1. A distributed antenna system, comprising:

  • a head-end unit including a time-division duplexing (“

    TDD”

    ) mode scheduler configured to identify a start of a downlink radio block that includes frequency-division duplexing signals based on monitoring a downlink communications channel and generate an indication of a TDD transmission time-slot based on detection of the start of the downlink radio block; and

    a remote unit configured to receive an uplink radio block on an uplink communications channel and transmit the downlink radio block on the downlink communications channel, the remote unit including a transmit/receive controller configured to receive the indication of the TDD transmission time-slot and in response to the indication, increase a downlink gain of the downlink radio block during the TDD transmission time-slot, and reduce an uplink gain of the uplink radio block during the TDD transmission time-slot.
