-AP STAP is concentrated within a narrow, continuous bandwidth, it is easy to reach or exceed the upper limit of the PSD, making it impossible to improve the link signal strength by simply "reducing the bandwidth and concentrating the power". In multi-user uplink transmission (Uplink Orthogonal Frequency Division Multiple Access, UL OFDMA) scenarios based on trigger frames (e.g., UL Triggered Block Physical Protocol Data Unit, UL TB PPDU), it is even more difficult for non-AP STAP to increase transmit power, thus affecting the transmission distance.

[0148] To address the power bottleneck caused by PSD limitations in the LPI band, a distributed radio unit (dRU) concept is proposed. Specifically, access point equipment (APA) can allocate dRUs to site equipment using various dRU formats. These dRUs are used by site equipment to receive Physical Layer Protocol Data Units (PPDUs) in downlink transmissions, allowing multiple site equipment to share spectrum resources simultaneously, thus improving network throughput and transmission distance. dRUs improve signal transmission in two ways: First, by distributing subcarriers discretely across a wider frequency domain (rather than concentrating them in a continuous band), a single STA can significantly reduce the average PSD per unit band, thereby achieving higher total transmit power (Power Boost) under the same constraints and improving signal coverage or communication distance. Second, the distributed subcarrier mode of dRUs can also reduce the peak-to-average power ratio (PAPR) of the transmitted waveform, thereby improving the efficiency of the power amplifier (PA) and achieving higher power gain (Power Boost), further significantly improving uplink transmission performance.

[0149] In related technologies, dRU subcarrier layout designs and corresponding trigger frame signaling indications for bandwidths of 20MHz, 40MHz, and 80MHz have been proposed. However, research has found that when the highest 20MHz band in the 80MHz bandwidth becomes unavailable due to external interference or puncturing, the actual usable bandwidth is only 60MHz. If the traditional "centralized" subcarrier allocation method is still used, allocating subcarriers to a continuous frequency band, the power density (i.e., power per unit bandwidth) of the device in that band is high, easily reaching or exceeding the specified power spectral density (PSD) limit. In contrast, the distributed RU (dRU) allocation method, by distributing subcarriers across a wider frequency domain, results in a lower power density within the band of each subcarrier, thus avoiding reaching the PSD limit and effectively improving total transmit power and signal coverage. Therefore, this disclosure proposes a dRU design for when 20MHz of the 80MHz bandwidth is unavailable (e.g., the highest 20MHz of the 80MHz bandwidth is unavailable, leaving only 60MHz available), and proposes a specific resource indication scheme to solve the power limitation and channel coverage problems in related technologies.

[0150] In this embodiment, the first radio frame includes, but is not limited to, a trigger frame. The first identification information indicates the carrier information of the dRU allocated to the non-AP STA within a 60MHz bandwidth. The dRU is one or more of a preset distributed resource unit. The 60MHz bandwidth can be the working bandwidth for uplink multi-user STA transmission, or a portion of the working bandwidth for uplink multi-user transmission. Specifically, the AP sends a trigger frame to trigger uplink multi-user transmission. The trigger frame carries the carrier information of the dRU allocated to the non-AP STA within the 60MHz bandwidth. After receiving the trigger frame, the non-AP STA transmits an uplink data frame (UL TB PPDU) on the allocated dRU using a TB PPDU. This embodiment improves the dRU carrier resource planning mechanism under 60MHz, avoiding waste of spectrum resources between different devices and improving spectrum utilization efficiency.

[0151] Step 202, AP 101 sends the first radio frame; correspondingly, the non-AP STA 102 receives the first radio frame.

[0152] In this embodiment, the AP sends a first radio frame to ensure that non-AP STAs can accurately receive the carrier information of their assigned dRU, thereby achieving efficient multi-user uplink transmission. This mechanism effectively reduces signal interference, improves the accuracy of resource allocation, and further optimizes transmission efficiency and link stability.

[0153] In some embodiments, under a communication bandwidth of 60MHz, the preset distributed resource unit includes any one or a combination of any of the following:

[0154] 26-tone dRUs (Distributed Resource Units);

[0155] 52-tone distributed resource units (dRUs);

[0156] 106-tone distributed resource units (dRUs);

[0157] 242-tone dRU of distributed resource units.

[0158] In this embodiment of the disclosure, the format (dRU Size) of the dRU allocated by the AP to the non-AP STA under a 60MHz communication bandwidth includes, but is not limited to, 26-tone dRU, 52-tone dRU, 106-tone dRU, and 242-tone dRU.

[0159] In some embodiments, under a 60MHz bandwidth, the preset distributed resource unit includes:

[0160] 26 distributed resource units 26-tone dRU, 52 distributed resource units 52-tone dRU, 106 distributed resource units 106-tone dRU and 242 distributed resource units 242-tone dRU;

[0161] Alternatively, the preset distributed resource unit includes:

[0162] The distributed resource unit 52-tone dRU has 52 units, the distributed resource unit 106-tone dRU has 106 units, and the distributed resource unit 242-tone dRU has 242 units.

[0163] In this embodiment of the disclosure, under a 60MHz communication bandwidth, the minimum size of the distributed resource unit (dRU) allowed for a non-AP STA is 26-tone dRU or 52-tone dRU. Specifically, when the minimum size of the dRU allowed for a non-AP STA is 26-tone dRU, the dRUs allocated by the AP to the non-AP STA include one or more of the following: 26 distributed resource units (26-tone dRU), 52 distributed resource units (52-tone dRU), 106 distributed resource units (106-tone dRU), and 242 distributed resource units (242-tone dRU). When the minimum size of the dRU allowed for a non-AP STA is 52-tone dRU, the dRUs allocated by the AP to the non-AP STA include one or more of the following: 52 distributed resource units (52-tone dRU), 106 distributed resource units (106-tone dRU), and 242 distributed resource units (242-tone dRU).

[0164] In some embodiments, the maximum allocatable number of the 52-tone dRUs at a 60MHz communication bandwidth includes a first number.

[0165] In some embodiments, the maximum allocatable number of the 26-tone dRUs at a 60MHz communication bandwidth includes a second number.

[0166] In some embodiments, the maximum allocatable number of the 106-tone dRUs at a 60MHz communication bandwidth includes a third number.

[0167] In some embodiments, the maximum allocatable number of the 242-tone dRUs at a 60MHz communication bandwidth includes a fourth number.

[0168] The AP allocates 52-tone dRUs to non-AP STAs, with a maximum number of N. N is less than or equal to 12; the value of N is determined based on the total number of subcarriers in a 60MHz band and the number of subcarriers corresponding to different dRU sizes. For example, the maximum number of 52-tone dRUs that can be allocated in a 60MHz communication bandwidth is N. 52 The maximum number of 26-tone dRUs that can be allocated under a 60MHz communication bandwidth is N. 26 The maximum number of 106-tone dRUs that can be allocated under a 60MHz communication bandwidth is N. 106 The maximum number of 242-tone dRUs that can be allocated under a 60MHz communication bandwidth is N. 242 Then, the number of dRUs of different sizes to be allocated must satisfy the following formula:

[0169] Formula 1: N 52 ×52(52 subcarriers)+N 26 ×26(26 subcarriers)+N 106 ×10⁶ (10⁶ subcarriers) + N 242 ×242 (242 subcarriers) ≤ 768 (the total number of subcarriers corresponding to 60MHz is limited).

