Methods are provided for dynamically deactivating synchronization signal block (SSB) beams based on uplink noise. Uplink noise is monitored at a cell site over a configurable period of time. Upon the uplink noise being determined to be above a threshold value, SSB beams corresponding to user equipment that are contributing to the uplink noise are determined. Based on a magnitude of the uplink noise at the cell site, one or more SSB beams of the SSB beams are dynamically deactivated at the cell site.
