1. An apparatus comprising
at least one processor,
at least one memory storing instructions, that when executed by the at least one processor, cause the apparatus at least to:
receive from a first wireless device a first transmission comprising information on at least one of beamforming or null steering for a second transmission from the first wireless device,
wherein the first transmission comprises an omnidirectionally-transmitted preamble field of a physical layer protocol data unit to identify whether the second transmission is beamformed or null steered, and
wherein the information on at least one of beamforming or null steering comprises parameters indicative of at least one target area or direction of at least one null radiation null during the second transmission; and
enable, based on the information, a third transmission from a second wireless device to a third wireless device during the second transmission on the basis of the information on at least one of beamforming or null steering,
wherein the second transmission comprises a remaining frame or preamble portion of the physical layer protocol data unit.
