A Long Term Evolution (LTE) communication system dynamically controls Automatic Gain Control (AGC) in a repeater system serving individual User Equipment (UE). The LTE communication system identifies individual UEs and an application type used by the individual UEs being served by a repeater section in the repeater system. The LTE communication system determines a Variable Bit Rate (VBR)-to-Guaranteed Bit Rate (GBR) application ratio based on a number of the identified individual UEs using a VBR application and a number of the identified individual UEs using a GBR application. The LTE communication system compares the VBR-to-GBR application ratio to a VBR application threshold and determines that the VBR-to-GBR application ratio exceeds the VBR application threshold. In response to determining that the VBR-to-GBR application ratio exceeds the VBR application threshold, the LTE communication system instructs the repeater section in the repeater system to disable the AGC.
