摘要: Methods and systems for supporting scalable bandwidth in radio telecommunications networks are provided. When signals are transmitted to user equipments using a transmitter of a radio telecommunication network, the signals are frequency multiplexed, each signal lying within a frequency band having an equal or narrower bandwidth than a reception bandwidth of each user equipment that is to receive a signal. Then the multiplexed signal is converted to a time domain signal.