[0170] For example, the first quantity can be 12, the third quantity can be 6, and the fourth quantity can be 3; or the first quantity can be 6, the third quantity can be 3, and the fourth quantity can be 1; or any other value that satisfies the total number of subcarriers corresponding to 60MHz is applicable to this application and is not limited here.

[0171] For example, the first quantity can be 12, the second quantity can be 27, the third quantity can be 6, and the fourth quantity can be 3. Alternatively, the first quantity can be 6, the second quantity can be 12, the third quantity can be 3, and the fourth quantity can be 1. Any other value that satisfies the limit on the total number of subcarriers corresponding to 60MHz is applicable to this application and is not limited here.

[0172] For example, the dRU allocated by the AP to a non-AP STA under a 60MHz communication bandwidth may include 12 52-tone dRUs, or 6 106-tone dRUs, or 3 242-tone dRUs, or 27 26-tone dRUs, or 10 52-tone dRUs + 3 26-tone dRUs, or 2 242-tone dRUs + 4 52-tone dRUs. Any dRU combination that satisfies Formula 1 above is within the protection scope of this disclosure.

[0173] Step 203: non-AP STA 102 determines at least one allocated dRU based on the first identification information; transmits an uplink Triggered Physical Layer Protocol Data Unit (UL TB PPDU) using the at least one dRU; correspondingly, AP 101 receives the UL TB PPDU.

[0174] In this embodiment of the disclosure, by precisely allocating dRU resource units and using UL TB PPDUs for data transmission, it is ensured that non-access point STAs can efficiently transmit uplink data on designated resource units. This mechanism optimizes spectrum utilization, reduces interference, and improves uplink transmission efficiency.

[0183] The following examples, namely Example 1 and Example 2, will provide a detailed explanation:

[0184] Example 1:

[0185] In this embodiment, every 27 subcarriers are grouped together and then allocated in rounds according to the allocation logic of related technologies. If there are a total of 27 26-tone DRUs within the bandwidth, the total number of resource subcarriers allocated to the 60MHz DBW is 70² = 27 × 26 carriers. The negative frequency portion and the positive frequency portion can be allocated as follows:

[0186] The negative frequency portion to the left of the zero frequency is allocated 17 rounds, meaning the number of resource subcarriers is 459 = 17 × 27. The remaining 9 rounds are allocated to the positive frequency portion to the right, meaning the number of resource subcarriers is 243 = 9 × 27.

[0187] In some embodiments, the maximum number of 26-tone dRUs that can be allocated at a 60MHz bandwidth is N;

[0188] Among them, the resource subcarrier indexes included in the 26-tone dRU with index 1 are: [-474±x: 27: -42±x, 7±y: 27: 223±y];

[0189] Among them, the resource subcarrier index included in each 26-tone dRU with index 2 to N is increased compared to the resource subcarrier index included in the previous 26-tone dRU, and the absolute value of the difference between the resource subcarrier indices included in the 26-tone dRUs of adjacent indices is 1;

[0190] Where N, x, and y are non-negative integers.

[0191] In this embodiment of the disclosure, the carrier information of the distributed resource units (dRUs) allocated to non-AP STAs under a 60MHz bandwidth is shown in Table 1 below:

[0192] Table 1:

[0193] Assuming the maximum allocatable number of 26-tone dRUs under a 60MHz bandwidth is 27, the indices of the 26-tone dRUs disclosed in this embodiment include 1 to 27, and their corresponding 26-tone DRU numbers in Table 1 are as follows: [1,19,10,6,24,15,|3,21,12,8,26,17,||2,20,11,7,25,16,|4,22,13,9,27,18||5,14,23]. See below for details:

[0194] The resource subcarrier index included in the 26-tone dRU with index 1 is: [-474:27:-42,7:27:223], that is, the left half (negative index part) and the right half (positive index part) select 1 subcarrier every 27 subcarriers according to the step size;

[0206] The resource subcarrier index included in the 26-tone dRU with index 13 is: [-462:27:-30,19:27:235];

[0207] The resource subcarrier index included in the 26-tone dRU with index 14 is: [-461:27:-29,20:27:236];

[0208] The resource subcarrier index included in the 26-tone dRU with index 15 is: [-460:27:-28,21:27:237];

[0212] The resource subcarrier index included in the 26-tone dRU with index 19 is: [-456:27:-24,25:27:241];

[0213] The resource subcarrier index included in the 26-tone dRU with index 20 is: [-455:27:-23,26:27:242];

[0214] The resource subcarrier indexes included in the 26-tone dRU with index 21 are: [-454:27:-22,27:27:243];

[0215] The resource subcarrier index included in the 26-tone dRU with index 22 is: [-453:27:-21,28:27:244];

[0216] The resource subcarrier index included in the 26-tone dRU with index 23 is: [-452:27:-20,29:27:245];

[0220] The resource subcarrier index included in the 26-tone dRU with index 27 is: [-448:27:-16,33:27:249].

[0221] It should be noted that in this embodiment, the subcarrier allocation comprises two independent left and right blocks. The number of empty subcarriers near the central zero frequency can be flexibly changed, and the number of subcarriers at the spectrum edges on both sides can also be flexibly changed according to the left and right shift of the specific allocated data subcarrier blocks. For example, the subcarriers on the left side of the central zero frequency can be shifted left or right by x positions (x = 1, 2, 3, ...), and the subcarriers on the right side of the central zero frequency can be shifted left or right by y positions (x = 1, 2, 3, ...). For example, all allocated subcarriers in the negative frequency part can be uniformly shifted left by 1 position, thus reducing the sequence number of all subcarriers in the negative frequency part table by 1, but their relative dRU number remains unchanged. For example, 26-tone dRU1 becomes [-475:27:-43,7:27:223]. Similarly, the positive frequency part can also be uniformly shifted left and right, while the positive and negative frequency parts can be shifted independently. The above-mentioned left and right shifting principle also applies to subsequent embodiments, and will not be repeated here.

[0222] In some embodiments, the maximum number of 52-tone dRUs that can be allocated at a bandwidth of 60MHz is M;

[0223] Among them, the resource subcarrier indices included in the 52-tone dRU with index 1 are: [-474±x:27:-42±x,7±y:27:223±y], [-462±x:27:-30±x,19±y:27:235±y] or,

[0224] The resource subcarrier indices included in the 52-tone dRU with index 1 are: [-499±x:27:-40±x,22±y:27:211±y], [-487±x:27:-28±x,34±y:27:223±y];

[0225] Among them, the resource subcarrier index included in each 52-tone dRU with indices 2 to M is increased compared to the resource subcarrier index included in the previous 52-tone dRU, and the absolute value of the difference between the resource subcarrier indices included in the 52-tone dRUs of adjacent indices is 1.

[0226] Where M, x, and y are non-negative integers.

