Allocating resources in a telecommunications system

摘要

A â virtual carrierâ 501 is inserted in a conventional OFDM type downlink carrier (â host carrierâ ) where the virtual carrier is a sub-range of the frequency range of the conventional downlink. Data transmitted on the virtual carrier can be received and decoded without needing to process the full bandwidth of the downlink host OFDM carrier. Accordingly data transmitted on the virtual carrier can be received and decoded using a reduced complexity receiver unit such as one for machine type communications (MTC).
