Abstract: The present specification proposes an example in which different types of Physical Protocol Data Units (PPDUs) are aggregated. Different types of PPDUs may be included in one aggregated PPDU (A-PPDU). Different types of PPDUs may be composed of the same version of the PPDUs or may be composed of different versions of the PPDUs. Different types of PPDUs may be allocated to a primary channel or a non-primary channel. Different types of PPDUs may be allocated to various frequency bands. Broadband communication can be supported compared to the related art through one A-PPDU including different types. In addition, through the additional technical features proposed in the present specification, efficient communication for receiving STAs of different standards is possible.
