Tower mounted amplifier (TMA) control based on user equipment (UE) concentration

A Radio Access Network (RAN) is configured to serve wireless User Equipment (UEs). The RAN comprises a Baseband Unit (BBU) and a Tower Mounted Amplifier (TMA). The BBU determines an amount of proximate wireless UEs that have transmit power levels that fall below a proximity threshold and when the amount of the proximate UEs exceeds a concentration threshold. When the proximate UEs exceeds the concentration threshold, the BBU schedules the proximate wireless UEs to use proximate UE Transmit Time Intervals (TTIs) and schedules other wireless UEs to use other TTIs. The BBU transfers control signals to deactivate TMA amplification during the proximate UE TTIs and to activate the TMA amplification during the other TTIs. The TMA receives UE signals, and in response to the control signals, deactivates TMA amplification on UE signals during the proximate UE TTIs and activates TMA amplification on UE signals during the other TTIs.
