COMMUNICATION METHOD USING DUPLICATED ACKNOWLEDGEMENT

摘要

Communication methods using duplicated acknowledgement (ACK) are provided. A communication method of a serving base station includes determining if a handover of a device attached to the serving base station is required, and, if the handover is required, transmitting two or more duplicated ACKs to a fixed host. The two or more duplicated ACKs have the same identifier as a final ACK transmitted from the device to the fixed host. This method can alleviate an unnecessary reduction in transmission rate caused by timeout that may occur during handover of the device.
