Mobile station apparatus, method, and processor of the same

Abstract

A mobile station apparatus configures first and second timers related to first and second groups. A first group of cells uses a first uplink transmission timing, and a second group of secondary cells uses a second uplink transmission timing. When the first timer of the first group has expired: all transmission HARQ buffers in association with the cells of the first group are flushed, the second timer is considered as expired, and an uplink transmission on any cells except random access preamble transmission on the primary cell is stopped. In a case where the second timer of the second group has expired: all transmission HARQ buffers in association with the secondary cells of the second group are flushed, and an uplink transmission on any cells in the second group except random access preamble transmission on the any cells in the second group is stopped.

         2 . 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 zero or more secondary cells, and a second group of one or more secondary cells uses a second uplink transmission timing, 
 in a case where the first timer of the first group has expired: 
 the second timer is considered as expired. 
   
     
     
         3 . The mobile station apparatus according to  claim 2 ,
 in a case where the first timer of the first group has expired, discards allocation information regarding all physical uplink shared channels (PUSCHs),   in a case where the second timer of the second group has expired, allocation information regarding all PUSCHs in the one or more secondary cells of the second group.   
     
     
         4 . The mobile station apparatus according to  claim 2 ,
 in a case where the first timer of the first group has expired, discards allocation information regarding all physical downlink shared channels (PDSCHs),   in a case where the second timer of the second group has expired, allocation information regarding all PDSCHs in the one or more secondary cells of the second group.
