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, the method comprising:

receiving, in a control region of a first radio subframe, an indication of a physical resource allocation for the terminal device on a shared downlink channel in an 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, wherein the second radio subframe is transmitted with a delay after transmitting the first radio subframe, the delay being adjusted dependent on a class type of the terminal device, wherein the class type includes at least a smartphone-type and a machine-type, the machine-type being semi-autonomous or autonomous wireless communication type terminal devices having bandwidth capabilities lower than smartphone-type terminal devices and the delay is increased when the class type is the machine-type.

2. 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.

3. The method of claim 2, 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.

4. The method of claim 2, 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.

5. The method of claim 2, 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.

6. A terminal device for communicating with a base station in a telecommunications system over a radio interface, the terminal device comprising:

a transmitter configured to transmit data to the base station over the radio interface; and

a receiver configured to receive, in a control region of a first radio subframe, an indication of a physical resource allocation for the terminal device on a shared downlink channel in an user-plane region of a second radio subframe and to subsequently receive 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, wherein the second radio subframe is transmitted with a delay after transmitting the first radio subframe, the delay being adjusted dependent on a class type of the terminal device, wherein the class type includes at least a smartphone-type and a machine-type, the machine-type being semi-autonomous or autonomous wireless communication type terminal devices having bandwidth capabilities lower than smartphone-type terminal devices and the delay is increased when the class type is the machine-type.

7. The terminal device of claim 6, wherein the control region of the first radio subframe also comprises a physical resource allocation for a further terminal device on the shared downlink channel in the user-plane region of the first radio subframe.

8. The terminal device of claim 7, 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.

9. The terminal device of claim 7, 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.

10. The terminal device of claim 7, 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.

11. The terminal device of claim 7, wherein the terminal device and further terminal device are of the same type.
