1. A method comprising:
sub-dividing a downlink signal into a sub-divided downlink signal having a plurality of downlink signal components in a time domain, wherein each of the plurality of downlink signal components corresponds to a respective sub-band;
determining that at least one component of the plurality of downlink signal components corresponds to at least one sub-band having data to be transmitted via a distributed antenna system;
generating, subsequent to determining that the at least one component from the sub-divided downlink signal corresponds to the at least one sub-band, a transformed downlink signal by performing a frequency transform on the downlink signal, wherein the transformed downlink signal represents the downlink signal in a frequency domain;
determining that the at least one sub-band of the transformed downlink signal includes the data to be transmitted; and
extracting the at least one sub-band from the transformed downlink signal for transmission via the distributed antenna system, wherein extracting the at least one sub-band from the transformed downlink signal comprises:
providing, by the unit, data for at least a portion of the transformed downlink signal in the frequency domain that corresponds to the at least one sub-band to at least one remote antenna unit of the distributed antenna system.
