1. An apparatus for a first wireless network, comprising:
at least one processor; and
at least one non-transitory memory including computer program code,
the at least one non-transitory memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
determine a plurality of devices of a second wireless network for null steering;
transmit 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;
receive, from at least one device of the second wireless network during the additional period, a channel state frame; and
perform, based on the channel state frame, null steering towards the at least one device during the transmission period.