[0227] Assuming the maximum allocatable number of 52-tone dRUs in a 60MHz bandwidth is 12, the resource subcarrier distribution of the 52-tone dRUs can be understood as being formed by "interleaving" two 26-tone dRU patterns, meaning the two 26-tone dRU subsets are distributed in a staggered, interleaved manner in the spectrum. This distributed splicing makes the spectral coverage of the 52-tone dRUs denser, while still maintaining good uniformity. For example, 52-tone dRU1 is composed of two sets of 26-tone dRUs (i.e., "dRU1" and "dRU2" in the table), and their corresponding 52-tone dRU numbers in Table 1 are: [1,9,5,3,11,7,|2,10,6,4,12,8]. See below for details:

[0228] The resource subcarrier index included in the 52-tone dRU with index 1 is: 26-tone[dRU1~2], which is the union of dRU1 and dRU in Table 1: [-474:27:-42,7:27:223]∪[-462:27:-30,19:27:235];

[0229] The resource subcarrier index included in the 52-tone dRU with index 2 is: 26-tone[dRU19~20], that is: [-473:27:-41,8:27:224]∪[-461:27:-29,20:27:236];

[0230] The resource subcarrier index included in the 52-tone dRU with index 3 is: 26-tone[dRU10~11], that is: [-472:27:-40,9:27:225]∪[-460:27:-28,21:27:237];

[0231] The resource subcarrier index included in the 52-tone dRU with index 4 is: 26-tone[dRU6~7], that is: [-471:27:-39,10:27:226]∪[-459:27:-27,22:27:238];

[0232] The resource subcarrier index included in the 52-tone dRU with index 5 is: 26-tone[dRU24~25], that is: [-470:27:-38,11:27:227]∪[-458:27:-26,23:27:239];

[0233] The resource subcarrier index included in the 52-tone dRU with index 6 is: 26-tone[dRU15~16], that is: [-469:27:-37,12:27:228]∪[-457:27:-25,24:27:240];

[0234] The resource subcarrier index included in the 52-tone dRU with index 7 is: 26-tone[dRU3~4], that is: [-468:27:-36,13:27:229]∪[-456:27:-24,25:27:241];

[0235] The resource subcarrier index included in the 52-tone dRU with index 8 is: 26-tone[dRU21~22], that is: [-467:27:-35,14:27:230]∪[-455:27:-23,26:27:242];

[0236] The resource subcarrier index included in the 52-tone dRU with index 9 is: 26-tone [dRU12~13], that is: [-466:27:-34,15:27:231]∪[-454:27:-22,27:27:243];

[0237] The resource subcarrier index included in the 52-tone dRU with index 10 is: 26-tone[dRU8~9], that is: [-465:27:-33,16:27:232]∪[-453:27:-21,28:27:244];

[0238] The resource subcarrier index included in the 52-tone dRU with index 11 is: 26-tone[dRU26~27], that is: [-464:27:-32,17:27:233]∪[-452:27:-20,29:27:245].

[0239] The resource subcarrier index included in the 52-tone dRU with index 12 is: 26-tone[dRU17~18], that is: [-463:27:-31,18:27:234]∪[-451:27:-19,30:27:246].

[0240] In some embodiments, the maximum number of 106-tone dRUs that can be allocated at a 60MHz bandwidth is H;

[0241] Among them, the resource subcarrier indices included in the 106-tone dRU with index 1 are: [-474±x:27:-42±x,7±y:27:223±y], [-462±x:27:-30±x,19±y:27:235±y], [-468±x:27:-36±x,13±y:27:229±y], [-456±x:27:-24±x,25±y:27:241±y]; or,

[0242] The resource subcarrier indices included in the 106-tone dRU with index 1 are: [-499±x:27:-40±x,22±y:27:211±y], [-487±x:27:-28±x,34±y:27:223±y], [-493±x:27:-34±x,28±y:27:217±y], [-481±x:27:-22±x,40±y:27:229±y];

[0243] Among them, the resource subcarrier index included in each 106-tone dRU from index 2 to H is increased compared to the resource subcarrier index included in the previous 106-tone dRU, and the absolute value of the difference between the resource subcarrier indices included in the 106-tone dRUs of adjacent indices is 1.

[0244] Where H, x, and y are non-negative integers.

[0245] In this case, it is assumed that the maximum number of 106-tone dRUs that can be allocated under a 60MHz bandwidth is 6.

[0246] A 106-tone dRU consists of four 26-tone dRUs supplemented with two spectrum edge subcarriers, or zero-frequency edge subcarriers. It is also equivalent to two 52-tone dRUs supplemented with two spectrum edge subcarriers, or zero-frequency edge subcarriers. For example, 106-tone dRU1 is composed of four groups of 26-tone dRUs (i.e., “dRU1”, “dRU2”, “dRU3”, and “dRU4” in Table 1) and edge subcarriers. For example, the resource subcarrier index of the 106-tone dRU with index 1 is 52-tone[dRU1]∪52-tone[dRU2]∪[m,n]; where m and n are non-positive integers, the interval between m and n is 6, and the interval between n and -474±x is 6. The 52-tone dRUs corresponding to the indices of the 106-tone dRUs are listed in Table 1 as [1, 5, 3, 2, 6, 4]. That is, the 106-tone dRU with index 1 corresponds to 106-tone dRU1 in Table 1, the 106-tone dRU with index 2 corresponds to 106-tone dRU5 in Table 1, and so on. For example:

[0247] The resource subcarrier indices included in the 106-tone dRU with index 1 are: 52-tone [DRU1~2], [-486, -480];

[0248] The resource subcarrier indices included in the 106-tone dRU with index 2 are: 52-tone[DRU3~4],[-483,-477];

[0249] The resource subcarrier indices included in the 106-tone dRU with index 3 are: 52-tone [DRU5~6], [-484, -478];

[0250] The resource subcarrier indices included in the 106-tone dRU with index 4 are: 52-tone [DRU7~8], [-481, -475];

[0251] The resource subcarrier indices included in the 106-tone dRU with index 5 are: 52-tone[DRU9~10],[-485,-479];

[0252] The resource subcarrier indices included in the 106-tone dRU with index 6 are: 52-tone[DRU11~12],[-482,-476].

[0253] It should be noted that the resource subcarrier indexes in Table 1 can be shifted to the left or right in a uniform manner. For example, the 26-tone dRU in Table 1 can be uniformly shifted left by x positions, becoming: [-474-x:27:-42-x,7-x:27:223-x]; another example is that the 26-tone dRU in Table 1 can be uniformly shifted right by y positions, becoming: [-474+y:27:-42+y,7+y:27:223+y]; yet another example is that the left half of the resource subcarrier index of the 26-tone dRU in Table 1 is shifted left by x positions, while the right half remains unchanged, becoming: [-474-x:27:-42-x,7:27:223]; yet another example is that the left half of the resource subcarrier index of the 26-tone dRU in Table 1 remains unchanged, while the right half is shifted right by y positions, becoming: [-474:27:-42,7+y:27:223+y]; yet another example is that the 26-tone dRU in Table 1... The resource subcarrier index of the dRU is shifted left by x positions and right by y positions, becoming: [-474-x:27:-42-x,7+y:27:223+y]. For example, the resource subcarrier index of the 26-tone dRU in Table 1 is shifted left by x positions and right by y positions, becoming: [-474+x:27:-42+x,7-y:27:223-y]. This is not an exhaustive list.

