Example Embodiment
[0328] Example two
[0329] In the embodiment of the present application, the second AP is any AP that can assist the first AP to send data to the first STA. Based on the description of the first embodiment above, in the first embodiment, the first AP has determined the identity of the second AP providing transmission assistance, and can directly interact with the second AP with SOMA signaling information, so as to obtain the PPDU when generating the PPDU. Consistent leading field. In an actual application scenario, when the first AP determines that it needs assistance in sending data to the first STA, it may not directly send the first indication information. Instead, it may negotiate with the second AP to determine the joint transmission mode before sending the first indication. An indication information to exchange SOMA signaling information of both parties.
[0330] Therefore, the embodiment of the present application further provides another joint transmission method based o...
Example Embodiment
[0353] Example three
[0354] In the first and second embodiments described above, at least one of the first AP and the second AP uses SOMA modulation to send data to two STAs in parallel. Taking the first AP sending data to the first STA and the second STA in parallel as an example, in an actual application scenario, the data length of the first data information of the first STA and the second data information of the second STA may not be the same. In this way, when performing SOMA modulation on the first data information and the second data information, it is necessary to use padding to match the inconsistency of the data length of the two.
[0355] Figure 18 Exemplarily shows the padding in the first PPDU provided in the first and second embodiments, such as Figure 18 As shown, if the data length of the first data information is greater than the data length of the second data information, the insufficient part of the second data information needs to be filled. The length of t...
