Selective non-distribution of received unlicensed spectrum communication signals by a remote unit(s) into a distributed communications system (DCS)

Selective non-distribution of received unlicensed spectrum communications by a remote unit(s) into a distributed communications system (DCS) is provided. In one aspect, the DCS is configured to receive communications signals in unlicensed spectrum from a source transceiver(s) for communications services. The DCS is configured to distribute the received communications signals in unlicensed spectrum to one or more remote units forming respective remote communications coverage areas. To reduce or avoid signal interference when communication signals in unlicensed spectrum are transmitted into the DCS that is also being used for transmissions by a remote transceiver to a remote unit at the same time, received communications signals by the remote units are monitored for unlicensed spectrum. The remote unit is configured to disable or disconnect the reception and/or transmission of the communications signals in the unlicensed spectrum based on the communication signal activity in the unlicensed spectrum.