[0254] In some embodiments,

[0255] The maximum number of 242-tone dRUs that can be allocated under a 60MHz bandwidth is I;

[0256] Among them, the resource subcarrier indices included in the 242-tone dRU with index 1 are: [-474±x:27:-42±x, 7±y:27:223±y], [-462±x:27:-30±x, 19±y:27:235±y], [-468±x:27:-36±x, 13±y:27:229±y], [-456±x:27:-24±x, 25±y:27:241±y], [-471±x:27... [-39±x,10±y:27:226±y], [-459±x:27:-27±x,22±y:27:238±y], [-465±x:27:-33±x,16±y:27:232±y], [-453±x:27:-21±x,28±y:27:244±y], [-450±x:27:-18±x,31±y:27:247±y]; or,

[0257] The resource subcarrier indices included in the 242-tone dRU with index 1 are: [-499±x:27:-40±x, 22±y:27:211±y], [-487±x:27:-28±x, 34±y:27:223±y], [-493±x:27:-34±x, 28±y:27:217±y], [-481±x:27:-22±x, 40±y:27:229±y], [-496±x: [27:-37±x,25±y:27:214±y], [-484±x:27:-25±x,37±y:27:226±y], [-490±x:27:-31±x,31±y:27:220±y], [-478±x:27:-19±x,43±y:27:232±y], [-475±x:27:-16±x,46±y:27:235±y];

[0258] Among them, the resource subcarrier index included in each 242-tone dRU with index 2 to I is increased compared to the resource subcarrier index included in the previous 242-tone dRU, and the absolute value of the difference between the resource subcarrier indices included in the 242-tone dRUs of adjacent indices is 1;

[0259] Where I, x, and y are non-negative integers.

[0260] Assuming the maximum allocatable number of 242-tone dRUs in a 60MHz bandwidth is 3, each 242-tone dRU consists of two 106-tone dRUs and a 'center' 26-tone dRU, supplemented by four additional subcarriers near the spectrum edge or zero frequency. For example, in Table 1, 242-tone dRU1 consists of 106-tone dRU1, 106-tone dRU2, and the 'center' 26-tone dRU5, supplemented by edge subcarriers [-m:3:-n]; 242-tone dRU2 consists of 106-tone dRU3, 106-tone dRU4, and the 'center' 26-tone dRU23, supplemented by edge subcarriers [m:3:n]. Where m and n are non-positive integers, the edge subcarriers are expanded to [m, m+3, m+6, n]; where n = m+9; the value of n is determined according to the resource subcarrier indices included in 106-tone dRU1 in Table 1. For example, if the resource subcarrier indices included in 106-tone dRU1 in Table 1 are: 52-tone [DRU1~2], [-486, -480], then n = -489, m = -498. The 106-tone dRU numbers corresponding to the indices of the 106-tone dRUs are [1, 3, 2] in Table 1, that is, the 106-tone dRU with index 1 is 242-tone dRU1 in Table 1, and the 106-tone dRU with index 2 is 242-tone dRU3 in Table 1, as shown below:

[0261] The resource subcarrier indices included in the 242-tone dRU with index 1 are: 106-tone dRU1∪106-tone dRU2∪26-tone dRU5∪[-498:3:-489];

[0262] The resource subcarrier indices included in the 242-tone dRU with index 2 are: 106-tone dRU5∪106-tone dRU6∪26-tone dRU14∪[-497:3:-488;

[0263] The resource subcarrier index included in the 242-tone dRU with index 3 is: 106-tone dRU3∪106-tone dRU4∪26-tone dRU23∪[-496:3:-487.

[0264] In some embodiments, every 27 subcarriers are grouped together and then allocated in rounds according to the allocation logic of the relevant technology. If there are a total of 27 26-tone DRUs within the bandwidth, the total number of resource subcarriers allocated to the 60MHz DBW is 70² = 27 × 26 carriers. The negative frequency portion and the positive frequency portion can be allocated as follows:

[0265] The negative frequency portion to the left of the zero frequency is allocated 18 rounds, meaning the number of resource subcarriers is 486 = 18 × 27. The remaining 8 rounds are allocated to the positive frequency portion to the right, meaning the number of resource subcarriers is 216 = 8 × 27.

[0266] In this embodiment of the disclosure, the carrier information of the distributed resource units (dRUs) allocated to non-AP STAs under a 60MHz bandwidth is shown in Table 2 below:

[0267] Table 2:

[0268] Assuming the maximum allocatable number of 26-tone dRUs in a 60MHz bandwidth is 27, the indexes of the 26-tone dRUs disclosed in this embodiment include 1 to 27, and their corresponding 26-tone DRU numbers in Table 2 are: [1,10,19,6,15,24,|3,12,21,8,17,26,||2,11,20,7,16,25,|4,13,22,9,18,27||5,14,23]. It is understood that the indexes of different dRU formats in this embodiment, and the resource subcarrier indexes they include, can be obtained from Table 2 using the above method, and will not be elaborated upon here.

[0269] Example 2:

[0270] In this embodiment of the disclosure, when allocating 26-tone dRU resource subcarriers, it is assumed that the number of resource subcarriers on the left is 486, with the index of the left resource subcarrier being [-499:-14], and the index of the 216 resource subcarriers on the right being [22:237]. Then, the leftmost 27 subcarriers of the first round of the 27 26-tone dRUs are numbered [-499:-473], and their corresponding 26-tone dRU numbers in Table 3 are as follows: [1,10,19,6,15,24,|3,12,21,8,17,26,||2,11,20,7,16,25,|4,13,22,9,18,27||5,14,23].

[0271] Table 3:

[0272] In some embodiments, the maximum number of 26-tone dRUs that can be allocated at a 60MHz bandwidth is N;

[0273] Among them, the resource subcarrier indexes included in the 26-tone dRU with index 1 are: [-499±x: 27: -40±x, 22±y: 27: 211±y];

[0274] Among them, the resource subcarrier index included in each 26-tone dRU with index 2 to N is increased compared to the resource subcarrier index included in the previous 26-tone dRU, and the absolute value of the difference between the resource subcarrier indices included in the 26-tone dRUs of adjacent indices is 1;

[0275] Where N, x, and y are non-negative integers.

[0276] In some embodiments, the maximum number of 52-tone dRUs that can be allocated at a bandwidth of 60MHz is M;

[0277] The resource subcarrier indices included in the 52-tone dRU with index 1 are: [-499±x:27:-40±x,22±y:27:211±y], [-487±x:27:-28±x,34±y:27:223±y];

[0278] Among them, the resource subcarrier index included in each 52-tone dRU with indices 2 to M is increased compared to the resource subcarrier index included in the previous 52-tone dRU, and the absolute value of the difference between the resource subcarrier indices included in the 52-tone dRUs of adjacent indices is 1.

[0279] Where M, x, and y are non-negative integers.

