[0045] It should be understood that the terms "system" and "network" are often used interchangeably herein. The term "and / or" is simply a description of an association between related objects, indicating that three possible relationships exist. For example, "A and / or B" can represent: A exists alone, A and B exist simultaneously, or B exists alone. Furthermore, the character " / " generally indicates that the related objects are in an "or" relationship.

The following relevant technologies can be arbitrarily combined with the technical solutions of the embodiments of the present application as optional solutions, and they all fall within the protection scope of the embodiments of the present application.
[0049] Allocation and use of RU (Resource Unit) and MRU
[0050] The current maximum bandwidth of a Wi-Fi channel is 320 MHz. Eight types of RUs (Resource Units) are defined, along with an MRU, which consists of multiple RUs. A RU or MRU can be assigned to a STA as follows.
[0051] (1)RU
[0052] Examples of RUs used for uplink and downlink OFDMA (Orthogonal Frequency Division Multiple Access) transmission in EHT (Extremely High Throughput) PPDUs are as follows: 26-tone RU, 52-tone RU, 106-tone RU, 242-tone RU, 484-tone RU, 996-tone RU, and 2×996-tone RU (two 996-tone RUs). "Tone" indicates the number of subcarriers, for example, 26-tone indicates 26 subcarriers. RUs are categorized into large-size RUs and small-size RUs:
[0053] Large RU: RU size is greater than or equal to 242-tone, including 242-tone RU, 484-tone RU, 996-tone RU, and 2 × 996-tone RU.
[0054] Small RU: RU size is smaller than 242-tone, including 26-tone RU, 52-tone RU, and 106-tone RU.

[0056] (2)MRU
[0057] A small RU can only be combined with another small RU to form a small MRU. A large RU can only be combined with another large RU to form a large MRU.
[0058] (a) Small size MRU
[0059] Examples of small MRUs for uplink and downlink OFDMA transmission using EHT PPDUs are as follows: a 52+26-tone MRU and a 106+26-tone MRU (a combination of a 106-tone and a 26-tone MRU). The 52-tone RU and 26-tone RU in any 52+26-tone MRU must be from the same 20 MHz subchannel. The 106-tone RU and 26-tone RU in any 106+26-tone MRU must be from the same 20 MHz subchannel.
[0060] (b) Large size MRU
[0061] Examples of large MRU sizes for EHT PPDU uplink and downlink OFDMA transmission are as follows: 484+242-tone MRU, 996+484-tone MRU, 2×996+484-tone MRU, 3×996-tone MRU, and 3×996+484-tone MRU.
[0062] The 484+242-tone MRU is allowed to be used in 80 MHz, 160 MHz, and 320 MHz OFDMA EHT PPDUs. The 484-tone RU and 242-tone RU in any 484+242-tone MRU must come from the same 80 MHz subchannel.
[0063] The 996+484-tone MRU is allowed to be used in 160MHz and 320MHz OFDMA EHT PPDUs. The 996-tone RU and 484-tone RU in any 996+484-tone MRU must come from the same 160MHz subchannel.
[0064] 2×996+484-tone MRU, 3×996-tone MRU, and 3×996+484-tone MRU are allowed to be used in 320MHz OFDMA EHT PPDU. The 996-tone RU and 484-tone RU in any 2×996+484-tone MRU must come from three consecutive 80MHz subchannels.
[0065] FIG2 is a schematic flow chart of a communication method 200 according to an embodiment of the present application. The method can optionally be applied to the system shown in FIG1 , but is not limited thereto. The method includes at least part of the following contents.
[0066] S210: The station obtains transmission resources for a data packet, where the transmission resources for the data packet include an MRU divided based on a first channel.
[0067] In this embodiment of the present application, a station can be an AP STA or a non-AP STA. The transmission resource for a data packet can include a first channel. The first channel can be divided to obtain an MRU. The station can divide the first channel to obtain the MRU itself, or obtain information about the MRU of the divided first channel from another device. The station can use the transmission resource for the data packet to send and / or receive data packets.
