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.

Claims

1. A method of operating a terminal device for communicating with a base station in a telecommunications system over a radio interface supporting a downlink shared channel for conveying user-plane data from the base station to the terminal device and a downlink control channel for conveying control-plane data from the base station to the terminal device, wherein the control-plane data conveys information on physical resource allocations for the downlink shared channel for the terminal device, and wherein the radio interface is based on a radio frame structure comprising a plurality of subframes, wherein each subframe comprises a control region for supporting the downlink control channel and a user-plane region for supporting the downlink shared channel, and wherein the method comprises receiving in the control region of a first radio subframe an indication of a physical resource allocation for the terminal device on the shared downlink channel in the user-plane region of a second radio subframe, and subsequently receiving user-plane data on the physical resource allocation for the terminal device on the shared downlink channel in the user-plane region of the second radio subframe.

2. The method of claim 1, wherein the second radio subframe is received a predefined interval after the first radio subframe.

3. The method of claim 2, wherein the predefined interval is of a duration which corresponds with a predefined number of subframes.

4. The method of claim 1, wherein second radio subframe is received a selectable interval after the first radio subframe and the physical resource allocation for the terminal device is received in association with an indication of a selected interval.

5. The method of claim 2, wherein the indication of the selected interval comprises an indication of a number of subframes.

6. The method of claim 1, wherein the control region of the first radio subframe is further used to convey a physical resource allocation for a further terminal device on the shared downlink channel in the user-plane region of the first radio subframe.

7. The method of claim 6, wherein the terminal device is a terminal device of a first type and the further terminal device is a terminal device of a second type, the second type being different from the first type.

8. The method of claim 6, wherein the physical resource allocation for the terminal device is received using a first format for conveying control-plane data and the physical resource allocation for the further terminal device is in a second format for conveying control-plane data, the second format being different from the first format.

9. The method of claim 6, wherein the physical resource allocation for the terminal device is received using a first format for conveying control-plane data and the physical resource allocation for the further terminal device is in a second format for conveying control-plane data, the second format being the same as the first format.
