Abstract

A radio frequency communication device ( 100 A) comprising a radio frequency communication interface ( 130 ) and a controller ( 110 ), wherein said controller ( 110 ) is configured to: transmit a message through said radio frequency communication interface ( 130 ) to a receiving radio frequency communication device ( 100 B) using a transmission format; receive an indication on whether the reception of the message is primarily limited by noise (N) or interference (I); adapt said transmission format; and retransmit said message using said adapted transmission format.

First claim

The invention claimed is:

1. A radio frequency communication device comprising:
a radio frequency communication interface; and
a controller, wherein said controller is configured to:
transmit a message through said radio frequency communication interface to a receiving radio frequency communication device using a transmission format;
receive an indication that indicates one of two possible types of primary limitation to the reception of the message, the two possible types of primary limitation to the reception of the message being noise-limited and interference-limited, from said receiving radio frequency communication device;
adapt said transmission format based upon the received indication; and
retransmit said message using said adapted transmission format.

2. The radio frequency communication device of claim 1 , wherein said controller is further configured to:
receive an indication of a type of interference limiting the reception of the message;
adapt a time for transmission based on said type of interference; and
retransmit said message at said adapted transmission time.

3. The radio frequency communication device of claim 1 , wherein said indication is part of an acknowledgment message being sent by the receiving radio frequency communication device in response to receiving the corresponding message to the transmitting radio frequency communication device.

4. The radio frequency communication device of claim 1 , wherein said indication is part of a message comprising ACK/NACK bits.

5. The radio frequency communication device of claim 1 , wherein said indication further includes an indication on the severity of the interference.

6. The radio frequency communication device of claim 5 , wherein said indication on the severity of the interference includes an indication on an increase in transmitting power for a reception to be successful.

7. The radio frequency communication device of claim 1 , wherein said indication further includes an indication on the type of the interference.

8. The radio frequency communication device of claim 7 , wherein said indication on the type of the interference is binary coded to indicate if the interference is of a same radio access technology used by the radio frequency communication device or of another radio access technology.

9. The radio frequency communication device of claim 7 , wherein the indication on the type of the interference indicates a standard, wherein the transmission causing the interference is being transmitted according to said standard, and wherein the standard is taken from a group of standards comprising: IEEE 802.11 (WiFi), IEEE 802.15.4 (ZigBee), Bluetooth®, NFC (Near Field Communication) or other short range (radio frequency) communication interface, RFID (Radio Frequency Identification), Sigfox, Universal Mobile Telecommunications System (UMTS), 3GPP Long Term Evolution (LTE), High Speed Packet Access (HSPA), or Global System for Mobile communication (GSM).

10. The radio frequency communication device of claim 7 , wherein the indication on the type of the interference indicates a type operating in an unlicensed band.

11. The radio frequency communication device of claim 10 , wherein said type operating in an unlicensed band is a type operating in an industrial, scientific and medical (ISM) band.

12. A radio frequency communication device comprising:
a radio frequency communication interface; and
a controller, wherein said controller is configured to:
receive a message through said radio frequency communication interface from a transmitting radio frequency communication device;
determine a primary cause of limitation to reception of the received message, wherein the primary cause of limitation is exactly one of either noise or interference;
transmit an indication of the primary cause of limitation to said transmitting radio frequency communication device; and
receive a retransmitted version of said message having been transmitted from said transmitting radio frequency device using an adapted transmission format.

13. The radio frequency communication device of claim 12 , wherein said controller is further configured to analyze said received message to determine the primary cause of limitation.

14. The radio frequency communication device of claim 12 , wherein said controller is further configured to determine a time indicator based on a type of interference and transmit said time indicator to said transmitting radio frequency communication device.

15. The radio frequency communication device of claim 12 , wherein said indication is part of an acknowledgment message being sent by the receiving radio frequency communication device in response to receiving the corresponding message to the transmitting radio frequency communication device.

16. The radio frequency communication device of claim 12 , wherein said indication is part of a message comprising ACK/NACK bits.

17. The radio frequency communication device of claim 12 , wherein said indication further includes an indication on the severity of the interference.

18. The radio frequency communication device of claim 17 , wherein said indication on the severity of the interference includes an indication on an increase in transmitting power for a reception to be successful.

19. The radio frequency communication device of claim 12 , wherein said indication further includes an indication on the type of the interference.

20. The radio frequency communication device of claim 19 , wherein said indication on the type of the interference is binary coded to indicate if the interference is of a same radio access technology used by the radio frequency communication device or of another radio access technology.

21. The radio frequency communication device of claim 19 , wherein the indication on the type of the interference indicates a standard, wherein the transmission causing the interference is being transmitted according to said standard, and wherein the standard is taken from a group of standards comprising: IEEE 802.11 (WiFi), IEEE 802.15.4 (ZigBee), Bluetooth®, NFC (Near Field Communication) or other short range (radio frequency) communication interface, RFID (Radio Frequency Identification), Sigfox, Universal Mobile Telecommunications System (UMTS), 3GPP Long Term Evolution (LTE), High Speed Packet Access (HSPA), or Global System for Mobile communication (GSM).

22. The radio frequency communication device of claim 19 , wherein the indication on the type of the interference indicates a type operating in an unlicensed band.

23. The radio frequency communication device of claim 22 , wherein said type operating in an unlicensed band is a type operating in an industrial, scientific and medical (ISM) band.

24. A method for use in a radio frequency communication device comprising a radio frequency communication interface, wherein said method comprises:
transmitting a message through said radio frequency communication interface to a receiving radio frequency communication device using a transmission format;
receiving an indication that indicates one of two possible types of primary limitation to the reception of the message, the two possible types of primary limitation to the reception of the message being noise-limited and interference-limited, from said receiving radio frequency communication device;
adapting said transmission format based upon the received indication; and
retransmitting said message using said adapted transmi
