COMMUNICATION METHOD USING A CARRIER AGGREGATION AND APPARATUS THEREFORE

摘要

A method of controlling an uplink transmission in a wireless communications system, and a user equipment therefore are discussed. The method according to one embodiment includes configuring the user equipment with multiple component carriers; receiving first configuration information for allocating one or more component carrier sets; receiving second configuration information for periodically transmitting an uplink signal; receiving control information for configuring states of component carriers, by which a downlink component carrier and an uplink component carrier are controlled to be in a same state; and performing a procedure for periodically transmitting the uplink signal on an uplink component carrier in use of the first configuration information, the second configuration information and the control information. When the uplink component carrier is in the active state, a transmission of the uplink signal is performed. When the uplink component carrier is in the non-active state, the transmission of the uplink signal is skipped.

1. A method of controlling an uplink transmission at a user equipment in a wireless communications system, the user equipment being configured with multiple component carriers, the method comprising:
receiving first configuration information for allocating one or more component carrier sets, wherein each of the one or more component carrier sets includes a downlink component carrier and an uplink component carrier paired with the downlink component carrier; receiving second configuration information for periodically transmitting an uplink signal; receiving control information for configuring states of component carriers, by which a downlink component carrier and an uplink component carrier paired with the downlink component carrier in a component carrier set are controlled to be in a same state among the active/non-active states; and performing a procedure for periodically transmitting the uplink signal on an uplink component carrier in use of the first configuration information, the second configuration information and the control information, wherein when the uplink component carrier is in the active state at a time for transmitting the uplink signal, a transmission of the uplink signal is performed on the uplink component carrier at the time for transmitting the uplink signal, and wherein when the uplink component carrier is in the non-active state at a time for transmitting the uplink signal, the transmission of the uplink signal is skipped on the uplink component carrier at the time for transmitting the uplink signal.
