[0222] In the case that the STA transmits the uplink PPDU using unequal modulation, the maximum number of uplink SSs supported by the STA is 4.

[0225] S22, the AP transmits a second wireless frame, and the second wireless frame includes a second identification field, and the second identification field is used to indicate the first type of dRU allocated by the AP to the STA.

[0226] In some embodiments, after the AP receives the first wireless frame, the AP can transmit a second wireless frame to the STA according to the content indicated by the first wireless frame, so as to indicate the first type of dRU allocated by the AP to the STA through the second identification field in the second wireless frame.

[0227] The second identification field is specifically used to indicate the index information of the first type of dRU, so that the STA determines the first type of dRU allocated by the AP according to the index information indicated by the second identification field.

[0235] In some embodiments, the second wireless frame can be a trigger frame or an NDPA frame.

[0236] When the second wireless frame is a trigger frame, the second identification field can be a userinfo field in the trigger frame; and when the second wireless frame is an NDPA frame, the second identification field can be a STA info field in the NDPA frame.

[0237] When the second identification field is the STA info field or the userinfo field, the second wireless frame further includes an association identifier (AID) field, the AID field being used to indicate a unique association identifier allocated to the STA in an association process between the AP and the STA, and the AID corresponding to the STA info field or the userinfo field, and being used to indicate that the index information of the dRU indicated by the STA info field or the userinfo field is allocated to the STA.

[0238] In some embodiments, the second wireless frame further includes a third identification field, the third identification field being used to indicate at least one of the following:

[0239] a first distribution bandwidth mode adopted by the AP;

[0240] allocating a first type of dRU under a second bandwidth to the STA, the second bandwidth being any one of 20MHz corresponding to the first distribution bandwidth mode.

[0241] Specifically, the first distribution bandwidth mode adopted by the AP includes at least one of the following:

[0242] 80MHz;

[0243] 40MHz+20MHz+20MHz;

[0244] 20MHz + 20MHz + 40MHz.

[0245] In a non-punctured 80MHz PPDU, the dRU transmission allows using the above distributed bandwidth formats.

[0246] As an example, when the first distributed bandwidth format adopted by the AP is 80MHz, the first type of dRU allocated by the AP to the STA is the first type of dRU in any one of the 20MHz bandwidths in the 80MHz.

[0247] As an example, when the first distributed bandwidth format adopted by the AP is 40MHz + 20MHz + 20MHz, the first type of dRU allocated by the AP to the STA is the first type of dRU in any one of the 20MHz bandwidths in the 40MHz + 20MHz + 20MHz.

[0248] As an example, when the first distributed bandwidth format adopted by the AP is 20MHz + 20MHz + 40MHz, the first type of dRU allocated by the AP to the STA is the first type of dRU in any one of the 20MHz bandwidths in the 20MHz + 20MHz + 40MHz.

[0249] In some embodiments, the third identification bit includes the first identification bit, the second identification bit, and the third identification bit.

[0250] In a case where the identification value of the first identification bit is a first value, the third identification domain indicates, through the first identification bit, that the first distributed bandwidth format adopted by the AP is 40MHz + 20MHz + 20MHz; in a case where the identification value of the first identification bit is a second value, the third identification domain indicates, through the first identification bit, that the first distributed bandwidth format adopted by the AP is 20MHz + 20MHz + 40MHz; and in a case where the identification value of the first identification bit is empty (e.g., the first identification bit is a reserved bit), the third identification domain indicates, through the first identification bit, that the first distributed bandwidth format adopted by the AP is 80MHz.

[0251] The first value and the second value are different values, which are not limited herein. For example, the first value and the second value can be 1 and 0 respectively, or 0 and 1 respectively.

[0252] In a case where the identification value of the first identification bit is not empty, i.e., in a case where the identification value of the first identification bit is the first value or the second value, if the identification values of the second identification bit and the third identification bit are the third value and the fourth value respectively, the third identification domain is used to indicate the STA to be allocated the first type of dRU in the first 20MHz corresponding to the first distributed bandwidth format.

[0253] The third value and the fourth value are different values, which are not limited herein. For example, the third value and the fourth value can be 1 and 0 respectively, or 0 and 1 respectively.

[0254] In other words, in a case where the identification value of the first identification bit is the first value, the first distributed bandwidth format is 40MHz+20MHz+20MHz. If the identification values of the second identification bit and the third identification bit are the third value and the fourth value respectively, the third identification domain is used to indicate the STA to be allocated the first type of dRU in the first 20MHz corresponding to 40MHz+20MHz+20MHz; if the identification values of the second identification bit and the third identification bit are the fourth value and the third value respectively, the third identification domain is used to indicate the STA to be allocated the first type of dRU in the second 20MHz corresponding to 40MHz+20MHz+20MHz.

