[0150] FIG2 is one of the interactive diagrams of the resource allocation method according to an embodiment of the present disclosure. The resource allocation method shown in FIG2 includes:

[0151] Step S21: The AP sends a first trigger frame, where the first trigger frame includes at least one user information field, and each user information field is used to allocate an uplink dRU to a STA.

[0152] In some embodiments, the AP may determine and send a first trigger frame (TF) to at least one STA to allocate an uplink DRU for uplink data transmission to the at least one STA.

[0153] The first trigger frame includes a user information list (User Info List) field, the user information list field includes at least one user information (User Info) field, each user information field corresponds to a STA and is used to allocate an uplink dRU to the STA.

[0154] In some embodiments, each user information field includes a dRU allocation subfield, and the dRU allocation subfield included in each user information field is used to allocate an uplink dRU to a corresponding STA.

[0155] The dRU allocation subfield in each user information field may indicate the uplink dRU allocated to the corresponding STA through at least one bit.

[0156] For example, the dRU allocation subfield in each user information field may indicate the uplink dRU allocated to the corresponding STA through 7 bits.

[0157] The uplink dRUs allocated by the AP to each STA through the first trigger frame correspond to different dRU index values, that is, the uplink dRUs allocated by the AP to each STA are different from each other.

[0158] In some embodiments, the format of the uplink DRU allocated by the AP to each STA may be at least one of the following:

[0159] 26-tone-dRU;

[0160] 52-tone-dRU;

[0161] 106-tone-dRU;

[0162] 242-tone-dRU;

[0163] 484-tone-dRU;

[0164] 26-tone-dRU+52-tone-dRU;

[0165] 26-tone-dRU+106-tone-dRU;

[0166] 52-tone-dRU+106-tone-dRU.

[0167] Among them, 26-tone-dRU+52-tone-dRU, 26-tone-dRU+106-tone-dRU and 52-tone-dRU+106-tone-dRU are multiple distributed resource units (multiple dRU, M-dRU).

[0168] Among them, 52-tone-dRU=26-tone-dRU+26-tone-dRU.

[0169] Among them, 106-tone-dRU=52-tone-dRU+52-tone-dRU+2null tones.

[0170] Among them, 242-tone-dRU=106-tone-dRU+106-tone-dRU+26-tone-dRU+4null tones.

[0171] Among them, 484-tone-dRU=242-tone-dRU+242-tone-dRU.

[0172] In some embodiments, the uplink DRU allocated by the AP to each STA is related to the working bandwidth of the STA, and the working bandwidth of the STA includes 20 MHz, 40 MHz, 80 MHz, 160 MHz or 320 MHz.

[0173] The working bandwidth of the STA can be understood as the channel bandwidth or working bandwidth for the STA to perform uplink data transmission.

[0174] Each working bandwidth may correspond to at least one dRU format. When the AP allocates an uplink dRU to each STA, it may allocate the uplink dRU using one or more dRU formats corresponding to the working bandwidth of the STA.

[0175] For example, when the STA's operating bandwidth is 20 MHz, the AP can allocate uplink dRUs to the STA using one or more combinations of dRU formats such as 26-tone-dRU, 52-tone-dRU, and 106-tone-dRU, or can allocate uplink dRUs to the STA using the M-dRU format of 26-tone-dRU + 52-tone-dRU.

[0176] For example, when the STA's operating bandwidth is 40 MHz, the AP can allocate uplink DRUs to the STA using one or more combinations of DRU formats such as 26-tone-dRU, 52-tone-dRU, 106-tone-dRU, and 242-tone-dRU, or can allocate uplink DRUs to the STA using the M-dRU format of 26-tone-dRU + 52-tone-dRU, 26-tone-dRU + 106-tone-dRU, or 52-tone-dRU + 106-tone-dRU.

[0177] For example, when the STA's operating bandwidth is 80 MHz, the AP can use one or more combinations of dRU formats such as 26-tone-dRU, 52-tone-dRU, 106-tone-dRU, 242-tone-dRU, and 484-tone-dRU to allocate uplink dRUs to the STA, or can use any of the above M-dRU formats to allocate uplink dRUs to the STA.

[0178] For example, when the STA's operating bandwidth is 160 MHz, the AP can use one or more combinations of dRU formats such as 26-tone-dRU, 52-tone-dRU, 106-tone-dRU, 242-tone-dRU, 484-tone-dRU to allocate uplink dRUs to the STA, or can use any of the above M-dRU formats to allocate uplink dRUs to the STA.

