Claim 13:
14. An apparatus, comprising:
at least one processor coupled to at least one non-transitory memory storing programming instructions for execution by the at least one processor to perform operations comprising:
generating a trigger frame, wherein the trigger frame comprises an uplink length field, and the uplink length field is used to indicate lengths indicated by legacy signal (L-SIG) fields in a high efficient trigger based physical layer protocol data unit (HE TB PPDU) and an extremely high throughput physical layer protocol data unit (EHT PPDU), or the uplink length field is used to indicate a length indicated by an L-SIG field in an EHT PPDU;
sending the trigger frame; and
determine a received PPDU is an EHT PPDU according to a length indicated in an L-SIG field in the received PPDU is a multiple of three.
