    摘要： The present invention relates to a method of transmitting paging information and a paging method in a mobile communication system. According to the invention, in a case of starting to transmit downlink information to mobile stations that do not maintain uplink synchronization while performing a low-power-consumption operation in an active state, the start of the information transmission is informed by transmitting a medium access control (MAC) paging message to the mobile stations. In this case, the invention can inform the mobile station that the MAC paging message exists in a physical layer control channel or can transmit the generated MAC paging message through only the physical layer control channel. Accordingly, the invention can efficiently transmit the paging information while maximizing utilization of a limited radio resource.

    摘要： Provided is a method for indicating a mobile station maintaining radio resource control (RRC) connection but not maintaining uplink physical layer synchronization to receive downlink signals when packet data to be transmitted to the mobile station are generated to thereby make the mobile station start uplink signal transmission. The method includes: (a) allocating a random access preamble index and generating a downlink signal reception indication message including the allocated random access preamble index in a base station; (b) transmitting the generated downlink signal reception indication message to the mobile station; (c) forming a response message to random access, when a preamble signal designated by the random access preamble index is transmitted from the mobile station in response to the downlink signal reception indication message; and (d) transmitting the response message to random access to the mobile station to thereby control uplink physical layer synchronization.

    摘要： Provided are a sync channel of a forward link, a common pilot channel structure, and an initial cell search method and an adjacent cell search method for handover in a cellular system using orthogonal frequency division multiplexing (OFDM). A cell search method in an OFDM cellular system in which a primary sync channel and a secondary sync channel are configured based on time division multiplexing (TDM) includes acquiring sync block synchronization and a primary sync channel sequence number using a primary sync channel symbol included in a frame received by a terminal, detecting a boundary of the frame and a scrambling code group using the sync block and a secondary sync channel symbol included in the frame received by the terminal, and acquiring a scrambling code using the primary sync channel sequence number and the scrambling code group, thereby reducing cell search time with low complexity.
