Abstract
An apparatus, system, and method for mitigating interference within an actively used spectrum. For example, one embodiment of a system comprises: a first wireless network operating with a first protocol and comprising a plurality of wireless transceiver stations that share a cell ID and collectively transmit a plurality of simultaneous non-interfering precoded data streams to a plurality of user equipment (UE) within the same frequency band, a second wireless network operating with a second protocol and comprising one or a plurality of antennas, wherein the first wireless network creates one or a plurality of points of zero radio frequency (RF) energy at the location of the one or at least one of the plurality of antennas.
