Abstract

A method operating a telecommunications system including a base station and plural terminal devices arranged to communicate over a radio interface supporting a downlink shared channel conveying user-plane data from the base station to the terminal devices and a downlink control channel conveying control-plane data from the base station to the terminal devices. The control-plane data conveys information on physical resource allocations for the downlink shared channel for respective of the terminal devices. The radio interface is based on a radio frame structure including plural subframes each including a control region supporting the downlink control channel and a user-plane region supporting the downlink shared channel. The method uses the control region of a first radio subframe to convey an indication of a physical resource allocation for a first terminal device on the shared downlink channel in the user-plane region of a second radio subframe subsequent to the first radio subframe.
