1. A base station device, comprising:
a processor; and
a memory that stores executable instructions that, when executed by the processor, facilitate performance of operations by the processor, comprising:
determining passive intermodulation interference corresponding to uplink signals that have been received, via a configurable cellular antenna array of the base station device, from respective wireless devices of a group of wireless devices that have been communicatively coupled to the base station device; and
selecting a defined configuration of a group of cellular antenna ports of the configurable cellular antenna array to facilitate a reduction of the passive intermodulation interference corresponding to the uplink signals, wherein selecting the defined configuration of the group of cellular antenna ports comprises, in response to determining that an uplink communication range of an uplink channel corresponding to the uplink signals is lower than a downlink communication range of a downlink channel corresponding to downlink sector beams that have been transmitted to the group of wireless devices, reconfiguring a portion of cellular antenna ports of the group of cellular antenna ports corresponding to the downlink channel to facilitate an increase of the uplink communication range.
