Eht station configured for signalling a txop duration in txop field

Abstract

Embodiments of an Extremely High Throughput Station (EHT STA) (STA1) configured for operating in a next-generation (NG) wireless local area network (WLAN) are described herein. In some embodiments, the EHT STA encodes a common signal field (SIG) (Coex-SIG) of an EHT PPDU to include a TXOP duration field. The TXOP duration field is more than seven bits to indicate an actual TXOP duration of a transmission from the EHT STA comprising the EHT PPDU transmitted to a second station (STA2). Decoding the TXOP duration field of the EHT PPDU by a third-party station (STA4) causes the third-party station (STA4) to defer a transmission until after an end of the transmission from the second station (STA2).
