Abstract

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.

Claims

1. A mobile station apparatus comprising:

a memory and a processor in electrical communication with the memory, the processor executing instructions stored in the memory to;

configure a first timer related to a first group and a second timer related to a second group, wherein a first group of one or more cells uses a first uplink transmission timing, the one or more cells includes a primary cell, and a second group of one or more secondary cells uses a second uplink transmission timing,

in a case where the first timer for the first group is expired, consider the second timer is expired, and stop an uplink transmission on any cells except random access preamble transmission on the primary cell; and

in a case where the second timer for the second group expired, stop uplink transmission on any cells in the second group except random access preamble transmission on the any cells in the second group.

2. A method of a mobile station apparatus comprising;

configuring a first timer related to a first group and a second timer related to a second group, wherein a first group of one or more cells uses a first uplink transmission timing, the one or more cells includes a primary cell, and a second group of one or more secondary cells uses a second uplink transmission timing,

in a case where the first timer for the first group is expired, considering the second timer is expired, and stopping an uplink transmission on any cells except random access preamble transmission on the primary cell; and

in a case where the second timer for the second group expired, stopping uplink transmission on any cells in the second group except random access preamble transmission on the any cells in the second group.
