METHOD FOR COMMUNICATING FOR RESOURCE OPTIMIZATION IN COMMUNICATION SYSTEM)CONTROLLING SERVICE CONTINUITY IN COMMUNICATION SYSTEM

摘要

The present invention relates to a communication method for resource optimization, and more specifically to a communication method to optimize wireless resources in a wireless communication system including a centralized base station and a relay base station. A communication method according to an embodiment of the present invention comprises: a step that a transmitter to optimize resources in a communication system checks whether a terminal is in a stereoscopic handover state including a base station and at least one relay base stations within an active set corresponding to a communication-capable base station group of the terminal; and a step that the terminal receives a retransmission request from a receiver when the terminal is in the stereoscopic handover state and retransmits packets by cooperating with at least one relays locating between the transmitter and receiver.