[0280] In some embodiments, the maximum number of 106-tone dRUs that can be allocated at a 60MHz bandwidth is H;

[0281] in,

[0282] The resource subcarrier indices included in the 106-tone dRU with index 1 are: [-499±x:27:-40±x,22±y:27:211±y], [-487±x:27:-28±x,34±y:27:223±y], [-493±x:27:-34±x,28±y:27:217±y], [-481±x:27:-22±x,40±y:27:229±y];

[0283] Among them, the resource subcarrier index included in each 106-tone dRU from index 2 to H is increased compared to the resource subcarrier index included in the previous 106-tone dRU, and the absolute value of the difference between the resource subcarrier indices included in the 106-tone dRUs of adjacent indices is 1.

[0284] Where H, x, and y are non-negative integers.

[0285] In some embodiments, the maximum number of 242-tone dRUs that can be allocated at a 60MHz bandwidth is I;

[0286] in,

[0287] The resource subcarrier indices included in the 242-tone dRU with index 1 are: [-499±x:27:-40±x, 22±y:27:211±y], [-487±x:27:-28±x, 34±y:27:223±y], [-493±x:27:-34±x, 28±y:27:217±y], [-481±x:27:-22±x, 40±y:27:229±y], [-496±x: [27:-37±x,25±y:27:214±y], [-484±x:27:-25±x,37±y:27:226±y], [-490±x:27:-31±x,31±y:27:220±y], [-478±x:27:-19±x,43±y:27:232±y], [-475±x:27:-16±x,46±y:27:235±y];

[0288] Among them, the resource subcarrier index included in each 242-tone dRU with index 2 to I is increased compared to the resource subcarrier index included in the previous 242-tone dRU, and the absolute value of the difference between the resource subcarrier indices included in the 242-tone dRUs of adjacent indices is 1;

[0289] Where I, x, and y are non-negative integers.

[0290] It is understood that the indexes of different dRU formats in the embodiments of this disclosure, as well as the resource subcarrier indexes they include, can be read from Table 3 in the manner described above, and will not be repeated here.

[0291] In some embodiments, when allocating 26-tone DRU resource subcarriers, the number of resource subcarriers on the left is 486, assuming that the index of the left resource subcarrier is [-499:-14], and the index of the 216 resource subcarriers on the right is [22:237]. Then the leftmost 27 subcarriers of the first round of 27 26-tone DRUs are numbered [-499:-473], and their corresponding 26-tone DRU numbers are shown in Table 4 below as follows: [1,19,10,6,24,15,|3,21,12,8,26,17,||2,20,11,7,25,16,|4,22,13,9,27,18||5,14,23].

[0292] Table 4:

[0293] It is understood that the indexes of different dRU formats in the embodiments of this disclosure, as well as the resource subcarrier indexes they include, can be read from Table 4 in the manner described above, and will not be repeated here.

[0294] It should be noted that when the preset distributed resource unit does not include 26-tone dRU under a 60MHz communication bandwidth, the 26-tone dRU part can be removed from any of the tables from Table 1 to Table 4, but the index corresponding to each of the other dRUs and their own index numbers remain unchanged.

[0295] The communication method provided in this disclosure will be specifically described below through Example 3:

[0296] Example 3:

[0297] Related technologies disclose dRU resource subcarrier layout designs for 20MHz, 40MHz, and 80MHz bandwidths, but currently, dRU resource subcarrier layouts for 60MHz bandwidth are not included. For example, different distributed bandwidths (DBWs) use corresponding dRUs for 20MHz, 40MHz, and 80MHz bandwidths:

[0298] A 20MHz DBW can use 26 / 52 / 106-tone dRUs.

[0299] A 40MHz DBW can use 26 / 52 / 106 / 242-tone dRUs.

[0300] An 80MHz DBW can use 52 / 106 / 242 / 484-tone dRUs.

[0301] For distributed bandwidths (DBW) of 20MHz, 40MHz, and 80MHz, the current standard draft has defined the maximum number of dRUs of various sizes that each DBW can contain, as shown in Table 5 below:

[0302] Table 5:

[0303] As mentioned above, the application scenario for dRU is multi-user uplink transmission (UL OFDMA) of non-AP STA based on trigger frames, specifically the frame type UL TB PPDU. Related technologies define the distributed bandwidth (DBW) of UHR UL TB PPDU as 20, 40, 60, and 80 MHz. If preamble puncturing is applied to the highest 20 MHz of the 80 MHz band, a 60 MHz DBW scenario will occur.

[0304] Currently, relevant technologies have specified the carrier tone plan and corresponding pilot allocation design for 20MHz, 40MHz, and 80MHz DBW. The tone plan for the dRU under 20MHz and 40MHz DBW is designed based on a 26-tone dRU as the basic building block, while the dRU under 80MHz DBW is designed based on a 52-tone dRU as the basic building block. The carrier tone plan and corresponding pilot allocation design of the dRU retain the same hierarchical subcarrier structure as the conventional RU (RRU). For example, the overall design logic is as follows:

[0305] A 26-tone dRU consists of 24 data subcarriers and 2 pilot subcarriers;

[0306] A 52-tone dRU consists of 48 data subcarriers and 4 pilot subcarriers, and a 52-tone dRU is composed of two corresponding 26-tone dRUs.

[0307] For example: a 52-tone dRU1 consists of all subcarriers of 26-tone dRU1 and 26-tone dRU2; a 106-tone dRU consists of 102 data subcarriers and 4 pilot subcarriers; a 106-tone dRU is formed by combining two corresponding 52-tone dRUs with two additional subcarriers. For example, 106-tone dRU1 consists of 52-tone dRU1, 52-tone dRU2, and two additional subcarriers. A 242-tone dRU consists of 234 data subcarriers and 8 pilot subcarriers; a 242-tone dRU is formed by combining two corresponding 106-tone dRUs, one 26-tone dRU, and four additional subcarriers. For example, a 242-tone dRU1 consists of 106-tone dRU1, 106-tone dRU2, 26-tone dRU5, and 4 additional subcarriers; a 484-tone dRU consists of 468 data channels and 16 pilot subcarriers, and a 484-tone dRU is formed by combining two corresponding 242-tone dRUs; for example, a 484-tone dRU1 consists of all the subcarriers of 242-tone dRU1 and 242-tone dRU2.

[0308] In some embodiments, the carrier allocation design corresponding to a 20MHz DBW as specified in the relevant technologies is shown in Table 6 below:

[0309] Table 6:

[0310] As shown in Table 6, subcarriers are numbered with a center frequency (DC) of 0. Negative indices represent subcarriers with frequencies below the center frequency, and positive indices represent subcarriers with frequencies above the center frequency. For example, -120:9:-12 means starting from -120, one subcarrier is selected every nine subcarriers, up to -12. Expanding this sequence, we get the subcarrier index set on the negative frequency band side: {-120,-111,-102,-93,-84,-75,-66,-57,-48,-39,-30,-21,-12}. Since the entire RU is symmetrically distributed across the spectrum, the positive frequency side corresponds to a symmetrical index set: {12,21,30,39,48,57,66,75,84,93,102,111,120}; where 0 represents a DC subcarrier, which does not carry data. From this combination, we can see that a 26-tone dRU occupies a total of 26 discrete subcarriers (13 in the negative band and 13 in the positive band), roughly evenly distributed throughout the 20MHz channel. This logic applies to the subcarrier distribution of all subsequent dRUs, and will not be elaborated further.

