Abstract: A resource management method performed by a CP in C-RAN system includes configuring M user-centric cells for M terminals with a plurality of ANs, and determining a number K of orthogonal resource sharing groups sharing a same orthogonal resource; selecting K user-centric cells as group headers for the K orthogonal resource sharing groups, and adding the selected K user-centric cells as group headers to the K orthogonal resource sharing groups; configuring the K orthogonal resource sharing groups by sequentially adding ungrouped user-centric cells to the K orthogonal resource sharing groups; and dividing total system resources into K orthogonal resources, and mapping the divided K orthogonal resources to the K orthogonal resource sharing groups, respectively.

Abstract: Provided is a method for transmitting paging information in a cellular system. An object of the method is transmitting paging information which can improve applicability of a limited radio resource by variably and flexibly setting up and mapping a transport channel and a physical channel in order to transmit information notifying start of downlink information from a base station to a terminal in a cellular system for packet transmission. The method includes the steps of: forming a paging channel (PCH) in a transport channel corresponding to generation of paging information; setting a paging indication channel (PICH) based on the paging information and forming the paging indication channel in a radio resource of a physical layer; and allocating the paging channel to the radio resource of the physical layer.

Abstract: Provided is a method of transmitting and receiving data using a persistent allocation scheme in order to effectively support a voice service between a base station and a mobile terminal in a packet based mobile communication system. When an error occurs in transmitting control information that indicates whether to use a radio resource using the persistent allocation scheme, the base station may retransmit the control information and thereby maintain a communication quality.
