1. An apparatus comprising:
at least one processor, and
at least one non-transitory memory storing instructions that, when executed by the at least one processor, cause the apparatus at least to:
receive a control request frame from a second access node of a second wireless network, where the apparatus is part of a first wireless network, and where the control request frame comprises at least a number of nulls for the apparatus,
select a subset of antenna elements, wherein the subset comprises a number of antenna elements in accordance with the number of nulls for the apparatus, and the antenna elements are selected to the subset based on reception powers of one or more antenna elements of at least a frame from at least one of a first access node of the first wireless network or the second access node of the second wireless network,
in response to receipt of the control request frame and selection of the subset of antenna elements, transmit a control response frame with the selected antenna elements, and
transmit a data frame to the first access node with the selected antenna elements.
