Abstract
A wireless communication device includes first and second links. The first and second links respectively include first and second sets of antennae having an arrangement that renders a null space of a channel matrix between the first and second links non-zero. When the first and second links operate on a first frequency band, the first link obtains first channel state information that indicates a first channel measurement of a first set of channels observed from the second link to the first link. Based on the first channel state information, the first link determines a spatial mapping matrix that facilitates null steering of a signal transmission from the first link in a direction of the second link. The first link transmits to a remote device, a wireless signal on the first frequency band based on the spatial mapping matrix.
