In another respect, disclosed is a cell site of a wireless communication system, the cell site comprising: a first antenna system; a second antenna system; a first remote radio head (RRH) connected by a first radio frequency (RF) path to the first antenna system, wherein the first RF path supports a first plurality of RF channels for air-interface communications with one or more user equipment device (UEs) via the first antenna system; a second RRH connected by a second RF path to the second antenna system, wherein the second RF path supports a second plurality of RF channels for air-interface communications with one or more UEs via the second antenna system; one or more processors, and memory storing instructions that, when executed by the one or more processors, cause the cell site to carry out operations including: making a determination that attenuation of antenna transmission power of a particular channel of the second plurality of RF channels exceeds attenuation of antenna transmission power of a particular channel of the first plurality of RF channels by more than a difference threshold; in response to the determination, identifying one or more other channels of the second plurality of RF channels for which capacity loading for serving UEs is below a utilization threshold; removing the identified one or more other channels from service; and at the second RRH, redistributing transmission power of the removed one or more other channels to the particular channel of the second plurality of RF channels to boost the transmission power of the particular channel of the second plurality of RF channels.
