Abstract: A method for allocating radio resources for data transmission in a packet-based mobile communication system and a method for transmitting data therein are provided to minimize the usage of a control channel by allocating radio resources of uplink and downlink data channels in a persistent allocation method at a connection setup time for a packet service and transmitting data through persistently allocated resources. A base station allocates terminal identifiers to UEs(User Equipments) respectively. Based on a control message delivered from an upper layer, the base station transmits information associated with the allocation of uplink/downlink RBs(Resource Blocks) and the location information of the uplink/downlink RBs to a specific UE and allocates a persistent RB. The base station encodes the allocated persistent RB in order to transmit data to the specific UE through the persistent RB.

Abstract: A method for reporting measurement information in a packet-based communication system is provided to enable a UE(User Equipment), which is executing a low power consumption operation in an active state, to measure and report information about a serving cell and neighbor cells according to a measurement report parameter in order to support handover. A UE receives neighbor node B information and handover-associated threshold information from a serving node B(401). The serving node B carries out an RRC(Radio Resource Control) connection to provide a packet service together with the UE(402). Then the serving node B determines a DRX/DTX operation while providing the packet service(403). At this moment, the serving node B negotiates with the UE on DRX/DTX parameters and a measurement report parameter(404,405), and notifies the UE of the determined parameters(406). Based on the determined parameters, the UE measures and reports information about the serving cell and neighbor cells while executing the DRX/DTX operation(407).
