Apparatus and method for adding and deleting relay link in communication system

摘要

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.

1. A method for adding and deleting, at a User Equipment (UE), a relay link in a communication system, the method comprising:
determining whether to add the relay link based on 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, the relay station configured to relay signals between the UE and the Node-B over the relay link; determining whether to delete the relay link based on 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.
