1. An apparatus comprising:
at least one processor; and
at least one memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
detect that a second access node of a second wireless network is hidden to a first access node of a first wireless network;
in response to the detecting that the second access node is hidden to the first access node, transmit a message to the second access node;
wherein the message transmitted to the second access node comprises at least one parameter configured to request that spatial cooperation to be performed;
wherein the at least one parameter comprises a number of one or more antennas of the apparatus;
receive, from the second access node a response message comprising at least one information element acknowledging that spatial cooperation is to be performed; and
subsequent to receiving from the second access node the response message acknowledging that spatial cooperation is to be performed, receive a frame from the first access node while null steering is performed between the apparatus and the second access node;
wherein the apparatus is configured to operate in the first wireless network.
