Methods and systems are provided for dynamically adjusting the power supplied to an antenna system. The dynamic adjustment of power is based on a total load of an antenna system and a quality of service class identifier (QCI) value. When the total load and the load of the QCI value identifier (e.g., QCI-1) are below a predefined threshold, the power supply to the antenna system can be adjusted. The adjustment can be a complete shut-down of the entire power supply. The adjustment can be a gradual reduction in the power supply provided to the antenna system. The power supply may be adjusted with respect to the entire antenna system, an antenna array of the antenna system, a node of the antenna array, an antenna element of the node, and the like.
