1. A method for supporting multi-signal source communications in a distributed communications system (DCS), comprising:
receiving, in a routing circuit from each signal source among a plurality of signal sources, where each signal source among the plurality of signal sources comprises a number of baseband units (BBUs) equal in number to a plurality of logical channels, a plurality of downlink frequency-domain signals, the plurality of downlink frequency-domain signals each comprising a respective one of the plurality of logical channels;
generating, in the routing circuit, a plurality of downlink frequency-domain communications signals each comprising a plurality of selected logical channels among the one or more logical channels associated with each of the plurality of signal sources;
receiving, in a remote unit, a respective one of the plurality of downlink frequency-domain communications signals;
converting, in the remote unit, the respective one of the plurality of downlink frequency-domain communications signals into a downlink time-domain communications signal comprising the one or more selected logical channels; and
transmitting, from the remote unit, a respective one of a plurality of downlink radio frequency (RF) communications signals comprising the downlink time-domain communications signal.
