Abstract

A method for sharing a wireless transmission medium in a terminal device between at least a first wireless communication technology and a second wireless communication technology and a wireless communication device and a wireless communication circuit related thereto, the first wireless communications technology being configured to set at least a first time frame for receiving a first signal via the first wireless communication technology at the terminal device, the first signal comprising a control region and a data region the control region indicating a schedule of the data region the method comprising: receiving at least the control region via the first wireless communication technology in the first time frame; interrupting reception of the first signal at least for the remainder of the first time frame after receiving the control region; and sending signals via the second wireless transmission technology within the first time frame after the reception of the first signal was interrupted.

First claim

What is claimed is:

1. A method for sharing a wireless transmission medium in a terminal device between at least a first wireless communication technology and a second wireless communication technology, the method comprising:
receiving in a first time frame at least a control region of a first signal via the first wireless communication technology, the first time frame being set by the first communication technology for receiving the first signal and the control region indicating a schedule of a data region in the first signal;
decoding the control region of first time frame;
interrupting reception of the first signal at least for a remainder of the first time frame after receiving the control region and before the control region is completely decoded by the terminal device;
sending a command from a first wireless communication circuit of the terminal device to a second wireless communication circuit of the terminal device, to allow the second communication circuit to send signals via the second wireless transmission technology within the first time frame after the reception of the first signal was interrupted, the first wireless communication circuit being configured to communicate via the first wireless communication technology and the second wireless communication circuit being configured to communicate via the second wireless communication technology; and
sending the signals via the second wireless transmission technology within the first time frame after the reception of the first signal was interrupted.

2. The method of claim 1 , wherein receiving the control region includes the decoding of the control region by the terminal device.

3. The method of claim 2 , wherein the control region is decoded after receiving the control region.

4. The method of claim 1 , wherein the reception of the first signal of the first wireless communication is interrupted before the decoding of the control region can determine if data is scheduled to be received by the terminal device within the first time frame.

5. The method of claim 4 , wherein the first wireless communication technology is configured to retransmit data not received by the terminal device in a subsequent time frame, the method further including:
preventing an interruption of reception of a subsequent signal of at least the subsequent time frame of the first wireless communication technology, when the decoding of the control region results in the information that data was scheduled to be received by the terminal device within the first time frame.

6. The method of claim 1 , wherein the first wireless communication technology is a cellular wide area communication technology.

7. The method of claim 6 , wherein the first wireless communication technology is a Long Term Evolution technology and the first time frame is an LTE subframe.

8. The method of claim 1 , wherein the second wireless communication technology is a short range communication technology.

9. The method of claim 8 , wherein the second wireless communication technology is a wireless local area network technology or a Bluetooth technology.

10. The method of claim 1 , wherein the control region is a leading part of the first signal.

11. The method of claim 10 , wherein the data region follows the control region.

12. A wireless communication device, comprising:
a first wireless communication circuit, configured to communicate according to a first wireless communication technology; and
a second wireless communication circuit, configured to communicate according to a second wireless communication technology;
the first wireless communication circuit being configured to receive in a first time frame at least a control region of a first signal via the first wireless communication technology, the first time frame being set by the first communication technology for receiving the first signal and the control region indicating a schedule of a data region in the first signal, to decode the control signal, and to interrupt reception of the first signal at least for a remainder of the first time frame after receiving the control region and before the control region is completely decoded, and the second wireless communication circuit being configured to send signals via the second wireless transmission technology within the first time frame after the reception of the first signal of the first wireless communication technology was interrupted.

13. The wireless communication device of claim 12 , wherein the first wireless communication circuit is configured to decode the control region after receiving the control region.

14. The wireless communication device of claim 12 , wherein the first wireless communication circuit is configured to interrupt the reception of the first signal before the decoding of the control region can determine if data is scheduled to be received by the terminal device within the first time frame.

15. The wireless communication device of claim 12 , wherein the first wireless communication technology is configured to retransmit unreceived data in a subsequent time frame, and wherein the first wireless communication circuit is configured to prevent an interruption of reception of a further signal of at least the subsequent time frame of the first wireless communication technology, when the decoding of the control region results in the information that data was scheduled to be received within the first time frame.

16. The wireless communication device of claim 12 , wherein the first wireless communication technology and the second wireless communication technology share the same wireless transmission medium.

17. The wireless communication device of claim 12 , wherein the control region is a leading part of the first signal.

18. The wireless communication device of claim 17 , wherein the data region follows the control region.

19. A wireless communication circuit for communicating according to a first wireless communication technology, comprising:
a reception circuit configured to receive in a first time frame at least a control region of a first signal via the first wireless communication technology and to decode the control region, the first time frame being set by the first communication technology for receiving the first signal and the control region indicating a schedule of a data region in the first signal;
a control circuit configured to interrupt the reception of the first signal after receiving the control region and before the control region is completely decoded; and
the control circuit being configured to send a command to at least a second wireless communication circuit, allowing the second wireless communication circuit to send signals via a second wireless transmission technology at least within the first time frame after reception of the first signal was interrupted.
