Abstract

Method for a communication device is disclosed. The method comprises being configured with at least one uplink carrier and at least one downlink carrier according to a carrier aggregation configuration, receiving, by the communication device, at least one control signal at at least one downlink control channelon the at least one downlink carrier, determining, by the communication device, at least one control format of the at least one control signal for at least one of at least one uplink and at least one downlink transmission or for at least one control signaling carried on the same or different at least one uplink carrier or the at least one downlink carrier, and performing, by the communication device, at least one of the at least one uplink and the at least one downlink transmission or at least one control signalingon the same or different at least one uplink carrier or the at least one downlink carrier according to the at least one control format of the at least one control signal, wherein the at least one of at least one uplink and the at least one downlink transmission or the at least one control signaling use a same or different transmission modes on the same or different at least one uplink carrier or the at least one downlink carrier.

Description

[0001] This application corresponds to US Priority Application No. 60 / 321,691, filed April 7, 2010, and is incorporated herein by reference in its entirety. technical field [0002] The present invention relates to power control, in particular to a communication system and its communication method for providing multi-carrier power control. Background technique [0003] The Long Term Evolution (LTE) or Long Term Evolution-Advanced (LTE-A) system is a new generation wireless communication system proposed by the 3rd Generation Partnership Project (3GPP). A user equipment (UE) compatible with the LTE / LTE-A system can simultaneously transmit and receive data on one or more component carriers. The LTE-A system provides high-speed low-latency packet communication. Through carrier aggregation technology, up to five groups of 20 megahertz (MHz) component carriers can be aggregated to achieve a data rate of up to 100 megabits per second (Mbps). The LTE-A system can operate under symm...