[0068] In one implementation, the MRU is obtained by dividing the first channel based on the bandwidth and / or puncturing information of the first channel.
[0069] In the embodiment of the present application, multiple MRUs may be divided according to the bandwidth of the first channel, and then puncture holes in the multiple MRUs based on the puncture information to obtain a final MRU.
[0070] In one embodiment, the puncturing information includes at least one of a puncturing granularity, a location of a punctured subchannel, and a number of punctured subchannels.
[0071] In this embodiment of the present application, the puncturing granularity may include the bandwidth of the punctured subchannel. For example, the puncturing granularity may be a 20 MHz subchannel, a 40 MHz subchannel, an 80 MHz subchannel, and so on. The location of the punctured subchannel may include the specific location of the puncture within the frequency range of the first channel's bandwidth. The number of punctured subchannels may be one or more.
[0072] In one embodiment, the data packet is an ultra-high-reliability (UHR) PPDU (Physical Layer Protocol Data Unit).
[0073] In one embodiment, the UHR PPDU may include a UHR MU (Multiple User) PPDU and / or a UHR TB (Trigger based) PPDU.
[0074] For example, a UHR MU PPDU can be used for transmission to one or more users. The UHR MU PPDU may include at least one of the following fields: L-STF (Non-HT Short Training Field), L-LTF (Non-HT Long Training Field), L-SIG (Non-HT SIGNAL Field), U-SIG (Universal SIGNAL Field), UHR-SIG (UHR SIGNAL Field), UHR-STF (UHR Short Training Field), UHR-LTF (UHR Long Training Field), Data, and PE (Packet Extension Field). L-STF, L-LTF, L-SIG, U-SIG, and UHR-SIG are referred to as pre-UHR (pre-UHR or forward UHR) modulation fields, while UHR-STF, UHR-LTF, Data, and PE are referred to as UHR modulation fields.
[0075] For example, a UHR TB PPDU can be used to transmit a response trigger frame from an AP. A UHR TB PPDU can include the L-STF, L-LTF, L-SIG, U-SIG, UHR-STF, UHR-LTF, Data, and PE fields. The L-STF, L-LTF, L-SIG, and U-SIG are called pre-UHR modulation fields, while the UHR-STF, UHR-LTF, Data, and PE fields are called UHR modulation fields.
[0076] In one embodiment, the UHR Modulation field of the UHR PPDU may use MRU.
[0077] In one embodiment, the bandwidth of the first channel is greater than a set bandwidth, and the size of the MRU is greater than a set size.
[0078] In embodiments of the present application, the set bandwidth may be the maximum channel bandwidth or a larger channel bandwidth of the communication system. For example, the maximum bandwidth of the 5 GHz band is 160 MHz. The maximum bandwidth of the 6 GHz band is 320 MHz. The first channel may be a newly added channel, and the bandwidth of the first channel may be the newly added bandwidth. The transmission resources of the communication system may be divided to obtain a first channel with a large bandwidth. For example, in UHR (Ultra-High Reliability) Wi-Fi communication, the bandwidth of the first channel may include the newly added bandwidth, which may be 240 MHz, 480 MHz, or 640 MHz in the 5 GHz band, or 240 MHz, 480 MHz, or 640 MHz in the 6 GHz band. The specific value of the newly added channel bandwidth in the above examples may also be other values. The size of the MRU may be larger than the set size. For example, the set size may be 242-tone, 484-tone, or 996-tone. If it is necessary to puncture one subchannel in the first channel, puncturing may be performed in order of frequency from low to high or from high to low, resulting in multiple MRUs. If multiple sub-channels need to be punctured in the first channel, one sub-channel may be punctured first, and then another sub-channel may be punctured in the remaining bandwidth until the puncturing is completed.
[0079] In one embodiment, the first channel is a 240 MHz channel, which is a channel with a bandwidth of 240 MHz in a 5 GHz frequency band, or a channel with a bandwidth of 240 MHz in a 6 GHz frequency band.
