Abstract: A paging information transmission method and a paging method in a mobile communication system are provided to transmit paging information to MSs(Mobile Stations) that does not maintain uplink synchronization to allow the MSs to perform paging based on the paging information. A BS(Base Station)(100) checks whether there is packet data or a control message to be transmitted to an MS(S100). When there is packet data or a control message, the BS checks whether the MS maintains uplink physical layer synchronization(S110). If the MS maintains the uplink physical layer synchronization, the BS configures radio resource allocation information for transmission of packet information by using an identifier of the MS(S120). The BS transmits the radio resource allocation information via a physical layer control channel and transmits a packet data block via downlink radio resource(S130). the MS searches whether the radio resource allocation information exists in a physical layer control channel(S140). If there is radio resource allocation information, the MS receives a packet data block transmitted by the BS(S150-S160). The MS generates HARQ(Hybrid Automatic Retransmit reQuest) response information and transmits it to the BS(S170,S180).
