Abstract

A base station including: a judging unit configured to judge whether a band to be uplink adjusted includes only a band corresponding to a primary cell; and a transmitter configured to transmit a command for the band corresponding to the primary cell when the judging unit determines that the band to be uplink adjusted includes only the band corresponding to the primary cell, such that a timer relating to an uplink synchronization for the band corresponding to the primary cell is restarted.

Claims (6)

1. A base station comprising:

a memory that stores a plurality of instructions;

a processor coupled to the memory and configured to execute the plurality of instructions to determine whether a band to be uplink adjusted includes only a band corresponding to a primary cell; and

a transmitter configured to transmit a command for the band corresponding to the primary cell when it is determined that the band to be uplink adjusted includes only the band corresponding to the primary cell, wherein, the command contains an indication of the band corresponding to the primary cell, such that a timer relating to uplink synchronization for the band corresponding to the primary cell is restarted.

2. The base station according to claim 1 , wherein

the transmitter is further configured to transmit a command for the band to be uplink adjusted and the band corresponding to the primary cell when it is determined that the band to be uplink adjusted includes a band not corresponding to the primary cell, such that a timer relating to uplink synchronization associated with the band to be uplink adjusted and the timer relating to uplink synchronization only associated with the band corresponding to the primary cell are restarted.