[0080] In an embodiment of the present application, the bandwidth of a 240MHz channel can be divided and punctured to obtain an MRU of the 240MHz channel. For example, an MRU is constructed based on the 240MHz bandwidth, and the puncturing granularity of the 240MHz channel is 20MHz. A 2×996+484+242-tone MRU is formed by puncturing one 20MHz sub-channel, and the MRU includes two 996-tone RUs, one 484-tone RU, and one 242-tone RU. A 2×996+484-tone MRU is formed by puncturing one 40MHz sub-channel, and the MRU includes two 996-tone RUs and one 484-tone RU.
[0081] In one embodiment, the MRU is used for transmission of a PPDU with a bandwidth of 240 MHz, where the PPDU with a bandwidth of 240 MHz includes a non-OFDMA 240 MHz UHR PPDU and / or an OFDMA 240 MHz UHR PPDU.
[0082] In one embodiment, the puncturing information is to puncture one 20MHz subchannel, and the puncturing method of the 240MHz channel includes: in the bandwidth of the 240MHz channel, puncturing the 1st to 12th 20MHz subchannels respectively in frequency order to obtain 12 types of MRUs, and the MRU includes 2 RUs of 996 subcarriers, one RU of 484 subcarriers and one RU of 242 subcarriers.
[0083] An example of a 2×996+484+242-tone MRU for uplink or downlink PPDU transmission is as follows: A 2×996+484+242-tone MRU allows for puncturing of one 20 MHz subchannel within a 240 MHz UHR PPDU. The 2×996+484+242-tone MRU consists of two 996-tone RUs, one 484-tone RU, and one 242-tone RU within a 240 MHz UHR PPDU. Within the 240 MHz bandwidth, 20 MHz subchannels 1 through 12 are punctured in ascending order (or descending order), forming 2×996+484+242-tone MRUs 1 through 12.
[0084] In one case, the 2×996+484+242-tone MRU is used only for non-OFDMA (Orthogonal frequency division multiple access) 240MHz UHR PPDU transmission.
[0085] In another case, a 2×996+484+242-tone MRU can be used for non-OFDMA 240 MHz UHR PPDU transmission and OFDMA 240 MHz UHR PPDU transmission.
[0086] In one embodiment, the data subcarriers of the MRU are composed of the union of the data subcarriers of two 996-subcarrier RUs, one 484-subcarrier RU, and one 242-subcarrier RU that constitute the MRU; and / or, the pilot subcarriers of the MRU are composed of the union of the pilot subcarriers of two 996-subcarrier RUs, one 484-subcarrier RU, and one 242-subcarrier RU that constitute the MRU.
[0087] For example, the data subcarriers of a 2×996+484+242-tone MRU consist of the union of two 996-tone RUs, one 484-tone RU, and one 242-tone RU. For another example, the pilot subcarriers of a 2×996+484+242-tone MRU consist of the union of two 996-tone RUs, one 484-tone RU, and one 242-tone RU.
[0088] In one embodiment, the puncturing information is to puncture one 40MHz subchannel, and the puncturing method of the 240MHz channel includes: in the bandwidth of the 240MHz channel, puncturing the first to sixth 40MHz subchannels respectively in frequency order to obtain 6 types of MRUs, and the MRU includes 2 RUs of 996 subcarriers and one RU of 484 subcarriers.
[0089] An example of a 2×996+484-tone MRU for uplink or downlink PPDU transmission is as follows: A 2×996+484-tone MRU allows for puncturing one 40 MHz subchannel within a 240 MHz UHR PPDU. The 2×996+484-tone MRU consists of two 996-tone RUs and one 484-tone RU within a 240 MHz UHR PPDU. Within the 240 MHz bandwidth, 40 MHz subchannels 1 through 6 are punctured in ascending order (or descending order) to form 2×996+484-tone MRUs 1 through 6.
[0090] In one case, the 2×996+484-tone MRU is used only for non-OFDMA 240MHz UHR PPDU transmission.
[0091] In another case, a 2×996+484-tone MRU can be used for non-OFDMA 240MHz UHR PPDU transmission and OFDMA 240MHz UHR PPDU transmission.
