A terminal device is described which communicates with a base station supporting a host carrier comprising radio resource segments distributed in time, each radio resource segment providing radio resources across a first frequency band. The terminal device is operable to communicate with said base station using a subordinate carrier comprising radio resources within a second frequency band of a subset of the radio resource segments of the host carrier, the second frequency band being narrower than and contained within the first frequency band. In this way, an efficient and flexible mechanism for specifying and controlling an amount and location of radio resources to be dedicated to a subordinate carrier for use by a particular (e.g. reduced capability) type of device can be provided. An embodiment describes mobile-to-mobile (M2M) or machine-type-communication (MTC) devices utilising the narrow second frequency band within a typical Long Term Evolution (LTE) network. |
