摘要:
The present invention relates to a method for transmitting uplink control information in a mobile communication system; and, more particularly, to a method for effectively forming uplink control information transmitted through a downlink from a base station to a terminal in a mobile communication system for providing a packet service and transmitting the uplink control information with minimum radio resources occupied. The method includes the steps of generating uplink control information; allocating the uplink control information to a downlink-shared radio resource for packet data transmission based on downlink scheduling information; and transmitting the radio resource to a terminal. The present invention is applied to a mobile communication system.

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.

Provided is a method for transmitting and receiving multimedia broadcast multicast service (MBMS) data in a packet based cellular system. The method for transmitting multimedia broadcast multicast service (MBMS) to a plurality of mobile stations in a packet based cellular system, includes the steps of : a) transmitting scheduling information of transmission data, b) hybrid automatic repeat request (HARQ) information, and a service group identifier (ID) for MBMS to the mobile stations through a MBMS dedicated control channel; b) transmitting information about a dedicated feedback channel of a mobile station and unique scrambling codes different by cells and mobile stations to the mobile stations; c) transmitting a MBMS data packet to the mobile station; d) transmitting radio resource information of data retransmitted using a downlink control signal to the mobile stations if negative acknowledgment (NACK) is received from at least one of the mobile stations; and e) transmitting the retransmitted data to the mobile stations.

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.

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.
