(54) MOBILE COMMUNICATION METHOD AND MOBILE STATION


(57) The present invention avoids a situation where PDCCH and PUSCH resources for transmitting a "PDCP status report" are wasted, even when a "PDCP re-establishment procedure" is started. A mobile communication method of the present invention comprises the steps of: causing a mobile station UE to discard a "PDCP status report #1" and generate a "PDCP status report #2" when detecting a start trigger for a "PDCP re-establishment" again before completing transmission of the "PDCP status report #1"; and causing the mobile station UE to transmit the "PDCP status report #2" to a radio base station eNB after completing the "PDCP re-establishment".
