Abstract: A method and apparatus for initiating communications on a shared channel in a mobile communication system are provided. A user equipment transmits an uplink signal for requesting communications on the shared channel to a Node B, and waits for a delay duration without monitoring a downlink after transmitting the uplink signal. When the delay duration has elapsed, the user equipment monitors the downlink during a valid period and determines whether a downlink signal responding to the uplink signal is received in a transmission time interval within the valid period. When the downlink signal is received in the valid period, the user equipment transmits and receives data on the shared channel.

Abstract: A paging apparatus and method in a mobile communication system providing an MBMS (Multimedia Broadcast Multicast Service). In the mobile communication system, to page a UE for a first service through a primary carrier during a second service in progress through a secondary carrier, a PICH (Paging Indication Channel) transmitter in a Node B transmits paging indication information to the UE through the primary carrier by oscillating the primary carrier as a transmission frequency. A PCH (Paging Channel) transmitter transmits paging information to the UE through the primary carrier or the secondary carrier by oscillating the primary carrier or the secondary carrier as the transmission frequency under a predetermined control. A PBMSCH (Physical Broadcast Multicast Shared Channel) transmitter transmits data of the second service through the secondary carrier by oscillating the secondary carrier as the transmission frequency. A controller controls the primary carrier or the secondary carrier to be oscillated as the transmission frequency of the PCH transmitter if the paging indication information indicates paging.

Abstract: A method and apparatus are provided for transmitting an uplink scheduling request in a mobile communication system. Scheduling request transmission cycles are set according to priorities between a terminal and a radio resource controlling node. The terminal transmits the scheduling request to the radio resource controlling node according to a scheduling request transmission cycle corresponding to a highest priority among priorities corresponding to uplink data or uplink control signals, if the uplink data or the uplink control signals are generated from an upper layer. The terminal receives scheduling information from the radio resource controlling node, and determines whether resource allocation information is included in the scheduling information. The terminal cyclically transmits the scheduling request to the radio resource controlling node in the scheduling request transmission cycle, if the resource allocation information is not included in the scheduling information.