[0311] The 26-tone dRU distribution comprises 26 subcarriers, including 24 data subcarriers and 2 pilot subcarriers. These subcarriers do not occupy a continuous block of the spectrum but are distributed across the entire frequency band with a fixed step size. It can be viewed as 26 subcarrier points roughly "spread" evenly across the spectrum, with the left half (negative index portion) and the right half (positive index portion) selecting one subcarrier every nine subcarriers according to a step size. It should be noted that when all 26-tone dRUs are allocated, 7 subcarriers are left empty at the edge of the negative frequency section on the left as the left spectrum protection interval: {-128,-127,-126,-125,-124,-123,-122,-121}, and 6 subcarriers are left empty at the positive frequency section on the right as the right spectrum protection interval: {121,122,123,124,125,126,127}. Meanwhile, 7 subcarriers are left empty near the central DC zero frequency: {-3,-2,-1,0,1,2,3}.

[0312] Among them, 26-tone dRU1 and 26-tone dRU2 can form 52-tone dRU2, while 26-tone dRU1 to 26-tone dRU4 can form the main body of 106-tone dRU1. Therefore, a dRU carrier is selected from the leftmost subcarrier index for allocation cycle: {-120,-119,-118,-117,-116,-115,-114,-113,-112}, and its corresponding 26-tone dRU sequence numbers are {1,6,3,8,2,7,4,9,5} in sequence. Since 26-tone dRU5 does not participate in the composition of 52-tone dRU and 106-tone dRU, according to this numbering, 26-tone dRU1 and 26-tone dRU2 form the approximately uniformly discrete 52-tone dRU2, while 26-tone dRU1 to 26-tone dRU4 form the main part of the approximately uniformly discrete 106-tone dRU1.

[0313] 52-tone dRU distribution: This can be understood as being formed by "interleaving" two 26-tone dRU patterns, meaning that the two 26-tone dRU subsets are distributed in a staggered, interleaved manner in the spectrum. This distributed splicing makes the spectral coverage of the 52-tone dRU denser, while still maintaining good uniformity. For example, 52-tone dRU1 is composed of two sets of 26-tone dRUs (i.e., "dRU1" and "dRU2" in the table). It should be noted that 26-tone dRU5 does not participate in the composition of the 52-tone dRU, similar to how the central 26-tone RU in the RU of related technologies does not participate in the composition of the 52-tone dRU.

[0314] The index set of 26-tone dRU1 is {-120:9:-12}∪{6:9:114}

[0315] Negative frequency range: {-120,-111,-102,-93,-84,-75,-66,-57,-48,-39,-30,-21,-12}

[0316] Positive frequency range: {6,15,24,33,42,51,60,69,78,87,96,105,114}

[0317] The index set of 26-tone dRU2 is {-116:9:-8}∪{10:9:118}

[0318] Negative frequency range: {-116,-107,-98,-89,-80,-71,-62,-53,-44,-35,-26,-17,-8}

[0319] Positive frequency range: {10,19,28,37,46,55,64,73,82,91,100,109,118}

[0320] The index set of 52-tone dRU1: 26-tone[dRU1, dRU2]

[0321] Negative frequency range: {-120,-116,-111,-107,-102,-98,-93,-89,-84,-80,-75,-71,-66,-62,-57,-53,-48,-44,-39,-35,-30,-26,-21,-17,-12,-8}

[0322] Positive frequency range: {6,10,15,19,24,28,33,37,42,46,51,55,60,64,69,73,78,82,87,91,96,100,105,109,114,118}

[0323] As can be seen from the above index, the negative and positive frequency portions of the 52-tone dRU1 index are not distributed separately across the entire frequency band with a fixed step size, but rather are interleaved with approximately uniform distribution across the positive and negative frequencies using steps of 4 and 5. Meanwhile, the 26-tone dRU5 is not involved in the construction of the 52-tone dRU.

[0324] 106-tone dRU distribution: A 106-tone dRU consists of four 26-tone dRUs simultaneously supplementing two subcarriers near the DC frequency, which is equivalent to two 52-tone dRUs simultaneously supplementing two subcarriers near the DC frequency. For example, 106-tone dRU1 is composed of four groups of 26-tone dRUs (i.e., "dRU1", "dRU2", "dRU3", and "dRU4" in Table 6) combined with {-3,3}. It can be seen that when all 106-tone dRUs are allocated, five subcarriers near the central DC zero frequency are left empty: {-2,-1,0,1,2}.

[0325] The index set of 106-tone dRU1 is: 26-tone[dRU1,dRU2,dRU3,dRU4]∪{-3,3}.

[0326] Negative frequency range: {-120,-118,-116,-114,-111,-109,-107,-105,-102,-100,-98,-96,-93,-91,-89,-87,-84,-82,-80,-78,-75,-73,-71,-69,-66,-64,-62,-60,-57,-55,-53,-51,-48,-46,-44,-42,-39,-37,-35,-33,-30,-28,-26,-24,-21,-19,-17,-15,-12,-10,-8,-6,-3};

[0327] Positive frequency range: {3,6,8,10,12,15,17,19,21,24,26,28,30,33,35,37,39,42,44,46,48,51,53,55,57,60,62,64,66,69,71,73,75,78,80,82,84,87,89,91,93,96,98,100,102,105,107,109,111,114,116,118,120};

[0328] The index set of 106-tone dRU2 is: 26-tone[dRU6,dRU7,dRU8,dRU9]∪{-2,2};

[0329] Negative frequency range: {-119,-117,-115,-113,-110,-108,-106,-104,-101,-99,-97,-95,-92,-90,-88,-86,-83,-81,-79,-77,-74,-72,-70,-68,-65,-63,-61,-59,-56,-54,-52,-50,-47,-45,-43,-41,-38,-36,-34,-32,-29,-27,-25,-23,-20,-18,-16,-14,-11,-9,-7,-5,-2};

[0330] Positive frequency range: {2,4,7,9,11,13,16,18,20,22,25,27,29,31,34,36,38,40,43,45,47,49,52,54,56,58,61,63,65,67,70,72,74,76,79,81,83,85,88,90,92,94,97,99,101,103,106,108,110,112,115,117,119}.

[0331] In some embodiments, the carrier allocation design corresponding to a 40MHz DBW as specified in the relevant technologies is shown in Table 7 below:

[0332] Table 7:

[0333] The 26-tone dRU distribution comprises 26 subcarriers, including 24 data subcarriers and 2 pilot subcarriers. The subcarrier distribution logic is similar to the 20MHz DBW case. The number of 26-tone dRUs in a 40MHz DBW bandwidth is twice that in a 20MHz DBW bandwidth, resulting in a total of 18 26-tone dRUs, numbered from dRU1 to dRU18. It should be noted that when all 26-tone dRUs are allocated, 14 subcarriers are left empty at the edge of the negative frequency portion on the left as a left-side spectrum protection interval: {-256,-255,…,-244,-243}. Similarly, 12 subcarriers are left empty at the positive frequency portion on the right as a right-side spectrum protection interval: {244,245,…,255}. Finally, 18 subcarriers are left empty near the central DC zero frequency: {-8,-7,…,-1}∪{0}∪{1,2,…,9}.

