Abstract

A method for indicating TXOP duration in a wireless communication system, comprising: generating, by a TXOP holder, a physical layer protocol data unit (PPDU), the High Efficiency Signal field A (HE-SIGA) in the PPDU carries a TXOP duration field, wherein the TXOP duration field is used to indicate the remaining time for using the channel by the station to other stations; wherein the TXOP duration field includes a first part which is used to indicate the granularity used, and a second part which is used to indicate the TXOP duration using the granularity indicated by the first part; so as that different granularities are able to be used to indicate different TXOP duration in the system; sending, the generated PPDU.
