Abstract

A first terminal receives, on a radio link of a cellular network, at least one uplink pilot signal transmitted by at least one second terminal. The first terminal transmits, on the radio link and to an access node of the cellular network, an uplink report message indicative of at least one property of the received at least one uplink pilot signal.

First claim

The invention claimed is:

1. A method, comprising:
a first terminal receiving, on a radio link of a cellular network, at least one uplink pilot signal transmitted by at least one second terminal, and
the first terminal transmitting, on the radio link and to an access node of the cellular network, an uplink report message indicative of at least one property of the at least one uplink pilot signal that was received,
wherein the at least one uplink pilot signal comprises multiple pilot signals, and
wherein the uplink report message comprises an average of the at least one property of the multiple pilot signals.

2. The method of claim 1 ,
wherein the average of the at least one property of the multiple pilot signals comprises an average of an amplitude and/or a phase of the multiple pilot signals.

3. The method of claim 1 ,
wherein the at least one second terminal comprises multiple second terminals, and
wherein the average is determined for the at least one property of the multiple pilot signals received from the multiple second terminals.

4. The method of claim 1 ,
wherein the uplink report message is for channel sensing performed by the access node.

5. The method of claim 1 ,
wherein the uplink report message is indicative of an average signal amplitude on the radio link.

6. A method, comprising:
an access node of a cellular network receiving, on a radio link of the cellular network and from a first terminal, an uplink report message indicative of at least one property of at least one uplink pilot signal received by the first terminal, the at least one uplink pilot signal being transmitted by at least one second terminal,
wherein the at least one uplink pilot signal comprises multiple pilot signals, and
wherein the uplink report message comprises an average of the at least one property of the multiple pilot signals.

7. The method of claim 6 , further comprising:
performing channel sensing based on the uplink report message, to mitigate inter-cell interference.

8. The method of claim 6 ,
wherein the uplink report message is indicative of an average signal amplitude on the radio link.

9. The method of claim 6 ,
wherein the at least one second terminal comprises multiple second terminals, and
wherein the average is determined for the at least one property of the multiple pilot signals received from the multiple second terminals.

10. The method of claim 6 ,
wherein the uplink report message is for channel sensing performed by the access node.

11. An access node of a cellular network, comprising:
an interface configured to transceive on a radio link of the cellular network, and
at least one processor configured to receive, via the interface and from a first terminal, an uplink report message indicative of at least one property of at least one uplink pilot signal received by the first terminal, the at least one uplink pilot signal being transmitted by at least one second terminal,
wherein the at least one uplink pilot signal comprises multiple pilot signals, and
wherein the uplink report message comprises an average of the at least one property of the multiple pilot signals.

12. A terminal attachable configured to be attached to a cellular network, comprising:
an interface configured to transceive on a radio link of the cellular network, and
at least one processor configured to receive, via the interface, at least one uplink pilot signal transmitted by at least one further terminal,
wherein the at least one processor is further configured to transmit, via the interface and to an access node of the cellular network, an uplink report message indicative of at least one property of the at least one uplink pilot signal that was received,
wherein the at least one uplink pilot signal comprises multiple pilot signals, and
wherein the uplink report message comprises an average of the at least one property of the multiple pilot signals.
