Abstract
This document discloses a solution for sharing a transmission opportunity in a wireless network. According to an aspect, a method for an apparatus of a first wireless network includes determining a plurality of devices of a second wireless network for null steering; transmitting a trigger frame, the trigger frame indicating a transmission period for data frame transfer between the apparatus and another apparatus of the first wireless network, a spatial reuse opportunity for the second wireless network during the transmission period, and an additional period preceding the transmission period; receiving, from at least one device of the second wireless network during the additional period, a channel state frame; and performing, based on the channel state frame, null steering towards the at least one device during the transmission period.
