Abstract

A method of allocating radio resources for uplink transmissions in a wireless telecommunications system, the method including: a first terminal device communicating a request for an allocation of radio resources to a base station; the base station determining there is an association between the first terminal device and a second terminal device based on their having similar predicted traffic profiles for uplink data; and the base station establishing a radio resource allocation for the second terminal device based on the resources requested by the first terminal device, and consequently transmitting radio resource allocation messages to allocate radio resources to the first and the second terminal devices for respective uplink transmissions based on the request for an allocation of radio resources received from the first terminal device.

Claims

1. A method of operating a terminal device for receiving an allocation of radio resources for transmission of uplink data to a base station in a wireless telecommunications system, the method comprising:

determining that the terminal device has uplink data waiting for transmission to the base station;

determining that the terminal device should not transmit a request for an allocation of radio resources for transmission of the uplink data to the base station, and

waiting to receive a radio resource allocation message from the base station to allocate radio resources to be used for transmissions associated with the uplink data waiting for transmission to the base station.

2. A method according to claim 1, wherein determining that the terminal device should not transmit a request for an allocation of radio resources comprises determining that the terminal device should not initiate a random access procedure of the wireless telecommunications system.

3. A method according to claim 2, wherein determining that the terminal device should not initiate a random access procedure of the wireless telecommunications system comprises determining that the terminal device should not make transmissions on a physical random access channel of the wireless telecommunications system.

4. A method according to claim 1, wherein determining that the terminal device should not transmit a request for an allocation of radio resources is based on the terminal device receiving an indication that the terminal device should not transmit a request for an allocation of radio resources.

5. A method according to claim 4, wherein the indication comprises an indication that another terminal device in the wireless telecommunications system has made a request for an allocation of radio resources.

6. A method according to claim 1, wherein determining that the terminal device should not transmit a request for an allocation of radio resources is based on the terminal device having received an access request denial message from the base station.

7. A method according to claim 1, further comprising subsequently receiving the radio resource allocation message from the base station.

8. A method according to claim 7, further comprising transmitting the uplink data waiting for transmission to the base station using radio resources derived from information in the radio resource allocation message received from the base station.

9. A method according to claim 8, further comprising determining at a later time after having transmitted the uplink data to the base station that the terminal device has further uplink data waiting for transmission to the base station, and, in response thereto, determining that the terminal device should transmit a request for an allocation of radio resources on which to transmit the uplink data to the base station, and transmitting such a request.

10. A method according to claim 9, wherein determining that the terminal device should transmit a request for an allocation of radio resources in response to determining that the terminal device has further uplink data waiting for transmission to the base station is based on the terminal device having received an access request allow message from the base station to indicate the terminal device is allowed to make a request for an allocation of radio resources.

11. A method according to claim 7, further comprising determining that the allocation of radio resources is not sufficient for the uplink data waiting for transmission to the base station and transmitting to the base station an indication of a request for a further allocation of radio resources in response thereto.

12. A method according to claim 11, wherein the indication of a request for a further allocation of radio resources is transmitted to the base station using the allocated radio resources.

13. A method according to claim 1, further comprising transmitting a request for an allocation of radio resources on which to transmit the uplink data to the base station after waiting to receive a radio resource allocation message from the base station for a period of time without a radio resource allocation message being received from the base station.

14. A method according to claim 1, wherein the terminal device is a machine type communication, MTC, terminal device.

15. A method according to claim 1, wherein the wireless telecommunications system is associated with a radio interface spanning a system frequency bandwidth for supporting radio communications with a first type of terminal device and comprising a restricted frequency bandwidth for supporting radio communications with a second type of terminal device, wherein the restricted frequency bandwidth is narrower than and within the system frequency bandwidth, and wherein the terminal device is a terminal device of the second type.

16. A terminal device arranged to receive an allocation of radio resources for transmission of uplink data to a base station in a wireless telecommunications system, wherein the terminal device is configured to:

determine that the terminal device has uplink data waiting for transmission to the base station;

determine that the terminal device should not transmit a request for an allocation of radio resources for transmission of the uplink data to the base station, and

wait to receive a radio resource allocation message from the base station to allocate radio resources to be used for transmissions associated with the uplink data waiting for transmission to the base station.

17.

18. A terminal device according to claim 17, wherein the terminal device is configured such that determining that the terminal device should not initiate a random access procedure of the wireless telecommunications system comprises determining that the terminal device should not make transmissions on a physical random access channel of the wireless telecommunications system.

19. A terminal device according to claim 16, wherein the terminal device is configured such that determining that the terminal device should not transmit a request for an allocation of radio resources is based on the terminal device receiving an indication that the terminal device should not transmit a request for an allocation of radio resources.

20. A terminal device according to claim 19, wherein the indication comprises an indication that another terminal device in the wireless telecommunications system has made a request for an allocation of radio resources.

21. A terminal device according to claim 16, wherein the terminal device is configured such that determining that the terminal device should not transmit a request for an allocation of radio resources is based on the terminal device having received an access request denial message from the base station.

22. A terminal device according to claim 16, wherein the terminal device is further configured to subsequently receive the radio resource allocation message from the base station.