[0255] In a case where the identification value of the first identification bit is the second value, the first distributed bandwidth format is 20MHz+20MHz+40MHz. If the identification value of the second identification bit is the third value and the identification value of the third identification bit is the fourth value, the third identification domain is used to indicate the STA to be allocated the first type of dRU in the first 20MHz corresponding to 20MHz+20MHz+40MHz; if the identification value of the second identification bit is the fourth value and the identification value of the third identification bit is the third value, the third identification domain is used to indicate the STA to be allocated the first type of dRU in the second 20MHz corresponding to 20MHz+20MHz+40MHz.

[0256] Optionally, in a case where the identification value of the first identification bit is empty, the third identification domain can be used to indicate the STA to be allocated the first type of dRU in the first 20MHz of 80MHz through different identification value combinations of the second identification bit and the third identification bit.

[0257] For example, in the case that the identification value of the first identification bit is null, if the identification value of the second identification bit is the fifth value and the identification value of the third identification bit is the sixth value, the third identification domain is used to indicate the STA to be allocated the first type of dRU in the first 20MHz corresponding to 80MHz; if the identification values of the second identification bit and the third identification bit are both the fifth value, the third identification domain is used to indicate the STA to be allocated the first type of dRU in the second 20MHz corresponding to 80MHz; if the identification value of the second identification bit is the sixth value and the identification value of the third identification bit is the fifth value, the third identification domain is used to indicate the STA to be allocated the first type of dRU in the third 20MHz corresponding to 80MHz; if the identification values of the second identification bit and the third identification bit are both the sixth value, the third identification domain is used to indicate the STA to be allocated the first type of dRU in the last 20MHz corresponding to 80MHz.

[0258] wherein, the fifth value and the sixth value are different values, which are not limited herein. For example, the fifth value and the sixth value can be 1 and 0 respectively, or 0 and 1 respectively.

[0259] In some embodiments, the second wireless frame further comprises a fourth identification domain, which is used to indicate the number of spatial streams (SS).

[0260] wherein, when the first wireless frame is used to indicate that the STA supports to transmit the PPDU of the first bandwidth by using the dRU and / or supports to receive the NDP frame of the first bandwidth by using the dRU, the maximum number of SS supported by the STA is 4. At this time, the maximum value of the number of SS indicated by the fourth identification domain is 4.

[0261] wherein, when the first wireless frame is used to indicate that the STA supports to transmit the PPDU of the first bandwidth by using the unequal modulation and / or supports to receive the NDP frame of the first bandwidth by using the unequal modulation, the maximum number of SS supported by the STA can be 4, 8 or 16. At this time, the maximum value of the number of SS indicated by the fourth identification domain is 4, 8 or 16.

[0262] Optionally, the fourth identification domain can be a Number of Columns (Nc) identification bit, or other information domain or identification bit in the second wireless frame, which is not limited herein.

[0263] In some embodiments, when the first identification domain indicates that the STA supports to transmit the PPDU of the first bandwidth by using the MRU or supports to receive the NDP frame of the first bandwidth by using the MRU, the AP can allocate the MRU to the STA by using the second wireless frame, for transmitting the PPDU of the first bandwidth or transmitting the NDP frame of the first bandwidth.

[0264] The MRU allocated by the AP to the STA is the MRU in any one of 20MHz under any one of distributed bandwidth format of 80MHz, 40MHz+20MHz+20MHz, 20MHz+20MHz+40MHz, and the specific allocation manner can be consistent with the allocation manner of the dRU, which will not be repeated here.

[0265] In some embodiments, when the first identification field indicates that the STA supports transmitting a PPDU of the first bandwidth through a RU or supports receiving an NDP frame of the first bandwidth through a RU, the AP can allocate a RU to the STA through a second wireless frame for transmitting the PPDU of the first bandwidth or transmitting the NDP frame of the first bandwidth.

[0266] The RU allocated by the AP to the STA is the RU in any one of 20MHz under any one of distributed bandwidth format of 80MHz, 40MHz+20MHz+20MHz, 20MHz+20MHz+40MHz, and the specific allocation manner can be consistent with the allocation manner of the dRU, which will not be repeated here.

[0267] S23, the STA transmits a PPDU of the first bandwidth through the dRU, and / or the STA receives an NDP frame of the first bandwidth through the dRU, and / or the STA transmits a PPDU of the first bandwidth using unequal modulation, and / or the STA receives an NDP frame of the first bandwidth using unequal modulation.

[0268] In some embodiments, when the STA indicates through the first wireless frame that it supports transmitting a PPDU of the first bandwidth through a dRU, after determining the index information of the first type of dRU allocated by the AP through the second wireless frame (such as a trigger frame), the STA can send or receive the PPDU of the first bandwidth to or from the AP through the dRU corresponding to the index information indicated by the second wireless frame.

[0269] In some embodiments, when the STA indicates through the first wireless frame that it supports receiving an NDP of the first bandwidth through a dRU, after determining the index information of the first type of dRU allocated by the AP through the second wireless frame (such as a trigger frame), the STA can receive the NDP frame of the first bandwidth sent by the AP through the dRU corresponding to the index information indicated by the second wireless frame.