[0334] Under a 40MHz DBW bandwidth, the numbering pattern of the 26-tone dRUs is consistent with that of the 20MHz DBW bandwidth, allowing 26-tone dRU1 and 26-tone dRU2 to form 52-tone dRU2, while 26-tone dRU1 to 26-tone dRU4 form the main body of 106-tone dRU1. Furthermore, 106-tone dRU1 and 106-tone dRU2 form the main body of 242-tone dRU1. Similarly, a dRU carrier allocation cycle is taken from the leftmost subcarrier index: {-242:-225}, and its corresponding 26-tone dRU numbers are {1,10,6,15,3,12,8,17,14,2,11,7,16,4,13,9,18,5}. Since 26-tone dRU5 and 26-tone dRU14 do not participate in the composition of 52-tone dRU and 106-tone dRU, according to this numbering allocation, 26-tone dRU1 and 26-tone dRU2 exactly form the approximately uniformly discrete distribution of 52-tone dRU2, while 26-tone dRU1 to 26-tone dRU4 exactly form the main part of the approximately uniformly discrete distribution of 106-tone dRU1. It should be noted here that 242-tone dRU1 is mainly composed of 106-tone dRU1 and 106-tone dRU2, with 26-tone dRU5 added at the same time.

[0335] The 52-tone dRU distribution, as shown in the index in Table 7, can be understood as being composed of two 26-tone dRU patterns "interleaved" under a 40MHz DBW bandwidth. That is, the two 26-tone dRU subsets are distributed in a staggered, interleaved manner in the spectrum. For example, 52-tone dRU1 is composed of two sets of 26-tone dRUs (i.e., "dRU1" and "dRU2" in the table). It should be noted that 26-tone dRU5 and 26-tone dRU14 do not participate in the composition of the 52-tone dRU, similar to how the two central 26-tone RUs with 20MHz DBW bandwidths in an RU do not participate in the composition of the 52-tone RU.

[0336] The 106-tone dRU distribution consists of four 26-tone dRUs supplementing two subcarriers near the DC frequency, which is equivalent to two 52-tone dRUs supplementing two subcarriers near the DC frequency. For example, 106-tone dRU1 is composed of four groups of 26-tone dRUs (i.e., "dRU1", "dRU2", "dRU3", and "dRU4" in Table 7) combined with {-8, 5}. It can be seen that when all 106-tone dRUs are allocated, after removing the remaining unused subcarriers, nine subcarriers near the central DC zero frequency are left empty: {-4, -3, -2, -1, 0, 1, 2, 3, 4}.

[0337] The 242-tone dRU is distributed as follows: Each 242-tone dRU consists of two 106-tone dRUs and a central 26-tone dRU, supplemented by four additional subcarriers near the spectrum edge or zero frequency. For example, 242-tone dRU1 consists of 106-tone dRU1, 106-tone dRU2, and a central 26-tone dRU5, supplemented by central subcarriers {-4, 3, 9} and edge subcarriers {-244}; 242-tone dRU2 consists of 106-tone dRU3, 106-tone dRU4, and a central 26-tone dRU14, supplemented by central subcarriers {-3, 4} and edge subcarriers {-243, 244}. Therefore, when all 242-tone dRUs are allocated, five subcarriers near the central DC zero frequency are left unused: {-2, -1, 0, 1, 2}. Eleven subcarriers are left empty at the edge of the negative frequency portion on the left as the left spectrum protection interval: {-256,-255,…,-246,-245}, while eleven subcarriers are left empty at the edge of the positive frequency portion on the right as the right spectrum protection interval: {245,246,…,255}.

[0338] In some embodiments, the carrier allocation design corresponding to the 80MHz DBW specified in the relevant technology is shown in Table 8 below:

[0339] Table 8:

[0340] The 52-tone dRU distribution, as seen in the indexes in Table 8, is such that since there is no 26-tone dRU under an 80MHz DBW bandwidth, the 52-tone dRU can be understood as being formed by "interleaving" two virtual 26-tone dRU patterns. For example, 52-tone dRU1 consists of two sets of indexes: [-483:36:-51,17:36:449]∪[-467:36:-35,33:36:465]. These two sets of indexes can be regarded as two virtual 26-tone dRU index sets. The indexes of 52-tone dRU1 are expanded as follows: {-483,-467,-447,-431,-411,-395,-375,-359,-339,-323,-303,-287,-267,-251,-231,-215,-195,-179,-159,-143,-123,-107,-87,-71,-51,-35,17,33,53,69,89,105,125,141,161,177,197,213,233,249,269,285,305,321,341,357,377,393,413,429,449,465}. As can be seen, the interval between adjacent subcarriers in the positive and negative frequency portions (the interval here refers to the step size when allocating subcarriers) is 16 and 20 subcarriers alternating, for example -483+16=-467, -467+20=-447.

[0341] The numbering pattern of 52-tone dRUs under an 80MHz DBW bandwidth is similar to the previous case, allowing 52-tone dRU1 and 52-tone dRU2 to form the main body of 106-tone dRU1. Starting from the leftmost subcarrier index, a dRU carrier is allocated in a loop: {-483:-468}, with corresponding 52-tone dRU numbers in sequence: {1,9,7,15,3,11,5,13,2,10,8,16,4,12,6,14}. Based on this allocation, 52-tone dRU1 and 52-tone dRU2 form the main body of the approximately uniformly discretely distributed 106-tone dRU1. It should be noted that when all 52-tone dRUs are allocated, the allocated subcarriers (including data and pilots) consist of 32 consecutive subcarriers, spaced 4 subcarriers apart, and then another 32 consecutive subcarriers allocated. For example, a round of subcarrier allocation includes 32 consecutive subcarriers in the range [-483:-452], while the subsequent 4 consecutive subcarriers [-451:-448] are unused empty subcarriers, and so on.

[0342] The 52-tone dRU can be understood as being formed by "interleaving" two virtual 26-tone dRU modes. The 'center' 26-tone dRUs at every 20MHz of bandwidth under the 20MHz and 40MHz DBW do not participate in forming the 52-tone dRU. Therefore, the four 'center' 26-tone dRUs under the simulated 80MHz DBW do not participate in forming the 52-tone dRU, and the next round of four consecutive subcarriers [-415:-412] are unused empty subcarriers. The four virtual 'center' 26-tone dRUs in the negative frequency section on the left... The index set of dRU is {(-451,-450,-449,-448),(-415,-414,-413,-412),(-379,-378,-377,-376),(-343,-342,-341,-340),(-307,-306,-305,-304),(-271,-270,-269,-268), (-235,-234,-233,-232),(-199,-198,-197,-196),(-163,-162,-161,-160),(-127,-126,-125,-124),(-91,-90,-89,-88),(-55,-54,-53,-52),(-19,-18,-17,-16)}. Excluding the remaining unused subcarriers, 32 subcarriers are available near the central DC zero frequency: {-15:-1}∪{0}∪{1:16}. The 29 edge empty subcarriers in the negative frequency region on the left are: [-512:-484], and the 31 edge empty subcarriers in the positive frequency region on the right are: [481:511].

