Abstract
An access point (AP), a station (STA), and a wireless communication method are provided. The method includes receiving, by a STA (e.g., an EHT STA), a physical layer protocol data unit (PPDU) which carries one or more trigger frames for performing a high efficiency (HE) trigger-based (TB) PPDU transmission or an extremely high efficiency (EHT) TB PPDU transmission of a TB aggregate PPDU (A-PPDU) transmission to an AP. In another embodiment, the method includes receiving, by an EHT STA, a PPDU which carries two or more aggregate medium access control (MAC) protocol data units (A-MPDUs) for performing any of one or more HE TB PPDU transmission and one or more EHT TB PPDU transmission of a TB A-PPDU transmission to an AP.
