Abstract:
An apparatus and method providing feedback on channel conditions in a wireless telecommunications system including a base station to communicate with plural terminals device using frequencies spanning a system frequency bandwidth. At least one terminal device is a reduced capability terminal device including a tuneable transceiver configured to receive downlink transmissions from the base station using only a restricted frequency bandwidth smaller than and within the system frequency bandwidth. The reduced capability terminal device is configured to communicate information derived from measurements of channel conditions to the base station. The information may include an indication of measured channel conditions for different frequency locations, or an indication of one or more frequency locations for which corresponding measurement of channel conditions meet a pre-defined selection criterion. The base station subsequently schedules downlink transmissions for the terminal device in a manner that takes account of the information received from the terminal device.