[0343] The 106-tone dRU distribution is similar to a main body composed of 52-tone dRUs supplemented by two edge subcarriers. Note that the edge subcarriers on the left side at negative frequencies have four empty subcarriers: {-487, -486, -485, -484}, thus ensuring the subcarrier spacing of the 106-tone dRU. Similarly, the edge subcarriers on the right side at positive frequencies have four empty subcarriers: {481, 482, 483, 484}.

[0344] The four 242-tone dRUs under the 80MHz DBW bandwidth were redesigned with equally spaced subcarriers for each of the positive and negative frequency bands. When all 242-tone dRUs were allocated, 32 subcarriers were left unused near the central DC zero frequency: {-15:-1}∪{0}∪{1:16}. The 13 edge unused subcarriers in the negative frequency section on the left were [-512:-500], and the 11 edge unused subcarriers in the positive frequency section on the right were [501:511]. Similarly, the two 484-tone dRUs under the 80MHz DBW bandwidth were also redesigned with equally spaced subcarriers for each of the positive and negative frequency bands. When all 484-tone dRUs were allocated, the situation regarding unused subcarriers was the same as when all 242-tone dRUs were allocated, and will not be elaborated here.

[0345] Therefore, if the bandwidth indication is 80 / 160 / 320MHz, and the dRU Distribution BW subfield indicates a distributed bandwidth of 60MHz, the resource subcarrier allocation for the PHY dRU is not yet determined (TBD). Thus, for a distributed bandwidth of 60MHz, there is currently a lack of a 60MHz dRU subcarrier resource planning scheme.

[0346] This disclosure redefines the maximum number of dRUs of various sizes that each DBW can contain, as defined in the standard draft, for the newly added 60MHz distributed bandwidth (DBW). Specifically, the minimum number of dRUs for the 60MHz DBW are 26-tone dRUs and 52-tone dRUs.

[0347] In some embodiments, assuming the usable dRU size for a 60MHz DBW is 26 / 52 / 106 / 242-tone dRU, the dRU subcarrier resource planning for the 60MHz DBW is designed. Since the 60MHz DBW bandwidth is asymmetrical on both sides of the zero frequency, with approximately 40MHz of spectrum resources on the left (negative frequency portion) and approximately 20MHz of spectrum resources on the right (positive frequency portion), the subcarrier allocation in this disclosure is described separately as two large blocks, left and right. The number of empty subcarriers near the central zero frequency can be flexibly changed, and the number of spectrum edge subcarriers on both sides can also be flexibly changed according to the left and right shift of the specific allocated data subcarrier blocks; no specific limitations are imposed here.

[0348] In some embodiments, the resource subcarriers are allocated according to the allocation logic specified in the standard, and in a round-robin manner. When allocating 242-tone dRUs with an 80MHz DBW bandwidth, 32 subcarriers are left empty near the central DC zero frequency: {-15:-1}∪{0}∪{1:16}, the 13 edge empty subcarriers in the negative frequency part on the left are [-512:-500], and the 11 edge empty subcarriers in the positive frequency part on the right are [501:511]. Therefore, the number of zero frequency and spectrum edge subcarriers under the 60MHz DBW bandwidth in this embodiment can refer to the 80MHz DBW case in the standard. Since the highest 20MHz bandwidth is punctured, according to the OFDM subcarrier indexing logic of Wi-Fi, every 27 subcarriers are grouped together, and then allocated in rounds according to the allocation logic of related technologies. For example, if there are a total of 27 26-tone dRUs within the bandwidth, then the total number of resource subcarriers allocated to the 60MHz DBW is 702 = 27 × 26 carriers. The negative and positive frequency portions can be allocated in two ways: Allocation Scheme A allocates 17 rounds to the left negative frequency portion, resulting in 459 = 17 × 27 resource subcarriers, and allocates the remaining 9 rounds to the right positive frequency portion, resulting in 243 = 9 × 27 resource subcarriers; Allocation Scheme B allocates 18 rounds to the left negative frequency portion, resulting in 486 = 18 × 27 resource subcarriers, and allocates the remaining 8 rounds to the right positive frequency portion, resulting in 216 = 8 × 27 resource subcarriers.

[0349] For the above allocation scheme A, as shown in Table 9 below, when allocating 26-tone dRU resource subcarriers, the number of resource subcarriers on the left is 459, assuming that the index of the left resource subcarrier is [-474:-16], and the index of the 243 resource subcarriers on the right is [7:249]. Then the leftmost 27 subcarriers of the first round of the 27 26-tone dRUs are numbered [-474:-448], and their corresponding 26-tone dRU numbers are as follows in Table 9: [1,19,10,6,24,15,|3,21,12,8,26,17,||2,20,11,7,25,16,|4,22,13,9,27,18||5,14,23].

[0350] Based on the above resource subcarrier allocation embodiment A1, the resource subcarrier allocation table (Table 9) and the corresponding dRU numbers for 26-tone dRU and 52-tone dRU under 60MHz DBW are given below.

[0351] Table 9:

[0352] It should be noted that the subcarrier allocation described in this disclosure is divided into two main blocks, left and right. The number of empty subcarriers near the central zero frequency can be flexibly changed, and the number of subcarriers at the spectrum edges on both sides can also be flexibly changed according to the left and right shift of the specific allocated data subcarrier blocks, for example, shifting left or right by x positions (x = 1, 2, 3, ...). For example, all allocated subcarriers in the negative frequency part can be uniformly shifted to the left by 1 position, so that the sequence number of all subcarriers in the negative frequency part table is reduced by 1, but their relative DRU number remains unchanged. For example, 26-tone DRU1 becomes [-475:27:-43,7:27:223]. Similarly, the positive frequency part can also be uniformly shifted left and right, while the positive and negative frequency parts can be shifted independently. The above-mentioned left and right shifting principle also applies to subsequent embodiments.

[0353] In some embodiments, the index of the 26-tone dRU corresponds to the dRU number in Table 10 as follows: [1,10,19,6,15,24,|3,12,21,8,17,26,||2,11,20,7,16,25,|4,13,22,9,18,27||5,14,23].

[0354] Table 10:

[0355] In some embodiments, when allocating 26-tone DRU resource subcarriers, the number of resource subcarriers on the left is 486, assuming that the index of the left resource subcarrier is [-499:-14], and the index of the 216 resource subcarriers on the right is [22:237]. Then the leftmost 27 subcarriers of the first round of 27 26-tone DRUs are numbered [-499:-473], and their corresponding 26-tone DRU numbers are shown in Table 11 below as follows: [1,10,19,6,15,24,|3,12,21,8,17,26,||2,11,20,7,16,25,|4,13,22,9,18,27||5,14,23].

Then the leftmost 27 subcarriers of the first round of 27 26-tone DRUs are numbered [-499:-473], and their corresponding 26-tone DRU numbers are shown in Table 12 below as follows: [1,19,10,6,24,15,|3,21,12,8,26,17,||2,20,11,7,25,16,|4,22,13,9,27,18||5,14,23].

[0360] As shown in Figure 3, the above method can be applied to the first AP 101, and the method includes:
