Abstract

Provided are a method for reporting a state of a relay function for another network node in a radio communication system and an apparatus using the method. The method detects a state of a relay function of a first network node and transmits a report for the detected state of the relay function to a second network node.

First claim

What is claimed is:

1 . A method for reporting a state of a relay function performed by a user equipment (UE), the method comprising:
detecting a state of a relay function state of a first network node; and transmitting a report for the detected state of the relay function to a second network node.

2 . The method of claim 1 , wherein the first network node is another UE to providing a relay function to the UE, and the second network node is another UE or a base station close to the UE.

3 . The method of claim 1 , further comprising receiving configuration information on a relay function state report.

4 . The method of claim 3 , wherein the configuration information comprises at least one of a detection target of the UE and a performing condition of transmission of the report.

5 . The method of claim 4 , wherein the configuration information further reports information to be included in the report.

6 . The method of claim 4 , wherein the configuration information further comprises information to report a reception target of the report.

7 . The method of claim 1 , further the detecting of the state of a relay function state of a first network node comprises detecting the state of a relay function state of the first network node based on relay function state information transmitted from the first network node.

8 . The method of claim 1 , wherein the report comprises generation of a specific event as a performing condition.

9 . The method of claim 8 , wherein the information to be included in the report comprises at least one of an identity (ID) of the first network node, an ID of an event satisfying the performing condition of the report, and an ID of the UE.

10 . A user equipment (UE), the UE comprising:
an RF unit configured to send and receive radio signals; and a processor connected to the RF unit to be operated,
wherein the processor detects a state of a relay function state of a first network node; and
transmits a report for the detected state of the relay function to a second network node.
