1. A system for enhancing a wireless connection between a base station and a user equipment (UE), the system comprising:
a plurality of antenna elements configured to transmit one or more downlink signals from the base station to the UE, the plurality of antenna elements comprising a first set of antenna elements and a second set of antenna elements; and
one or more computer processing components configured to perform operations comprising:
determining that one or more UE-specific parameters of a first connection between the base station and the UE satisfies one or more UE-specific thresholds, the first connection comprising a first set of signals transmitted from the first set of antenna elements and having a first polarization;
determining that one or more radio environment parameters of a coverage area comprising the UE satisfies one or more radio environment thresholds; and
based on said determinations, transmitting a second set of signals to the UE using the second set of antenna elements, wherein the second set of signals has a second polarization, the first polarization being different than the second polarization.
