Abstract
A method implemented by a wireless fronthaul unit, the method comprising aggregating a plurality of first wireless channel signals to produce a first aggregated signal via digital frequency-domain mapping (FDM), wherein the first wireless channel signals are positioned in the first aggregated signal in non-overlapping first frequency bands with unchanged channel bandwidths (BWs), converting the first aggregated signal into a first modulated signal, and transmitting the first modulated signal to a wireless fronthaul link.