[0179] In some embodiments, each user information field also includes an uplink modulation and coding strategy (UL MCS) subfield, which is used to indicate the modulation and coding measurements sampled when the corresponding STA performs uplink data transmission, that is, to indicate the modulation and coding strategy adopted by the corresponding STA to send an uplink physical layer protocol data unit (Physical Layer Protocol Data Unit, PPDU).

[0180] In some embodiments, each user information field also includes a spatial stream allocation (SS allocation) subfield, which is used to indicate the spatial stream (SS) information of the corresponding STA when performing uplink data transmission, that is, to indicate the spatial stream information when the corresponding STA sends an uplink PPDU.

[0181] The spatial stream information includes the starting spatial stream and the number of spatial streams.

[0182] In some embodiments, each user information field also includes an uplink target receive power (UL target receive power) subfield, which is used to indicate the transmit power value of the corresponding STA when performing uplink data transmission, that is, to indicate the transmit power value of the uplink PPDU that the AP expects to receive.

[0183] In some embodiments, each user information field further includes an Association Identifier (AID) subfield, where the Association Identifier field is used to indicate the AID allocated by the AP to the corresponding STA.

[0184] Since each STA corresponds to a different AID, each user information field can distinguish different STAs by associating the AID indicated by the identifier field.

[0185] For example, when each user information field includes a dRU allocation subfield, the dRU allocation subfield in each user information field corresponds to the association identifier subfield. That is, each user information field indicates through the association identifier field that the dRU allocation subfield in the user information field is used to allocate an uplink dRU to the STA corresponding to the AID indicated by the association identifier in the user information field.

[0186] In some embodiments, the first trigger frame includes a common information field, the common information field includes a trigger type subfield, and the trigger type subfield indicates through a first value that the first trigger frame is used to allocate an uplink dRU to at least one STA.

[0187] As an example, the trigger type subfield may indicate the type (or function) of the first trigger frame through different identification values, as shown in the following table:

[0188] As shown in the above table, the first value of the trigger type subfield can be any value from 9 to 15, to indicate that an uplink DRU is allocated to at least one STA.

[0189] In some embodiments, the first trigger frame includes a common information field, the common information field includes an uplink bandwidth (UL BW) subfield, and the uplink bandwidth subfield is used to indicate the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA.

[0190] Among them, the uplink bandwidth subdomain may include a first identifier and a second identifier. When the identification values ​​of the first identifier and the second identifier are both the third value, the uplink bandwidth subdomain is used to indicate that the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA is 20 MHz; when the identification value of the first identifier is the third value and the identification value of the second identifier is the fourth value, the uplink bandwidth subdomain is used to indicate that the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA is 40 MHz; when the identification value of the first identifier is the fourth value and the identification value of the second identifier is the third value, the uplink bandwidth subdomain is used to indicate that the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA is 80 MHz; when the identification values ​​of the first identifier and the second identifier are both the fourth value, the uplink bandwidth subdomain is used to indicate that the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA is 160 MHz.

[0191] The third value may be 0, and the fourth value may be 1.

[0192] Among them, the uplink bandwidth subdomain may include a first identification bit, a second identification bit and a third identification bit. The first identification bit, the second identification bit and the third identification bit indicate through a specific identification value combination that the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA is 320MHz.

[0193] For example, a specific identification value combination can be that the identification value of the first identification bit is the third value, the identification value of the second identification bit is the fourth value, and the identification value of the third identification bit is the fourth value, which is not limited in this disclosure.

[0194] In some embodiments, the first trigger frame includes a common information field, the common information field includes a more trigger frame (more TF) subfield, and the more trigger frame subfield indicates through a second value that the AP sends at least one second trigger frame after sending the first trigger frame within a transmission opportunity TXOP.

[0195] Each second trigger frame is used to allocate an uplink DRU to at least one STA.

[0196] That is, after the AP sends the first trigger frame, if the identification value of the more trigger frame subfield in the first trigger frame is the second value, it means that the AP will send at least one second trigger frame after sending the first trigger frame to allocate uplink dRU to multiple STAs through the first trigger frame and the second trigger frame.

[0197] In some embodiments, the first trigger frame includes a common information field, the common information field includes an uplink spatial reuse (UL spatial reuse) subfield, and the uplink spatial reuse subfield is used to indicate that at least one STA is allowed to perform uplink data transmission at the same time, that is, to indicate that each STA sends an uplink PPDU at the same time.

[0198] In some embodiments, the first trigger frame includes a common information field, the common information field includes an uplink length (UL Length) subfield, and the uplink length subfield is used to indicate the length of the uplink trigger-based (TB) PPDU sent by the STA.

