摘要：
A unit includes circuitry configured to: receive a downlink signal; sub-divide the downlink signal into a sub-divided downlink signal having downlink signal components in a time domain, each downlink signal component corresponding to a respective sub-band; determine that at least one downlink signal component corresponds to at least one sub-band having data to be transmitted via a distributed antenna system; generate a transformed downlink signal representing the downlink signal in a frequency domain by performing a frequency transform on the downlink signal; determine that the at least one sub-band of the transformed downlink signal includes the data to be transmitted; extract the at least one sub-band from the transformed downlink signal at least in part by providing data for at least one portion of the transformed downlink signal in the frequency domain that corresponds to the at least one sub-band to the at least one remote antenna unit.
