摘要： In a mobile station that performs communication with a base station device via a plurality of cells, the plurality of cells are grouped into a first group constituted by cells having an uplink transmission timing that is the same as that of one primary cell and a second group constituted by one or more cells having an uplink transmission timing that is different from that of the primary cell. The uplink transmission timings are each managed using a corresponding transmission timing timer for each of the groups. In a case where a transmission timing timer for the first group has expired, the mobile station stops all uplink transmissions in the plurality of cells. In a case where a transmission timing timer for the second group has expired, the mobile station stops uplink transmissions in the cells constituting the second group for which the transmission timing timer has expired.

摘要： A mobile station (MS) performs a measurement of cells on a plurality of downlink frequencies used for a connection with a base station apparatus. The MS also detects a first indication or a second indication, based on the measurement of each cell designated by the base station apparatus, the first indication indicating a measurement result of a cell becomes lower than a first threshold and the second indication indicating a measurement result of a cell becomes higher than a second threshold. In addition, the MS, in a case where a reconnection procedure is started by expiring a timer corresponding to the each cell, selects a cell, and initiates a random access procedure for requesting a reconnection in the selected cell. Further, the timer is started if the first indication is indicated consecutively for a certain number of times.