[0199] In some embodiments, the first trigger frame includes a common information field, the common information field includes a long training field number (number of LTF) subfield, and the long training field number subfield is used to indicate the number of long training fields of the uplink PPDU sent by the STA.

[0200] The number of long training fields is related to the number of user information fields in the first trigger frame, which in turn is related to the number of STAs to which uplink DRUs are allocated. For example, if multiple STAs are communicating with the AP simultaneously, each using a different spatial stream, the number of LTFs must match the number of STAs and spatial streams. Specifically, if there are N STAs, each using M spatial streams, the number of LTFs required is N*M.

[0201] As an example, the format of the first trigger frame may be as follows:

[0202] The User Info List field in the first trigger frame includes at least one User Info field. The format of each User Info field can be as follows:

[0203] Among them, each User Info field includes a dRU Allocation subfield and an AID subfield. The dRU Allocation subfield is used to allocate an uplink dRU to the STA associated with the AID indicated by the AID subfield. Each User Info field also includes a UL MCS subfield, an SS allocation subfield, and a UL Target Receive Power subfield. The UL MCS subfield is used to indicate the MCS used when the STA associated with the AID indicated by the AID subfield sends a UL PPDU. The SS allocation subfield is used to indicate the spatial stream information when the STA associated with the AID indicated by the AID subfield sends an uplink PPDU. The UL Target Receive Power subfield is used to indicate the transmit power value of the uplink PPDU sent by the STA associated with the AID indicated by the AID subfield.

[0204] The format of the Common Info field in the first trigger frame may be as follows:

[0205] Among them, the Trigger Type subfield in the Common Info domain indicates through the first value that the first trigger frame is used to allocate uplink dRU, the UL BW subfield is used to indicate the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA, the More TF subfield indicates through the second value that the AP sends at least one second trigger frame for allocating uplink dRU after sending the first trigger frame, the UL Spatial Reuse subfield is used to indicate that the AP allows at least one STA to perform uplink data transmission simultaneously, the UL Length subfield is used to indicate the length of the UL TB PPDU, and the Number of LTF subfield is used to indicate the number of long training fields of the UL TB PPDU.

[0206] The User Info and Common Info fields may also include other information subfields, which are not described in this embodiment. Furthermore, the positional relationship and number of bits occupied by each information subfield in the User Info and Common Info fields are not limited in this embodiment.

[0207] Step S22: The first STA performs uplink data transmission according to the uplink dRU allocated by the AP.

[0208] In some embodiments, after receiving the first trigger frame, the first STA may determine the uplink DRU allocated to it by the AP, and then send an uplink PPDU to the AP according to the uplink DRU allocated by the AP.

[0209] The resource allocation method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, any one of steps S21 and S22 may be implemented as an independent embodiment, and steps S21 and S22 may be implemented as independent embodiments, but are not limited thereto.

[0210] FIG3 is a flow chart of a resource allocation method according to an embodiment of the present disclosure. As shown in FIG3 , the method is executed by an AP and includes:

[0211] Step S31: Determine a first trigger frame, where the first trigger frame includes at least one user information field, and each user information field is used to allocate an uplink distributed resource unit dRU to a STA.

[0212] In some embodiments, the AP may determine a first trigger frame (TF) to allocate an uplink DRU for uplink data transmission to at least one STA through the first trigger frame.

[0213] The first trigger frame includes a user information list (User Info List) field, the user information list field includes at least one user information (User Info) field, each user information field corresponds to a STA and is used to allocate an uplink dRU to the STA.

[0214] In some embodiments, each user information field includes a dRU allocation subfield, and the dRU allocation subfield included in each user information field is used to allocate an uplink dRU to a corresponding STA.

[0215] The dRU allocation subfield in each user information field may indicate the uplink dRU allocated to the corresponding STA through at least one bit.

[0216] For example, the dRU allocation subfield in each user information field may indicate the uplink dRU allocated to the corresponding STA through 7 bits.

[0217] The uplink dRUs allocated by the AP to each STA through the first trigger frame correspond to different dRU index values, that is, the uplink dRUs allocated by the AP to each STA are different from each other.

[0218] In some embodiments, the format of the uplink DRU allocated by the AP to each STA may be at least one of the following:

[0219] 26-tone-dRU;

[0220] 52-tone-dRU;

[0221] 106-tone-dRU;

[0222] 242-tone-dRU;

[0223] 484-tone-dRU;

[0224] 26-tone-dRU+52-tone-dRU;

[0225] 26-tone-dRU+106-tone-dRU;

[0226] 52-tone-dRU+106-tone-dRU.