[0092] In one embodiment, the data subcarriers of the MRU are composed of the union of the data subcarriers of the two RUs of 996 subcarriers and the one RU of 484 subcarriers constituting the MRU; and / or, the pilot subcarriers of the MRU are composed of the union of the pilot subcarriers of the two RUs of 996 subcarriers and the one RU of 484 subcarriers constituting the MRU.
[0093] For example, the data subcarriers of a 2×996+484-tone MRU consist of the union of two 996-tone RUs and one 484-tone RU. For another example, the pilot subcarriers of a 2×996+484+242-tone MRU consist of the union of two 996-tone RUs and one 484-tone RU.
[0094] In one embodiment, the first channel is a 480 MHz channel, which is a channel with a bandwidth of 480 MHz in a 5 GHz frequency band, or a channel with a bandwidth of 480 MHz in a 6 GHz frequency band.
[0095] In an embodiment of the present application, the bandwidth of a 480MHz channel can be divided and punctured to obtain an MRU of the 480MHz channel. For example, an MRU is constructed based on a 480MHz bandwidth, and the puncturing granularity of the 480MHz channel is 40MHz. A 5×996+484-tone MRU is formed by puncturing one 40MHz sub-channel. A 5×996-tone MRU is formed by puncturing one 80MHz sub-channel, and the MRU includes five 996-tone RUs. A 4×996+484-tone MRU is formed by simultaneously puncturing one 80MHz sub-channel and one 40MHz sub-channel, and the MRU includes four 996-tone RUs and one 484-tone RU.
[0096] In one embodiment, the MRU is used for transmission of a PPDU with a bandwidth of 480 MHz, where the PPDU with a bandwidth of 480 MHz includes a non-OFDMA 480 MHz UHR PPDU and / or an OFDMA 480 MHz UHR PPDU.

Within the 480 MHz bandwidth, 40 MHz subchannels 1 through 12 are punctured in ascending order (or descending order), forming 5×996+484-tone MRUs 1 through 12.

[0250] (1)UHR MU PPDU
[0251] The format of the UHR MU PPDU is shown in Figure 4 and is used for transmission to one or more users. The L-STF field is primarily used for signal detection, automatic gain control, time synchronization, and coarse frequency offset estimation; the L-LTF field is primarily used for channel estimation and further frequency offset estimation; the L-SIG field conveys rate and length information; the RL-SIG is a repetition of the L-SIG; the U-SIG and UHR-SIG fields carry information for decoding the PPDU; the UHR-STF field is used to improve automatic gain control estimation in MIMO transmission; the UHR-LTF is used for MIMO channel estimation from the constellation mapping output to the receiving link; the Data field transmits information; and the PE field is a packet extension. In the UHR MU PPDU, the L-STF, L-LTF, L-SIG, U-SIG, and UHR-SIG are referred to as the pre-UHR modulation field; the UHR-STF, UHR-LTF, Data, and PE are referred to as the UHR modulation field.
[0252] (2)UHR TB PPDU
[0253] Figure 5 shows the format of the UHR TB PPDU, which is used to transmit a response trigger frame from an AP. In a UHR TB PPDU, the L-STF, L-LTF, L-SIG, and U-SIG are called the pre-UHR modulation field; the UHR-STF, UHR-LTF, Data, and PE are called the UHR modulation field. The duration of the UHR-STF field in a UHR TB PPDU is twice that of the UHR-STF field in a UHR MU PPDU.

In addition, in each example of the present application, punching can also be performed from high to low frequency, which is similar to the principle of punching from low to high frequency and will not be repeated. Figure 6 also includes null subcarriers. In an embodiment of the present application, the pilot subcarrier participates in the formation of RU or MRU, and the null subcarrier does not participate in the formation of RU or MRU. Null subcarriers are located near the DC (Direct Current) subcarriers or edge tones to provide protection from transmit center frequency leakage, receiver DC offset, and interference from neighboring RU(s) or MRU(s). The energy of null subcarriers is 0, and the energy of punctured subcarriers is also 0.
