Abstract: PURPOSE: A semi persistent scheduling method and apparatus thereof are provided to reduce the number of unnecessary retransmissions in the use of semi persistent scheduling. CONSTITUTION: A first RB(Resource Block)(605) shows an RU(Resource Unit) by continuous scheduling. A second RB(650) shows the RU by dynamic scheduling. The second RB receives fixed resources from the starting point of a VoIP call to the ending point of a VoIP call.

Abstract: PURPOSE: A method and a device for generating neighbor base station list using virtual coordinate in a wireless communication system are provided to recognize neighboring base station by generating a 2D virtual coordinate of one-hop base stations, correcting the 2D virtual coordinate of two-hop base stations, generating the neighboring base station list. CONSTITUTION: A central BS(Base Station) measures a signal size of neighboring base stations(203). The base station exchanges the measured signal strength information with the neighboring base stations(209). By using the measured signal size, the base station searches neighboring base stations having signal size over the reference value(215). By using the exchanged signal strength information, the base stations generated virtual coordinate about the search neighboring base stations on a 2D plane(227).