[0227] Among them, 26-tone-dRU+52-tone-dRU, 26-tone-dRU+106-tone-dRU and 52-tone-dRU+106-tone-dRU are multiple distributed resource units (multiple dRU, M-dRU).

[0228] Among them, 52-tone-dRU=26-tone-dRU+26-tone-dRU.

[0229] Among them, 106-tone-dRU=52-tone-dRU+52-tone-dRU+2null tones.

[0230] Among them, 242-tone-dRU=106-tone-dRU+106-tone-dRU+26-tone-dRU+4null tones.

[0231] Among them, 484-tone-dRU=242-tone-dRU+242-tone-dRU.

[0232] In some embodiments, the uplink DRU allocated by the AP to each STA is related to the working bandwidth of the STA, and the working bandwidth of the STA includes 20 MHz, 40 MHz, 80 MHz, 160 MHz or 320 MHz.

[0233] The working bandwidth of the STA can be understood as the channel bandwidth or working bandwidth for the STA to perform uplink data transmission.

[0234] Each working bandwidth may correspond to at least one dRU format. When the AP allocates an uplink dRU to each STA, it may allocate the uplink dRU using one or more dRU formats corresponding to the working bandwidth of the STA.

[0235] For example, when the STA's operating bandwidth is 20 MHz, the AP can allocate uplink dRUs to the STA using one or more combinations of dRU formats such as 26-tone-dRU, 52-tone-dRU, and 106-tone-dRU, or can allocate uplink dRUs to the STA using the M-dRU format of 26-tone-dRU + 52-tone-dRU.

[0236] For example, when the STA's operating bandwidth is 40 MHz, the AP can allocate uplink DRUs to the STA using one or more combinations of DRU formats such as 26-tone-dRU, 52-tone-dRU, 106-tone-dRU, and 242-tone-dRU, or can allocate uplink DRUs to the STA using the M-dRU format of 26-tone-dRU + 52-tone-dRU, 26-tone-dRU + 106-tone-dRU, or 52-tone-dRU + 106-tone-dRU.

[0237] For example, when the STA's operating bandwidth is 80 MHz, the AP can use one or more combinations of dRU formats such as 26-tone-dRU, 52-tone-dRU, 106-tone-dRU, 242-tone-dRU, and 484-tone-dRU to allocate uplink dRUs to the STA, or can use any of the above M-dRU formats to allocate uplink dRUs to the STA.

[0238] For example, when the STA's operating bandwidth is 160 MHz, the AP can use one or more combinations of dRU formats such as 26-tone-dRU, 52-tone-dRU, 106-tone-dRU, 242-tone-dRU, 484-tone-dRU to allocate uplink dRUs to the STA, or can use any of the above M-dRU formats to allocate uplink dRUs to the STA.

[0239] In some embodiments, each user information field also includes an uplink modulation and coding strategy (UL MCS) subfield, which is used to indicate the modulation and coding measurements sampled when the corresponding STA performs uplink data transmission, that is, to indicate the modulation and coding strategy adopted by the corresponding STA to send an uplink physical layer protocol data unit (Physical Layer Protocol Data Unit, PPDU).

[0240] In some embodiments, each user information field also includes a spatial stream allocation (SS allocation) subfield, which is used to indicate the spatial stream information when the corresponding STA performs uplink data transmission, that is, to indicate the spatial stream information when the corresponding STA sends an uplink PPDU.

[0241] The spatial stream information includes the starting spatial stream and the number of spatial streams.

[0242] In some embodiments, each user information field also includes an uplink target receive power (UL target receive power) subfield, which is used to indicate the transmit power value of the corresponding STA when performing uplink data transmission, that is, to indicate the transmit power value of the uplink PPDU that the AP expects to receive.

[0243] In some embodiments, each user information field further includes an Association Identifier (AID) subfield, where the Association Identifier field is used to indicate the AID allocated by the AP to the corresponding STA.

[0244] Since each STA corresponds to a different AID, each user information field can distinguish different STAs by associating the AID indicated by the identifier field.

[0245] For example, when each user information field includes a dRU allocation subfield, the dRU allocation subfield in each user information field corresponds to the association identifier subfield. That is, each user information field indicates through the association identifier field that the dRU allocation subfield in the user information field is used to allocate an uplink dRU to the STA corresponding to the AID indicated by the association identifier in the user information field.

[0246] In some embodiments, the first trigger frame includes a common information field, the common information field includes a trigger type subfield, and the trigger type subfield indicates through a first value that the first trigger frame is used to allocate an uplink dRU to at least one STA.

