Method and system for achieving wireless communication between a sender device and a receiver device by means of a repeater device, without loss of information on a physical property

1. A method for wireless communication between a transmitter device and a receiver device via a repeater device, the transmitter device transmitting a message in a frequency band which is received by the repeater device, the repeater device retransmitting the message in the frequency band to the receiver device, the method comprises:

measuring, with the repeater device, a value of a first physical property of the message received from the transmitter device;

determining, with the repeater device and as a function of the value of the first physical property measured for the message, a value of a second physical property to be used for the retransmission of the message, the second physical property being different from the first physical property; and

retransmitting, with the repeater device, the message to the receiver device, using the value of the second physical property.

2. The method of claim 1 , wherein the value of the second physical property of the message retransmitted is determined such that a difference between the value of the second physical property of the message retransmitted and a predetermined reference value of the second physical property is representative of a difference between a reference value of the first physical property and the value of the first physical property measured for the message received.

3. The method of claim 2 , further comprising forming and transmitting, with the repeater device, a reference message using the predetermined reference value of the second physical property.

4. The method of claim 1 , further comprising:

measuring, with the receiver device, the value of the second physical property of the message received from the repeater device; and

determining, with the receiver device, the value of the first physical property of the message received by the repeater device as a function of the value of the second physical property measured for the message received by the receiver device.

5. The method of claim 1 , wherein the first physical property is a time at which the message is received by the repeater device; and the second physical property is one of the following physical properties: a frequency on which the message is retransmitted; a power with which the message is retransmitted; and a phase with which said message is retransmitted.

6. The method of claim 1 , wherein the first physical property is a power with which the message is received by the repeater device; and the second physical property is one of the following physical properties: a time at which the message is retransmitted; a frequency on which the message is retransmitted; and a phase with which the message is retransmitted.

7. The method of claim 1 , wherein the first physical property is a frequency on which the message is received by the repeater device; and the second physical property is one of the following physical properties: a time at which the message is retransmitted; a power with which the message is retransmitted; and a phase with which the message is retransmitted.

8. A repeater device configured to receive a message transmitted in a frequency band by a transmitter device and to retransmit the message in the frequency band to a receiver device, the repeater device comprising:

a processing circuit to measure a value of a first physical property of the message received from the transmitting device and to determine, as a function of the value of the first physical property measured for the message, the value of a second physical property to be used for retransmission of the message, the second physical property being different from the first physical property; and

a transmitter to retransmit the message to the receiver, using the value of the second physical property determined as a function of the value of the first physical property.

9. The repeater device of claim 8 , wherein the processing circuit is configured to determine the value of the second physical property of the message retransmitted such that a difference between the value of the second physical property of the message retransmitted and a predetermined reference value of the second physical property is representative of a difference between a reference value of the first physical property and the value of the first physical property measured for the message received.

10. The repeater device of claim 9 , wherein the processing circuit is configured to form a reference message using the predetermined reference value of the second physical property; and wherein the transmitter is configured to transmit the reference message.

11. A wireless communication system comprising a receiver device and a repeater device of claim 8 , wherein the receiver device comprises a processing circuit configured to:

measure a value of the second physical property of the message received from the repeater device; and

determine the value of the first physical property of the message received by the repeater device as a function of the value of the second physical property measured for the message received by the receiver device.
