AUXILIARY CARRIER CHANGING METHOD, TERMINAL, NETWORK EQUIPMENT AND SYSTEM

摘要

The present invention discloses a terminal, including: a receiving unit, configured to receive a secondary carrier change instruction sent by a network device, where the secondary carrier change instruction carries feature information of a changed secondary carrier; a first determining unit, configured to determine the changed secondary carrier according to the feature information, received by the receiving unit, of the changed secondary carrier; a setting unit, configured to set, according to a required state for the changed secondary carrier determined by the first determining unit, a state of the changed secondary carrier to the required state, where the required state for the changed secondary carrier includes an activated state and a deactivated state; and a second determining unit, configured to determine synchronization information of the changed secondary carrier determined by the first determining unit. According to the terminal provided in the embodiments of the present invention, during change of a secondary carrier, the terminal can set a state of the changed secondary carrier as required, which improves flexibility of state setting for the changed secondary carrier.