[0247] As an example, the trigger type subfield may indicate the type (or function) of the first trigger frame through different identification values, as shown in the following table:

[0248] As shown in the above table, the first value of the trigger type subfield can be any value from 9 to 15, to indicate that an uplink DRU is allocated to at least one STA.

[0249] In some embodiments, the first trigger frame includes a common information field, the common information field includes an uplink bandwidth (UL BW) subfield, and the uplink bandwidth subfield is used to indicate the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA.

[0250] Among them, the uplink bandwidth subdomain may include a first identifier and a second identifier. When the identification values ​​of the first identifier and the second identifier are both the third value, the uplink bandwidth subdomain is used to indicate that the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA is 20 MHz; when the identification value of the first identifier is the third value and the identification value of the second identifier is the fourth value, the uplink bandwidth subdomain is used to indicate that the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA is 40 MHz; when the identification value of the first identifier is the fourth value and the identification value of the second identifier is the third value, the uplink bandwidth subdomain is used to indicate that the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA is 80 MHz; when the identification values ​​of the first identifier and the second identifier are both the fourth value, the uplink bandwidth subdomain is used to indicate that the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA is 160 MHz.

[0251] The third value may be 0, and the fourth value may be 1.

[0252] Among them, the uplink bandwidth subdomain may include a first identification bit, a second identification bit and a third identification bit. The first identification bit, the second identification bit and the third identification bit indicate through a specific identification value combination that the maximum channel bandwidth corresponding to the uplink dRU allocated to each STA is 320MHz.

[0253] For example, a specific identification value combination can be that the identification value of the first identification bit is the third value, the identification value of the second identification bit is the fourth value, and the identification value of the third identification bit is the fourth value, which is not limited in this disclosure.

[0254] In some embodiments, the first trigger frame includes a common information field, the common information field includes a more trigger frame (more TF) subfield, and the more trigger frame subfield indicates through a second value that the AP sends at least one second trigger frame after sending the first trigger frame within a transmission opportunity TXOP.

[0255] Each second trigger frame is used to allocate an uplink DRU to at least one STA.

[0256] In some embodiments, the first trigger frame includes a common information field, the common information field includes an uplink spatial reuse (UL spatial reuse) subfield, and the uplink spatial reuse subfield is used to indicate that at least one STA is allowed to perform uplink data transmission at the same time, that is, to indicate that each STA sends an uplink PPDU at the same time.

[0257] In some embodiments, the first trigger frame includes a common information field, the common information field includes an uplink length (UL Length) subfield, and the uplink length subfield is used to indicate the length of the uplink trigger-based (TB) PPDU sent by the STA.

[0258] In some embodiments, the first trigger frame includes a common information field, the common information field includes a long training field number (number of LTF) subfield, and the long training field number subfield is used to indicate the number of long training fields of the uplink PPDU sent by the STA.

[0259] The number of long training fields is related to the number of user information fields in the first trigger frame, which in turn is related to the number of STAs to which uplink DRUs are allocated. For example, if multiple STAs are communicating with the AP simultaneously, each using a different spatial stream, the number of LTFs must match the number of STAs and spatial streams. Specifically, if there are N STAs, each using M spatial streams, the number of LTFs required is N*M.

[0260] Step S32: Send a first trigger frame.

[0261] In some embodiments, after determining the first trigger frame, the AP may send the first trigger frame to at least one STA to allocate an uplink dRU to each STA.

[0262] After that, the AP can receive the uplink PPDU sent by each STA according to the uplink DRU allocated to each STA.

[0263] The resource allocation method involved in the embodiments of the present disclosure may include at least one of the aforementioned steps and embodiments. For example, any one of steps S31 and S32 may be implemented as an independent embodiment, and steps S31 and S32 may be implemented as independent embodiments, but are not limited thereto.

[0264] FIG4 is a second flow chart illustrating a resource allocation method according to an embodiment of the present disclosure. As shown in FIG5 , the method is executed by a first STA, and the method includes:

[0265] Step S41: Receive a first trigger frame, where the first trigger frame includes at least one user information field, and each user information field is used to allocate an uplink distributed resource unit dRU to a STA.

[0266] In some embodiments, the relevant description of the first trigger frame can be found in the description of the first trigger frame in FIG. 2 and / or FIG. 3 , which will not be repeated here.

[0267] In some embodiments, the first STA is any STA to which the AP allocates an uplink DRU. After receiving the first trigger frame, the first STA may determine the uplink DRU allocated by the AP to the first STA, and then send an uplink PPDU to the AP according to the uplink DRU allocated by the AP.
