摘要： Based on an entering condition for reporting reception quality of a cell via Measurement Report, UE (200) transmits to a radio access network the Measurement Report. The UE (200) judges numberOfTriggeringCell that triggers transmission of the measurement report to the radio access network, and transmits the Measurement Report when the number of neighbor cells that fulfill the entering condition is equal to or more than the numberOfTriggeringCell.

摘要： The present invention is designed so that mismatches in the recognition of TPC command-accumulated values between a radio base station and a user terminal are resolved in a simple way. The user terminal of the present invention provides a user terminal that transmits uplink channels, and that has a receiving section that receives transmission power control (TPC) commands from each of a plurality of cells that are grouped, a control section that controls the uplink channel transmission power of each of the multiple cells based on accumulated values of the TPC commands, and, when a reset condition is fulfilled in one of the multiple cells, the control section resets the accumulated values of all of the multiple cells.

摘要： A mobile communication method according to the present invention includes executing an RA procedure between a mobile station (UE) and a radio base station (eNB) when the mobile station (UE) in a DRX state makes a return to a non-DRX state in order to perform call origination processing. The method comprises: a step A of causing the radio base station (eNB) in the RA procedure to transmit “Call Identification Request” to the mobile terminal (UE); a step B of causing the mobile terminal (UE) in the RA procedure to notify the radio base station (eNB) of “Call Identification” in response to the “Call Identification Request”; and a step C of causing the radio base station (eNB) in the RA procedure to determine whether to allow the abovementioned return on the basis of the “Call Identification”.
