摘要： A synchronous retransmission method in a mobile communication system supporting a multicast service wherein one response channel is assigned on a multicast service-by-multicast service basis, and a response signal is transmitted through the response channel only when at least one mobile terminal fails in decoding for a packet transmitted by the multicast service. Accordingly, the response signal is rapidly transferred to the packet transmitted by the multicast service, and overhead from to the response channel can be reduced.

摘要： A method and apparatus optimize handover optimization in a broadband wireless communication system. Operations of a base station includes determining whether at least one of a plurality of time intervals included in a total time taken by handover, exceeds a threshold time. Whether to advance or delay a handover point is determined based on which at least one of the time interval exceeds the threshold time. And at least one handover parameter is changed to advance or delay the handover point.

摘要： Disclosed is a symbol synchronization method in an OFDM-based communication system which includes multiple access nodes supporting wireless connection of terminals, supports multi-connection of each terminal for the access nodes and performs synchronization by means of a cyclic prefix. The symbol synchronization method includes monitoring connection of a new access node; setting a number of times by which the new access node transmits equal symbols and a number of times by which at least one existing access node transmits the equal symbols when the connection of the new access node is detected; transmitting the equal symbols by the determined number of times by each access node; and performing synchronization by means of the symbols received from the access nodes by the terminal.
