Abstract

A method transmits information in a communication system. The method includes transmitting information from a transmitting device to a receiving device through a communication channel, checking whether the receiving device has received the information without errors, and transmitting an acknowledgement notification from the receiving device to the transmitting device if the receiving device has received the information without errors. The acknowledgement notification includes an indication of a capability of the receiving device to receive further information from the transmitting device.

Claims

1. A method of transmitting information in a communication system, the method comprising:

transmitting information from a transmitting device to a receiving device through a communication channel;

checking whether the receiving device has received the information without errors; and

transmitting an acknowledgement notification from the receiving device to the transmitting device if the receiving device has received the information without errors, wherein the acknowledgement notification comprises an indication of a capability of the receiving device to receive further information from the transmitting device.

2. The method of claim 1, wherein the acknowledgement notification is transmitted from the receiving device to the transmitting device if a frame of information has been received by the receiving device without errors.

3. The method of claim 2, wherein the acknowledgement notification is transmitted from the receiving device to the transmitting device as an immediate acknowledgement frame notification.

4. The method of claim 2, wherein the acknowledgement notification is transmitted from the receiving device to the transmitting device as a burst acknowledgement frame notification.

5. The method of claim 1, wherein the acknowledgement notification comprises information on a maximum number of additional frames which can be received by the receiving device from the transmitting device.

6. The method of claim 1, wherein the acknowledgement notification comprises information on a free buffer size of the receiving device available for receiving further information from the transmitting device.

7. The method of claim 1, comprising:

checking the capability of the receiving device to receive further information by the transmitting device.

8. The method of claim 7, comprising:

transmitting a queue polling request from the transmitting device to the receiving device to check a queue status of the receiving device.

9. The method of claim 8, wherein the queue polling request is transmitted by a media access controller layer of the transmitting device.

10. The method of claim 8, wherein the acknowledgement notification is transmitted from the transmitting device to the receiving device after having received the queue polling request and having checked the status of at least one queue of the receiving device.

11. The method of claim 1, further comprising:

transmitting a result of the checking from the receiving device to the transmitting device.

12. A communication system, comprising

a communication channel;

a transmitting device coupled to the communication channel and configured to transmit information through the communication channel; and

a receiving device coupled to the communication channel and configured to receive the information transmitted from the transmitting device through the communication channel, the receiving device configured to check whether the receiving device has received the transmitted information from the transmitting device without errors and to send an acknowledgement notification to the transmitting device if the transmitted information is received without errors, wherein the acknowledgement notification comprises an indication of a capability of the receiving device to receive further information from the transmitting device.

13. The communication system of claim 12, wherein the receiving device is configured to transmit the acknowledgement notification to the transmitting device as an immediate acknowledgement frame notification.

14. The communication system of claim 12, wherein the receiving device is configured to transmit the acknowledgement notification to the transmitting device as a burst acknowledgement frame notification.

15. The communication system of claim 12, wherein the acknowledgement notification comprises information on a maximum number of additional frames which can be received by the receiving device from the transmitting device.

16. The communication system of claim 12, wherein the acknowledgement notification comprises information on a free buffer size of the receiving device available for receiving further information from the transmitting device.

17. The communication system of claim 12, wherein the communication system is a communication system according to the ultra-wideband technology.

18. The communication system of claim 12, wherein the communication system is a communication system according to the multiband OFDM alliance standard.

19. The communication system of claim 12, wherein the receiving device comprises a media access controller layer configured to transmit the acknowledgement notification.

20. The communication system of claim 19, wherein the transmitting device comprises higher layers configured to receive the acknowledgement notification transmitted by the media access control layer of the receiving device.

21. A communication system, comprising

a communication channel;

means for transmitting information through the communication channel; and

means for receiving the information transmitted through the communication channel, including;

means for checking whether the receiving device has received the transmitted information from the transmitting device without errors; and

means for sending an acknowledgement notification to the transmitting device if the transmitted information is received without errors, wherein the acknowledgement notification comprises an indication of a capability of the receiving device to receive further information from the transmitting device.

22. A receiving device comprising:

a receiver unit configured to receive information from a transmitting device through a communication channel;

a control unit configured to check whether the receiving device has received the transmitted information from the transmitting device without errors; and

a sender unit configured to send an acknowledgement notification to the transmitting device if the transmitted information is received without errors, wherein the acknowledgement notification comprises an indication of a capability of the receiving device to receive further information from the transmitting device.

23. The receiving device of claim 22, comprising:

a transceiver unit including the receiver unit and the sender unit.

24. A receiving device comprising:

means for receiving information from a transmitting device through a communication channel;

means for checking whether the receiving device has received the transmitted information from the transmitting device without errors; and

means for sending an acknowledgement notification to the transmitting device if the transmitted information is received without errors, wherein the acknowledgement notification comprises an indication of a capability of the receiving device to receive further information from the transmitting device.
