Apparatus and method for adding and deleting relay link in communication system
First Claim
1. A method for adding and deleting, at User Equipment (UE), a relay link in a communication system, the method comprising:
- determining whether to add the relay link with consideration of at least one of a movement velocity of the UE, a signal intensity of a Node-B and at least one relay station, and a channel state value of the UE;
transmitting a message requesting addition of the relay link to a relay station corresponding to the relay link whose addition has been determined in response to determining to add the relay link;
determining whether to delete the relay link with consideration of at least one of a movement velocity of the UE, a signal intensity of a Node-B and at least one relay station, and a channel state value of the UE; and
transmitting a message informing deletion of the relay link to a relay station corresponding to the relay link whose deletion has been determined in response to determining to delete the relay link.

Abstract
An apparatus and a method effectively adds and deletes a relay link in a communication system that includes a multiple relay system. The apparatus and method include determining by a relay mode controller whether to add or delete the relay link with consideration of at least one of a movement velocity of User Equipment (UE), a signal intensity of a Node-B and at least one relay station, and a channel state value of the UE. When addition or deletion of the relay link is determined, a message requesting addition of the relay link or a message informing deletion of the relay link is transmitted by a signaling processor to a relay station corresponding to the relay link whose addition or deletion has been determined.

11. A method for controlling, at a relay station, addition of a relay link in a communication system, the method comprising:
-
when a request message requesting addition of the relay link is received from a User Equipment (UE), determining whether to accept addition of the relay link based on a total transmit carrier power; and transmitting a response message comprising information as to whether the addition of the relay link is accepted to the UE. - View Dependent Claims (12)

13. An apparatus of User Equipment (UE) for adding and deleting a relay link in communication system, the apparatus comprising:
-
a relay mode controller configured to determine whether to add the relay link with consideration of at least one of a movement velocity of the UE, a signal intensity of a Node-B and at least one relay station, and a channel state value of the UE and determine whether to delete the relay link with consideration of at least one of a movement velocity of the UE, a signal intensity of a Node-B and at least one relay station, and a channel state value of the UE; and a signaling processor configured to generate a message requesting addition of the relay link when addition of the relay link is determined and generate a message informing deletion of the relay link when deletion of the relay link is determined, wherein the message requesting addition of the relay link or the message informing deletion of the relay link are transmitted to a relay station corresponding to the relay link. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)

23. An apparatus of a relay station, for controlling addition of a relay link in a communication system, the apparatus comprising:
-
a relay mode determining unit configured to, when a message requesting addition of the relay link is received from User Equipment (UE), determine whether to accept addition of the relay link using total transmit carrier power; and a signaling processor configured to generate a message to be transmitted to the UE, the message comprising information as to whether the addition of the relay link is accepted. - View Dependent Claims (24)
